Answer:
C = 96.71 inches
A = 745.06 in ^2
Step-by-step explanation:
d = 30.8
The radius will be 1/2 d= 1/2 (30.8) = 15.4
The circumference = pi *d
= pi * 30.8
=96.761
The area = pi * r^2
= pi * (15.4)^2
= 745.06011
Polynomial that represents a difference in cubes.
x³ - 64 = 0
x³ = 64
∛x³ = ∛64
x = 4
Correct Steps for factoring the polynomial 5x³ - 40
5(x³ - 8)
5((x)³ - (2)³)
5(x - 2)(x² + 2x + 4)
To check:
5(x - 2)(x² + 2x + 4)
(5x - 10) (x² + 2x + 4)
5x(x² + 2x + 4) - 10(x² + 2x + 4)
5x³ + 10x² + 20x - 10x² - 20x - 40
5x³ + 10x² - 10x² + 20x - 20x - 40
5x³ - 40
To make this easier the answer is, "y = 2x + 5"
Answer: 64%
Step-by-step explanation:
Given the following :
Current price of stock = $50
Probability of increase per day = 40% = 0.4
Probability of decrease = 60% = 0.6
Value of increase = $11
Value of decrease = $13
Probability that stock is greater than $30 in two days :
For stock to be greater than $30 in two days ;
It either increases in both days or increases in a day and falls the other
Hence, probability that stock is greater than $30
P(increase and increase) OR P(increase and decrease) OR P(decrease and increase)
(0.4 × 0.4) + (0.4 × 0.6) + (0.6 × 0.4)
0.16 + 0.24 + 0.24 = 0.64
0.64 × 100 = 64%
