Answer:

f(x) = -5x - 4

Step-by-step explanation:

We want to get the inverse of the following function:

f^-1(x) = (-1/5)x - 4/5

To do that, we have to replace x with f(x) and f^-1(x) with x, as follows:

x = (-1/5)f(x) - 4/5

And then solve for f(x), the inverse of f^-1(x).

x + 4/5 = (-1/5)f(x)

f(x) = -5x + (-5)4/5

f(x) = -5x - 4

To check our result we compute a pair (x, f(x))

x   f(x)

1   -5*1 - 4 = -9

which has to be equivalent to (-9, 1) in the original function

x      f^-1(x)

-9     (-1/5)*(-9) - 4/5 = 1

PIT_PIT [208]

Answer:

0.43478

Step-by-step explanation:

From the information given:

The \  required  \ probability = P(1st ball = red) \times P(2nd ball = red) + P(1st ball = red) \times P(2nd ball = white)  + P(2nd ball = red) \times P(1st ball = white) + P(1st ball = white) \times P(2nd ball = white)

= \dfrac{6}{6+8+10}\times  \dfrac{5}{5+8+10} +  \dfrac{6}{6+8+10} \times  \dfrac{10}{5+8+10} +  \dfrac{10}{6+8+10} \times  \dfrac{6}{5+8+10} \times  \dfrac{10}{6+8+10} \times  \dfrac{9}{5+8+9}

=(\dfrac{6}{24}\times \dfrac{5}{23})+ (\dfrac{6}{24}\times \dfrac{10}{23}) +( \dfrac{10}{24}\times \dfrac{6}{23} ) + (\dfrac{10}{24}\times \dfrac{9}{23})

= 0.05434782609 + 0.1086956522  + 0.1086956522  + 0.1630434783

= 0.4347826088

≅ 0.43478

I need help answering this question.
Usimov [2.4K]

Answer:

28 degrees

Step-by-step explanation:

Since the lines are parallel this means that angle BEF and angle ABE are equal because they are alternate interior angles. We are given a right angle which measures 90°. This means we can do 118°-90° to give us angle ABD. This means that angle ABD is 28°.
