For the quadratic function <img src="https://tex.z-dn.net/?f=y%3D%28x%2B4%29%5E2-1" id="TexFormula1" title="y=(x+4)^2-1" alt="y=

Answer:

$y=x^2+8x+15$

Intercept form is y= (x+5)(x+3)

vertex is (-4,1)

y intercept is (0,15)

x intercepts are (-5,0) (-3,0)

Step-by-step explanation:

Given quadratic function

$y=(x+4)^2-1$

To rewrite it in standard form we need to expand (x+4)^2

$y=(x+4)(x+4)-1$

$y=x^2+8x+16-1$

$y=x^2+8x+15$

Intercept form is y=a(x-p)(x-q)

Factor x^2 + 8x + 15

product is 15 and sum is 8, 5*3= 15 and 5+3=8

(x+5)(x+3)

Intercept form is y= (x+5)(x+3)

Vertex form of equation is y=(x-h)^2+k

where (h,k) is the vertex

$y=(x+4)^2-1$ , here h = -4 and k =1 so vertex is (-4,1)

To find y intercept plug in 0 for x

y= (x+5)(x+3)

y= (0+5)(0+3) = 15, so y intercept is (0,15)

to find x intercept plug in 0 for y

y= (x+5)(x+3)

0= (x+5)(x+3), x+5 =0 and x+3=0

x=-5 and x= -3

So x intercepts are (-5,0) (-3,0)

Can someone helpppp plssss

Leokris [45]

Answer:

angleQ+angleR is 180degrees because of the properties of isoceles trapezoid. So, if you set equation and solve, you'll get the fact that x is 12, and angleR is 130degrees, and angleQ is 50degrees. According to the properties of isoceles trapezoid, angleQ is the same as angleT. So, angleT is 50degrees

Can someone help me with this question please.

Answer:

6, 8, and 10.

Step-by-step explanation:

You could work this out with the pythagorean theorem, by proving that 6^2, 36, plus 8^2, 64, equals 100. The fastest way, however, is to use pythagorean triples. These are predetermined sets of numbers that work as side lengths for right triangles. The first two are 3, 4, and 5, which form a right triangle, and 6, 8, and 10, shown here.
