Answer: The area is 12.5 units squared

Step-by-step explanation: The trapezoid shown has the parallel lines (bases a and b) given and the vertical (perpendicular) height also given.

The area of a trapezoid is calculated as ;

Area = [(a + b)/2] x h

Where a is 2.5, b is 7.5 and h is 2.5

Area = [(2.5 + 7.5)/2] x 2.5

Area = [(10)/2] x 2.5

Area = 5 x 2.5

Area = 12.5 units squared

The slope of the line is $m=-\frac{1}{2}$

Explanation:

Given that a coordinate plane with a straight line passing through the points $(-4,2)$ , $(0,0)$ and $(4,-2)$

We need to determine the slope of the line.

The slope of the line can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Since, the points $(-4,2)$ , $(0,0)$ and $(4,-2)$ lie on the straight line and the slope of all the points in a straight line have the same slope.

Hence, let us consider the points $(-4,2)$ and $(0,0)$

Let us substitute these points in the slope formula, we have,

$m=\frac{0-2}{0+4}$

Simplifying, we get,

$m=\frac{-2}{4}$

Dividing, we get,

$m=-\frac{1}{2}$

Hence, the slope of the line is $m=-\frac{1}{2}$

Answer:

a=3 and b=-2

Step-by-step explanation:

We are given that five terms of a quadratic sequence are

1 8, 21, 40, 65.

The nth term of this sequence

= $an^2+bn$

We have to find the value of a and b where a and b are integers.

For n=1

$a+b=1$ ......(1)

For n=2

$(2)^2a+2b=8$

$4a+2b=8$

$2a+b=4$ .....(2)

Subtract equation (1) from (2) we get

$2a-a=4-1=3$

$a=3$

Using the value of a=3 in equation (1)

$3+b=1$

$b=1-3=-2$

Hence, the value of

a=3 and b=-2
