Find the x-intercepts of the parabola with vertex (1,-108) and y-intercept (0,-105). Write your answer in this form: (X1,y1), (x

Stolb23 [73]

Answer:

(7, 0) and (-5, 0)

Step-by-step explanation:

<u>Vertex form</u>

$y=a(x-h)^2+k$

(where (h, k) is the vertex)

Given:

vertex = (1, -108)

$\implies y=a(x-1)^2-108$

Given:

y-intercept = (0, -105)

$\implies a(0-1)^2-108=-105$

$\implies a(-1)^2=-105+108$

$\implies a=3$

Therefore:

$\implies y=3(x-1)^2-108$

The x-intercepts are when y = 0

$\implies 3(x-1)^2-108=0$

$\implies 3(x-1)^2=108$

$\implies (x-1)^2=36$

$\implies x-1=\pm \sqrt{36}$

$\implies x=1\pm 6$

$\implies x=7, x=-5$

Therefore, the x-intercepts are (7, 0) and (-5, 0)

What's a squared plus a squared

ad-work [718]

for example lets use 3^2 + 4^2, you add the main numbers, 3 and 4 to get 7, then there are still the exponents, the squared signs, they don't change, they stay as a two. If your problem required a single whole number, then you have to square the 7, 7*7 is 49, so that or 7^2 would be your final answer.

Answer:

Step-by-step explanation:

180+148+xy=360

xy=32

arc=32=double the angle=16 degrees

Since both are radii they are equal. It is an isoceles triangle so angle x equals angle y.

180=16=164/2=82
