Answer:
1.14083...E21
Step-by-step explanation:
The answer to this is A. 650. You find the surface area of the two cubes, then the rectangular prism, then you add them together.<span />
So,
50 + 75 + 16 = 141
150 - 141 = 9

Answer:
This question is pretty simple, half the values given are just to confuse you
notice that we are given a function which gives us the height of the rock at any given time, so if we use that function for t=2 seconds, we will get the height of the rock after 2 seconds
We are given the function:
<em>h(t) = -16t² - 50t + 220</em>
replacing t with 2
<em>h(2) = -16(2)² - 50(2) + 220</em>
<em>h(2) = -16(4) - 100 + 220</em>
<em>h(2) = -64 - 100 + 220</em>
h(2) = 56 feet
Therefore, the height of the rock 2 seconds after throwing is 56 m
Answer:
x = -7, y = 5
Step-by-step explanation:
a) x + 9y = 38, b) 3x + 7y = 14
From a)
x = 38 - 9y ---- (Equation 1)
From b)
{3*(38 - 9y)} + 7y = 14 ----- (From equation 1)
114 - 27y + 7y -14 = 0
100 - 20y = 0
20y = 100
y = 5
From a)
x + (9*5) = 38 (substituting the value of y = 5)
x + 45 = 38
x = 38 - 45
x = -7
Hope, this will help
