boyakko [2]

Answer:

7.25cm

Step-by-step explanation:

Let the complete question be;

<em>Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.</em>

<em />

Area of a trapezoid = 1/2(a+b)*h

a and b are the parallel sides (bases)

h is the height

Given

a = 3.5cm

b = 8.5cm

A = 43.5 sq.cm

Required

Height h

Substitute the given values into the expression

Area of a trapezoid = 1/2(a+b)*h

43.5 = 1/2(3.5+8.5)*h

43.5 = 1/2 * 12h

43.5 = 6h

h = 43.5/6

h = 7.25cm

Hence the height is 7.25cm

Select the appropriate values of x that are solutions to f (x)=0, where f (x) = -7x^2 +4x+9
Ghella [55]
-7x^2 +4x+9=0\\&#10;\Delta=4^2-4\cdot(-7)\cdot9=16+252=268\\&#10;\sqrt{\Delta}=\sqrt{268}=2\sqrt{67}\\&#10;x_1=\frac{-4-2\sqrt{67}}{2\cdot(-7)}=\frac{-4-2\sqrt{67}}{-14}=\frac{2+\sqrt{67}}{7}\approx1.46\\&#10;x_2=\frac{-4+2\sqrt{67}}{2\cdot(-7)}=\frac{-4+2\sqrt{67}}{-14}=\frac{2-\sqrt{67}}{7}\approx-0.88\\
