b. Triangle ABC is similar to triangle EBD. Find the lengths of segments BD and BE. Show all your work.

Answers

Answer 1

Answer:

BD=4/3 BE=5/3

Step-by-step explanation:

by pythag theorem we can see that AC=3 and because CPCTC

AC/DE=AB/EB=CB/DB we can see that CB/DB=3/1 and CB is 4 therefore DB = 4/3 do same with BE and we get solution above.

Step-by-step explanation:

The only terms that can be combined are the constants.

(f -g)(x) = f(x) -g(x)

(f -g)(x) = (-5^x -4) -(-3x -2) = -5^x -4 +3x +2

(f -g)(x) = -5x^4 +3x -2 . . . . . matches A

Sarah works for a maximum of 40 hours per week. She needs to make at least $400 in order to cover her expenses. Her office job pays
$12 per hour and her babysitting job pays $10 per hour.
Which system of inequalities can be used to determine the number of hours she should spend working in office (x) and the number of
hours she should spend babysitting (/) to cover her expenses?

Answers

Answer:

x + y ≤ 40

10x + 12 y ≥ 400

x ≥ 0

y ≥ 0

Step-by-step explanation:

System of Inequalities

In order to model the situation stated in the problem, we'll call the following variables:

x = number of hours Sarah spends in the office

y = number of hours Sarah spends babysitting

She works for a maximum of 40 hours per week. This condition leads us to the inequality:

x + y ≤ 40

Her office job pays $12 per hour and her babysitting job pays $10 per hour.

She needs to make at least $400 per week in order to cover her expenses, thus:

10x + 12 y ≥ 400

Two obvious conditions could be added to the set of inequalities:

x ≥ 0

y ≥ 0

The system of inequalities is:

x + y ≤ 40

10x + 12 y ≥ 400

x ≥ 0

y ≥ 0

A person runs at 35 m/s from a standstill. What is their acceleration after 5 sec?

Answers

Answer:

The acceleration is 7m/s^2

Step-by-step explanation:

Given

[tex]u = 0m/s[/tex] -- Initial Velocity

It is 0 because the person starts from a standstill

[tex]v = 35m/s[/tex] -- final velocity

[tex]t = 5s[/tex] -- time

Required

Determine the acceleration

This is calculated using Newton's first equation of motion

[tex]v = u + at[/tex]

Substitute values for v, u and t

[tex]35 = 0 + a*5[/tex]

[tex]35 = 0 + 5a[/tex]

[tex]35 = 5a[/tex]

Divide both sides by 5

[tex]\frac{35}{5} = a[/tex]

[tex]7 = a[/tex]

[tex]a = 7[/tex]

Hence, the acceleration is 7m/s^2

The answer : 4x^2 + 28x + 48

The value of the equation is A = 4x² + 28x + 48

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = ( 2x + 6 ) ( 2x + 8 ) be equation (1)

Now , on simplifying the equation , we get

A = 2x ( 2x + 8 ) + 6 ( 2x + 8 )

On further simplification , we get

A = 2x ( 2x ) + 2x ( 8 ) + 6 ( 2x ) + 6 ( 8 )

A = 4x² + 16x + 12x + 48

A = 4x² + 28x + 48

Therefore , the value of A is 4x² + 28x + 48

Hence , the equation is A = 4x² + 28x + 48

Use a number line to find the quotient 3/4 divided by 1/8

Answers

Answer:

Step-by-step explanation:

The required quotient of 3/4 divided by 1/8 on the number line is 6.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

As mentioned in the question, it is to be determined quotient when a fraction is 3/4 divided by the number 1/8.
When the 3/4 is simply divided by 1/8 we get,
= 3/4 / [1/8]
= 6

On a number line, the given expression shows the addition of the given fraction for the 8 times by itself as,
= 3/4 = 0.75

Now,
on a number line,
= 0.75 + 0.75 + 0.75 + 0.75 + 0.75 + 0.75 + 0.75 + 0.75
= 6

Thus, on the number line, the quotient 3/4 divided by 1/8 is 6.

Today a lake in Minnesota is named Sourdough Lake.A Giant of a ManA big burly man dressed as a lumberjack stands next to a big ox and holds an ax over his shoulder.Back in 1913, I worked on one of Paul Bunyans famous crews. Let me tell you, there are many good tales about the legendary Paul Bunyan, but they dont tell half the story. He was a giant of a man who could pick up four horses with their load of logs and turn them around on the road. He led crews of us loggers to hew trees and chop them into logs during the days when this country was growing fast.Feeding Bunyans crews of ravenous loggers was a big job. Pauls cook Big Joe wanted a griddle to cook pancakes. So, Big Ole, the blacksmith, made an immense griddle. The pancake batter was stirred in machines like concrete mixers. It was poured on the griddle with cranes.One year, everything got buried during the Winter of the Deep Snow. It was quite a predicament. Paul dealt with the challenge by digging down to find the tops of the tall pine trees and lowering his loggers to chop logs. His blue ox, Babe, wore snowshoes to haul the wood to the surface of the snow.Paul had a cow named Lucy. She had the appetite of a wolf. In the winter of the Deep Snow, the loggers gave Lucy a pair of Babes old snowshoes and green goggles. They turned her out to graze in the snow. She learned to run in the snowshoes, and she ran all over North America.One of Pauls loggers took a load of logs down the Mississippi River for Paul. When the logs were delivered, they were the wrong logs. Paul had to get them back upstream. Driving logs upstream is impossible, but an impossible job never stopped Paul. He fed Babe salt and took him to the upper Mississippi to drink. Babe drank the river dry, and the logs traveled up the river faster than they had gone down.Paul could solve problems like no one else I ever knew or you ever heard of. In the Winter of the Blue Snow, Shot Gunderson was in charge of the Big Tadpole River area. He chopped his logs so that they landed in a lake. He planned to move them in the spring. To his surprise, when he tried to move the logs, he discovered the lake had no outlet to the river. He thought the whole winters work was lost. But Paul was always clever. He came up with an ingenious idea. He called in Sourdough Sam, a cook who made everything out of sourdough except the coffee. Paul ordered him to mix enough sourdough to fill the big water tank. Then he hitched Babe the Blue Ox to the tank and dumped the sourdough into the lake. Dough rises. As Sam said, it riz and pushed the logs over the hills that surrounded the lake. They rolled all the way to the river. Today a lake in Minnesota is named Sourdough Lake. These colonist wanted to remain loyal to Britain.1. patriots2. loyalists3. neutralists4. separatistsWhich one?
