Answer:
Option D.
Step-by-step explanation:
It is given that, graph of j(x) transformed in the graph of j(4x) – 27.
We need to find the transformations.
Consider the new function is
[tex]f(x)=j(4x)-27[/tex] ... (1)
The translation is defined as
[tex]f(x)=j(kx+a)+b[/tex] ... (2)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph stretched horizontally by factor of 1/k and if k>1, then the graph compressed horizontally by factor of 1/k.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
k=4>1, the graph j(x) compressed horizontally by factor of 1/4.
a=0, so there is no horizontal shift.
b=-27<0, so the graph of j(x) shifts 27 units down.
So, the required transformations are horizontal compression by a factor of 1/4, and a translation 27 units down.
Therefore, the correct option is D.
Answer:
D) horizontal compression by a factor of 1/4, and a translation 27 units down

6-4x=7x-9x+8 What is the answer to my question
Answer:
-1
Step-by-step explanation:
We have our expression
6 - 4x = 7x - 9x + 8
Combine like terms
6 - 4x = -2x + 8
Add 2x to both sides, and subtract 6 from both sides
-2x = 2
x = -1
Answer:
-2x − 2 = 0 is the answer to this

This question is not complete
Complete Question
A boat sails 4km on a bearing of 038 degree and then 5km on a bearing of 067 degree.(a)how far is the boat from its starting point.(b) calculate the bearing of the boat from its starting point
Answer:
a)8.717km
b) 54.146°
Step-by-step explanation:
(a)how far is the boat from its starting point.
We solve this question using resultant vectors
= (Rcos θ, Rsinθ + Rcos θ, Rsinθ)
Where
Rcos θ = x
Rsinθ = y
= (4cos38,4sin38) + (5cos67,5sin67)
= (3.152, 2.4626) + (1.9536, 4.6025)
= (5.1056, 7.065)
x = 5.1056
y = 7.065
Distance = √x² + y²
= √(5.1056²+ 7.065²)
= √75.98137636
= √8.7167296826
Approximately = 8.717 km
Therefore, the boat is 8.717km its starting point.
(b)calculate the bearing of the boat from its starting point.
The bearing of the boat is calculated using
tan θ = y/x
tan θ = 7.065/5.1056
θ = arc tan (7.065/5.1056)
= 54.145828196°
θ ≈ 54.146°

. Every month, there are 1000 independent TIE fighter flights, and each TIE fighter flight crashes with a probability of 0.0035. (a) What is the probability that at least 2 crashes occur in the next month
Answer:
[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]
Step-by-step explanation:
From the information given:
The probability that at least 2 crashes occurs in the next month can be estimated by using Poisson distribution because the sample size is large and the probability of the event p = 0.0035 is rare.
∴
Let X be the random variable that follows a Poisson distribution
The probability that at least 2 crashes occurs in the next month is:
[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]
A chord is 15 cm long. It is 9 cm from the center of the circle. What is the radius of the circle?
Answer:
11.72cmStep-by-step explanation:
Given a chord of distance of 15cm, if it is 9cm from the center of a circle, this means that the 9cm length will be projecting from the centre of the circle perpendicular to the chord and passing through its centre.
Since the radius of a circle is a line that is drawn from the centre of a circle to ts circumference, the set up will form a right angles triangle within the circle with the hypotenuse as the radius and the other two sides as the opposite and adjacent respectively. Using the Pythagoras theorem to get the length of the radius (hypotenuse);
hyp² = opp² + adj²
Let the opposite be the 9cm length
Adjacent will be half of the chord length = 15/2 = 7.5cm
Substituting this values into the formula we will have;
hyp² = 9² + 7.5²
hyp² = 81+56.25
hyp² = 137.25
hyp² = √137.25
hyp = 11.72
Hence the radius of the circle is approximately 11.72 cm long

Converting it to decimal makes it easier to work with. It might make be an extra step, but in the long run of the problem it helps to make calculations accurate and easier to solve by working with simpler numbers. Converting to decimal form makes the number more precise for square roots, which are usually not whole numbers.
Samantha conjectures that for x < - 1 it is true that x ^ 5 - 2 > x her conjecture correct? Why or why not?
Answer:
Her conjecture is not correct
Step-by-step explanation:
Given
[tex]x^5 - 2 > x[/tex]
For [tex]x < -1[/tex]
Required
Determine if the conjecture is true
[tex]x < -1[/tex] implies that the values of x are:
-2, -3, -4, -5.....
Take any value of x and substitute in [tex]x^5 - 2 > x[/tex]
Let x = -3
[tex]x^5 - 2 > x[/tex] becomes
[tex]-3^5 - 2 > -3[/tex]
[tex]-243 - 2 > -3[/tex]
[tex]-245 > -3[/tex]
The above inequality is false;
Hence:
Her conjecture is not correct
Write the slope-intercept form of the equation of the line through the given point with the given slope. through: (3,1). slope= 4/3
Answer:
y = 4/3x - 3
Step-by-step explanation:
Use the slope intercept equation, y = mx + b, where m is the slope and b is the y intercept:
Plug in the point given and the slope to find b:
y = mx + b
1 = 4/3(3) + b
1 = 4 + b
-3 = b
Then, plug this and the slope into the equation:
y = 4/3x - 3 will be the equation

