Add and write in standard form: (-3x^4 + 6x^3 - 43) + (8x^5 - x^2 + 12x + 10)
A.) 8x^5 - 3x^4 + 6x^3 - x^2 + 12x - 33
B.) x^5 - 5x^3 + 12 - 33
C.) -33 + 12x - x^2 + 6x^3 - 3x^4 + 8x^5
D.) -13x^14
Answer:
A.) 8x^5 - 3x^4 + 6x^3 - x^2 + 12x - 33
Answer: A
Step-by-step explanation:
Because the only thing that can be combined is - 43 and 10, you just need to combine that and write everything else out.
- 43 + 10 = - 33
Now just write everything out...
8x^5 - 3x^4 + 6x^3 - x^2 + 12x - 33
Which is A
Examine the table, which represents a linear function.
What is the rate of change of the function?
Input (x) Output (y)
-5 18
−3 23
−1 28
1 33
Answer:
I believe it should be 3 23
Answer:
2.5
Step-by-step explanation:
The rate of change can be found from the slope formula.
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find ...
m = (23 -18)/(-3 -(-5)) = 5/2
The rate of change of the function is 5/2 = 2.5.
What percentage of a dollar is the value of 5 quarters and 1 dime?

the answer would be eight
Step-by-step explanation: it would hit the first 90 degree angle when the hour is at twelve and the minutes at 15 then 12 and 45 then 3 and 30 and three and 12 then 6 and 15 and six and 30 then 9 and 30 then 9 and 12 .
1, 1, 2, 3, 5, 8 are the first six numbers of the fibonacci sequence. what is the eighth number?
Answer:
21
Step-by-step explanation:
1, 1, 2, 3, 5, 8, 13, 21
The required eighth number in the Fibonacci sequence is 21.
Given that,
1, 1, 2, 3, 5, and 8 are the first six numbers of the Fibonacci sequence. what is the eighth number is to be determined
The sequence is defined as the specific pattern of numbers in which they are arranged.
Here,
given Fibonacci sequence is 1, 1, 2, 3, 5, 8
The Fibonacci numbers, sometimes known as Fn, are a set of numbers in mathematics where each number is the sum of the two numbers before it.
According to the above definition,
7 th number = 5th number + 6th number =
7 th number = 5 + 8 = 13
8th number = 8 + 13 = 21
Thus, the required eighth number in the Fibonacci sequence is 21.

Answer:
[tex] \frac{88}{4} \\ 22 \\ here \: u \: go[/tex]
Answer:
22 cm
Step-by-step explanation:
The angle subtended at the centre by the arc is 90°
This represents [tex]\frac{90}{360}[/tex] = [tex]\frac{1}{4}[/tex] of the circle
The arc length will be quarter of the circumference, that is
arc = [tex]\frac{1}{4}[/tex] × 88 = 22 cm
The farmer bought 2.5 sacks of fertilizer for $2.20 per sack and 4.5 sacks of essential soil for $1.80 for each sack from the supplier. If he gave a $15 bill to the supplier, how much would his change be?
Answer:
$0.50 or 50 cents
Step-by-step explanation:
If he bought 2 and a half sacks of fertilizer for $2.20 that means u multiply 2.20 2 and a half times so first lets divide 2.20 by 2 to find the solution of the "0.5" which is 1.10
2.20 times 2 equals 4.40 then we add the 1.10 so 4.40 plus 1.10 is $5.50.
For the 4.5 sacks of 1.80 we will do the same technique half o 1.80 is 90 cents so 0.90 and 4.5 times 1.80 is $8.10 we then add the 90 cents making it $9.
We then add the 2 totals of $9 and $5.50 which equals $14.50, the change would be 50 cents which in decimal form would be $0.50

$61.60 for parts and labor rate is $30.00 per hour total cost 136.60 how many hours will the job take? Write an equation and explain how you used it to find the number of hours the job will take.
Answer:
(136.60 - 61.60) / 30 = 2.5 hours
Step-by-step explanation:
First, subtract the cost of parts from the total: 136.60 - 61.60 = 75
Now you have the total labor cost. Divide by the hourly rate: 75 / 30 = 2.5

