Answer:
I do not agree, because x=4 is an extraneous
Step-by-step explanation:
First, to solve the equation, you subtract 3 from both sides, then square both sides, subtract one from both sides, and finally divide by 2 on both sides. This indeed gets us x=4, but we also need to check if it's an extraneous solution. To do that we simply plug in x=4 into the original equation. sqrt( 2(4) + 1 ) + 3 = 0. When we do this, we end up with ±3 + 3 = 0. I do not agree, because we don't know if the sqrt(9) is -3 or 3.
Answer:
Table I fill-in: 1.404
Table II fill-in: 1.661 (instead of the 2 that's there)
Step-by-step explanation:
The functions shown in Table I and II are inverses of each other. This means that the x's for Table I are the y's in Table II. And the y's in Table I are the x's in Table II.
So look at Table II, there is a coordinate pair
(7, 1.404). Switch the x and y and you get (1.404,7) That's your answer to fill in on Table I.
It is 19 degrees (19 times 2 equals 38. 38+10=48
find the area of the base which is 8*8=64 in^2
then the triangles one is 2*[(6*4)/2)]= 24 in^2 and theres 4 of them so times 4
24*4=96 in^2
then add and u get 160 in^2
