Ok so
The answer would be the second one (3+3+3+3=3 (4) )
Here's the explanation
It doesn't belong there because all the rest have to do with exponents
And that problem does not
Also,that problem uses repetitive addition while the other ones use repetitive multiplication
Hope this helps :)

1. The proceeds of a $7,500.00, 10 percent simple discounted note for 85 days is

Simora [160]

Answer:

it depends (see below)

Step-by-step explanation:

<u>Exact Interest</u>

Exact interest is calculated on the basis of a 365-day year, so the exact interest on the loan would be ...

I = Prt = $7500·0.10·(85/365) = $174.66

Then the proceeds would be ...

$7500 -174.66 = $7,325.34 . . . . . matches first option

<u>Ordinary Interest</u>

Exact interest is calculated on the basis of a 360-day year, so the ordinary interest on the loan would be ...

I = Prt = $7500·0.10·(85/360) = $177.08

Then the proceeds would be ...

$7500 - 177.08 = $7,322.92 . . . . . matches last option

_____

I suggest you check your reference materials (text or course examples) to see what year length is expected to be used in this calculation. Some on-line references show it one way; others show it the other way.

Suppose the diameter of a circle is 6 units.what is its circumference?

salantis [7]

Answer:

18.85

Step-by-step explanation:

So the circumference of a circle = 2πr

if the diameter is 6, then the radius is 3.

so 2π(3)

= 6π

= 18.85 units of measurement

Which is the equation of a hyperbola with directrices at y = ±2 and foci at (0, 4) and (0, −4)?

Advocard [28]

Answer:

Step-by-step explanation:

First off, I'm assuming that when you said "directrices" you mean the oblique asymptotes, since hyperbolas do not have directrices they have oblique asymptotes.

If we plot the asymptotes and the foci, we see that where the asymptotes cross is at the origin. This means that the center of the hyperbola is (0, 0), which is important to know.

After we plot the foci, we see that they are one the y-axis, which is a vertical axis, which means that the hyperbola opens up and down instead of sideways. Knowing those 2 characteristics, we can determine that the equation we are trying to fill in has the standard form

$\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1$

We know h and k from the center, now we need to find a and b. Those values can be found from the asymptotes. The asymptotes have the standard form

y = ± $\frac{a}{b}(x-h)+k$

Filling in our asymptotes as they were given to us:

y = ± $\frac{2}{1}(x-0)+0$ where a is 2 and b is 1. Now we can write the formula for the hyperbola!:

$\frac{(y-0)^2}{4}-\frac{(x-0)^2}{1}=1$ which of course simplifies to

$\frac{y^2}{4}-\frac{x^2}{1}=1$
