Answer:

A translation of 3 units to the right and a translation of one unit upwards.

Step-by-step explanation:

When we analyze translations of whole figures, all the points in the figure suffer the same translation, then we only need to analyze the translation of one of the points.

This means that we can only see the translation from A to A'

First, let's find the coordinates of each point:

A (2, 3)

A' (5, 4)

The translation is given if we calculate the difference between these coordinates:

A' - A =  (5, 4) - (2, 3) = (5 - 2, 4 - 3) = (3, 1)

The change in the x-value is 3.

The change in the y-value is 1.

Then we can conclude that:

A' is 3 units at the right of A

A' is 1 unit above A.

Then the translation is:

A translation of 3 units to the right and a translation of one unit upwards.

If A is the area of a circle with radius r and the circle expands as time passes, find dA/dt in terms of dx/dt
valina [46]
The area of a circle in terms of the circle's radius r is

A=\pi r^2

Differentiating both sides with respect to t, you get

\dfrac{\mathrm dA}{\mathrm dt}=2\pi r\dfrac{\mathrm dr}{\mathrm dt}

The number of people who attended a concert on Friday was 3/4 the number of people who attended the same concert on Saturday. A
LiRa [457]

On Saturday, 4/4 of the amount of people attended.  On Friday, 3/4 of the amount on Saturday attended.  We have 7 parts (3 from Friday and 4 from Saturday).

840/7 = 120.

Thus, 360 people attend on Friday and 480 on Saturday.

Question-

To build a door frame, Anthony needs 2 pieces of lumber that each measure 98 1/4 inches and one piece of lumber that measure 39 1/2 inches. What is the total length of lumber that Anthony needs to build the frame?

Answer:

137 3/4 inches

Step-by-step explanation:

98 1/4 + 39 1/2

First, find the LCD (4)

98 1/4 + 39 2/4

98 + 39 = 137

1/4 + 2/4 = 3/4

Quadrilateral ABCD is inscribed in this circle. What is the measure of angle c?
alexandr402 [8]
3x+x+20 = 180
4x = 180-20
4x = 160
x = 40

×+20+3x+2x+38+C=360
40+20+3×40+2×40+38+C=360
40+20+120+80+38+C=360
298+C=360
C=360-298
C =62°
