{a, b, c, d, e, f}
A.100
B.120
C.240
D.30
Answer:
B 120 different combinations
Step-by-step explanation:
There are 6 letters to choose from
Picking a letter for the first spot 6
Then there are 5 letters left
Picking a letter for the second spot 5
Then there are 4 letters left
Picking a letter for the second spot 4
6*5*4
= 120

You know that the sum of all of the angles in a triangle must be equal to 180º, we can make an equation.
55º + 67.5º + 3xº + 14º = 180º
Combine like terms:
136.50º+ 3xº = 180º
Subtract 136.50º
3xº = 180º - 136.50º
3xº = 43.50º
Divide by 3
xº = 43.50º / 3º
x = 14.50º

Which of the following could be the equation of the function below?
On a coordinate plane, a curve crosses the y-axis at y = negative 1.5. It has a maximum at negative 1.5 and a minimum at negative 2.5. It goes through 2 cycles at pi.
y = 0.5 cosine (2 (x minus StartFraction pi Over 2 EndFraction)) + 2
y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2
y = 0.5 cosine (4 (x + pi)) + 2
y = 0.5 cosine (2 (x minus pi)) minus 2
Answer:
y = 0.5 cosine (4 (x - pi/2)) - 2
Step-by-step explanation:
Taking the general form:
y = A cosine (Bx - Cπ)) + D
In the following case. the constants are:
y = 0.5 cosine (4x - 2π)) - 2
A: 0.5
B: 4
C: 2π
D: -2
The range of this function is:
range = [-|A|+D, |A|+D]
range = [-0.5-2, 0.5-2]
range = [-2.5, -1.5]
Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"
At x = 0, the function value is:
y = 0.5 cosine (4(0) - 2π)) - 2
y = 0.5 - 2 = -1.5
As indicated in "a curve crosses the y-axis at y = negative 1.5"
The period of the function is:
period: 2π/B
period = 2π/4 = π/2 or 2 cycles at π
as described in "It goes through 2 cycles at pi."
Answer:
B) y = 0.5 cosine (4 (x minus StartFraction pi Over 2 EndFraction)) minus 2
Explanation:
Hope you have a great day!
Find the zeros of the function. Write the smaller solution first, and the larger solution second. f ( x ) = ( x − 1 ) 2 − 36
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x

"Just look at the graph," the player's agent said. "Phil's hits have doubled since last year. We are looking for a large raise
and a long contract."
Look at the graph
Phil's Hits
Thisyear
Last year
100 120 140 160 180 200
Is the agent's claim misleading? Why or why not?
a. No, the top line is twice the length of the bottom line showing that Phil has doubled his number of
hits
b. Yes, although one line is twice the length of the other, it does not show twice the number of hits.
c. Yes, the horizontal scale does not have uniform increments starting with zero.
d. Both b and c.
Answer:

The relationship is additive because
the number of gallons can be found by
adding 5 to the number of minutes.
»
The relationship is multiplicative
because the number of gallons can be
found by multiplying the number of
minutes by 8.
The relationship is multiplicative
because the number of minutes can
be found by multiplying the number of
gallons by 8.
Answer:
(C)The relationship is multiplicative because the number of gallons can be
found by multiplying the number of minutes by 8.
Step-by-step explanation:
Given the table below which shows the relationship between the number of minutes that a hose has been on and the number of gallons of water that have been added to a plastic pool.
[tex]\left|\begin{array}{c|c}$Minutes Hose On&$Gallons of Water in Pool\\-------&-------\\0&0\\5&40\\10&80\\15&120\\20&160\end{array}\right|[/tex]
We can see that if we multiply the first column by 8, we will obtain the second column. Therefore the relationship is multiplicative because the number of gallons can be found by multiplying the number of minutes by 8.
The correct option is C.
What is the length of the hypotenuse
Answer:
15ft
Step-by-step explanation:
a^2 + b^2 = c^2
12 or 9 can equal to b or a
12^2 + 9^2 = c^2
144 + 81 = c ^2
225 = c^2
Square root of 225
15 = c
Answer:
15
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 12^2 = c^2
81+144 = c^2
225 = c^2
15 = c
The points (-16,r) and (-4,11)lie on a line with slope 1/2. Find the missing coordinate r?
Answer: The missing coordinate R is 5.
Step-by-step explanation:
11=1/2(-4) + B
11=-2 +B
B= 13
B represents the y-intercept
so we will use the equation y=mx + B and we know the slope and y intercept.
r= 1/2(-16) + 13
r= 5

