Answer:
With respect to angle A, a is opposite, b is adjacent, c is the hypotenuse
With respect to angle B, b is opposite, a adjacent, and c is the hypotenuse.
Step-by-step explaination:
To find the opposite side of an angle of a right triangle - look at the side that is directly across from that angle. For example, angle A shows that the side directly across from it is side a.
To find the adjacent side of an angle of a right triangle - look at the side that is right next to it and connected to the 90 degree angle. For example, angle B shows that the side that is next to it and connected to the 90 degree angle is side b.
The hypotenuse will always be the longest side opposite the 90 degree angle.
Reflect (7,3) across the y-axis.
Then reflect the result across the y-axis again.
What are the coordinates of the final point?
Answer:
(7, 3)
Step-by-step explanation:
If we reflect a point/figure across the y-axis, the rule is (x, y) -> (-x, y).
(7, 3) -> (-7, 3)Now, let's reflect it against the y-axis again.
(-7, 3) -> (7, 3)As you can see, we're back to where we started- at (7, 3). Thus, we can conclude that reflecting across the y-axis twice will result in the original point/figure.

The bumper car ride at the state fair has 2 red cars, 3 green cars, and 3 blue cars. Janet is first in line for the ride and is assigned a car at random. Sarah is next in line and is randomly assigned a car. What is the probability that both Janet and Sarah will drive a red bumper car? Express your answer as a percent. If necessary, round your answer to the nearest tenth.
96.4%
25%
6.3%
3.6%
The probability (in percentage form) is 3.6%, so the correct option is the last one.
How to find the probability?First, Janet is assigned to a car. We want to find the probability that it is a red car. All the cars have the same probability of being assigned, then the probability of getting a red car is equal to the quotient between the number of red cars and the total number of cars:
p = 2/(8) = 1/4
Now there is 1 red car left and 7 cars in total left.
Sarah is next on line, the probability that she gets a red car will be:
q = 1/7
The joint probability (the probability of both of these events happening) is given by the product of the two individual probabilities, so we get:
P = (1/4)*(1/7) = 0.036
If we multiply this by 100%, we get:
P = 100%*0.036 = 3.6%
So the correct option is the last one.

The number 4 siblings are least likely to be selected
What is the number of a sibling to be selected?Probability is the likelihood of an event occurring or not. Probability value ranges from impossibility(0) to certainty(1).
The lower the value, the less likely the event is bound to occur.
From the probability distribution table, the probability of having 4 siblings at the game is 0.
This is the lowest out of all the given values in the probability distribution table. Therefore, it is the least likely event.
Thus the number 4 siblings are least likely to be selected

Step-by-step explanation: Thomas is very beautiful and he come to my house to visite it.
Anita needs to build a house for a school project. The base of the house is a rectangle where the length of a rectangle is 8 more than the width. Its area is 240 ft sq
L = lengh
W = width
french reasoning ( hello from France ) !
The base of the house is a rectangle where the length of a rectangle is 8 more than the width.
=> L = W + 8
and
Its area is 240 ft sq
W x L = 240
L = W + 8
W x L = 240
=> W x (W+8) = 240
W² + 8W - 240 = 0
Δ = 8² - 4*1*(-240) = 32²
W' = (-8 + 32) / 2 = 12 ft
W'' = (-8 - 32) / 2 = impossible
at the end
W the width = 12 ft
and then the lengh = 12 + 8 = 20
area = 12 x 20 = 240 ft²

Answer: h(t)=[tex]16x^{2} \\\\[/tex]+80t+4
Step-by-step explanation:
80 if feet per second so it's 80*seconds where seconds equals t

Round your answer to 1 decimal place.
Help!!!
Answer:
Step-by-step explanation:
Note:
Circumference of a circle = [tex]\pi d[/tex]
Where d = diameter
We are given the diameter is 20cm, d = 20
Circumference of circle = [tex]\pi d[/tex] = 20 [tex]\pi[/tex]
Also, perimeter of a rectangle = 2 times length + 2 times width
We are told the length = 18 , width = x
Perimeter of rectangle = 2 times 18 + 2 times x
Perimeter of rectangle = 36 + 2x
The question also tells us that the circumference of the circle is EQUAL to the perimeter of the rectangle:
So this means:
Since Circumference of circle = 20[tex]\pi[/tex] ,
Perimeter of rectangle = 36 + 2x .
We can write:
Circumference of circle = perimeter of rectangle
20[tex]\pi[/tex] = 36 + 2x
Subtract 36 from both sides
20[tex]\pi[/tex] - 36 = 2x
Divide both sides by 2 to solve for "x".
x = [tex]\frac{20\pi - 36 }{2} = ?[/tex]

The revenue function for a bicycle shop is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x)=800−0.5x is the unit price. Find the maximum revenue.
Answer:
The maximum revenue is $320,000
Step-by-step explanation:
To find the maximum of a function f, the procedure is as follows:
Find the first derivative of f.Equate the derivative to 0. Solve the resulting equation to get the critical points.Try all the critical points in the original function and select the one that maximizes it.The revenue function for a bicycle shop is
R(x)=xp(x), where p(x)=800-0.5x. Substituting:
[tex]R(x)=x(800-0.5x)=800x-0.5x^2[/tex]
Find the first derivative of R:
R'(x)=800-x
Equate to 0:
800-x=0
Solve:
x=800
There is only one critical point. Substitute it into the revenue function:
[tex]R(800)=800(800)-0.5(800)^2=320,000[/tex]
The maximum revenue is $320,000

What is the volume of a sphere with a radius of 2.5 units?
Answer: A sphere (from Greek σφαῖρα—sphaira, "globe, ball") is a geometrical object that is a three-dimensional analog to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.
Step-by-step explanation: The formula used to calculate the sphere radius is: r = ∛((3/4) · V / π) Symbols. r = Sphere radius; V = Sphere volume; π = Pi = 3.14159… The volume of Sphere. Enter the volume contained within a sphere. The radius of Sphere. This is the radius of a sphere that corresponds to the specified volume.
