Answer:
y=5x or y=5x+0
Step-by-step explanation:
there is a slope of 5 and it has no setoff
X + y = 250
y + 40 = x
x + y = 250
y = x - 40
x + y = 250
- x + y = - 40
2y = 210
y = 105

The formula for a circle with center (h,k) and radius (r) is as follows:
(x – h)² + (y – k)² = r²
If the diameter of the circle is 10, we know that the radius of the circle must be equal to 5. Insert any known equations into the formula above:
(x – (-3))² + (y – 2)² = 5²
Simplify both sides of the equation:
(x + 3)² + (y – 2)² = 25
This is the equation of a circle with the given measurements.
I hope this helps!
Answer:
x = -10 ° + π/6 + (2 π n_1)/3 for n_1 element Z
or x = 30 ° + π/2 + 2 π n_2 for n_2 element Z
Step-by-step explanation:
Solve for x:
sin(2 x) = cos(x + 30 °)
Rewrite the right hand side using cos(θ) = sin(θ + π/2):
sin(2 x) = sin(30 ° + π/2 + x)
Take the inverse sine of both sides:
2 x = -30 ° + π/2 - x + 2 π n_1 for n_1 element Z
or 2 x = 30 ° + π/2 + x + 2 π n_2 for n_2 element Z
Add x to both sides:
3 x = -30 ° + π/2 + 2 π n_1 for n_1 element Z
or 2 x = 30 ° + π/2 + x + 2 π n_2 for n_2 element Z
Divide both sides by 3:
x = -10 ° + π/6 + (2 π n_1)/3 for n_1 element Z
or 2 x = 30 ° + π/2 + x + 2 π n_2 for n_2 element Z
Subtract x from both sides:
Answer: x = -10 ° + π/6 + (2 π n_1)/3 for n_1 element Z
or x = 30 ° + π/2 + 2 π n_2 for n_2 element Z
Answer:
it's a bit blurry but if I aint wrong it's the 2nd one that say 2/5
