Find f(4) for f(x) = 4x + 3. f(4) =

Mathematics
1 answer:
adell [148]3 years ago
3 0

Answer:

f(4) = 19

Step-by-step explanation:

Since we are given f(4), we substitute the x values with the number 4.

f(x) = 4x + 3

f(4) = 4(4) + 3

After substituting the x values with 4, solve the equation normally.

f(4) = 16 + 3

f(4) = 19

Our final answer is f(4) = 19

A ball is thrown into the air with a velocity of 34 ft/s. It's height in feet after t seconds is given by y=34t-26(t)^2. Find th
kkurt [141]

Answer:

The average velocity of the ball at the given time interval is -122.3 ft/s

Step-by-step explanation:

Given;

velocity of the ball, v = 34 ft/s

height of the ball, y = 34t - 26t²

initial time, t₀ = 3 seconds

final time, t = 3 + 0.01 = 3.01 seconds

At t = 3 s

y(3) = 34(3) - 26(3)² = -132

The average velocity of the ball in ft/s is given as;

V_{avg} = \frac{y(3.01)-y(3)}{3.01 -3}\\\\V_{avg} = \frac{34(3.01)-26(3.01)^2-y(3)}{3.01 -3}\\\\V_{avg} = \frac{-133.223-y(3)}{0.01}\\\\V_{avg} = \frac{-133.223-(-132)}{0.01}\\\\V_{avg} =\frac{-1.223}{0.01}\\\\V_{avg} = -122.3 \ ft/s

Therefore, the average velocity of the ball at the given time interval is -122.3 ft/s

Anne-marienhas saved 9 dollars for a new coat that is 1/6 as much money as she needs how much does the coat cost
Tatiana [17]

Answer:

Cost of the coat = $54

Step-by-step explanation:

Given:

She saved = $ 9

To Find:

Cost of the coat = ?

Solution:

Let the price of coat be x

She saved $9

and according to given condition it is 1/6 of the total money she needs for buying coat

by this we have

\frac{1}{6}*x = 9

Multiplying both sides by 6

\frac{1}{6}*x*6 = 9*6

it becomes

x = 9*6

x = $54

As x is the amount she needs

so

Cost of the coat = $54

what is the area of the shaded sector of the circle if the radius is 14 ft? leave your answer in terms of pi
Strike441 [17]

Given:

Radius = 14 ft

θ = 45°

To find:

Area of the shaded sector

Solution:

Area of the sector formula:

$\text { area of sector }=\frac{\theta}{360^{\circ}} \times \pi r^{2}

                      $=\frac{45^\circ}{360^{\circ}} \times \pi \times 14^{2}

                      $=\frac{1}{8} \times \pi \times 196

                      =24.5\pi ft²

The area of the shaded sector of a circle is 24.5π ft².
