The firstone I guess I'm not that sure tbh
Hope it’s right
Best luck with your studying
Answer:
0.0000019 in.
Step-by-step explanation:
I'm not exactly sure on this, but you would convert the 365 days in a year to 8,760 hours, which would be 525,000 minutes. Since there are 24 hours in a day, I multiplied 365 days by 24 hours, which is how I got 8,760 hours in a year. Then I got 525,000 minutes in a year by multiplying 8,760 hours by 60 minutes. I converted the 365 days in a year to minutes because the question only gives you how many minutes there are.
With this information, I created a proportion. 1.5 inches over 525,000 minutes equals x over 0.05 (I decided to use the 0.05 of a minute rather than the 3 seconds so I didn't have to convert the 525,000 minutes to seconds. 0.05 was the number given in the question).
After cross-multiplying, I got 0.075 from 1.5 times 0.05 and divided 0.075 from 525,000. 525,000 divided by 0.075 is 0.0000019 inches.

Answer:
Its A
Step-by-step explanation:
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
