Answer:
f(1) = 7
f(2) = 18
f(3) = 31
f(4) = 46
f(5) = 63
f(6) = 82
f(7) = 103
f(8) = 126
f(9) = 151
f(10) = 178
Step-by-step explanation:
f(1) = (-1)^2+8(1)-2 = 7
Continue plugging in values...
The distance formula is: d = sqrt( (x2 - x1)2 + (y2 - y1)2 )
For this problem, let (-5, -4) be the "first" point, so x1 = -5 and y2 = -4
and let (-6, 4) be the "second" point, so x2 = -6 and y2 = 4.
Then: d = sqrt( (-6 - -5)2 + (4 - -4)2 ) = sqrt( (-1)2 + (8)2 ) = sqrt( 1 + 64 ) = sqrt( 65)
The distance formula is just the Pythagorean Theorem applied to an x-y graph.
You would get the same final answer if you let (-5, -4) be the second point and (-6, 4) be the first point.
Answer:
R=30.81≈31
Step-by-step explanation:
34 is the original number.
This is because 34 times 2 is 68 and 68 plus 3 is 71.
Answer:
She needs 3/4 or 0.75 cups of sugar.
Step-by-step explanation:
1/2 = 2/4
2/4 + 1/4 = <em>3/4</em>
<em></em>
Then to get it as a fraction, you divide 3 by 4 and you get 0.75. Hope this helps!!
