Ok so the answer is sqrt of 39 but think about
Step-by-step explanation:
sqrt81 is 9 which is a whole number it is rational
sqrt16 is 4 which again is a whole number and is rational
1.9 is rational because it can be written as a fraction or ratio
but sqrt39 is a repeating decimal that goes on forever it still is a real number not fitting into the imaginary category but not a ration number.

Answers
Answer:
F. (-4, oo)
Step-by-step explanation:
Start from the left side.
The arrow on the left side shows that the graph continues increasing forever as x decreases. Beginning at the highest value of y you see on the left side at point (-6, 5), as x increases, moving right along the x-axis, the y-values decrease. When you get to x = -4, y is at its lowest value which is 1.
Starting just to the right of x = -4, the y-values begin to increase from the lowest y-value of 1. The arrowhead at the right side top shows that the curve continues increasing forever to infinity.
The values of x for which y increases are all values greater than -4 and all the way to positive infinity.
This function is increasing for x > -4.
Now we need to write x > -4 in interval notation.
In interval notation, use a curved parenthesis to mean a number that is not included. The interval starts at -4, so it starts as
(-4
Then you write a comma to separate from the value where the interval ends.
(-4,
The interval in x of increasing values goes to positive infinity, so now you write the infinity symbol, and you close the interval with a curved parenthesis. By convention, infinity always gets a curved parenthesis. Also, I'll use oo for infinity below.
(-4, oo)
Answer: F. (-4, oo)
Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease per unit of x, to the nearest tenth of a percent. Y 1600(1.46) Growth % increase Submit Anwar
Answers
Answer:
For any exponential function in which the base is less than 1, it will be an exponential decay situation. In this problem, the base is 0.97. The amount that the base is less than 1 ( i.e. 1 - base) represents, in decimal form, the percent of decrease, which in this case is 0.03 or 3%.
Step-by-step explanation:
The formula for exponential decay is y=a(1-r)x.
r is the decay rate.
A florist wants to determine if a new additive would extend the life of cut flowers longer than the original additive. The florist randomly selects 20 carnations from the ones recently delivered by the greenhouse and places the first 10 in water with the new additive and remaining 10 in water with the original additive. After three weeks, 6 carnations placed in the new additive still looked healthy and 2 carnations placed in the original additive still looked healthy. The proportion of healthy carnations with the new additive was significantly greater than the proportion of healthy carnations with the original additive.
Which of the following is a valid conclusion?
Conclusions about cause and effect for the additives can be made, because the florist randomly selected the 20 carnations; additionally, inferences can be made about the population of carnations at the greenhouse.
Conclusions about cause and effect for the additives cannot be made, because the florist did not randomly assign the 20 carnations; however, inferences can be made about the population of carnations at the greenhouse, because the sample was random.
Conclusions about cause and effect for the additives can be made, because the florist took a random sample of 20 carnations; however, inferences cannot be made about the population of carnations at the greenhouse, because the carnations were not randomly assigned to the treatments.

Tony runs to keep fit. He wants to run a total of 20 km each week. Here are the
distances Tony ran last week.
6.25 km
4 km 750 m
872 km
Did Tony run 20 km last week? You must show how you got your answer.
Answers
Answer:
Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.
Step-by-step explanation:
Distance Tony ran last week are
6.25 km
4 km 750 m
872 km (Note: This would be 8 [tex]\frac{1}{2}[/tex] km and not 872 km)
We will add all the distances to check if they sum up to 20km or not.
First we will convert 4 km 750 m into km
We know that 1000 m = 1 km
So, 1 m = 1/1000 km
750 m = 750/1000 = 0.75 km
Now 4km + 0.75 km = 4.75 km
So, 4 km 750 m = 4.75 km
and 8 [tex]\frac{1}{2}[/tex] km = 8.5 km
Now, finding Distance covered by Tony during last week = 6.25 km + 4.75 km + 8.5 km
= 19.5 km
So, Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.

