Answer:
- C = (5/9)(F -32)
- 50°F ⇒ 10°C
Step-by-step explanation:
Starting with the formula for degrees Fahrenheit, we can solve for degrees Celsius.
F = 32 +9/5C
F -32 = (9/5)C . . . . . subtract 32
(5/9)(F -32) = C . . . . multiply by the inverse of the coefficient of C
The formula for Celsius temperature from Fahrenheit temperature is ...
C = (5/9)(F -32)
__
For F = 50, the corresponding Celsius temperature is ...
C = (5/9)(50 -32) = (5/9)(18) = 10 . . . degrees Celsius
Answer is 9.5- explanation- if u substitute 9.5 in the equation 2(5 x 9.5+ 5 = so multiply 9.5 times 5 which equals 47.5 then multiply by the 2 which equals 95 plus the 2+3=5 - 95+5 equals 100 (sorry I’m bad at explaining)
Answer:
f(x) = 4(1.02)^(7x); spreads at a rate of approximately 2% daily
Step-by-step explanation:
The weekly number of people infected is:
f(x) = 4(1.15)^x
So the daily number of people infected is:
f(x) = 4(1+r)^(7x)
To find the value of the daily rate r, we set this equal to the first equation.
4(1.15)^x = 4(1+r)^(7x)
(1.15)^x = (1+r)^(7x)
(1.15)^x = ((1+r)^7)^x
1.15 = (1+r)^7
1.02 = 1+r
r = 0.02
So the equation is f(x) = 4(1.02)^(7x), and the daily rate is approximately 2%.
If each face has an area of 4 than the side lengths are 2, because area is b•h and 2•2 is 4. Now, volume is length•width•height. All of these will be two because sides are the same in a cube. 2•2•2 is 8, which is your answer
