Answers

Answer:

Step-by-step explanation:

Add 29 to both sides of this equation, obtaining:  x² - 10x + 25.  At this point it becomes obvious that this is a perfect square, the square of x - 5.

Thus, in the first two blanks, write x - 5.

In the second two blanks, write 5 (since 5 is the root corresponding to the factor x - 5).

I NEED HELP QUICKLYDoug got 8 out of 10 questions correct on a math quiz. If each question was worth the same number of points, and the test was worth 50 points total, what was Doug's score?

45 points
8 points
40 points
20 points

Answers

His score was 40 each question was worth 5 points

The answer is 40

50 divided by 10 is 5

Meaning, each question is worth 5 points

8x5 is 40

Therefore, Doug's score was 40

I know it was already answered but still, just incase someone needed an explanation :)

Solve the equation by completing the square. -9n^2+79+=-18n

Answers

Hello,
-9n²+79=-18n
==>9n²-18n-79=0
==>9(n²-2n+1-1)-79=0
==>9(n-1)²-88=0
==>[3(n-1)-2√22][3(n-1)+2√22]=0
==>3(n-1)=2√22 or 3(n-1)=-2√22
==>n-1=2/3*√22 or n-1=-2/3*√22
==>n=1+2/3*√22 or n=1-2/3*√22

A regular square pyramid has a base length of 6 cm. The slant height of the pyramid is 9 cm. What is the surface area of the regular pyramid?a. 90 cm2
b. 120 cm2
c. 144 cm2
d. 252 cm2

Answers

l = 6 cm

By definition, future value is?

Answers

Answer:

Future value  is the value of an item calculated after certain years on a given value at a given certain interest rate.

Future value is always increasing in nature and when future value is decreasing it is know as Depreciate value.

And is calculated using the formula as stated

FV=P(1+(r)/(100) )^n

Where P is the principal amount that is the given amount for which we have t calculate the future value.

r is the rate of interest and it is the rate at which the given principal value is increasing.

n is the time period for which the principal value is kept.
Future value is the value of an asset at a specific date. It measures the nominal future sum of money that a given sum of money is "worth" at a specified time in the future assuming a certain interest rate, or more generally, the rate of return; it is the present value multiplied by the accumulation function.
