We know that
[surface area <span>of the ramp]=10*16+8*16+6*16+2*[6*8/2]
</span>[surface area of the ramp]=160+128+96+48-----> 432 ft²
the answer Part a) is
the surface area of the ramp is 432 ft²
if 1 ft² is sold for--------------------> $3
432 ft²-------------------> x
x=432*3-----> x=$1296
the answer Part b) is
$1296

Answer:
DJ = 48
Step-by-step explanation:
In triangle CDE, point J is the centroid.
Length of median DH = 72
By the property of the centroid of a triangle,
"Centroid of a triangle divides the medians in the ratio of 2 : 1"
By this property, length of DJ =
=
= 48 units
Therefore, length of DJ = 48 units
If g(x) is a reflection of f(x) over the x axis, then g(x) = -1*f(x), which can be shortened to g(x) = -f(x). We stick a negative outside the entire f(x) function to flip the signs of each y coordinate. For example, if the point (1,2) was on f(x), then (1,-2) is on g(x).
So f(x) = 5(0.8)^x turns into g(x) = -5(0.8)^x
Answer: Choice B
Answer:
Center: (-5,3)
Radius: 4
Step-by-step explanation:
Let's first start with the equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
The center is (-h, -k)
Which is: (-5,3)
Lastly our radius is
Radius = 4
Hope this helps!
