Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -8)

Point (-4, -4)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-4--1)^2+(-4--8)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-3)^2+(4)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{9+16}$
[√Radical] Add: $\displaystyle d = \sqrt{25}$
[√Radical] Evaluate: $\displaystyle d = 5$

Door is 77 inches high, 35.25 inches wide and 1,75 inches thick how much paint is needed

Leviafan [203]

If you wanted to paint the entire door (even the top and bottom which people don't usually paint)

the surface area is
SA=2(LW+LH+WH)
where L=length, W=width and H=height

given
L=35.25
W=1.75
H=77

SA=2(35.25*1.75+35.25*77+1.75*77)
SA=2(61.6875+2714.25+134.75)
SA=2(2910.6875)
SA=5821.375

you need enough paint to cover 5821.375 square inches of door

WORTH 20 POINTS, PLEASE ANSWER CORRECTLY! (THE ANSWER IS NOT 26.005)

alekssr [168]

Answer:

23.590 feet

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle:

Tan = Opposite/Adjacent

Here, that means ...

tan(65°) = height/(11 ft)

Multiplying by 11 ft, we get ...

height = (11 ft)tan(65°) ≈ 23.5896 ft

height ≈ 23.590 ft
