Hey You!
20 / 4 = 5
5 × 16 = 80
The Suarez family would have paid $80.00 for 16 tickets.
Answer:
the 1st digit is in the 100s n its 1
step-by-step explanation:
3,589÷18 = 199.389
so the first digit of the quotient is in the 100s n its 1
(i think)
Step-by-step explanation:
Answer: 6.67 feet (check to see if you made a typo)
Step-by-step explanation:
if the scale factor is ten than we multiply 8 by 10
8 * 10 = 80
important to remember this is 80 INCHES not 80 FEET
to convert 80 inches into feet, we divide by 12 because there are 12 inches in a foot
80/12 = 6.67 feet
check to make sure that the first option is actually 6.67 inches because it would make more sense for it to be in feet
The <em>trigonometric</em> function that represents the curve seen in the picture is f(x) = 4.5 · sin (π · x / 2 - π) - 6.5.
<h3>How to derive a sinusoidal expression</h3>
In this problem we need to find a <em>sinusoidal</em> expression that models the curve seen in the picture. The most typical <em>sinusoidal</em> model is described below:
f(x) = a · sin (b · x + c) + d (1)
Where:
- a - Amplitude
- b - Angular frequency
- c - Angular phase
- d - Vertical midpoint
Now we proceed to find the value of each variable:
Amplitude
a = - 2 - (-6.5)
a = 4.5
Angular frequency
b = 2π / T, where T is the period.
0.25 · T = 4 - 3
T = 4
b = 2π / 4
b = π / 2
Midpoint
d = - 6.5
Angular phase
- 2 = 4.5 · sin (π · 4/2 + c) - 6.5
4.5 = 4.5 · sin (π · 4/2 + c)
1 = sin (2π + c)
π = 2π + c
c = - π
The <em>trigonometric</em> function that represents the curve seen in the picture is f(x) = 4.5 · sin (π · x / 2 - π) - 6.5.
