Which expression, in exponential form, is equivalent to 26x3y 47z5r3 a) ( 26x3y 47z5r3 )2 b) (26xy) 1 2 (47zr) 1 2 c) 26 1 2 x 3 2 y 1 2 47 1 2 z 5 2 r 3 2 d) 26x 3 2 y 1 2 47z 5 2 r 3 2

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
