The equation of a parabola is the following:

(y - k) = a(x - h)^{2}

where (h, k) is the coordinate of the vertex and a is a constant. With the information you have above, you are able to fill in (h, k) and solve for a with the information that (1, 0) and (5, 0) are roots of the equation.

The average smoker typically pays 15% higher life insurance costs than the average non-smoker. If the monthly cost to a non-smok
Maksim231197 [3]

Answer:

$75

Step-by-step explanation:

The average smoker pay 15% life insurance than the non-smoker

The monthly cost of a non-smoker is $500 per month

Therefore the amount that would be paid by the average smoker in a month can be calculated as follows

= 500 × 15/100

= 500 × 0.15

= 75

Hence the amount to be paid is $75

What is the equation of a line whose slope is 2 and passes through the point (-6,9)
yuradex [85]

Answer:

y = 2x + 21

Step-by-step explanation:

Step 1: Write out known variables

y = mx + b

m = 2

y = 2x + b

Step 2: Find <em>b</em>

9 = 2(-6) + b

9 = -12 + b

b = 21

Step 3: Rewrite linear equation

y = 2x + 21

How do you know which number is the largest when you compare integers?
Nady [450]

Answer:

Step-by-step explanation:

Lets take 4905 and 802

Firstly to figure out which of these two numbers is bigger we first look at the highest place value that either one of these two numbers have

In this case its 4 in the thousands place in the number 4905

Next we look at which number 802 has in the thousands place

In this case there is no number or 0

4 is bigger than 0 so we know that 4905 is bigger than 802

Lets take another example

4905 and 8204

Here both numbers have a number in the thousands place on is 8 and the other is 4

8 is bigger than 4 so 8204 must be larger

I'm just saying comparing integers should come very easily and you really don't need to think much to figure this out

I'm guessing you mean how do you compare numbers which are non-integers like 4/6 or  4/5  and this is quite easy

There are multiple ways but one method is to just multiply the denominator of one fraction with the numerator of the other and do the same for the other fraction

lets take 4/6 and 4/5

4*5=20

and 4*6= 24

4/6 we can assign 20

and 4/5 is 24

the bigger number is 24 so 4/5 is bigger
