What is the point-slope form of the equation of a line that passes through the point (1, 4) and has a slope of −3?
zmey [24]
So y=mx+b
m=slope

y=-3x+b
subsitutue 1 for x and 4 for  y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b

the equaiton is y=-3x+7

HELP ASAP THIS IS STRESSING ME OUT!
Alex73 [517]
The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.

If the radius of the base is r and the height is h, then the surface area of the cylinder is

A=2\pi r^2+2\pi rh

You're given that the area is 96\pi and the radius is 4, so you have

96\pi=2\pi\times4^2+2\pi\times4h\implies 12=4+h\implies h=8

A rectangle is inscribed in a right isosceles triangle, such that two of its vertices lie on the hypotenuse, and two other on th
Rufina [12.5K]

Answer:

Part 1) The base is 25\ in  and the height is 10\ in

Part 2) The base is 7.5\ in  and the height is 18.75\ in

Step-by-step explanation:

case 1) Right isosceles triangle of the left

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

y+x+y=45

2y+x=45 ----> equation A

\frac{x}{y} =\frac{5}{2}

x=2.5y -----> equation B

substitute equation B in the equation A

2y+2.5y=45

4.5y=45

y=10\ in

Find the value of x

x=2.5(10)=25\ in

case 2) Right isosceles triangle of the right

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

y+x+y=45

2y+x=45 ----> equation A

\frac{y}{x} =\frac{5}{2}

y=2.5x -----> equation B

substitute equation B in the equation A

2(2.5x)+x=45

6x=45

x=7.5\ in

Find the value of y

y=2.5(7.5)=18.75\ in
