What is the answer to this ?
harina [27]

Answer:

The answer is option 1.

Step-by-step explanation:

In order to solve x, you have to make x the subject, by multiplying each sides by 5, to get rid of 5 on the left side.

\frac{x}{5}  = 8

\frac{x}{5}  \times 5 = 8 \times 5

x = 40

Let f(x)=ln(3x)+2.5 .
Cerrena [4.2K]
For this case what we should do is evaluate the function in each of the points from 2 to 7 and then find the average.
 We have then:
 f (x) = ln (3x) +2.5.
 f (2) = ln (3 * 2) + 2.5 = 4.291759469
 f (3) = ln (3 * 3) + 2.5 = 4.697224577
 f (4) = ln (3 * 4) + 2.5 = 4.98490665
 f (5) = ln (3 * 5) + 2.5 = 5.208050201
 f (6) = ln (3 * 6) + 2.5 = 5.390371758
 f (7) = ln (3 * 7) + 2.5 = 5.544522438
 Then the average is:
 Average = (4.291759469 + 4.697224577 + 4.98490665 + 5.208050201 + 5.390371758 + 5.544522438) / (6) = 5.019472516
 nearest hundredth
 5.02
 Answer:
 the average rate of change of f (x) from 2 to 7 is  5.02

A circle with circumference 20 has an arc with 72 degree central angle what is length of the arc
Debora [2.8K]

Answer:

<h2>4</h2>

Step-by-step explanation:

<em>Look at the picture.</em>

<em />

<em>At the beginning we have to calculate what part of the angle 360° is the given angle 75°.</em>

<em />\dfrac{75}{360}=75:360=0.2<em />

<em>The same part of the circumference of the circle is the arc defined by this central angle.</em>

The circumference <em>C = 20</em>.

Therefore

x=0.2\cdot20=4
