Answer:

m∠3 = 63°

Step-by-step explanation:

Linear pair: If in adjacent angles, the non common arms form a line, then they are called linear pair.

∠1 + ∠5 = 180 {linear pair}

117 + ∠5 = 180

∠5= 180 - 117

∠5 = 63°

If l₁ // l₂, then alternate interior angles should be congruent.

∠3 = ∠5

∠3 = 63°

The function below is written in vertex form or intercept form. Rewrite them in standard form and show your work.

lora16 [44]

Answer:

The standard form as $y=5x^2+30x+41$

Step-by-step explanation:

Given: A function which is written in vertex form or intercept form.

We have to re-write it in standard form that in terms of

Given $y = 5(x+3)^2-4$

Squaring using $(a+b)^2=a^2+b^2+2ab$ , we get,

$y=5(x^2+9+6x)-4$

Multiply 5 inside , we get,

$y=5x^2+45+30x-4$

Solving further , we get,

$y=5x^2+30x+41$

Thus , we have obtained the standard form as $y=5x^2+30x+41$
