Answer:
B
Step-by-step explanation:
If a sinusoidal function is given in the form y = B Sin x or y = B Cos x, then,
B is called the amplitude of the function. It will define minimum and maximum.
The minimum & maximum of this form of a cos function is B and -B.
The function given is y = 7 Cos x, so the Maximum is 7 and Minimum is -7
Correct answer is B.
Answer: $3.16.
Step-by-step explanation:
You want to leave a 15% tip on a meal that cost $21.05.
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $21.05 meal cost is.This is always done by multiplying 0.15 by $21.05, or
0.15 x $21.05=$3.16.
So, the amount of tip you are going to leave is $3.16.
Answer: 20
Explanation: triangle=10 , circle= 5 , square= 4 , half square = 2....... 5 x 2 = 10 plus 10 = 20:)
X + 4/9= 3/4
subtract 4/9 from both sides
x= 3/4 - 4/9
change to common denominators
x= 27/36 - 16/36
subtract numerators only
x= 11/36
ANSWER: (A) 11/36
Hope this helps! :)
Cost of two sets: 75.85 x 2 = 151.7
Discount: 151.7 - 141 = 10.70
Discount on each set = 10.70 / 2 = 5.35
Answer = $5.35
