The height of a tree is 8.2 meters.
What is the tree's height in centimeters?
Answer:
820 centimeter :3
Step-by-step explanation:
8.2 meters
move the decimal back twice because of KiloHecaDecaBase (m,l,g)DeciCentiMilli
As we know 1 meter is equal to 100 centimeters so the height of the tree 8.2 meters is equal to 820 meters
What is unit conversion?The same attribute is expressed using a unit conversion but in a different unit of measurement.
For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.
Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.
A conversion factor is a mathematical equation that facilitates an equal exchange of feet for chains.
Given, The height of a tree is 8.2 meters, now we know 1 meter is equal to 100cm so to convert some quantity from meters to centimeters we multiply by 100.
∴ 8.2 meters is equal to (8.2×100) = 820 centimeters.

How do you do this, because I really do not know how to do this and plz explain how to do this
Answer:
A
Step-by-step explanation:
the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5
so the answer should be
-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity
when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.
for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)

2) a. (30, 32) and (18, 16)
[tex] m = \dfrac{y_1 - y_2}{x_2 - x_1} [/tex]
[tex] m = \dfrac{32 - 16}{30 - 18} [/tex]

Answer:
$50,000 in stocks
$40,000 in bonds
$25,000 in CDs
Step-by-step explanation:
Let c represent the amount invested in CDs. Then the amount invested in bonds is (c+15000) and the amount invested in stocks is (115000 -c -(c+15000)) = (100000 -2c). The total interest earned is ...
0.04c +0.053(c +15000) +0.062(100,000 -2c) = 6220
-0.031c +795 +6200 = 6220
-0.031c = -775 . . . . . . . . . . . . . . . subtract the left-side constants
c = 25000 . . . . . . . . . . divide by the coefficient of c
c+15000 = 40000 . . . . bonds

Tony and Ricky spend a certain amount of money from their accounts each week at a pet shelter.
The table shows the relationship between the amount of money (y) remaining in Tony's account and the number of weeks (x):
Function 1:
Number of Weeks
(x) Amount Remaining (dollars)
(y)
1 30
2 24
3 18
4 12
The equation shows the relationship between the amount of money, y, remaining in Ricky's account and the number of weeks, x:
Function 2:
y = –7x + 30
Which statement states and explains which function shows a greater rate of change?
Function 1, because Tony spends $6 each week and Ricky spends –$7 each week
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Function 1, because Tony spends $18 each week and Ricky spends $23 each week
Function 2, because Ricky spends $30 each week and Tony spends $18 each week
Answer:
Function 2, because Ricky spends $7 each week and Tony spends $6 each week
Step-by-step explanation:
You find the rate of weekly rate of change by calculating the difference of the amount changing each week:
24 - 30 = - 6
18 - 24 = - 6
12 - 18 = - 6
As you see the rate of change is constant: - 6 dollars per week. This means that Tony is spending 6 dollars every week
Function 2: y = –7x + 30
The rate of change is the slope (m) of the linear function, and this is the coefficient of the independent variable, x.
This equation is written in slope intercept form (y= mx+b)
Then the rate of change is - 7 dollar per week. This means Ricky spends 7 dollars every week.
Now you know that the two rates are constant and that the second function shows a steeper decreasing.
