Which is the 30o-60o-right triangle theorem?

1 answer:

3 0

A 30 60 90 triangle is when one angle is 30, another is 60 and the other one is 90. and the side across from the 30 is x(1) and the one across from 60 is x rote 3(rote 3) and across from 90 is 2x(2).

Answer:

8.9

Step-by-step explanation:

The answer is 8.9 because two negatives divided by each other equals a positive. In this case, there are two negatives so you know the answer will be a positive. In the end when you divided –65.86 ÷ (–7.4), you get 8.9!

Create a cubic function that is not the parent function.

salantis [7]

Answer:

Below.

Step-by-step explanation:

One is (x - 3)^3.

The graph of the parent function x^3 rises from the lower left quadrant and there is a point of inflection through (0, 0), then it rises to the right in the first quadrant.

The graph of (x - 3)^3 is the translation of the graph of x^3, 3 units to the right. It will pass through the x-axis at (3, 0).

Hi there! The answer is 5/6 hours (which is 50 minutes)

To find the total time Ann spent on her papers, we must add the fractions.
$\frac{1}{3} + \frac{1}{2} = \frac{2}{6} + \frac{3}{6} = \frac{5}{6}$

In the first step, we had to make the denominators the same. We need to use the LCM of the numbers 2 and 3. LCM(2,3) = 6.

In the second step we added the fractions. Remember that we only need to add the numerators (the denominator remains the same).

~ Hope this helps you!

Can someone help figure out how to solve this equation? Thank you!

We will use the binomial coefficient formula to work out the answer

The formula is given by:
$^nC_r= \left(\begin{array}{ccc}n\\r\end{array}\right)= \frac{n!}{(n-r)!r!}$
Where:
'n' is the total population or sample population
'r' is the number of pick

We have:
n = 20
r = 3
Substitute these values into the formula we have
$^{20}C_3= \frac{20!}{(20-3)!3!}=1140$

Answer:
There are 1140 different ways of picking three winners out of 20 people
