Answer:
Step-by-step explanation:
We have, 120% × x = 36
or,
120
100
× x = 36
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 36 ×
100
120
x = 30
6.7 would be correct hundreth is the second place behind the decimal
Answer:
arithmetic
Step-by-step explanation:
The points fall on a straight line. They won't do that for a geometric sequence.
___
Normally the terms of either sort of sequence are numbered with counting numbers: 1, 2, 3, .... Your x-values are negative, so are obviously not term numbers of a sequence. The differences of x-values are 1, and the differences of y-values are 2.5, so we know the x- and y-values are linearly related. That relationship can be expressed in point-slope form by ...
y = 2.5(x +1) +12.5
which can be simplified to
y = 2.5x +15
__
The arithmetic sequence with first term 17.5 and common difference 2.5 would be described by this same equation.
Square root of (-5-1)^2+(-4-4)^2
Square root of (-6)^2+(-8)^2
Square root of 36+84
Square root of 120
Your calculator should give you the answer to both.
3^3 = 3 * 3 * 3 = 27
∛(125) = ∛(5 * 5 * 5) = Three equal factors under a cube root sign give 1 factor on the left of the cube root sign. The other 2 are discarded.
∛(5 * 5 * 5) = 5∛1 = 5
