Using it's concept, the range of the given exponential function is:

C. 0 < y ≤ 46638.

The range of a function is the set that contains all possible output values for the function.

In this problem, the function is:

y = 46,638(0.78)^x.

It is an exponential function with initial value 46,638 and rate of change 0.78. Exponential functions that are not shifted down, such as this one, are never negative nor zero, hence the range also has the restriction y > 0, and is given by:

C. 0 < y ≤ 46638.

Answer:

B

Step-by-step explanation:

Image B displays a segment perpendicular to AC.

Constructions are precise drawings of geometric shapes, angles, and lines. We'll need a pencil, a ruler (a straight-edge), and compasses to do this. The fundamental constructions are the perpendicular bisector and the angle bisector.

Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.

If two geometric objects intersect at a right angle, they are perpendicular. The perpendicular symbol can be used to represent the condition of perpendicularity graphically. It can be defined between two lines, a line and a plane, or two planes.

In image B, the bisector BD is dividing the line AD into two equal halves.

The total cost is represented as C = $0.50x + $4300  and the average cost as avgC = $0.50 + $4300/x

We have been given that,

The variable cost for producing the game = $0.50 per unit

The fixed cost for producing the game = $4300

Let the total cost be denoted by C.

And let x be the number of games produced.

a) Total cost = variable cost + fixed cost

          C = $0.50x + $4300

b) Average cost = total cost/number of games produced

                        = C/x

                        = ($0.50x + $4300)/x

                        = $0.50 + $4300/x

Hence the total cost is C = $0.50x + $4300 and the average cost is $0.50 + $4300/x

= 144 - 3 [ 4([tex]\frac{1}{4}[/tex] - 1) ]

The average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h

The function is given as

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

The interval is given as

[1, 1 + h]

Calculate f(1) as follows

So, we have

f(1) = 1/(1 + 5)

f(1) = 1/6

Calculate f(1 + h) as follows

So, we have

f(1 + h) = 1/(1 + h + 5)

f(1 + h) = 1/(h + 6)

The average rate of change of f(x) on the interval [1,1+h] is then calculated as

Rate = [f(1 + h) - f(1)]/[1 + h - 1]

This gives

Rate = [1/(h + 6) - 1/6]/h

Hence, the average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h

Answer:

I don't know it like off

Step-by-step explanation:

so, the best way to help you is to help you understand how to solve such problems yourself.

let me know if you still don't understand something :

4.

this you can solve just by common sense.

let's see if you understand it with smaller numbers :

1 ball costs $3. how much will 2 balls cost ? well, twice as much : 2×3 = $6.

how much will 3 balls cost ? hmmm ? three times as much : 3×3 = $9.

and so on.

so, how much will 10 balls cost ? right, ten times a much : 10×3 = $30.

now,

8 eggs for 3 cups of flour.

how many eggs for 30 cups of flour ? you notice that 30 is 10 times 3, right ?

yes, ten times a many eggs : 10×8 = 80 eggs.

5.

3 quarters simply means 3/4.

if we want to know how much 3/4 of something is, we have to multiply that something by 3/4.

so, for 60 students :

60 × 3/4 = 180/4 = 45 students bring a lunch from home.

6.

similar to 4.

5 books in 2 days.

how many books in 8 days ?

you notice that 8 is 4 times 2 ?

so, yes, 4 times as many books : 4×5 = 20 books.

7.

now we are getting into areas, where we need more thinking and apply formal mathematics.

10 pounds jam requires 5 pounds apples.

8 pounds jam require x pounds apples.

the easiest way is to use ratios :

jam to apples = 10/5 = 2/1 = 2

8 pounds jam to x pounds apples must follow the same ratio, as we are using the same recipe.

8/x = 2

8 = 2x

x = 4

so, to get 8 pounds of jam we need 4 pounds of apples.

8.

it seems they were very, very hungry ...

Jenny ate 6 1/4 pizzas.

Dolly ate 5 1/4 pizzas.

6 1/4 = (6×4 + 1)/4 = 25/4

5 1/4 = (5×4 + 1)/4 = 21/4

so, Jenny ate 25/4 / 21/4 = 25/21 = 1.19047619... times more pizza.

or in other words she ate

25/4 - 21/4 = 4/4 = 1 more pizza.

9.

so, he wins 5 of every 15, that is a ratio of 5/15 = 1/3.

he had 75 matches. 1/3 of 75 matches (see also 5.) means

75 × 1/3 = 75/3 = 25.

he won 25 matches.

The value of x in the equation is x = -8/30

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The equation is given as

3x + 8 = 7.2

Subtract 8 from both sides of the equation

3x = -0.8

Divide both sides by 3

x = -0.8/3

Rewrite as

x = -8/30

-21 - -8 = -13

Because of the two subtract signs next to each other before the number 8, they change to an addition sign.

From -21, move right 8 places along the number line because it is add 8.
