We don't know what equation solver you're supposed to use. Here are the results from one available on the web.
Answer:
2
Step-by-step explanation:
Add up the numbers you are given. (-10) + (-5) + 2 + 6 + 17 = 10. Now divide by the number of values. There are 5 values. 10/5 = 2
Answer:
15/56x^(-4/7) + 32x^3 + 6.
Step-by-step explanation:
Using the rule for algebraic differentiation:
If y = ax^n, dy/dx = anx^(n-1).
So :
If y = 5/8x^3/7 + 8x^4 + 6x - 9
dy/dx = 5/8* 3/7 x^(3/7-1) + 8*4 x^(4-1) + 6x(1-1)
= 15/56x^(-4/7) + 32x^3 + 6.
Let's calculate first, how many such numbers there are, where the same three digits are different form 0.
![\underbrace{1\cdot1\cdot1\cdot1}_{\text{XXX0}}\cdot\underbrace{9}_{\text{X=\{1,2,\ldots,9\}}}\cdot\underbrace{3}_{\text{XXX0,XX0X,X0XX}}=27](https://tex.z-dn.net/?f=%20%5Cunderbrace%7B1%5Ccdot1%5Ccdot1%5Ccdot1%7D_%7B%5Ctext%7BXXX0%7D%7D%5Ccdot%5Cunderbrace%7B9%7D_%7B%5Ctext%7BX%3D%5C%7B1%2C2%2C%5Cldots%2C9%5C%7D%7D%7D%5Ccdot%5Cunderbrace%7B3%7D_%7B%5Ctext%7BXXX0%2CXX0X%2CX0XX%7D%7D%3D27)
Now, the numbers where there are three 0's. There are only 9 of those
![1000,2000,\ldots,9000](https://tex.z-dn.net/?f=%201000%2C2000%2C%5Cldots%2C9000%20)
So, there are
such numbers.
