Answer:
30 times
Step-by-step explanation:
$400 minus $250=$150
$150 divided by $5=30 so she can go 30 times
Answer:
3
Step-by-step explanation:
Answer:
Vertex: (- 2, -1)
axis of symmetry: x= - 2
Step-by-step explanation:
f(x)=x^2+4x+3
f(x)=(x^2+4x+4)+3-4.......complete the square
f(x)=(x+2)^2-1...................write in vertex form
Answer:
a^2 + b^2 = c^2 (pythagorean theorem)
a^2 + 40^2 = 41^2 (plug in the known values)
a^2 + 1,600 = 1681 (simplify what you can)
a^2 = 81 (subtracted 1600 from both sides)
a= (81 under a radical) (I think this is what your answer will be, based on the problem)
a=9 (what the fully simplified answer is)
Values of x and y will be 12 and 5 respectively.
It's given in the question,
- Three points Q, R and S are collinear.
- Coordinates of Q → (2, 0)
- Coordinates of R → (8, 3)
- Coordinates of S → (x, y)
- QR : RS = 3 : 2
Since, expression for the coordinates of a point (h, k) which divides the segment joining points 
and 
in the ratio of m : n is given by,
h = 
k = 
Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,
Similarly, 
Therefore, values of x and y will be 12 and 5 respectively.
