Answer:
[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]
Step-by-step explanation:
The standard form for a sinusoidal function is given by:
y = Asin[B(x - C)] + D
Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation
Given:
A = 2, D = -5 (down), C = -3 (left).
8 = 2π/B; B = π/4
Therefore:
[tex]y=2sin[\frac{\pi}{4}(x+3) ]-5[/tex]

How many runners ran at least 3 miles?
Enter your answer in the box.
{ } runners
Answer:
7 runners
Step-by-step explanation:
In order to figure this question out, you need to count them up. Count up all the runners that are plotted from 3 miles on. Anything before that is under 3 miles, so it doesn't count.
After counting them up, you will find that there are 7 runners marked who ran 3 miles or more. So your answer is 7 runners.
I hope this helps! Please let me know if you need any more help. Have a great day!

Fannie has a credit card that using the average daily balance method. For the first 16 days of one of her billing Cycles, her balance was $1,050, and for the last 14 days of the billing cycle, her balance was $1,280. If a credit cards APR is 19%, which of these Expressions could be used to calculate the amount Fannie was charged in interest for the billing cycle?
A. (0.19/365 x 31)(16 x $1050+14 x $1280/31)
B. (0.19/365 x 30)(16 x $1050+14 x $1280/30)
C. (0.19/365 x 30)(14 x $1050+16 x $1280/30)
D. (0.19/365 x 31)(14 x $1050+16 x $1280/31)
Answer: B. (0.19/365 x 30)(16 x $1050+14 x $1280/30)

i need help with the volume, tsa and x please
Answer:
Volume = 42 units^2
x = 5 units
Total Surface Area = 96 units
Step-by-step explanation:
Volume
V = bh, where b = 1/2 * 3 * 4 and h = 7,
= 6 * 7 = 42 units^2
x
You can solve for this variable by using the pythagorean theorem;
a^2 + b^2 = c^2, where a = 3 and b = 4,
9 + 16 = x^2
= 25 = x^2
= x = 5 units
Total Surface Area
You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:
7 * (3 + 4 + 5) + 2(1/2*3*4)
= 7*12 + 12
= 96 units
PLEASE I NEED HELP ASAP
I need helppp plzzzzz
Answer:
b^8
Step-by-step explanation:
Answer:
b^8, with m = 8
Step-by-step explanation:
Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)
Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.
From this rule, we know that (b^10)/(b^2) = b^(10-2)
b^(10-2) can be written b^8

Which of the following points does not lie on the line y = -2x +5?
A. (4-3)
B. (-2,9)
с. (3,1)
D. (-1,7)
E. (2, 1)
Answer:
C (3, 1 )
Step-by-step explanation:
To determine if a point lies on the line, substitute the x- coordinate of the point into the equation and if the value obtained equals the y- coordinate of the point then it lies on the line, otherwise not on line.
A (4 , - 3)
y = - 2(4) + 5 = - 8 + 5 = - 3 ← lies on line
B (- 2, 9 )
y = - 2(- 2) + 5 = 4 + 5 = 9 ← lies on line
C (3, 1 )
y = - 2(3) + 5 = - 6 + 5 = - 1 ≠ 1 ← not on line
D (- 1, 7 )
y = - 2(- 1) + 5 = 2 + 5 = 7 ← lies on line
E (2, 1 ) = - 2(2) + 5 = - 4 + 5 = 1 ← lies on line
Thus (3, 1 ) does not lie on the line → C
