The equation of a circle is:
(x - h)² + (y - k)² = radius²
where (h, k) is the center of the circle.
Your center is (- 2, - 7).
Your radius is √81 = 9
The length of ST is 10 units, the length of S't" is 2 units.
This means the dilated figure was decreased by a factor of 5.
Because it is smaller it would be a scale factor of 1/5 ( 0.2 as a decimal).
Answer:
7.142m/s
Step-by-step explanation:
Velocity=change is distance/change in time
change in distance=400m-0m=400m
change in time=56-0=56seconds
v=400m/56s
v=7.143m/s
Answer:
(x-3)
Step-by-step explanation:
we have
step 1
Simplify the numerator
Complete the square
Equate the equation to zero
Rewrite as perfect squares
Take square root both sides
therefore
substitute in the numerator
The equation given is in slope-intercept form. This is the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -4 and the y-intercept is 2. The answer is A.
