Answer:
f(x)=−5x−20
Step-by-step explanation:
It's decreasing 5 degrees every hour, which is represented by -5x
You also have to take away the 20 (-20) from where it started.
So, f(x)=−5x−20
Answer:15 is the answer. Product is what you get when you multiply two or more numbers together. In this case, the factors are 3 and 5. 3 x 5 = 15
Answer:
Step-by-step explanation:
<u>Given</u>
- Each deposit = $1500
- Interest rate= 5%
- Time = 4 years
- Compound number = annual
<u>Simple interest account</u>
- B = 1500*(1 + 4*0.05) = 1500*1.2 = $1800
<u>Compound interest account</u>
- B = 1500*(1 + 0.05)^4 = $1823.26
<u>Total balance</u>
- $1800 + $1823.26 = $3623.26
When in aqueous solution, K2CrO4 dissociates into ions. It dissociates into:
K2CrO4 = 2K+1 + CrO4-1
We do as follows:
Molarity = mol / L = 0.38 g/g solution ( 1.37 g/mL ) ( 1 mol / 194.19 g ) ( 1 mol CrO4-1 / 1 mol K2CrO4 ) ( 1000 mL / 1 L ) = 2.68 M

Answer:
5 mph, 11 mph
Step-by-step explanation:
Together, they cover 24 miles in 1.5 hours, so their total rate of speed is ...
(24 mi)/(1.5 h) = 16 mi/h
If s is the rate of the slower jogger, then s+6 is the rate of the faster one. Their total speed is ...
s + (s+6) = 16
2s = 10 . . . . . . . subtract 6
s = 5 . . . . . . . . . divide by 2
s+6 = 11
The rates of the joggers are 5 mph and 11 mph.
