The first question 10 and the next one is 40 the next one is 30
Answer:
- 7
- see below
- 5
- the rule is not one-to-one
Step-by-step explanation:
Applying the squaring rule to each of the elements of the domain, we get ...
![\begin{array}{cc}\text{Domain}&\text{Range}\\1&1\\-3&9\\-\frac{1}{2}&\frac{1}{4}\\3&9\\2&4\\\frac{1}{4}&\frac{1}{16}\\0.5&\frac{1}{4}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%5Ctext%7BDomain%7D%26%5Ctext%7BRange%7D%5C%5C1%261%5C%5C-3%269%5C%5C-%5Cfrac%7B1%7D%7B2%7D%26%5Cfrac%7B1%7D%7B4%7D%5C%5C3%269%5C%5C2%264%5C%5C%5Cfrac%7B1%7D%7B4%7D%26%5Cfrac%7B1%7D%7B16%7D%5C%5C0.5%26%5Cfrac%7B1%7D%7B4%7D%5Cend%7Barray%7D)

1. There are 7 different numbers in the Domain list.
2. See above
3. There are 5 different numbers in the Range list.
4. The rule "square me" is not "one-to-one" Two different values in the domain can result in the same value in the range. -3 and 3 both result in 9. -1/2 and 0.5 both result in 1/4.
Answer:
width of a river = 45m
Step-by-step explanation:
ration and proportion
let x = width of a river
x 20.9 m
------ = --------
56 m 26 m
x = (20.9 * 56) / 26
x = 45 m
therefore the width of a river is 45 m
<span>5.5*10^5 = 550,000 tons
</span><span>$23,000 per ton
</span>
23,000 x 550,000 = <span>$12,650,000,000 (total value)
</span>Now to convert to scientific notation.
<span>1.265 x 10^10
</span>
Hope that was useful :)
Plug in the 1/2 where the a’s are answer is -3
