A moose population is growing exponentially following the pattern in the table shown below. Assuming that the pattern continues, what will be the population of moose after 12 years?
years=x population =y
0,40
1,62
2,96
3,149
4,231
The population of the moose after 12 years is 7692
Step-by-step explanation:
The form of the exponential growth function is [tex]y=a(b)^{x}[/tex] , where
a is the initial valueb is the growth factorThe table:
→ x : y
→ 0 : 40
→ 1 : 62
→ 2 : 96
→ 3 : 149
→ 4 : 231
To find the value of a , b in the equation use the data in the table
∵ At x = 0 , y = 40
- Substitute them in the form of the equation above
∵ [tex]40=a(b)^{0}[/tex]
- Remember any number to the power of zero is 1 (except 0)
∴ 40 = a(1)
∴ a = 40
- Substitute the value of a in the equation
∴ [tex]y=40(b)^{x}[/tex]
∵ At x = 1 , y = 62
- Substitute them in the form of the equation above
∵ [tex]62=40(b)^{1}[/tex]
∴ 62 = 40 b
- Divide both sides by 40
∴ 1.55 ≅ b
∴ The growth factor is about 1.55
- Substitute its value in the equation
∴ The equation of the population is [tex]y=40(1.55)^{x}[/tex]
To find the population of moose after 12 years substitute x by 12 in the equation
∵ [tex]y=40(1.55)^{12}[/tex]
∴ y ≅ 7692
The population of the moose after 12 years is 7692

In the next 10 months Colin wants to save $900 for his vacation. He plans to save $75 each for the first eight months. How much must he save each of the last two months in order to meet his goal if he saves the same amount each month
He must save $150 each of the last two months in order to meet his goal.
Step-by-step explanation:
Given,
Amount Colin wants to save = $900
Amount saved each month for 8 months = $75
Amount saved in 8 months = 75*8 = $600
Let,
x be the amount saved each month for remaining two months.
Therefore;
Number of months * Amount saved + Amount saved in 8 months = Total amount to save
[tex]2x+600=900\\2x=900-600\\2x=300[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{300}{2}\\x=150[/tex]
He must save $150 each of the last two months in order to meet his goal.

Determine the diameter of a curcle with the radius 12.2
Answer:
24.4
Step-by-step explanation:
diameter=2*radius
=2*12.2
=24.4
Final answer:
The diameter of a circle with a radius of 12.2 is 24.4 units. This is calculated by doubling the radius, using the formula D = 2r.
Explanation:
To determine the diameter of a circle with a radius of 12.2, you simply need to use the relationship between the radius and the diameter of a circle. The diameter is twice the radius, which can be represented by the formula D = 2r, where D is the diameter and r is the radius.
Substituting the value of the radius into the formula gives us:
D = 2 × 12.2
This calculates to:
D = 24.4
Therefore, the diameter of the circle is 24.4 units. Keep in mind that if the radius was given in a specific unit, like meters or centimeters, then the diameter will be in the same unit.
f(x) = -x^3+ 6x – 7 at x = 2
Answer:
f(2)= -4
Step-by-step explanation:
f(x)= -x^3 + 6x - 7
f(2) = -2^3 + 6*2 - 7
f(2)= -8 +12 -7
f(2)= 3-7
f(2)= -4
The value of the function f(x)=-x^3+6x-7 at x=2 is -3.
Explanation:To find the value of the function f(x) = -x^3 + 6x - 7 at x = 2, we substitute the value of x into the function.
So, f(2) = -(2)^3 + 6*(2) - 7 = -8 + 12 - 7 = -3.
Thus, the value of the function at x = 2 is -3. This is a simple algebraic operation involving cubes and multiplication, which are basic arithmetic operations.

A line has a slope of -3/4 and has a y intercept of 3. What is the x intercept of the line
Answer:
The x-intercept is 4
Step-by-step explanation:
We are given;
The slope of a line as -3/4
y-intercept is 3
We are supposed to determine the x-intercept;
We need to know that;
The slope of a line is given by the ratio of the change in y to the change in x
The coordinates of y-intercept are (0, 3)
Taking the x-intercept as a, then the coordinates of x-intercept is (a, 0)
But;
slope = Δ in y ÷ Δ in x
Therefore;
[tex]\frac{0-3}{a-0}= \frac{-3}{4}[/tex]
Solving for a
[tex]-3a = -12 \\ a =4[/tex]
Therefore, the x-intercept is 4

