Dilate line f by a scale factor of 2 with the center of dilation at the origin to create line f. Where are points A' and B' loca
V125BC [204]

Answer:

Option A

Step-by-step explanation:

We are given that

Scale factor=2

Center of dilation=(0,0)

Point A(0,2) and point B (2,0).

Slope of line f=\frac{y_2-y_1}{x_2-x_1}

Substitute the values

Slope of line f=\frac{0-2}{2-0}=-1

Distance between  A and Origin (0,0) is given by

OA=\sqrt{(0-0)^2+(0-2)^2}=2 units

Using distance formula

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

OB=\sqrt{(0-2)^2+(0-0)^2}=2 units

Length of OA'=2OA=2(2)=4 units

Length of OB'=2(OB)=2(2)=4 units

x-intercept of line f' at x=4

y-intercept of line f' at y=4

Therefore, the points A' and B' are given by

(0,4) and (4,0)

Slope of line f'=\frac{0-4}{4-0}=-1

Slope of line f and f' are equal.Therefore, lines f and f' are parallel.

Option A is true.

Chee is flying a kite, holding her hands a distance of 3.25 feet above the ground and
Mademuasel [1]

The height of the kite above the ground is 58.68 ft

Let x be the height of the kite above Chee's hand.

The height of the kite above Chee's hand, the string and the horizontal distance between Chee and the kite form a right angled triangle with hypotenuse side, the length of the string and opposite side the height of the kite above Chee's hand.

Since we have the angle of elevation from her hand to the kite is 29°, and the length of the string is 100 ft.

From trigonometric ratios, we have

tan29° = x/100

So, x = 100tan29°

x = 100 × 0.5543

x = 55.43 ft.

Since Chee's hand is y = 3.25 ft above the ground, the height of the kite above the ground, L = x + y

= 55.43 ft + 3.25 ft

= 58.68 ft to the nearest hundredth of a foot

So, the height of the kite above the ground is 58.68 ft
