Answer:
(s*t)(-7) = 987
Step-by-step explanation:
s(x) = 2 - x²
t(x) = 3x
To find (s*t)(x), multiply s(x) and t(x).
(s*t)(x) = (2 - x²)(3x)
(s*t)(x) = 6x - 3x³
Now that you have (s*t)(x), plug -7 in.
(s*t)(-7) = 6(-7) - 3(-7)³
(s*t)(-7) = 6(-7) - 3(-343)
(s*t)(-7) = -42 + 1029
(s*t)(-7) = 987
Answer:
The average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
Step-by-step explanation:
The service rate was given as $11, $84, $94 and $103.
The average service rate = 
= 
= 
= 73
Their average service rate is $73.
But comparing the average service rate to their given service rates, the average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).

Step-by-step explanation:
The area of the part with grass is 20 square meters.
Step-by-step explanation:
Step 1:
We can find the area of the grass by subtracting the area occupied by the sand from the area of the entire park.
The area of a rectangle is obtained by multiplying the length with the width of the rectangle.
The area of the part with grass = The area of the entire park - The area of the part with sand.
Step 2:
The entire park has a length of 6 m and a width of 4 m.
The area of the entire park
square meters.
The area of the part with sand has a length of 2 m and a width of 2 m. It is actually a square.
The area of a square is the square of the side length.
The area of the part with sand
square meters.
Step 3:
The area of the part with grass = The area of the entire park - The area of the part with sand.
The area of the part with grass
.
The area of the part with grass is 20 square meters.
