lesya692 [45]

Answer:

There are two statements that are true:

B. QR = 5.9 cm

D. Measure of angle R = 47 degrees

Step-by-step explanation:

1. Let's recall that if ΔVWX ≅ ΔPQR, then:

VW ≅ PQ

WX ≅ QR

PR ≅ VX

therefore, QR is 5.9 cm and not 4.5 cm

2. Let's recall that if ΔVWX ≅ ΔPQR, then:

∠V ≅ ∠P

∠W ≅ ∠Q

∠X ≅ ∠R

therefore, measure of ∠R is 47° and not 28°

There are two statements that are true:

B. QR = 5.9 cm

D. Measure of angle R = 47 degrees

A circle has a radius of 9 inches. The Radius is multiplied by 2/3 to form a second circle. How is the ratio of the areas relate

liraira [26]

Answer:

$\frac {(Area\ of\ first\ circle) }{(Area\ of\ second\ circle)} = \frac{81}{36} = (\frac{r_{1} }{r_{2}}) ^{2}$

The above expression shows that ratios of the areas of the circles are equal to the square of the ratio of their radii.

Step-by-step explanation:

Radius of first circle $(r_{1})$ = 9 inches

Area of first circle = $\pi r_{1} ^{2}$

Area of first circle = 9 × 9 × π = 81 π

Now, since the radius is multiplied by 2/3 for from a new circle.

∴ Radius of the second circle = $9 \times \frac{2}{3} = 6\ inches$

Area of second circle = $\pi r_{2} ^{2}$

Area of second circle = 6 × 6 × π = 36 π

Now,

$\frac {(Area\ of\ first\ circle) }{(Area\ of\ second\ circle)} = \frac{81\pi }{36\pi }$

$\frac {(Area\ of\ first\ circle) }{(Area\ of\ second\ circle)} = \frac{81}{36} = (\frac{9}{6}) ^{2} = (\frac{r_{1} }{r_{2}}) ^{2}$

∵ $(r_{1})$ = 9 inches and $(r_{2})$ = 6 inches

The above expression shows that ratios of the areas of the circles are equal to the square of the ratio of their radii. i.e., $\frac {radius\ of\ first\ circle)^{2} }{(radius\ of\ second\ circle)^{2} } = \frac {(Area\ of\ first\ circle) }{(Area\ of\ second\ circle)}$

Suppose you graphed every single point of the form $(2t + 3, 3-3t)$. For example, when $t=2$, we have $2t + 3 = 7$ and $3-3t = -

netineya [11]

Answer:

see below for explanation

3x +2y = 15

Step-by-step explanation:

The x-coordinate and the y-coordinate are both linear functions of t, so their relationship to each other is linear. A graph of those (x, y) points must be a line.

___

You can find an equation by solving one of the expressions for t, then substituting that into the other.

x = 2t +3

t = (x -3)/2

Substituting into the y expression, we get ...

y = 3 -3(x -3)/2

y = (-3/2)x + 15/2

3x +2y = 15 . . . . . . . add 3/2x and multiply by 2 to put into standard form

_____

The attached graph shows a portion of the line defined parametrically (0 ≤ t ≤ 1). It is dotted so you can see it overlays the line defined by the linear equation in x and y.
