Answer:
(3 7/8, 2 3/4)
Step-by-step explanation:
To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.
Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.
Now we have our x and y coordinates.
(3 7/8, 2 3/4)
Answer: x = 30
∠H = 75
∠I = 75
Step-by-step explanation:
Write out this equation for solving interior angles
The sum of all 3 angles will equal 180
(2x+15) + (3x-15) + 30 =180
2x + 3x +30 + 15 -15 = 180
2x + 3x + 30 = 180 ( subtract 15 from 15 )
2x + 3x + 30= 180
-30 -30 ( from both sides)
2x + 3x = 150
5x = 150
Divide
x=30

To solve this we are going to use the formula for the nth term of a geometric sequence:

where

is the nth term

is the first term

is the common ratio

is the place of the term in the sequence
Notice that we can infer for our problem that

and

.
Now, to find our common ratio, we are going to use the formula

where

is the current term in the sequence

is the previous term in the sequence
for

and

:


Since

, we can conclude that

.
Notice that the first therm of our geometric sequence is -5, so

. Since

, we can conclude that

.
We can conclude that the values of B and C in our geometric sequence are: 
and

.