A weight is attached to a spring which moves up and down as a function of time
plt) uves the position of the weight at time (t). Position is in centimeters and time is in seconds
Complete the following sentences based on the graph of the function,
• The graph is a nonlinear function
• The initial position of the weight is centimeters
• The weight first reaches equilibrium Whent = seconds)
Note: We say that the weight is at equilibrium whenever plt) = 0 cm, and we say that the initial position of the block
is its position when t = 0

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).
What is the perimeter of rectangle ABCD?
_____units
Answer:
The perimeter of rectangle ABCD = 16 units
Step-by-step explanation:
The vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).
AB is horizontal, so measre the difference between the x coordinates of A and B.
between -2 and 3 are 5 units.
BC is vertical, so measre the difference between the y coordinates of B and C.
between 4 and 1 is 3 units.
The perimeter = 2 * ( AB + BC )
Substitute AB = 5 and CD = 3
2 * ( 5 + 3 )
2 * 8
The perimeter of rectangle ABCD = 16 units
Answer:
16 units

What is the value of x in the equation.
2/3(1/2x+12)=1/2(1/3x+14)-3?
A:-24
B:-6
C:-2/3
D:0
Answer:
A
Step-by-step explanation:
Our equation is:
[tex]\frac{2}{3} *(\frac{1}{2} x+12)=\frac{1}{2} *(\frac{1}{3} x+14)-3[/tex]
Let's first distribute the left side. When distributing, we essentially find the sum of the product of the outside term with each of the inside terms. Here, the outside term is 2/3 and the inside terms are 1/2x and 12. So:
[tex]\frac{2}{3} *(\frac{1}{2} x+12)=\frac{2}{3} *\frac{1}{2} x+\frac{2}{3} *12=\frac{1}{3} x+8[/tex]
Now distribute the right side. Here, the outside term is 1/2 and the inside terms are 1/3x and 14, so:
[tex]\frac{1}{2} *(\frac{1}{3} x+14)-3[/tex]
[tex]\frac{1}{2} *(\frac{1}{3} x+14)-3=\frac{1}{2} *\frac{1}{3} x+\frac{1}{2} *14-3=\frac{1}{6} x+7-3=\frac{1}{6} x+4[/tex]
We now have:
[tex]\frac{1}{3} x+8=\frac{1}{6} x+4[/tex]
Isolate the variable by bringing 1/6x to the left and bringing 8 to the right:
[tex]\frac{1}{3} x-\frac{1}{6} x=4-8[/tex]
[tex]\frac{2}{6} x-\frac{1}{6} x=-4[/tex]
[tex]\frac{1}{6} x=-4[/tex]
x = -4 * 6 = -24
The answer is A.
Steps to solve:
2/3(1/2x + 12) = 1/2(1/3x + 14) - 3
~Distribute
1/3x + 8 = 1/6x + 7 - 3
~Combine like terms
1/3x + 8 = 1/6x + 4
~Subtract 1/6x to both sides
1/3x + 8 - 1/6x = 1/6x + 4 - 1/6x
~Simplify
1/6x + 8 = 4
~Subtract 8 to both sides
1/6x + 8 - 8 = 4 - 8
~Simplify
1/6x = -4
~Multiply 6 to both sides
1/6x * 6 = -4 * 6
~Simplify
x = -24
