Answer:
<em>b = 50√c</em>
Step-by-step explanation:
If b varies directly as the square root of c, this is expressed as;
b∝√c
b = k√c
k is the constant of proportionality
Given b = 100 and c = 4
100 = k√4
100 = 2k
k = 100/2
k = 50
Substitute k = 50 into the original expression:
Recall that: b = k√c
b = 50√c
<em>hence equation that can be used to find other combinations of b and c is b = 50√c</em>
ok for number 2.) 2+8+1+5+1+3+1+7+5+4+3+1=41 and 41 divided by the number of number which is 12= 3.41666666667
the mean for number 2 is 3.41666666667.
for the median you put the number from least to greatest, like so:
1, 1, 1, 1, 2, 3, 3, 4, 5, 5, 7, 8.
The middle is 3 and 3 so 3+3 divided by 2 is 6 so the median is 6.
I cant do mode but range is 8-1 divided by 2
Answer:200 in ^3
Step-by-step explanation:
The answer would be (3,-1) because it is reflected
Answer:
The car will have lost it's total value by 2007.
Step-by-step explanation:
If initially the car was valued at 44,000$, and after 9 years it's value dropped to 15,000$, we can say that the car's value dropped in 29,000$. If we suppose that the drop is the same every year, we can say that it was of 3,222,2$ by each year.
This amount of money is the 7,3% of the initial value of the car (I multiplied 3,222,2 x 100 : 44,000).
a) The annual rate of change was of 7,3%.
b) There are 14 years between 1993 and 2007. If we multiply 7,3% by 14, we get that the car lost 102,2% of it's initial value.
