What is the distance between the points (3,7) and (15,16) on a coordinate plane?

mamaluj [8]

distance = Sqrt((x2-x1)^2 +(y2-y1)^2)

15-3 =12

16-7=9

12^2 = 144

9^2 = 81

144+81 = 225

square root of 225 = 15

the distance is 15

Santa Claus loves to drop presents out of his sled during Christmas. The height above the ground of one present after t seconds

Ahat [919]

Answer:

The present was 300 feet above ground 5 seconds after being thrown.

6.47 seconds passed before the present hit the ground.

Step-by-step explanation:

We have the following quadratic function

$h(t) = -16t^{2} - 20t + 800$

Which determines the height of the present.

Determine when the present was 300 feet above the ground.

This is when $h(t) = 300$ . So

$h(t) = -16t^{2} - 20t + 800$

$300 = -16t^{2} - 20t + 800$

$-16t^{2} - 20t + 500 = 0$

This is $t = -6.25$ and $t = 5$ . There are no negative time instants. So the present was 300 feet above ground 5 seconds after being thrown.

Determine how many seconds passed before the present hit the ground.

This is t when $h(t) = 0$

$h(t) = -16t^{2} - 20t + 800$

$-16t^{2} - 20t + 800 = 0$

$t = 6.47$

6.47 seconds passed before the present hit the ground.

Here is a five-sided polygon. Describe or show the strategy you would use to find its area. Mark up and label the diagram to sho

MrRissso [65]

Answer:

i can explai it to u if u wan to get the answer

Step-by-step explanation:

Divide the polygon into 5 triangles by using each side as a base and joining the vertices of the polygon to a common point (for example, the centre). If the polygon is regular the angle at the vertex of each triangle is 360/5=72 degrees, so you have 5 isosceles triangles of equal area. Find the area of one and multiply by 5 to get the total area.multiply 5 times the lenght of oneside

Multiply and simplify if possible square root of 6 multiply square root 2

alex41 [277]

The question is asking us to multiply and simplify the equation square root of 6 times the square root of 2. To do this, we must first transform the whole question into numbers. Doing so, we get:
$\sqrt{6} * \sqrt{2}$
Now, we straight up multiply 6 and 2:
$\sqrt{12} = \sqrt{3} \sqrt{4} =2 \sqrt{3}$
The answer to your problem is $2\sqrt{3}$ . Hope this helps and have a great day!
