Answer:
Step-by-step explanation:
Slope of line passing through (0, 3) and (3, -1) = (-1-3)/(3-0) = -4/3
Slope of any parallel to the line is also -4/3.
Point-slope equation for line of slope -4/3 that passes through (-3, 2):
y-2 = (-4/3)(x+3)

Nadia's class took a math test. The median score on the test was 72% and the mean of the test scores was 72%.
What does this tell you about the data set?
The data shows causation.
The data is accurate.
The data is symmetrical.
Answer:
C, or "The data is symmetrically"
Step-by-step explanation:
This is because when having both the median and the mean the same, this means their is a perfectly symmetrical distribution of data. Making both the mean and median the same.

Here is an expression: 2 + 3ⁱ ( Remember what you do when you replace i with a number) Evaluate the expression when i is 1.
Answer:
The value of the expression when i is 1 is equals to 5.
Step-by-step explanation:
We are given the following expression:
[tex]2 + 3^{i}[/tex]
Evaluate the expression when i is 1.
We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So
[tex]2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5[/tex]
The value of the expression when i is 1 is equals to 5.

Which trigonometric expression is to equal to the ratio 12/13 in the right triangle?
A. tan X
B. cos X
C. tan W
D. cos W
Answer:
[tex]\Huge\boxed{D}[/tex]
Step-by-step explanation:
Hello There!
To find the answer we want to find the trigonometric ratio for each answer choice
important note;
[tex]sin =\frac{opposite}{hypotenuse} \\\\cos=\frac{adjacent}{hypotenuse} \\\\tan=\frac{opposite}{adjacent}[/tex]
for A,
the opposite of angle X is 12 and the adjacent of angle x is 5
so [tex]tanX=\frac{12}{5}[/tex] therefore A is not the answer
for B,
the adjacent of angle x is 5 and the hypotenuse is 13
so [tex]cosX=\frac{5}{13}[/tex] therefore B is not the answer
for C,
the opposite of angle W is 5 and the adjacent of angle W is 12
so [tex]tanW=\frac{5}{12}[/tex] therefore C is not your answer
for D,
the adjacent of angle W is 12 and the hypotenuse is 13
so [tex]cosW=\frac{12}{13}[/tex] therefore D is your answer

Answer:
4. 300 5. 7 6. 2
Step-by-step explanation:
In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:
[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]
We would then cross multiply in order to find the value of x. Like this:
60 × 5 = 300
1 × x = 1x
300 = 1x
300 = x
So now we know that x is 300.
We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:
[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]
8 × x = 8x
2 × 28 = 56
8x = 56
÷8 ÷8
x = 7
We now know that x is 7.
Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!
A company makes Poppy Lapel Pins.
Each of them costs £1.30 to make.
In October it made 800 lapel pins.
25% of them are given to charities.
The rest are sold in two formats: 70% of them at £2.50 each
30% of them at £5.00 for 3
Assuming that all the lapel pins will be sold by the end of November,
work out the percentage profit the company should make.
Give your answer to 1 decimal place.
Please someone help it may have been answered before but it's hard to change the values at a certain stage. Thanks
Answer:
29.8%
Step-by-step explanation:
1.30 × 800 = £1040
25% of 800 = 200
800 - 200 = 600 poppy lapel pins given to the charity
70% of 600 = 420
420 × 2.50 = £1050
30% of 600 = 180
180÷3 = 60
60 × 5.00 = £300
[tex]\frac{1050+300-1040}{1040}[/tex] = 29.8076923
= 29.8% to one decimal place
I hope I helped :)
The company should make a percentage profit of approximately 29.8%.
Given that a company makes Poppy Lapel Pins.
Each of them costs £1.30 to make.
In October 800 lapel pins were made from which 25% were given to charities,
The rest are sold in two formats:
70% of them at £2.50 each
30% of them at £5.00 for 3.
We need to find the percentage profit the company should make.
To calculate the percentage profit, we first need to determine the total cost of manufacturing the lapel pins and the total revenue generated from their sales.
Total Cost:
Cost per lapel pin = £1.30
Number of lapel pins manufactured = 800
Total cost = £1.30 × 800 = £1040
Total Revenue:
Number of lapel pins given to charities = 25% of 800 = 0.25 × 800 = 200
Number of lapel pins available for sale = 800 - 200 = 600
Format 1:
70% of lapel pins sold at £2.50 each:
Number of lapel pins = 0.70 × 600 = 420
Revenue from this format = £2.50 × 420 = £1050
Format 2:
30% of lapel pins sold at £5.00 for 3:
Number of lapel pins = 0.30 × 600 = 180
Revenue from this format = (£5.00 ÷ 3) × 180 = £300
Total Revenue = Revenue from Format 1 + Revenue from Format 2 = £1050 + £300 = £1350
Profit:
Profit = Total Revenue - Total Cost = £1350 - £1040 = £310
Percentage Profit:
Percentage Profit = (Profit ÷ Total Cost) × 100
Percentage Profit = (£310 ÷ £1040) × 100 ≈ 29.8%
Therefore, the company should make a percentage profit of approximately 29.8%.

