Just substitute 4 for x in the given equation:
h(4) = 3^4 - 7 = 81 - 7 = 74 (answer)
3.14 - 3a Radians
Because
180o = 3.14 radian
N*(21/100)=(700/100)
n=(700/100)/(21/100)
n=(700/100)*(100/21)
n=700/21
n=33+1/3
So <em><u>thirty three</u></em> $0.21 pencils can be purchased for $7.00.
Answer:12 cups of sugar
Step-by-step explanation:
There is 6 batches each batch has two cups you would do 6x2 for 12 cups.
If the matrix is of 2 by 2 then we can find the determinant of the matrix.

Then (ad - bc ) gives you the determinant of the matrix.
For example,

= (2)(-2) - (1)(4)
= - 4 - 4
= -8
