Answer:
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
Step-by-step explanation:
Using the formula :
S = 20,000 (1 + 0.08)^y to estimate ;
S = number of subscribers ; y = years
The expression : (1 + 0.08)^y
0.08 = 0.08 * 100% = 8%
(1 + 0.08)^y represents a continous growth or increase in the number of subcsribers by 8% over the number of subscribers the preceeding year

15.5 meters of wood.
Step-by-step explanation:
Find the perimeter of the box.
2(1.50)+2(6.25)=15.5
Answer:
15.5 m of wood
Step-by-step explanation:
The perimeter of this 1.5 m by 6.25 m frame is a measure of the length of wood needed. Here P = 2(1.5 m) + 2(6.25 m) = 3 m + 12.5 m, or 15.5 m

Denzel wants to work out the density of a block of wood the block of wood is in the shape of the cuboid
Answer:
[tex]Density = 1.094g/cm^3[/tex]
Step-by-step explanation:
Given
[tex]Length = 17.7cm[/tex]
[tex]Width = 8.3cm[/tex]
[tex]Height = 13.0cm[/tex]
[tex]Mass = 2090g[/tex]
See attachment
Required
Determine the density of the wood
First, we calculate the volume of the wood.
[tex]Volume = Length * Width * Height[/tex]
Substitute values for Length, Width and Height
[tex]Volume = 17.7cm * 8.3cm * 13.0cm[/tex]
[tex]Volume = 1909.83cm^3[/tex]
The density is:
[tex]Density = \frac{Mass}{Volume}[/tex]
[tex]Density = \frac{2090g}{1909.83cm^3}[/tex]
[tex]Density = 1.094g/cm^3[/tex] --- approximated
Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written

f(x) = - 3x + 4
f(x) = - *x+
f(V) = - 3y + 4
Answer:
b) y = f(x) = -3x+4
Step-by-step explanation:
Explanation
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x
[tex]y = \frac{-9x+12}{3}[/tex]
y = -3x+4
The function represented by y = -3x+4
Describe and correct the error in solving the following rational equation , plz help!!!!!
First of all, x cannot ever equal -1 because if it does then in the original equation you'd be dividing by 0, which is not possible. anything divided by 0 is undefined.
I think the error was in the second step: x(x+1) = 2(x+1) because they didn't need to go from the first step to there. I'm assuming they multiplied both sides of the equation with (x+1) to get rid of the fraction, but since both sides have (x+1) as the denominator the (x+1) would've cancelled out instead of multiplying with the numerator.
Correction:
[tex]\frac{x}{x+1} = \frac{2}{x+1}\\(\frac{x+1}{1}) (\frac{x}{x+1}) = (\frac{2}{x+1})(\frac{x+1}{1}) \\x = 2[/tex]
as u can see, in the second step of this correction, the (x+1)s on both sides cancel out so only the numerators remain.

Step-by-step explanation:
Rosanne and Jimmy are looking to purchase a house. They found one that they like, but the inspection report showed that there was a problem. The foundation has termites. The report states that the foundation of a house has 1200 termites. The termites grow at a rate of about 2.4% each day.
A. Formulate an equation in exponential form that represents the termite situation.
The formula for exponential growth or increase =
P(t) = Po (1 + r)^t
Where:
P(t) = Population growth after time t
P(o) = Initial Population = 1200 termites
r = Growth rate = 2.4% = 0.024
t = Time in days
Hence, the equation in exponential form that represents the termite situation is given as:
P(t) = 1200( 1 + 0.024)^t
B. The extermination is scheduled out for one week from the date of the report. Use your equation to determine how many termites will be in the home at the time of the extermination.
The time of extermination = 1 week
1 week = 7 days
Hence,
t = 7 days
P(t) = Po (1 + r)^t
P(7) = 1200( 1 + 0.024)⁷
P(7) = 1200(1.024)⁷
P(7) = 1416.7099449 termites
Approximately
= 1417 termites

A rental car agency charges $160.00 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $340.00?
Answer:
720 miles
Step-by-step explanation:

