Answer: 24x - 2
Step-by-step explanation: 7x -2 + 10x + x + 6x
24x -2
Answer:1/2
Step-by-step explanation:
"Or" means add, so you add the two events together.
Answer:
1.462 × 10^20
Step-by-step explanation:
Multiplication proceeds in the usual way. The rules of exponents apply. A final exponent adjustment is needed to put the number in scientific notation form. (Your calculator can do all of this for you.)
(4.3×10^12)(3.4×10^7) = (4.3×3.4)×(10^12×10^7) = 14.62×10^(12+7)
= 14.62×10^19
= (1.462×10)×10^19 = 1.462×10^(1+19)
= 1.462×10^20
_____
The rule of exponents used is ...
(a^b)(a^c) = a^(b+c)
_____
I find it works well to estimate whether the product of the mantissas will be more than 10, then make adjustments to exponents before the multiplication:
(4.3×10^12)(3.4×10^7) = (4.3×10^12)(0.34×10^8) = 1.462×10^(12+8)
= 1.462×10^20
Answer:
9/2 or 4 1/2
Step-by-step explanation:
- 3/4 ÷ 1/6 = 3/4 × 6
- 3/4 × 6 = 18/4
- 18/4 = 9/2
- 9/2 = 4 1/2
Therefore, the answer is 9/2 or 4 1/2.
Answer:
The solution is 
Step-by-step explanation:
From the question we are told that
The function is
, -1 < x < 1 a = 4
Here we are told find 
Let equate

So
![4 + x^2 + tan[\frac{\pi x }{2} ] = 4](https://tex.z-dn.net/?f=4%20%2B%20%20x%5E2%20%20%2B%20tan%5B%5Cfrac%7B%5Cpi%20x%20%7D%7B2%7D%20%5D%20%3D%20%204)
![x^2 + tan[\frac{\pi x }{2} ] = 0](https://tex.z-dn.net/?f=x%5E2%20%20%2B%20tan%5B%5Cfrac%7B%5Cpi%20x%20%7D%7B2%7D%20%5D%20%20%3D%20%200)
For the equation above to be valid x must be equal to 0
Now when x = 0
![f(0) = 4+0^2 + tan [\frac{ \pi * 0}{2} ]](https://tex.z-dn.net/?f=f%280%29%20%3D%204%2B0%5E2%20%2B%20tan%20%5B%5Cfrac%7B%20%5Cpi%20%2A%200%7D%7B2%7D%20%5D)

Differentiating f(x)

Now
since
We have
