PLEASE HELP :( I Can’t figure it out
Bogdan [553]

Answer:

y=32.0

Step-by-step explanation:

Use the sine ratio;

Recall the mnemonics SOH-CAH-TOA

\sin y=\frac{Opposite}{Hypotenuse}

Substitute Opposite =9 and Hypotenuse =17

\sin y=\frac{9}{17}

Take sine inverse:

y=\sin^{-1}(\frac{9}{17})

y=32.0

Convert 100/1000 to a decimal
Yanka [14]

Answer: 0.1

Step-by-step explanation:

100/1000 is equivalent to 1/10, and 1/10 becomes 0.1 when divided because it is one out of ten; one tenth.

Given the figure below, how much paper is needed to make the drinking cup to the nearest square inch?
miskamm [114]
To find this, we need to find the Surface area of the lateral surface of the cone (without the circle base). 
LSA _{cone} =  \pi rl
Now we just need to plug what we know into the equation
r=1.5 \\l=4
LSA _{cone} =  \pi (1.5)(4) \\LSA_{cone}= 6\pi
Wither you can keep your answer in pi or take it out of pi, depending on what the requirements are. 
To take it out of pi you need to multiply 6 by pi (remembering to use 3.14 as pi in most cases since that is what is generally accepted on tests and exams). 
6 \pi = 6(3.14)= 18.84
Then rounding to the nearest square inch which would mean that the amount of paper needed is =19in²

The given line passes through the points (0, -3) and (2, 3).
rodikova [14]

Answer:

y + 1 = 3( x + 1)

Step-by-step explanation:

We are asked to find the equation of the line in point-slope form

Step 1 : find the slope using the two points given

( 0 , -3) ( 2,3)

m = (y_2 - y_1) / (x _2 - x_1)

x_1 = 0

y_1 = -3

x_2 = 2

y_2 = 3

Insert the values into

m = 3 - (-3) / 2 - 0

m = 3 +3 / 2 - 0

= 6/2

= 3

Step 2: it was given in the question that the parallel to a given line and passes through ( -1 , -1)

Substitute the point into the equation

y - y_1 = m ( x - x _1)

m = 3

y - y_1 = 3 ( x - x_1)

x_1 = -1

y_1 = -1

y - (-1) = 3( x - (-1)

y +1 = 3 ( x + 1)

We don't need to open the bracket because we are asked to give the answer in a point-slope form

The equation of the line in point slope form is

y + 1 = 3( x + 1)
