Answer:

D.

B.

Step-by-step explanation:

for the first one remember that hypotenuse² = cathetus1² + cathetus2²

which leads to the second question

WA²(hypotenuse) = XA²+WX²

therefore XA²=WA²-WX²=81

XA=√81=9

Answer:

1st pic : 3²+4²=5²

2nd pic: 9 in.

Step-by-step explanation:

According to Pythagoras theorem , in a right angled triangle, where

the longest side (opposite to the right angle) say its length X , the other two sides say Y,Z.

X² = Y² + Z²

Y² = X² - Z²

Z² = X² - Y²

A computer with software costs $2,938, and Catherine Stevens has agreed to pay a
Scorpion4ik [409]

Answer: She will pay 209.74056 each month

Step-by-step explanation:

firstly our cost of computer software = 2938

now the  percentage rate of the finance charge per 18 months will be

finance charge rate per 18 months = (rate/12) * 18 =  (19/12) * 18 = 28.5% = 0.285

now we find the finance charge

Finance charge = finance charge rate period * cash price

Finance charge = 0.285 * 2938 = 837.33

now we find the installment price

Installment price = finance charge + cash price

Installment price = 837.33 + 2938 = 3775.33

Installment payment = installment payments/number of payment (months)

Installment payment = 3775.44 / 18 = 209.74056

therefore she will pay a sum of 209.74056 each months.

A disco ball is shaped like a sphere with a diameter of 16 inches. To the nearest square inch, what is the surface of the disco
Mademuasel [1]
If the diameter is 16 inches, then its radius is half that, r = 8.

\bf \textit{surface area of a sphere}\\\\
A=4\pi r^2\quad 
\begin{cases}
r=radius\\
-----\\
r=8
\end{cases}\implies A=4\pi 8^2

What is the slope of the line that goes through the points (1, -5) and (4, 1)
tangare [24]

Answer:

D) 2

Step-by-step explanation:

Use the following slope formula:

<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (4 , 1)

(x₂ , y₂) = (1 , -5)

Plug in the corresponding numbers to the corresponding variables:

<em>m</em> = (-5 - 1)/(1 - 4)

Simplify. Remember to follow PEMDAS. First subtract, then divide:

<em>m</em> = (-5 - 1)/(1 - 4)

<em>m</em> = (-6)/(-3)

<em>m</em> = 2

D) 2 is your answer.

Which function could be represented by the graph on the coordinate plane?
Nat2105 [25]
The answer is the 4th one. The native form of cuadratics is x^2, therefore its transformation is 8 units to the right and six down. -8 inside the parenthesis means it moves to the opposite of the x line, so if the graph was on the left side of y, the 8 would be positive.
