Step-by-step explanation:

The midnight temprature is 5 °C and the temprature is decreasing at the rate of 2°C per hour . If T is the hours past midnight then after t hours the temprature will be ( 5t-2t) . If the temprature is colder than -4°C right now , then your inequality can be written like 5t-2t<-4

The side length of BC in ∠ABC is 11.

Solution:

∠A = 32°

∠C = 39°

∠B = 180°-39°-42°

∠B = 99°

side length of AC = 16

a / sin A = b / sin B = c / sin C

a / sin42° = 16 / sin99°

a = 16 sin42°/ sin99°

a = 10.84

a = 11

The side length of BC = 11

Answer:

I'll let you figure it out.

Step-by-step explanation:

A. First you separately take each of the two fractions and you multiply both sides to get the same denominator (bottom half of the fraction) for the two fractions, and then you combine the numerators (top half of the fraction) together while keeping the same denominator (simplify if needed). That's the fraction of students who don't walk home (answer for B). Then change the numerator to the (denominator - the numerator), and keep the same denominator, then simplify if needed (answer for C). This whole paragraph is the answer for A (but write it as your own words if you can).

The factor of the expression will be (x + 1) and (x + 1). Then the product of two binomials will be (x + 1) and (x + 1).

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The expression is given below.

The top right graph could show the arrow's height above the ground over time.

The initial and the final height are both at eye level, which is the reference height, that is, a height of zero.

This means that the beginning and at the end of the graph, it is touching the x-axis, hence either the top right or bottom left graphs are correct.

The trajectory of the arrow is in the format of a concave down parabola, hitting it's maximum height and then coming back down to eye leve.

Hence the top right graph could show the arrow's height above the ground over time.

True, free bilirubin is transported by the blood to the liver.

Macrophages begin the disposal of hemoglobin by separating the heme from the globin. They hydrolyze the globin into free amino acids, which can be used for energy-releasing catabolism or recycled for protein synthesis.

Bilirubin

Bilirubin is a red-orange compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells.

Hemoglobin

Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs.

Answer:

The height of the bullding is 717 ft

Step-by-step explanation:

Right Triangles

The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.

The tangent ratio for an internal angle A is:

\(\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}\)

The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.

The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:

\(\displaystyle \tan 82^\circ=\frac{h}{100}\)

Solving for h:

\(h = 100\tan 82^\circ\)

Computing:

h = 711.5 ft

We must add the height of Ms, M's eyes. The height of the building is

711.5 ft + 5 ft = 716.5 ft

The height of the building is 717 ft

The required compound interest is 4% which is paid per year.

Given that,
An expression of compound interest problem is given V = 1750 * 1.04ˣ, we have to determine the compounded interest rate.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
An expression of compound interest problem is given V = 1750 * 1.04ˣ,
where 1.04 represents 1 + r
So,
1 + r/100 = 1.04
r = 0.04 * 100
r= 4%

Thus, the required compound interest is 4% which is paid per year.

Answer:

Step-by-step explanation:

A triangle can only be a triangle if the two shortest sides add up to be greater than the longest side.

For example on the first one, the segments 1 2 and 3 will not make a triangle as 1 + 2 = 3 and if the two smallest sides of a triangle are equal to the longest side it will not be a triangle at all.

So to make this easy, out of the three numbers given: add the two smallest numbers. This number has to be greater than the third number given, and it cannot be equal.

For question three: 3+9 = 12

And 12 is greater than 11, therefore this can make a triangle.

Answer:

\(\dfrac{1}{729}\)

Step-by-step explanation:

\(\left(\dfrac{}{}(-3)^2\dfrac{}{}\right)^{-3}\)

First, we should evaluate inside the large parentheses:

\((-3)^2 = (-3)\cdot (-3) = 9\)

We know that a number to a positive exponent is equal to the base number multiplied by itself as many times as the exponent. For example,

\(4^3 = 4 \, \cdot\, 4\, \cdot \,4\)

       ↑1 ↑2 ↑3 times because the exponent is 3

Next, we can put the value 9 into where \((-3)^2\) was originally:

\((9)^{-3}\)

We know that a number to a negative power is equal to 1 divided by that number to the absolute value of that negative power. For example,

\(3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{3\cdot 3} = \dfrac{1}{9}\)

Finally, we can apply this principle to the \(9^{-3}\):

\(9^{-3} = \dfrac{1}{9^3} = \boxed{\dfrac{1}{729}}\)

Axis of symmetry

Answer:

axis of symmetry: x = 2

vertex:  (-2, 13)

Step-by-step explanation:

Given function

\(\sf y=6x^2-24x+11\)

Vertex form

\(\sf y=a(x-h)^2+k\)
where (h, k) is the vertex

Expand vertex form:

\(\sf \implies y=ax^2-2ahx+ah^2+k\)

Compare coefficients of expanded vertex form with given function:

coefficient of \(\sf x^2\):  

⇒ a = 6

coefficient of \(\sf x\):  

⇒ -2ah = -24

⇒ ah = 12

⇒ 6h = 12

⇒ h = 2

constant:

⇒ \(\sf ah^2+k=11\)

⇒ \(\sf 6 \cdot 2^2+k=11\)

⇒ \(\sf 24+k=11\)

⇒ \(\sf k=-13\)

Vertex

Vertex = (2, -13)

Axis of symmetry

Axis of symmetry is when x = h

Therefore, axis of symmetry is x = 2

In an isosceles right triangle, the equal sides make the right angle. They have the ratio of equality, 1 : 1. To find the ratio number of the hypotenuse h, we have, according to the Pythagorean theorem, h2 = 12 + 12 = 2

The triangle is an Isosceles triangle.

