Answer:
a(t) = 487(1/2)^(t/36)a(5) = 442.302 kgStep-by-step explanation:
The exponential function for half-life problems is easily written using 1/2 as the base of the exponent.
present value = (initial value) × (1/2)^(t/(half-life))
Then the amount (a) remaining after t days is ...
a(t) = 487 × (1/2)^(t/36)
__
After 5 days, the amount remaining is ...
a(5) = 487×(1/2)^(5/36) ≈ 442.302 kg
_____
Some folks like their exponential function to be written using e as the base for the exponent. Here, that would be ...
a(t) = 487·e^(-0.019254t)
where the constant in the exponent is -ln(2)/36.

For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2
which tile's side lengths will Dorian need to estimate?
Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm

The sum of 3 consecutive odd integers is 36. Whal
consecutive odd integers
[tex]\huge\pink{Answer}[/tex]
Any odd number can be represented with 2n+1 where n is a whole number. Also, since the next consecutive number will be even (2n+1+1), then the next consecutive odd number must be 2n+1+2, or 2n+3. Since consecutive odd numbers are separated by 2, then the previous odd number should be 2n-1. So:
2n-1+2n+1+2n+3=366n+3=366n+3-3=36-36n/3=33/32n=11Now in order to find three odd consecutive numbers that will sum to 36, you must be able to divide 11 evenly by 2, and have a whole number as a result. This is impossible, so there aren't any 3 odd numbers that will sum to 36.

Find x so that l is parallel to m.
Answer:
Step-by-step explanation:
(10x + 17)° = 87° + 5x° (This is because of the rule of corresponding angles)
=> 10x° = 87° + 5x° - 17°
=> (10x - 5x)° = 87° - 17°
=> 5x° = 70°
=> x° = ( 70/5 )°
=> x° = 14°
Therefore x = 14°

Franco begins to save for a new Lego set that costs $65. His parents gave him $35 towards the cost
and he plans to save $5 per week. Define all unknown variables. Write an equation modeling the total
amount he has saved.
Answer:
65-35=30
30 divided by 5 = 6
Step-by-step explanation:
First you have to subtract 65-35, which equals 30.
Then the problem says he plans to save 5 each week. That means he should get his lego set in 6 weeks, because 30 divided by 5 = 6
65-35=30
30 divided by 5 = 6

Answer:
193.95 Canadian dollars
Step-by-step explanation:
Given: Each U.S. Dollar is worth 1.293 Canadian dollars and each Canadian dollar is worth 0.773 U.S. Dollar.
To find: Value of 150 U.S. dollars in terms of Canadian dollars
Value of 1 U.S. dollar = 1.293 Canadian dollars
To find 150 U.S. dollars in terms of Canadian dollars, multiply 150 by 1.293
Value of 150 U.S. dollars in terms of Canadian dollars = 150 × 1.293 = 193.95 Canadian dollars

what is the result of (4³)² × (¼)²
Answer:
256
Step-by-step explanation:
By using power of a power rule, the result of [tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex] is 256.
What are exponential formulas?Exponents formulas refer to the formulas that help solve exponents. Exponent of a number is represented in the form: [tex]x^{n}[/tex], meaning x is multiplied by itself for n times. Here,
x is called the "base"
n is called the "exponent" or "power"
[tex]x^{n}[/tex] is read as "x to the power of n" (or) "x raised to n"
Power of a power rule : [tex](a^{m} )^{n}=a^{mn}[/tex]
Given exponential expression
[tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex]
[tex](4^{3} )^{2}[/tex] is in the form of power of a power rule [tex](a^{m} )^{n}=a^{mn}[/tex]
= [tex]4^{6}[/tex] × [tex]\frac{1}{4^{2} }[/tex]
= [tex]4^{4}[/tex] × [tex]4^{2}[/tex] × [tex]\frac{1}{4^{2} }[/tex]
= [tex]4^{4}[/tex]
= 256
The result of [tex](4^{3} )^{2}[/tex] × [tex](\frac{1}{4} )^{2}[/tex] is 256.
