Answer:
A
Step-by-step explanation:
When doing function behaviors it would be really helpful if you memorized the picture i've attached below
We can see that we have a negative leading coefficent and an odd degree which means that as x approaches -∞ it's positive and as x approaches ∞ it's negative
This means that the answer is A
Write the ratios for sin X, cos X, and tan X. Use the / for a fraction.
Answer:
Step-by-step explanation:
From the right triangle attached in the picture,
sine ratio for the angle X,
[tex]\text{sinX}=\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]=\frac{YZ}{XZ}[/tex]
[tex]=\frac{21}{29}[/tex]
cosine ratio for the angle X,
[tex]\text{cosX}=\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]=\frac{XY}{XZ}[/tex]
[tex]=\frac{20}{29}[/tex]
tang ratio for the angle X,
[tex]\text{tanX}=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
[tex]=\frac{21}{20}[/tex]
Write an explicit formula for the An, and the n^th term of the sequence 24,-12,6,....
Answer:
[tex]T_n = -48* (-\frac{1}{2})^{n}[/tex]
Step-by-step explanation:
Given
[tex]24, -12, 6,...[/tex]
Required
Write a formula
The above sequence shows a geometric sequence because:
[tex]r = \frac{-12}{24} = \frac{6}{-12} = -\frac{1}{2}[/tex] -- common ratio
The equation is determined using:
[tex]T_n = ar^{n-1}[/tex]
Where
[tex]a = 24[/tex]
Substitute values for a and r
[tex]T_n = 24* (-\frac{1}{2})^{n-1}[/tex]
Apply law of indices:
[tex]T_n = 24* (-\frac{1}{2})^{n} * (-\frac{1}{2})^{-1}[/tex]
[tex]T_n = 24* (-\frac{1}{2})^{n} * 1/(-\frac{1}{2})[/tex]
[tex]T_n = 24* (-\frac{1}{2})^{n} * 1*-2[/tex]
[tex]T_n = 1*-2*24* (-\frac{1}{2})^{n}[/tex]
[tex]T_n = -48* (-\frac{1}{2})^{n}[/tex]
The above represents the explicit formula

Answer:
1.5 white and 2 blue is an equivalent ratio
Step-by-step explanation:
Which expression is equivalent to (2x + 6) - (3x + 4)
A. -1x + (10)
B. 5x + (10)
C. -1x + (2)
D.5x + (-2)
Answer:
C. -1x + (2)
Step-by-step explanation:
(2x + 6) - (3x + 4)
= 2x + 6 -3x - 4
= 2x - 3x + 6 - 4
= -1x +2
Answer:
C
Step-by-step explanation:
Expand the brackets = 2x + 6 - 3x - 4
Take 3x from 2x to get -1x
The equation is now -1x + 6 - 4
Take 4 from 6 to get 2
The equation is now -1x + 2, which is equal to option C

Suppose X has an exponential distribution with mean equal to 11. Determine the following: (a) (Round your answer to 3 decimal places.) (b) (Round your answer to 3 decimal places.) (c) (Round your answer to 3 decimal places.) (d) Find the value of x such that . (Round your answer to 2 decimal places.)
Answer:
[tex]P(X > 11) = 0.368[/tex]
[tex]P(X > 22) = 0.135[/tex]
[tex]P(X > 33) = 0.050[/tex]
[tex]x = 33[/tex]
Step-by-step explanation:
Given
[tex]E(x) = 11[/tex] --- Mean
Required (Missing from the question)
[tex](a)\ P(X>11)[/tex]
[tex](b)\ P(X>22)[/tex]
[tex](c)\ P(X>33)[/tex]
(d) x such that [tex]P(X <x)=0.95[/tex]
In an exponential distribution:
[tex]f(x) = \lambda e^{-\lambda x}, x \ge 0[/tex] --- the pdf
[tex]F(x) = 1 - e^{-\lambda x}, x \ge 0[/tex] --- the cdf
[tex]P(X > x) = 1 - F(x)[/tex]
In the above equations:
[tex]\lambda = \frac{1}{E(x)}[/tex]
Substitute 11 for E(x)
[tex]\lambda = \frac{1}{11}[/tex]
Now, we solve (a) to (d) as follows:
Solving (a): P(X>11)
[tex]P(X > 11) = 1 - F(11)[/tex]
Substitute 11 for x in [tex]F(x) = 1 - e^{-\lambda x}[/tex]
[tex]P(X > 11) = 1 - (1 - e^{-\frac{1}{11}* 11})[/tex]
[tex]P(X > 11) = 1 - (1 - e^{-\frac{11}{11}})[/tex]
[tex]P(X > 11) = 1 - (1 - e^{-1})[/tex]
Remove bracket
[tex]P(X > 11) = 1 - 1 + e^{-1}[/tex]
[tex]P(X > 11) = e^{-1}[/tex]
[tex]P(X > 11) = 0.368[/tex]
Solving (b): P(X>22)
[tex]P(X > 22) = 1 - F(22)[/tex]
Substitute 22 for x in [tex]F(x) = 1 - e^{-\lambda x}[/tex]
[tex]P(X > 22) = 1 - (1 - e^{-\frac{1}{11}* 22})[/tex]
[tex]P(X > 22) = 1 - (1 - e^{-\frac{22}{11}})[/tex]
[tex]P(X > 22) = 1 - (1 - e^{-2})[/tex]
Remove bracket
[tex]P(X > 22) = 1 - 1 + e^{-2}[/tex]
[tex]P(X > 22) = e^{-2}[/tex]
[tex]P(X > 22) = 0.135[/tex]
Solving (c): P(X>33)
[tex]P(X > 33) = 1 - F(33)[/tex]
Substitute 33 for x in [tex]F(x) = 1 - e^{-\lambda x}[/tex]
[tex]P(X > 33) = 1 - (1 - e^{-\frac{1}{11}* 33})[/tex]
[tex]P(X > 33) = 1 - (1 - e^{-\frac{33}{11}})[/tex]
[tex]P(X > 33) = 1 - (1 - e^{-3})[/tex]
Remove bracket
[tex]P(X > 33) = 1 - 1 + e^{-3}[/tex]
[tex]P(X > 33) = e^{-3}[/tex]
[tex]P(X > 33) = 0.050[/tex]
Solving (d): x when [tex]P(X <x)=0.95[/tex]
Here, we make use of:
[tex]P(X<x) = F(x)[/tex]
Substitute [tex]F(x) = 1 - e^{-\lambda x}[/tex]
[tex]P(X<x) = 1 - e^{-\lambda x}[/tex]
So, we have:
[tex]0.95 = 1 - e^{-\lambda x}[/tex]
Subtract 1 from both sides
[tex]0.95 -1= 1-1 - e^{-\lambda x}[/tex]
[tex]-0.05=- e^{-\lambda x}[/tex]
Reorder the equation
[tex]e^{-\lambda x} = 0.05[/tex]
Substitute 1/11 for [tex]\lambda[/tex]
[tex]e^{-\frac{1}{11} x} = 0.05[/tex]
Solve for x:
[tex]x = -\frac{1}{1/11}\ ln(0.05)[/tex]
[tex]x = -11\ ln(0.05)[/tex]
[tex]x = 32.9530550091[/tex]
[tex]x = 33[/tex] --- approximated

