Answer:
Step-by-step explanation:
The domain is all possible values for x.
The range is all possible values for f(x) or y.
The domain given is {-3, -2, -1, 1}.
Plug x as {-3, -2, -1, 1} and find the f(x) or y values.
The range is {7, 6, 5, 3}, when the domain is {-3, -2, -1, 1}.
Answer:
54
Step-by-step explanation:
To solve this, you have to find the area of the square then the area of the triangle, and add them together.
To find the are of a square you multiply the base by the height.
Example: 6 × 6 = 36
To find the area of a triangle you multiply the base by the height and divide it by 2.
Example: 6 × 6 = 36
36 ÷ 2 = 18
Now we add both areas together.
Example: 36 + 18 = 54
Answer:
f=1/x^2-81
Step-by-step explanation:
Step 1: Multiply both sides by x^2-81.
fx3−81fx=x
Step 2: Factor out variable f.
f(x3−81x)=x
Step 3: Divide both sides by x^3-81x.
f(x3−81x)
x3−81x
=x
x3−81x
f=
1
x2−81
First you need to divide 220/10 to see how many bagles they make an hour.
220/10=22
Then you Multiply 22*13 and you get 286.
So they make 286 bagels in 13 hours.
Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.