340 = 160 + .25m
180 = .25m
m = 180/.25
m = 720

It is a right triangle if the thee sides satisfy the following pythagorean triple rule/theorem, c² = a² + b², where,
c is the longest side = 50
a = 15
b = 49
Let's check:
50² = 15² + 49²
2500 = 2626 (this is not true).
Therefore, the triangle is not a right triangle. The answer is NO.
If f(x) = x², then f(2 – 3i) equals
A. -5
B. -5 – 12i
C. 13 – 12i
D. 13
Answer:
A
Step-by-step explanation:
f(2 – 3i) = (2 – 3i)^2
f(2 – 3i) = (2)^2 + (-3i)^2
f(2 – 3i) = 4 + (9)(-1)
f(2 – 3i) = 4 - 9
f(2 – 3i) = -5
These are functions in another function. The result of the function f(2-3i) is -5-12i
Composite functionsThese are functions in another function. Given the function shown below;
f(x) = x²
In order to determine f(2 – 3i), you will replace as 2 - 3i to have:
f(2 - 3i) = (2 - 3i)²
Expand
f(2 - 3i) = 2² - 12i + 9i²
f(2 - 3i) =4 - 12i - 9
f(2 - 3i) = -5-12i
Hence the result of the function f(2-3i) is -5-12i

27.5
b
62
c
8.5
d
31
Answer:
x = 31
Step-by-step explanation:
The 3 angles in a triangle sum to 180°
Sum the 3 given angles and equate to 180
2x - 7 + 2x + 63 = 180, that is
4x + 56 = 180 ( subtract 56 from both sides )
4x = 124 ( divide both sides by 4 )
x = 31

A car is purchased for 32,000. The value of the car depreciates by 3% per year.
A. Write an exponential function to model the value of the car after t years?
B. What is the value of the car 6 years after it is purchased?
Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860
Emma receives a large box in the mail.The box is 10cm longer than it wide,and the height is 6 cm more than the width
Answer:
y³+16y²+60y
Step-by-step explanation:
Complete question
Emma receives a large box in the mail. The box is 10cm longer than it wide, and the height is 6 cm more than the width. Find the polynomial function for volume of the box
Let the length be x
Let the width be y
let the height be z
If the box is 10cm longer than it wide, then x = y + 10
Also if the height is 6 cm more than the width,
z = y + 6
Volume of the box = xyz
Substitute
Volume of the box = (y+10)(y)(y+6)
Volume of the box = (y+10)(y²+6y)
Volume of the box = y³+6y²+10y²+60y
Volume of the box = y³+16y²+60y
Hence the required polynomial function is y³+16y²+60y

if the simple interest on $5000 for 5 years is $1500 then what is the interest rate?
Answer:
6%
Step-by-step explanation:
Simple interest: A = P(1 + rt)
Solve for r: r = (1/t)((A/P) - 1)
Given:
A = $1500 + $5000 = $6500
P = $5000
t = 5 yrs
r = (1/5)((6500/5000) - 1)
= (1/5)(0.3)
= 0.06
0.06 = 6%

Slope 7; (4,-30 equation
Answer: y=7x-68
Step-by-step explanation: Ok so you would use point slope to slope so plug the points in. y+30=7(x-4) then if you need to convert it further into slope intercept form just simplify and distribute. So y+30=7x-28, subract 30 from both sides to get y=7x-68
Hence, the slope of line is [tex]y=7x-58[/tex].
What is the slope of line?
The slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be easily determined by finding the difference between the coordinates of the points.
The slope is usually represented by the letter ‘m’.
Here given that,
Slope is [tex]7[/tex] and the coordinates of [tex](x,y)=(4,-30)[/tex].
As we know slope of line is
[tex]y=mx+c[/tex]
where [tex]m[/tex] is the slope.
So,
[tex]y+30=7(x-4)[/tex]
Now convert it further into slope intercept form
[tex]y+30=7x-28\\\\y=7x-28-30\\\\y=7x-58[/tex]
Hence, the slope of line is [tex]y=7x-58[/tex].
