Answer:
y = 6 sin(2x+π/2) +4
Step-by-step explanation:
Given:
-sinusoidal function
-maximum point at (0,10)
-intersects its midline at (π/4,4)
Build the function:
y = sin x , we start with this because is a sinusoidal function
y = sin (x+ π/2), to move the maximum on the y-axis where x= 0
y = sin (2x +π/2), to move the midline from π/2 to a π/4 we need
y = 4+ sin(2x+π/2) , to move the midline from (π/4, 0) to a (π/4, 4)
y = 4+ 6 sin(2x+π/2), to move the max at (0,10), -because the midline is at 4 and the function max at 10 we need 10-4 = 6
Hi there! :)
Answer:
x = -7.
Step-by-step explanation:
Starting with:
3(2x + 2) = 3x - 15
Begin by distributing '3' with the terms inside of the parenthesis:
3(2x) + 3(2) = 3x - 15
Simplify:
6x + 6 = 3x - 15
Isolate the variable by subtracting '3x' from both sides:
6x - 3x + 6 = 3x - 3x - 15
3x + 6 = -15
Subtract 6 from both sides:
3x + 6 - 6 = -15 - 6
3x = -21
Divide both sides by 3:
3x/3 = -21/3
x = -7.

</span><span>time = distance/speed
</span>Keep distance and speed in cm and cm/sec
Meters x 100 = cm time
<span>= 50 m X 100/ 1 = 5000 secs </span>
<span>= 5000/60 mins = 83 1/3 mins </span>
<span>1/3min = 20 sec.
</span>So 83 1/3 mins
<span>= 1 Hr 23 Min and 20 Secs</span>
Answer:
y = 2x - 3
Step-by-step explanation:
Slope intercept form : y = mx + b
6x - 3y = 9
-3y = -6x + 9
y = 2x - 3
Option 4 will be the answer:)
