<u>Answer:</u>
0 ≤ x ≤ π
<u>Step-by-step explanation:</u>
In order to define the inverse cosine functions, the domains of the cosine functions are restricted.
One major condition to define an inverse of a function is that the original function must be one‐to‐one which means that one value from the domain should correspond to only one value in the range.
So we have a restriction that is placed on the values of the domain of the cosine function which is the following:
0 ≤ x ≤ π
The point slope equation would be one of the equations with -10 in front because it multiplies into x as the negative 10 slope. That narrows it down to C and D. Then the points show 1 and 4 and it has to be positive. That narrows it down the answer D. If this is right could you possibly give me brainliest? Hope this helped.
That is really hard to see
Answer:
fred had 58 marbles
Step-by-step explanation:
peter= x marbles
Fred= x²-6
together= 66 marbles
(x²-6) +x=66
x=8
Fred had 58 marbles
Q= quarts of strawberries.
You have to solve for q by balancing the equation. 2.50 is really being multiplied by 2.50, so you would divide it on the other side for the quart of strawberries.
<em>Balance the equation. </em>
2.50q=10
Divide both sides by 2.50.
2.50(/2.50)q= 10(/2.50)
q=4
There are 4 <em>quarts of strawberries. </em><em>
