A trapezoid has bases that measure 10cm and 6cm. The height of the figure is 15cm. What is the area of the trapezoid?

kati45 [8]

Hello!

To find the area of a trapezoid you use the equation

$A = \frac{a+b}{2} h$

A is area
h is height
a and b are the bases

Put in the values we know

$A = \frac{10+6}{2} *15$

Add

$A = \frac{16}{2} *15$

Divide

$A = 8 * 15$

Multiply

A = 120

The answer is 120cm squared

Hope this helps!

The vertex of this parabola is at (-4,-1).When the y-value is 0,the x-value is 2.What is the coefficient of the squared term in

densk [106]

Answer:

1/36

Step-by-step explanation:

When the coefficient is 1, the function has zeros at -3 and -5, one horizontal unit from the vertex. You want to move the zero to (2, 0), which is 6 units from the vertex. To achieve a horizontal stretch by a factor of 6, the value of x in the function must be replaced by x/6. That would make the coefficient of x^2 be (1/6)^2 = 1/36.

The coefficient of the squared term is 1/36.
