Choice 1. He did not square 40, he just multiplied by 2.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse measures c cm while the other sides are 40 cm and 9 cm each.
Step 2:
According to the Pythagorean theorem,




This is the correct solution to the given problem. Hans did not square 40, he just multiplied by 2. Which is the first option.
Answer:
-28
Step-by-step explanation:
Answer:
1/ 9^5
Step-by-step explanation:
When dividing exponents with the same base, subtract the exponents
9^2 / 9^7
9 ^ (2-7)
9^ -5
We know that a^ -b = 1/ a^b
1/ 9^5
Percentage of depreciation of the car that Marie bought = 15%
Present value of the car = 13000
Let us assume that the value of the car at the time of buying = x
So
The percentage valuation of the car now = (100 - 15) percent
= 85 percent
Then
(85/100) * x = 13000
85x = 13000 * 100
85x = 1300000
x = 1300000/85
= 15294.12
So the actual cost of the car is 15294.12. I hope the procedure is clear enough for you to understand.
I believe the correct answer from the choices listed above is the fourth option. The factor of the expression given as <span>10x^2 − 19x^6 would be 1 only. None of the other choices would factor correctly the expression. Hope this answers the question. Have a nice day.</span>
