Sati [7]

Answer:

x = \sqrt{11.4^2+2.6^2}\\\\

Rounded to the nearest hundredths: 11.69.

Step-by-step explanation:

I would use the Pythagorean theorem for this problem.

The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.

Now, just solve using Pythagorean's theorem:

x = \sqrt{11.4^2+2.6^2}\\\\

Rounded to the nearest hundredths: 11.69.

I hope this helped you.

After a new $28,000 car is driven off the lot, it begins to depreciate at a rate of 18.9% annually.
REY [17]

Answer:

C(t) = $28,000(0.811)^t  (Answer A)

Step-by-step explanation:

The value of the car is decreasing.  Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.

Please use " ^ " to indicate exponentiation.

Then the desired formula is C(t) = $28,000(0.811)^t  (Answer A)

1. Which monomial has the same degree as 6a2b8c? A 18t8 B 12p6q5 C 9a5b3c2 D 6w4x2y3z3
Olegator [25]

Answer: "B. 12p^6q^5

Step-by-step explanation:

The given monomial : 6a^2b^8c

Degree of this monomial = Sum of powers of variables=2+8+1= 11

Let's check all the options

A   18t^8

Degree = 8

B 12p^6q^5

Degree = 6+5 =11

C 9a^5b^3c^2

Degree = 5+3+2=10

D 6w^4x^2y^3z^3

Degree =4+2+3+3=12

We can see that only option B has degree 11.

So, the monomial has the same degree as 6a^2b^8c is "B. 12p^6q^5 "
