Answer:
The answer to your question is letter B or C they have the same response.
Step-by-step explanation:
From the graph we get the center and the radius
- The center is the point shown in the graph and its coordinates are (1, -4).
- The length of the radius is 3 units, from the center we count horizontally the number of squares (3)
Substitution
(x - 1)² + (y + 4)² = 3²
or (x - 1)² + (y + 4)² = 9
Answer:
80 hours is needed
Step-by-step explanation:
answer is d
24/r= 36/27
Cross multiply:
36*r= 24*27
⇒ r= 24*27/36= 18
r=18~
w/0.16 = 6.25
⇒ w= 6.25*0.16
⇒ w= 1
w=1~
Answer:
Step-by-step explanation:
2x2−3x−4=0
For this equation: a=2, b=-3, c=-4
2x2+−3x+−4=0
Step 1: Use quadratic formula with a=2, b=-3, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−3)±√(−3)2−4(2)(−4)
2(2)
x=
3±√41
4
It’s 4, hope this helps :)
