The point (3,22) lies on the graph of f(x) = 3ˣ - 5. The medication in an adult male reduces by half per hour can represent an exponential function.

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Given the function:

f(x) = 3ˣ - 5

At point (3, 22):

f(3) = 3³ - 5 = 22

The point (3,22) lies on the graph of f(x) = 3ˣ - 5.

The medication in an adult male reduces by half per hour can represent an exponential function.

Answer:

The other endpoint is (-33, 17)

Step-by-step explanation:

The rule of the mid-point of a segment whose endpoints are

([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) is

In our question

∵ The coordinates of the endpoints of a segment are (-15, 13) and (x, y)

∴ [tex]x_{1}[/tex] = -15 and [tex]x_{2}[/tex] = x

∴ [tex]y_{1}[/tex] = 13 and [tex]y_{2}[/tex] = y

∵ The coordinates of the mid-point of this segment are (-24, 15)

∴ [tex]x_{M}[/tex] = -24 and [tex]y_{M}[/tex] = 15

→ Use the rule of the mid-point to find x and y

∵ [tex]-24=\frac{-15+x}{2}[/tex]

→ Multiply both sides by 2

∴ -48 = -15 + x

→ Add 15 to both sides

∴ -33 = x

∵ [tex]15=\frac{13+y}{2}[/tex]

→ Multiply both sides by 2

∴ 30 = 13 + y

→ Subtract 13 from both sides

∴ 17 = y

∴ The other endpoint is (-33, 17)

If two triangles are similar, that means their side lengths are proportional, so we get the equation

 [tex]\frac{AB}{AC} =\frac{FG}{FH} \\\frac{x}{17} =\frac{16}{20} \\20x = 16 * 17\\x=13.6[/tex]

Thus x = 13.6.

Answer:

Below.

Step-by-step explanation:

a) Let the numbers be n, n + 2 and n + 4

Sum = n + n + 2 + n + 4

= 3n + 6.

As n must be even (2, 4, 6 and so on) , 3n must be divisible by 6  and 3n + 6 is divisible by 6 also.

b) 3n + 6 = 6000

3n =  5994

n = 5994/3 = 1998

So the numbers are 1998, 2000 and 2002.

2. writing the equation this way shows how much money raised per child ticker

Step-by-step explanation:

Answer:

Ok, so we know that you can't simply divide a decimal as it is (if you're using long division)

For example, let's take  the quotient of 2.2 and -22

22÷ -2.2

so to get it into a whole number, multiply each value by 10 to get rid of decimal point

220 ÷ -22

when you divide, you are left with negative ten. Remember when you divide a negative and a positive number together, the result will always be negative

The extra amount that Tim is expected to pay is approximately given by: Option D:  $57.88

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, the question is missing the fact that the size of the tank is 11.75 gallon and a gallon of gas costs $4.50.

So, the total cost of 11.75 gallon of gas is:

Cost of 11.75 gallon gas = 11.75 * 4.50 = 52.875 (in dollars)

Also from the question, the cost of refueling a vehicle is $5.00.

So, the total cost for refueling the car of Tim is:

Total cost = cost of gas + cost of refueling the car

Total cost  = 52.875 + 5.00

Total cost  = $57.875 ≈ $57.88

Thus, the extra amount that Tim is expected to pay is approximately  given by: Option D; $57.88

Step-by-step explanation:1 third of 9 is 3. Half of 10 is 5. Multiply 5 by 3. It is now 15.

Answer:

15

Step-by-step explanation:

Work backwards:

half of 10 = 10 ÷ 2 = 5

so ... nine times half of 10 = 9 × 5 = 45

so  ... ⅓ of nine times half of ten = ⅓ of 45 = 45 ÷ 3 = 15

Step-by-step explanation:

8x - 4 + 1.5x + 15

8x + 1.5x = 9.5x

-4 + 15 = 11

9.5x + 11

Expression = 9.5x + 11

Without Simplifying = 19/2x + 11

Answer:

9.5x + 11

Step-by-step explanation:

First, distribute the 4 to (2x - 1) to get 8x - 4. Distribute 3 to (1/2x + 5) to get 3/2x + 15. Put them back together to get 8x - 4 + 3/2x + 15. Combine like terms to get 9.5x + 11.

Answer:

  (25 -5√7)/3 ≈ 3.924 inches

Step-by-step explanation:

After removing squares from the corners and folding up the sides, the open-top box will have dimensions ...

  x × (20 -2x) × (30 -2x)

The maximum value for this cubic expression in the domain 0 < x < 10 is found easily by a graphing calculator to be at x = 3.924 inches.

__

You can solve this by expanding the cubic and finding the solution that makes its derivative equal to 0.

  V(x) = 4x^3 -100x^2 +600x

The derivative is ...

  V'(x) = 12x^2 -200x +600 = 0

Dividing by 12, we have ...

  x^2 -50/3x +50 = 0

Completing the square, we get the form ...

  (x -25/3)^2 = -50 +(25/3)^2 = (-450 +625)/9 = 175/9

Taking the square root gives ...

  x -25/3 = ±(5√7)/3

The solution in the desired range is ...

  x = (25 -5√7)/3 ≈ 3.924 . . . inches

We limit the value of x to half the width of the cardboard material, as any longer cuts would overlap to create a negative box dimension. The graph shows the maximum volume to be about 1056.3 cubic inches. Box dimensions would be 3.924 in deep by 12.153 in by 22.153 in.

Answer: 34 degrees

Step-by-step explanation:

Since the sum of the measure of x and 56 = 90 because a right angle is 90 degrees, we can solve for x.

x + 56 = 90

x = 34

Answer:

34º

Step-by-step explanation:

the box in the graph means a 90º angle. if 56 and x make up 90º, its a simple subtraction problem. 90º-56º=34º.

Answer:

(i) 0.15708

(ii) 0.432488

(iii) 3

Step-by-step explanation:

Given that, 99% of people who fracture or dislocate a bone see a doctor for that condition.

There is only two chance either the person having fracture or dislocation of bone will either see the doctor or not.

As per previous data, if one person got a fracture or dislocation of bone, the chance of seeing the doctor is 0.99. Assuming this chance is the same for every individual, so the total number of people having fractured or dislocated a bone can be considered as Bernoulli's population.

Let p be the probability of success represented by the chances of not seeing a doctor by any one individual having fractured or dislocated a bone.

So, p=1-0.99=0.01

According to Bernoulli's theorem, the probability of exactly r success among the total of n randomly selected from Bernoulli's population is

[tex]P(r)=\binom{n}{r}p^r(1-p)^{n-r}\cdots(i)[/tex]

(i) The total number of persons randomly selected, n=400.

The probability that exactly 5 of them did not see a doctor

So, r=5 , p=0.01

Using equation (i),

[tex]P(r=5)=\binom{400}{5}(0.01)^5(1-0.01)^{400-5}[/tex]

[tex]=\frac{400!}{(400-5)!\times 5!}(0.01)^5(0.99)^{395}[/tex]

=0.15708

(ii) The probability that fewer than four of them did not see a doctor

[tex]=P(r<4)[/tex]

[tex]=P(r=0)+P(r=1)+P(r=2)+P(r=3)[/tex]

[tex]=\binom{400}{0}(0.01)^0(0.99)^{400}+\binom{400}{1}(0.01)^1(0.99)^{399}+\binom{400}{2}(0.01)^2(0.99)^{398}+\binom{400}{3}(0.01)^3(0.99)^{397}[/tex]

[tex]=0.017951+0.072527+0.146154+0.195856[/tex]
