Because of the unexpected cold weather,the cost of tomatoes increased 50 percent in one month.If the cost after the increase was
Tasya [4]
A 50% increase is just taking the original amount and adding half of that towards the amount.

Example : 50% of 100 is 50 so a 50% increase to 100 would be 150

a formula for this would be X + (1/2×X) = Y

in your case we're working backwards with the known being 60

We can just plug in reasonable values for X until we get 60

50% of 40 is 20

40 + 20 = 60

so the original amount was 40

What is the rate of change for f(x)=-2cos4x-3 on the interval from x=0 to x=pi over 4
Anestetic [448]

Answer:

\frac{16}{\pi}

Step-by-step explanation:

The average rate of a function f on interval x=a to x=b is:

\frac{f(b)-f(a)}{b-a}.

a=0 and b=\frac{\pi}{4} here for this problem where f(x)=-2\cos(4x)-3.

So we will need to evaluate f for x=0 \text{ and } b=\frac{\pi}{4}.

To find f(0) we will replace x in f(x)=-2\cos(4x)-3 with 0:

f(0)=-2\cos(4(0))-3

f(0)=-2\cos(0)-3

f(0)=-2(1)-3

f(0)=-2-3

f(0)=-5

To find f(\frac{\pi}{4}) we will replace x in f(x)=-2\cos(4x)-3 with \frac{\pi}{4}:

f(\frac{\pi}{4})=-2\cos(4(\frac{\pi}{4}))-3

f(\frac{\pi}{4})=-2\cos(\pi)-3

f(\frac{\pi}{4})=-2(-1)-3

f(\frac{\pi}{4})=2-3

f(\frac{\pi}{4})=-1

So now we need to compute the change in f over the change in x:

\frac{-1-(-5)}{\frac{\pi}{4}-0}

\frac{-1+5}{\frac{\pi}{4}}

Dividing by \frac{\pi}{4} is the same as multiplying by \frac{4}{\pi}:

(-1+5)\cdot \frac{4}{\pi}

4 \cdot \frac{4}{\pi}

\frac{16}{\pi}
