What Are The Vertices Of AA'B'C'if AABC Is Dilated By A Scale Factor Of 2?A(0, 10)108(8,6)C(4,2)46810O

Answers

Answer 1

Answer:

Option B

Step-by-step explanation:

Rule for the dilation of point (x, y) by a scale factor 'k' about the origin,

(x, y) → (kx, ky)

By this rule vertices of triangle ABC when dilated by a scale factor of 2 to form ΔA'B'C',

A(0, 10) → A'(0, 20)

B(8, 6) → B'(16, 12)

C(4. 2) → C'(8, 4)

Therefore, Option B will be the correct option.

determine the measure of angles A and B

Answers

Answer:

Angle A is 52 degrees           Angle B is 78 degrees

Step-by-step explanation:

The angles all have to add up to 180.

2x + 3x + 50 = 180

5x + 50 = 180

Subtract 50 from both sides

5x = 130

Divide each side by 5

x = 26

Solve

A) 2 * 26 = 52

B) 3 * 26 = 78

--------Check--------

52 + 78 +50 = 180

180 = 180

There are values of tso that sin t= .6 and cost=.8
A. True
B. False

Answers

The correct answer to the given postulate as required in the task content is; Choice A; True.

Which is correct about the given postulate?

It follows from the task content that it is required to verify if there are values of t such that; sin t= .6 and cost=.8.

Recall from square trigonometric identities that;

sin² x + cos² x = 1.

To verify if sin t= .6 and cost=.8 satisfy the given condition;

sin² t + cos² t = 1;

i.e (.6)² + (.8)² = 1

.36 + .64 = 1.

1 = 1; True.

Ultimately, the statement that t can take values such that sin t= .6 and cost=.8 is True.

A garden is shaped like a rectangle whose perimeter is 150 ft. The length is 2 times as long as the width. Find the length and the width.

Answers

Answer:

Step-by-step explanation:

L=2W

P=2(L+W), using L=2W this becomes

P=2(2W+W)

P=2(3W)

P=6W, given P=150

6W=150

W=25, and since L=2W

L=50 so

L=50ft and W=25ft

3 Ramón makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 cups of water with 3 cups of sugar. Whose nectar is more sugary? Explain.​

Answers

Answer:

Tiffany's nectar is more sugary

Step-by-step explanation:

Given

Ramon:

[tex]Water = 8\ cups[/tex]

[tex]Sugar = 2\ cups[/tex]

Tiffany

[tex]Water = 9\ cups[/tex]

[tex]Sugar = 3\ cups[/tex]

Required

The nectar with more sugar

To do this, we simply calculate the fraction of sugar in both nectar.

This is calculated as:

[tex]Fraction = \frac{Sugar}{Sugar + Water}[/tex]

For Ramon:

[tex]Fraction = \frac{2}{8 + 2}[/tex]

[tex]Fraction = \frac{2}{10} = 0.20[/tex]

For Tiffany

[tex]Fraction = \frac{3}{3 + 9}[/tex]

[tex]Fraction = \frac{3}{12} = 0.25[/tex]

From the calculations above:

[tex]0.25 > 0.20[/tex]

Hence: Tiffany's nectar is more sugary

Step-by-step explanation:

From the figure,

13x - 55 = 88 (Opposite angles made by two straight lines are equal)

13x = 88 + 55

13x = 143

x = 143/13

x = 11

Again,

88 + z = 180 (Sum of angles of a straight line)

z = 180 - 88

[tex]c=x^2+y^2[/tex]

To find:

The Pythagorean triple generated by using 4 for x and 1 for y.

Solution:

Substituting x=4 and and y=1 in the given equations, we get

[tex]a=4^2-1^2[/tex]

[tex]a=16-1[/tex]

[tex]a=15[/tex]

In the same way find b and c.

Measure of arc BC isdegrees​

Answers

Answer:

A. 98

Step-by-step explanation:

Based on inscribed angle theorem, the inscribed angle (<D) is half of the angle subtended by the arc BC. That is:

m<D = ½(BC)

m<D is given as 49°

Thus,

49° = ½(BC)

Multiply both sides by 2

2(49) = BC

98° = BC

BC = 98°

what is the frequency of a wave that had a wavelength of 15m and is traveling at 135 m/s English questionsOne-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the Southern part of it. These slaves constituted a peculiar and powerful interest. All knew that this interest was, somehow, the cause of the war. To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union, even by war; while the government claimed no right to do more than to restrict the territorial enlargement of it. Neither party expected for the war, the magnitude, or the duration, which it has already attained. Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease. Each looked for an easier triumph, and a result less fundamental and astounding. Both read the same Bible, and pray to the same God; and each invokes His aid against the other. It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces; but let us judge not that we be not judged. The prayers of both could not be answered; that of neither has been answered fully. The Almighty has His own purposes. "Woe unto the world because of offenses! for it must needs be that offenses come; but woe to that man by whom the offense cometh! If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South, this terrible war, as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a Living God always ascribe to Him? Fondly do we hope. fervently do we pray that this mighty scourge of war may speedily pass away. Yet, if God wills that it continue, until all the wealth piled by the bondman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash, shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether." With malice toward none; with charity for all; with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in; to bind up the nation's wounds; to care for him who shall have borne the battle, and for his widow, and his orphan-to do all which may achieve and cherish a just, and a lasting peace, among ourselves, and with all nations. 1.
