Answer:

Option D - 39.09%

Step-by-step explanation:

Given : A credit card had an APR of 33.01% all of last year and compounded interest  daily.

To find : What was the credit card's effective interest rate last year?

Solution :

Effective annual rate formula is given by,

\text{APR}=(1+\dfrac{r}{n})^n-1

where, r is the interest rate i.e. r=33.01%=0.3301

n is the number of time period for which interest is compounded daily i.e. n=365.

Substitute in the formula,

\text{APR}=(1+\dfrac{0.3301}{365})^{365}-1

\text{APR}=(1+000904)^{365}-1

\text{APR}=(1.000904)^{365}-1

\text{APR}=1.39089-1

\text{APR}=0.39089

Into percentage,  

\text{APR}=0.39089\times 100

\text{APR}=39.089\%

\text{APR}\approx 39.09\%

Therefore, the credit card's effective interest rate last year is 39.09%.

So, Option D is correct.

Write as a product: ax^2+ay^2–bx^2–by^2+b–a
Vesna [10]

Answer:

\large\boxed{ax^2+ay^2-bx^2-by^2+b-a=(a-b)(x^2+y^2-1)}

Step-by-step explanation:

ax^2+ay^2-bx^2-by^2+b-a\\\\=(ax^2-bx^2)+(ay^2-by^2)+(b-a)\qquad\text{use the distributive property}\\\\=x^2(a-b)+y^2(a-b)-1(a-b)\\\\=(a-b)(x^2+y^2-1)

Find the distance between the two given points. (-6, -5) and (2, 0)
Ipatiy [6.2K]

Answer:

The answer is

<h2>\sqrt{41}  \:  \:  or \:  \:  \: 6.403 \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{( {x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance is

d =  \sqrt{ ({ - 6 - 2})^{2} +  ({ - 5 - 0})^{2}  }  \\  =  \sqrt{ ({ - 4})^{2}  +  ({ - 5})^{2} }  \\  =  \sqrt{16 + 25}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

\sqrt{41}  \:  \:  or \:  \:  \: 6.403 \:  \:  \: units

Hope this helps you

Tyler buys 3 cans that each contain 3 quarts of blue paint, and he buys 1 can that contains 2 quarts of white paint. What is the
Serga [27]
Tyler has 3 cans of blue paint. Each contains 3 quarts separately. What you need to do is multiply 3 and 3, which would total to 9 quarts. Since you need to include exponents, I´m guessing 3 cubed (3 to the third power) will work. He also buys 1 can of white paint, which only contains 2 quarts. You should add that to the 9 quarts we got from the last steps. I am not sure if this answer is entirely correct, but my guess is 3^3 + 2 = 11 quarts.
