What is the value of 2m² + 12 when m = 3?
A. 24
B. 30
C. 37
D. 38

Answers

Answer 1

Answer:

B. 30

Step-by-step explanation:

2m^2 + 12

m = 3

2(3)^2 + 12

3 squared is 9

2(9) + 12

2 times 9 is 18

18 + 12 = 30

2m^2 + 12 = 30

Answer 2

So we subtitute 3 to any "m" in your problem so,

2m^2+12

2(3)^2+12

2(9)+12

18+12

30

So,  B is the correct answer!

how is the answer 4?? ​

Answers

Answer:

see below

Step-by-step explanation:

log sqrt5  (25) = y

we know that loga (b) = c  can be rewritten as  a^c = b

sqrt(5) ^ y = 25

Rewriting sqrt(5) as 5^1/2  and 25 as  5^2

5^1/2 ^ y = 5^2

we know a^b^c = a^ (b*c)

5 ^ 1/2y = 5^2

1/2y = 2

y = 4

Jodie wants to raise money for a school trip by selling raffle tickets at a basketball game. She sells each ticket for 50 cents, and she sells two and a half rolls of tickets. If each roll of ticket has 200 tickets, how much money did Jodie make?

Answers

Answer:

250 dollars

Step-by-step explanation:

t = tickets

t = 200

Two and a half rolls tickets = (200 x 2) + 200/2) = 400 + 100 = 500

500 tickets x 50 cents = 25000 cents

convert cents to dollars (move decimole point over left 2 units)

25000 = 250 dollars

The correct answer is C - 7.8 < 7 5/6 < 7.9

Step-by-step explanation:

First, convert 7 5/6 to decimal form --> 7.83.

If you don't know how to convert, think about what 5/6 is equal to and put it in decimal form. Add your decimal to the whole number, and there is your answer.

7.83 is in between 7.8 and 7.9, so it must be the answer.

Jared’s average daily balance for last month was $560. The finance charge was $8.12.

a. What was the monthly percentage rate?
b. What was the APR?

Answers

Answer:

A) monthly percentage rate = 1.45%

B) APR = 17.4%

The monthly percentage rate was 1.45 % and the annual percentage rate was 17.4%.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

We have been given that Jared’s average daily balance for last month was $560. The finance charge was $8.12.

We have to determine the monthly percentage rate.

The monthly percentage rate is the percentage ratio of the finance charge to the average daily balance.

The monthly percentage rate = finance charge / average daily balance

The monthly percentage rate = $8.12 / $560 × 100

The monthly percentage rate = 0.0145 × 100

The monthly percentage rate = 1.45 %

The Annual percentage rate = 12 × monthly percentage rate

The Annual percentage rate = 12 × 1.45 %

The Annual percentage rate = 17.4 %

Therefore, the monthly percentage rate was 1.45 % and the annual percentage rate was 17.4%.

A researcher is following the growth of a particular type of flower. She writes the given equation to show the height of the flower g(n), in inches, after n days.


g(n) = 10(1.02)n


What does the average rate of change of the function represent?


A.
the number of days flower grew

B.
the average height of the flower after 5 days

C.
the average growth of the flower from day 1 to day 5

D.
the average time it takes for the flower to grow from 1-5 inches

Answers

The expression given represents an exponential growth relation. The average rate of change is the average growth of the flower from day 1 to days 5

The rate of change of the flower can be deduced frommthe equation as :

1.02 - 1 = 0.02

Hence, the growth rate of the flower per day = 0.02

The number of days, n = 5

Therefore, the average growth rate is the average growth of the flower within the number of days given.
