Answer:
$1615.05
Step-by-step explanation:
First the cost. We know that tuition per credit hour is 113.67 and there is a flat fee of 660. This can be represented by 113.67h + 660, where h is equal to the number of credit hours.
Next, the amount paid. There are two constants of 350 and 400 already there. We can represent the remaining amount that needs to be paid by another variable, x.
Now, the cost needs to be equal to the amount you pay. We can replace h with 15 for 15 hours and solve for x.
113.67h + 660 = 350 + 400 + x
113.67(15) + 660 = 350 + 400 + x
1705.05 + 660 = 750 + x
2365.05 = 750 + x
1615.05 = x
Ok so the triangle part is 10 but I don’t know what the rectangle part is but the formula for a rectangle is A=base x high
X^2-5x, given x=7,
(7)^2-5(7)=14
sqrt(14)=3.74
Answer:
IJ is going to be 5400.
Step-by-step explanation:
60*90= 5400.
90 is the right angle on J.
I is 60 degrees.
Considering the unit circle, it is found that the sine is negative on the third and on the fourth quadrant.
<h3>What is the unit circle?</h3>
For an angle 
the unit circle is a circle with radius 1 containing the following set of points: 
.
Hence, from the above explanation, the sine is negative when y is negativem, which is on the third and on the fourth quadrant.
