Answer:
17 cm
Step-by-step explanation:
If the angle between V and W is 90°, then this implies that V and W are legs of a right triangle (and the distance between them is the hypotenuse).
Use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle.
Let D = distance between V and W:
⇒ V² + W² = D²
⇒ 8² + 15² = D²
⇒ 289 = D²
⇒ D = √289
⇒ D = 17
Therefore, the distance from V to W is 17 cm
[tex]\huge \boxed{\sf 17\ cm}[/tex]
Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides.
[tex]\sf a^2 + b^2=c^2\\\\8^2 + 15^2=c^2\\\\ \sqrt{8^2 + 15^2} =c\\\\17=c[/tex]

Question 1:
I'm sorry, for this question I am not 100% sure that this answer is correct, but I am going to go with "standard form." I chose this answer because standard form tends to be one of the most easiest methods to use when it comes to graphing, besides the slope intercept form of "y=mx+b." Standard form is also one of the most useful forms to use when finding intercepts, which in this case the question is mentioning the x-intercept.
Question 2:
So for this question, it is asking you about translations on graphs. When a line is translated units away from another line, it means that it is typically the same line just moved an amount of units over.
(I have included the graphs in the attachment. The red line represents the first equation given, and the blue line represents the second equation that was translated up.)
The graph shows that the second (blue) line was translated 3 units up.
I hope that this helps.

Answer:
1824 in²
Step-by-step explanation:
This figure consists of a triangle and a rectangle.
To find the area of the entire figure , we have to find the area of the triangle and the rectangle separately and add them.
Let us solve now.
Area of the triangle
Area = [tex]\frac{1}{2}[/tex] × base × height
Area = [tex]\frac{1}{2}[/tex] × 48 × 12
Area = [tex]\frac{1}{2}[/tex] × 576
Area = 288 in²
Area of the rectangle
Area = length × width
Area = 48 × 32
Area = 1536 in²
Area of the entire figure
Total area = Area of the triangle + Area of the rectangle
Total area = 288 in² + 1536 in²
Total area = 1824 in²

Explanation:
The number [tex]7 \times 10^{10}[/tex] is the number 7 followed by 10 zeros
[tex]7 \times 10^{10} =[/tex] 70,000,000,000 = 70 billion
According to statista.com, there are roughly 229 million drivers in the US (based on a 2019 survey).
Divide the two amounts to get:
(70 billion)/(229 million) = (70*1000 million)/(229 million) = 305.677 approximately
This indicates that each driver uses about 306 gallons of gas per day.
This value is way too high.
Therefore, the initial claim does not make sense.
------------
Upon further research, the site eia.gov states that Americans use about 337 million gallons of gasoline per day (not 70 billion).
Notice how (337 million)/(229 million) = 1.472 approximately which is far more realistic. It makes more sense to have any given driver use somewhere between 1 or 2 gallons of gas per day. Of course, all of this depends on the person's location from home to work, the amount of traffic, etc.

Sally lives 18 miles from Job A. A work week is five days. How many miles would she have to drive each week just to get to and from work?
Answer:
Sally would have to drive 180 mi in a workweek.
Step-by-step explanation:
You multiply the number of miles it takes her to get to her job by how many times she drives to and from work a day. (She drives 18 mi to work and 18 to get home) (18•2=36) So she drives 36 mi in one day. Then you multiply the number of miles she drives per day (36) by how many days she works a week (5) and you get 180 mi in a workweek.

how maNY solutions do these equations have? No solution, one solution, infinite solutions.
a) y = 2x + 3 and y = -2x + 11
b) y = x + 2 and -2x + 2y = 4
c) y = x - 3 and y = x + 6
d) y = 7 and y =3x-5
e) y = -4x and y = -4x - 1
Answer:
See below.
Step-by-step explanation:
a) y = 2x + 3 and y = -2x + 11
One solution. They are straight lines with different slopes, so they will intersect at some point.
b) y = x + 2 and -2x + 2y = 4
-2x + 2y = 4 can be rearranged to 2y = 2x +4 and then y = x + 4
Both lines have the same slope, 1. They are parallel and will never meet. No solutions.
c) y = x - 3 and y = x + 6
This has the same answer as c. Parallel lines (both have slopes of 1.). They will never meet: no solutions.
d) y = 7 and y =3x-5
One solution. Straight lines with different slopes (3 and 0) so they will cross at one point. [At (4,7)]
e) y = -4x and y = -4x - 1
Same slopes. There are no solutions.

