Answer:

AC = 10sin 40°

Step-by-step explanation:

From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.

Thus, since we want to find AC;

We know that in trigonometric ratios; opposite/hypotenuse = sin θ

In the diagram, θ = 40° and AB = 10

Thus,

AC/10 = sin 40°

Multiply both sides by 10 to get;

AC = 10sin 40°

Answer:

C

Step-by-step explanation:

Using the sine ratio in the right triangle

To solve the given polynomial addition and subtraction question, combine like terms. The z4 terms combined are -7z4 and the z2 terms are 5z2, resulting in the simplified expression 5z2 - 7z4.

To add or subtract the polynomials 7z2 − 2z4 − 2z2 − 5z4, you'll want to combine like terms. Like terms are terms that have the same variables raised to the same power.

Here, z2 and z4 are like terms, so you can combine them separately.

Starting with the z4 terms:
-2z4 and -5z4 combine to give you -7z4. They both have the same variable z raised to the fourth power, so you just add the coefficients, keeping the exponent the same.

Then, combine the z2 terms:

7z2 and -2z2 combine to give you 5z2.

Similarly, these terms have the same variable z raised to the second power.

Now, putting it all together, you get:

5z2 − 7z4

This is the simplified version of the polynomial after combining like terms.

Area of a rectangle is length x width.

Let the width = x

The length would be x +7. ( 7 inches longer than the width)

Area = 20

Set up the formula:

20 = x * x+7

Simplify the right side:

20 = x^2 + 7x

Subtract 29 from both sides:

X^2 + 7x -20 = 0

Solve using the quadratic equation

X = -b + sqrt(b^2 -4ac) / 2a

X = -7 + sqrt(7^2-4(1)(-20) / 2(1) (exact answer)

X = 2.178908 ( as a decimal)

The width is 2.178907 inches (round as needed)

The length would be 9.178907 inches ( round as needed.)

Depending on how you round, when you multiply them together you get approximately 20 square inches.

Step-by-step explanation:

Step 1:  Find the dimensions

l = 7 + w

Area = 20

Find width

[tex]A = l * w[/tex]

[tex]20 = (7 + w)(w)[/tex]

[tex]20 - 20 = 7w + w^2 - 20[/tex]

[tex]w^2 + 7w - 20 = 0[/tex]

[tex]w=\frac{-(7)\pm\sqrt{(7)^2-5(1)(-20)}}{2(1)}[/tex]

[tex]w = 2.17890...[/tex]

Find length

[tex]l = 7 + w[/tex]

[tex]l = 7 + 2.17890...[/tex]

[tex]l = 9.17890...[/tex]

Answer: [tex]Width = 2.17890..., Length = 9.17890...[/tex]

Answer:

80

Step-by-step explanation:

Following the order of operations (PEMDAS), you would first multiply 10 by 6 to get 60. You would then add 20 to the product to get your answer.

(10 · 6) + 20

60 + 20 = 80

First, let's rearrange the first equation so we can know what y equals to.

So, (x - y = 2) becomes (y = x - 2).

Now, we can plug this into the second equation so we can find x.

6x + 4(x - 2) = 92

6x + 4x - 8 = 92

10x - 8 = 92

10x = 100

x = 10

Now that we know x equals 50, we can plug this into either equations to find y. Let's use the first equation.

10 - y = 2

-y = -8

y = 8

Now, let's check our work by plugging int eh values of x and y for both equations.

First equation:

10 - 8 = 2

Second equation:

6(10) + 4(8) = 92

60 + 32 = 92

So, the values of x and y are correct.

Answer:

180000 m/s

Step-by-step explanation:

The frequency of the wave is 900 Hz.

The wavelength of the wave is 200 m.

The speed of a wave is given as the product of wavelength and frequency. That is:

v = λf

where λ = wavelength

f = frequency

The speed of the wave is therefore:

v = 200 * 900 = 180000 m/s

The speed of the wave is 180000 m/s.

Answer:

For the first one q is 134

And the second one is t is 8.8

Step-by-step explanation:

That is true cause 134 +166 = 300

and, 14.2 = 8.8 - 5.4.

Please Mark brainliest!

For the equations given, the value of q is found to be 134 after subtracting 166 from both sides, and the value of t is calculated as 19.6 by adding 5.4 to both sides.

To solve the first equation, q + 166 = 300, we need to isolate the variable q by subtracting 166 from both sides of the equation:

q + 166 - 166 = 300 - 166

q = 134

So, the value of q is 134.

For the second equation, 14.2 = t - 5.4, we need to isolate the variable t by adding 5.4 to both sides of the equation:

14.2 + 5.4 = t - 5.4 + 5.4

t = 19.6

Thus, the value of t is 19.6.

The statement which best describes the situation correctly is that the golf ball is on the ground at 0 and 6 seconds.

Given that:

Sharon hits a golf ball off the ground.

The function h represents the height of the golf ball, in feet, t seconds after it is hit.

h(t) = -16(t - 3)² + 144, which is a quadratic function.

Since the options contain the time when the ball hits the ground, it is required to find the time when the ball hits the ground.

When the ball is on the ground, the height is 0.

So, h(t) = 0

-16(t - 3)² + 144 = 0

-16(t - 3)² = -144

Divide both sides by -16.

(t - 3)² = 9

Take the square root on both sides.

t - 3 = ±√9

t - 3 = ±3

So, t = 3 + 3 and t = -3 + 3

So, t = 6 and t = 0

Hence, the ball hits the ground when t = 0 and t = 6, which is option B.

Answer:

A) an upper quartile of 56 and a median of 50

Step-by-step explanation:

Hello!

The lower and upper ends "box" from the box and whiskers plot is determined by the first (Q₁) and third (Q₃) quartiles of the data set and the line inside the box marks the median or second quartile of the sample (Q₂)

The length of the whiskers of the diagram is determined by the minimum value (left whisker) and the maximum value (right whisker)

If you observe the graphic:

Q₁= 42

Q₂= 50 (Median)

Q₃= 56

Min= 38

Max= 66

The box is delimited by a lower quartile of 42 and an upper quartile of 56, with a median 50, the least observation is 38 and the highest observation is 66.

The correct choice is A.