12years ago Justin Timberlake put money into an account paying 6.5% interest compounded biannually. If the account has $18,000 now, how much money did Justin Timberlake deposit?
Answer:
$8645.73
Step-by-step explanation:
Using the compound interest formula :
A = P(1 + r/n)^nt
A = final amount = 18000
r = rate = 6.5% = 0.065
n = number of compounding tines per period, biannually, once in 2 years = 0.5
18000 = P(1 + 0.065/0.5)^(0.5*12)
18000 = P(1 + 0.13)^6
18000 = P(2.081951752609)
18000 / 2.081951752609 = P
= 8645.7334
= $8645.73

Factorise j out of both terms on the left side.
j (j-30) = 0
Apply zero product rule.
j = 0 or j-30 = 0
Find the value of j.

A. -1 < x < 6
B. -1 < y = 6
C. -2 < x < 5
D. -1 3y = 6
Answer:
Option A is the correct answer
Step-by-step explanation:
[tex] - 1 \leqslant x \leqslant 6[/tex]
The domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a given a graph of a function in the picture.
As we can see, the at point x = -1 graph starts, and it has dark dot which means function values exist at x = -1.
Similarly, at x = 6 the function value exist.
The domain of the function:
-1 ≤ x ≤ 6
Thus, the domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.

Give your answer as a decimal.
Therefore , the solution of the given problem of triangle comes out to be triangle C has the largest area 4.5 square unit.
What precisely is a triangle?Because a triangular has two or more extra parts, it is a polygon. It's shape is a simple rectangular. The only three edges that distinguish a triangle from just a triangle are A, B, and C. A singular area rather than a cube is produced by Euclidean geometry when the edges are not perfectly collinear. A shape is referred to as triangular if it has three sides and three angles. An angle is the point where a quadrilateral's three sides meet. A triangle's sides add up to 180 degrees.
Here,
The largest triangle ,
area wise is:
Triangle C area is:
=> 1/2 * b * h
=> 1/2 * 3*3
=> 9/2
=> 4.5 square unit
which is the largest area as all the other triangles have 4 square unit area.

Answer:
The series of transformations that apply are a vertical compression by a factor of 2 and a translation of 4 units down.
Step-by-step explanation:
In a slope-intercept function, the coefficient of the variable determines whether the graph opens up or down, as well as the amount it stretches. If a function's coefficient is greater than 1, as the value of the coefficient increases, the function becomes more vertically compressed. If a function's coefficient is less than 1 but greater than 0, as the coefficient gradually approaches 0, the function becomes more vertically stretched. Since the function's coefficient went from 1 to 2, that means the graph of the function is being vertically compressed by a factor of 2. A slope-intercept function's constant is the graph's y-intercept since the y-value would be that when x is equal to 0. Since the constant went from 0 to -4, that means the graph of the function has been translated down 4 units. So the correct choices would be a vertical compression by a factor of 2, and a translation of 4 units down.
