An Equilateral Triangle has sides that all measure 10 inches. What is
densk [106]

Answer:

easy peasy lemon squeasy

Step-by-step explanation:

1. base of triangle: it is an equilateral triangle, so any side of the triangle you take is the base, (usually the largest side of the triangle is the base)

so that would be => 10 inches,

2. a property of an equilateral triangle is that , the median of the triangle coincides with the height of the triangle,

therefore, the height bisects the base and makes a right triangle with another side, therefore by using the Pythagoras theorem, we find it to be 8.66(approx)

now,

area of the triangle would be (putting the values we just found in the formula given)

=> [(10)(8.66)]/ 2

=>43.3 square inches

Fro the graph attached,

We have to calculate the value of the function at x = -4.

As we can find from the graph at the input value x = -4, output value of the function is f(-4) = 4

Therefore, f(-4) = 4 will be the answer.

What is the slope of a line that is perpendicular to the line represented by the equation 3x + 4y = 12?
Vikentia [17]

Answer:

-3/4

Step-by-step explanation:

3x+4y=12

get into y=mx+b form first (m is the slope, b is the intercept)

So, 4y=12-3x

Then y=(12/4)-(3/4)*x

So your m is -3/4

Since you said it must be parallel the slope is the same to ensure they never touch
