Additional comment
For parallel lines in general, all of the obtuse angles are congruent, and all of the acute angles are congruent. All of the obtuse angles are supplementary to the acute angles. (In (7), all angles are right angles, so all are congruent.) These facts can help you with problems like this one.
Learning the language (names/relationships) of these angles will be helpful to you in the future.

An older person is three years older than eight times the age of a younger person. The sum of their age is 21. Find their ages.
Answers
Lets have the younger person be x.
The older person will be 8x + 3.
The sum of their ages is 21, so we can get this equation:
x + (8x+3) = 21
9x+3 = 21
Subtract 3 from both sides
9x = 21
x=3 --> The younger person is 3 years old, and now we can substitute that for the older person (8x+3):
(3 * 8) + 3 = 27
The younger person is 3 years old, and the older person is 27.

A function is defined as an operation on a number, which gives only one output for every input
while graphing a function, the x-ordinate denotes the input and the y-ordinate denotes the output of the function
Now, lets look at the graph

Since there are multiple outputs for almost every input, this graph cannot denote a function since a function gives only one output

The design of a building that has a square pyramid roof as a roof is shown. The cost of material for the outside of the building and for the roof
ranges from $25 per square foot to $50 per square foot. The budget for this material is $500,000. The rectangular front of the building has a
length twice as long as its height. The slant height of the roof is the same as the height of the rectangular front of the building.
What is the maximum possible length of the rectangular front of the building to the nearest foot?
feet
The maximum possible length of the rectangular front of the building is
Answers
The maximum length of the rectangular front is the highest length of the rectangular front, and the value is 128.1 feet
How to determine the maximum possible length?Let the dimension of the rectangular front be x and y.
Such that:
y = 2x
So, the area of the rectangular front is:
A = xy
[tex]A = 2x^2[/tex]
The surface area of the pyramid roof is:
A = 4bh
Where:
b = base =25
h = height =18
So, we have:
[tex]A = 4* 25 * 18[/tex]
[tex]A = 1800[/tex]
The total surface area of the figure is:
[tex]T = 1800 +2x^2[/tex]
The range of the cost of material is: $25 per square foot to $50 per square foot.
So, the maximum cost is:
[tex]50 * (1800 +2x^2) = 500000[/tex]
Divide both sides by 50
[tex]1800 +2x^2 = 10000[/tex]
Subtract 1800 from both sides
[tex]2x^2 = 8200[/tex]
Divide both sides by 2
[tex]x^2 = 4100[/tex]
Take the square root of both sides
x = 64.03
Recall that:
y = 2x
So, we have:
y = 2 * 64.03
y = 128.06
Approximate
y = 128.1
Hence, the maximum possible length of the rectangular front of the building is 128.1 feet

21:35 simplifies to 3:5 when divided by 7 on both sides
24:40 also simplifies to 3:5 when divided by 8 on both sides
Hope that helps!
Answer:
Yes. The are equivalent to each other
Step-by-step explanation:
21 : 35
The LCM of these two numbers is 7
When we divide both of them by 7, we're left with 3:5
24 : 40
The LCM of these two numbers is 8
When we divide both numbers by 8, we're left with 3:5
And, 3:5 = 3:5, so we can say 21:35 = 24:40
PS: Also, if we multiply 21 : 35 by 8 and 24 : 40 by 7, we get the same result, i.e 168 : 280 which also proves that they are equivalent.

Applying the product rule gives

Use the fundamental theorem of calculus to compute the remaining derivatives.

The remaining integrals are
[tex]\displaystyle \int_1^{\ln(x)}\frac{dt}{(1+t)^2} = -\frac1{1+t}\bigg|_1^{\ln(x)} = \frac12-\frac1{1+\ln(x)}[/tex]
[tex]\displaystyle \int_1^{x^2}\frac{2t}{1+t^2}\,dt=\int_1^{x^2}\frac{d(1+t^2)}{1+t^2}=\ln|1+t^2|\bigg|_1^{x^2}=\ln(1+x^4)-\ln(2) = \ln\left(\frac{1+x^4}2\right)[/tex]
and so the overall derivative is
[tex]\displaystyle \frac{4x^3}{1+x^4} \left(\frac12-\frac1{1+\ln(x)}\right) + \frac{1}{x(1+\ln(x))^2} \ln\left(\frac{1+x^4}2\right)[/tex]

find the equation of a line that is parallel to this line and passes through the point (-3,1)
Answers
Answer:
Two possible equations:
Point-slope form is [tex]y-1=-\frac{2}{3} (x+3)[/tex]
Slope-Intercept form is [tex]y=-\frac{2}{3}x+-1[/tex]
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope([tex]m[/tex]).
Then, we need to know the slope-intercept form of an equation. The point slope form is [tex]y-y1=m(x-x1)[/tex] where [tex]m[/tex] is the slope of the line and [tex]y1[/tex] and [tex]x1[/tex] represent the point on the graph. This is the equation we'll use for the line.
So now that we understand what we need to find, we need to find the slope of the existing line. To do this we use the equation [tex]m=\frac{y2-y1}{x2-x1}[/tex]. We can plug in the points (-2,3) and (1,1) on the graph to get [tex]m=\frac{1-3}{1+2}[/tex]. When we simplify this we get [tex]m=-\frac{2}{3}[/tex] so we know our slope is [tex]-\frac{2}{3}[/tex]. Lastly, all we need to do is plug the slope and the new point into our point slope equation to get [tex]y-1=-\frac{2}{3} (x+3)[/tex].
If you needed to go further and put this into slope-intercept form, you could solve the equation for y to get [tex]y=-\frac{2}{3}x+-1[/tex]

Find the values of x and y if:
4x - 2y= -4 and y = 2/3x + 8/3
Answers
Answer: x = 3/4; y = 19/6
Step-by-step explanation:
plug in y = 2/3x + 8/3 into 4x - 2y = -4
4x - 2(2/3x + 8/3) = -4
4x - 4/3x - 18/3 = -4
12/3x - 4/3x = -12/3 + 18/3
8/3x = 6/3
8/3x = 2
x = 2(3/8)
x = 6/8 = 3/4
plug the x value into y = 2/3x + 8/3
y = 2/3(3/4) + 8/3
y = 1/2 + 8/3
y = 3/6 + 16/6
y = 19/6
3.) Susie picks strawberries on her uncle's farm. He pay's her $0.30 per container for the first 50
containers of strawberries that she picks in a day and $0.50 per container for all containers picked
over 50. On Friday Susie picked 175 containers of strawberries. How much did she earn?
Answers
Answer:
77.5
Step-by-step explanation:
For 0.30 for the first 50, just subtract 50 from 175, that leaves 125.
(An easy way to do this is think of quarters, 25+25=50 and 50+25=75 so all you have to do is subtract two 25s and you know it's 125)
Put the 125 to the side, and multiply 50 to 0.30, you get 15.
Then for 0.50 over 50 containers, multiply the remaining 125 with 0.50, you get 62.5.
Add 62.5 and 15 together, that gives you 77.5

[tex]s = l \times w = 1.8 \times 1.2 = 2.16[/tex]
s=2.16 m²
