X^2+8x+6+2/x+4 am i right ??
Answer:
The graph move up 5.
Step-by-step explanation:
When we add a constant to the end of a parabola, it shifts the graph up and down. Since the constant here is positive, the graph moves up by that number (5)
There are mainly six trigonometric functions for right angle triangle which are
- sinФ
- cosФ
- tanФ
- cosecФ
- secФ
- cotФ
All of these can be expressed in the form of sinФ and cosФ as following:
- sinФ = sinФ
- cosФ = cosФ
- tanФ = sinФ/cosФ
- cosecФ = 1/sinФ
- secФ = 1/cosФ
- cotФ = cosФ/sinФ
This angle Ф is shown in the attached drawing in a right angle triangle drawn within a circle which is the given angle. Right angle is mentioned as "90".
Answer:
Step-by-step explanation:
Equations
x + y = 29
x^2 + y^2 = 425
Solution
y = 29 - x
x^2 + (29 - x)^2 = 425
x^2 + (841 - 58x + x^2 ) = 425
x^2 - 58x + x^2 + 841 - 425 = 0
2x^2 - 58x +416 = 0
a = 2
b = - 58
c = 416
You get two answers that look valid
2x^2 - 58x + 416 = 0
x^2 - 29x + 208 = 0 This factors
(x - 16)(x - 13) = 0
x = 16
y = 13
Now check it
16^2 + 13^2 = ? 425
256 + 169 = 425
Answer:
0.726 < p < 0.874
Step-by-step explanation:
p = 64/83 = about 0.8
confidence interval = p +- z 
= 0.8 +- (1.64 x 0.04472)
= 0.8 +- 0.073343
= (0.726656 and 0.873343)
0.726 < p < 0.874
