Determine the graph of the polar equation r = 25/10-25 sin(theta).

ludmilkaskok [199]

Answer:

graph A

Step-by-step explanation:

A graphing calculator can plot this function for you.

If you divide numerator and denominator by 25, you get ...

r = 1/(0.4 -sin(θ))

This will have asymptotes at θ = arcsin(0.4). At those values of θ, the value of r will change sign, so the graph cannot be a parabola or ellipse.

The graph of the hyperbola is the appropriate choice.

If the measure of an acute angle is represented by x, then the measure of its complement

Luba_88 [7]

Answer:

always true

Step-by-step explanation:

complement equals that angle plus another one adds to 90. If you know that it's less than 90 degrees, then you subtract it from 90 to get the other angle which is the complement. Hope this helps!

Sarah's two student loans totaled $12,000. One of her loans was at 6% simple interest and the other at 3%. After one year, Sarah

8_murik_8 [283]

Answer:

The loans are $4500 and $7500 respectively

Step-by-step explanation:

Let the principal amount of the two loans be x and y respectively.

This means x + y = 12,000 (I)

Now, for the first principal x, interest accrued will be

I = PRT/100

I = x * 6 * 1/100 = 6x/100

For the second principal, interest accrued will be;

I = y * 3 * 1/100 = 3y/100

Since the total interest is $585

That would be;

6x/100 + 3y/100 = 585

6x + 3y = 58500 (ii)

Now we have two equations to solve simultaneously.

Substitute x = 12,000 - y in equation ii

6(12000- y) + 3y = 58,500

72000 - 6y + 3y = 58500

3y = 72000 - 58500

3y = 13,500

y = 13,500/3 = 4,500

x = 12,000 - y = 12000 - 4500 = 7,500

Hence the loan at 6% is 7,500 while the loan at 3% is 4,500
