n can be all the way upto 7 as 8 x4 = 32 which is higher than 30. The lowest possible diggit is 1.
n = 1, 2, 3, 4, 5, 6, 7
1 + 2 + 3 + 4 + 5 + 6 + 7 = 28

Multiply both sides by 20
Answer: see graph
<u>Step-by-step explanation:</u>
Look at the Unit Circle to see the coordinates of the quadrangles.
Build a sine table for one period (0° - 360°).
<u> x </u> <u> y = sin(x) </u> <u> y² = (sin(x))² </u> <u> (x, y²) </u>
0° sin(0°) = 0 (0)² = 0 (0°, 0)
90° sin(90°) = 1 (1)² = 1 (90°, 1)
180° sin(180°) = 0 (0)² = 0 (180°, 0)
270° sin(270°) = -1 (-1)² = 1 (270°, 1)
360° sin(360°) = 0 (0)² = 0 (360°, 0)
Now plot the (x, y²) coordinates on your graph.
Answer:
No solution
Step-by-step explanation:
y=x-1 and y-x=-9
1st make sure both equations are in slope intercept form
since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so
y-x=-9
+× +×
y=×-9
now you have y=x-1 and y=x-9
substitute the y with the other equation
x-1=x-9
subtract x from both sides since you can't have the variable on both sides
now you've got -1 = -9
and since that equation isn't true, it has no solution.
