Answer:

D) 28.3 cm

Step-by-step explanation:

since this is a scale drawing , a proportion can be used to solve the problem. 1.4/22=1.8/x, then cross multiply and solve and you will determine that the correct answer is 28.3 cm in usatestprep

Which statement regarding the interior and exterior angles of a triangle is true? An exterior angle is supplementary to the adja
Fudgin [204]

The <em><u>correct answe</u></em>r is:

An exterior angle is supplementary to the adjacent interior angle.

Explanation:

An exterior angle of a triangle and its adjacent interior angle form a linear pair. This means they form a straight line, and a straight line has a measure of 180°. Since they combine for a total of 180°, this means they are supplementary.

What is the axis of symmetry for the graph of y – 4x = 7 – x2
eimsori [14]

we know that

The equation in vertex form of a vertical parabola is equal to

y=a(x-h)^{2}+k

where

(h,k) is the vertex of the parabola

and the axis of symmetry is equal to the x-coordinate of the vertex

so

x=h -----> equation of the axis of symmetry

In this problem we have

y-4x=7-x^{2}

Convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y-7=-x^{2}+4x

y-7=-(x^{2}-4x)

Complete the square. Remember to balance the equation by adding the same constants to each side

y-7-4=-(x^{2}-4x+4)

y-11=-(x^{2}-4x+4)

Rewrite as perfect squares

y-11=-(x-2)^{2}  

y=-(x-2)^{2}+11  

the vertex is the point (2,11)

therefore

<u>the answer is</u>

The axis of symmetry is

x=2

see the attached figure to better understand the problem
