Remark

Usually this is written in very simple terms. You could do it as a proportion, but it might be easier to see if you used Newton's formula twice.

Formula

F = m * a

m = mass, F = force, a = accelerationn

Givens

F1 = 70 N

a1 = 6.5 m/s^2

m = ?

F2 = ??

m = ?

a2 = 8 m/s^2

Step One

Solve for m

F1 = m * a1 Substitute the values

70 = m * 6.5 Divide by 6.5

70/6.5 = m

10.77 kg = m

Step Two

Solve for F2

m = 10.77 kg

a = 8

F2 = ??

F2 = m * a2

F2 = 10.77 * 8

F2 = 86.154

Answer: C rounded to the nearest 1/100

9/2 mph. You would need to multiply both by six to get exact mph, and three fourths times six is 18/4=9/2=4.5 mph

describe the transformations that produce the graph of g(x)=1/2(x-4)^3+5 from the graph of the parent function f(x)=x^3. Give th

SSSSS [86.1K]

We have been given a parent function $f(x)=x^{3}$ and we need to transform this function into $g(x)=\frac{1}{2}(x-4)^{3}+5$ .

We will be required to use three transformations to obtain the required function from $f(x)=x^{3}$ .

First transformation would be to shift the graph to the right by 4 units. Upon using this transformation, the function will change to $g(x)=(x-4)^{3}$ .

Second transformation would be to compress the graph vertically by half. Upon using the second transformation, the new function becomes $g(x)=\frac{1}{2}(x-4)^{3}$ .

Third transformation would be to shift the graph upwards by 5 units. Upon using this last transformation, we get the new function as $g(x)=\frac{1}{2}(x-4)^{3}+5$ .

Mr gerhring has a 3/4 pound bag of flour to use for 6 cakes. how much flour is used for EACH cake?? I need work plz and thank u.

VMariaS [17]

The answer is B. You can find this by turning 3/4 into a decimal, which is .75. You can then divide .75 by 6 to get 0.125 (which is the decimal form of 1/8).
