Answer:
all real numbers
Step-by-step explanation:
The domain of <em>any polynomial function</em> is "all real numbers." There is no value of x for which y is undefined.
Answer:
x+7
Step-by-step explanation:
7/y-?/y=x/y
?=x+7
Sorry, I wish I could elaborate more but I can't...
348 miles——>15 gallons of gas
232 miles——-> x
X=(232)(15)/348=10 gallons of gas
In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
= 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
= 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
= 120 miles/ hour
1. Surface area of rectangular prism = 2(lb+bh+lh)
Ans = 2(3*2 + 2*4 + 3*4) = 2(6+8+12) = 52 in^2
Fourth option
2. Length of cube = x feet
Surface area = 6x²
Fourth option
3. Surface area of cylinder = πr(2h+r)
Ans = 3.14*1(2*15+1) = 97.34 cm²
second option
4. Same formula as 1
Ans = 2(10*8 + 8*12 + 10*12) = 2(80+96+120) = 592 in²
fourth option
