I'm rounding number to the nearest hundredth like 6.271 is 6.371 right

1 answer:

7 0

No<u> it will be 6.27 </u>as the hundredth column is the second after the decimal place. To work out what to round it to look at the number after the hundredth column and if it is between 1 and 4, round down by just taking the number off like this, or if it is 5 to 9 round up the hundredth column by adding one to the number e.g. 5.578 would round up to 5.58.

(5x+3)(7x-7) how do find x

Delvig [45]

We can use the FOIL method to solve.

(5x + 3)(7x - 7)

(5x * 7x) + (5x * -7) + (3 * 7x) + (3 * -7)

35x - 35x + 21x - 21

0 + 0

Best of Luck!

Y= -x^2+2x+1 <br>i need help understanding

Eddi Din [679]

Answer:

Does not factor; domain = -∞<x<∞, range = f(x) ≤ 2.

Step-by-step explanation:

Assuming your end goal is to factor the polynomial

$y=-x^{2} +2x+1$

If we use the guess and check method we can see that there is no way to factor this polynomial.

However, if you are looking for a domain and range we can graph it on a graphing calculator. Just by looking at the graph, we can see that the domain is all real numbers, or -∞<x<∞, and the range is f(x) ≤ 2.

I hope this helped!

Help i dont know the formula for the triangle to find the answer its surface area n volume

777dan777 [17]

Answer:

#4=10.5

#5=48

Step-by-step explanation:

The formula for the triangle for area is 1/2 time base times hight

The forumale fot the triangle for volume is 1/2 time base times hight

So for number #4 it will be 1/2 x 3 x 7

and number #5, it will be 1/2 x 8 x 12

The parents organization bought 1,000 bumper stickers at $1.25 each to sell at football games.They want to make at least $750 pr

yuradex [85]

1000 x 1.25 = 1250
1000 x 2 = 2000
2000 - 1250 = 750
2000 divided by 1000 = 2

They should sell the bumper stickers for $2 each.
Hope this helped =)
