Answer:

(25, 29)

Step-by-step explanation:

The midpoint formula can be solved to give an expression for one end point of a line segment in terms of the other end point and the midpoint.

<h3>Formula</h3>

The midpoint (M) of segment AB is found from ...

M = (A +B)/2

Solving for B, we get ...

B = 2M -A

<h3>Application</h3>

For A(-9, -1) and M(8, 14), we find the end point B to be ...

B = 2(8, 14) -(-9, -1)

B = (16 -(-9), 28 -(-1)) = (25, 29)

The other end point is (25, 29.

Answer:

Follows are the description of the given point:

Step-by-step explanation:

Please find the correct question in the attached file.

In point A:

An order of 5 items shall be placed in a total of 6 different ways.

(w for cars and ts and tricycles to be used)

$\to 5w=20 wheels\\\\\to 4w+1t= 19 wheels\\\\\to 3w+2t=18 wheels\\\\\to 2w+3t=17 wheels\\\\\to 1w+4t= 16 wheels\\\\\to 5t=15 wheels\\\\$

In point B:

2 waggons so more tyres would be required if they ordered any more waggons.

$work: \\\\ \to 2 \times 4=8 \\\\ \to 3 \times 3=9 \\ \\ \to 8+9=17$

What is the approximate measure of I

mrs_skeptik [129]

Let θ = m∡I

tan θ = 20/21
tan⁻¹ (20/21) = θ

θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