Sarah wants to place a rim around her circular pool with a foam rim. The foam rim is
sold in boxes that will cover the length of 40 feet. How many boxes of foam rim will
Sarah need to place around the rim of the pool?
4 boxes
(A) 3 boxes
(B) 4 boxes
(C) 5 boxes
(D) 6 boxes
Answer:
3 boxes.
Step-by-step explanation:
The circular pool has a radius of 16 feet.
So, the circumference of the pool will be 2πr = [tex]2 \times \frac{22}{7} \times 16 = 100..57[/tex] feet.
Therefore, to place a rim around the circular pool with a foam rim Sarah will need 100.57 feet length of foam rim.
Now, the foam rim is sold in boxes that will cover the length of 40 feet.
Therefore, she will need [tex]\frac{100.57}{40} = 2.51[/tex] ≈ 3 boxes to place around the rim of the pool. (Answer)
Which function has a range of y < 3?
y=3(2)*
y=2(3)
y=-(2)*+ 3
O y=(2]*_3
Answer:
The function given by [tex]y = - (2)^{x} + 3[/tex] will have a range of y < 3.
Step-by-step explanation:
The function given by [tex]y = - (2)^{x} + 3[/tex] will have a range of y < 3.
This is because, for any real values of x, the term [tex]- (2)^{x}[/tex] will have a negative value. If we put x = 1, then, [tex]- (2)^{x}[/tex] = - 2, and for x = -1, then [tex]- (2)^{x}[/tex] = - 0.5.
That means [tex]- (2)^{x} < 0[/tex] for all real x.
Hence, [tex]- (2)^{x} + 3[/tex] < 0 + 3
⇒ y < 3 for all real x. (Answer)
What is a equal to?
12=2a
Using the balance method, we find a = 15 by isolating the variable a. Substituting a = 15 back into the original equation, we verify the solution.
To solve the equation 12 = 2a - 18 using the balance method, we aim to isolate the variable a on one side of the equation.
Starting with 12 = 2a - 18, we'll first add 18 to both sides to isolate the term with 2a:
[tex]\[12 + 18 = 2a - 18 + 18\]\[30 = 2a\]\\[/tex]
Next, we divide both sides by 2 to solve for a:
[tex]\[\frac{30}{2} = \frac{2a}{2}\]\[15 = a\][/tex]
Now, let's verify the solution by substituting a = 15 back into the original equation:
[tex]\[12 = 2(15) - 18\]\[12 = 30 - 18\]\[12 = 12\][/tex]
Since the left side equals the right side, the solution a = 15 is verified.
Complete Question:
Solve the following equation using balance method and verify 12 = 2a - 18
A party rental company has chairs and tables for rent. The total cost to rent 3 chairs and 2 tables is $22. The total cost to rent 5 chairs and 6 tables is $60. What is the cost to rent each chair and each table?
Answer:
The cost to rent each chair and each table are $1.5 and $8.75 respectively
Step-by-step explanation:
Let x represent 1 chair
Let y represent 1 table
Therefore
3x + 2y = 22 ------------(1)
5x + 6y = 60 ------------(2)
Multiply (1) by 5 and (2) by 3
15x + 10y = 110 ----------(3)
15x + 18y = 180 ------------(4)
Subtract (3) from (4)
8y = 70
Divide through by 8
y = $8.75
Substitute y = 8.75 in (1)
3x + 2y = 22
3x + 2(8.75) = 22
3x + 17.5 = 22
Collect like terms
3x = 22 - 17.5
3x = 4.5
Divide through by 3
x =$1.5
Final answer:
By setting up a system of linear equations based on the given information and solving it, we determined that the cost to rent each chair is $1.50 and the cost to rent each table is $8.75.
Explanation:
To find the cost to rent each chair and each table from the party rental company, we set up a system of linear equations based on the information given:
3 chairs and 2 tables cost $22.5 chairs and 6 tables cost $60.Let C be the cost of one chair and T be the cost of one table. We can write the following equations:
3C + 2T = $225C + 6T = $60Solving this system of equations, we can find the values of C and T. First, multiply the first equation by 3 to eliminate T:
(3C + 2T) * 3 = 22 * 39C + 6T = $66Now we can subtract the second equation from the modified first equation:
9C + 6T - (5C + 6T) = $66 - $604C = $6C = $1.50With the cost of a chair known, we can substitute back into either equation to find the cost of a table:
3(1.50) + 2T = $224.50 + 2T = $222T = $22 - 4.502T = $17.50T = $8.75The cost to rent each chair is $1.50 and the cost to rent each table is $8.75.

You are trying to order 1/4 pound of saffron, but the ordering system wants a decimal.What should you type in?
Answer:
Step-by-step explanation:
1/4 = (1 divided by 4) = 0.25
To convert 1/4 pound of saffron to a decimal for an ordering system, divide 1 by 4, resulting in 0.25. Therefore, the appropriate decimal to enter is 0.25.
The question involves converting a fraction to a decimal for the purpose of entering an order quantity in a system. In this case, we want to convert 1/4 pound of saffron into a decimal. To do this, simply divide the numerator (1) by the denominator (4). Therefore, 1 divided by 4 equals 0.25. Hence, you should type 0.25 into the ordering system to order 1/4 pound of saffron.
A pentagon the Measures of four of its angle are shown bellow: what is the value of x?
Answer:
See below.
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
A pentagon has 5 sides, so for a pentagon, n = 5.
(n - 2)180 = (5 - 2)180 = 3(180) = 540
The sum of the measures of the angles of a pentagon is 540.
You don't show the measures of the 4 angles that are known, so to answer the question, add the 4 given measures and subtract the sum from 540.

