(x - 5) represents the total charge before applying sales tax.
Answer:
Your answer of option b is right.
Step-by-step explanation:
Given that a sinesoidal function has maximum 12 and minimum -6
Hence centre line would be average of these two.
Centre line is
i.e. f(x) = a sin (bx+c)+3
Since amplitude = 12-3 =9 we have a = 9
i.e. f(x) = 9 sin (bx+c)+3
Frequency is given as 3, period = 1/3
This gives b = 6pi
f(0) = y intercept =
9sin(c)+3 =3
This gives c=0
Hence correct equation is
Answer:
. In other words, these two angles are both right angles, and this parallelogram would be a rectangle.
Step-by-step explanation:
Two angles that congruent have the same size.
At the same time, those two adjacent angles of this parallelogram would be a pair of consecutive interior angles. Because the two sides of a parallelogram are parallel to one another, the sum of these two consecutive interior angles would be - they are supplementary to one another.
Let the two angles be and .
because the two angles are congruent.
because these two angles are adjacent angles of a parallelogram.
Hence, .
Answer: 2/3
First, you have to add all of the counters to get the denominator (bottom number). 5+3+1=9. The number of blue counters is 5+1 (red+yellow)=6. Then use the fraction 6/9. Then, simplify to get 2/3.
Step-by-step explanation:
Amount of green clay at the start = 57g + 31g = 88g.
Amouny of green clay used = 88g - 18g = 70g.
Hence 70g of green clay was used during the week.
