5 - 6 pm
if the temperature drops 3 degrees per hour. so how many hours would it take to go from 98.6 to 86.3
98.6-86.3=12.3
3 goes into 12 4 times.
10 pm - 4 hours is 6pm.
if you figure in the .3
you come to approximately 5pm
Are you seriously asking that? 4.25 - 2.75. 1.5 is the answer
You could type in -0x+Y=-3 or 0x-Y=3 if you want x to be positive
The line of the graph has a slope of 0 so if you put it in y intercept form it would be
y=0x-3 so if you subtract x from both sides you would get -0x+Y=-3 and that would put the equation into standard form. I’m not 100% sure if it’s correct so I’m hoping it’s correct
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
Answer:
The radius is r=5 units
Step-by-step explanation:
we know that
The equation of the circle in standard form is equal to
where
(h,k) is the center and r is the radius
we have
Convert to standard form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
therefore
The center is the point (6,-3) and the radius is r=5 units
