Hello!
I believe the answers are:
A) The vertex is (1, −6)
C) The graph has a minimum.
I hope it helps!
Move the decimal point to the right one place value.
1.7 x 10 = 17
17 is your answer
hope this helps
Answer:
C
Step-by-step explanation:
the question is asking for the difference between the two values, therfore, you should subtract the smaller value from the larger value
while A is technically the same equation, when finding a value, you want all the constants to be on 1 side of the equation while the variable is on the other side
4a-13=19 add 13 to both sides
4a=32 divide by 4 on both sides
a=8
We know that the area of a circle in terms of π will be πr². However the area with respect to the diameter will be a different story. The first step here is to find a function relating the area and diameter of any circle --- ( 1 )
For any circle the diameter is 2 times the radius,
d = 2r
Therefore r = d / 2, which gives us the following formula through substitution.
A = π(d / 2)² = πd² / 4
<u>Hence the area of a circle as the function of it's diameter is A = πd² / 4. You can also say f(d) = πd² / 4.</u>
Now we can substitute " d " as 4, solving for the area ( A ) or f(4) --- ( 2 )
f(4) = π(4)² / 4 = 16π / 4 = 4π - <u>This makes the area of circle present with a diameter of 4 inches, 4π.</u>
