Kites have two pairs of equal sides with one side shorter than the other. However, parallelograms have two pairs of equal sides, but they are parallel.

Which set of side lengths form a right triangle?

astraxan [27]

Since we don't want to use the Pythagorean Theorem on all of these, first we look for some Pythagorean Triples. Its very helpful to know some of the common ones, so here's a list:

3, 4, 5
5, 12, 13
7, 24, 25
8, 15, 17

So we either look for these or a multiple of these numbers.

The last one is the only one that fits because 15, 20, 25 is a multiple of the triple 3, 4, 5 by multiplying all of them by 5.

Thus, 15, 20, 25 forms a right triangle.

Harman [31]

Adam got the sum of his grades right, but he divided that correct figure by 6, getting 84 Before that division, the sum of his grades must have been 84 * 6, or 504. He should have divided 504 by 7, getting 72. Answer: His correct average test score is 72.

Answer:

(a) Brenda saved $23.50.

(b) The rate at which Brenda is saving money is<u> 0.5 dollars per day</u>.

(c) money saved on $J(14)$ is <u>$27.</u>

Step-by-step explanation:

Given:

Initial amount in the jar is, $J(0)=\$20$

Amount in the jar after a week or 7 days is, $J(7)=\$23.50$

Brenda is saving money at a linear rate.

(a)

Now, money at the end of the week is the total money saved by Brenda.

Therefore, total money saved by Brenda is equal to the money saved at the end of the week. So,

Total money saved by Brenda = $J(7)=\$23.50$

(b)

The rate of change of a function is given as:

$Rate=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

Here, $x_1=0,x_2=7, f(x_1)=J(0),f(x_2)=J(7)$

Therefore, the rate at which Brenda saves money is given as:

$Rate=\frac{J(7)-J(0)}{7-0}\\Rate=\frac{23.50-20}{7}\\Rate=\frac{3.5}{7}=0.5\ dollars/day$

Therefore, the rate at which Brenda is saving money is<u> </u>0.5 dollars per day.

(c)

A linear function is of the form $f(x)=mx+b$ , where 'm' is the rate and 'b' is the initial value of the function.

Therefore, the linear function for the money saved by Brenda can be written as:

$J(x)=(Rate)x+J(0)\\J(x)=0.5x+20$

Now, $J(14)$ is given by plugging in 14 for 'x' in the above expression. So,

$J(14)=0.5\times 14+20\\J(14)=7+20=\$27$

Therefore, money saved on $J(14)$ is $27.

SpyIntel [72]

Given function:

$f(x)=4 x^{3}=c$

To find:

The input if the output is 32.

The output if the input is 4.

Solution:

Input is x and output is c.

Substitute c = 32 in f(x).

$4 x^{3}=32$

Divide by 4 on both sides, we get

$x^{3}=8$

$x^{3}=2^3$

Taking cube root on both sides.

$x=2$

The input is 2 if the output is 32.

Substitute x = 4 in f(x).

$4 (4)^{3}=c$

$4 (64)=c$

$256=c$

The output is 256 if the input is 4.
