Which statements are true about the graph of
Yuri [45]

Answer:

The area below the line is shaded.

Step-by-step explanation:

Using the zero-interval test [test point (0, 0)], we plug in 0 for both <em>y</em><em> </em>and <em>x</em><em> </em>to determine whether we shade <em>below the </em><em>line</em><em> </em>[the portion that DOES contain the origin] or <em>above</em><em> </em><em>the</em><em> </em><em>line</em><em> </em>[the portion that does not contain the origin]. This is where me must verify the inequality as false or true:

\displaystyle 0 < 2[0] + 1 → 0 < 1

This is a genuine statement, therefore we shade <em>below</em><em> </em><em>the</em><em> </em><em>line</em>.

I am joyous to assist you anytime.

Answer:

52√3 ft ²

Step-by-step explanation:

Formula for area of the trapezoid:

A=\frac{a+b}2h

a = Base = 11

b = Base = 15

h = Height = 4√3

Since the height is  4√3 we can turn it into a number:

4√3 = 6.92820323028 = 6.93

Now using the formula:

A=\frac{a+b}2h=\frac{11+15}2\times6.93=90.06664 =90.07

As you can see that it not a answer choice.

We can turn the answer choice into number:

44√3 ft ² = 76.21023553.. ≈ 76.20

44√3-24 ft ²=52.21023553.. ≈ 52.20

60√3 ft ² = 103.92304845.. ≈ 103.90

52√3 ft ² = 90.06664199.. ≈ 90.07

Thus, the answer is 52√3 ft ²

PLEASE HELP ME EVERYONE HAS GOTTEN THIS WRONG ITS GONNA SUBMIT IN 15 MIN PLS HELP THANK YOU

Answer:

x=4.8

This here you use Pythagorean Theorem.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is c. And the two legs are a and b.

So it'd be 11^2+x^2=12^2

121+x^2=144

Subtract 121 from both sides.

x^2=23

Then take the √ of x^2 and 23

So √x^2=√23

x=4.8

Hope this helps
