Find the distance between the origin and the point R = (9,7,8). The distance is: Ensure that you use at least 4 decimal place ac
gregori [183]

Answer:

The distance between the origin and the given point is 13.9283 units.  

Step-by-step explanation:

The coordinates of origin are (0,0,0)

We are given a point R(9,7,80

The distance formula:

\sqrt{(y_1 -x_1)^2 + (y_2 -x_2)^2 + (y_3 -x_3)^2}, where (x_1, x_2, x_3) are coordinates of one point and  (y_1, y_2, y_3) are coordinates of other point.

Putting the values as:

y_1 = 9, y_2 = 7, y_3 = 8\\x_1 =0, x_2 = 0, x_3 = 0

We get d = \sqrt{81 + 64 + 49}

d = \sqrt{194}

d = 13.9283

Thus, the distance between the origin and the given point is 13.9283 units.

Please help me!<br> Find AC
oksian1 [2.3K]
We are asked to find the length of AC, which measures 7x. Using the segment addition postulate, we can add the two given expressions for AB and BC and make it equal to the expression for AC. 
AB + BC=AC
5x+1+15=7x
5x+16=7x
16=2x
x=8
We've found the value of x, but we aren't done yet. We need to plug in the value we got for x into the expression for AC, which is 7x. Therefore, AC \Rightarrow7x\Rightarrow7(8)\Rightarrow\boxed{56}. Hope this helped and have a great day!

Find the volume of a cuboid with sides that measure two centimetres, three centimetres and seven centimetres
wariber [46]

Answer:

Volume of a cuboid = 42 cm³

Step-by-step explanation:

Volume of a cuboid = side A × side B × side C

Side A = 2 cm

Side B = 3 cm

Side C = 7 cm

Volume of a cuboid = side A × side B × side C

= 2 cm × 3 cm × 7 cm

= 42 cm³

Volume of a cuboid = 42 cm³

During a pumpkin launching contest, two pumpkins are launched at the same time. The path of pumpkin A is modeled by the equation
amid [387]
You just need to solve for x in the equation:
–0.01x^2 + 0.32x + 4 = <span>–0.01x^2 + 0.18x + 5
0.18x=1
x= 5.55
h(5.55) = -0.01*30.86+0.18*5.55+5 = -0.3086+1+5=5.6914

The intersection point is (5.55, 5.69).
I hope that this is the answer that you were looking for and it has helped you.
