Answer:

${f}^{ - 1} (x) = 9x + 18$

Step-by-step explanation:

$f(x) = \frac{1}{9}x - 2$

$y = \frac{1}{9} x - 2$

$x = \frac{1}{9}y - 2$

$x + 2 = \frac{1}{9}y$

$9x + 18 = y$

${f}^{ - 1} (x) = 9x + 18$

Answer:

212.5

Step-by-step explanation:

Here's a theorem about triangle areas.

If two similar triangles have sides in the ratio x:y,

then their areas are in the ratio x2:y2

The triangles have sides in the ratio:

LP/LN = 10/25

The two triangles have areas in the ratio 100:625 (4/25)

For every 4 in the small triangle, there are 25 in the larger triangle.

34/4 = 8.5

25 times 8.5 =212.5

A slow pitch softball diamond is actually a square 60 ft on a side. how far is it from home to second base?

krek1111 [17]

For this case we have a square whose sides are known and equal to 60 ft.
We want to find the diagonal of the square.
For this, we use the Pythagorean theorem.
We have then:
$d^2 = 60^2 + 60^2

d = \sqrt{60^2 + 60^2}

 d = \sqrt{3600 + 3600}

d = \sqrt{2*3600}

d = 60\sqrt{2}
$
Answer:
from home to second base it is about:
$d = 60\sqrt{2} feet$

Y = 3x - 1 ---- (1)
x - y = -9 ---- (2)

From Equation 2:
x - y = - 9
x + 9 = y
y = x + 9 --- (2a)

(1) - (2a):
0 = 3x - x - 1 - 9
0 = 2x - 10
2x - 10 = 0
2x = 10
x = 5 ---- sub into (1)

y = 3(5) - 1
y = 15 - 1
y = 14
