Answer:

f(-1) = -19

Step-by-step explanation:

Using the equation

(f(x) = -11 + 8x) we use f(-1) into it.

f(-1) = -11 + 8(-1)

f(-1) = -11 -8

f(-1) = -19

LekaFEV [45]

The correct answer is 7.2 inch.

<h3>What is meant by distance?</h3>
  • The length of the path joining two points determines their distance from one another.
  • The entire journey that an object has taken can be used to define distance. An illustration. If an automobile drives 5 km east, then turns and drives 8 km further north, the total distance driven by the car is 13 km.
  • 'Distance' can be a verb or a noun, as was said above. He set himself apart from the remarks made by several of his coworkers. Thirty miles separate Peterborough from the nearest point. He had pledged to complete this duty but fell short of his commitment.
  • The length of the line segment connecting any two points is referred to as their distance. In coordinate geometry, the distance between two points can be computed by measuring the length of the line segment connecting the two points.

The nearest tenth of a 7inch.

What is the perimeter, in cm, of quadrilateral ABCD if Line AB is perpendicular to Line BC, Line DC is perpendicular to Line BC,
Talja [164]

Answer:

38cm

Step-by-step explanation:

The perimeter of the quadrilateral

ABCD=AB+BC+DC+AD.

From the question,

AB =9cm, BC=12cm and DC=4cm.

This implies that we need to find the length AD before we can proceed to find the perimeter.

From the diagram, we can find |AD| using Pythagorean Theorem.

{|AD|}^{2} =  {12}^{2}  +{5}^{2}

{|AD|}^{2} =144+ 25

{|AD|}^{2} =169

Taking positive square root of both sides

|AD|= \sqrt{169}

|AD|=13 \: cm

Hence the perimeter

=9+12+4+13

=38cm
