If y is directly proportional with x and y=24 when x=6. What is the value of x when y=16

Answers

Answer:

x = 4

Step-by-step explanation:

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 24 when x = 6 , then

24 = 6k ( divide both sides by 6 )

4 = k

y = 4x ← equation of proportion

When y = 16, then

16 = 4x ( divide both sides by 4 )

4 = x

A tree initially measured 18 feet tall. Over the next 312 years, it grew to a final height of 3512 feet. During those 312 years, what was the average yearly growth rate of the height of the tree?

Answers

Answer:

Average growth= 11.20 feet

Step-by-step explanation:

First, we need to calculate the total growth during those 312 years:

Total growth= 3,512 - 18

Total growth= 3,494 feet

Now, the average growth:

Average growth= total growth / number of years

Average growth= 3,494 / 312

Average growth= 11.20 feet

help! this is algebra 1 and idk how to do it lol

Answers

Answer:

a. x+6 = 0

b. y-2 = 0

Step-by-step explanation:

Given point is:

(-6,2)

a. Line perpendicular to x-axis:

A line perpendicular to x-axis means that the line is vertical and parallel to y-axis. Any equation parallel to y-axis has the form

x = k

where k is the x-coordinate of the point from which the line passes.

So the required equation is:

[tex]x = -6\\x+6 = 0[/tex]

b. Line perpendicular to y-axis:

A line perpendicular to y-axis will be a horizontal line parallel to x-axis having the equation of the form

y = b

where b is the y-intercept

Required equation is:

[tex]y = 2\\y-2=0[/tex]

Hence,

a. x+6 = 0

b. y-2 = 0

Find the limit !!!!!!

Answers

Answer:

1/8.

Step-by-step explanation:

Use l'Hopitals rule - we find the derivative of top and bottom of the fraction.

Derivative of the numerator = 0 - 1/2 (16 - x)^-1/2 -1

= 1 / [ 2 * (16 - x)^1/2

Derivative of the denominator = 1

When x approaches 0 this is 1 / (2*4)

= 1/8.

Another way to do this is to multiply top and bottom by 4 + (16 - x)^1/2

This becomes 16 - (16 - x) / x(4 + (16-x)^1/2)

= 1 / (4 + (16 + x)^1/2

When x ---> 0

this = 1 /(4 + 4)

= 1/8.

Monday's high temperature in Denver, Colorado was 25°F. The low temperature was
-4° F. What was the difference between the high and low temperatures?

Answers

Answer:

The difference between the high and low temperatures is 29°F

Step-by-step explanation:

Subtraction

The high temperature in Denver, Colorado was 25°F on Monday.

The low temperature was -4°F in the same place.

We are required to find the difference between the high and low temperatures.

We need to subtract 25 and -4:

Difference = 25°F - (-4°F)

Note we change the sign of the subtraction multiplying (-1) by (-1);

Difference = 25°F + 4°F

Difference = 29°F

The difference between the high and low temperatures is 29°F

Explain why 20 is not a square number.

Answers

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 20 is about 4.472. Thus, the square root of 20 is not an integer, and therefore 20 is not a square number.

The reason why 20 is not a square number is because it's square root is not an integer.

Why is 20 not a square number?

It follows from the task content that we explain why 20 is not a square number.

First, a square number is one whose square root is an integer. Hence, such a number is a perfect square.

On this note, 20 is not a square number because it's square root is not an integer.

Federal protection of bank deposits ended the dangerous trend of bank runs. Abuse of the stock market was more clearly defined and monitored to prevent collapses in the future. The Social Security system was modified and expanded to remain one of the most popular government programs for the remainder of the century. For the first time in peacetime history the federal government assumed responsibility for managing the economy. The legacy of social welfare programs for the destitute and underprivileged would ring through the remainder of the 1900s.Laborers benefited from protections as witnessed by the emergence of a new powerful union, the CONGRESS OF INDUSTRIAL ORGANIZATIONS. African Americans and women received limited advances by the legislative programs, but FDR was not fully committed to either civil or women's rights.

He starts by referring to Franklin Roosevelt's New Deal.Franklin Roosevelt's rapid conversion from Constitutionalism to the doctrine of unlimited government is an oft-told story . . . I am here concerned . . . by the unmistakable tendency of the Republican Party to adopt the same course. The result is that today neither of our two parties maintains a meaningful commitment to the principle of States' Rights. Thus, the cornerstone of the Republic, our chief bulwark against the encroachment of individual freedom by Big Government, is fast disappearing under the piling sands of absolutism. . .
