Find the annual percentage rate of change for the population of Oregon. In 2000, there were 4.8

MrRa [10]

Answer:

The annual percentage rate of change for the population of Oregon is of 8.125%.

Step-by-step explanation:

Total percentage change:

Change multiplied by 100 and divided by the initial value.

Change: 8.7 - 4.8 = 3.9 million

Initial value: 4.8

Percentage change: 3.9*100/4.8 = 81.25%

Annual percentage rate of change

81.25% during 10 years(from 2000 to 2010).

So, per year

81.25%/10 = 8.125%

The annual percentage rate of change for the population of Oregon is of 8.125%.

Will, Micah and sue went to dinner. Will paid 1/3 of the dinner bill. Micah and sue paid in the ratio of 2:5. If sue paid $6 mor

seraphim [82]

Cost = c
names are abbreviated

w = 1/3c

s = 1/3c + 6

from here i cant go further because i don't know what the numbers mean in the 2:5 ratio. but i will continue if u tell me. for example, could it be the paid cost to the total cost ratio?

What is the volume of the composite figure? Express the

Papessa [141]

Answer:

$V=312\pi\ mm^{3}$

Step-by-step explanation:

we know that

The volume of the composite figure is equal to the volume of a semi-sphere plus the volume of the cone

$V=\frac{4}{6}\pi r^{3} +\frac{1}{3} \pi r^{2} h$

we have

$r=6\ mm$

$h=14\ mm$

substitute

$V=\frac{4}{6}\pi (6)^{3} +\frac{1}{3} \pi (6)^{2} (14)$

$V=144\pi +168\pi$

$V=312\pi\ mm^{3}$

The function g(x) =8(4x) is reflected across the x-axis to create f(x) what is the equation for f(x)

Sveta_85 [38]

Answer:f(x)= -8 (4x) will be the reflected function across x-axis for the function g(x).

Explanation: since we know that the image or reflection of x along x-axis = -x

That is, when we talk about a function's reflection across any axis then we have to replace variable according to that axis. For example if you have a line x=3 in positive x-axis then you can also draw a similar line x=-3 in negative x-axis. so, you can say, x=-3 is the reflection of x=3 along x axis.

Similarly, for an another line y=3, y=-3 is a reflection.

thus in the case of g(x) we can find the reflection across x-axis after replacing x by -x.

we have g(x) =8(4x)

replace x by -x we get g(-x)= 8(4×-x)= 8(-4x)=-8(4x)

so -8(4x) is the reflection of g(x)

but according to the question f(x) is the reflection of g(x) across x-axis.

Thus, f(x)=-8(4x)
