Answer:
It is the third option. (the one which has a black point at X=1, Y=1)
Step-by-step explanation:
For simplicity what you should do is, you should satisfy the second condition that is, y=0 if x=1.
Here only the third option is satisfying this condition.
Whenever there is is a white circle or a white point it means that the point does not satisfy the condition and the the function is not defined at that point. And the black point means that the circle is defined at that point and satisfies the condition.
Henceforth, the correct answer is the third option.
Answer:
b = 12
Step-by-step explanation:
y = mx + b
b = 12
24 degrees per second is 360 degrees in 15 seconds (pretty fast for a Ferris wheel!).
a) The distance above the ground can be modeled using a cosine function.
.. h(t) = 7 -6cos(2πt/15)
b) h(t) = 10
.. 10 = 7 -6cos(2πt/15)
.. (10 -7)/-6 = cos(2πt/15)
.. 2πt/15 = π ±π/3 +2kπ
. t = 7.5*((1 ±1/3) +2k) . . . . . . . . seconds; k = any integer
You are 10 meters above the ground at t=5 seconds and every 15 seconds thereafter, as well as at t=10 seconds and every 15 seconds thereafter.
Answer:
$7.7
Step-by-step explanation:
Step one:
given data
total money = $175
He buys 4 shirts for $24 each= 24*4= $96
The shirts are discounted 20%
= 96- 0.2*96= 96-19.2= $76.8
2 pairs of shorts for $18 each= $36
2 pairs of pants for $22.50 each= $45
Total cost = $157.8
tax= 6%
total expenses
= 157.8+ 0.06*157.8
=157.8+9.468
=$167.268
The balance is
= 175-167.268
=$7.7