What are the factors and zeros of the function f(x)=−2x2+7x+15?
Solving the quadratic function, it is found that the factors/zeros of the function are given by x = -1.5 and x = 5.
What are the factors/zeros of a function?They are given by the solutions of the function, that is, the values of x for which f(x) = 0.
In this problem, the function is given by:
f(x) = -2x² + 7x + 15.
Then:
-2x² + 7x + 15 = 0.
Which is a quadratic function with coefficients a = -2, b = 7, c = 15, hence:
[tex]\Delta = 7^2 - 4(-2)(15) = 169[/tex]

Pamela's age is three times Jiri's age. The sum of their ages is 116. What is Jiri's age?
Answer:
29
Step-by-step explanation:
Let Jiri's age be 'x'. Pamela's age is 3x since Pamela's age is three times Jiri's age.
The sum of their ages is 116:
x + 3x = 116
4x = 116
x = 116 ÷ 4 = 29
x = 29
Jiri's age is 29

A student increases the temperature of a 100 cm³ balloon from 60°C to 120°C. What will the new volume of the balloon be? 118 cm³ 200 cm³ 236 cm³ 400 cm³.
Volume is directly proportional to the temperature. The volume of the new balloon is given by: Option B: 200 cm³
What is the relation between volume and temperature for a gas?If the initial volume and temperatures for a gas(assuming behaving ideally) are written as: [tex]V_1[/tex] and [tex]T_1[/tex], and the changed volume and temperatures are [tex]V_2[/tex] and [tex]T_2[/tex], then we have:
[tex]\dfrac{V_1}{T_1} = \dfrac{V_2}{T_2}[/tex]
For the given case, we are provided that:
Volume of balloon at [tex]T_1 = 60^\circ C[/tex] is [tex]V_1 = 100 \: \rm cm^3[/tex]
Let for temperature [tex]T_2 = 120^\circ C[/tex], we get volume of balloon (which is the volume of the air inside it) as [tex]V_1 = x \: \rm cm^3[/tex]
Then, by the volume-temperature ratio, we get:
[tex]\dfrac{V_1}{T_1} = \dfrac{V_2}{T_2}\\\\\dfrac{100}{60} = \dfrac{x}{120} \implies x = 2 \times 100 = 200 \: \rm cm^3[/tex]
Thus, the volume of the new balloon is given by: Option B: 200 cm³

A restaurant owner washed 94 kilograms of vegetables, some spinach and some cucumbers. The spinach came in 10-kilogram bags and the cucumbers came in 9-kilogram bags. The owner washed 10 bags of vegetables in all. How many bags of each kind did he wash?
Answer:
6 bags of cucumber
4 bags of spinach
Step-by-step explanation:
let s = number of bags of spinach
let c = number of bags of cucumber
If the owner washed 10 bags of vegetables in total, then
s + c = 10
The spinach came in 10kg bags and the cucumbers came in 9kg bags, and the owner washing 94kg of veg in total:
10s + 9c = 94
Rewrite s + c = 10 to make s the subject, substitute it into 10s + 9c = 94, then solve for c:
s + c = 10
⇒ s = 10 - c
⇒ 10(10 - c) + 9c = 94
⇒ 100 - 10c + 9c = 94
⇒ -c = -6
⇒ c = 6
Substitute c=6 into s + c = 10 and solve for s:
s + 6 = 10
⇒ s = 4
In a blueprint, each square has a side length of 1/4 inch. Ceramic tile costs $5 per square foot. How much would it cost to tile the bathroom? Carpet costs $18 per square yard. How much would it cost to carpet the bedroom and living room?
(as you can see, I already got the answer for a. I just need the answer for b.)
b.
Bedroom area
Lenght = 5 squares
= 5 × 1/4 inchi
= 5/4 inchi
Width = 4 squares
= 4 × 1/4 inchi
= 1 inchi
Large area = 5/4 × 1 inchi
= 5/4 inchi
Living room
Lenght = 7 squares
= 7 × 1/4 inchi
= 7/4 inchi
Width = 4 squares
= 4 × 1/4 inchi
= 1 inchi
Large area = 7/4 × 1 inchi
= 7/4 inchi
Total Area
Bedroom area + Living room area
= 5/4 + 7/4
= (5+7)/4 inchi
= 12/4 inchi
= 3 inchi
1 square yard = 1296 square inches
so 1 square inches = 1/1296 square yard
3 inchi = 3×1/1296
= 3/1296
= 1/432
Cost = 1/432 × $18
= $1/24
It would cost $1/24 to carpet the bedroom and living room.
