Answer:

(3, -1), 7

Step-by-step explanation:

To find the center of this circle: compare the given equation

(x - 3)^2 + (y + 1)^2 = 7^2 to the standard equation of a circle with center at (h, k):

(x - h)^2 + (y -k)^2 = r^2

From this comparison we see that the center is at

h = 3 and k = -1, and also that r must be 7: (3, -1), 7

Suppose you have $10,000 to invest. Which investment yields the greater return over 7 years: 6.6% compounded monthly or 6.7% com

joja [24]

Answer:

C) $10,000 invested at 6.7% compounded quarterly over 7 years yields the greater return.

Step-by-step explanation:

-We determine the effective interest rate in both scenarios and use it to calculate the investment's value after 7 years.

#Given n=7yrs, P=$10,000 and i=6.6% compounded monthly:

$i_m=(1+i/m)^m-1\\\\=(1+0.066/12)^{12}-1=0.06803\\\\\therefore A=P(1+i_m)^n\\\\=10000(1.06803)^7\\\\\approx \$15,852.00$

#Given n=7rs, P=10000, i=6.7%

$i_m=(1+i/m)^m-1\\\\=(1+0.067/4)^{4}-1=0.06870\\\\\therefore A=P(1+i_m)^n\\\\=10000(1.06870)^7\\\\\approx \$15,921.75$

Hence, the investment has the largest value($15,921.75) when the interest rate is compounded quarterly.

Solve X^4=4^X assist by solving for value of x

Anton [14]

Answer:

x ∈ {−0.766664695962, 2, 4}

Step-by-step explanation:

The equation is a combination of polynomial and exponential functions. There are no algebraic methods for solving such an equation. Graphical and iterative methods work nicely, though.

The attached graph shows integer solutions at x=2 and x=4. There is also an irrational negative solution near x = −0.766664695962. The latter was found by using Newton's method iteration on the graphical value of -0.767.

A new cream was developed to reduce the irritation caused by poison ivy. To test the effectiveness, researchers put an ad online

telo118 [61]

Answer:

Single Blind (option 1)

Step-by-step explanation:

The subjects don't know which cream they have but the technicians do.

If the subject knows which cream they have then they can be influenced by the placebo effect. If they don't know but the technicians do then the technicians will be able to look at unbiased responses from the subjects and tell if it works or not. If the technicians don't know which cream each subject has then they won't be able to learn anything from the responses. The technicians need to know which cream each subject has and the subjects can't know which cream they had.
