Answer:
Step-by-step explanation:
A graph shows the only real zero to be at x = 3.
Factoring that out gives the quadratic whose vertex form is ...
y = (x -10)² +1
The roots of this quadratic are the complex numbers x = 10 ± i.
_____
For y = (x -10)² +1, the zeros are ...
(x -10)² +1 = 0
(x -10)² = -1 . . . . . . . . . . subtract 1
x -10 = ±√(-1) = ±i . . . . .take the square root
x = 10 ± i . . . . . . . . . . . . add 10

Answer:
<u>B. Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?</u>
<u>Step-by-step explanation:</u>
Remember we are told there's already a question <em>whether pediatricians should recommend</em> <em>early exposure or avoidance.</em> Thus, the research question should answer these two i<em>ssues</em> (<em>early exposure or avoidance)</em>.
Hence, the question we are asking is: Does early exposure to peanuts in small amounts or complete avoidance of peanuts better reduce peanut allergy in children with a known allergy to peanuts?
Simple pythagorus theorem with the equation a^2=b^2+c^2
To find AC, (2^2)+(3^2)=4+9=13
AC=the square root of 13
To find out which snake is the longest, we need to convert all the measurements into either fractions or decimals. In this case, it's probably easier to compare them all as fractions. But, before doing that, since there are two fractions and two decimals, we can compare the fractions and decimals first, and then compare the two largest numbers.
0.08 is obviously less than 0.4, because when comparing the tenths place, only 0.4 has a tenth, meaning it is greater.
1/5 is greater greater than 1/6 because it is a greater unit fraction.
Now, we have to compare 1/5 and 0.4. The easiest way to compare these two is to probably turn them both into <em>decimals</em>. 0.4 is already a decimal, so now we only have to turn 1/5 into a decimal. To make 1/5 a decimal, we just have to preform the division operation, and that gives us that 1/5 as a decimal is 0.2. Since 2<4, that means that the snake that is 0.4 meters is the largest snake.
