Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 165°}}}}}[/tex]

Step-by-step explanation:

Sum of complete turn adds up to 360°

Given angles : 63° , 42 ° , 90 ° , x°

To find : x

Create an equation

[tex] \sf{x + 63° + 42° + 90° = 360°}[/tex]

[tex] \dashrightarrow{ \sf{x + 195° = 360°}}[/tex]

[tex] \dashrightarrow{ \sf{x = 360° - 195°}}[/tex]

Answer:

[tex]\huge\boxed{ \text{(A)}\ \ \frac{1}{10}, -\frac{1}{10}}[/tex]

Step-by-step explanation:

We can simplify this expression down so that we have x isolated on one side of the equation.

So we can take the square root of both sides.

[tex]x = \sqrt{\frac{1}{100}}[/tex]

The square root of [tex]\frac{1}{100}[/tex] will be the number that, when multiplied by itself, will get us [tex]\frac{1}{100}[/tex].

In order to find the square root of a fraction, the numerator squared must correct and the denominator squared must be correct.

[tex]1^2 = 1[/tex]

[tex]10^2 = 100[/tex]

This means that we have the values 1 and 10. Therefore one of our fractions is [tex]\frac{1}{10}[/tex].

HOWEVER: A negative number squared is a positive. So this also works:

[tex]-1^2 = 1\\\\-10^2=10[/tex]

So we have [tex]-\frac{1}{10}[/tex] along with  [tex]\frac{1}{10}[/tex].

Answer:

x=60

Step-by-step explanation:

here DOB and AOC are vertically opposite angles and the values of them are equal. so lets take the two angles as y.

x+DOB is 90(because EOA is 90 and the sum of angles in a straight line is 180), DOB is y and can write a equation as x+y=90

and 30+2x+y = 180 ,

2x+y=150, (180-30)

then two equations can be made.

x+y=90

2x+y=150

simplifying these two simultaneous equations

can get x as 60. and 2x is 120.

The value of x is 60°

The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.

Here, DOB and AOC have equal values and are at vertically opposed angles. Let's use y to represent the two angles.

Since EOA is 90 and the total of the angles in a straight line is 180, x+DOB equals 90 and can be written as x+y=90.

And 30 + 2x + y = 180 ,

⇒ 2x+y = 180-30

⇒ 2x + y = 150,

After which two equations can be created.

⇒ x+y=90

⇒ 2x+y=150

We have the two simultaneous equations made simpler.

We can get x as 60. and 2x as 120.

Thus, the value of x is 60°

Answer:

1872

Step-by-step explanation:

Plug is 16 for x

f(x)=13(4−x)^2

f(16)=13(4−16)^2

f(16)=13(-12)^2

-12^2=144

f(16)=13(144)

f(16)=1872

Hope this helps! Plz award Brainliest : )

The value of function f(x)= 13(4 - x)² at x= 16 is 1872.

To find the value of f(16), we substitute x = 16 into the expression for f(x) and evaluate it.

f(x) = 13(4 - x)²

Substituting x = 16:

f(16) = 13(4 - 16)²

Now, let's calculate:

f(16) = 13(-12)²

      = 13(144)

      = 1872

Therefore, the value of f(16) is 1872.

Answer:

Angle C  ∠C = 160.49°

side b =  0.522  m

side a = 17.34 m

Step-by-step explanation:

Given that;

In a Δ ABC,

∠A = 18.95°

∠B = 0.56°

∠C = ???

side A = ???

side B = ???

side C = 17.83 m

We are to determine the unknown missing sides and the angle.

We know that, the sum of angles in a triangle = 180°

∴

∠A + ∠B + ∠C = 180°

18.95° + 0.56° + ∠C = 180°

∠C = 180° - 18.95° - 0.56°

∠C = 160.49°

Using sine rule to determine the unknown sides. The sine rule can be expressed as:

[tex]\mathtt{\dfrac{sin \ A}{a} = \dfrac{sin \ B}{b} = \dfrac{sin \ C}{c} }[/tex]

To determine side b, we have:

[tex]\mathtt{ \dfrac{sin \ B}{b} = \dfrac{sin \ C}{c} }[/tex]

[tex]\mathtt{ \dfrac{sin \ 0.56^0}{b} = \dfrac{sin \ 160.49}{17.83} }[/tex]

[tex]\mathtt{ b (sin \ 160.49) = 17.83 (sin \ 0.56)}[/tex]

[tex]\mathtt{ b = \dfrac{17.83 (sin \ 0.56)}{(sin \ 160.49)}}[/tex]

[tex]\mathtt{ b = \dfrac{17.83 \times 0.0097737}{0.33397}}[/tex]

[tex]\mathtt{ b = \dfrac{0.174265071}{0.33397}}[/tex]

b  = 0.522  m

For side a, we have

[tex]\mathtt{\dfrac{sin \ A}{a} = \dfrac{sin \ B}{b} }[/tex]

[tex]\mathtt{\dfrac{sin \ 18.95}{a} = \dfrac{sin \ 0.56}{0.522} }[/tex]

[tex]\mathtt{a \times sin \ 0.56 = 0.522 (sin \ 18.95)}[/tex]

[tex]\mathtt{a = \dfrac{0.522 (sin \ 18.95)}{ sin \ 0.56}}[/tex]

[tex]\mathtt{a = \dfrac{0.522\times 0.3247 }{ 0.0097737}}[/tex]

a = 17.34 m

                 [tex]\frac{d y}{d x} = \frac{-1}{2 (3)}[/tex]

[tex]\boxed{\bold{[C] \ \ \ \ \frac{1}{3^5} } }}[/tex]

Explanation:

Apply Exponent Rule: [tex]\bold{\:a^{-b}=\frac{1}{a^b}}[/tex]

[tex]\bold{3^{-5}: \ \frac{1}{3^5} }[/tex]

The equivalent expression for [tex]3^{-5[/tex] using exponent is [tex]\( \dfrac{1}{3^5} \)[/tex].

Explanation:

When we have a negative exponent, it indicates the reciprocal of the base raised to the positive exponent.

In this case, [tex]3^{-5[/tex] means the reciprocal of [tex]3^5[/tex].

To compute [tex]\( 3^5 \)[/tex] raise 3 to the power of 5, which gives us

[tex]\( 3^5 = 3 \times 3 \times 3 \times 3 \times 3 = 243 \)[/tex]

Now, to get the reciprocal of 243,

simply take [tex]\( \dfrac{1}{243} \)[/tex], which is the same as [tex]\( \dfrac{1}{3^5} \)[/tex].

So, [tex]\( 3^{-5} = \dfrac{1}{3^5} = \dfrac{1}{243} \)[/tex].

2(3(7)-1)

= 2(21-1)

=2(20)

=40

Dividing any positive number m over (m+1) leads to a positive result that is smaller than one. This is because the denominator is larger than the numerator.

However, if m is negative, then it's a different story. Consider m = -2

If m = -2, then m+1 = -2+1 = -1

Meaning that [tex]\frac{m}{m+1} = \frac{-2}{-1} = 2[/tex] but this result is not less than 1

So m = -2 is one counterexample of infinitely many to show that [tex]\frac{m}{m+1} < 1, \text{ with } m \ne -1[/tex] is not always true. If you restricted m to be positive, then the inequality would be true.
