A=1/2 * d1 * d2
a=1/2 * 2.7 * 3.2= 4.32mm
Answer:
-11
Step-by-step explanation:
Plug in 0 for x and 3/5 for y into the expression
-4(0) + 5(3/5) - 14
Multiply the numbers inside the parentheses
0 + 3 - 14
3 - 14 = -11, which is your answer
The property here is the Commutative Property of Addition.
If you divide by a decimal, you are breaking apart 1 into multiple pieces and so you are trying to find how many of that size piece will fit into 5. For example if you divide by .5 (point five), there are 2 point fives in 1 so there are 10 point fives in 5. The quotient is larger.
I hope you got that...
Answer:33/9
Step-by-step explanation:
Log10(x+3)-Log10(x-3)=1
Log10((x+3)/(x-3))=1
(x+3)/(x-3)=10^1
(x+3)/(x-3)=10
Cross multiply
x+3=10(x-3)
Open brackets
x+3=10x-30
Collect like terms
10x-x=30+3
9x=33
Divide both sides by 9
9x/9=33/9
x=33/9
