Answer:
Volume = 128
Surface area = 179.2
Step-by-step explanation:
The figure appears to be a square pyramid
The volume of a pyramid can be calculated using the formula : a²(h/3)
where a = base length and h = height
Here the base length appears to be 8 and the height appears to be 6
So we have V = a²(h/3) and a = 8 and h = 6
==> plug in values
V = 8²(6/3)
==> evaluate exponent
V = 64(6/3)
==> divide 6 by 3
V = 64(2)
==> multiply 64 and 2
V = 128
Formula for surface area of a square pyramid is SA = a² + 2al
where a = base length and l = slant height
Looking at the pyramid the slant height appears to be 7.2 and the base length is 8
so we have SA = a² + 2al and a = 8 and l = 7.2
==> plug in values
SA = 8² + 2(8)(7.2)
==> evaluate exponent
SA = 64 + 2(8)(7.2)
==> multiply 2, 8 and 7.2
SA = 64 + 115.2
==> add 64 and 115.2
SA = 179.2
Answer:
None of the sides can be a triangle.

Answer:
x=3
Step-by-step explanation:
The product of the lengths of the segments of one chord equals the product of the segments of the other.
9*5 = x*5x
45 = 5x^2
Divide each side by 5
45/5 = 5x^2/5
9 = x^2
Take the square root of each side
sqrt(9) = sqrt(x^2)
3 =x
Answer:
<em>The products did cost $173.9 in 2010</em>
Step-by-step explanation:
<u>Exponential function</u>
Two variables y and x are related as an exponential function if they comply:
where C is the initial value of F, r is the ratio, and k is a proportional constant.
The situation described in the question is modeled as
Where F is the final value of the cart of groceries in 2010, C = $150 is its value in 2005, r is the yearly rate of increase. n is the number of years
. So
If we set n=5 (from 2005 to 2010):
The products did cost $173.9 in 2010
