What are the the transformations of h(x)= -f(x+4)-12

katrin [286]

given f)x) then

- f(x) represents a reflection in the x-axis

f(x + 4 ) represents a shift of 4 units horizontally to the left

f(x) + 12 represents a vertical shift of 12 units down

thus h(x) = f(x + 4 ) - 12

is the graph of f(x), moved 4 units left, 12 units down and reflected in the x- axis

to find the area of a trapezoid dylan uses the formula A=1/2 (B1+B2)h the bases have lengths of 3.6 cm and 12 1/3 cm. the height

Artemon [7]

Answer:

It is irrational because it can not be represented as a fraction of two integers

Step-by-step explanation:

Given

$B_1 = 3.6$

$B_2 = 12\frac{1}{3}$

$H = \sqrt[3]5$

Required

Why is the area irrational?

First, we need to calculate the area

$Area = \frac{1}{2}(B_1 + B_2) * H$

$Area = \frac{1}{2}(3.6 + 12\frac{1}{3}) * \sqrt[3]5$

$Area = \frac{1}{2}(3.6 + \frac{37}{3}) * 17100$

$Area = \frac{1}{2}(\frac{10.8+37}{3}) * 1.710$

$Area = \frac{1}{2}(\frac{47.8}{3}) * 1.7100$

$Area = \frac{47.8}{6} * 1.7100$

$Area = \frac{47.8* 1.7100}{6}$

$Area = \frac{81.738}{6}$

$Area = 13.623$

<em>It is irrational because it can not be represented as a fraction of two integers</em>

What’s the missing angle

Alex Ar [27]

Answer:

A) 150

Step-by-step explanation:

All the angles in a triangle must add up to a total of 180 degrees.

So we can make an equation as given below:

20+10+?=180

30+?=180

?=150

So the missing angle is 150 degrees
