3. Tarzan went to the plant nursery and bought a tree that was initially 90 feet tall for his monkey friends to climb on.
After planting the tree, Tarzan made a table to record the height, h, of the tree, t years after it was planted. “Zero” is the time when he planted the tree.
t 0 1 2 3 4
h 90 105 120 135 150
(a) Use words to describe the relationship between the height of the tree and the number of years since it was planted.
(b) Write a two-variable equation to illustrate the relationship between the height of the tree and the number of years since it has been planted.
Answer:
ok im convuzed how do you buy a 90ft tree cuz that sounds fun

Christina has 50 coins consisting of quarters and dimes. The coins combined value is $9.50. Write a system of equation to determine how many quarters and dimes Christina has.
Answer:
Christina has 30 quarters and 20 dimes.
Step-by-step explanation:
Given that a quarter is worth 0.25 dollars and a dime is worth 0.10 dollars, if Christina has 50 coins and these add up to a total of $ 9.50, to determine the number of quarters and dimes that she has in her possession, the following calculation must be carried out, taking into account that the difference between a quarter and a dime is 0.15 dollars:
50 x 0.25 = 12.5
12.5 - 9.5 = 3
Thus, the difference between the value that Christina has and the value that she would have if all of her coins were quarters is 3 dollars. Thus, since 0.15 x 20 equals 3, of the 50 coins Christina has, 30 are quarters and 20 are dimes.
This is confirmed through the following equation:
30 x 0.25 + 20 x 0.1 = X
7.5 + 2 = X
9.5 = X
26 _Is this number rational or irrational? 0.5287593593593593 Explain why?
Answer:
Irrational means it can not be written completely. If there was a line above the last number/the number was infinite, it would be irrational. But because it stops, its not irrational. It can be written as a fraction, so it is rational.

The slope of the line y - 4x = -2 is 4.
False
O True
Answer:
True
Step-by-step explanation:
Set up the problem in slope intercept i.e y = mx + b. Add 4x to both sides to create y = 4x -2. Any number or fraction in the m part is the slope. So the slope is 4.
True, the slope of the line y - 4x = -2 is 4.
The equation of a line in slope-intercept form with slope m is,
y = mx + c
Where 'c' is the y-intercept of the line.
Given that,
The equation of a line is,
y - 4x = - 2
Now it can be written in a slope-intercept form as,
y - 4x = - 2
Add 4x on both sides,
y - 4x + 4x = - 2 + 4x
y = 4x - 2
By comparing with slope - intercept of the equation,
Slope (m) = 4
Therefore, the statement is true.

Santiago starts a savings account with $20. Each month he deposits $15 more into the account. Santiago wants to save a least $80. Write an inequality that represents this situation.
Answer:
$20 + $15m ≥ $80
Step-by-step explanation:
He starts off with $20.
He adds $15 each month, so $15m.
He wants to save at least $80, which means greater than or equal to $80. So, you use this symbol: ≥
Put it all together.
$20 + $15m ≥ $80

Step-by-step explanation:
All radioactive isotopes decay exponentially, the mass of the isotope as a function of time ([tex]m(t)[/tex]), measured in grams, is defined by:
[tex]m(t) = m_{o}\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]m_{o}[/tex] - Initial mass of the isotope, measured in grams.
[tex]k[/tex] - Decay rate, measured in [tex]\frac{1}{min}[/tex] or [tex]\frac{1}{day}[/tex] or [tex]\frac{1}{yr}[/tex].
[tex]t[/tex] - Time, measured in minutes, days or years.
We define the decay rate in terms of half-life by using the following expression:
[tex]k = \frac{\ln 2}{t_{1/2}}[/tex] (2)
Where [tex]t_{1/2}[/tex] is the half-life of the isotope, measured in minutes or years.
Now we proceed to determine the missing values:
a) Polonium-200 ([tex]t_{1/2} = 11.5\,min[/tex])
[tex]k = \frac{\ln 2}{11.5\,min}[/tex]
[tex]k \approx 0.0602\,\frac{1}{min}[/tex]
b) Lead-194 ([tex]t_{1/2} = 10.7\,min[/tex])
[tex]k = \frac{\ln 2}{10.7\,min}[/tex]
[tex]k \approx 0.0648\,\frac{1}{min}[/tex]
c) Iodine-125 ([tex]k = 0.0115\,\frac{1}{day}[/tex])
[tex]t_{1/2} = \frac{\ln 2}{k}[/tex]
[tex]t_{1/2} = \frac{\ln 2}{0.0115\,\frac{1}{day} }[/tex]
[tex]t_{1/2} \approx 60.274\,days[/tex]
d) Kryption-75 ([tex]k = 0.161\,\frac{1}{min}[/tex])
[tex]t_{1/2} = \frac{\ln 2}{k}[/tex]
[tex]t_{1/2} = \frac{\ln 2}{0.161\,\frac{1}{min} }[/tex]
[tex]t_{1/2}\approx 4.305\,min[/tex]
e) Strontium-79 ([tex]t_{1/2} = 2.3\,min[/tex])
[tex]k = \frac{\ln 2}{2.3\,min}[/tex]
[tex]k \approx 0.3\,\frac{1}{min}[/tex]
f) Uranium-229 ([tex]t_{1/2} = 58\,min[/tex])
[tex]k = \frac{\ln 2}{58\,min}[/tex]
[tex]k \approx 0.0120\,\frac{1}{min}[/tex]
g) Plutonium-239 ([tex]t_{1/2} = 24100\,yr[/tex])
[tex]k = \frac{\ln 2}{24100\,yr}[/tex]
[tex]k \approx 2.876\times 10^{-5}\,\frac{1}{yr}[/tex]

Answer: 1) $0.76 per serving of pumpkin pie
2) 64 people
3)
1 1/3 cup sweet potatos
2 tablespoons + 2 teaspoons of white sugar
1 egg
1/4 teaspoon of salt
2 tablespoons of butter
2 tablespoons + 2 teaspoons of milk
1/4 teaspoon of vanillia
2 tablespoons + 2 teaspoons of brown sugar
1 tablespoon + 2 1/3 teaspoons flour
2 tablespoons + 2 teaspoons of peacans
Step-by-step explanation:
1) the total cost of the ingredients needed to prepare a pumpkin pie = $1.50 + ($2.59 / 6) + ($5.99 / 6) + $1.25 + ($3.79 / 2) = $6.075
if we cut 8 servings per pie, then the cost per serving = total cost of the pie/number of servings = $6.075 / 8 = $0.759375 ≈ $0.76 per serving of pumpkin pie
