What is y=1/2(x+3)^2+10 in standard form

anyanavicka [17]

Answer:

Simplified equation in standard form: $y=\frac{1}{4}x^{2}+12\frac{1}{4}$

Original equation in standard form: $y=1/2(x+3)^2+10$

Step-by-step explanation:

$y=\frac{1}{2}(x+3)^2+10$

Step 1: Distribute the $\frac{1}{2}$ :

$y=(\frac{1}{2}*x+\frac{1}{2}*3)^2+10$

$y=(\frac{1}{2}x+1\frac{1}{2})^2+10$

Step 2: Take $(\frac{1}{2}x+1\frac{1}{2})$ and square it :

$y=(\frac{1}{2}x+1\frac{1}{2})^2+10$

$y=(\frac{1}{2}x)^{2} +(1\frac{1}{2})^2+10$

$y=(\frac{1}{2}x*\frac{1}{2}x)+(1\frac{1}{2}*1\frac{1}{2})+10$

$y=\frac{1}{4}x^{2}+2\frac{1}{4}+10$

Step 3: Add the constants:

$y=\frac{1}{4}x^{2}+(2\frac{1}{4}+10)$

$y=\frac{1}{4}x^{2}+(12\frac{1}{4})$

Step 4: Get rid of the parenthesis:

$y=\frac{1}{4}x^{2}+12\frac{1}{4}$

Solve for in the diagram below.

Sveta_85 [38]

Answer:

x = 20

Step-by-step explanation:

The sum of the three angles in the diagram is 180 degrees since they form a straight line

x + 100 + 3x = 180

Combine like terms

100 +4x = 180

Subtract 100 from each side

100+4x-100 =180-100

4x= 80

Divide each side by 4

4x/4 = 80/4

x = 20

Which of the following are possible measures of the interior angles of a regular polygon? If possible, how many sides does the p

gizmo_the_mogwai [7]

Step-by-step explanation:

180(n-2)/n=90 ( this is the solution for the 90)

cross multiplying

180n-360=90n

180n-90n=360

90n=360

90n/90=360/90

n=4, the number of sides for the polygon with 90° is 4 sides

Solution for 100°

180(n-2)/n=100

180n-360=100n

180n-100n=360

80n=360

80n/80=360/80

n=4.5

Same applies to the rest 110°,125° ,150°,175°
