Answer:
129 m/s^2
Step-by-step explanation:
The length of a rectangle is increasing at a rate of 9m/s
dL/dt = 9m/s
The width is increasing at a rate of 7m/s
dw/dt= 7m/s
The formular for solving the area of a rectangle is length × width
Therefore, to calculate how fast the rectangle is increasing we will apply the product rule
dA/dt= L × dw/dt + W × dl/dt
= 12×7 + 5×9
= 84+45
= 129m/s^2
Hence the area of the rectangle is increasing at 129m/s^2
Answer:
320
Step-by-step explanation:
800 = 10
x = 4
800 x 4 = 10 x
3200= 10x
x = 320
Answer:
12 miles
Step-by-step explanation:
Answer:
y= 16
Step-by-step explanation:
For numerator 3 to become 12, the numerator and denominator must be multiplied by 4. 3x4=12 and 4x4=16. this claim is correct since 3/4 = 12/16. Taking this into consideration the value of Y is the same as the value of the second denominator.
