Answer: D. $102\ m^2$

Step-by-step explanation:

Given : The surface area of a triangular pyramid is $408 m^2$ .

We know that the total number faces in a triangular pyramid =4

If all the faces of the pyramid are congruent, then the area of one face of this pyramid will be :_

$408\div 4=102\ m^2$

Hence, the area of one face of this pyramid = $102\ m^2$

You damage your car and it will cost $2,700 to repair. You have a $500 deductible. How much will the insurance company pay? A.$5

artcher [175]

Answer:

After finding the money we were short with, we find that Option-b, that is, $2200 is the correct option.

Step-by-step explanation:

Given that the cost to repair the damaged car is $2700. We have $500.

Insurance company is a company that gives the payment of someone's valuable items when they are lost or get damaged. For example, home insurance, car insurance, life insurance and much more.

Here we can see that we are short with $2700 - $500 = $2200.

So, to complete the payment, insurance company will pay $2200.

Clearly, the correct option is Option-b.

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.

babunello [35]

The x-coordinate of the given endpoint will be " $x = 4 \pm 2\sqrt{29}$ ".

According to the question,

The end points are:

$(x_1,y_1) = (4,-1)$
$(x_2, y_2) = (x,9)$

Distance,

$6\sqrt{6}$

As we know,

The distance formula,

→ $Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

By substituting the values, we get

→ $6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}$

→ $216= (x-4)^2+100$

→ $(x-4)^2 = 116$

→ $x-4 = \pm \sqrt{116}$

→ $x-4=\pm 2\sqrt{29}$

→ $x = 4 \pm 2\sqrt{29}$

Thus the above answer is right.

Please help with the following question

sasho [114]

We have:
The generic equation of the line is: y-yo = m (x-xo)
The slope is:
m = (y2-y1) / (x2-x1)
m = (- 2-0) / (3-0)
m = -2 / 3
We choose an ordered pair
(xo, yo) = (0, 0)
Substituting values:
y-0 = (- 2/3) (x-0)
Rewriting:
y = (- 2/3) x
Answer:
The equation of the line is:
y = (- 2/3) x
