Answer 2

Answer:

[tex]a =8[/tex]

Step-by-step explanation:

[tex]-7 - 3a = 1 - 4a[/tex]

add [tex]3a[/tex] to both sides

[tex]-7 - 3a + 3a = 1 -4a + 3a \\-7 = 1 -a[/tex]

add [tex]-1[/tex] to both sides

[tex]-7 - 1 = 1 - a -1\\-8 = -a[/tex]

multiply both sides by [tex]-1[/tex]

[tex]-8 * (-1) = -a * (-1) \\8 = a[/tex]

Solve for x.

Enter your answer, including the inequality symbol, in the boxes.

Answers

Answer:

[tex]x\leq6\text{ or } x>30[/tex]

Step-by-step explanation:

We are given the compound inequality:

[tex]\displaystyle 9x+4\leq 58\text{ or } \frac{1}{6}x-2>3[/tex]

Note that this is an "or" inequality. In other words, we just have to solve each inequality individually and then combine the answers!

1)

We have:

[tex]9x+4\leq58[/tex]

Subtract 4 from both sides:

[tex]9x\leq54[/tex]

Divide both sides by 9:

[tex]x\leq6[/tex]

So, our first solution is all numbers less than or equal to 6.

2)

We have:

[tex]\displaystyle \frac{1}{6}x-2>3[/tex]

Add 2 to both sides:

[tex]\displaystyle \frac{1}{6}x>5[/tex]

To cancel out the fraction, let's multiply both sides by 6. So:

[tex]\displaystyle 6\left(\frac{1}{6}x\right)>6(5)[/tex]

The left side will cancel. Therefore:

[tex]x>30[/tex]

So, our second solution is all numbers greater than 30.

Therefore, our full solution will be:

[tex]x\leq6\text{ or } x>30[/tex]

[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].

Determine the remaining sides and angles of the triangle ABC.
A. 18.95 degree.
B. 0.56 degree.
C. 17.83 m.

Answers

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]

[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].

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°

What are complementary angles?

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°

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.

A local rumor, that Mrs. O'Learys cow started the blaze by kicking over a lantern is probably not true. But that legend stuck in the public mind and holds fast to this day(Mcnamara). While the infamous story of Mrs. O'Leary and her cow is still believed by many, the real culprits of the fire were blatantly a long-lasting summer drought and a city built of wood. The legend commences when the family's cow knocks over a lighted lantern, however, Catherine O'Leary dismissed the charges. The circumstances were perfect for the fire to advance, and once it went past the neighborhood close by O'Leary's barn it hastened quickly. Burning cinder came down on furniture factories and grain storage elevators, and soon the flames began to devour everything in its track. Although this is a very convincing story, this was most likely not the case, and the true cause of the raging fire has never been decided. Hence, the unknown cause of the fire. Therefore this led people to believe that the fire was caused by the dry gusts of winds the area experienced during and before the time of the Great Chicago Fire or the unbelievable tale of Olearys cow. The only reaction to the fire was to try to escape, and tens of thousands of Chicago's citizens did. It has been estimated that a fourth of the citys precisely 330,000 residents took to the streets, bringing what they could in alarm. By the time the sun had risen on Monday morning, most of Chicago was already burned completely to the ground. Wooden buildings had simply disappeared into piles of ash and cinder whilst sturdier buildings of brick or stone were charred ruins, leaving most of the residents homeless. The cost of the destroyed property was estimated at $190 million and more than 100,000 people were left without a house. The result of the Great Chicago Fire, the city was left with almost nothing and had to rebuild from the ground up.While the Great Chicago Fire was one of the 19th century's major disasters and a deep blow to the city, the city was rebuilt fairly rapidly. And with the rebuilding came better construction and much stricter fire codes. Inflicting lessons of Chicago's destruction affected how other cities were managed. The Great Chicago Fire burned and destroyed over 17,500 buildings and in the process killed over 300 people. While the fire was the result of the dry and windy weather of Chicago, many lives could've been saved. Not only lives but homes and businesses, as well as the livelihood of these people. Not only was it the dry weather, but human error as well as many people failing to do their jobs in these times of events. While most people blame Mrs. Oleary or the conditions of the weather, it was in all honesty, the errors made by all the people.
