Y = -4x + 3
Because, it has the same slope (-4) as the slope of y = -4x + 8

Answer:

pi/2 units to the left

Step-by-step explanation:

the formula is y = cos(x-b) so when b is negative, the formula will show a plus sign because minus negative is adding. this means the graph is shifted -pi/2 to the right which is really pi/2 to the left

A telephone pole is installed so that 25 feet of the pole are above ground level. A stabilizing cable is anchored to the ground

Tasya [4]

$\huge\boxed{244\ \text{inches}}$

This problem can be solved using the Pythagorean Theorem.

<em>Note: the height of the telephone pole is unnecessary information.</em>

Convert the measurement in feet to inches.

$20*12=240$

The length from the base of the pole to the anchor point on the ground is $44$ inches. The distance from the base of the pole to the anchor point on the pole is $240$ inches.

These are the two legs of a right triangle. The length of the stabilizing cable is the hypotenuse of the right triangle.

The Pythagorean Theorem is:

$a^2+b^2=c^2$

In this formula, $a$ and $b$ are the legs and $c$ is the hypotenuse.

Plug in the known values.

$44^2+240^2=c^2$

Swap the sides of the equation.

$c^2=44^2+240^2$

Evaluate the powers.

$c^2=1936+57600$

Simplify using addition.

$c^2=59536$

Take the square root of both sides.

$c=\pm 244$

Separate the solutions.

$c=244\\c=-244$

Length and distance cannot be negative, so remove the negative solution.

$c=\boxed{244}$

8 x 300 = 2400
9 x 270 = 2430
10 x 240 = 2400
11 x 210 = 2310

A parallelogram has a perimeter of 50.12 inches. The two longer sides of the parallelogram are each 16.14 inches. Write an equat

icang [17]

Answer:

<u>The equation to find the length of each of the shorter sides of the parallelogram is 2x + 32.28 = 50.12 and the value of x is 8.92 inches.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Perimeter of the parallelogram = 50.12 inches

Length of the longer sides = 16.14 inches

Length of the shorter sides = x

2. Write an equation to find the length x of each of the shorter sides.

Perimeter of the parallelogram = 2 * Length of the longer sides + 2 * Length of the shorter sides

50.12 = 2 * 16.14 + 2 *x

2x + 32.28 = 50.12

2x = 50.12 - 32.28

2x = 17.84

x = 17.84/2

<u>x = 8.92</u>

<u>The equation to find the length of each of the shorter sides of the parallelogram is 2x + 32.28 = 50.12 and the value of x is 8.92 inches.</u>
