Answer:

the awnser is c

Step-by-step explanation:

A- 100:1 would mean it is a 10000% markup

B- 1:100 lower than b so eliminate

C- 2:1 So a is double the amount of b so it's 100%

D- 1:2 B is 100% of a so it's flipped, not what question is asking for

So process of elimination shows that C is the correct awnser

What is the axis of h(x) = 5x^2+40x+64

zepelin [54]

H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4

Hernando and Rachel are factoring 2mp-6p+27-9m. Is either of them correct? Explain your reasoning,

vichka [17]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as Hernando and Rachel's solution are not provided. So, I will just solve the question directly.

Given

$2mp-6p+27-9m$

Required

Factor

$2mp-6p+27-9m$

Group into 2

$2mp-6p+27-9m = [2mp-6p]+[27-9m]$

Factor each group

$2mp-6p+27-9m = 2p[m-3]+9[3-m]$

Rewrite 3 - m as -(m-3)

So, we have:

$2mp-6p+27-9m = 2p[m-3]-9[m-3]$

Factor out m - 3

$2mp-6p+27-9m = [2p-9][m-3]$

PLEASE HELPPPP I DONT KNOW HOW TO DO THIS

KonstantinChe [14]

Answer:

I'm not an expert here, this is a best guess!

But I would say if there is no chance that of him incurring excess costs of less than $500, then he knows without insurance he'll end up paying at least $500, possibly more out of pocket, without the insurance.

so I would say He ends up spending the least amount out if pocket by going with option A. for $75. that's $75 out of pocket with no deductible and it covers his $500+ in excess costs....B and C would also cover the excess, but would each cost $140 or $275 out of pocket at the end of the day....

with that being said, I'd say it's worth it to buy the insurance....even if he doesn't have any excess costs, he's spent $75 dollars for the peace of mind to know he's covered either way, and if he does incur the excess costs he's spent $75 rather that $500+....Even if the excess charges are only $100, which it says there is no chance of happening, but still, then he's still saved $25 altogether. Unless I'm reading it wrong, Option A saves him the most money either way, and is worth it to buy the insurance!

HELP 30 POINTS!!!!!

Tamiku [17]

by pythagorean formula, the last side is √(61)

by cos rule

cos A

$= \frac{ {6}^{2} + 61 - {5}^{2} }{2 \times 6 \times \sqrt{61} } \\ = \frac{72}{12 \sqrt{61} } \\ = \frac{6}{ \sqrt{61} }$

A = 39.81