The length of DZ is 4 units ⇒ 3rd answer
Step-by-step explanation:
Triangle X Y Z is cut by line segment C D, where
C lies on side XY and D lies on the side YZThe length of C D is 15The length of X Z is 18The length of C Y is 25The length of Y D is 20C D and X Z are parallelCX = 5 unitsWe need to find the length of DZ
In Δ XYZ
∵ C ∈ XY and D ∈ YZ
∵ CD // XZ
∴ m∠YCD = m∠YXZ ⇒ alternate angles
∴ m∠YDC = m∠YZX ⇒ alternate angles
In Δs YCD and YXZ
∵ m∠YCD = m∠YXZ
∵ m∠YDC = m∠YZX
∵ ∠Y is a common angle
∴ Δ YCD is similar to Δ YXZ by AAA postulate
- There is a constant ratio between their corresponding sides
∴ [tex]\frac{YC}{YX}=\frac{CD}{XZ}=\frac{YD}{YZ}[/tex]
∵ YC = 25 units
∵ CX = 5 units
∵ YX = YC + CX
∴ YX = 25 + 5 = 30 units
∵ YD = 20 units
∵ YZ = YD + DZ
∴ YZ = 20 + DZ
Let us use the ratio of the corresponding side
∵ [tex]\frac{YC}{YX}=\frac{YD}{YZ}[/tex]
∴ [tex]\frac{25}{30}=\frac{20}{20+DZ}[/tex]
- Simplify [tex]\frac{25}{30}[/tex] by dividing up and down by 5
∵ [tex]\frac{25}{30}=\frac{5}{6}[/tex]
∴ [tex]\frac{5}{6}=\frac{20}{20+DZ}[/tex]
- By using cross multiplication
∴ 5(20 + DZ) = 6(20)
∴ 100 + 5 DZ = 120
- Subtract 100 from both sides
∴ 5 DZ = 20
- Divide both sides by 5
∴ DZ = 4 units
The length of DZ is 4 units

• They must produce at least 10 and not more than 30 graphing calculators per day.
• Each day, the number of graphing calculators cannot exceed twice the number of scientific calculators produced.
• The number of scientific calculators cannot exceed 40 per day.
If x is the number of graphing calculators produced daily and y is the number of scientific calculators produced daily, what are the constraints ?
10 ≤ x ≤ 30, x < 2y, x < 40.
Solution:
Given x is the number of graphing calculators produced daily and
y is the number of scientific calculators produced daily.
Step 1: A company produce atleast 10 and not more than 30 graphing calculators per day.

Final answer:
Joshua has 114 dimes and 1160 pennies in his piggy bank. This was determined by setting up a system of equations based on the values of the coins and the given relationship between the number of dimes and pennies.
Explanation:
The problem presented is a typical algebraic word problem that requires setting up equations based on the given information about dimes and pennies. We are told that the total value of the coins is $23.00 and that the number of pennies is 20 more than 10 times the number of dimes. To solve the problem, we need to use the fact that the value of a dime is 10 pennies, and then set up a system of linear equations to find the number of each type of coin.
Step-by-Step Explanation
Let's denote the number of dimes as d and the number of pennies as p.The value of the dimes is 10d pennies since each dime is worth 10 pennies.The total value of the dimes and pennies is 23 dollars or 2300 pennies (since 1 dollar equals 100 pennies).According to the problem, p = 10d + 20.The equation representing the total value is thus 10d + p = 2300.Substituting p from the first equation into the second gives us: 10d + (10d + 20) = 2300.Simplifying this equation, we get 20d + 20 = 2300.Subtracting 20 from both sides, we get 20d = 2280.Dividing both sides by 20, we find out that d = 114.Substituting d back into the first equation to find p, p = 10(114) + 20 which gives us p = 1160.Thus, Joshua has 114 dimes and 1160 pennies in his piggy bank.

is 1.85 percent of the unpaid balance. What is the finance charge?
Answer:
The finance charge is $6.96.
Step-by-step explanation:
Given:
Dudley Greene's charge account statement shows an unpaid balance of $376.00.
The monthly finance charge is 1.85 percent of the unpaid balance.
Now, to find the finance charge.
Unpaid balance = $376.00.
Finance charge = 1.85% of unpaid balance.
So, to get the finance charge:
1.85% of $376.00.
[tex]=\frac{1.85}{100} \times 376.00[/tex]
[tex]=0.0185\times 376.00[/tex]
