Answer:

Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.

Step-by-step explanation:

Given: A Right Circular Cone

To find: Shape of of cross section when cone is cut by a plan parallel

to edge of cone

Cone has an apex on top and circle in base so if it is cut parallel to its edge we get a shape which is curved or pointy on one end while on the other end it is open due to circle.

Option A: Circle is closed from everywhere,

Thus it is not correct.

Option B: Ellipse is also not open from any end.

Thus, it is not correct.

Option C: Parabola is curved from one end and open from other end.

Thus this is correct.

Option D: We get parabola if cone is cur parallel to axis.

Thus it is also not correct.

Therefore, Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.

(ab² + 13b - 4a) + (3ab² + a +7b)

Natalija [7]

Answer:

4ab² + 20b - 3a

Step-by-step explanation:

This question most likely asks us to simplify the expression, as factoring is not possible...

(ab² + 13b - 4a) + (3ab² + a + 7b),

ab² + 13b - 4a + 3ab² + a + 7b,

ab² + 3ab² + 13b + 7b - 4a + a,

Solution : 4ab² + 20b - 3a

Chem deposited $115.00 in a savings account. Each week thereafter, he

Yanka [14]

Answer:

Part a) $y=35x+115$

Part b) $\$1,165$

Step-by-step explanation:

Part a)

Let

x -----> the number of weeks

y ----> the total amount Chem has deposited in a saving account

we know that

The equation of a line in slope intercept form is

$y=mx+b$

where

m is the rate or slope of the linear equation

b is the y-intercept of the linear equation or initial value (value of y when the value of x is equal to zero)

In this problem we have that

The rate or slope is equal to

$m=35\frac{\$}{week}$ -----> amount deposited by Chem each week

The y-intercept or initial value is

$b=\$115$ ----> amount deposited originally in the saving account

substitute the values

$y=35x+115$

Part b) How much has Chem deposited 30 weeks after his initial deposit?

For x=30 weeks

substitute in the equation

$y=35(30)+115$

$y=\$1,165$

In June, Alexa's Army Reserve unit was called to active duty. To comply with the Uniformed Services Employment and Reemployment

alisha [4.7K]

Answer:

provide up to five years of active duty service leave and hold her job.

Step-by-step explanation:

The Uniformed Services Employment and Reemployment Rights Act is a law that was created in the United States to protect the employment rights of the military members and veterans requiring employers to get them their jobs back after they end their service. This applies when the reason for leaving was the military commitment, the employer received a notice about the situation and the absence was for less than 5 years. In that case, the person has to get the job back with all the benefits. According to this, the answer is that to comply with the Uniformed Services Employment and Reemployment Rights Act, Alexa's employer must provide up to five years of active duty service leave and hold her job.
