Step-by-step explanation:
It is given that :
Initial temperature,
Final temperature,
Time taken :
Change in temperature per hour:
Putting the values of temperatures and time:
The error done by Wen was during calculating the values of fraction.
So, the correct answer is : instead of
The answer to that question is 250.
Answer:
power index
Step-by-step explanation:
Prime factor index form is expression of a number as product of its prime number. Here the prime factor is listed only once. It is necessary to insert the required power index to solve for the HCF
<span>Answer: two options apply: A and D.
</span>
<span /><span /><span>A. As the y-intercept increases, the graph of the line shifts up.
D. As the y-intercept decreases, the graph of the line shifts down.
</span><span />
<span>Justification:
</span><span>1) Take the slope-intercept equation of the line: y = f(x) = mx + b</span>
<span /><span>
</span><span>2) The y-intercept is b
</span>
<span /><span /><span>
3) When b is increased, f(x) will increases too, that is f(x) will be higher or its graph will be shifted up, which is what the option A. states.
</span><span />
<span>4) When b is decreased, f(x) will decreases too, that is f(x) will be lower or its graph will be shifted dOwn, which is what the option D states.
</span><span />
<span>5) Regarding the options B and E, which deal with motions in the horizontal direction (left or righT), nothing can be said, as the effect of a change in the y -intercept on the horizontal direction will depend on the slope.
</span><span />
<span>6) Regarding the option C, a change in the y-intercept does not change the slope (the steep of the line).
</span><span />
Answer:
it's the 2nd one
Step-by-step explanation:
d = 3 + at^2
-3 | -3
d - 3 = at^2
d - 3/a = t^2
√d - 3/a = √t^2
t = √d - 3/a
