Y2-y1 over x2-x1 or you can go onto the calculator and push list and put in the points and it will give you the answer of 68
Answer:
<em>Answer: C</em>
Step-by-step explanation:
<u>The Cosine Function</u>
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
Thus:
Therefore, the equation of the sinusoid is:
Answer: C
Answer:
z = 96; x = 8.
Step-by-step explanation:
z = 96. This is because the angle measuring z degrees is a vertical angle of the angle measuring 96 degrees, which means that the two angles are congruent.
The angle measuring 5x + 44 degrees forms a straight angle with the 96 degree angle. That means that the measurements of the two angles will add to be 180 degrees.
5x + 44 + 96 = 180
5x + 140 = 180
5x = 40
x = 8

Answer:
jil got 18 chocolates
Step-by-step explanation:
let the ratio constants be x,
so, jil has 3x chocolates
katie has 4x chocolates
and we know total chocolates = 42
then,
=》3x + 4x = 42
=》7x = 42
=》x = 42 ÷ 7
=》x = 6
so, jil got 3x = (3 × 6) = 18 chocolates
katie got 4x = (4 × 6) = 24 chocolates
