Answer:

A. This is a function because every input maps to only one output.

D. Cubic Function

Step-by-step explanation:

For this mapping to be considered a function it must only have one y-value for each x value. This is the case, and this is what option A describes.

From its shape, we can see that D is a cubic function. Let's look at the shapes of each of the other functions just to be sure.

A. Linear Function

This graph would be a line.

B. Absolute Value Function

This graph would be in a "V" shape

C. Quadratic function

This graph would be in a "U". or parabolic shape

D. Cubic Function

This would have the same basic shape as the one in the graph.

Faction Equivalent demcimal for 2.46

Paul [167]

Here is you're answer:

In order to find the answer you have to switch all the options into decimals to see which one is equivalent to 2.46!

$\frac{246}{1000}$
$\frac{246}{1000} = 246 \div 1000 = 0.246$
$2\frac{46}{1000}$
$2\frac{46}{1000} = \frac{1023}{500} = 1023 \div 500 = 2.046$
$2 \frac{23}{50} = \frac{123}{50} = 123 \div 50=2.46$ <-- You're answer.
$\frac{223}{500} = 223 \div 500 = 0.446$

Therefore you're answer is option C "2 23/50." Remember when wanting to find the decimal divide the numerator by the denominator after you convert the mixed number (if it's a mixed number) into a improper fraction!

Hope this helps!

A credit card issuer offers an APR. of 22.08% and compounds interest daily. Which is it most likely to advertise, its APR or it’

Alex

Answer: The credit card issuer will show APR which is 22.08% and not effective rate of interest. This is because Effective rate, when calculated with the formula given below will come as 24.67% which is 2.59% more and hence will make customers feel that they are paying more. r = [ { (1+ i / n) ^ (n) } - 1] * 100 Where i = APR/100 n = number of compounding periods which is 365 in this case as compounding is done daily. [ { (1+ 0.2208 / 365) ^ (365) }- 1] * 100

the length of diagonal of a rectangular field is 23.7 m and one of its sides is 18.8 m. find the perimeter of the field.

katen-ka-za [31]

Answer:

Approximately 66.4 Meters

Step-by-step explanation:

So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.

$a^2+b^2=c^2$
