---------------------------------------
Question 2: 
---------------------------------------
a² + b² = c²
x² + 13² = 15²
x² = 15² - 13²
x² = 56
x = √56
x = 2√14 units

---------------------------------------
Question 4:
---------------------------------------
cos a° = adj/hyp
cos (30) = 12/y
y = 12 ÷ cos(30)
y = 12 ÷ 3√2
y = 4/√2 units

tan a = opp/adj
tan(30) = x/12
x = tan(30) x 12
x = 3√3 x 12
x = 36√3 units

Ok guys i have only 1 hr to get this. Determine the y-intercept for the equation 3x + 2y = 12. HELP
sukhopar [10]

Answer:

x= -2/3 y+4

Step-by-step explanation:

Let's solve for x.

3x+2y=12

Step 1: Add -2y to both sides.

3x+2y+−2y=12+−2y

3x=−2y+12

Step 2: Divide both sides by 3.

3x

3

=

−2y+12

How would I solve this equation for mass (m)?
zaharov [31]
Simple...

you have: F= \frac{G m^{2} }{ d^{2} }

You want to find m-->>>

1.)Isolate m

d^{2} *F= \frac{G m^{2} }{ d^{2} } * d^{2}

Leaving you with...

F*d^{2}=G m^{2}

Keep isolating m-->>>

F* d^{2} =G m^{2}

\frac{F* d^{2} }{G} = \frac{G m^{2} }{G}

Square root to solve what just m is-->>>

\sqrt{ \frac{F* d^{2} }{G} } = \sqrt{ m^{2} }

=\sqrt{ \frac{F* d^{2} }{G}  } =m

That is how you solve for m...

Thus, your answer.
