We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.
Answer:
2,160
Step-by-step explanation:
598 + 20 = 618
618 + 987 = 1,605
1,605 + 78 = 1,683
1,683 + 90 = 1,773
1,773 + 87 = 1,860
1,860 + 80 = 1,940
1,940 + 60 = 2,000
2000 + 70 = 2,070
2070 + 90 = 2,160
Answer:
a. 18 b. 119°, 118°
Step-by-step explanation:
a. Given angles are vertical, so they are equal.
6a+11 = 2a+83
6a-2a = 83-11
4a = 72
a = 72/4
a = 18
b. Substituting the value of a in the given angles,
6a+11 = 6*18+11 = 108+11 = 119°
2a+83 = 2*18+83 = 36+83 = 118°
The expression is:
We will use following steps to simplify it:
Step 1:
Use product property of exponents:
That gives us the expression:
Step 2:
Use division property of exponents:
This simplifies the expression:
Step 3:
Writing the square root as power 1/2:
Answer:
The final simplified form in x^n form is :
