Answer:
4(x-9)² - 17
Step-by-step explanation:
if moving left or right, the a value for (x-a) + b changes, and if it move up or down, the b value for (x-a) + b changes
Answer:
1.45934 × 10^5
Step-by-step explanation:
Answer:3/20
Step-by-step explanation:
Fraction of total area mowed = (3/5) + (1/4) = 17/20
Therefore fraction of total area left = 1 - (17/20) = (20/20) - (17/20) = 3/20
Answer:
(a) (4, 5)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . where m is the slope and (h, k) is the point
Comparing this to
y -5 = 1/2(x -4)
we see that k=5, m=1/2, h=4. Then the point is ...
(h, k) = (4, 5)
Answer:
Step-by-step explanation:
The parametric equations of a circle is
and
The radius of the unit circle is 1 unit.
This implies that any point on the unit circle is represented by:
and
where is the angle in standard position,
From the question, the given angle in standard position is .
This angle intersects the unit circle at
But
We substitute and
This implies that:
