Answer:
Step-by-step explanation:
"Theorem 9-13: The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside the circle is equal to half the difference of the measures of the intercepted arcs."
Basically no matter what other circle, secant or tangent you get, you just use the formula 
If you need the outer angle, just put the other angles in and solve
If you need the far or near point angle, re-arrange the formula to get that value.

Answer:
the solution means you can solve for either of the variables when one of the variables is known
Step-by-step explanation:
Given:
W=250+132.5T
Where,
W = weights in grams of the filled box
T = number of shirts in the box
T=8 when W=1310
W=250+132.5T
Substitute T = 8 into the equation
W = 250 + 132.5(8)
= 250 + 1,060
= 1,310
The solution means when number of shirts in the box is 8, the total weight in grams of the filled box is 1,310
It also means you can solve for the number of shirts if weight of the box is given as 1310
W=250+132.5T
1310 = 250 + 132.5T
1310-250 = 132.5T
1,060 = 132.5T
T = 1,060 / 132.5
= 8
T = 8
Therefore, the solution means you can solve for either of the variables when one of the variables is known
We have that
y = −14x² − 2x − 2
First, we need to transform the equation into its vertex form
(x - h)²=4p(y - k)
<span>Group
terms that contain the same variable
</span>y = (−14x² − 2x )− 2
<span>Factor the
leading coefficient
</span>y = -14*(x² + (2/14)x )− 2
<span>Complete
the square Remember to balance the equation
</span>y = -14*(x² + (2/14)x +(2/28)²-(2/28)²)− 2
y = -14*(x² + (2/14)x +(2/28)²)− 2+14*(2/28)²
y = -14*(x² + (2/14)x +(2/28)²)− 2+56/784
Rewrite as perfect squares
y = -14*(x+(2/28))²− 1512/784------>(x+1/14)²=(-1/14)*(y+1512/784)
4p=-1/14------> p=-1/56
This is a vertical parabola and its focus <span>(h, k + p)</span>
<span>h=-1/14</span>
<span>k+p=(-1512/784)+(-1/56)----> (-1512-14)/784)----> -1526/784</span>
<span>
</span>
<span>the focus is</span>
<span>(-1/14,-1526/784)</span>
Answer:
Y=7.5x
Step-by-step explanation:
8-5=3 and 60-37.5 is 22.5 divide 22.5 by 3 and you get 7.5 which is the rate that he earns an hour
