F(x)=3x+1 and g(x)=x^2-6 find (f+g)(x)

Answers

Answer 1
Answer: Answer is x^2 + 3x - 5 As, f(x) = 3x + 1 And g(x) = x^2 - 6 We have to find (f+g)(x) For that we should know (f+g)(x) = f(x) + g(x) So it will become = (3x + 1) + (x^2 - 6) = 3x + 1 + x^2 - 6 = x^2 + 3x - 5
Answer 2
Answer:

Answer:

It would be x^2 + 3x - 5.

Answer:

B. Bertha's dive ended 6 times farther than Vernon's dive.

Step-by-step explanation:

We have that,

Bertha's dive ended -24 m from that starting point.

Vernon's dive ended -4 m from that starting point.

So, we get that,

Bertha's end point = 6 × Vernon's end point

i.e. -24 = 6 × (-4)

So, we see that,

Bertha's dive ended 6 times farther than Vernon's dive.

The value of a car depreciates by 18% per year. Work out the current value of a car bought 4 years ago for £20000

Answers

Given:
depreciation rate: 18%
Value of the car : 20,000
Age of the car : 4 years.

The depreciation is based on the current value of the car. Therefore, the amount of depreciation varies.

yr   Beginning Value   Dep. Rate    Depreciation      Ending Value
1   20,000.00                 18%             3,600.00          16,400.00
2   16,400.00                 18%             2,952.00          13,448.00
3   13,448.00                 18%             2,420.64          11,027.36
4   11,027.36                 18%             1,984.92            9,042.44

The current value of a car bought 4 years ago is 9,042.44

Beginning value : purchased amount on 1st year. then, ending balance of the previous year from 2nd year onwards.
Depreciation : Beginning value * depreciation rate
Ending value : Beginning value - depreciation

20000 = 100%18 x 4 = 72%20000 / 100 = 200200 = 1%200 x 72 = 14,40020000 - 14,400 = 5600The value of it now should be £5600

What percentage of the audience from the 16-25 age group gave the movie a poor rating?

Answers

We have to find what percent of the audience from the 16-25 age group gave the movie poor rating. There were 113 viewers from this group. There were 7 of them that gave the movie poor rating. We will use the proportion: 113 / 7 = 100% / x% . Then we will cross multiply: 113 x = 700; x = 700 : 113; x = 6.19%. Answer: A ) 6.19%.
