Answer 1

Answer:

Step-by-step explanation:

7x - 42 + 5x =  180  {linear pair}

7x + 5x - 42 = 180              {Combine like terms}

      12x - 42 =180

             12x = 180 + 42

            12x = 222

             x = 222/12

x = 18.5

5x = 5*18.5 = 92.5

7x - 42 = 7*18.5 - 42  = 129.5 - 42 = 87.5

Answer:

The length of each side of the base must be 6.

Step-by-step explanation:

Total volume = 396

Volume = Length x width x height

We know height = 11

So,

11 x Length x Width = 396

396 / 11 = 36

Length x Width = 36

This is a square prism so all sides of base are equal.

Length = 6

Width = 6

And therefore all the other sides of the base are also 6.

In triangle ABC, we can draw a perpendicular line segment from vertex C to segment AB. The intersection of AB and the perpendicular is called E. We know that BE is the shortest distance from B to and that is the shortest distance from A to CE because of the shortest distance theorem. Therefore, BC > BE and AC > AE. Next, add the inequalities: BC + AC > BE + AE. Then, BE + AE = BA because of the . Therefore, BC + AC > BA by substitution.

Find the simple interest earned, to the nearest cent, for the principal, interest rate, and time.



$530, 6%, 1 year

Answers

The simple interest earned on $530 at 5.5% rate for 1 years is $31.80.

How to calculate simple interest?

The formula for simple interest is expressed mathematically as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time period.

Given the data in the question;

Principal P = $530Interest rate r = 6%Time period t = 1 yearInterest I = ?

First, convert the rate from percent to a decimal form

Rate r = 6%

Rate r = 6/100

Rate r = 0.06

To determine the simple interest earned, plug the given values into the simple interest formula and solve for I.

I = P × r × t

I = $530 × 0.06 × 1

I = $530 × 0.06

I = $31.80

Therefore, the simple interest accumulated after 1 years is $31.80.

If tan x = m, what is sin x in terms of m?​

Answers

Answer: m/sqrt(m^2)+1

Step-by-step explanation: if tan x = m, then the opposite angle is m and the adjacent angle is 1 so 1 squared plus m squared equals c squared. c = sqrt (1 + m^2)

sin x = opposite/hypotenuse = m/sqrt(m^2)+1

The value of sin x in terms of m is [tex]\frac{m}{\sqrt {m^2+1}}[/tex]

Trigonometry are identities used to express the sides and angles of a triangle.

According to SOH CAH TOA,

Tan θ = Opposite/Adjacent

Given that tan x = m

Opposite  = m

Adjacent = 1

Get the hypotenuse using the pythagoras theorem

Hyp² = Opp² + Adj²

Hyp² = m²+1²

Hyp² = m²+1

Take the square root of both sides

√Hyp² =√m²+1

Hypotenuse = √m²+1

Next is to get sin x:

Sin x = Opposite/Hypotenuse

Sin x = [tex]\frac{m}{\sqrt {m^2+1}}[/tex]

Hence the value of sin x in terms of m is

[tex]\frac{m}{\sqrt {m^2+1}}[/tex]

O f(x) = 1/2(2)x
O f(x) = 1/2(1/2)x
Of(x) = 2(2)x
PLEASE HELP MEE!

Answers

Answer:

f(x) = [tex]\frac{1}{2}[/tex] [tex](2)^{x}[/tex]

Step-by-step explanation:

Using the standard form of the exponential function

y = a [tex]b^{x}[/tex]

To find a and b , substitute ordered pairs from the graph

Using (0, 0.5 ), then

0.5 = a[tex]b^{0}[/tex] [

a = 0.5 , so

y = [tex]\frac{1}{2}[/tex] [tex]b^{x}[/tex]

Using (1, 1) , then

1 = [tex]\frac{1}{2}[/tex][tex]b^{1}[/tex] , thus

b = 2

f(x) = [tex]\frac{1}{2}[/tex][tex](2)^{x}[/tex] ← exponential function representing graph

Tell how they are the same and different. Also, explain why you chose them. Use facts and details from the Article in your answer.The article: Before there was a world, there was only Chaos, the goddess of nothingness. Then, other immortals surfaced. One is Gaia, the goddess of Earth. Others include Thanatos, the god of death, and Eros, the god of love.From these deities came powerful forces: night and day, fate and doom. They, in turn, created fierce beings. There were giants called Titans and one-eyed monsters called Cyclopes. There were also creatures with 100 hands and 50 heads. These were called Hecatoncheires.The gods often battled each other. In the end, 12 gods and goddesses remained. They ruled the universe from a mountain in the sky.Does this sound like the latest sci-fi adventure? It isn't. These characters from Greek mythology are thousands of years old.Ancient people once built great temples to win the favor of these gods and goddesses. More recently, household items, illnesses, and trips to outer space bear their names. And so, the characters demand attention.Zeus and HeraThere's the mythological deity of Zeus, the king of the gods. He rides a horse with wings and throws thunderbolts when he's angry. He's the lord of justice, yet he can be terribly unfair. In fact, he's a god of many contradictions. He's kind yet cruel. He's playful yet stern. He's a leader yet small-minded. Zeus often pretends to be an animal and drops in on the human world, where he's got a few girlfriends.According to the myths, this angers Zeus's wife Hera. (She's the goddess of marriage after all.) Hera gets jealous and is mean to Zeus's girlfriends and their children. She especially hates Zeus's son Heracles, a super strong warrior. When Heracles was born, Hera sent two snakes to kill him in his crib. It didn't work, according to the stories, And it made Hera try to think of other ways to kill him.Sci-fi action-adventure? How about dysfunctional family?The BrothersIn Greek mythology, Zeus rules the world with his two brothers. One is Poseidon, the god of the sea. The other is Hades, the god of the underworld. (Zeus and Poseidon clearly got the better deal.) Poseidon is as moody as Zeus. Every time he bangs his spear, an earthquake strikes. He may allow seafarers safe passageor not. He is said to be especially hard on a great war hero named Odysseus, who blinded Poseidon's sona big mistake if you need to get home by wooden boat.Hades is also responsible for the seasons. Blame it all on love. He's smitten with Persephone, the goddess of grains, so he takes her to the underworld. In her absence, Earth's temperature plunges. When Persephone revisits the living world for six months of the year, spring and summer reportedly return.The OthersThere are other mythological deities. Athena is the goddess of wisdom. She sprang out of her father Zeus's head fully grown. Apollo is the god of the sun, who lights the world each day when he rides across the sky in a carriage drawn by fiery horses. There's Hermes, the god of speed and travel; Ares, the god of war; and Artemis, the goddess of the hunt. Many more oversee the world and turn it into their playground.Sure, they fall in and out of love, seek revenge, and rage over every problem. They plan ways to get what they want. But they also laugh and cry. They suffer and celebrate. If they were any more human, they wouldn't be deities at all.Maybe that's why Greek myths have lasted for thousands of years.
