Step-by-step explanation:

Remark

You should edit the question. The way you wrote it, , it looks like you have to square two binomials. That isn't the way it is given I don't think. You are told that A and B are supplementary. That means

A+B = 180

Equation

(8x + 6) + (7x + 24) = 180          Remove the brackets

Solution

8x + 6 + 7x + 24 = 180              Collect like terms

15x + 30 = 180                           Subtract 30 from both sides

15x = 180 - 30

15x = 150                                   Divide by 15

x = 150 / 15

x = 10

Answer

What you need is <B

<B = 7x + 24

<B = 7*10 + 24

<B = 70 + 24

<B = 94

Step-by-step explanation:

Pretty sure it's true.

Answer:

Volume = 261.8 cm³

Surface area = 254.2 cm²

Step-by-step explanation:

To calculate the volume of the cone, we have to use the following formula:

\(\boxed{V = \frac{1}{3} \pi r^2 h}\),

where:

V ⇒ volume

r ⇒ radius = 5 cm

h ⇒ height = 10 cm

Using the above formula and the provided measures, we get:

V = \(\frac{1}{3}\) × π × (5)² × 10

    = \(\frac{1}{3}\) × π × 25 × 10

      = 261.8 cm³

In order to calculate the surface area of the cone, we have to use the following formula:

\(\boxed{SA = \pi r^2 + \pi r l}\)

where:

SA ⇒ surface area

r ⇒ radius = 5 cm

l ⇒ slant length = \(\sqrt{r^2+h^2}\) = \(\sqrt{5^2+10^2}\) = 5√5 cm

Using the formula,

SA = π × (5)² + π × 5 × 5√5

     = π × 25 + π × 25√5

     = 254.2 cm²

Answer

The result of 48 - 36 is 12. Then, if you divide 12 by 36, the result is 0.3333 or 1/3.

Step-by-step explanation:

The function g(x) does not pass through the origin

Functions are ordered pairs, equations, tables, relations and graphs that relate the relationship between two or more quantities

The equation of the function is given as:

\(g(x) = \sqrt{\cos\left(x\right)}\cdot\cos\left(300x\right)+\sqrt{\left|x\right|}-0.3\left(4\ -x^2\ \right)^{0.001}\)

Next, we plot the graph of the function g(x)

See attachment for the graph of function g(x)

From the attached graph, we can see that function g(x) does not pass through the origin;

The process of conversion of fraction to percentage has been explained.

What is fraction and percentage?

Suppose there is a whole collection of objects and some parts of the objects are taken from the whole collection. Fraction represents those parts which are taken. In other words, part of a whole is called fraction. The upper part of the fraction is the numerator and the lower part of the fraction is the denominator.

If a number is taken as fraction of 100 then the fraction is known as percentage.

To convert a fraction into percentage, we have to simply multiply the fraction with 100.

For example.

Suppose we have a fraction \(\frac{1}{4}\), we need to convert  \(\frac{1}{4}\) to percentage.

So on multiplying \(\frac{1}{4}\) by 100, we obtain = \(\frac{1}{4} \times 100\) = 25%

So, \(\frac{1}{4}\) is equivalent to 25%

Step-by-step explanation:

You multiply $7.26 by 17.

The values of the triangle are approximately: B ≈ 75.33°, C ≈ 4.67°, and b ≈ 9.91.

