Answer:
Choice C (OS)
Step-by-step explanation:
the radius is half of the diameter which is AB, or any line from point O to the actual circle. And because one option is point O to point S (point on circle) the answer is Choice C (OS)
Answer:
25 units
Step-by-step explanation:
H^2= S1^2 + S2^2
= 15^2 + 20^2
=225 + 400
= 625
= square root of 625
= 25 units
Answer:
See below in bold.
Step-by-step explanation:
A. (x + 7)^2 + (y - 7)^2 = 10.
This is the equation of a circle.
It is NOT a function
One to many correspondence.
B. y = x^2 + 2x - 3
This is a parabola which opens upwards.
It is a function.
For 2 values of x ( except at the vertex) there is one value of y so it is
many to one correspondence.
Answer:
Polynomial: A = x(x+4)
A = 572 ft^2
Step-by-step explanation:
The polynomial is just x, the width, multiplied by x+4, the length.
The area is just A = 22(22+4). This equals 572 ft^2
Answer:
k = (1 , 4)
Step-by-step explanation:
here's your solution
==> k^2 - 5k + 4. [ is expression ]
==> by using middle term split
==> k^2 - 4k - k + 4
==> taking common from each
==> k(k - 4) - 1 (k - 4)
==> (k - 1) , (k - 4).
==> k - 1 = 0
==> k = 1
==> k - 4 = 0
==> k = 4
hence , k = (1 , 4)
hope it helps
