Identify each expression that represents the slope of a tangent to the curve y = 1/x+1 at any point (x,y)
Answers
The expressions that represent the slope of a tangent to the curve [tex]y = \frac{1}{x+1}[/tex] are [tex]m = \lim_{h \to 0}\frac{\frac{1}{x + h + 1} - \frac{1}{x + 1} }{h}[/tex] and [tex]m = -\frac{1}{(x + 1)^{2}}[/tex], respectively.
How to find an expression for the slope at any point of a function
The slope at any point of the function can be found by definition of derivative following algebraic handling:
[tex]m = \lim_{h \to 0}\frac{\frac{1}{x + h + 1} - \frac{1}{x + 1} }{h}[/tex]
[tex]m = \lim_{h \to 0} \frac{\frac{x+1 - x - h - 1}{(x + h + 1)\cdot (x + 1)} }{h}[/tex]
[tex]m = -\lim_{h\to 0} \frac{1}{(x + h + 1)\cdot (x + 1)}[/tex]
[tex]m = -\frac{1}{(x + 1)^{2}}[/tex]
Thus, the expressions that represent the slope of a tangent to the curve [tex]y = \frac{1}{x+1}[/tex] are [tex]m = \lim_{h \to 0}\frac{\frac{1}{x + h + 1} - \frac{1}{x + 1} }{h}[/tex] and [tex]m = -\frac{1}{(x + 1)^{2}}[/tex], respectively.

Answers
Answer:
It is the one on the bottom right
Step-by-step explanation:
First of all, we have to start at (0,0), so we can cross out the one on the top left and top right, as they does not.
Also, the one on the bottom right does not go back to the ground, though just stays in the air, but the one on the bottom right dows go back to the ground.
So, its the one on the bottom right

Axel owns stock in a company. He purchased the stock In January at a price of $250 a share. From January to February, the stock price decreased by 38% a share. From February to March, the stock price increased by 20% a share. By what percentage did the price of the stock decrease per share from January to March?
Answers
Answer:
25.6%
Step-by-step explanation:
Purchase price = $250 / share
Jan - feb : 38% decrease
(100 - 38)% * 250 = $155
February - March : 20% increase
(100 + 20)% * $155
120% * $155 = $186
Percentage decrease from January to March :
[(250 - 186) / 250] * 100%
(64 / 250) * 100%
0.256 * 100%
25.6%

A dog walking service offer daily services in weekly service in the winter the ratio decor Shmurda weekly customer was 125 however in Springmore Cozumel motivate the daily service because of all the nice weather out of the chair while change the ratio was 4 to 2 if there was a 125 weekly? In the winter how many dell customer would it be in the spring
Answers
Answer:
100 customers
Step-by-step explanation:
The computation of the number of dell customers would be in the spring is shown below:
Given that
In winter season
The ratio of daily customers to weekly customers = 1:5.
In Spring season :
The ratio of daily customers to weekly customers = 4:2.
And, the Number of the weekly customer in the winter is 125
So if we can see that the weekly customers would be 5 times of daily customers
So, the daily customers in winter is
= 125 ÷ 5
= 25 customers
Now in the spring it would be
= 25 × 4
= 100 customers
Two rectangular rugs are ordered at Cardi’s furniture: small rugs and large rugs.
Small rugs are 36 inches long and 18 inches wide.
Large rugs are 90 inches long and 45 inches wide.
a. Are the rugs similar shapes? Explain your reasoning.
b. Find the ratio of the two perimeters and the ratio of the two areas. Is there anything you notice about these ratios? What can you deduce?
c. It takes 180 feet of yarn to create a square foot of either rug. How many inches of yarn are needed to make the small rug? How many feet or yarn is needed to make the large rug?
d. If a “skein” of yarn costs $4.50 and one skein is exactly 180 feet of yarn, how many skeins of yarn are needed to make the large rug? Given this answer what is the lowest Cardi’s must sell the large rug in order to make a profit
PLEASE HELP EVEN IF U CAN ANSWER JUST 1
Answers
Answer:
a.) yes they are similar shapes, the width for both rugs is 1/2 of the length. This means that they are both similar in shape.
b.) 2:5 (perimeter rug 1 and 2 compared), 4:25 ( area for 1 and 2). The numers in the perimeter ratio are the square root of the numbers in the area ratio.
c.) You will need 648 sq in for the small rug and 4050 sq in for the large rug.
d.) 2: she has to sell the large rugs x>$9 and the small rugs for s>$1.50
Step-by-step explanation:
total perimeter for rug 1 = 108 For rug 2 = 270
area for run 1 = 648 For rug 2 = 4050
180 ft = 2150 in
The large rug needs two skeins of yarn which cost 9 dollars, if she wants to make a profit she will have to sell them over that price.
You can make 3 small rugs with one skein meaning if she wants to make a profit from the small rugs she has to sell them over 1/3 of the price of the skein (which is sold for $4.50). She will have to sell the small rug for over $1.50

Answers
Answer:

Step-by-step explanation:
First, I started by subtracting 5 minutes from the additional 25 minutes of running that couldn’t fit into another hour. That would bring the running time to 2 hours and 20 minutes and the end time to 2:00 pm. Take away another 2 hours and you would be left with 20 minutes, with a start time of 12:00 pm. Get rid of the last 20 minutes and you get the start time as 11:40 am.
Check:
11:40 + 2 hours = 1:40 pm
1:40 + 20 minutes = 2:00 pm
2:00 + 5 minutes = 2:05
This is correct

A UFO is coming in to pick up some test subjects. Their elevation above the ground is 60,000 feet. Their laser sights tell them that a direct (diagonal) path to the nearest landing area is 90,000 feet away. What is the angle of depression as they come in to land?
Answers
Answer:
41.83°
Step-by-step explanation:
It is given that :
The vertical distance of the UFO from the ground = 60,000 feet
The diagonal distance of the landing area to the UFO = 90,000 feet
In order to find the angle of depression, we have to use the trigonometric ratios, i.e.,
[tex]$\sin \ \theta = \frac{\text{perpendicular distance}}{\text{hypotenus}}$[/tex]
[tex]$\sin \ \theta = \frac{60,000}{90,000}$[/tex]
[tex]$\sin \ \theta = \frac{2}{3}$[/tex]
[tex]$\sin \ \theta = 0.667$[/tex]
∴ [tex]$\theta = \sin^{-1 }(0.667)$[/tex]
= 41.83°
1 Which of the following could be the sides of a right triangle? Check all that apply. A. 10, 24, 26 B. 4, 5, 9 C. 18, 24, 30
Answers
Answer:
A and C
Step-by-step explanation:
Let Triangle ABC is a right angle traingle.
From Option A
AB= 24, BC= 26 and AC=10
By Pythagorean Triplet
(AB)^2 + (AC)^2 = (24)^2 + (10)^2
= 576+100
(AB)^2 + (AC)^2 = 676 ---------------- (I)
(BC)^2 = 26^2 = 676 -------------------(ii)
From (I) and (ii)
(BC)^2 = (AB)^2 + (AC)^2
Therefore, the sides 10,24 and 26 are the sides of the right angle triangle.
From Option C
AB= 18, BC= 30 and AC=24
By Pythagorean Triplet
(AB)^2 + (AC)^2 = (18)^2 + (24)^2
= 324+576
(AB)^2 + (AC)^2 = 900---------------- (I)
(BC)^2 = 30^2 = 900 -------------------(ii)
From (I) and (ii)
(BC)^2 = (AB)^2 + (AC)^2
Therefore, the sides 18, 24 and 30 are the sides of the right angle triangle.
