Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5
f(x) = x + 9, g(x) = x2 − 4x, h(x) = x4 + 2x3
What is the degree of (f º g º h)(x)?

Answer:
the degree of the function is 8
Step-by-step explanation:
(f º g º h)(x) = [tex]f(g(h(x)))[/tex]
first lets evaluate g(h(x))
[tex](x^4 + 2x^3)^2 - 4(x^2 + 2x^3)[/tex]
simplify
[tex]x^8 + 4x^3 + 4x^6 - 4x^4 -8x^3[/tex]
[tex]x^8 + -4x^3 + 4x^6 - 4x^4[/tex]
you can easily see that the highest power term is 8 meaning the degree of the function is 8
Answer:
its 8 :)

Jana uses 20 cards to play a memory game the cards are either animal cards or fruit cards. The ratio of animal cards to fruit cards is 2:3 How many if the 20 cards are animal cards? Of the fruit cards, 1/3 have bananas on them. How many cards have bananas on them. Show or explain your work.
Given that,
Total no of cards = 20
The ratio of animal cards to fruit cards is 2:3
No of animal cards = 20
Solution,
Let there are 2x animal cards and 3x fruit cards. ATQ,
2x+3x = 20
5x = 20
x = 4
Animal cards = 2x
= 2(4)
= 8
Fruit cards = 3x
= 3(4)
= 12
It is also mentioned that, of the cards, 1/3 have bananas on them. It means,
[tex]B=\dfrac{1}{3}\times 12\\\\=4[/tex]
Hence, 4 cards have bananas on them.
The domain on which the following function is increasing
The domain on which of the following function is increasing is [0,4].
Given:
The graph of a function.
To find:
The domain on which of the following function is increasing.
Domain is the set of x-values or input values.
From the given graph it is clear that the vertex of the given function is at (4,75).
Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.
The function is defined for 0≤x≤9 .
Since the graph is increasing when 0≤x≤4 , therefore the function is increasing over the interval [0,4].
Therefore, the domain on which of the following function is increasing is [0,4].
What is domain?
The domain is the value that x can take from a given function and codomain is the value of y from a function.

Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1

Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.

Which number can each term of the equation be multiplied by to eliminate the decimals before solving?
–m + 0.02 + 2.1m = –1.45 – 4.81m
0.01
Answer:
Multiply by 100
Step-by-step explanation:
The equation is given as:
-m + 0.02 + 2.1m = -1.45 - 4.81m
To eliminate the decimals from all the terms, we must multiply by a number that make all the coefficients integers.
The decimal coefficients and independent terms are
0.02, 2.1, 1.45, 4.81
Note the maximum number of decimals found in all of them is 2. Thus, multiplying by 100 all the decimals will vanish as follows:
100(-m + 0.02 + 2.1m) = 100(-1.45 - 4.81m)
-100m + 2 + 210m = -145 - 481m
Now all terms have integer coefficients as required.
Answer: Multiply by 100

what is (5.91 x 10^-3) - (8.7 x 10^10) written in a scientific notation? Please answer asap thank you :))
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]\left(5.91\times \:10^{-3}\right)-\left(8.7\times \:10^{10}\right)[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]
[tex]=5.91\times \:10^{-3}-8.7\times \:10^{10}[/tex]
as
[tex]5.91\times \:10^{-3}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=5.91\times \frac{1}{10^3}[/tex]
[tex]=\frac{5.91}{1000}[/tex]
[tex]=0.00591[/tex]
similarly
[tex]8.7\times \:10^{10}[/tex]
Convert element to a decimal form
[tex]10^{10}=10000000000[/tex]
so
[tex]=10000000000\times \:8.7[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:8.7\times \:10000000000=87000000000[/tex]
[tex]=87000000000[/tex]
Thus, the expression becomes
[tex]\left(5.91\times \:\:10^{-3}\right)-\left(8.7\times \:\:10^{10}\right)=5.91\times \:\:10^{-3}-8.7\times \:\:10^{10}[/tex]
[tex]=0.00591-87000000000[/tex]
[tex]=-86999999999.9941[/tex]
Hence,
converting -86999999999.9941 in a scientific notation
In order to make our job easier we will remove the sign "-" from number -86999999999.9941 (we will write "-" at the final solution). So after this step we have:
−86999999999.9941 ⟶ 86999999999.9941
In order to write number 86999999999.9941 in scientific notation, we need to move the decimal point from its current location (black dot) to the new position such as:
8.6999999999.9941
So, we need to move the decimal point 10 places to the right.
This means that the power of 10 will be positive 10.
Now we have that the
Number part = 8.69999999999941 and
Exponent part = 10
Thus, we conclude that:
−86999999999.9941 = − 8.69999999999941 × 10¹⁰

Answer:

Step-by-step explanation:
9v
The polynomial function for the volume V of the tray in terms of x will be;
⇒ 4x³ - 30x² + 54x
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
Lucy cuts 4 squares with side length x inch from the corners of a 6 inch by 9 inch cardboard rectangle.
She folds the remaining cardboard to make a tray that is x inch high
Now,
By the give condition we get;
Length of tray = 9 - 2x
Width of tray = 6 - 2x
Height of tray = x
So., The volume of the tray is expressed as;
Volume = x (9 - 2x) (6 - 2x)
= x (54 - 18x - 12x + 4x²)
= x (54 - 30x + 4x²)
= 4x³ - 30x² + 54x
Thus, The polynomial function for the volume V of the tray in terms of x will be;
⇒ 4x³ - 30x² + 54x
