A builder makes drainpipes that drop 1 cm over a

LUCKY_DIMON [66]

Answer:

700.4 cm

Step-by-step explanation:

This involves two similar triangles.

Both triangles are right triangles.

One has legs measuring 1 cm and 30 cm. We can find the hypotenuse by using the Pythagorean theorem.

(1 cm)^2 + (30 cm)^2 = c^2

c^2 = 901 cm^2

c = sqrt(901) cm

The second triangle has one leg with length 700 cm. This leg corresponds to the 30-cm leg in the other triangle. Since the triangles are similar, we can use a proportion to find the hypotenuse of the second triangle.

(30 cm)/(700 cm) = [sqrt(901) cm]/x

3/70 = sqrt(901) cm/x

3x = 70 * sqrt(901) cm

x = 70 * sqrt(901) cm/3

x = 700.4 cm

Answer: 700.4 cm

Option C

<u>SOLUTION:</u>

We need to find the value of B - CF

First find the value CF:

$CF=\left[\begin{array}{ccc}12&0&1.5\\1&-6&7\\\end{array}\right] \left[\begin{array}{ccc}-2&0\\0&8\\2&1\end{array}\right]$

$CF=\left[\begin{array}{ccc}12(-2)+0 *0+1.5*2&12*0+0.8+1.5*1\\1*(-2)+(-6)*0+7.2&1*0+(-6)*8+7.1\\\end{array}\right]$

$CF=\left[\begin{array}{ccc}-21&1.5\\12&-41\\\end{array}\right]$

Now find value of B - CF:

$B-CF=\left[\begin{array}{ccc}2&8\\6&3\\\end{array}\right] -\left[\begin{array}{ccc}-21&1.5\\12&-41\\\end{array}\right]$

$B-CF=\left[\begin{array}{ccc}23&6.5\\-6&44\\\end{array}\right]$

∴ the value of B - CF is $\left[\begin{array}{ccc}23&6.5\\-6&44\\\end{array}\right]$

A rhombus TEMPhas coordinates A(-6, 3)

olga_2 [115]

Answer:

A'(-6, -8)
B'(-7, -6)
C'(-6, -4)
D'(-5, -6)

Step-by-step explanation:

A 90° CCW rotation makes the transformation ...

(x, y) ⇒ (-y, x)

A translation 3 left and 2 down makes the transformation ...

(x, y) ⇒ (x -3, y-2)

The two transformations together are ...

(x, y) ⇒ (-y-3, x -2)

Then the given points are transformed to ...

A'(-6, -8)

B'(-7, -6)

C'(-6, -4)

D'(-5, -6)
