Given u=(5,-2,3) and v=(1,1,2) find ordered triple that represents 3u-2v

kipiarov [429]

Answer:

(13, -8, 5)

Step-by-step explanation:

Given

$u = (5,-2,3)\\and\\v = (1,1,2)$

We have to find 3u-2v

So,

$3u = 3(5,-2,3)\\3u= (15,-6,9)\\\\And\\\\2v= 2(1,1,2)\\2v= (2,2,4)\\\\3u-2v = (15,-6,9) - (2,2,4)\\= (15-2, -6-2 , 9-4)\\= (13, -8, 5)$

The ordered triple that represents 3u-2v is:

(13, -8, 5) ..

A pair of sunglasses has 2 lenses. Each lenses has a radius of 3.5 inches.

sineoko [7]

Answer:

76.93

Step-by-step explanation:

bc your formula is A=πrsquared so 3.14(π) ×3.5×3.5 bc when it's squared it's the number times itself93

so 3.14×3.5×3.5=38.456

38.456+38.456 because you need the area for both so I added the same number to it or you can multiply by 2 if you want

38.456+38.456=76.93

1The volumes of two similar prisms are 972 cm3 and 36 cm3. The surface area of the larger prism is 594 cm2.

diamong [38]

Answer:

Part 1)

The scale factor of the smaller prism to the larger prism is 3

The scale factor of the larger prism to the smaller prism is 1/3

Part 2) The surface area of the smaller prism is 66 square centimeters

Step-by-step explanation:

Part 1) What is the scale factor for the similar figures?

we know that

If two figures are similar, then the ratio of their volumes is equal to the scale factor raised to the cube

Let

z ----> the scale factor

x ---> volume of the larger prism

y ---> volume of the smaller prism

$z^3=\frac{x}{y}$

we have

$x=972\ cm^3\\y=36\ cm^3$

substitute

$z^3=\frac{972}{36}$

Simplify

$z^3=27\\z=3$

therefore

The scale factor of the smaller prism to the larger prism is 3

The scale factor of the larger prism to the smaller prism is 1/3

Part 2) What is the surface area of the smaller prism?

we know that

If two figures are similar, then the ratio of their surface areas is equal to the scale factor squared

Let

z ----> the scale factor

x ---> surface area of the larger prism

y ---> surface area of the smaller prism

$z^2=\frac{x}{y}$

we have

$x=594\ cm^2$

$z=3$

substitute

$3^2=\frac{594}{y}$

solve for y

$y=\frac{594}{9}=66\ cm^2$

therefore

The surface area of the smaller prism is 66 square centimeters
