A line includes the points (-3, 8)and (-1, 2). What is its equation in slope- intercept form

1 answer:

5 0

Solve for slope first:
m = $\frac{y2 - y1}{x2 - x1}$

m = $\frac{2-8}{-1-(-3)}$ = -3

then solve for b in y = mx + b

8 = -3(-3) + b
b = -1

y = -3x - 1

The bases of the trapezoid are 6 and 10. The height is 4. Find the area.

ollegr [7]

Answer

b. 32 sq. unit

Step-by-step Explanation

The area of the trapezoid is given by

$A = \frac{1}{2} (b_{1} + b_{2}) \times h$

We substitute the given values into the formula to obtain;

$A = \frac{1}{2}(10 + 6) \times 4$

Simplify

$A = \frac{1}{2} (16) \times 4$

$A = 16 \times 2$
Hence the area is

$A = 36 \: sq \: units$

I need help with no.7

ziro4ka [17]

Answer:

(a) 315°

(b) 3°

Step-by-step explanation:

Bearings are measured clockwise from north. The triangle described is illustrated in the attachment.

The bearing of P from R is 180° different from the bearing of R from P it will be ...

135° +180° = 315° . . . . bearing of P from R

The bearing of Q from R is 48° more than the bearing of P from R, so is ...

315° +48° = 363°, or 3° . . . . bearing of Q from R

The angle QPR has a value that makes the sum of angles in the triangle equal to 180°. It is ...

180° -48° -55° = 77°

The bearing of Q from P is 77° less than the bearing of R from P, so is ...

135° -77° = 58°

As above, the reverse bearing from Q to P is ...

58° +180° = 238° . . . . bearing of P from Q

What is the area of the composite figure?

mars1129 [50]

Answer:

34.9^2

Step-by-step explanation:

Well if one side is 4 cm then the square is 16cm^2.

The area of a circle is pi r^2.

So the radius is 2.

we plug 2 in.

pi 4

12.6/2

6.3

6.3 * 3 = 18.9cm^2

18.9 + 16 = 34.9
