Hi there

This is a smart question, so let me show you the trick of it.

176 feet per second
but we dont know per minute

We know that 60 seconds = 1 minute
with that information we can solve it

If 176 .......... 1 second
x .............. 60 second
x = 176 * 60
x= 10560

He is falling 10560 feet per minute

Answer:

<DAB = 120

Step-by-step explanation:

7)

<DAB = ?

<DAB + <DCB = 180

so

16x + 8 + 8x + 4 = 180

24x + 12 = 180

24x = 168

x = 7

<DAB = 16(7) + 8 = 120

Analysis of an accident scene indicates a car was traveling at a velocity of 69.5 mph (31.1 m/s) along the positive x-axis at th

STatiana [176]

We can find the acceleration via

${v_f}^2-{v_i}^2=2a\Delta x$

We have

$\left(5.20\dfrac{\rm m}{\rm s}\right)^2-\left(31.1\dfrac{\rm m}{\rm s}\right)^2=2a(115\,\mathrm m)$

$\implies\boxed{a=-4.09\dfrac{\rm m}{\mathrm s^2}}$

Then by definition of average acceleration,

$a_{\rm ave}=\dfrac{v_f-v_i}t$

so that

$-4.09\dfrac{\rm m}{\mathrm s^2}=\dfrac{5.20\frac{\rm m}{\rm s}-31.1\frac{\rm m}{\rm s}}t$

$\implies\boxed{t=6.33\,\mathrm s}$

We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is

$v_{\rm ave}=\dfrac{x_f-x_i}t=\dfrac{v_f+v_i}2$

Then

$\dfrac{115\,\rm m}t=\dfrac{5.20\frac{\rm m}{\rm s}+31.1\frac{\rm m}{\rm s}}2$

$\implies\boxed{t=6.33\,\mathrm s}$

Answer:

50/18 or 2.77

Step-by-step explanation:

So first u have to make the 3 1/3 and 1 1/5 into improper fractions.

Then, you can do the keep, change, flip thing and then u get 10/3 x 5/6 to get 50/18

A company determined that the marginal cost, C' (x )of producing the xth unit of a product is given by C' (x )= x^3- 6x. Find t

Rashid [163]

Answer:

$C(x) = \frac{x^4}{4}-3x^2+3,000$

Step-by-step explanation:

The marginal cost function, C'(x), is the derivate of the cost function, C(x).

Therefore, we can obtain the cost function by finding the integral of the marginal cost function:

$C(x) = \int\ {C'(x)} \, dx \\C(x) = \int\ {(x^3-6x)} \, dx \\C(x) = \frac{1}{4} x^4-3x^2+a$

Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:

$C(x) = \frac{x^4}{4}-3x^2+3,000$
