how do you use scientific notation to estimate the hours in a year
Answer:
8.760 x 10^3
Step-by-step explanation:
There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.
Hope this helps! :)

Thats how you do it
Answer:
x=6
Step-by-step explanation:
first you have to subtract 4 from both sides
3x=2x+10-4
then simplify 2x+10-4 to 2x+6 so you will get
3x=2x+6
-2 -2
(^^you subtract 2x from both sides )
then you get your answer which is x=6

If your talking about how much they are going to pay ONLY interest for two years then it is $1,479. $1,479 is the amount of money they will be paying for two years ONLY FOR INTEREST.

3% of 24,650 is 739.5. That is for one year. 739.5 times 2 for two years is 1,479. Just in interest they will be paying a total of 1479 for two years. Let me know if I'm right. This should be right though. Hope it helped :)

Round 545 to the nearest hundred
Answer:
500
Step-by-step explanation:
Answer:
500
When rounding to the nearest hundred, like we did with 545 we use these rules
first you would have to round the number up to the nearest hundred if the last two digits in the number are 50 or above.
then you would have to round the number down to the nearest hundred if the last two digits in the number are 49 or below.
lastly you would have to see if the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

What is the vertex of this parabola? y= 2x² + 4x +5
Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )
