Answer:
yes, this is a function because each x value is paired with with exactly one y value (the first one in the multiple choice)
Step-by-step explanation:
For something to be a function an input can have only one output. Multiple different inputs can have the same output, but not the other way around.

If a = 12 in and b = 25 in, what is the area of the pencil? A. 372 in2 B. 169 in2 C. 322 in2 D. 444 in2
Answer:
1169 in^2 Approx
Step-by-step explanation:
Given data
We know that the shape of the pencil is cylindrical
Hence the dimension is
Diameter= 12in
Radius= 12/2= 6in
Height= 25in
The surface area of a cylinder is given as
T.S.A.=2πrh+2πr^2
Substitute
T.S.A.=2*3.142*6*25+2*3.142*6^2
T.S.A.=942.6+226.224
T.S.A=1168.824
Hence the area is 1169 in^2 Approx

Given f(x) = 2x^3+ 9x + k, and x + 1 is a factor of f(x), then what is the value of k?
Answer:
11Step-by-step explanation:
to understand thisyou need to know about:factor theoremtips and formulas:if f(c)=0 then x-c is a factor of f(x)let's solve:according to the question
2(-1)³+9(-1)+k=0
=>2(-1)+9(-1)+k=0
=>-2-9+k=0
=>-11+k
therefore
k=11
Find the percent change. 150 pounds to 135 pounds.
Answer:
-10%
Step-by-step explanation:
precent change = 135 - 150
(divide both sides by 150)
precent change = -0.1
(multiply both sides by 100 so change to precent)
precent change = -10%
Answer:
10%

What number would represent 56 feet below sea level?
Answer:
-56
Step-by-step explanation:
That is because the 56 is below sea level, not above it, so it would be negative 56
Hope that helps!
-56ft
Since it is BELOW sea level it would be considered a negative number. If it were ABOVE sea level then it would be a positive number. Another way to think about this:
Above Sea Level = +
Below Sea Level = -

The height of a right cone is 3 inches shorter than the radius. What is the height of the cone if the volume is 17 cubic inches?
a. 3.454 inches
b. 4.01 inches
c. 7.01 inches
d. 1.01 inches
Answer:
1.03 inches
Step-by-step explanation:
Volume of a come = 1/3πr²h
If the height of a right cone is 3 inches shorter than the radius, then;
h = r - 3
Substitute
V = 1/3πr²(r-3)
Given that V = 17in^3
17 = 1/3πr²(r-3)
17*3 = 3.14r²(r-3)
51/3.14 = r²(r-3)
16.242 = r²(r-3)
r² = 16.242
r = √16.242
r = 4.03
Since h = r - 3
h = 4.03 - 3
h = 1.03 inches
hence the height is 1.03 inches

Hey There!
So the congruency statement ABC = TUV
states that side AB = side TU side BC = side UV and side CA = side VT
The given side lengths are BC and UV which are congruent to each other so we set up an equation to solve for x
7x+2=6x+11
step 1 subtract 2 from each side
2-2 cancels out
11-2=9
Now we have
7x=6x+9
step 2
subtract 6x from each side
7x-6x=x
6x-6x cancels out
now we have 9=x so x=9
Now we just plug in 9 to x in (6x+11)
to find the length of the given side length
6x9=54
54+11=65
Because side VU and side BC are congruent they both equal 65 cm
So we can conclude that the length of the given sides is 65 cm

find the line equation y=mx+b
the slope is =2 and goes through the point (-3,5)
Answer:
y = 2x + 11
Step-by-step explanation:
y = mx + b, m is the slope which we already, it is 2. B is the y-intercept, which we don't know. To find the y-intercept, you plug in the coordinates into the equation so far, which is y = 2x + b.
y = 2x + b
5 = 2(-3) + b
5 = -6 + b
11 = b
So our equation is y = 2x + 11
given the expression -x^2-6x+7,when expressed in form a(x+h)^2+k, the value of k is?
Answer: k = 16
Step-by-step explanation:
The equation is written in the form:
y = ax^2 + bx + c
y = -x^2 - 6x + 7
y = a(x - h)^2 + k where (h, k) is the vertex
a = -1 (from the original equation)
h = -b/2a (this is the equation for the line of symmetry or the x-value of the vertex)
h = -(-6)/2(-1) = 6/-2 = -3
when x = -3, y = ?
y = -(-3)^2 - 6(-3) + 7
y = -(9) + 18 + 7
y = -9 + 18 + 7
y = 16
(-3, 16) is the vertex
Since k is the y-value of the vertex, k = 16
I'll just take it a step further and write the whole equation:
Substitute all the values we found
-1(x +3)^2 + 16
-(x + 3)^2 + 16