Paige was planting a garden. She planted 1/3 of her garden with roses, 3/6 of her garden with daisies and the rest of the garden with tulips. What fraction of the garden was tulips?
Answers
Answer:
1/6
Step-by-step explanation:
Let the total number of flowers planted be 1
Given
Number of roses = 1/3
Fraction of daises = 3/6
Required
Fraction of tullips
Fraction of tullips = 1-(1/3+3/6)
Fraction of tullips = 1-(2+3/6)
Fraction of tullips = 1-5/6
Fraction of tullips = 1/6
Hence the fraction of tulip left is 1/6

An isosceles right triangle has a hypotenuse of length e. Select all that are true for the triangle.
Answers
Note: if the formulas don't load properly, then you may need to refresh the page.
======================================================
Explanation:
For any 45-45-90 right triangle, the hypotenuse H is always sqrt(2) times the leg L
In terms of symbols, we can say
[tex]H = L*\sqrt{2}[/tex]
We're told the hypotenuse is e, so H = e
Let's solve for L in terms of e
[tex]H = L*\sqrt{2}\\\\e = L*\sqrt{2}\\\\L*\sqrt{2} = e\\\\L = \frac{e}{\sqrt{2}}\\\\[/tex]
Now let's multiply top and bottom by [tex]\sqrt{2}[/tex] to rationalize the denominator
[tex]L = \frac{e}{\sqrt{2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{2}*\sqrt{2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{2*2}}\\\\L = \frac{e\sqrt{2}}{\sqrt{4}}\\\\L = \frac{e\sqrt{2}}{2}\\\\[/tex]
If the hypotenuse is e, then the length of each leg is [tex]\frac{e\sqrt{2}}{2}[/tex]
This matches with choice C, which is one of the two answers. This allows us to rule out choices A and B, as those expressions are not equivalent to the expression for choice C.
----------------
The two legs of any right triangle form the base and height. The order doesn't matter. The base is always perpendicular to the height. In a right triangle, the two legs are always perpendicular.
The base and height are [tex]\frac{e\sqrt{2}}{2}[/tex] each.
The area of the triangle is...
[tex]\text{Area} = \frac{1}{2}*\text{base}*\text{height}\\\\\text{Area} = \frac{1}{2}*\frac{e\sqrt{2}}{2}*\frac{e\sqrt{2}}{2}\\\\\text{Area} = \frac{e\sqrt{2}*e\sqrt{2}}{2*2*2}\\\\\text{Area} = \frac{e*e\sqrt{2*2}}{2*2*2}\\\\\text{Area} = \frac{e^2\sqrt{4}}{2*2*2}\\\\\text{Area} = \frac{e^2*2}{2*2*2}\\\\\text{Area} = \frac{e^2}{2*2}\\\\\text{Area} = \frac{e^2}{4}\\\\[/tex]
This matches with choice E, which is the other answer. Choices D and F are eliminated as they are not equivalent to the expression for choice E.
The required points that are correct are the length of the leg is given as e√2/2 and the area of the triangle is given as e²/4. Options D and E are correct.
Given that,
An isosceles right triangle has a hypotenuse of length e.
In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.
Here,
Let the measure of the leg be x,
Apply Pythagoras' theorem,
e² = x ² + x²
e² = 2x²
x = √e²/2
x = e/√2
or
x = e√2/2
Now,?
area of the triangle is given as,
area = 1/2 × e/√2 ×e/√2
area = e² / 4
Thus, the required points that are correct are the length of the leg is given as e√2/2 and the area of the triangle is given as e²/4. Options D and E are correct.

Using the graph below, find the value(s) of x for which f(x) = 5.
Answers
Answer:
We conclude that:
f(x) = 5 for x = -7, -6, -5, -4, -3, -2, -1, 0 and 2.
Step-by-step explanation:
From the diagram, it is clear that:
There are two parts of the graph:
LEFT GRAPHRIGHT GRAPHLEFT GRAPH
On the left side, the graph of the function indicates that the value of y remains 5 for the values x = -7, -6, -5, -4, -3, -2, -1, and 0.
In other words,
f(x) = 5, for x = -7, -6, -5, -4, -3, -2, -1, and 0.
RIGHT GRAPH
On the right side, the graph of the function indicates that the value of y is 5 at x = 2
In other words,
f(x) = 5, for x = 2.
Therefore, we conclude that:
f(x) = 5 for x = -7, -6, -5, -4, -3, -2, -1, 0 and 2.

At the end of 2005, this price was `\$513.` At the end of 2015, it was `\$1060.` By what percentage did the price per ounce of gold increase?
Answers
Answer: The price per ounce of gold increases by 106.63%.
Step-by-step explanation:
Given: Price in 2005 = $ 513
Price in 2015 - $ 1060
Now , [tex]\text{Percentage increase in price}=\dfrac{\text{Change in price}}{\text{ Initial price}}\times100[/tex]
[tex]\Rightarrow\ \text{Percentage increase in price}=\dfrac{1060-513}{513}\times100\\\\=\dfrac{547}{513}\times100\\\\= 1.0663\times100\%=106.63\%[/tex]
hence, the price per ounce of gold increases by 106.63%.
