Mathematics

Answer:

height = 7 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated using the formula

A = \frac{1}{2} h(a + b)

where h is the height and a, b the parallel bases

here a = 6, b = 12 and A = 63, hence

\frac{1}{2} × h × (6 + 12) = 63

\frac{1}{2} h × 18 = 63

9h = 63 ( divide both sides by 9 )

h = 7

A plot of 1/no2 versus time is linear. using this information, identify the factor by which the rate will increase in model (c)
WITCHER [35]
This is hard in mathematical language, but there is only this way to present it. Let us denote by A the consentration of the substance and by A' its rate.
We have that b/A= t+c where c is a constant.
Hence A=b/(c+t)
By differentiating, we get that A'=-b/(C+t)^2
Then, we have that -(A)^2=A'/b
Hence at any point, we have that if we make the concentration 17 times, we have that there is a 17 times bigger , the rate will become bigger by 17*17, hence 289 times faster.

F(x)3x+5/x what is f(a+2)
Natalija [7]
F(X) = (3x + 5)/X
F(a + 2) = (3(a + 2) + 5)/(a + 2)
F(a + 2) = (3a + 6 + 5)/(a+2)
F(a + 2) = (3a + 11)/(a + 2).

This would be the final solution.
