What is AE?
Enter your answer in the box.
Answer:
x = 4
Step-by-step explanation:
AE = ED
2x+4 = x+8
Subtract x from each side
2x+4-x = x+8-x
x+4 = 8
Subtract 4 from each side
x+4-4 = 8-4

A few students finished up their NCVPS work early and are playing skip
rope. As the rope rotates it is observed that its maximum height is 2.75m
after 1 second. The first minimum height of 0.25m occurs 2 seconds after
the maximum height. Sketch a graph to model the situation.
Answer:
see attached
Step-by-step explanation:
The graph can be shown as a sine wave with a maximum of 2.75 m and a minimum of 0.25 m. Its period will be twice the time from maximum to minimum, so will be 2×2 seconds = 4 seconds. The midline of the graphed function will be halfway between the extremes, at 1.5 m.
The equation of the graph will put the first peak at 1 second, so if a cosine function is used, it will have a horizontal shift of 1 second to the right.

Answer:
Its x-intercepts are at (0,0) and (11,0)
The x-coordinate of its vertex is 5.5
Step-by-step explanation:
(both of the answers)
Step-by-step explanation:
x intercept is where you graph cuts the x axis
put this equation equal to 0 and then solve for x
[tex]2x(x - 11) = 0 \\ 2x = 0 \: \: \: \: \: or \: \: \: \: \: x - 11 = 0 \\ x = 0 \: \: \: or \: \: \: \: x = 11[/tex]
so x intercept is (0,0) and (11,0).
To find vertex
x coordinate is -b/2a
[tex]2x(x - 11) \\ 2x {}^{2} - 22x \\ so \: vetex \: is \: - \frac{ - 22}{2(2)} \\ \frac{22}{4} \\ 5.5[/tex]

All triangles in this shape have same area as they have same base length and height length.
area of triangle: 1/2 * base * heightHere the base is 4.2 cm and height is 2.5 cm for all the given triangles.
As a result, we can say that the area of [tex]\triangle[/tex] A, [tex]\triangle[/tex] B, [tex]\triangle[/tex] C are equal.
Answer:
area A = 5.25 cm²
area B = 5.25 cm²
area C = 5.25 cm²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
area of A = 1/2 x 4.2 x 2.5 = 5.25 cm²
area of B = 1/2 x 4.2 x 2.5 = 5.25 cm²
area of C = 1/2 x 4.2 x 2.5 = 5.25 cm²
Triangles A, B and C have the same area as they all have the same measures of base and height.

Esther cycles 70 miles over 4 days.
On day 1 she cycles 14 miles.
On day 2 she cycles 32 km.
On day 4 she cycles twice as far as she does on day 3
How far does she cycle on day 4?
Give units with your answer.
Answer:
16
Step-by-step explanation:
70 - 14 - 32 = 24 (Which is the amount of miles she cycled on both Day 3 and 4)
x + x*2 = 24
8 + 8*2 = 24
8 + 16 = 24
Therefore, she cycles 24 miles on Day 4.

A store is having a sale in which all bookbags are discounted by `30\%`. Mai has a coupon for `\$5` off the regular price of one bookbag. The store first applies this coupon, and then takes `30\%` off the reduced price. Mai pays `\$23.10` for the bookbag.
You said the equation represents this scenario, and the solution to your equation was `\$35.56`.
Explain what the solution to the equation means within the context of the problem.
The regular price of the book bag was $38.
EquationAn equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the regular price of the bag. After applying the coupon:
Price = x - 5
After the discount:
23.10 = (x - 5) - 30% of (x - 5)
23.10 = (x - 5) - (0.3x - 1.5)
0.7x - 3.5 = 23.10
x = 38
The regular price of the book bag was $38.

A taxi ride costs $3 plus $2.50 per mile. Write and graph an equation that represents the total cost of a taxi ride. Let m represent number of miles and c represent the total cost (in dollars) of the taxi ride. What is the total cost of a five-mile taxi ride?
Answer:
The answer is 3 + 2.50m = c.
Step-by-step explanation:
You would use the slope equation: y = mx+b where y is equal to the total cost of a taxi ride, in dollars and m is equal to the number of miles. $3 is your base cost which represents your y-intercept or your b and $2.50 represents your slope.

