PLZ HELP only got 30 minutes left will brainliest. What is the rate of change of the function? –2 --1/2 1/2 2

Answer:

1=x

Step-by-step explanation:

The equation would be 2=3-√x *x

subtract 3 from both sides

-1=-√x *x

multiply x*x

-1=-√x^2

the square and the square root cancel each other out

-1=-x

1=x

Now to check the answer works.

2=3-√1*1

2=3-√1

2=3-1

2=2

Answer:

-25.6

Answer:

Vertical lines are not functions.(not functions )

Function with no arguments and no return value.

Function with no arguments and a return value.

Function with arguments and no return value.

Function with arguments and a return value.

Step-by-step explanation:

The equations y = ± x and x 2 + y 2 = 9 are examples of non-functions because there is at least one -value with two or more -values. The vertical line test is a great way to visualize a violation of the definition of a function.

Answer: the curved one is not a function because it is curved.

Step-by-step explanation:

Answer:

A:

[tex]5^3*5^{-4}=5^{3-4}=5^{-1}=\frac{1}{5}[/tex] (It is a value between 0 and 1.)

B:

[tex]\frac{3^5}{3^{-6}}=3^{5-\left(-6\right)}=3^{5+6}=3^{11}=177147[/tex] (It is not a value between 0 and 1.)

C:

[tex]\left(\frac{1}{4}\right)^3\cdot \left(\frac{1}{4}\right)^2=\left(\frac{1}{4}\right)^{3+2}=\left(\frac{1}{4}\right)^5=\frac{1^5}{4^5}=\frac{1}{1024}[/tex] (It is a value between 0 and 1.)

D:

[tex]\frac{\left(-7\right)^5}{\left(-7\right)^7}=\left(-7\right)^{5-7}=\left(-7\right)^{-2}=\frac{1}{\left(-7\right)^2}=\frac{1}{49}[/tex] (It is a value between 0 and 1.)

Answer:

To convert scientific notation to standard form you would need to move the decimal point over the number of the places that the exponent indicates. If the exponent is negative you move the decimal to the left, and if the exponent is positive you move the decimal to the right.

Step-by-step explanation:

1.456*10^3 would be scientific notation.

The exponent is a positive 3, means that you move the decimal 3 places to the right.

1456 would be the standard form.

1.456*10^-3 would be scientific notation.

The exponent is a negative 3, means that you move the decimal 3 places to the left.

0.001456 would be the standard form.

Answer:

Step-by-step explanation:

For part a, take all the data ( in your case line up the flower's height in inches) and find the mean. To do this you add all of the numbers together and divide by the number of numbers (EXA: 13,4,12,7---> 13+4+12+7= 36---> 36/4=9; 9 is the mean)

For part b, do the same thing, except use the values for the vegitable heights.

For part c, it's asking you to compare the values, (find their differences) and figure out the variability, which means to find the pattern in growth between both the flowers and vegitables, and explian them.

I hope this helps! :)

Answer:

  division of 16 by 3.2

Step-by-step explanation:

  2.5(4^2 ÷ 3.2 – 10(0.2) + 3)– 5.2

  2.5(16 ÷ 3.2 – 10(0.2) + 3) – 5.2

Next, he will perform multiplication and division inside parentheses, left to right.

  2.5(5 – 10(0.2) + 3) – 5.2 . . . . . Bryan's next step

  2.5(5 – 2 + 3) – 5.2

Then, he will finish evaluating inside parentheses by performing addition and subtraction left to right.

  2.5(3 + 3) – 5.2

  2.5(6) – 5.2

With parentheses evaluated, now we do multiplication and division, left to right.

  15 – 5.2

Finally, addition and subtraction left to right.

Answer:

30-21.48=8.52

due to the laws of subtraction in math,

the result of the equation we have formulated is

8.52

8.52 miles is the answer

The difference between second week hike to first weekend is 8.52 miles.

What is difference?

The difference is the operational name of subtraction in math which can be obtained by subtracting a smaller number from a greater number. The number we subtract from is called minuend. The number being subtracted is called subtrahend while the result is called ‘difference’.

Given,

Robert hiked on first weekend = 21.48

On second weekend he hiked = 30 miles

The greater value is 30 miles, achieved by him in second weekend

Therefore, 30 - 21.48 = 8.52

The difference is 8.52 miles.