We need to find the angles across from the legs are called what angles?

An isosceles triangle is a triangle which has two congruent sides.

The congruent sides of the isosceles triangle are called the legs.

The other side is called the base.

The angles between the base and the legs are called base angles.

The angle made by the two legs is called the vertex angle.

One of the important properties of isosceles triangles is that their base angles are always congruent. This is called the Base Angles Theorem.

Hence in an isosceles triangle with two congruent sides the angles across from the legs are called as Base angles.

a) Yes, It does. The scatterplot support the newspaper report about number of semesters and starting salary.

b) The value is relatively low, indicating that there are other factors that also contribute to starting salary.

c) The correlation coefficient is a value between -1 and 1 that measures the strength and direction of the linear association between two variables.

a) The scatterplot appears to show a positive association between the number of semesters needed to complete an academic program and the starting salary in the first year of a job. As the number of semesters increases, the starting salary generally increases as well. Therefore, the scatterplot supports the newspaper report.

b) The coefficient of determination, or R-squared value, represents the proportion of the variation in the dependent variable (starting salary) that is explained by the independent variable (number of semesters). A value of 0.335 means that 33.5% of the variation in starting salary is explained by the number of semesters. This value is relatively low, indicating that there are other factors that also contribute to starting salary.

c) The correlation coefficient is a value between -1 and 1 that measures the strength and direction of the linear association between two variables. A value of 1 indicates a perfect positive correlation, a value of -1 indicates a perfect negative correlation, and a value of 0 indicates no correlation. The correlation coefficient for this data is not provided in the problem, so it is not possible to determine it.

The correct values for a, b, c, d, and e are a = 16, b = 29, c = 24, d = 22, and e = 30 for group of 75 students on asking whether they like Algebra or Geometry.

For the values of a, b, c, d, and e, we can use the information provided in the table. Let's break it down step-by-step:

We are given that a total of 75 math students were surveyed. Therefore, the total number of students should be equal to the sum of the students who like algebra, the students who like geometry, and the students who do not like either subject.

75 = 45 (Likes Algebra) + 53 (Likes Geometry) + 6 (Does Not Like Either)

Simplifying this equation, we have:

75 = 98 + 6

75 = 104

This equation is incorrect, so we can eliminate options c and d.

Now, let's look at the information given for the students who do not like geometry. We know that a + b = 6, where a represents the number of students who like algebra and do not like geometry, and b represents the number of students who do not like algebra and do not like geometry.

Using the correct values for a and b, we have:

16 + b = 6

b = 6 - 16

b = -10

Since we can't have a negative value for the number of students, option a is also incorrect.

The remaining option is option e, where a = 29, b = 16, c = 24, d = 22, and e = 30. Let's verify if these values satisfy all the given conditions.

Likes Algebra: a + c = 29 + 24 = 53 (Matches the given value)

Does Not Like Algebra: b + d = 16 + 22 = 38 (Matches the given value)

Likes Geometry: c + d = 24 + 22 = 46 (Matches the given value)

Does Not Like Geometry: b + e = 16 + 30 = 46 (Matches the given value)

All the values satisfy the given conditions, confirming that option e (a = 29, b = 16, c = 24, d = 22, and e = 30) is the correct answer.

The angle between the first and second polarizers is 90°, which means that the output light will be horizontally polarized and the intensity of the output light is 18.75 W/m².

The output (transmitted) light is linearly polarized along the direction determined by the angle between the two polarizers. The intensity of the output light can be determined using Malus's law, which states that the intensity of light transmitted through a polarizer is proportional to the square of the cosine of the angle between the polarization direction of the incident light and the transmission axis of the polarizer.

θ₁ =  30°

θ₂ =  60°

The angle between the first and second polarizers is 30° + 60° = 90°.

Therefore, the output light will be horizontally polarized.

Let's denote the intensity of the incident light as I₀.

The first polarizer at an angle of 30° with respect to the vertical will transmit light with an intensity of I₁ = I₀× cos²(30°) = I₀× (3/4).

The second polarizer at an angle of 60° with respect to the vertical will transmit light with an intensity of I₂ = I₁ × cos²(60°) = I₁ × (1/4) = I₀ × (3/16).

Therefore, the intensity of the output light is I₂ =  I₀ × (3/16), which is 3/16 times the intensity of the incident light.

In this case, since the incident intensity is given as I = 100 W/m², the intensity of the output light will be I₂ = (3/16) × 100 W/m² = 18.75 W/m².
