9514 1404 393

Answer:

11.2
0.24

Step-by-step explanation:

The area is the same, regardless of which side is considered the "base"

A = bh

1. A = 8×14 = 10h

h = 8×14/10

h = 11.2

2. A = 0.3×0.4 = 0.5h

h = 0.3×0.4/0.5

h = 0.24

Distance formula derived from Pythagorean theorem

allsm [11]

Answer:

The Distance Formula itself is actually derived from the Pythagorean Theorem which is a 2 + b 2 = c 2 {a^2} + {b^2} = {c^2} a2+b2=c2 where c is the longest side of a right triangle (also known as the hypotenuse) and a and b are the other shorter sides (known as the legs of a right triangle).

1.Find the slope of the line through (-6, 11) and (15, 20).

GrogVix [38]

Answer:

$\boxed {\boxed {\sf m= \frac{3}{7} }}$

Step-by-step explanation:

We are asked to find the slope of a line. The slope tells us the steepness and direction of a line. It is found by dividing the change in y by the change in x.

$m= \frac{ \Delta y }{\Delta x}$

$m= \frac{y_2-y_1}{x_2-x_1}$

In this formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through. We are given the points (-6, 11) and (15,20). If we match a value with its corresponding variable, we see that:

x₁ = -6
y₁ = 11
x₂ = 15
y₂ = 20

Substitute the values into the formula.

$m= \frac{20-11}{15 - -6 }$

Solve the numerator.

$m= \frac{9}{15--6}$

Solve the denominator. 2 back to back negative signs become a positive sign.

$m= \frac{9}{15+6}$

$m= \frac{9}{21}$

Simplify the fraction. 3 divides evenly into the numerator and denominator.

$m= \frac{9/3}{21/3}$

$m= \frac{3}{7}$

The slope of the line is <u>3/7.</u>
