Answer:

B

Step-by-step explanation:

The sections of the parallel roads split by the transversals are in proportion, that is

\(\frac{350}{300}\) = \(\frac{first}{1650}\) ( cross- multiply )

300 first = 577500 ( divide both sides by 300 )

first = 1925 ft

Thus

Elm st → Maple st = 1925 + 350 = 2275 ft → B

Answer:

A, 152 cm.

Step-by-step explanation:

A rectangular pyramid has a volume equation of

V = (lwh)/3.

Therefore, when we plug the values in:

[(7)(5)(13)]/3 = V

V = 455/3

V = 151.666667

V is approximately equal to 152 cm^3.

Step-by-step explanation:

The volume of the resulting prism is 3.375 times of original volume.

The factor by which the dimensions of an object are enlarged is called the scale factor.

Let us take the base area of Prizm = a²

Height of the prism = h

Enlarged area = (scale factor)² * previous area

Enlarged area = 1.5²*a² = 2.25a²

Enlarged height = 1.5h

So, enlarged volume = enlarged area* enlarged height

Enlarged volume= 2.25a²*1.5h = 3.375a²h

Enlarged area/previous area = 3.375a²/a² = 3.375

Therefore, the volume of the resulting prism is 3.375 times of original volume.

Answer:

Future population = 720800

Step-by-step explanation:

Below is the calculation of population after 15 years.

Given the present population = 340000

Growth in population = 5.25%

Use below formula to find the values:

Future population = Present population ( 1 + r)^n

Future population = 340000 ( 1 + 5.25%)^15

Future population = 340000 (2.15)

No, the line x=1-2t, y=2+5t, z=-3t is not parallel to the plane 2x+y-z=8 as their dot product is not zero.

To determine if the line x = 1 - 2t, y = 2 + 5t, z = -3t is parallel to the plane 2x + y - z = 8, we can find the direction vector of the line and check if it is orthogonal to the normal vector of the plane.

The direction vector of the line is given by the coefficients of t in each component, which is (-2, 5, -3).

The normal vector of the plane is given by the coefficients of x, y, and z in the plane's equation, which is (2, 1, -1).

To check if the direction vector is orthogonal to the normal vector, we can take their dot product and see if it is zero:

(-2, 5, -3) * (2, 1, -1) = -4 + 5 + 3 = 4

Since the dot product is not zero, the direction vector of the line and the normal vector of the plane are not orthogonal, which means the line is not parallel to the plane.

The line x = 1 - 2t, y = 2 + 5t, and z = -3t is not parallel to the plane 2x + y - z = 8, hence the answer is no.

The vectors =−6 3 and = 6 6 are not orthogonal because they have different magnitude.

Orthogonal vectors are two vectors that are perpendicular to each other, meaning they form a 90-degree angle.

As we all know that when two vectors have the same magnitude and are orthogonal, they are said to be orthonormal.

To find all numbers and for which the vectors =−6 3 and = 6 6 are orthogonal and have the same magnitude, we first need to find the magnitude of each vector.

For the first vector, =−6 3,

the magnitude is

=> √(−6)² + (3)²

=>  √(36 + 9) = √45

=> 3√5.

For the second vector, = 6 6,

the magnitude is

=> √(6)² + (6)² = √(36 + 36)

Each of these possible roots using Synthetic division or long division, we find that none of them are actually roots of the Polynomial function F(x). Therefore, none of the options A, B, C, or D is a possible root of the function.

The rational root theorem is a method used to identify possible rational roots of a polynomial function with integer coefficients. The theorem states that if a polynomial function has a rational root, then it must be of the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

For the polynomial function F(x) = 3x³ - x² + 4x + 5, the constant term is 5 and the leading coefficient is 3. Therefore, the possible rational roots are of the form p/q, where p is a factor of 5 and q is a factor of 3.

The factors of 5 are ±1 and ±5, and the factors of 3 are ±1 and ±3. Therefore, the possible rational roots are ±1/3, ±5/3, ±1, and ±5.

Checking each of these possible roots using synthetic division or long division, we find that none of them are actually roots of the polynomial function F(x). Therefore, none of the options A, B, C, or D is a possible root of the function.

Answer:

-64

Step-by-step explanation:

The option that gives the correct answer when we evaluate p(2) of the given polynomial is; Option D; P(2) = -64

We are given the polynomial;

p(x) = 9x⁴ - 45x³ + 37x² + x + 2

We are told he wants to determine the remainder by evaluating p(2). This means we will plug in 2 for x in the polynomial to get the remainder.

Thus;

p(2) = 9(2)⁴ - 45(2)³ + 37(2)² + 2 + 2

p(2) = 9(16) - 45(8) + 37(4) + 4

p(2) = 144 - 360 + 148 + 4

p(2) = -64

Answer:

sinθ = -3/5, Quadrant IV (Option B)

Step-by-step explanation:

Let's first find the sine

cosθ = adj./hyp.

Pythagorean theorem (in terms of right triangle trig) = (opp)^2 + (adj)^2 = (hyp)^2

Plug in the adjacent and hypotenuse

(opp.)^2 + 16 = 25

solve for the opposite side

opp. = 3

To find the quadrant, recall the sin <0, so the sin has to be negative.

So, your sine value is -3/5.

Sine is negative at Quadrants III and IV, so eliminate C and D.

Since your cosine value is positive, it is at Quadrant IV (Cosine is positive at the first and fourth quadrants.)

Therefore, Option B is correct.

What is Null hypothesis?

Null hypothesis (H0) is a statistical hypothesis that states there is no significant difference or relationship between the population parameter and the sample statistic being tested, or no effect of the treatment or intervention being evaluated. It is usually the hypothesis that is initially assumed to be true before the statistical test or experiment is conducted, and is compared against the alternative hypothesis to determine whether the results are statistically significant.

(a) If you represent the manufacturer and want to support the claim that the mean life of its refrigerators is greater than 15 years, the null hypothesis would be:

Null hypothesis (H0): The mean life of the refrigerators is less than or equal to 15 years.

Alternative hypothesis (Ha): The mean life of the refrigerators is greater than 15 years.

Step-by-step explanation:

An image that creates represents this situation has been attached to this answer. As one can see, the diagram models the situation, the angle of depression represents the angle between the horizon line and the line of sight. The horizon line and the tower form a right angle (a (90) degree angle). This means that the angle of depression is complementary to the angle of sight. Therefore, one can state the following:

\((angle\ of\ depression) + (angle\ of \ sight)=90\)

Substitute,

\((angle\ of\ depression) + (angle\ of \ sight)=90\)

\((m<ABD)+(m<DBC)=90\)

\(42+(m<DBC)=90\)

Inverse operations,

\(42+(m<DBC)=90\)

\(m<DBC=48\)

Now one can use the right angle trigonometric ratios to solve this problem. The right angle trigonometric ratios are a series of ratios that describe the relationship between the sides and angles in a right triangle. These ratios are as follows:

\(sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\)

Bear in mind, the terms (opposite) and (adjacent) are subjective, and change depending on the reference angle. However, the term (hypotenuse) refers to the side opposite the right angle and is constant regardless of the reference angle.

In this case, one has found an angle in the triangle, one is given the measure of the side opposite this angle, and one is asked to find the side adjacent to this angle. Therefore, it would make the most sense to use the ratio tangent (tan).

\(tan(\theta)=\frac{opposite}{adjacnet}\)

Substitute,

\(tan(48)=\frac{180}{adjacent}\)

Inverse operations,

\(tan(48)=\frac{180}{adjacent}\)

\(adjacent=\frac{180}{tan(48)}\)

\(adjacent=162.07\)