Which of the following lists of ordered pairs is a function?
A. (3, –2), (2, –1), (3, 4), (4, 7)
B. (0, 4), (1, 2), (1, 0), (2, 3)
C. (2, 5), (3, 8), (4, 11), (4, 12)
D. (1, 7), (2, 5), (3, 6), (4, 1)
Answer:
D
Step-by-step explanation:
In this case, we can define a function as a "relation and the set of ordered pairs that doesn't contain 2 pairs with matching components"
In A above, (3,-2), (2,-1), (3,4), (4,7)
There is a repeat of 3 in both (3, -2) and (3,4) so this can't be considered a function.
B. (0, 4), (1, 2), (1, 0), (2, 3)
There is a repeat of 1 in both (1, 2) and (1, 0), so this is not a function.
C. (2, 5), (3, 8), (4, 11), (4, 12)
4 is repeated in (4, 11) and (4, 12) so this cancel out its probability of it being a function.
D. (1, 7), (2, 5), (3, 6), (4, 1)
D. (1, 7), (2, 5), (3, 6), (4, 1)There is no repeat of components, so this is considered a function.

The number of comic books is an illustration of a linear function
The complete equations are: [tex]\mathbf{8b + 17 =65}[/tex] and [tex]\mathbf{b =6}[/tex]The value of b has increased by 4She had 17 comic books already.
So, we have:
[tex]\mathbf{Base\ Amount = 17}[/tex]
Her order of 65 books contains 8 comic books per collection.
So, we have:
[tex]\mathbf{Rate = 8}[/tex]
[tex]\mathbf{Total = 65}[/tex]
This is represented as:
[tex]\mathbf{Rate \times b + Base\ Amount =Total}[/tex]
So, we have:
[tex]\mathbf{8\times b + 17 =65}[/tex]
Rewrite as:
[tex]\mathbf{8b + 17 =65}[/tex]
Subtract 17 from both sides
[tex]\mathbf{8b =48}[/tex]
Divide both sides by 8
[tex]\mathbf{b =6}[/tex]
Assume she has 97 books in her collection, then the equation would be represented as:
[tex]\mathbf{8b + 17 = 97}[/tex]
Subtract 17 from both sides
[tex]\mathbf{8b = 80}[/tex]
Divide both sides by 8
[tex]\mathbf{b = 10}[/tex]
The values of b are 6 and 10.
The difference between 6 and 10 is 4
Hence, the value of b has increased by 4

Jada measured the height of a plant in a science experiment and finds that, to the nearest 1/4 of an inch, it is 4 3/4 inches.
What is the largest the actual height of the plant could be?
4 7/10
inches
Answer:
Step-by-step explanation:
Given that the height(h) of the plant to the nearest 1/4 of an inch is 3/4 inches = 0.75 inches.
It is obvious that the height will lie within the range
2.5/4<h<3.5/4
which corresponds to the range
5/8<h<7/8 OR 0.625<h<0.875
Thus,
a. The largest actual height could be 0.875 inches, while
b. The smallest actual height could be 0.625 inches
c. The percentage error is given by the formula:
[(approx.-exact)/exact]*100%
If we take the lowest value, for instance, as the exact, i.e. 0.625 inches,
then % error = [(0.75-0.625)/0.75]*100% = 16.7%
Obviously, the same value is expected if we take the upper limit of 0.875, i.e. % error = [(0.75-0.875)/0.75]*100% = -16.7%, only that the absolute value will be taken.

What is an equation of the line perpendicular to y=1/5x+2
That contains (15, -4)?
PLS HELP
Answer:
y+4=-5(x-15)
Step-by-step explanation:
Use point-slope form:
y-y1=m(x-x1)
m is the slope
x1 is the x coordinate of the point that the line contains
y1 is the y coordinate of the same point
We are already given the coordinates of the point (15, -4), so we just need m, the slope.
We are given that equation of the line is perpendicular to line y=1/5x+2. Perpendicular lines have slopes that are negative reciprocals of one another. The slope of y=1/5x+2 is 1/5, so all we need to do it get the negative reciprocal of 1/5.
The negative reciprocal of 1/5 would be -5. (switch the numerator and denominator and slap on a negative)
Now we know
m is -5
x1 is 15
y1 is -4,
so plug those into point-slope form: y-y1=m(x-x1)
y-(-4)=-5(x-15)
y+4=-5(x-15) is the answer
