Is AB a tangent to the circle
From the attached circle, we can see that AP is the radius of the circle P.
And by definition, a tangent touches the circle at only one point.
Since AB touches the circle at only point A, then AB is a tangent.
Answer:
They sold 120 milkshakes that day
Step-by-step explanation:
We can set up a proportion
48 × 5 = 2m
2m = 240
m = 120
Note: If you have some value, , and it is of the total amount, you can find the value by doing the equation
Answer:
120 into a third and divide and the answer
Step-by-step explanation:
160
Answer:
x^3 + 9x^3 -6x -54
Step-by-step explanation:
first step is you're going to simplify the problem.
using the (a-b)(a+b)=a^2-b^2 formula combine the last two grouped numbers to equal (x+9)(x^2-6)
multiply the parenthesis to get x^3 - 6x + 9x^2 -54
reorder the terms and then you get your answer! x^3 + 9x^3 -6x -54
does this make sense? :)
Answer:
g(- 4) = - 32
Step-by-step explanation:
substitute x = 4 , g(4) = - 4 into g(x)
4a + b = - 4 → (1)
substitute x = 6 , g(6) = 3 into g(x)
6a + b = 3 → (2)
subtract (1) from (2) term by term to eliminate b
2a + 0 = 3 - (- 4)
2a = 3 + 4 = 7 ( divide both sides by 2 )
a = 3.5
substitute a = 3.5 into (1) and solve for b
4(3.5) + b = - 4
14 + b = - 4 ( subtract 14 from both sides )
b = - 18
Then
g(x) = 3.5x - 18 , so
g(- 4) = 3.5(- 4) - 18 = - 14 - 18 = - 32