Find the angle between the vectors a = (4, 2, -4) and b = (4, -3, 2).
SOLUTION Since
lal = 42 + 22 + (-4)2 =
and
[b] = V 42 + (-3)2 + 22 = V 29
and since
a. b = (4)( 14 ) + (2)(-3) + (-4)(2 )
we have from this corollary
COS = a.b |а|
|Ь| | 89 So the angle between a and b is as follows. (Round your final answer to two decimal places.) 0 = cos-10 29 89 x rad
Answer:
86.45°Step-by-step explanation:
Given two vectors a = (4, 2, -4) and b = (4, -3, 2), the formula to be used to calculate the angles between both vectors is as expressed below;
[tex]a.b = |a||b| cos \theta[/tex] where [tex]\theta[/tex] is the angle between both vectors
a.b = (4, 2, -4). (4, -3, 2)
a.b = 4(4)+2(-3)+2(-4)
a.b = 16-6-8
a.b = 16-14
a.b = 2
Given |r| = √x²+y²+z²
|a| = √4²+2²+(-4)²
|a| = √16+4+16
|a| = √36
|a| = 6
Similarly;
|b| = √4²+(-3)²+2²
|b| = √16+9+4
|b| = √29
Substituting the parameters gotten into the formula to get the angle between the two vectors a and b we will have;
[tex]a.b = |a||b| cos \theta\\2 = 6*\sqrt{29} \ cos \theta\\ cos\theta = \dfrac{2}{6\sqrt{29} } \\cos\theta = \dfrac{1}{3\sqrt{29} }\\ cos\theta = 0.0619\\\theta = cos ^{-1}0.0619\\ \theta = 86.45^0 (to \ 2dp)[/tex]
Hence the angle between vectors a and b is 86.45°

Answer:
752.95
Step-by-step explanation:
Data provided in the question
The standard deviation of population = 210
The Margin of error = 15
The confidence level is 75%, so the z value is 1.96
Now the required sample size is
[tex]= 1.96^2\times \frac{210^2}{15^2}[/tex]

Is there a smallest decimal that is greater than the number 2? Explain your answer.
Answer:
Technically, yes. It's called epsilon, which is defined as an infinitely small number. So
2 + epsilon is the smallest number greater than 2. But for practical purposes no there isn't.
00
Step-by-step explanation:Not without limits. You can always move the .1 one place further from the interring. For example,
2.1>2.01
and
2.01>2.001
So, unless there are a limited number of decimal spaces, you can continually add an infinite amount of zeros behind the decimal point, followed by a one.
If you use two or three decimal spaces as a standard in your class, then the smallest decimal greater than 2 would be 2.01 or 2.001, respectively.
4(100,000,000) + 3(10,000,000) + 2(100,000) + 9(10,000) + 1(100)

Complete Question
CoStar would like to test if the vacancy rate for "warehouse" stores is more than 8%. A type 1 error would occur if CoStar concludes that the vacancy rate was
A: not equal to 8% when, in reality, the proportion was equal to 8%
B: 8% or less when, in reality, the proportion was more than 8%
C: equal to 8% when, in reality, the proportion was 8% or less
D: more than 8% when, in reality, the proportion was 8% or less
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
CoStar would like to test if the vacancy rate for "warehouse" stores is more than 8%.
Hence
The null hypothesis is [tex]H_o : p \le 0.08[/tex]
The alternative hypothesis is [tex]H_a : p> 0.08[/tex]
Generally type 1 error occurs when null hypothesis is rejected while it is true
So Type I error would occur if CoStar concludes that the vacancy rate was more than 8% when, in reality, the proportion was 8% or less

1: find the value of 8 4s. It’s not 84 but it’s 8 and then at the top it’s 4.
2: a mug is 1/7 full. The mug contains 1/3 of a cup of water. Find the capacity of the mug. Write the answer a fraction or mixed number in simplest form.
Problem 1
If you meant to say [tex]8^4[/tex], then you would have four copies of 8 multiplied together
[tex]8^4 = 8*8*8*8 = 4096[/tex]
==============================================
Problem 2
1/7 full = 1/3 cup of water
7*(1/7 full) = 7*(1/3 cup of water) ... multiply both sides by 7
1 full = 7/3 cup of water
So a full mug has 7/3 cups of water. Let's convert this to a mixed number
7/3 = (6+1)/3
7/3 = 6/3 + 1/3
7/3 = 2 + (1/3)
7/3 = 2 & 1/3
The full capacity of the cup is 7/3 cups or 2 & 1/3 cups
7/3 is the improper fraction form
2 & 1/3 is the mixed number form
One way to think of it is to imagine there are 7 cookies and you want to distribute among 3 friends. We could say 7/3 = 2 remainder 1 meaning each person gets 2 full cookies and there's 1 left over. So that's how we'd get 2 & 1/3.

Bicycles are often on sale in September. The regular price of one bicycle is $181.95. With a 20% discount, what is the sale price of the bicycle? Round to the nearest cent(hundredths).
Answer:
sale price = $145.56
Step-by-step explanation:
The regular price of one bicycle is $181.95
20% discount
sale price = original price - ( % discount x original price )
sale price = $181.95 - (0.20 * $181.95)
sale price = $181.95 - $36.39
sale price = $145.56
