Answer:
Help what?
Step-by-step explanation:
Zeros are -2 and -8
Functions are =-2 and -8
(X + 2) (X + 8)
X to the power of 2 + 8x + 2x+16
= x to the power of 2 + 10x + 16
<em><u>Complete Question:</u></em>
You can model the population of a certain city between 1955-2000 by the radical function
P(x) = 55,000 sqrt x-1945
Using this model, in which year was the population of that city 275,000?
<em><u>Answer:</u></em>
In 1970 population of that city is 275,000
<em><u>Solution:</u></em>
Given that,
<em><u>You can model the population of a certain city between 1955-2000 by the radical function
:</u></em>

To find: year in which was the population of that city 275,000
Therefore,
x = ?
P(x) = 275000
Thus we get,

Thus, in 1970 population of that city is 275,000
It would be 10^-7.
When you have a negative number in scientific notation, you count a whole zero and start counting behind the decimal point because a negative number is less than 0. So, it cannot have a value over 0. Though if it was after the decimal, it would be the positive answer because a positive number is higher than 0.
An example would be:
10^-3=0.001
10^3=1000
Answer:
A) 
Step-by-step explanation:
The volume of a triangular prism can be found using the formula
(1)
where
A is the area of the base
h is the height of the prism
Here, the base is a right triangle; the area of a triangle is

where
b is the base
h' is the height of the triangle
Here, the triangle has the two sides equal, and it is a right triangle, so we have

So the area of the base is

We also know that the height of the prism is equal to the leg length of the base, so

Therefore substituting into (1) we find:
