Answers
The correct answers are 1008 hours are 6 weeks and 5 weeks are 840 hours.
What is the ratio?The ratio indicates how many times one number is to the other number.For example, if you have 4 chocolates and 2 cakes the ratio of the chocolates and the cake will be 2:1 which means that chocolate is 2 times then the cake.
It is given that 168 hours is equal to 1 week. we need to find 1008 hours has how many weeks and 5 weeks has how many hours.
1.) 1008 hours has how many weeks
168 hours = 1 week
1 hour = 1 / 168 weeks
1008 hours = 1008 / 168 = 6 weeks
So 1008 hours has 6 weeks
2.) 5 weeks has how many hours.
1 week = 168 hours
5 weeks = 5 x 168 hours
5 weeks = 840 hours
So 5 weeks will have 840 hours.
Therefore correct answers are 1008 hours are 6 weeks and 5 weeks are 840 hours.

You purchased a new car for $32,000. The value
of the car decreases by 12% each year. Which
function could be used to model the value of the
car V after years?
a. V(t)=32,000(1+0.12)'
b. V()=32,000(1 -0.12)'
c. V(t)=32,000(0.12)'
d. V(t)=32,000 - 0.12r
Answers
The function that could be used to model the value of the car V after years is V(t) = 32000(1 - 0.12)^t
How to determine the function?The given parameters are:
Initial value, a = 32000
Rate, r = 12% --- depreciation rate
Since the value of the function decreases with time, the equation of the exponential function would be:
V(t) = a(1 - r)^t
So, we have:
V(t) = 32000(1 - 12%)^t
Express as decimal
V(t) = 32000(1 - 0.12)^t
Hence, the function that could be used to model the value of the car V after years is V(t) = 32000(1 - 0.12)^t

A radioactive compound with mass 470 grams decays at a rate of 3% per hour. Which
equation represents how many grams of the compound will remain after 6 hours?
Submit Answer
O C = 470(0.03)
O C = 470(0.7)
O C = 470(1 + 0.03)
C = 470(1 – 0.03)
Answers
After 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.
What is exponential decay?During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We know the decay can be as:
[tex]\rm C = a(1-r)^t[/tex]
We have:
a = 470 grams
r = 3% = 0.03
t = 6 hours
[tex]\rm C = 470(1-0.03)^6[/tex]
C = 391.49 grams
Thus, after 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.

Answers
Answer:
30 - 12x or 6(5 - 2x)
Step-by-step explanation:
Given expression:
4[5 + (-3x)] + 10First, let us simplify the expression inside the parentheses;
⇒ 4[5 + (-3x)] + 10⇒ 4[5 - 3x] + 10Then, let us open the parentheses by simplifying the distributive property;
⇒ 4[5 - 3x] + 10⇒ 20 - 12x + 10Finally, let us simplify the expression by adding 10 to 20.
⇒ 20 - 12x + 10⇒ 30 - 12x[Optional] Factor the expression by putting the expression in parentheses.
⇒ 30 - 12x⇒ (30 - 12x)Since 6 is divisible to all the terms in the expression, we can divide 6 to all the terms in the expression and take "6" outside the parentheses.
⇒ 6(30/6 - 12x/6)⇒ 6(5 - 2x)Therefore, the simplified expression is 30 - 12x or 6(5 - 2x).

Answer:
step 2
and then also in step 3 compensating the error in step 2
Step-by-step explanation:
I think I just answered this for another post.
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
so, step 1 is correct :
sin(A - 3pi/2) = sin(A)cos(3pi/2) - cos(A)sin(3pi/2)
but step 2 suddenly and incorrectly switched that central "-" to a "+".
yes, sin(3pi/2) = -1, but that is still an explicit factor in step 2. so it was not used to flip the central operation from subtraction to addition, and therefore this change was a mistake.
then, in step 3, another error was made by just ignoring the "-" sign of "-1" and still keeping the central "+" operation. this error compensated for the error in step 2 bringing us back by pure chance to the right result.
