Mathematics

Mumz [18]3 years ago

Answer:

Step-by-step explanation:

The base of the cylinder is in the shape of a circle:

Area of the base=\pi *r^2

For Base area=22 square units

22=\pi *r^2

      22=3.14*r^2\\r^2=22/3.14\\r^2=7.01\\r=\sqrt{7.01}

Volume of the cylinder=\pi *r^2*h

For volume '198 cubic units' the height(h) is:

       198=\pi *r^2*h

       198=3.14*(\sqrt{7.01})^2*h

         198=3.14*7.01*h\\\\198=22.01*h\\\\198/22.01=h\\\\h=9 units\\

For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y
mariarad [96]

Answer:

Table A

Step-by-step explanation:

y  = 3x^2 +2x -8

The quadratic is in the form

y = a x^2 +bx+c

a = 3  b = 2 c = -8

Since a > 0 it opens up

The y intercept is c so the y intercept is -8

How much longer is the hypotenuse of the triangle than its shorter leg?
Nastasia [14]
We can use the Pythagorean Theorem to solve for side AB
a^2+b^2=c^2
a will be 6 and b will be 8 becuase those are the legs

6^2+8^2=c^2
36+64=c^2
100=c^2 (square root both sides)
c=10

Then we find the difference between 10 and 6 because 6 is the shortest leg
10-6=4 ft. so B

Hope this helps
