to calculate percent increase use
× 100%
increase = $650 - $525 = $125
percent increase = × 100% = 24% → B
Zach is running 5 miles an hour.
Using division we can do 7 1/2 / 1 1/2 we would get 5.
Answer:
Step-by-step explanation:
When comparing to standard form of a parabola:
Vertex form of a parabola is: , which is what we are trying to convert this quadratic equation into.
To do so, we can start by finding "h" in the original vertex form of a parabola. This can be found by using: .
Substitute in -8 for b and 2 for a.
Simplify this fraction.
The "h" value is 2. Now we can find the "k" value by substituting in 2 for x into the given quadratic equation.
Simplify.
We have the values of h and k for the original vertex form, so now we can plug these into the original vertex form. We already know a from the beginning (it is 2).
The given expression is:
Now, we know that the square of 1.1 is 1.21, which means that 1.1 multiplied by itself gives 1.21.
Mathematically, that can be expressed as:
or,
thus, the square root of 1.21 is 1.1
or
Thus, applying this in the expression in the question given to us, we will get:
Thus, 6.7 is the final answer for the given expression.
Answer:
1/2
Step-by-step explanation:
1/3 equals 2/6
