Answer:
Step-by-step explanation:
In order to find r we have to square both sides of the equation
The *square root* sign cancels out the *squared* sign therefore:
Answer:
5.16
Step-by-step explanation:
Since after x=3, value of y starts decreasing for increasing values of x, let's choose. Also we need to find f(x) for x=3.4
x=3,4,5 and f(x)=7,3,1 to find lagrange polynomial
P(x)= ((x-x2)(x-x3)y1)/((x1-x2)(x1-x3) + ((x-x1)(x-x3)y2)/((x2-x1)(x2-x3) + ((x-x1)(x-x2)y3)/((x3-x1)(x3-x2)
P(x)= ((x-4)(x-5)7)/((3-4)(3-5)) + ((x-3)(x-5)3)/((4-3)(4-5)) + ((x-3)(x-4)1)/((5-3)(5-4))
P(x)= x² -11x+31
P(3.4)= 5.16
Area of a Circle = PI * radius^2
= 3.14 * 1.8^2
= 3.14 * 3.24
= 10.17 meters^2
No 5/8 is bigger because half of 8 is 4 and 5 is greater than 4
Answer:
This is actually a reduction, and the scale factor of this dilation is 0.5.
