Answer:
$81
Step-by-step explanation:
The garden is 4 yards = 12 feet by 3 yards = 9 feet. The area of it is the product of these dimensions, ...
(12 ft)(9 ft) = 108 ft²
The cost of fertilizer for that area will be ...
($0.75/ft²)(108 ft²) = $81.00
They will spend $81.00 to fertilize the garden.
Answer:
9
Step-by-step explanation:
9 is the correct answer.
Trapezoidal is involving averageing the heights
the 4 intervals are
[0,4] and [4,7.2] and [7.2,8.6] and [8.6,9]
the area of each trapezoid is (v(t1)+v(t2))/2 times width
for the first interval
the average between 0 and 0.4 is 0.2
the width is 4
4(0.2)=0.8
2nd
average between 0.4 and 1 is 0.7
width is 3.2
3.2 times 0.7=2.24
3rd
average betwen 1.0 and 1.5 is 1.25
width is 1.4
1.4 times 1.25=1.75
4th
average betwen 1.5 and 2 is 1.75
width is 0.4
0.4 times 1.74=0.7
add them all up
0.8+2.24+1.75+0.7=5.49
5.49
t=time
v(t)=speed
so the area under the curve is distance
covered 5.49 meters
Answer:
the answer is 
, and - which is C.
Step-by-step explanation:
well I got that answer by doing this
we have 
= 5
For = f (a) the solutions are x = 
, -
so in this case the solutions are , and -
