The horsepower , H(s), required for a racecar to overcome wind resistance is given by the function : H(s) = 0.003s^2+0.07s-0.027
mote1985 [20]
Average rate of change = [H(100) - H(80)] / (100 - 80)
H(100) = 0.003(100)^2 + 0.07(100) - 0.027 = 0.003(10000) + 0.07(100) - 0.027 = 30 + 7 - 0.027 = 36.973

H(80) = 0.003(80)^2 + 0.07(80) - 0.027 = 0.003(6400) + 0.07(80) - 0.027 = 19.2 + 5.6 - 0.027 = 24.773

Average rate of change = (36.973 - 24.773)/(100 - 80) = 12.2/20 = 0.61

If a = − 65 and b = 8, the product of a x b models which rule for multiplying integers? What is the product?
DedPeter [7]

Given, a = -65 and b = 8.

We have to find multiplication of them.

a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means (+)(-) = -.

So (a)(b) = (-65)(8)

= (-)(+)(65)(8) = - (65)(8) = -520

So we have got the required product.

Multiplication of a and b = -520.

The correct option is option C.

A bag contains 10 tiles with the letters A, B, C, D, E, F, G, H, I, and J. Five tiles are chosen, one at a time, and placed in a
lora16 [44]
I assume in this item, we are to find at which step is the mistake done for the calculation of the unknown probability. 

For the possible number of arrangement of letter, n(S), the basic principles of counting should be used.
                       = 10 x 9 x 8 x 7 x 6 = 30,240

This is similar as to what was done in Meghan's work.

For the five tiles to spell out FACED, there is only one (1) possibility.

Therefore, the probability should be equal to 1/30,240 instead of the 1/252 which was presented in the steps above.

Find the solution to the initial value problem (1 + x^{5}) y' + 5 x^{4} y = 5 x^{8}
natali 33 [55]
(1+x^5)y'+5x^4y=5x^8
\bigg((1+x^5)y\bigg)'=5x^8
(1+x^5)y=5\displaystyle\int x^8\,\mathrm dx
(1+x^5)y=\dfrac59x^9+C
y=\dfrac{5x^9+C}{9(1+x^5)}

Does 2 1/4-6/7=1 3/4
dimulka [17.4K]

Answer: No, it would be 2/5.


Step-by-step explanation: 2 1/4 - 6/7 is equal to about 1.4 when rounded to the nearest tenth. 1.4 as a fraction would be 4/10. 4/10 is simplified to 2/5 by dividing each number by 2.
