A 20 foot ladder is set against the side of a house so that it reaches up 16 feet. If Christian grabs the ladder at its base and pulls it 2 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 14 ft.) Round to the nearest tenth of a foot.
Answer:
14.2
Step-by-step explanation:
The ladder forms a right angles triangle,
We have,
h=20
p=16
b=x
Using pythogorean theorem,
b=√(20^2-16^2)
√144
b=12
Now,
Since, she pulls it 2 cm,
b=x+2
b=14
p=?
Using pythogorean theorem,
p=√(20^2-14^2)
√204
p=14.2828568571
Rounding to the nearest tenth,
p=14.2
The side of the ladder will reach up is 14.3 feet.
What is trigonometric Ratios?"Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. It is with respect to any of its acute angles are known as the trigonometric ratios of that particular angle".
For the given situation,
Hypotenuse, h = 20 feet
Perpendicular, p = 16 feet
Base = b
By Pythagoras theorem,
[tex]h^{2} = p^{2} + b^{2}[/tex]
⇒[tex]20^{2} = 16^{2}+b^{2}[/tex]
⇒[tex]b^{2} = 400-256[/tex]
⇒[tex]b^{2}=144[/tex]
⇒[tex]b=\sqrt{144}[/tex]
⇒[tex]b=12[/tex]
The ladder at the house is pulled 2 feet farther.
So, base = [tex]12+2[/tex]
⇒[tex]b=14[/tex]
Now, the side of the ladder will reach up
[tex]p^{2} = h^{2}-b^{2} \\[/tex]
⇒[tex]p^{2}=20^{2}-14^{2} \\[/tex]
⇒[tex]p^{2}=400-196[/tex]
⇒[tex]p^{2}=204[/tex]
⇒[tex]p=\sqrt{204}[/tex]
⇒[tex]p=14.28[/tex]
⇒[tex]p=14.3[/tex] (rounded off to nearest tenth)
Hence we can conclude that the side of the ladder will reach up is 14.3 feet.

For any nonnegative real number.
Answer:
A
Step-by-step explanation:
We know that [tex]\sqrt{b}=b^{1/2}[/tex].
We also know that [tex](a^b)^c=a^{bc}[/tex].
We can combine these facts to get [tex](\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b[/tex].
So, the answer is [tex]\boxed{A}[/tex] and we're done!
Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.

x → ∞ y → ∞ and as x →- ∞ y → -∞ is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The meaning of end behavior is how the function ‘y’ (in this case) moves when x tends towards both ∞ and - ∞.
As x → ∞ y → ∞.
This is apparent from the upward movement of the graph of the function y=10x⁹ –4x
As x →- ∞ y → -∞
This inference is also drawn from the above graph i.e. as x values become more negative the graph of y also travels towards infinity i.e. southward on the LHS of the above graph.
Even though the graph of the function remains flat in between x = -4 to x = 4.
After these points, the graph moves towards infinity exponentially.
Hence, x → ∞ y → ∞ and as x →- ∞ y → -∞ is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x

Find the mean rounded to the nearest tenth median mode and range 59,50,54,50,50
Answer:
Mean = 52.6
Median = 50
Mode = 50
Range = 9
Step-by-step explanation:
How to find the mean
The mean of a set of numbers is the sum divided by the number of terms.You add 59,50,54,50,50 then divide it by 5 because there are 5 numbersHow to find the median
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.How to find the mode
The mode is the element that occurs most in the data set. In this case, 50 occurs 3 times.How to find the range
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 59 − 50 = 9Hope this helps

Write the sum of 7divided by 7x^6+ 4 dividend by 7x^6 in simplest form, if x = 0
Answer:
0
Step-by-step explanation:
The equation if I read this correctly is:
(7 / 7x⁶+4) / 7x⁶
Using x = 0 you would have:
[7 / (7(0)⁶+4)] / 7(0)⁶
(7 / 0 +4) / 0
(7/4) / 0 which is the same as 7/4 x 0 = 0
