Answer:
4
Step-by-step explanation:
In a equilateral triangle, all angles are 60 degree, so 10x+20=60
10x=40
x=4
Answer: a) -13/16
Step-by-step explanation: Start by setting equations equal and rearrange X^3 - x^2 + 1 = 0. Visual inspection of graph shows x between -1 and -1/2. Start with x = 3/4 plug in and calculate: just a little too small. Try going halfway towards -1: x =-7/8 Plug in and the answer is very far from 0. Go halfway back towards -3/4: -13/16 and the equality is very close.
Answer:
Option OD - 9
Step-by-step explanation:
Given : On the cardiac ward of a local hospital, there are 7 nursing assistants. The seven assistants have 7, 8, 5, 9, 10, 10, and 14 patients, respectively, that they assist.
To find : What is the average number of patients per nursing assistant?
Solution :
The average number of patients per nursing assistant is given by the division of sum of number of patients by total number of nursing.
So, 



Therefore, The average number of patients per nursing assistant is 9.
So, Option OD is correct.
Answer:

Step-by-step explanation:
The function
has the following characteristics:
- Factors:

- Zeros/roots: x=0, x=-1, amd x=4
- Positive leading coefficient
- Graph starts down and curves up through -1 on the x-axis and back down to cross through 0. It curves back up again through 4 and finished off heading into positive infinity.
- Its graph is the shape of a sideways S.
- It has a relative maximum at 1.128 and relative minimum value of -13.128
