Answer:
I really hope it will help you....
Step-by-step explanation:
Answer1-we can see that in last two hours the line is downwards so we can easily proof or see that at 11th and 12th are the temperature is lowest.
Answer2-in second one we can see that in hour 1,2,3,4 the temperature has kept on increasing.
Answer 3- between three or four temperature of increasing.
We need to make a scale between blueprint and actual size. The trick in this question is to understand that the scale for the areas and the scale for the lengths are different.
Scale for area is given in the question as
1 unit on blueprint = 900 units in actual.
As the dining room is given to be rectangular we can find the scale for lengths by taking square root of scale for area.
√1 unit on blueprint = √900 units in actual
Therefore, scale for length= 1:30
Thus, by using the scale we can calculate actual length corresponding to 4 inches on blueprint by multiplying 4 with scale
4 inches×1/30=120inches
Answer = 120 inches
You use the quadratic formula:
2x {}^{2} - 3x = 5
2x {}^{2} - 3x - 5 = 0
x = \frac{3 + - \sqrt{9 -4(2)( - 5)}}{2 \times 2}
x = \frac{3 + - \sqrt{49} }{4}
x = \frac{3 + 7}{4} \: and \: x = \frac{3 - 7}{4}
x = \frac{5}{2} \: and \: x = - 1
Step-by-step explanation:
This is in the form of
in this case, x is 1 and y is 7. So ourbpoint would be (1,7.)
