Answer:  y=3x -10

slope : 3 y-int : -10

Step-by-step explanation: I believe this is the answer

The measure of angle AXY based on the information will be A. 70°.

It should be noted that the value of a right angle is equal to 90°.

In this case, we will add the angles that are given and equate them to 90°. This will be:

6x + 40 + 10 + 2x = 90°

8x + 50 = 90°

Collect like terms

8x = 90° - 50°

8x = 40°

Divide

x = 40° / 8

x = 5°

Therefore, the value of angle AXY will be:

= 6x + 40

where x = 5.

= 6(5) + 40

= 30 + 40

= 70°

Answer:

y = mx + b

Step-by-step explanation:

so you first put the points on the graph and connect them with a slanted line.

Next, for your equation start of with y =

then, your going to find your slope, after you find it put it in front of x (slope x) (Ex; if the slope was 3 then it would look like this 3x)

finally you write + and the y intercept (at which point the line goes through the y axis)

the equation together should look like y = slope x + y intercept

Answer:

Step-by-step explanation:

To estimate the required sample size for estimating the true proportion of Americans who support gun control in 2018 with a 95% confidence level and a margin of error of 0.36, we need to use the formula:

n = (Z^2 * p * (1 - p)) / E^2

Where:

n = required sample size

Z = Z-score corresponding to the desired confidence level (for 95% confidence level, Z ≈ 1.96)

p = estimated proportion (since we have no prior information, we can use p = 0.5, which gives the maximum sample size required)

E = margin of error

Substituting the values into the formula:

n = (1.96^2 * 0.5 * (1 - 0.5)) / 0.36^2

n = (3.8416 * 0.25) / 0.1296

n ≈ 9.6042 / 0.1296

n ≈ 74.0842

Rounding up to the nearest whole number, the required sample size is approximately 75. Therefore, you would need to survey at least 75 randomly selected Americans to estimate the true proportion of Americans who support gun control in 2018 with a 95% confidence level and a margin of error of 0.36.

The complete solution is:

\(\int∫sin²(2x) dx = (\frac{3}{4)}x - (\frac{1}{4})sin(2x) + C\)

We can use the identity: sin(2x) = 2sin(x)cos(x) to simplify the integrand.

\(sin^2(2x) = (sin(2x))^2\)

\(= (2sin(x)cos(x))^2\)

\(= 4sin^2(x)cos^2(x)\)

Therefore, we have:

\(\int∫sin²(2x) dx =\int ∫4sin^2(x)cos^2(x) dx\)

Next, we can use the identity: \(2cos^2(x) - 1 = cos(2x)\) to express the integrand solely in terms of sine:

\(4sin^2(x)cos^2(x)\)

= \(4sin^2(x)(1 - sin^2(x))\)

\(= 4sin^2(x) - 4sin^4(x)\)

\(= 4sin^2(x) - (1 - cos(2x))^2 / 4\)

\(= 4sin^2(x) - (1/4) + (1/2)cos(2x) - (1/4)cos^2(2x)\)

Now we can integrate term by term:

\(\int∫sin²(2x) dx = \int∫4sin^2(x)cos^2(x) dx\)

\(= 4\int∫sin^2(x)dx - \int∫(1/4)dx + \int∫(1/2)cos(2x)dx - \int∫(1/4)cos^2(2x)dx\)

We can use the identity: sin^2(x) = (1/2) - (1/2)cos(2x) to evaluate the first integral:

\(\int∫sin^2(x)dx = \int∫(1/2) - (1/2)cos(2x) dx\)

= (1/2)x - (1/4)sin(2x) + C1

The next two integrals are straightforward:

\(\int∫(1/4)dx = (1/4)x + C2\)

\(\int∫(1/2)cos(2x)dx = (1/4)sin(2x) + C3\)

For the last integral, we can use the identity: \(cos^2(2x)\) = (1/2) + (1/2)cos(4x) to simplify:

\(\int∫cos^2(2x)dx =\int ∫(1/2) + (1/2)cos(4x)dx\)

=\((1/2)x + (1/8)sin(4x) + C4\)

Putting all the pieces together, we get:

\(\int∫sin²(2x) dx = 4\int∫sin^2(x)dx - \int∫(\frac{1}{(4)}dx + \int∫(\frac{1}{(2)}cos(2x)dx - \int∫(\frac{1}{4})cos^2(2x)dx\)

= 2x - (1/2)sin(2x) + (1/4)sin(2x) + (1/8)sin(4x) - (1/4)x - (1/8)sin(4x) + C

= 2x - (1/4)x - (1/2)sin(2x) + (1/4)sin(2x)

= (3/4)x - (1/4)sin(2x) + C

Therefore, the complete solution is:

\(\int∫sin²(2x) dx = (\frac{3}{4)}x - (\frac{1}{4})sin(2x) + C\)

Answer:

Explanation:

Generally, the slope-intercept form of the equation of a line is given as;

where m = the slope of the line

b = y-intercept of the line

From the question, we're told that the required line will pass through the origin and (3, 2), so we can find our slope(m) of the line using the given coordinates x1 = 0, y1 = 0, x2 = 3, and y2 = 2;

So the slope(m) of the line is 2/3.

Since we're told that the line will pass through the origin, it means that the y-intercept (b) = 0.

Since the gragh will be shaded above the dashed line, it means that the inequality will have a greater than sign(>).

We're told that the line will be dashed, it means that the function have only the greater than sign(>) without the equal to sign(=).

The angles and length of the right triangle are as follows:

WX = 10√141 units

m∠X  = 30°

m∠V = 60°

A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a right angle triangle is 180 degrees.

Trigonometric ratios can be used to find the side and angles of the right triangle as follows;

Therefore,

Using Pythagoras's theorem,

WX² = (20√47)² - (10√47)²

WX² = 400(47) - 100(47)

WX² = 18800 - 4700

WX = √14100

WX = 10√141

Let's find the angles

sin m∠X  = opposite / hypotenuse

sin m∠X  = 10√47 / 20√47

sin m∠X  = 1 / 2

m∠X  = sin⁻¹ 0.5

m∠X  = 30 degrees

Therefore,

m∠V = 180 - 90 - 30

m∠V = 60 degrees

The cost of the steak is calculated by multiplying the cost per pound by the weight in pounds. As the cost per pound is $10.25 and the weight is 1.2 pounds. The result is $12.30.

The total cost of 1.2 pounds of steak can be calculated by multiplying the cost per pound by the weight in pounds. In this case, the cost per pound is given as $10.25.

To find the total cost, we need to multiply the cost per pound by the weight in pounds:

$10.25/pound * 1.2 pounds = $<<10.25*1.2=12.3>>12.30

Therefore, the total cost of 1.2 pounds of steak will be $12.30.

Please note that the cost of the steak is calculated by multiplying the cost per pound by the weight in pounds. In this case, the cost per pound is $10.25 and the weight is 1.2 pounds. The result is $12.30.

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg

What is a unit amount in math?

When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio

1 k + 6.6 k = 617.3

Where “k” is a constant value, a multiplier.

Solving for k:

7.8 k = 617.3

k = 617.3 /7.8  

k= 79.17

So:

Amount of onion used:

1 (79.17) = 79.17 kg

Amount of grilled steak used:

6.6 (79.17) = 538.356 kg

Sequences in which the difference between succeeding terms is constant are known as arithmetic progressions.
