t The function f(t) = 390(1.0085) 365 represents the change in a quantity over t days. What does the constant 1.0085 reveal about the rate of change of the quantity?
The function is (growing/decaying) exponentially at a rate of _% evey ___.
Answer: The function is *growing* exponentially at a rate of *0.85%* every *year*
Step-by-step explanation:
The function is growing exponentially at a rate of 0.85% every year.
What is the exponential decay equation?The exponential decay equation is given by:-
y = (1 ± r)ⁿ
Where r is the rate of decay and A is the initial amount and n is the time period.
The function is given in the question below as:
The function f(t) = 390(1.0085)³⁶⁵ ....(i)
This represents the change in quantity over t days.
As per the given exponential decay equation,
⇒ f(t) = 390(1.0085)³⁶⁵
We can above function rewrite as:
⇒ f(t) = 390(1 + 0.0085)³⁶⁵
⇒ f(t) = 390(1 + 0.85/100)³⁶⁵
⇒ f(t) = 390(1 + 0.85%)³⁶⁵
Compare to the standard exponential decay equation, and we get
⇒ r = 0.85%
Therefore, the function is growing exponentially at a rate of 0.85% every year.

Event to consider: There is a 50 percent chance that you drive up to a stop light and it is yellow.
True
False
Answer:
False
Step-by-step explanation:
Usually there are three different lights on a stop light to consider
With three lights, the chance that the light is yellow would be about 33.334%
If it were to be a 50/50 chance then there would only be two lights
Two equivalent fractions for 2/3
Answer:
2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3. Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.

Suppose that when a car goes over a bump, the impact hat must be absorbed by the suspension is directly proportional to the square of the car's speed. Of a car going 12 mph receives 4000 units of impact, ow much impact will a car received at 30 mph
Answer:
10000 units of impact
Step-by-step explanation:
From the above question:
12 mph = 4000 units of impact
30 mph = x units of impact
Cross Multiply
12 mph × x units = 30 mph × 4000 units
x units = 30 mph × 4000 units/12 mph
x units = 10000 units of impact.
Therefore, 30 mph receives 10000 units of impact

Solve 3[-x + (2 x + 1)] = x-1.
X=
DONE
Answer:
x=−2
Step-by-step explanation:
Simplify both sides of the equation.
3(−x+2x+1)=x−1
Distribute
(3)(−x)+(3)(2x)+(3)(1)=x+−1
−3x+6x+3=x+−1
Combine Like Terms
(−3x+6x)+(3)=x−1
3x+3=x−1
3x+3=x−1
Subtract x from both sides.
3x+3−x=x−1−x
2x+3=−1
Subtract 3 from both sides.
2x+3−3=−1−3
2x=−4
Divide both sides by 2.
2x/2=−4/2
x=-2

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?
Answer:
200 litres
Step-by-step explanation:
let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is
g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation
To find k use g = 25, d = 100 and s = 100, then
25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )
0.025 = k
g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation
When d = 1000 and s = 64, then
g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200

5n = 36
Solve for n
Please show steps thanks so much
Answer:
n = 7.2
Step-by-step explanation:
I just divided both sides by 5.
5n (÷ 5) = 36 (÷ 5)
n = 7.2 or 7 [tex]\frac{1}{5}[/tex]
You can choose between using the decimal or the fraction.
Answer:
n=7.2
Step-by-step explanation:
=> 5n=36
=> 5n/5 =36/5 [Divide by 5 on both the sides]
=> n=7.2

responder: 8,75
Cada dimensión será de 8,75 porque si la longitud es de 25 m de largo y el ancho es 10, si los sumamos y obtendremos 35. Así que 35 dividido entre 4 es 8,75

-9x + 6y = 18
y = -6
Answer:
the answer should be x = -6
Step-by-step explanation:
-9x + 6y = 18
-9x + 6(-6) = 18
-9x - 36 = 18
-9x - 36 + 36 = 18 + 36
-9x = 54
-9x ÷ -9 = 54 ÷ -9
x = -6

Ben sells homemade cards at a craft fair. He wants to earn more than $50 at the fair. He sells his cards for $2 and he has already earned $36. How many cards foes he need to sell to reach his goal? Write and solve an inequality.
Answer:
He must sell 8 cards to reach the minimum goal.
Step-by-step explanation:
Giving the following information:
He wants to earn more than $50 at the fair.
He sells his cards for $2 and he has already earned $36.
First, we need to calculate the money required to reach the minimum goal:
51 - 36= $15
Now, we write the inequality:
2*x >15
x= number of cards sold.
x>15/2
x> 7.5
He must sell 8 cards to reach the minimum goal.
The sum of two numbers is 44 and the difference is 2 What are the numbers
Answer:
21 & 23
Step-by-step explanation:
44 ÷ 2 = 22
The two numbers are going to be close to 22.
21 + 23 = 44
32 - 21 = 2
Answer:
You can try to write two equation from the question
Call x a number and y the other.
The sum of them is 44: x + y = 44
The difference (substract) is 2: x - y = 2
System:
x+y=44
x-y = 2
You can just sum both equations, as the y disappear:
2x = 46
x =46/ 2 = 23
We replace in the equation:
23 - y = 2
y = 21
And we know the numbers are 21 and 23
