A plant measures 10 cm and increases in height by .02 percent each day, upon conclusion it measures 11.04 cm. What is a reasonable domain to plot the growth function?
Answers
Answer:
the correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.
Step-by-step explanation:
I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).
Slope = (20 - 10)/(50 - 30) = 1/2

there?
21. Determine if the values in the table are
Answers
Answer:
20 girls.
Step-by-step explanation:
If 32 divided by 8 is 4, then 4x8= 32.
We use this equation to find out how many girls there are. 5x4 equals 20, so there are 20 girls at summer camp.
A school carnival sold 24 early-admission tickets and 72 regular tickets. What percentage of the tickets sold were early-admission tickets? Write your answer using a percent sign (%).
Answers
Answer:
25%
Step-by-step explanation:
add both kinds of tickets first to get the total
24 early admission + 72 regular = 96 total tickets
then divide 24 early tickets by 96 total tickets to get the decimal, then multiply by 100 to get percent
[tex]\frac{24}{96} = 0.25 * 100 = 25[/tex]%

Problema Solution
There were 155 people at the basketball game. Tickets for the game are $2.50 for students and $4 for adults. If the total money received for admission was $492.50, how many students and adults attended the game?
Answer provided by our tutors
let
s = the number of student tickets sold
a = the number of adult tickets sold
there were 155 people at the basketball game
s + a = 155
the total money received for admission was $492.50
2.50s + 4a = 492.50
by solving the system of equations
s + a = 155
2.50s + 4a = 492.50
we find
s = 85 students
a = 70 adults

Given the zeros of the function f (x) = x4 + 3x3 – 28x², identify whether the zero is a bounce or
cross.
Answers
f(x) = x^4 + 3x^3-28x^2
Factorising, we get
f(x) = x^2(x+7)(x-4)
Therefore, there is a double root at x = 0 and singular roots at x = -7 and 4
double roots tend to bounce, kind of like the standard quadratic y = x^2
singular roots tend to cross, kind of like a straight line on a graph, y = mx + b
Therefore, it bounces at x = 0, and crosses at x = -7 and 4
In general, a root raised to an even power bounces, and a root raised to an odd power crosses.
Membership at the YMCA costs $15 per month plus $80 to sign-up. Blink costs $29 per month but is free

Answers
Let months be x
[tex]\\ \sf\longmapsto 80+15x=29x[/tex]
[tex]\\ \sf\longmapsto 29x-15x=80[/tex]
[tex]\\ \sf\longmapsto 14x=80[/tex]
[tex]\\ \sf\longmapsto x\approx 6months[/tex]
Answer:
43 months in ymca including the $80 sign up fee is equal to 25 months in blink
Step-by-step explanation:
$725 divided by $29 =25 months
$ 725 - $80 sign up = $645 .
Now we divide this by $15.
$645 divided by 15= 43 months

-16t^2+80t+4=100
Answers
Answer:
Step-by-step explanation:
Good job on creating a testable equation.
Maybe you need to know what to do with it.
If we can find a real solution or two, then the projectile will reach the 100 ft altitude. (I'm fairly certain it will given that high initial velocity)
If we cannot find a real solution, then the rocket will fail to reach the altitude goal.
-16t² + 80t + 4 = 100
we will want a zero on the right hand side, so subtract 100
-16t² + 80t - 96 = 0
we can simplify even further by dividing everything by -16
t² - 5t + 6 = 0
which can be factored
(t - 3)(t - 2) = 0
so either
t = 3 s
or
t = 2 s
So the projectile reaches the 100 ft level twice,
at two seconds after launch while rising and
at three seconds after launch while falling.
Lets see what happens when we set the goal a bit higher, say 108 ft
-16t² + 80t + 4 = 108
-16t² + 80t - 104= 0
-2t² + 10t - 13 = 0
not easily factored so let's use quadratic formula
t = (-10 ±√(10² - 4(-2)(-13))) / (2(-2)
t = (-10 ±√-4) / -4
As √-4 = 2i is an imaginary number, there are no real solutions and the projectile will not reach 108 ft.

Explain how to compare decimals. Use the numbers 6.75 and 6.732 to

Answers
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732

How do I show my work for solving the radius of a circle if the area is 78.5 cm^2
(I already know the answer is 5 cm)
Answers
9514 1404 393
Answer:
radius = 5 cm
Step-by-step explanation:
The point of "show your work" is to have to do exactly that. If you know the answer to the problem, you are being requested to show how you got it. If you got it by using a web calculator, then show your input and its result.
__
If you worked the problem yourself, you probably did it by filling in numbers in the equation for the area of a circle:
A = πr²
78.5 = 3.14×r²
Dividing both sides by 3.14 gives the square of the radius:
78.4/3.14 = r² = 25
Taking the positive square root gives the radius:
r = √25 = 5
The area is in square centimeters, so the radius is in centimeters:
radius = 5 cm

Answer:
50x+20=ur mom
Step-by-step explanation:
Answer:
t = 20 + .50m
m = number of miles travelled
t = total cost
Step-by-step explanation:
t represents the total cost and m represents the number of miles travelled. Since it costs .50 per mile, you would do .50m so that you could calculate the cost based on the number of miles and since the truck at first cost 20 dollars, you would add that to the equation to. This gives you t = 20 + .50m.
