Answer:
Yes
Step-by-step explanation:
Graphs are functions when there is only one output for every input. In other words, for every "x" value, there must be only "y" value. This graph depicts a function because it abides by this rule. To be exact, this is an exponential function with the formula: f(x) = (x + 2)².
So, let's say the number is x.
5(x + 27) ≥ 6( x + 26)
Answer:
0.2986 (29.86%)
Step-by-step explanation:
cup volume = πr²H = 3.14 x 4² x 7 = 351.68 cm³
after 3 minutes (70 /2) x 3 =105 cm³
the percent of the cup that is filled 105/351.68 = 0.2986 (29.86%)
The answer is A. (-2,-3)
You can use your graphing calculator and go to Matrix and edit. Then plug in the values and next, go to rref and find the values.
Area of a circle = (pi)(radius squared)
Find the area of the larger circle, then find the area of the smaller circle and then subtract the difference.
Larger Circle:
A=(3.142)(5cm)2
A=(3.142)(25)
A=78.55
Smaller Circle:
A=(3.142)(2)2
A=(3.142)(4)
A=12.57
Subtract difference between the 2:
78.55-12.57= 65.98 cm is the area of the shaded portion