To solve the triangle using the Law of Sines, we can use the formula:

a/sin(A) = c/sin(C)

Given that A = 100°, a = 122, and c = 10, we can substitute these values into the equation:

122/sin(100°) = 10/sin(C)

To find sin(C), we rearrange the equation:

sin(C) = (10 * sin(100°)) / 122

Using a calculator, we can evaluate sin(100°) ≈ 0.9848:

sin(C) = (10 * 0.9848) / 122

sin(C) ≈ 0.0813

To find the value of angle C, we take the inverse sine (sin⁻¹) of 0.0813:

C ≈ sin⁻¹(0.0813)

C ≈ 4.67°

Now, to find angle B, we can use the fact that the sum of the angles in a triangle is 180°:

B = 180° - A - C

B = 180° - 100° - 4.67°

B ≈ 75.33°

Finally, to find side b, we can use the Law of Sines again:

b/sin(B) = c/sin(C)

b/sin(75.33°) = 10/sin(4.67°)

Solving for b:

b = (10 * sin(75.33°)) / sin(4.67°)

b ≈ 9.91

Therefore, the values of the triangle are approximately: B ≈ 75.33°, C ≈ 4.67°, and b ≈ 9.91.

(c) the point estimate for the mean increase in happiness for the treatment group is 2 with a margin of error of 0.395.

(a) The independent variable in this study is writing positive statements or not, as this is the variable being manipulated to see its effect on the participants' happiness.

(b) The dependent variable in this study is the participants' happiness, as it is being measured to see if it is affected by the manipulation of the independent variable.

(c) Since the point estimate for the mean increase in happiness for the treatment group is:

9 - 7 = 2

The margin of error of the point estimate can be found;

Margin of error = z*(s√(n))

Where z is the z-score for the 90% confidence level, s is the standard deviation, and n is the sample size.

From the z-table, the z-score for the 90% confidence level will be 1.645.

Substituting the values;

Margin of error = 1.645*(1.2√(25))

Margin of error = 0.395

The probability of finding oil (to 1 decimal) is 0.7.

Probability is a statistic that is used to show the possibility or chance that a certain event will occur. Probabilities can be expressed as fractions from 0 to 1, in contrast to percentages from 0% to 100%. The four main types of probability that mathematicians study are axiomatic, classic, empirical, and subjective. Given that the terms potential and probability are interchangeable, you could define probability as the probability that a particular event will take place.

To determine probability the  Preliminary geologic  , we obtain,

Step-by-step explanation:

The corrected exact values are cosine (5π/6) = -1/2, cosine (π/12) cannot be simplified further, sine (5π/6) = 1/2, sine (π/12) cannot be simplified further.

Let's correct the calculation of the exact values of the given trigonometric expressions:

1. Cosine (5π/6):

  The angle 5π/6 is in the second quadrant. The reference angle for 5π/6 is π/6. Since the cosine function is negative in the second quadrant, the exact value is -cos(π/6) = -1/2.

2. Cosine (π/12):

  The angle π/12 is not a special angle, so we cannot simplify it further using known exact values.

3. Sine (5π/6):

  The angle 5π/6 is in the second quadrant. The reference angle for 5π/6 is π/6. The sine function is positive in the second quadrant, so the exact value is sin(π/6) = 1/2.

4. Sine (π/12):

  The angle π/12 is not a special angle, so we cannot simplify it further using known exact values.

Therefore, the corrected exact values are:

cosine (5π/6) = -1/2,

cosine (π/12) cannot be simplified further,

sine (5π/6) = 1/2,

sine (π/12) cannot be simplified further.

About 9.1 yards tall.

Step-by-step explanation:

So, we can draw the right triangle shown below:

We want to find h.

Since we know the angle and the side adjacent to the angle and we wan to find the opposite side, we will use the tangent ratio:

\(\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}\)

So:

\(\displaystyle \tan(20)=\frac{h}{25}\)

Therefore:

\(\displaystyle h=25\tan(20)\)

Answer:

GFD = 132.7

Step-by-step explanation:

JIF and GFD are same side interior angles  and when the lines are parallel, same side interior angles are equal

JIF = 132.7  so GFD = 132.7

In the diagram shown, we are given that JIF and GFD are parallel lines. However, these lines are also same side interior angles. This means that they will be equal to each other since they are parallel lines. Remember, parallel lines are coplanar lines that do not intersect.

So if JIF = 132.7°, then GFD also measures 132.7°.
