You meet with the financial aid office to discuss your costs for attending MGA next semester. Tuition is
NARA [144]

Answer:

$1615.05

Step-by-step explanation:

First, you need to determine the total cost for taking 15 credit hours:

Total cost=660+(113.67*15)

Total cost=$2,365.05

Now, you can subtract from that the amount of the grant and the scholarship you receive:

$2,365.05-$350-$400=$1615.05

According to this, the answer is that if you are taking 15 credit hours, you will need to pay $1615.05 for your classes next semester.

Simplify the trigonometric expression.
Natasha_Volkova [10]
First we are going to find the common denominator of both fractions. To do that, we are going to multiply their denominators:
(1+sin \alpha )(1-sin \alpha )=1-sin^2 \alpha

Now we can rewrite our expression using the common denominator:
\frac{1-sin \alpha }{1-sin^2 \alpha } + \frac{1+sin \alpha }{1-sin^2 \alpha} = \frac{2}{1-sin^2 \alpha}

Finally, we can use the trig identities: 1-sin^2 \alpha =cos^2 \alpha and sec \alpha = \frac{1}{cos \alpha } to simplify our trig expression:
\frac{2}{cos^2\alpha}=2sec^2 \alpha

We can conclude that the correct answer is the fourth one.