Arielle is filling up the kiddie pool for her younger sister and places a hose in the pool, allowing water to fill the pool. After a certain number of minutes, Arielle finds a second hose, places it in the kiddie pool, and allows more water to fill the pool.
Arielle can express the average rate of water entering the kiddie pool in gallons per minute as 2x+6(x+3)/2x+3.
What is the meaning of the parts of this rational expression in the context of the situation?
Select from the drop-down menus to correctly complete the statements.
The numerator of the rational expression represents the ____
The denominator of the rational expression represents the ____
Possible solutions for the fill in the blank above:
A. Total number of gallons of water in the kiddie pool.
B. Total number of minutes filling the kiddie pool.
C. Number of gallons each hose dispenses.
The given rational function that gives the average rate of water entering
the pool is the total volume in the pool divided by the time.
Response:
The numerator of the rational expression represents the;
A. Total number of gallons of water in the kiddie pool
The denominator of the rational expression represents the;
B. Total number of minutes of filling the kiddie pool
Which methods are used to determine the parts of the rational function?The given parameters are;
[tex]Expression \ for \ average \rate \ of \ water \ entering \ the \ pool = \mathbf{ \dfrac{2 \cdot x + 6 \cdot (x + 3)}{2 \cdot x + 3}}[/tex]
The parts of the given expression can be analyzed as follows;
x = The time in which the second hose is in use
2 = The flow rate of the second hose in gallons per minute
6 = The flow rate of the first hose in gallons per minute
x + 3 = The time in which the first hose is in use
x + x + 3 = 2·x + 3 = The total number of minutes of filling the kiddie pool
Therefore;
2·x = The volume added to the pool due to the second hose
6·(x + 3) = The volume added to the pool due to the first hose
2·x + 6·(x + 3) = Total number of gallons of water in the kiddie pool
Which gives;
The numerator of the rational expression represents the;
A. Total number of gallons of water in the kiddie pool
The denominator of the rational expression represents the;
B. Total number of minutes of filling the kiddie pool

(PLS HELP)The diameter of a cylindrical water tank is 12 ft, and its height is 14 ft. What is the volume of the tank?
Use the value 3.14 for л, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Solution:
First, let's find the radius with the given diameter.
⇒ Diameter = 2(Radius)
⇒ 12 ft = 2(Radius)
⇒ 6 ft = Radius
The area of the cylinder is basically the area of a circle in the cylinder multiplied by the height of the cylinder. This means that the volume of the cylinder is πr²h. Now, let's find the volume of the cylinder.
⇒ πr²h = Volume of cylinder
⇒ (3.14)(6²)(14) = Volume of cylinder
⇒ (3.14)(36)(14) = Volume of cylinder
⇒ 1582.56 ft³ = Volume of cylinder

Answer:
[tex]\sf\: Area \: of \: the \: triangle \: = \boxed{\boxed{\bf\:50 \: cm^{2}}}[/tex]
Step-by-step explanation:
Given,
The triangle is an isosceles triangle.
Base (b) = 10 cmHypotenuse = 13 cmAltitude (h) = Base = 10 cm [isosceles triangle has equal opposite sides]Since, we are given the hypotenuse, the triangle will be an isosceles right angled triangle.
We know that, area of a right angled triangle = ½ × b × h
By substituting the values in the above formula...
½ × b × h
= ½ × 10 × 10
= ½ × 100

What is f(5) if f(1) = 3. 2 and f(x 1) = Five-halves(f(x))?
Function assign value from one set to another. The value of f(5), if f(1) = 3.2 and f(x+1) = Five-halves(f(x)) is 125.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
As it is given the value of the function f(1) is 3.2, while the value of f(x+1) is [tex]f(x+1) = \dfrac{5}{2}[f(x)][/tex], therefore, in order to find the value of f(5), we need to calculate the value of f(4).
f(2)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(2)=f(1+1) = \dfrac{5}{2}[f(1)]\\\\f(2) = 2.5 \times 3.2\\\\f(2) = 8[/tex]
f(3)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(3)=f(2+1) = \dfrac{5}{2}[f(2)]\\\\f(3) = 2.5 \times 8\\\\f(3) = 20[/tex]
f(4)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(4)=f(3+1) = \dfrac{5}{2}[f(3)]\\\\f(4) = 2.5 \times 20\\\\f(4) = 50[/tex]
f(5)
[tex]f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(5)=f(4+1) = \dfrac{5}{2}[f(4)]\\\\f(5) = 2.5 \times 50\\\\f(5) = 125[/tex]
Hence, the value of f(5), if f(1) = 3. 2 and f(x+1) = Five-halves(f(x)) is 125.
