1.Find the area of a trapezium with parallel sides of
Nana76 [90]

Answer:

The area of the trapezium is 74.8\ cm^2

Step-by-step explanation:

Area of a trapezium:

\displaystyle A=\frac{b1+b2}{2}h

This formula is valid if b1 and b2 are parallel and h is perpendicular to both.

Since the trapezium given in the problem satisfies those conditions, we use the formula with:

b1=15 cm

b2=7 cm

h=6.8 cm

\displaystyle A=\frac{15+7}{2}\cdot 6.8

A=74.8\ cm^2

The area of the trapezium is 74.8\ cm^2

ratelena [41]
<span> The answer is is 4 times. </span>
<span>The reason it is 4 is because 3 times 4 is 12 and 12 is less than 14. If you did 3 quarters times 5, you would get 15, going over the limit.</span>

Find all solutions of the equation sin^2 x=2sinx+3
Mashutka [201]
\sin^2x=2\sin x+3
\sin^2x-2\sin x-3=0
(\sin x-3)(\sin x+1)=0

which means either \sin x=3 or \sin x=-1. The equation has no solution, since \sin x is always bounded between -1 and 1. The second has one solution at x=-\dfrac\pi2, and any number of complete revolutions will also satisfy this equation, so in general the solution would be -\dfrac\pi2+2k\pi where k is any integer.

So you could choose A=-\dfrac\pi2 and B=2.
