Answer:

see below

Step-by-step explanation:

The co-vertex is 2 units from center in the x-direction, so the denominator of the x-term will be 2² = 4. Only two answer choices match.

The major axis is parallel to the y-axis, so the foci will have different y-coordinates. Of the two answer choices just found, only one of them has the foci on a vertical line: the choice shown below.

_____

If you actually want to write the equation, note that the center of the ellipse is (-4, -3), and the semi-major axis is 4 units in the y-direction. The standard-form equation will be ...

(x+4)/2² +(y+3)/4² = 1

The distance from center to a focus will be the root of the difference of the denominators, so is √(16-4) = 2√3. That is the distance along the semi-major axis, so puts the foci at (-4, -3±2√3).

Answer:

<em>Donna will have to pay $67.985125 at the register, including the 7% sales tax.</em>

Step-by-step explanation:

Donna bought 3 pairs of pants for $28.50 each.

So, the cost for 3 pair of pants $=(28.50\times 3)dollars= 85.50$ dollars.

She also bought a necklace for $12.25

Thus, the cost for her entire purchase will be: $(85.50+12.25) dollars = 97.75$ dollars.

She received a discount of 35% off her entire purchase. So, the amount of discount $=(97.75\times 0.35)= 34.2125$ dollars.

Thus, the total selling price will be: $(97.75-34.2125)= 63.5375$ dollars.

Percentage of sales tax is 7%. So, the amount of sales tax $=(63.5375\times 0.07)= 4.447625$ dollars.

Thus, the total amount Donna have to pay at the register $=(63.5375+4.447625)=67.985125$ dollars.

If f(x)=8x and g(x)=2x+1, what is (f×g)(x)

Sav [38]

Answer:

(f * g)(x) has a final product of 16x² + 8x.

Step-by-step explanation:

When you see (f * g)(x), this means that we are going to be multiply f(x) and g(x) together.

<em>f(x)=8x</em>

<em>g(x)=2x+1</em>

Now, we multiply these terms together.

(8x)(2x + 1)

Use the foil method to multiply.

16x² + 8x

So, the product of these terms is 16x² + 8x.

How many solutions does this equation have?

Greeley [361]

Answer:

No solution

Explanation:

-4+19-7f = -15-7

cancel terms on both sides ( add 7f on both sides)

Calculate the sum

-4+19= -15

-4+19=15

15 = -15

The statement 15 = -15 is false so there is no solution :)
