Answer:
a. 10
Step-by-step explanation:
x is the radius and any line drawn from centre of the circle to the ends of circle is radius.
using pythagoras theorem:
base^2+height^2= Hypotenuse^2 (over here hypotenuse is radius)
6^2+8^2=x^2
36+64=x^2
100=x^2
x= root of(100)
x=10
The answer is the last on 12
Answer:
A) The graph passes through the point (0, 3), and for each increase of 1 in the x-values, the y-values increase by 1.8
Step-by-step explanation:
We are given the function, .
First, we will substitute x= 0 in the function.
So, we get,
implies i.e. f(0)= 3
Thus, the graph of the function passes through the point (0,3).
Also, we get the table of the values as,
x Difference in f(x) values
1 9.72-5.4 = 4.32
2 17.496 -9.72= 7.776
3 1.4928-17.496=13.997
4
As, we have,
The factor of increase in the y-values = = = 1.8
Thus, we get, the correct option is,
A)The graph passes through the point (0, 3), and for each increase of 1 in the x-values, the y-values increase by 1.8
Answer: think were a week late
Step-by-step explanation:
Midpoint (m) = (x₁ + x₂)/2 , (y₁ + y₂)/2
= (3 - 11)/2, (-5 + 1)/2
= -8/2 , -4/2
= -4 , -2
distance (d) = √[(x₁ - x₂)² + (y₁ - y₂)²
=√ [(-4 - (-2))² + (-2 - 4)²
= √[(-2)² + (-6)²]
= √[4 + 36]
= √40
= 2√10
