The answer is C
5.76 x 10 ^3 means you move the decimal 3 times:
57.6> 576.0> 5760
Answer:
The answer is 68 and 52
Step-by-step explanation:
x + y = 120
3(x - y ) = 48
We have 3x + 3y = 360
and 3x - 3y = 48
Adding we have the following:
6x = 408
x = 68
y = 120-48 = 52
Answer:
2.99 x 10⁸ meters per second
Step-by-step explanation:
Scientific notation (also called "Standard form") is written in the form of
, where
and
is any positive or negative whole number.
To <u>convert</u> a number into <u>scientific notation</u>, move the decimal point to the left or right until there is <u>one digit before the decimal point.</u>
The number of times you have moved the decimal point is the power of 10 (
).
If the decimal point has moved to the <u>left</u>, the power is <u>positive</u>.
If the decimal point has moved to the <u>right</u>, the power is <u>negative</u>.
<u>To convert the given number to scientific notation</u>
The decimal point for the given number 299000000 is after the last zero:
⇒ 299000000.
Move the decimal point 8 places to the left:
⇒ 2.99000000
Get rid of the redundant zeros:
⇒ 2.99
Multiply by 10 to the power of the number of decimal places moved:
⇒ 2.99 x 10⁸
Therefore, the speed of light using scientific notation is:
- 2.99 x 10⁸ meters per second
1. Arrange all the terms containing y on the left side and all other terms on the right hand side.
-y = -x^2 + 6x - 8
2. Complete the square on the right side of the equation.
(x-3)^2 - 1
3. Reorder the right side of the equation to match the vertex form of a parabola.
4. Use the vertex form, y = a(x - y)^2 + k, to determine the values of a, h, and k.
a = 1, h = 3, k = -1
5. Find the vertex (h, k).
(3, -1)
