Answer:

C = 7.72 ~ 7.7

Step-by-step explanation:

So when you solve this equetion you must 1st find x then c

we can find x by using cos(60)

cos(60) = x/14

x = cos(60) × 14

x = 1/2 ×14

x = 7

so after we find x we are going to solve c by using cos (25)

cos (25) = X/C = 7/c

cos(25) × C = 7

C = 7/cos (25)

C = 7.72 ~ 7.7

so the solution is 7.7

The possible values of the arc AE are 175 and 185 degrees

From the question, we have the following parameters that can be used in our computation:

The circle R

Where the measures of  the arcs are

AB = 60

BC = 25

CD = 70

DE = 20

Add the measures of the above arcs

So, we have

AE = 60 + 25 + 70 + 20

Evaluate

AE = 175

Another possible value is

AE = 360 - minor AE

AE = 360 - 175

Evaluate

AE = 185

Hence, the possible values of the arc AE are 175 and 185 degrees

Step-by-step explanation:

A system of linear equations for line h and j are y = -3x/4 - 5 and y = -5x/4 + 1 respectively.

An equation for the exponential function graphed is \(f(x)=\frac{1}{3}^{x}\)

First of all, we would determine the slope of line h as follows;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (1 - 7)/(-8 + 16)

Slope (m) = -6/8

Slope (m) of line h = -3/4.

At data point (-8, 1) and a slope of -3/4, a linear equation in slope-intercept form for line h can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1 = -3/4(x + 8)

y - 1 = -3x/4 - 6

y = -3x/4 - 5

At data point (-4, 6) and a slope of -5/4, a linear equation in slope-intercept form for line j can be calculated by using the point-slope form as follows:

y - 6 = -5/4(x + 4)

y - 6 = -5x/4 - 5

y = -5x/4 + 1

In Mathematics, an exponential function can be modeled by using the following mathematical equation:

\(f(x) = a(b)^x\)

Since this exponential function passes through the points (0, 1) and (-1, 3), we have:

1 = ab⁰

1 = a

3 = a(b)⁻¹

3 = 1 × (b)⁻¹

3 = 1/b

b = 1/3

Therefore, the graphed exponential function is given by;

\(f(x) = a(b)^x\\\\f(x) = 3^{-x}\\\\f(x)=\frac{1}{3}^{x}\)

The wind has a magnitude of approximately 20.25 km/h and is blowing in a direction approximately 56.31° east of south. Magnitude is the hypotenuse of a right triangle with westerly and southerly components.

To find the magnitude and direction of the wind with a westerly component of 11 km/h and a southerly component of 17 km/h, we can use the Pythagorean theorem and trigonometry.

The magnitude of the wind is given by the hypotenuse of a right triangle with legs 11 km/h and 17 km/h. Using the Pythagorean theorem, we get:

magnitude = \(\sqrt{(11^2 + 17^2)} \approx 20.25 \;km/h\)

To find the direction of the wind, we can use trigonometry. The angle θ between the wind direction and the east direction can be found using the inverse tangent function:

\(tan(\theta)\) = opposite/adjacent = 17/11

\(\theta = atan(17/11) \approx 56.31^{\circ}\)

Therefore, the wind has a magnitude of approximately 20.25 km/h and is blowing in a direction approximately 56.31° east of south.

In summary, to find the magnitude and direction of wind with given westerly and southerly components, we can use the Pythagorean theorem and trigonometry.

The magnitude is given by the hypotenuse of a right triangle with legs equal to the westerly and southerly components, while the direction is given by the angle between the wind direction and the east direction, which can be found using the inverse tangent function.

The graph of function is shown.

And, the function y = 2 (3)^x has no horizontal or vertical asymptotes.

We have to given that,

The function is,

⇒ f (x) = 2 (3)ˣ

Now,

We know that, If the degree of the numerator is less than the degree of the denominator, then the horizontal asymptote is y = 0.

If the degree of the numerator is greater than or equal to the degree of the denominator, then there is no horizontal asymptote.

Since the function y = 2 (3)^x has no denominator, there is no horizontal asymptote.

We know that, When the denominator becomes zero for some value of x, then there is a vertical asymptote at that value of x.

Since there is no denominator in the function y = 2 (3)^x, there is no vertical asymptote.

Therefore, the function y = 2 (3)^x has no horizontal or vertical asymptotes.

Answer: 29 1/4

Step-by-step explanation:

Multiply and simplify to 29 1/4

Answer:

12

Step-by-step explanation:

Ella has two 8 feet long boards, so in total, she has 16 feet of the boards.

Convert these 16 feet to inches. There are 12 inches in a foot, so multiply 16 by 12:

16(12)

= 192

So, there are 192 inches in the boards. Divide this by 15 to see how many 15 inch pieces she can cut:

192/15

= 12.8

We can only have a whole number answer, because the boards need to be a full 15 inches. So, round this down:

= 12

Ella can cut twelve 15 inch pieces.

Researchers try to gain insight into the characteristics of a sample population by examining a sample of the population.

A sample is a subset of individuals or units taken from a larger population. Researchers use sampling methods to select a representative group of individuals from the population they are interested in studying. By studying the sample, researchers can make inferences and draw conclusions about the characteristics, behaviors, or trends that may exist within the entire population.

The goal of sampling is to obtain a sample that accurately represents the population in terms of its relevant characteristics. Researchers carefully select their samples to ensure that they are representative and minimize bias. This allows them to generalize the findings from the sample to the larger population with a certain level of confidence.

By examining a sample, researchers can collect data, analyze patterns, and draw conclusions about the population as a whole. This approach is more feasible and practical than attempting to study the entire population, especially when the population is large or geographically dispersed.

Therefore, researchers use samples to gain insight into the characteristics of a population, making option d. "Sample" the correct answer.

Answer:

3:30 is the answer

For this case we have the following kinematic equation that models the problem:

h (t) = (1/2) * (- 9.8) * t ^ 2 + 12 * t + 2

Rewriting we have:

h (t) = -4.9 * t ^ 2 + 12 * t + 2

When the ball hits the ground we have:

-4.9 * t ^ 2 + 12 * t + 2 = 0

Solving the polynomial we have:

t1 = -0.16

t2 = 2.61

We ignore the negative root because it is time.
