move numbers to the table to show the value of x that satisfies each question
equation 2^x = 16
4^x = 1/16

Answer:

Step-by-step explanation:

d

The possible rational roots are (a) ±3, (b) ±1, (e) ±5

The polynomial function is given as:

f(x) = 5x^2 - 3x + 3

Take the factors of the first term and the last term

5 = 1, 5

3 = 1, 3

The rational root is then calculated using:

Roots =±(Factors of 3)/(Factors of 5)

This gives

Roots =±(1, 3)/(1, 5)

Solve the expression

Roots = ±1, ±3/5, ±1/5, ±3

Hence, the possible rational roots are (a) ±3, (b) ±1, (e) ±5

Given:

In a right angle triangle θ is an acute angle and [tex]\tan\theta =\dfrac{3}{5}[/tex].

To find:

The value of [tex]\cos \theta[/tex].

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

We have,

[tex]\tan\theta =\dfrac{3}{5}[/tex]

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.

By using Pythagoras theorem,

[tex]Hypotenuse=\sqrt{Perpendicular^2+base^2}[/tex]

[tex]Hypotenuse=\sqrt{(3x)^2+(5x)^2}[/tex]

[tex]Hypotenuse=\sqrt{9x^2+25x^2}[/tex]

[tex]Hypotenuse=\sqrt{34x^2}[/tex]

[tex]Hypotenuse=x\sqrt{34}[/tex]

In a right angle triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos \theta=\dfrac{5x}{x\sqrt{34}}[/tex]

[tex]\cos \theta=\dfrac{5}{\sqrt{34}}[/tex]

Therefore, the value of [tex]\cos \theta[/tex] is [tex]\dfrac{5}{\sqrt{34}}[/tex].

Answer:

8 meters

Step-by-step explanation:

To find the perimeter follow these steps:

1. add the lengths together (the longe sides) so add 3 meters and 3 meters you get 6 meters

2. add the widths together (the short sides) so add 1 meter and 1 meter you get 2 meters

3. add the total lengths and widths together (6 meters plus 2 meters) you get 8 meters

Answer:

[tex]x=80[/tex]°

Step-by-step explanation:

[tex]sum ~of ~3~angles ~of ~a~ triangle ~is ~180[/tex]

[tex]80+20+x=180[/tex]

[tex]x=missing ~angle[/tex]

[tex]100+x=180[/tex]

[tex]x=180-100=80[/tex]

[tex]So, x=80[/tex]

Answer:

No

Step-by-step explanation:

you can check with the pythagorean theory

[tex]8^{2}+9^{2} =12^{2}[/tex]

64 + 81 = 144

145 = 144

this is not true, therefore those side lengths do not make a right triangle.

Answer:

[tex] \displaystyle x \approx 47.44[/tex]

Step-by-step explanation:

we are given a right angle triangle

we want to figure out x i.e hypotenuse

in order to do so we can consider trigonometry i.e sin

remember that,

[tex] \displaystyle \sin( \theta) = \frac{opp}{hypo} [/tex]

given that,theta=21° and opp=17 and hypo=x

Thus substitute:

[tex] \displaystyle \sin( {21}^{ \circ} ) = \frac{17}{x} [/tex]

cross multiplication:

[tex] \displaystyle x\sin( {21}^{ \circ} ) = {17}[/tex]

divide both sides by sin21°:

[tex] \displaystyle x \frac{\sin( {21}^{ \circ} ) }{ \sin( {21}^{ \circ}) }= \frac{17}{ \sin( {21}^{ \circ} ) }[/tex]

By using calculator we acquire:

[tex] \displaystyle x \approx 47.44[/tex]
