Given that QT is an altitude of triangle QRS, measure of angle QTS=(6x+36), and QR = 2x – 5, find QR. a. 7
b. 9
c. 11
d. 13

Answers

we know that
if QT is an altitude of triangle QRS
then
the measure of angle QTS is equal to 90°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13

the answer is
QR=13

The volume of a cone is 258.9 cubic centimeters. a cylinder has the same base and height as the cone. what is the volume in cubic centimeters of the cylinder

Answers

Volume of a cylinder = A(base)*height

Volume of a cone = 1/3*A(base)*height

Because the base and height of the cylinder and cone are the same, we can write

Volume of the cone = 1/3*A(base)*height =1/3*Volume of the cylinder

Volume of the cone = 1/3*Volume of the cylinder, so

Volume of the cylinder=3*Volume of the cone =3*258.9=776.6 cm³

Volume of the cylinder= 776.6 cm³

Answer:

776.7 cm^3

Determine whether the function is linear or quadratic. Identify the quadratic, linear, and constant terms of the equation: y=(x-1)(4x+2)-4x^2

Answers

The specified formula y = (x-1)(4x+2)A linear function, -4x² has a constant term of -2 and a linear term of 2x.

To determine whether the function y = (x-1)(4x+2)-4x^2 is linear or quadratic, we can analyze the equation and identify its terms.

Start with the equation:

y = (x-1)(4x+2)-4x²

Expand the equation by multiplying the terms:

y = 4x² + 2x - 4x - 2 - 4x²

Simplifying further,

y = 2x - 2.

Analyzing the equation, we can see that there is no x² term. This indicates that the function is linear.

Let's identify the terms of the equation:

Quadratic term: There is no x² term in the equation.

Linear term: The linear term is 2x.

Constant term: The constant term is -2.

Therefore, the given function y = (x-1)(4x+2)-4x² is a linear function with a linear term of 2x and a constant term of -2.

Hello,

Multiplying (x-1) by (4x+2) the term in x² is x*4x=4x².
If we substract 4x² the term of y in x² will be 0.
The function is not quadratic.

Since 4x*(-1)+2*x=-2x (product of terms in x) : the function is thus linear.

Constant term is -1*2=-2
