Answer:
Option A = 113.04in^2
Step-by-step explanation:
Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.
A) 113.04 in.2
B) 100.48 in.2
C) 131.88 in.2
D) 69.08 in.2
Solution:
Total surface area of a cylinder = 2πr^2 + 2πrh
r = radius = 2in
h = height = 7in
Let π = 3.14
Total surface area of the cylinder =
2×π×2^2 + 2×π×2×7
= 8π + π×28
= 8×3.14 + 3.14×28
Total surface area of the cylinder = 113.04in^2
=113.04in^2 (option A)
Is the question mark + or -. If it’s plus the answer would be 16 if it’s minus the answer would be 10.
Answer:
Look below.
Hopefully they're right.
Step-by-step explanation:
1. m=3/1 b=6
2. m=5/6 b=-5
3. m=-3/4 b=1
The following are the answers to
the questions presented:
Part 1:
Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>
Axis of
symmetry = x = -3/2
Domain = all
real numbers
Range = <span>y </span><span>≤ </span>11/2
Part 2:
A quadratic equation is symmetrical around its vertex. The
equation for the axis of symmetry is x = -3/2 since the equation is in terms of
x. Since no value of x is undefined, then the domain of the equation is clearly
all real numbers. Since the value of “a” is negative, then that means the y
coordinate of the vertex is the maximum value so the range will never get above
11/2. I am hoping that these answers have satisfied your queries and it
will be able to help you in your endeavors, and if you would like, feel free to

Answer:
y=x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-4)/(4-2)
m=2/2
m=1
y-y1=m(x-x1)
y-4=1(x-2)
y=x-2+4
y=x+2
