Answer:

Step-by-step explanation:

Find the value of f(x) at both points

f(3) = 3(3)³ + 1 = 82

f(1) = 3(1)³ + 1 = 4

---------------------------

Average Rate of Change is just like slope

Divide the change in f(x) by the change in x

r = (82 - 4) / (3 - 1)

r = 78/2

r = 39

The diameter of a circle is 1.4 centimeters. Find its area. Use 3.14 Round to the nearest

NeTakaya

Answer:

Area = 1.54

Step-by-step explanation:

Area = π $r^{2}$

π = 3.14

diameter = 1.4

radius (half of diameter) = 0.7

Area = 3.14 x $0.7^{2}$

Area = 3.14 x 0.49

Area = 1.5386

round to the nearest hundredth:

1.5386 = 1.54

Determine the value of $a$. [asy] pair w=(0,4); pair x=(0,0); pair y=(4,0); pair z=y+7/sqrt(2)*(1,1); dot(w); dot(x); dot(y); do

Answer:

a=7

Step-by-step explanation:

The image is rendered and attached below.

Triangle WXY is an Isosceles right triangle, since WX=XY.

First, we determine the length of WY using Pythagoras Theorem.

$WY=\sqrt{4^2+4^2}\\WY=\sqrt{32}$

Since triangle WXY is Isosceles, $\angle XYW=45^\circ$

$\angle XYZ=\angle XYW+\angle WYZ\\135^\circ=45^\circ+\angle WYZ\\\angle WYZ=135^\circ-45^\circ=90^\circ$

Therefore:

Triangle WYZ is a right triangle with WZ as the hypothenuse.

Applying Pythagoras Theorem

$WZ^2=WY^2+YZ^2\\9^2=(\sqrt{32})^2+a^2\\a^2=81-32\\a^2=49\\a^2=7^2\\$Therefore: a=7$

Drupady [299]

The value written as 2/7 is a rational number and the other options are irrational numbers.

<h3>What is a rational number?</h3>

A rational number is a number that does not end in a non terminating decimal. Surd forms as well as the value pi are all irrational numbers. We must note that the option that has no surd form or pi as a denominator is a rational number.

Hence; the value written as 2/7 is a rational number and the other options are irrational numbers.
