Answer:

4. a vertex at (0, 96) is CORRECT

5. the center at (0, 0) is CORRECT

From the given equation,

a = 40

b = 96

(h,k) = (0,0), the center

The vertices are at (0,96) and at (0, -96).

The curves open upward and downward.

c² = a² + b² = 40² + 96² = 10816

c = 104

Therefore the foci are at (0, -104) and (0, 104).

Check the given answers:

1. a focus at (104, 0) is INCORRECT

2. a focus at (0, -96) is INCORRECT

3. a vertex at (-40, 0) is INCORRECT

4. a vertex at (0, 96) is CORRECT

5. the center at (0, 0) is CORRECT

Help please with this math question

Vanyuwa [196]

To solve this question, simply use the formula to find the volume of the cylinder,

V = Pi r^2 • h

V = 3.14 • 4^2 • 4.

Then compare the value for volume to the closest number on the number line. Is it in between 2 numbers, exactly one number on the number line or very close to one number as in the number line.

Convert 0.83 into a fraction.

Anastasy [175]

0.83 * 100 = 83, so 0.83 = 83/100.

But in case you meant the slightly more interesting repeating decimal, 0.8333...:

Let x denote this number. Then

10x = 8.333...

100x = 83.333...

==> 100x - 10x = 83.333... - 8.333...

==> 90x = 83 - 8 = 75

==> x = 75/90 = 5/6

Chance bought a surf board for 249. Now it's on sale for 221.10. Find the percent of the discount

Masteriza [31]

Answer:

Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.

Solution:

Step 1:

Bought price= RS.249

Sale price=RS.221.10

Step 2:

Discount = bought price - sales price

Discount = 249 - 221.10

Discount = 27.9

Step 3:

Discount Percent = $\frac{\text {Discount}}{M R P} \times 100$

Substitute the value for Discount which we found in step 2 in the above formulae

Discount Percent = $\frac{27.9}{249} \times 100$

On simplification, we get

$\frac{27.9}{249} \times 100$

Discount Percent = 11.20%

Result:

Hence from the given data, we got the discount percent is 11.20%
