1. Find the phase shift of the function y = 5cos(2x + pi/2).

kolezko [41]

Answer:

see explanation

Step-by-step explanation:

1

The cosine function in standard form is

y = acos(bx + c)

where a is the amplitude, period = $\frac{2\pi }{b}$ and

phase shift = - $\frac{c}{b}$

here b = 2 and c = $\frac{\pi }{2}$ , thus

phase shift = - $\frac{\frac{\pi }{2} }{2}$ = - $\frac{\pi }{4}$

2

the amplitude = | a |

which has a maximum of a and a minimum of - a

y = 4cosx ← has a maximum value of 4

Which equation could represent a circle with a center located at (11,-5)

Anon25 [30]

The standard equation of a circle is:

$(x-h)^2-(y-k)^2=r^2$ where (h,k) is the center and r is the radius.

We need to make an equation of a circle, whose center is (11,-5) with any radius. Therefore, substitute the value.

$(x-h)^2-(y-k)^2=r^2 \\ (11,-5)=(h,k) \\ (x-11)^2-(y-5)^2=64$

The bolded part is your answer. Since the radius is not given, we can put any value.

Jameson has 4300 in credit card debt with 14% interest that he wants to pay off in 24 months. He will need to make monthly payme

lakkis [162]

Answer:

Total cost of repayment $= 4955.04$

Net interest paid $= 655.04$

Step-by-step explanation:

Given

Amount taken on loan $= 4300$

Repayment plan

Monthly installment $=$ $206.46$

Yearly installment $= 206.46 * 12 = 2477.52$

Rate of interest per year $= 14$ %

Time Period for repaying the loan $= 2$ years

The total amount repaid by Jameson at the rate of $206.46$ per month for next $24$ months

$= 206.46 *24\\= 4955.04$

Net interest paid

$= 4955.04 - 4300\\= 655.04$

Total cost of repayment $= 4955.04$

Net interest paid $= 655.04$
