321.56
Step-by-step explanation:
volume = (4/3) * π * r³
Answer:
21
Step-by-step explanation:
Three raise to third power can be written as 
. In this three is the base which is raised to third power.
Next we need to subtract 6 from Three raise to third power(i.e from 27)
which can be written mathematically as
Hence 6 less than three raised to the third power is 21 as explained above.
Both of your answers are correct. In the first equation, if you were to substitute 3 for x, because you have to do exponents first, you have 3^2, which is 9, and 9*6 =54. If you were to substitute -3 for x again you would have to do the exponents first which would be -3^2 which is 9, and 9*6 = 54.
For the second question, if I substitute 0.75 for t, I get -9 + 18 + 7. This is equal to 16, and therefore the answer would be D. Hope this helps! :D. Let me know if you have questions about my explanation, and feel free to post more questions.
Answer:
a= (y-4x-6)/X
Step-by-step explanation:
Make ax the subject of the formulae
-ax=4x+6-y
Multiply both sides by minus (-)
ax= y-4x-6
Divide both sides by x
a= (y-4x-6)/x
