Answer:

A translation 2 units downward and reflection about the y-axis.

Step-by-step explanation:

The sequence of transformations that is applied to the quadrilateral ABCD to map onto the quadrilateral A"BC"D" is:

A translation 2 units downwards and then a reflection of the quadrilateral about y-axis.

( Since on translating two units downward all the coordinates of the vertex of the quadrilateral will be shifted two units down i.e. there will be a change in y-values and no change in x-values of the coordinates; and hence on reflecting about the y-axis, the image A"B"C"D" will be obtained )

Answer:

C. 0.75 in

Step-by-step explanation:

Given

d = 5 in
V = 176.715 in³

Find the height of cylinder:

V = πr²h
π(5/2)²h = 176.715
h = 176.715/(6.25π)
h = 9 in

Two parallelogram-shaped pieces of tile have the same area. One has a base of 20 centimeters and a height of 15 centimeters. The

gtnhenbr [62]

Answer:

height = 12 cm

Step-by-step explanation:

Parallelogram 1:

Area = base *height = 20 * 15 = 300 sq. cm

Area of parallelogram 2 = area of parallelogram 1

25 * height = 300

height = 300/25

height = 12 cm

Solve the equation!3 tan^3θ = tan θ

andreev551 [17]

3 tan³ t(theta) = tan t(theta)
3 tan³ t - tan t = 0
tan t ( 3 tan² t - 1 ) = 0
tan t = 0
t 1 = k π , k ∈ Z
3 tan ² t - 1 = 0
3 tan ² t = 1
tan ² t = 1/3
tan t = +/- √3/3
t 2 = π / 6 + k π
t 3 = - π / 6 + k π , k ∈ Z

Part A: You have $0.80 in your backpack in dimes and quarters. Let x represent the number of dimes and y represent the number of

Alik [6]

Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3
Therefore you have 3 dimes
