Hi!
The answer is 38mi.
Steps:
1.You add the bases together.
2. Then, you divide by 2 or multiply by 0.5.
3. Lastly, you multiply the number you got by the height (10)
2.8+4.8= 7.6/2=3.8
3.8 times 10= 38

Have a nice day!

What is the midpoint of the segment shown below?
kolbaska11 [484]

The midpoint of the segment is (-15/2, -15/2)

<h3>How to determine the midpoint?</h3>

The complete question is in the attached image

The points are given as:

(-8, -7) and (-7, -8)

The midpoint is calculated as:

(x,y) = 1/2 * (x1 + x2, y1 + y2)

So, we have:

(x,y) = 1/2 * (-8 - 7, -7 - 8)

Evaluate the difference

(x,y) = 1/2 * (-15, -15)

Evaluate the product

(x,y) = (-15/2, -15/2)

Hence, the midpoint of the segment is (-15/2, -15/2)

Help pls <br> Find the value of x
elena55 [62]

Answer:

x=61

Step-by-step explanation:

Because it is a 90 degree angle, you subtract the 29 from 90 and you get 61. You can also put in in this equation and arrive at the same conclusion.

90=X+29

302 + 12 M equals 278
slavikrds [6]
In the given question there is an equation that has to be solved and the value of the unknown variable "M" has to be determined. It is absolutely possible to find the exact value of the variable "M" as there is 1 equation and 1 variable.
302 + 12 M = 278
12 M = 278 - 302
12 M = - 24
M = - (24/12)
   = - 2
So the value of the unknown variable "M" comes out to be -2. I hope the procedure is clear enough for you to understand and also this is the answer you were looking forward to.

construct a polynomial function with the stated properties. third degree with zeros of -2,-1, and 3 and passes through the point
AfilCa [17]

Answer:

f(x) =  - (x + 2)(x + 1)(x - 3)

Step-by-step explanation:

Let f(x) be the 3rd degree polynomial function.

The roots of this function are:

x=-2, x=-1 and x=3.

The factored form is:

f(x) = a(x + 2)(x + 1)(x - 3)

This equation passes through (2,12)

This implies that;

a(2 + 2)(2+ 1)(2 - 3) = 12 \\  - 12a = 12 \\ a =  - 1

The polynomial function is

f(x) =  - (x + 2)(x + 1)(x - 3)