The Browns scored 13 more points than the Saints. The total of
their scores was 47. How many points did each team score?
Answer:
Saints team scores points = 17
Browns team scores point = 30
Step-by-step explanation:
Let Saints team scores points = x
Browns team scores point = y
As given,
The Browns scored 13 more points than the Saints.
⇒ y = x + 13
Now, given
The total of their scores was 47.
⇒ x + y = 47
⇒x + x + 13 = 47
⇒ 2x = 47 - 13
⇒2x = 34
⇒x= [tex]\frac{34}{2}[/tex] = 17
∴ we get
Saints team scores points = x = 17
Browns team scores point = y = x + 13 = 17 + 13 = 30
Answer:
30 , 17
Step-by-step explanation:
browns have x + 13
saints have y
x+13 + x+y = 47
2x = 34
x=17
17 + y = 47
y=30

Fred went to an arcade to play video games. He paid $2 for every 11 tokens he bought. He spent a total of $16 on tokens. Which equation can be used to determine t, the number of tokens Fred bought?
Answer:
D
Step-by-step explanation:
Since there are two types of values here: tokens and dollars, we will need to use the same value across numerators and denominators in the ratio.
Choice D has 11 tokens over $2 equals to t tokens over $16. In both fractions the numerator is tokens and denominator is dollars.

Answer:
Option (D)
Step-by-step explanation:
Given expression is,
x³ × 3 ÷ [tex]\frac{2}{9}[/tex] + 9x - (7 - 6x)
By substituting x = [tex]\frac{2}{3}[/tex],
[tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-6(\frac{2}{3})][/tex]
By using rule PEMDAS,
P - Parenthesis
E - Exponent
M - Multiplication
D - Division
A - Addition
S - Subtraction
[tex]=(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-4][/tex]
= [tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-3[/tex]
= [tex]\frac{8}{27}\times 3 \div \frac{2}{9}+6-3[/tex]
= [tex]\frac{8}{9}\div \frac{2}{9}+6-3[/tex]
= [tex]\frac{8}{9}\times \frac{9}{2}+6-3[/tex]

Two functions are defined by these equations: f(x) = 5.1 + 0.8x g(x) = 3.4 + 1.2x Which function has a greater value when x is 3.9? How much greater?
Step-by-step explanation:
Two functions are defined by these equations:
f(x) = 5.1 + 0.8x
g(x) = 3.4 + 1.2x
Put x = 3.9 in both f(x) and g(x).
f(x) = 5.1 + 0.8(3.9)
= 8.22
g(x) = 3.4 + 1.2(3.9)
= 8.08
So, f(x) is greater than g(x).
f(x)-g(x) = 8.22 - 8.08
= 0.14
So, f(x) is 0.14 units more than g(x).

7. Washcloths were selling for $1.88 each. If 14 1/4 dozen cloths were sold, what was the retail value of the total sales
Answer:
The retail value of the total sales was $311.48
Step-by-step explanation:
14 1/4 dozen cloths were sold
This means that the total number of cloths sold was:
[tex]14*12 + 12*\frac{1}{4} = 168 + 3 = 171[/tex]
Each for $1.88
So the retail value of total sales was.
$1.88*171 = $311.48
The retail value of the total sales was $311.48
