The cloth acts as insulation it doesn't matter the colour . And as to Black cloth attracting Heat this is only partially true if you put a black cloth in the room with no windows and the temperature of the room was 70° the cloth will not get any hotter black cloth absorbs infrared energy this makes it feel warmer

What is the slope of the line containing the points (5,6) and (9,13)
Nataly_w [17]
You would subtract the y intercepts then the x intercepts. Subtract 13-6 then divide it by 9-6. That gets you a slope of 7 over 3

F(x) = x² + 5x-1 is shifted 3 units right. The result is g(x). What is g(x)?
CaHeK987 [17]

Answer:

D

Step-by-step explanation:

When a function is being shifted to the left, all x values will be added by y units shifted. (The constant that comes with x is excluded, eg. 3x shifted by 2 units left, becomes 3(x+2) and not 3x+2.)

Likewise, when a function is being shifted to the right, all x values will be subtracted by y units shifted. (Constant rules applies as well.)

Given f(x) is shifted 3 units right,

the new function, g(x) becomes:

g(x) = {(x - 3)}^{2}  + 5(x - 3) - 1

Therefore the answer is D in this case.

Triangle RST has sides measuring 22 inches and 13 inches and a perimeter of 50 inches. What is the area of triangle RST? Round t
VladimirAG [237]

Using the Heron's formula, the area of the triangle is: D. 95 square inches.

<h3>What is the Heron's Formula?</h3>

Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.

Given the following:

s = semi-perimeter = 1/2(50) = 25 in.

a = length of side a = 22 in.

b = length of side b = 13 in.

c = length of side c = 50 - 22 - 13 = 15 in.

Plug in the values

Area = √[25(25 - 22)(25 - 13)(25 - 15)]

Area = √[25(3)(12)(10)]

Area ≈ 95 square inches.
