Answer:
At least 6 students must be enrolled in the class for the instructor to make a profit.
At least 20 students must be enrolled in the class for the instructor to make $1,000 (or more) profit per month.
Step-by-step explanation:
The function 
models the profit of the instructor of a guitar class per month.
1. If the instructor makes a profit, then
So, at least 6 students must be enrolled in the class for the instructor to make a profit.
2. If the instructor needs to make 1,000.00 profit per month, then
So, at least 20 students must be enrolled in the class for the instructor to make $1,000 (or more) profit per month.
Take all the variables and put them next to each other but still in order.
Keep their negatives and positives.
6x-2x-9x 5y+3y
Do the math with the variables that way, and you'll get an answer of
-5x 8y
Reform them into the simplified equation, so you'll end up with an equation of
-5x+8y
The x would be before the y since that's how it is in the alphabet. That would be a simplified form of the equation.
Answer:
7+y
Step-by-step explanation:
Answer:
The answer is 40°
Step-by-step explanation:
Solution
Now,
The Measure of major arc FD = 280°
Thus,
One complete angle measure 360°
Then
m∠FED = 360 - 180
m∠FED = 80°
Thus,
FE = DE ( the same circle Radius)
∠EFD = ∠EDF ( opposite angles to equal sides are equal)
Now
Applying angle sum property of a triangle in ΔEFD
∠EFD + ∠EDF + ∠FED = 180°
∠EFD + ∠EFD + 80 = 180
2∠EFD = 100
∠EFD = 50°
Hence, GF is tangent to the circle and the tangent always make right angles with the radius of the circle.
∠EFG = 90°
∠GFD + ∠EFD = 90°
∠GFD + 50 = 90
∠GFD = 40°
Therefore, The measure of the angle GFD is 40°
The correct answer is B)
.
The denominator of the exponent is the root we are taking. The numerator is the exponent of the radicand. This means 3 will be the denominator, since it is a cubed root, and 2 will be the numerator of m while 5 will be the numerator of n.
