Answer:
B. False
Step-by-step explanation:
According to pythagorean theorem, for this to be a right triangle, the sum of square of the length of the two legs must equal square of the length of the hypotenuse (longest side).
So 
should equal 
- <em>We also know that
</em>
Hence, 
, and
They ARE NOT EQUAL, so the triangle is NOT a right triangle.
Answer:
You can do 60 ÷ 6 = 10 groups.
Step-by-step explanation:
There are many ways to answer this and it's very simple.
6 and 10 is just one of the many factors of 60.
you can also do 60 ÷ 2 = 30 groups
Answer:
The temperature on Celsius scale for 86 ºF is 30 ºC.
Step-by-step explanation:
Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:
(1)
Where:
- Temperature, measured in degrees Fahrenheit.
- Temperature, measured in degrees Celsius.
If we know that 
, then its equivalent temperature on Celsius scale is:
The temperature on Celsius scale for 86 ºF is 30 ºC.
Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is
<span>x = a(y - k)^2 + h </span>
<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>
<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>
