The curve described described here is an ellipse with eccentricity e=\dfrac45, the ratio between the distance from the given focus F(4, 0) to any point Q along the directrix x=\dfrac{25}4. Use this info to find the lengths of the semimajor and -minor axes, a and b. Then the area of the ellipse is \pi ab.

Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.
padilas [110]

The  expressions that could represent how much Leila pays in total for the model

\dfrac{107}{100}x

100 107 Option A is correct.

This is further explained below.

<h3>Which of the following expressions could represent how much Leila pays in total for the model?</h3>

The price of the model is  x

Now we are given that she also has to pay a 7  tax.

Amount of tax =7 % x

=\frac{7}{100} x

the Total cost=x+\frac{7}{100} x

=\frac{107}{100} x

In conclusion, the statement might signify Leila's overall cost for the model. \frac{107}{100} x

What is the slope of o line that passes through (-4,-14) and (19,11)?
DerKrebs [107]

Answer:

D, see description below.

There is a possible typo in the problem since these points have slope 25/23.

Step-by-step explanation:

To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

m=\frac{y_2-y_1}{x_2-x_1}

Here the points are (-4,-14) and (19,11). Substitute and simplify.

m=\frac{11--14}{19--4}=\frac{11+14}{19+4}=\frac{25}{23}

I think there is a typo in your points (-4,-14) and (19,11) because the answer doesn't align to the answer choices. But based on them, I would answer D or 24/23 since it's the closest value.

Write these fractions in least common denominator2/5x+15y 1/2x+6y
Over [174]
Look at deonomators

assuming that the deonomenators are 5x+15y and 2x+6y

find their LCM
factor

5x+15y=5(x+3y)

2x+6y=2(x+3y)

LCM=10(x+3y)=10x+30y

multiply 2/(5x+15y) by 2/2=4/(10x+30y)
multiply 1/(2x+6y) by 5/5=5/(10x+30y)

if we add them
9/(10x+30y)
