Which function describes this table of values? х у 10 8 5 4 0 0 -5 -4 y = 2 y= y = x - 2 y=-3

Answers

Answer:

y=4/5x

Step-by-step explanation:

If you multiply the x value of 10, substitute it into the equation. Using the equation y=4/5x, you will get the y value of 8.

When you substitute the x value of 5 into the equation. You will get 4.

You do this for the rest of the x values and will get the correct y values.

x+0.5y=1.5 solve for y

It took a car 4 days to travel 2686 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)

Answers

Answer:

28

Step-by-step explanation:

Well we know that in a day there are 24 hrs so in 4 days there will be 96 hrs

so the car travelled 2686 miles in 96 hours

2686/96= 27.9791666667

So the car's average speed is about 28

5. A joint of meat weighs 3.5 kg when frozen. It loses 8% of its weight
when it is thawed. Find the mass of the joint when thawed. *​

Answers

Answer:

The mass of the meat when thawed is 7.72 kg (0.28 kg is lost)

Step-by-step explanation:

From the question, we are told that the weight loss amount is 8% of its initial weight

The mass lost here when thawed will be;

8/100 * 3.5 = 0.28 kg

So the mass of the joint will be;

8-0.28 = 7.72 kg

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground, the ladder is turned to across the street to reach a window that was 40 feet high.

Select all the true statements.

The width of the street, BM, is 70 feet.
The ground distance of the ladder from building B is 30 feet.
The ground distance of the ladder from building M is 30 feet.
The width of the street, BM, is 122 feet.
The length KL is 50 feet.

Answers

Answer:

First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40    Line BL = 40 ft

Since the ladder is 50 feet it is the same length on the other side as well

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        line LM is 30 ft

SO line lm + line bl = 30 + 40 = 70 ft

A is true because ^

B isn't true because as we solved for earlier, BL is 40

C is true because line LM is in fact 30 ft as we solved for

D is not true because as we said earlier BM is 70

E is true because the same ladder was used on both sides of the street

Step-by-step explanation:

The width of the street, BM, is 70 feet. The ground distance of the ladder from building M is 30 feet. The length of KL is 50 feet.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

First, because two of the possibilities require the width of BM, let us solve for it using the Pythagorean theorem for both sides of point L.:

a² + b² = c²

30² + b² = 50²

b² = 50² - 30²

b² = 1600

b = 40  

So, Line BL = 40 ft

So because the ladder is 50 feet long, it is also the same length on the other side.

a² + b² = c²

40² + b² = 50²

b² = 50² - 40²

b² = 900

b = 30        

So, line LM is 30 ft

So line lm + line bl = 30 + 40 = 70 ft

Hence, the true statements are options (A), (C), and (E).

Find an equation for y in terms of x

Answers

Answer:

y = [tex]\frac{9}{x^2}[/tex]

Step-by-step explanation:

Given y is inversely proportional to x² then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion

To find k use an ordered pair from the table

Using x = 3 when y = 1 , then

1 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )

9 = k

y = [tex]\frac{9}{x^2}[/tex] ← equation of proportion

Created for the purpose of policing broader frauds against the government, the Secret Service originally focused on counterfeiting. The Secret Service also investigated smugglers, individuals perpetrating land or real-estate fraud, distillers of illegal liquor, and the Ku Klux Klan. In 1894, the protective duties of the Secret Service began informally with agents providing part-time protection to President Grover Cleveland. Following the assassination of President William McKinley, Congress informally requested presidential security service. In 1902, the Secret Service assumed full time responsibility for protecting the president and his family. In 1908, this protection was also extended to the president-elect. In 1913, Congress authorized permanent protection of the president. Following the assassination of President John F.
