At first you have 1 and then 1 and 1 and you know that 1+1=2 so you have 1, 2, 1, and then you know that 1+2=3 and 2+1=3 so yu have 1,3,3,1 and then you know that 1+3=4 and 3+1=4 so you have 1,4,4,1 and it goes like that until the end.
Answer:
<D = 147 degrees
AB = 14
BC = 12
Step-by-step explanation:
From the given parallelogram;
<A and <D are supplementary, hence;
<A + <D = 180
33 + <D = 180
<D = 180 - 33
<D = 147 degrees
Since AB = CD
Hence AB = 14
Also since BC = AD, BC = 12
<em>This shows that the opposite side of the parallelogram are parallel</em>
Answer:
first and last statement listed
Explanation:
because f(c) is showing time, the start of the reaction will be when the y axis = 0 (because 0 time will have passed)
we can see the value of x/c is 20 when y/f(c) is 0 (20, 0)
indicating that the concentration of the chemical is 20 milligrams/liter at the start of the reaction.
<u>{first statement correct}</u>
<em>[second statement incorrect]</em>
Because the x-value [c] is increasing with the y-value [f(c)], we know that the concentration of the chemical increases as the reaction progresses over time. (time increases, concentration increases)
<u>{last statement correct}</u>
<em>[third statement incorrect]</em>
note that "the concentration of the chemical does not fall below 20 milligrams/liter" does not say anything about when [meaning during the reaction, at the start of, or before are all being considered] the concentration is less than 20 milligrams/liter.
We can see, that <em>before</em> this reaction, the concentration of the chemical <em>does </em>fall below 20 milligrams/liter
<em>[fourth statement incorrect]</em>

Answer:
1) X=12
Step-by-step explanation:
The triangle is congruent by SAS because one side is congruent, one is 90 degree that means other angle is also 90. Which is SAS, if the triangle is congruent then cpctc
