The end result would be ( 11/5 , -15/5)
Answer:
a. Amplitude: 19.65446
b. Vertical Shift: 58.00713
c. Period: 2/0.22797 = 27.56146
d. 19.65446 * sin(0.22797x + 1.79552) + 58.00713
e. Model's Temperature at 10 A.M.: f(-7) = 61.91
This value is 9.91 degrees higher than the actual value.

Answer:
Step-by-step explanation:
1) 5 times the length x of the table = 5*x = 5x
the sum of 8 inches = 5x + 5
5x + 8
2) Half the weight of w of a bag of rice =
6 pounds less than =
3) The product of 2 coins and c coins = 2*c = 2c
2c
Answer:
y=-4x+2
Step-by-step explanation:
Hi there!
We want to find out which equation represents a line with a slope of -4 and a y intercept of (0,2)
The most common way to write the equation of the line is in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
We have everything we need to plug into the equation, let's just label the values to avoid confusion
m=-4
b=2 (when you substitute the y intercept as b, b is the value of y in the point)
Now substitute into the equation
y=-4x+2
Hope this helps!
Answer:
π/2, 2π/3, 3π/2, 4π/3.
Step-by-step explanation:
8cos^2x+4cosx=0
4cosx(2cosx + 1) = 0
so cosx = 0, -1/2.
Therfore
When cos x = 0:
x = π/2, 3π/2
When cos x = -1/2:
x = 2π/3, 4π/3.
