Answer:

10 units

Step-by-step explanation:

(x_1,y_1)=(-3,-8)

(x_2,y_2)=(10,-8)

We are supposed to find the length of the line segment with endpoints (−3,8) and (7, 8)

We will use distance formula : d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the values :

d=\sqrt{(10+3)^2+(8-8)^2}

d=\sqrt{100}

d=10

Hence the length of the line segment with endpoints (−3,8) and (7, 8) is 10 units

Answer:

13 units

given two points: (−3, −8) and (10, −8)

As the y coordinates are same.

use the method:

|x2| + |x1|  where  (x1, y1), (x2, y2)

Solve:

|10| + |-3|

10 + 3

13

Length of the bases and h is the height, to answer the question. How many square feet of grass
Aleonysh [2.5K]

Answer:

There are 7,725 square feet of grass on the trapezoidal field

Step-by-step explanation:

Here in this question, we are interested in calculating the square feet of grass present on the trapezoidal field.

What this question is actually asking us is to calculate the area of the trapezoid-shaped grass field.

To calculate this area, what we need to do

simply is to use the formula for the area of a trapezoid.

Mathematically, the area of a trapezoid can be calculated using the formula;

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

where a and b refers to the length of the parallel lengths of the trapezoid and h refers to the height of the trapezoid.

From the question;

a, b = 81ft and 125 ft

h = 75 ft

Substituting these values, we have :

Area = 1/2 * (81 + 125) * 75

Area = 1/2 * 206 * 75 = 83 * 75 = 7,725 ft^2

I need help with point slope formula bad
NISA [10]
Ok so this question:
y + 1 = - ( x - 2 )        (distribute the negative inside the parenthesis)
y + 1 = -x + 2             (substitute the y= -1)
-1 + 1 = -x + 2
0 = -x + 2                   (take two to the other side)
-2 = -x                        (divide the negative away from x)
2 = x

Can someone please help me :)
gavmur [86]

Answer:

<em>90 degree</em>

Step-by-step explanation:

Three points A, B, and C are added and shown in attached picture.

As the property of inscribed angle in circle:

angle BAC = (1/2) x 88 = 44 deg

As the property of complement angle:

angle ABC = 180 - 89 = 91 deg

As the property of sum of three angles in a triangle:

angle ACB + angle ABC + angle BAC = 180 deg

=> angle ACB = 180 - angle ABC - angle BAC = 180 - 44 - 91 = 45 deg

One more time, we use the property of inscribed angle in circle:

x = 2 x angle ACB = 2 x 45 = 90 deg

Hope this helps!
