Answer:
16
Step-by-step explanation:
Okey dokey my dude, here's the deal. All you have to do to answer this is use order of operations (parentheses exponents multiplication division addition subtraction).
8÷2(<u>2+2</u>)=?
//parenthesis first
8÷2(4)
//Ok here's where people will mess up. They just look at the problem and assume that you should multiply the 2 and (4) first because the 4 is in parenthesis. That's understandable, but wrong. What the equation should really look like is 8÷2·4. So you should do 8÷2 first.
<u>8÷2</u>·4=?
4·4=?
<u>16=16</u>
Answer:
7.415 ≤ x < 7.425
Step-by-step explanation:
The number x was rounded to 2 decimal places to give 7.42.
Since rounded off to 2 decimal places, the error interval for x is half of 0.01 subtracted from and added to 7.42.
Thus;
7.42 ± (0.01/2)
(7.42 - 0.005),(7.42 + 0.005)
7.415, 7.425
Now, 7.425 will not be included in the internal because approximating it doesn't give 7.42.
Thus,the error interval is;
7.415 ≤ x < 7.425
The given function is
![h(x) = \{ (0,1), (2,3), (-4, 1) \}](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5C%7B%20%280%2C1%29%2C%20%282%2C3%29%2C%20%28-4%2C%201%29%20%5C%7D)
The inverse function is
![h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}](https://tex.z-dn.net/?f=h%5E%7B-1%7D%28x%29%20%3D%20%5C%7B%20%281%2C0%29%2C%20%283%2C2%29%2C%20%281%2C-4%29%5C%7D)
To get the inverse, we swap each x and y coordinate.
The rule is ![(x,y) \to (y,x)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%5Cto%20%28y%2Cx%29)
So that's why the point (0,1) becomes (1,0) for instance.
