A 20-foot ladder is leaning against a tree. The bottom of the ladder is 12 feet away from the bottom of the tree. Approximately

arsen [322]

Pythagorean theorem is a^2 + b^2 = c^2. the hypotenuse is always the longest, so lets plug in the values.

a^2 + 12^2 = 20^2
if we simplify, we get a^2 + 144 = 400

then subtract 400-144 = 256
then find the sq. root of 256 = 16.

the answer is 16 feet

List all of the integers between -23 and -20.

irinina [24]

That's pretty trivial question... it's the same as if you said you don't know what integers are between 20 and 23...

Video games sold: x Revenue function: R(x) = 60x Cost function: C(x) = 12 + 7x Profit function: P(x) = What is the profit earned

nataly862011 [7]

Answer:

Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.

Step-by-step explanation:

In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x for the sale of x video games

As we know profit = sale price - cost price

Therefore P(x) = R(x) - C(x)

Or P(x) = (R-C)x = 60x - (12+7x)

P(x) = 60x -12 - 7x

P(x) = 53x -12

Now the profit on selling 20 video games will be

P(20) = 53×20 -12 = 1060 -12 = 1048.

Write the standard form of the equation of the circle with center (-5,-7) that passes through the point (7,5).

shutvik [7]

Answer:

(x + 5)² + (y + 7)² = 288

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

The radius is the distance from the centre (- 5, - 7) to the point on the circle (7, 5)

Use the distance formula to calculate r

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, - 7) and (x₂, y₂ ) = (7, 5)

r = $\sqrt{(7+5)^2+(5+7)^2}$ = $\sqrt{12^2+12^2}$ = $\sqrt{288}$

Hence

(x - (- 5))² + (y - (- 7))² = ( $\sqrt{288}$ )², that is

(x + 5)² + (y + 7)² = 288
