On Monday Anders read for a quarter hour if he and crazy amount of time he read by seven minutes each day how many hours would he have red by Friday

By Friday he would have read for 145 hours.

Step-by-step explanation:

Given:

Number of hours Anders read on Monday =15 minutes

Every day he increases the reading time by 7 minutes

This reading time forms an arithmetic progression

Here,

The first value is "a"=15

Common difference "d"=7

Number of days from Monday to Friday =5, Thus n=5

Number of minutes he read by Friday=sum up to 5 terms of the AP=S5

Number of times he read on Friday =a5

Thus By Friday he would have read for 145 hours.

i really dont know

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
