Answers
Answer:4/8 or simplified answer 1/2
Step-by-step explanation:
3/4 + 3/8, first you have to find the highest common factor of 4 and 8.
The answer is 9. The denominator of both side will be 8. Now you ask yourself 4 times what gives you 8 and times the numerator by that number. And do the same for the 8.
6/8 + 3/8= 9/8
9/8 - 5/8= 4/8
The simplified answer is 1/2

Find the volume of the cylinder.
Answers
Answer:
Step-by-step explanation:
V=πr^2h is the equation for volume of a cylinder.
the radius is half of 50 so 50/2=25.
then 75 is the height so you plug the vaules in
V=(3.14)((25)^2)(75)
then multiply and you get 147187.5 rounded to the nearest whole number that is 147188

Place the quadratic y=2x^2+24x+79 into vertex form by using the method of completing the square and then state the coordinates of its vertex.
Answers
Answer:
[tex]y=2(x+6)^2+7[/tex]
[tex](-6,7)[/tex]
Step-by-step explanation:
[tex]y=2x^2+24x+79[/tex]
Completing the square is a process of converting a quadratic equation in standard form into vertex form.
The first step in completing the square is grouping the quadratic and linear terms of the quadratic equation.
[tex]y=(2x^2+24x)+79[/tex]
Factor out the coefficient of the quadratic term,
[tex]y=2(x^2+12x)+79[/tex]
Now complete the square, add a term to make the grouped part of the equation a complete square, then balance the equation.
[tex]y=2(x^2+12x+36-36)+79[/tex]
Simplify,
[tex]y=2(x^2+12x+36)+79+(2)(-36)[/tex]
[tex]y=2(x+6)^2+79-72[/tex]
[tex]y=2(x+6)^2+7[/tex]
The x-coordinate of the vertex of the equation is equal to (-1) times the numerical part of the quadratic term, and the y-coordinate is equal to the constant.

Solve the quadratic equation by factoring.
4x² - 20x + 28 = 3
A) x = 5
B) x = 5/2
C) x = 2/5
D) x = - 5/2
Answers
Answer:
B) x = 5/2
Step-by-step explanation:
subtract 3 from each side to get:
4x² - 20x + 25 = 0
this is the difference of 2 squares:
(2x -5)² = 0
one solution, x = 5/2
Answer:
B) x = 5/2
Step-by-step explanation:
4x² - 20x + 28 = 3
Move terms to the left side
4x² - 20x + 28 - 3 = 0
Subtract the numbers
4x² - 20x + 25 = 0
Use the quadratic formula
[tex]x =\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
4x² - 20x + 25 = 0
a = 4
b = -20
c = 25
x = [tex]\frac{-(-20)+\sqrt{(-20)^{2}-4x4x25 } }{2x4}[/tex]
Evaluate the exponent
x = [tex]\frac{20+\sqrt{400-4x4x25 } }{2x4}[/tex]
Multiply the numbers
x = [tex]\frac{20+\sqrt{400-400 } }{2x4}[/tex]
Subtract the numbers
x = [tex]\frac{20+\sqrt{0} }{2x4}[/tex]
Evaluate the square root
x = [tex]\frac{20+0 }{2x4}[/tex]
Add zero
x = 20 / 2 x 4
Multiply the numbers
x = 20 / 8
Cancel terms that are in both the numerator and denominator
x = 5/2
