Y=1/3x+4 going through the point (9,-2)

1 answer:

5 0

Substitute x=9 and y=-2 into equation,
Left hand side=-2
Right hand side=1/3(9)+4= 3+4=7

Because LHS doesn’t = with RHS, the point (9,-2) doesn’t satisfy with the equation

Therefore the point doesn’t go through y=1/3x +4.

Suppose you drop a tennis ball from height of 16 feet . Each time the ball bounces off the floor,it reaches half of its previous

Fiesta28 [93]

We can solve this problem by division- What information can we gather?

The ball reaches half its original hight each time it bounces, which is another way of saying it divides by 2 each time

It bounced three times.

If we divide 16 by 2, we get 8.
If we divide 8 by 2, we get 4
If we divide 4 by 2, we get 2.

<em>The answer is 2</em>

Hope this helps!

Answer:

Area: 15.53 square inches

Perimeter: 15.71 inches

Step-by-step explanation:

Area:

So the area of the rectangle is pretty easy to find and is just the width * height. In this case it's 4 * 3 which is 12. Now the area of a circle is $\pi r^2$ . But since this is a semi circle it's half of that which is $\frac{\pi r^2}{2}$ . The diameter of the semicircle is 3 as it sits on top of the rectangle. The radius is half of the diameter so the radius is 1.5. Now plug that into the equation and you get $\frac{(3.14) (1.5)^2}{2} = 3.5325$ . Now add that to 12 and you get 15.5325. Round that number to the nearest hundredth and you get 15.53. So that's the area.

Perimeter:

Pi is the ratio of any circle's circumference to the diameter. Or in other words the circumference is equal to the diameter * 3.14. The diameter is 3 which you multiply by 3.14 to get the circumference of a circle. This will get you 9.42 but since it's a semicircle, the circumference is half of this value which is 4.71. The perimeter of the rectangle is just 2 times the width + 2 times the height. This is not completely the case in this shape since one of the sides of the rectangle is not a side of the two shapes joined together. Which is the side that is parallel to the side of length 3 inches. So the perimeter is going to be 2(4) + 3. This gives you 11 which you add to the 4.71 and get 15.71
