Rhianna is building a rectangular pyramid for a science fair project. The net of the pyramid and its dimensions are shown in the diagram
Rhianna will cover the lateral surface of the pyramid with foil.
What is the area Rhianna will
cover with foil in square
centimeters?
5.2 cm
141.12 cm?
70.56 cm?
5 cm
74.28 cm
7.8 cm
6 cm
109.56 cm​

1 is b and 2 is d

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
