You are told that the angle the shape makes is 90 hence its a quarter of the circle so you just find the area of the full circle and divide by 4
(6^2*pi)/4
36pi/4
9pi which is around 27 2 Sig fig
Answer:
The roots of the given equation is x=4,3i,-3i
Step-by-step explanation:
The given cubic equation is
To find the roots we have to equate the equation to zero
ie,
It can be done by using Synthetic division method
Therfore [tex](x-1) is not a factor or root
now put x=-1
Therfore [tex](x-1) is not a factor or root
similarly let x=2,-2,3,-3 all not equal to zero so the are not roots.
let x-4 is a factor of given equation
then it satifies the equation ie (x-4) is a root
And it may be written as
[tex](x-4)(x^2+9)
Answer:
15 customers
Step-by-step explanation:
Given data
Total Number of customers= 25
60% of 25 customers made an additional purchase
Hence the number of customers that made additional purchase is
=60/100*25
=0.6*25
=15customer
Hence 15 customers made additional purchase
Answer: 2/8
Step-by-step explanation:
The probability that the marbles are white or grey is 2/8 because since there is 2 marbles and the total is 8 so you have a probability of 25% to get white or gray
1 mile = 1.6km.
so
100 miles x 1.6km = 160.
The number of km between two cities is 160km.
