Which choice shows the coordinates of C' if the trapezoid is reflected across the y-axis? On a coordinate plane, trapezoid A B C D has points (2, 1), (3, 5), (5, 3) and (3, 1).
Answer:
[tex]C'\ = (-5,3)[/tex]
Step-by-step explanation:
Given
[tex]A = (2, 1)[/tex]
[tex]B = (3, 5)[/tex]
[tex]C = (5, 3)[/tex]
[tex]D = (3, 1).[/tex]
Reflection across y-axis
Required
Coordinates of C'
When a point is reflected across the y-axis, the rule is:
[tex](x,y) \to (-x,y)[/tex]
So, the reflection on C will be:
[tex]C\ (5,3) \to C'\ (-5,3)[/tex]
Answer:
A
Step-by-step explanation:
(-5,3)

On a scale drawing, the height of a tree is 3.75 inches. If the scale of the drawing is 1 in. : 50 ft, how tall is the tree?
HINT: Write and solve a proportion. You will compare 1 in to 50 feet and then determine how many feet 3.75 inches would be. REMEMBER: When writing your proportion, be sure that whichever (inches or feet) is on top and bottom of one ratio, it is in the same position (top or bottom) on other ratio.
A
187.5 ft
B
13.3 in.
C
187.5 in.
D
13.3 ft
Answer:
187.5 ft
Step-by-step explanation:
50 ft x 3.75 = 187.5
An air traffic controller at an airport sights a plane at an angle of elevation of 28º.
The pilot reports that the plane's altitude is 4500 feet.
To the nearest foot, what is the distance from the control tower to the plane?
3190 ft
8463 ft
2113 ft
9585 ft
Answer:
8463 feets
Step-by-step explanation:
Using the diagram attached :
Distance of control tower to plane = d
Using tro:
Tan θ = opposite / Adjacent
Tan 28 = 4500 / d
0.5317094 = 4500 / d
0.5317094d = 4500
d = 4500 / 0.5317094
d = 8463.2690

Is the ordered pair (-2, 1) a solution to the equation - 3x + y = 5?
No
Yes
Answer:
No
Step-by-step explanation:
Plug (-2,1) into -3x+y=5. This will make it -3(-2)+(1)=5. This is equal to 6+1=5. 7=5. 7 is not equal to 5. Therefore, (-2,1) is not a solution to the equation -3x+y=5.

What is the measure of the inscribed angle that shares endpoints with a central angle measuring 58 degrees?
Answer:
29 degrees
Step-by-step explanation:
See attached image of an inscribed angle together with a central angle.
An inscribed angle is half the measure of the central angle! Always! In my image, if the measure of angle CAB is 58 degrees, then that is also the measure of arc CB. The inscribed angle CDB is half the measure of the intercepted arc CB, so it's 29 degrees.

Answers:
A) The equation is d = 2tB) Independent variable = time; dependent variable = amount of cookies=========================================================
Explanation:
The independent variable is always long the horizontal axis. Often this is x, but we are using t in this case.
The variable t represents the amount of time in minutes. For instance, t = 2 means 2 minutes have elapsed. At this time, 4 cookies have been eaten as shown by the point (2,4). As another example, the point (3,6) means that d = 6 cookies have been eaten at time t = 3 minutes.
The equation is d = 2t because the '2' represents the rate of change of "eating 2 cookies per minute". Whatever the time value (t) is, we double it to get the value of d, which is the number of cookies eaten.

PLS HELP ASAP RIGHT NOWWW
Answer:
The correct answer is 1/3.
Step-by-step explanation:
The reason why is because there is 3 animals. Then one beaver. So it would be 1/3.
Answer:
0.33
Step-by-step explanation:
Because they are all equal, each animal has to have the same percentage. Because there are 3 options it can land on, the denominator is 3. Because the beaver is 1 of the 3, the answer is 1/3. 1/3 is equal to 0.33 rounded so the answer is 0.33.
Solve for X:
2.5x+12=32
Step-by-step explanation:
2.5x+12=32
We move all terms to the left:
2.5x+12-(32)=0
We add all the numbers together, and all the variables
2.5x-20=0
We move all terms containing x to the left, all other terms to the right
2.5x=20
x=20/2.5
x=8
The value of x for the expression is,
⇒ x = 8
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Expression is,
⇒ 2.5x + 12 = 32
Now, We can solve for x as;
⇒ 2.5x + 12 = 32
Subtract 12 both side,
⇒ 2.5x + 12 - 12 = 32 - 12
⇒ 2.5x = 20
Divide by 2.5 both side,
⇒ x = 20 / 2.5
⇒ x = 200 / 25
⇒ x = 8
Thus, The value of x for the expression is,
⇒ x = 8

I need this answered quick alot of points on the line here 2 pictures down below
Answer:
1.x=10 and x=−2.
2. the answer is x=7,-1
3.=3, =1
Step-by-step explanation:
1.Since it is a quadratic equation, then it has, at the most, two solutions because the square root of the variable has a positive and negative value. Thus, the solutions to the given equation are x=10 and x=−2.
2.Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. the you would simplify the equation.and the last thing that is to separate the equation.

Choose the algebraic description that maps the image ΔXYZ onto ΔX′Y′Z′. Question options: A)
(x, y) → (x + 6, y – 1)
B)
(x, y) → (x – 5, y – 1)
C)
(x, y) → (x + 5, y – 1)
D)
(x, y) → (x – 6, y – 1)
Answer:
D
Step-by-step explanation:
To get from ΔXYZ (the figure on the right) to ΔX′Y′Z′ (the figure on the left), each point is translated left 6 units and down 1.
Movement left and right is related to the x-axis. So moving 6 units left (in a negative direction) is x - 6.
Movement up and down is related to the y-axis. So going down (in the negative direction) is y - 1.
