If Ab = 54, find MC.

Mathematics

Answer:

MC = 45

Step-by-step explanation:

Δ ABH and Δ MCH are similar and the ratios of corresponding sides are equal, that is

\frac{AB}{MC} = \frac{AH}{MH} , substitute values

\frac{54}{MC} = \frac{6}{5} ( cross- multiply )

6MC = 270 ( divide both sides by 6 )

MC = 45

Using f(x) = 4x + 6 with the domain of {-1,0,2}, find the range
konstantin123 [22]
The range is the output of the function, and there are many ways to find it and write it. Let's find it first by plugging in all the domain values (domain means input) into the function:
f(-1) = 4(-1)+6=-4+6=2
f(0) = 4(0)+6=0+6=6
f(2) = 4(2)+6 = 8+6=14

We have all of our values. We can either write the range as:
{2, 6, 14}

or, subtract the smallest value from the largest one:
14-2=12

So, there are those ways to write it, there are more, but I think you should stick with the first way because that's how the problem was presented to you. If you have any questions, hmu!

H(x) = x^2 + 1 k(x) = x – 2<br> (h + k)(2)=?
likoan [24]
First we will compute the h+k and then multiply the result by 2.
To add polynomials, we add terms whose variables are alike, for example:
we add the coefficients of x^2 together, the coefficients of x together and so on.

Therefore:
h + k = x^2 + 1 + x - 2 = x^2+x-1

Now, we will multiply this answer by 2 to get the final answer:
2(h+k) = 2(x^2+x-1) = 2x^2 + 2x -2

the runner's time to complete the marathon is 45 minutes. The time to complete the last marathon was 49.5 minutes. What is the p
Lana71 [14]

Answer:

9.09%

Step-by-step explanation:

To find percent decrease you have to use this equation:

Percent Decrease = \frac{Initial -New}{Initial} x 100

Initial = 49.5

New = 45

Plug in and solve:

PD = \frac{49.5-45}{49.5} x 100\\\\PD = \frac{4.5}{49.5} x 100 \\\\PD = 0.0909 x 100\\\\PD = 9.09

The percent decrease is 9.09%
