Answer:
f(t)=4cos(t), â3Ï/2â¤tâ¤3Ï/2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
From the graph, we can see that the <em>temperature increased initially</em>, then <em>started to decrease</em>. <u>All of these NOT in a constant rate, though</u>.
Roughly, the temperature was increasing from start till around 5.5 hours. Then on the temperature decreased.
So we can eliminate B, C, and D. That leaves us with correct answer as A.
When the bases are diffenrent and the exponents of a and b are the same, we can multiply a and b first:
a n ⋅ b n = (a ⋅ b) n
Example:
32 ⋅ 42 = (3⋅4)2 = 122 = 12⋅12 = 144
When the bases and the exponents are different we have to calculate each exponent and then multiply:
a n ⋅ b m
Example:
32 ⋅ 43 = 9 ⋅ 64 = 576
B) the values will create a line with positive slope when graphed on a scatter plot.
Answer:
Step-by-step explanation:
The slope-intercept form of equation of a linear function:
m - slope
b - y-intercept
We have the slope m = 4/5 and the y-intercept b = -6. Substitute:
