Answer:

$-6v^7$

$p^6$

Step-by-step explanation:

$-1v^3 \times -2v^2 \times -3v^2$

$-6v^{3+2+2}$

$-6v^7$

$1/2p^2 \times p^3 \times 2p$

$1/2p^2 \times 1p^3 \times 2p$

$1p^{2+3+1}$

$1p^6$

A circle has a circumference of 6. It has an arc of length 17/3. What is the central angle of the arc, in degrees?

zepelin [54]

Answer:

340 degrees

Step-by-step explanation:

So the key thing here is to notice that we are given the circumference which will allow us to find a value for the radius of the circle and hence the angle subtended by the arc (the central angle).

So the circumference of a circle = 2pi(r)

This means:

6 = 2pi(r)

Which means that

r = 6/2pi or r = 3/pi

Now we can use this value of r to find our angle in conjunction with the value of the arc length. So:

Arc length is defined by: length = θr

Where θ is our angle value.

So lets plug in:

$\frac{17}{3} = (angle)\frac{3}{\pi }$

Multiply by pi to get:

$\frac{17\pi }{3} = 3(angle)$

Divide by 3 to get that:

θ = 17pi/9

So if we convert that from radians to degrees we get 340 degrees.

In 2015, the population of a district was 10,600. With an annual growth rate of approximately 4%, what will the population be in

Murljashka [212]

Answer:

$19,090\ people$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$y=a(1+r)^x$

where

y is the population

x is the time in years since year 2015

a is the initial value

r is the rate of change

we have

$a=10,600\\r=4\%=4/100=0.04$

substitute

$y=10,600(1+0.04)^x$

$y=10,600(1.04)^x$

In the year 2040 the value of x is equal to

$x=2040-2015=25\ years$

substitute

$y=10,600(1.04)^{15} =19,090\ people$

Solve 8x+c= k for x.

Anon25 [30]

Answer:

x = (k-c)/8

Step-by-step explanation:

8x+c= k

Subtract c from each side

8x+c-c= k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x = (k-c)/8
