Answer:

-4m/s²

Step-by-step explanation:

<u>Given</u><u> </u><u>Equation</u><u> of</u><u> </u><u>velocity</u><u> </u><u>:</u><u>-</u><u> </u>

  • v = 6t² - 4t - 2

<u>Differenciation</u><u> </u><u>of </u><u>first </u><u>order</u><u> </u><u>will </u><u>give </u><u>acclⁿ</u><u> </u><u>:</u><u>-</u><u> </u>

  • v = 6t² - 4t -2
  • dv/dt = d(6t² - 4t -2)/dt
  • dv/dt = 2*6 t¹ - 4*1 t⁰ - 0
  • dv/dt = 12t - 4
  • a = 12t - 4

<u>At </u><u>t </u><u>=</u><u> </u><u>0</u><u> </u><u>,</u>

  • a = 12*0 - 4 m/s²
  • a = -4m/s²

marysya [2.9K]

Answer:

240 square inches

Step-by-step explanation:

1 foot = 12 inches

to convert 4/3 ft to inches, multiply by 12

4/3 × 12 = 16 inches

the area of a square = base × height

base = 16, height = 15

16 × 15 = 240 square inches

Need help please cant understand this probplem
klasskru [66]

Answer:

No solution

Step-by-step explanation:

Distribute the right side of the equation.

This will make it 3/8f+1/2=3/8f - 18

And, since 3/8f plus 1/2 will never equal the same thing as 3/8f minus 18, there are no solutions

Let the width = w.
The length is 6 times the width, so the length is 6w.
The perimeter is 70.
P = 2L + 2W

70 = 2(6w) + 2(w)

70 = 12w + 4w

70 = 14w

5 = w

The width is 5.
The length is 6 times the width, so the length is 6 * 5 = 30

Area of rectangle = LW

A = 5 * 30 = 150
