Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyra

mina [271]

Answer:

Akira needs 45 square inches of gold foil to cover the chair free including the bottom

Step-by-step explanation:

Total surface = surface area of the base square + area of 4 triangles

Step 1: The surface area of the base square

surface area of the base = surface area of the square = $s^2$

where s is the side length

The the surface area of the base = $3^2$ = 9 square inches

Step 2: The surface area of the side triangles 

The area of the triangle = $\frac{1}{2}\times \text{side length} \times \text{slant height}$

On substituting the values,

The area of the triangle = $\frac{1}{2} \times 3 \times 6$

The area of the triangle = $\frac{18}{2}$

The area of the triangle = 9 square inches

Now the area of 4 triangles = 4 x 9 = 36 square inches

Thus the total surface area = 9 + 36 = 45 square inches

Find the point(s) in which f(x)=e^5-2x and y=6 intercept

Nana76 [90]

Answer:

(1.6, 6)

Step-by-step explanation:

$ln({e}^{5 - 2x} = 6)$

$5 - 2x = ln(6)$

$2x = 5 - ln(6)$

$x = \frac{5 - ln(6) }{2}$

y = 6
