The table shows the width and length of different pictures that Katie has enlarged for the school yearbook:
Based on the table, what is the length of a picture that has a width of 20 inches?
The table would show:
Width 5 10 15
Length 6 12 18
24 inches
35 inches
38 inches
40 inches
Answer:
24 inches
Step-by-step explanation:
Pattern for the length is time 6.
Do 6 x 4, which will equals 24
Our Answer is- 24 inches.
Another way:
6 - 10 = +6
12 - 18 = +6
18 -24 = +6
Therefore- 18 - 24 = +6
24 Inches
How much will you have in the bank if you invested $500 for four years at 3% interest,
compounded annually?
Answer:
You will have $560 in the bank after 4 years.
Step-by-step explanation:
So we have the principal, rate and the time, we need to find the interest.
All we have to do is multiply the principal by the rate, and then the product of P×R by the time.
But first, we need to convert the rate into a decimal, so:
500 × 0.03 = 15
15 × 4 = 60
F is a function that relates the price of a product to the revenue it will generate. If a price of $5 corresponds to $8,000 in revenue, which of the following correctly shows this relation using function notation?
The function that correctly shows this relation using function notation is f(5) = 8000
Functions are expressions separated by an equal sign. They have both dependent and independent variables.
From the given question, we have that F is a function that relates the price of a product to the revenue. From the statement;
Price is the dependent variable and product of revenue is the independent variable;
Let x be the product of revenue
f(x) be the price
If a price of $5 corresponds to $8,000 in revenue, this can be expressed as:
f(x) = 8000
since x = 5, then f(5) = 8000
Hence the function that correctly shows this relation using function notation is f(5) = 8000

Find the slope:
Hello, there.
To find the slope of a line, first you need to make sure which points this line passes through:
The slope [tex]m[/tex] of a line, passing through the points [tex](x_0,~y_0)[/tex] and [tex](x_1,~y_1)[/tex] is given by the formula [tex]m=\dfrac{y_1-y_0}{x_1-x_0}[/tex].
As we can see in the graph, this lines passes through the points [tex](0,~1)[/tex] and [tex](1,~3)[/tex], such that we can substitute these values on the formula to find its slope:
[tex]m=\dfrac{3-1}{1-0}[/tex]
Subtract the values in both numerator and denominator
[tex]m=\dfrac{2}{1}=2~~\checkmark[/tex]
This is the slope of this line.

The area of a rectangle is 54 square feet. Find the length and width if the length is
three feet less than twice the width
Answer:
Width = 6 ft
Length = 9 ft
Step-by-step explanation:
Width =w
Length = 2w - 3
Area = 54 sq. ft
length *width = 54
(2w -3) *w = 54
2w² - 3w = 54
2w² - 3w - 54= 0
P = -108
Sum = -3
Factors = -12,9 {-12 + 9 = -3 & (-12)*9 = -108}
2w² - 12w + 9w -54 = 0
2w(w - 6) + 9(w- 6)=0
(w-6)(2w + 9) = 0
Ignore (2w + 9) as measure wont be negative
w -6 = 0
w = 6 ft
length = 2*6 - 3 = 12-3 = 9 ft
Describe the relationship between and using geometric terms.
Answer:
Geometric Relationships. Geometric relationships control the orientation of an element with respect to another element or reference plane. For example, you can define a tangent relationship between a line and an arc. If the adjoining elements change, the tangent relationship is maintained between the elements.
What is the slope of the line through (-3, 3) and (-1,-1)?
Answer:
(-2,-4)
Step-by-step explanation:
To find the slope you count down the units on the grid from one point to the other.
Or in this case, -3 minus -1 is -2.
3 minus -1 is -4
Therfore the slope for the line with points (-3, 3) and (-1,-1) is (-2,-4)

Jane invests $5,757 in an account that earns an annual interest rate of 2%. What will be the balance of the account in 16 years if the interest is compounded continuously?
Answer:
C
Hope it helps you, tell me if im wrong pls, be safe :D
The balance of the account in 16 years if the interest is compounded continuously will be $7,599.24.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
It is given that, Jane invests $5,757 in an account that earns an annual interest rate of 2%.
We must first divide "2%" by the principal ($5,757) to get a decimal, which we must then multiply by. So:
5,757 × 0.02 = 115.14
Then we multiply the product of P×R by the time, 16 years. So:
115.14 × 16 = 1,842.24
We now add the principle to our finished product. So:
5,757.00 + 1,842.24 = $7,599.24
Thus, the balance of the account in 16 years if the interest is compounded continuously will be $7,599.24.

The length of one base of a trapezoid is 7mm less than twice the length of the other base. The height of the trapezoid is 12mm. The area of the trapezoid is 48 square mm. Find the length in millimeters of the longer base. (Please show step by step)
Answer:
The length of the longer base is 5mm.
Step-by-step explanation:
The area of a trapezoid:
[tex]A=\frac{1}{2}h(b_1+b_2)[/tex]
With the given information, we can write some equations to represent the problem:
[tex]b_1=2b_2-7\\48=\frac{1}{2}(12)(b_1+b_2)[/tex]
There's only 2 equations and 2 variables, so it's a relatively simple system of equations to solve. Ill solve by substitution:
[tex]b_1=2b_2-7\\48=\frac{1}{2}(12)(b_1+b_2)\\\\48=\frac{1}{2}(12)((2b_2-7)+b_2)\\48=(6)(3b_2-7)\\48=18b_2-42\\18b_2=90\\b_2=5[/tex]
Now, plug that back into the first equation to solve for the other variable:
[tex]b_2=5\\b_1=2b_2-7\\\\b_1=2(5)-7\\b_1=10-7\\b_1=3[/tex]
Now we have the measures of both of the bases.
the longer base = 5mmthe shorter base = 3mmTo check that, calculate the area using these bases:
[tex]A=\frac{1}{2}(12)(3+5)\\A=6(8)\\A=48[/tex]
It works fine.

Answer:
the slope is -5/3
Step-by-step explanation:
Find slope of the line using the formula: slope= difference between vertical changes / difference between horizontal changes= (-9-1) / 2-(-4) = -10/6=-5/3
Answer:
19) slope = undefined
20) slope = [tex]\mathsf{-\frac{5}{3} }[/tex]
Step-by-step explanation:
19) Graph of a vertical lineGiven the graph of a vertical line, with coordinates of (-2, 3) and (-2, -3):
Since the formula for solving the slope of a line is given by:
[tex]\mathsf{m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]
This implies that a vertical line has no horizontal change. Therefore, the value of the denominator in the given formula will be: x₂ - x₁ = 0. This division by zero is an undefined operation, hence the slope of a vertical line is undefined.
20) Find the slope of a line through the given pair of points.
Given the coordinates, (2, -9) and (-4, 1), substitute these values into the following slope formula:
[tex]\mathsf{m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]
Let (x₁, y₁) = (2, -9)
(x₂, y₂) = (-4, 1)
Substitute these values into the given formula:
[tex]\mathsf{m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]
[tex]\mathsf{m = \frac {1\: -\: (-9)}{-4\: -\:2}\:=\:\frac {1\: +\:9}{-6}\:=\:\frac{10}{-6}\:=\:-\frac{5}{3}}[/tex]
Therefore, the slope of the line is, [tex]\mathsf{m\:=\:-\frac{5}{3} }[/tex].

Answer:
