PLEASE HELP WILL GIVE BRAINLIEST. Which of the following describes the function –x4 + 1?
Answer:
The correct answer is-
b. The degree of the function is even, so the ends of the graph continue in the same direction. Because the leading coefficient is negative, the left side of the graph continues down the coordinate plane and the right side also continues downward.

Steve types at a rate of 45 words per minute. He writes an equation relating the number of words he can type, w, to the number of minutes he spends typing, m. w = 45m Xena doesn’t know the number of words per minute that she can type. But she recorded the time it took her to type different numbers of words in this table.
minutes words
02 100
04 200
08 400
Answer:
50 words per minute
Step-by-step explanation:
If in 2 minutes she can type 100, that means you must divide 100 by 2. 100 divided by 2 equals 50. You can check this by doing the same with 200 words in 4 minutes by dividing 200 by 4 to get 50. Xenas equation would be w=50m
Her average typing rate is 50 words per minute.
Here,
To find out Xena's typing rate (words per minute), we can use the data she recorded in the table.
We can calculate her typing rate by dividing the number of words she typed by the time it took her to type those words.
Let's perform the calculations:
For the first row (2 minutes, 100 words):
Typing rate = Words / Time
= 100 words / 2 minutes
= 50 words per minute
For the second row (4 minutes, 200 words):
Typing rate = Words / Time
= 200 words / 4 minutes
= 50 words per minute
For the third row (8 minutes, 400 words):
Typing rate = Words / Time
= 400 words / 8 minutes
= 50 words per minute
As we can see from the calculations, Xena's typing rate is consistent at 50 words per minute for all the recorded data.
Therefore, her average typing rate is 50 words per minute.

If the Internet consisted of four computers, there would be six possible connections. If it consisted of five computers, there would be ten possible connections. How many connections are possible with twenty computers
Answer:
80 possible connections
Step-by-step explanation:
Let the constant k = change in possible connection/number of computers
change in possible connections = 10 - 6 = 4
change in number of computers = 5-4 = 1
k = 10-6/5-4
k = 4/1
k = 4
Since k = possible connections/number of computers:
4 = possible connections/20
possible connections = 4 * 20
possible connections = 80
Hence the possible number of connections with 20 computers are 80 connections

Step-by-step explanation:
A farmer uses x lb of fertilizer per acre at a cost of 1.4 per pound, leading to a revenue of R = 700 – 400e -x/100 dollars per acre.
(a) How many pounds of fertilizer should be applied per acre to maximize profit? Write you answer in decimal form rounding to three decimal places
Number
pounds per acre.
(b) What is the maximum profit on a 200 acre farm?
$ Number
Answer:
The cost can be written as:
C(x) = $1.4*x
The revenue can be written as:
R(x) = $700 - $400*e^(-x/100)
And as you know, the profit is written as the difference between the revenue and the cost:
P(x) = R(x) - C(x)
P(x) = $700 - $400*e^(-x/100) - $1.4*x
Now we want to maximize this, then we must look at the zeros in the derivate of P(x)
dP/dx = P'(x) = (-1/100)*$400*e^(-x/100) - $1.4
The maximum will be when P'(x) = 0.
we can solve:
0 = (-1/100)*$400*e^(-x/100) - $1.4
$1.4 = (-1/100)*$400*e^(-x/100)
(-100)*$1.4 = $400*e^(-x/100)
$140 = $400*e^(-x/100)
($140/$400) = e^(-x/100)
0.35 = e^(-x/100)
Now we can apply the Ln() in both sides and get:
ln(0.35) = ln(e^(-x/100) ) = -x/100
-ln(0.35)*100 = x = 104.98
You should apply 104.90 pounds of fertilizer.
b) The profit per acre, is:
P(x) = $700 - $400*e^(-x/100) - $1.4*x
Then if you have 200 acres, the profit will be:
200*P(x) = 200*($700 - $400*e^(-x/100) - $1.4*x)
and the maximum profit is whit x = 104.98 pounds, then:
200*P(104.98) = 200*($700 - $400*e^(-104.98/100) - $1.4*104.98) = $82,604.98

What are the x and y-intercept of 4x – 8y = 2?
Garrett already has 5 bracelets made to sell at the craft fair. After working for 3 hours, he has a total of 11 bracelets made to sell at the craft fair. Write an equation in slope-intercept form where x represents the amount of time he spent making bracelets and y represents the number of bracelets made. How could you use the equation to predict the number of bracelets he will have made if he works for 5 hours?
A. y = 3x + 11; substitute 5 for x
B. y = 11x + 5; add 5 to the value of y
C. y = 5x + 2; add 5 to the value of y
D. y = 2x + 5; substitute 5 for x
Answer:
y = 2x + 5; substitute 5 for x
Answer:
Answer Choice D. He will make 10 bracelets in 5 hours (for the other question).
Step-by-step explanation:
He makes 2 braclets and hour so the slope is 2. He already has 5 bracelets so the y-intercept is 5.
find the angle of y dasdwadasdaw
Answer:
C
Step-by-step explanation:
Since angles x and y lie on a single straight line,
∠x +∠y= 180° (adj. ∠s on a str. line)
Given that ∠x= 42°,
42° +∠y= 180°
∠y= 180° -42° (-42° on both sides)
∠y= 138° (simplify)
Thus, option C is correct.
Johnny has a math test on Friday, an English test on Tuesday, and a social studies quiz on Wednesday. Over the weekend, he read 20 books. He needed to read 5 books for his English test and 2 books for his social studies quiz. A week later, Johnny received a 92 on his math test, 84 on his English test, and a 90 on his social studies quiz. What percent of books did Johnny read that were for social studies? Round to the nearest whole number (percentage). Do not include % in your answer. For example, if the answer is 19%, enter 19.
Answer: The percent of books did Johnny read that were for social studies=10%
Step-by-step explanation:
Given: Total books he read -= 20
Number of books for social studies = 2
The percent of books did Johnny read that were for social studies
[tex]=\dfrac{\text{Number of social studies books}}{\text{Total books}}\times100\\\\=\dfrac{2}{20}\times100\%\\\\=\dfrac{100}{10}\%=10\%[/tex]
Hence, the percent of books did Johnny read that were for social studies=10%

McKenzie told her friend, “If you increase my age by 8, multiply that quantity by 1/2 , and then subtract 6, you get 5.” Write an equation that matches McKenzie’s description using x as the variable.
a) x+8x1/2-6=5
b)1/2x+8-6=5
c)1/2(x+8-6)=5
d)1/2(x+8)-6=5
Answer:
D
Step-by-step explanation:
This follows PEMDAS
This first thing to do is add 8, so this must be P aka parentheses.
A and B are eliminated
Next is to M aka mutiply by 1/2
This eliminates C because if -6 was in the parentheses this would mean it is the next step as () takes priority. And this is not the case

Rewrite using a single positive exponent.
9^-3/9^6
(^ stands for exponents)
(explanations please if you don’t mind
Answer:
Its 9^-9
Step-by-step explanation
Because 9^-3 is on top, you have to take it to the bottom - this makes it positive. Now you have 1/(9^3*9^6). This give you 1/9^9 - or in other words 9^-9

485.1
Step-by-step explanation:
6 . 3
x 7 7
+ 4 4 . 1
+ 4 4 1 . 0
4 8 5 . 1
basically break up 77 to 70 + 7
multiply 6.3 with both parts of the 77 (70 + 7):
70 x 6.3 = 441
7 x 6.3 = 44.1
then add those two sums together to get 485.1
