Step-by-step explanation:

Answer: f(g(-11)) = out  -23

Step-by-step explanation:

The value of the composite function (fog)(-11) is 3√14 - 41.

When the output of one function is given to the input of another function they are called composite functions.

In (fog)x which is [f{g(x)}] here the out of the function g(x) is the input of the function f(x).

Given, Are two functions f(c) = 3c - 8 and g(c) = √14 - c.

Now, We know that (fog)(c) is the output of g(c) is in the input of f(c).

So, g(-11) = √14 - 11.

Therefore,

(fog)(-11) = 3(√14 - 11) - 8.

(fog)(-11) = 3√14 - 33 - 8.

(fog)(-11)  = 3√14 - 41.

Answer:

x =20°

Step-by-step explanation:

since both sides are equal

3x° = (5x-40°)

3x = 5x - 40°

CLT( collect like terms)

40°= 5x - 3x

40° = 2x

40°/2= 2x/2

20° = x

therefore x =20°

Using linear equations, A rental car company charges prices based on the number of days you rent the car will charge  $185 if you rent the car for 7 days.

A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Let us consider the number of days = x

The equation when number of days(x) <= 4,

⇒ $50 + $25x1 = y1

If the car is rented for more than 4 days, (x>4)

⇒ $45 + $20x2 = y2

Now, we are to calculate the rent for 7 days,

which equals,

y2 = $45 + $20x2

for x2 = 7,

y2 = $45 + $20 × 7

⇒ 45 + 140

⇒ $185

A)- The distribution is skewed left.

B)- The histogram has one​ mode, at 74 to 76 years.

The distribution of numerical data is roughly shown by a histogram. Karl Pearson is credited with coining the phrase. The first stage in creating a histogram is to "bin" (or "bucket") the range of values, or split it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as a series of discrete intervals that don't overlap. Histograms provide a general idea of the density of the underlying distribution of the data, and are frequently used for density estimation: estimating the probability density function of the underlying variable. The bins (intervals) must be adjacent and are frequently (but not always) of equal size.

The number of wins is 68 ad losses is 26.

Let the number of losses = l

Therefore, the number of wins will be: = (2 × l) + 16 = 2l + 16

Total games = 94

Therefore we will add the equation

l + 16 + 2l = 94

3l + 16 = 94

3l = 94 - 16

3l = 78

Divide

l = 78/3

l = 26

Losses = 26

The change in temperature is 33°F.

According to the question we have been given that there are two temperature readings which are, -18°F and 15°F.

We need to find the change in temperature that is we need to find the difference. And for that we will use distance formula.

The formula to find the distance between the two numbers p and q is

                                    = |p-q|

Here , p = -18°F  and q = 15°F

Putting the required values in the above formula we get

                     = |-18 - 15| °F

                     = |-33| °F

                     = 33°F

We need to add the total volume of liquid that the patient consumes.

First, we need to rewrite both volumes in mL, remember that:

1 pint = 568.26 mL

Then for the 1/2-pint of apple juice:

1/2 pint = (1/2)*568.26 mL = 284.13 mL

And:

1L = 1000L

For the liter we have:

The new depth of the orange juice is now 4cm

From the question, we are to calculate the depth of the orange juice after Jane turns the carton

First, we will determine the volume of orange juice in the carton.

The volume of orange juice in the carton = 10 cm × 6 cm × 8cm

Volume of orange juice in the carton = 480 cm³

Now, we will determine the depth of the orange juice when the carton stands on the shaded face

If carton stands on the shaded face,

The length becomes 20 cm

and

The width becomes 6 cm

Let the new depth of the orange juice be h

Then,

We can write that

480 = 20 × 6 × h

480 = 120 × h

h = 480/120

h = 4 cm
