PLEASE HELP ME!!! An equation of the line tangent to the graph of y = 2x+3/3x-2 at the point (1,5) is
Answer: 13x + y = 18
Step-by-step explanation: 13x + y = 18 is equal to y = -13x + 18.
The derivative is y' = -13/3x-2^2.
With the derivative, you get -13 for slope and plug it in to get y - 5 = -13x + 13.
Move it around and you get 13x + y = 18.
Hope this helps!
We want to find the equation of the tangent line to a given point in a given function.
The correct option is B: 13*x + y = 18
So we want to find the equation of the tangent line to the function.
[tex]y = \frac{2x + 3}{3x - 2}[/tex]
at the point (1, 5).
To get the slope of that line, we need to evaluate the derivate of the function in the x-value of the point, the derivate of the function will be:
[tex]y' = \frac{2}{3x - 2} - 3*\frac{2x + 3}{(3x - 2)^2}[/tex]
Now we evaluate this in the x-value of the point, which is x = 1.
[tex]y' = \frac{2}{3*1 - 2} - 3*\frac{2*1 + 3}{(3*1 - 2)^2} = -13[/tex]
Then the line will be something like:
y = -13*x + b
To find the value of b, we use the fact that the line must pass through the point (1, 5). This means that when x = 1, we have y = 5.
Replacing that in the line equation we get:
5 = -13*1 + b
5 + 13 = b
18 = b
Then the equation of the line is:
y = -13*x + 18
Or, rewriting it.
13*x + y = 18
So the correct option is B.

A skydiver was directly above a ferris wheel when he jumped out of the plane. His friend was watching at the landing field and looking up at the airplane at an angle of 50°. The friend’s eyes were 5.5 feet above the ground when looking up, and he was standing 1050 ft from the ferris wheel. How high was the skydiver when he jumped?
Using the slope concept, it is found that the skydiver has at a height of 1257 ft when he jumped.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem:
The vertical change is of x - 5.5, in which x is the skydiver's height.The horizontal change is of 1050 ft.The angle is of 50º.Hence:
[tex]\tan{50^\circ} = \frac{x - 5.5}{1050}[/tex]
[tex]x - 5.5 = 1.19175359259 \times 1050[/tex]
[tex]x = 1257[/tex]

Answer:The first is a function but the second isn’t.
Step-by-step explanation: The numbers in the first circle (domain) should only point to one number in the second circle (range). Meaning the domain should only have one arrow for it to be a function. Therefore the first problem is a function, but the second problem is not. For

Supongamos que estás en el infierno y el diablo te reta a un juego. Él piensa en un número natural.Cada día, tú tendrás una oportunidad de adivinar ese número (él nunca cambia el número que pensó). Si lo adivinas, el diablo te permitirá salir del infierno.Recuerda que tienes una eternidad para adivinar, la pregunta es: ¿Cuál es el orden de los números naturales que adivinarías?

A squirrel runs across a road in 3 seconds. The road was more than 34 feet wide. Which inequality can be used to determine the squirrel’s speed? What is the solution to the inequality? Round to the nearest tenth, if necessary. How can you interpret the solution?.
Answer:
✔ 3r > 34
✔ r > 11.3
✔ The squirrel ran faster than 11.3 feet per second.
Step-by-step explanation:
The inequality used to define the squirrel's speed is 3r > 34
What is an inequality?
'In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal.'
According to the given problem,
Let the speed of the squirrel be x feet per second
We know,
Speed × Time = Distance
Distance given is greater than 34 feet
Inequality of the given problem,
3x > 34
⇒ x > 34/3
⇒ x > 11.3 feet/second
Hence, we can conclude that the speed of the squirrel is more than 11.3 feet per second.

A pack of cinnamon scented pencils sell for $4.00 what is the sales tax rate if the total cost of the pencils is $4.32
Answer:
8%
Step-by-step explanation:
To get the answer we can use proportion. We know that 4$ its 100% and 4.32 its 100% + taxes.
4$ ---------- 100%
4.32 -------- x
cross multiply now
4x=4.32*100%
4x=432% /:4
x=108%
We know that 4.32 its 100% + taxes=108% so to get taxes we have to subtract 108-100.
108%-100%=8% - its the answer.
Answer:
8%
Step-by-step explanation:
$4 represents the sale price
4.32 - 4 =$ .32 represents the sale tax
Tax rate is the percentage $ .32 out of $4.
4 is 100%
.32 is x%
Cross multiply to find x, and divide by 4
x= (.32·100) / 4
x = 8
The tax rate is 8%.

Can anyone helps me with this question. Look at the numbers ; 2,8,7,6,8,3,8. Find the
Mean
Median
Mode
Range
Answer:
1. Mean:
6
2. Median:
7
3. mode:
8
range:
6
Explanation:
Mean:
To find the mean you must add all the digits and divide them by the number of numbers there.for eg: 1,4,6,5,4
The number of numbers there is 5 so I added these numbers and divide them by 5.
Median:
To find the median you must arrange all the numbers in order and find the middle number eg: 1,2,3,4,5
The middle number is 3 as u can see there
Mode:
In the mode, you find the number that appears the most.
for eg: 1,3,3,4,5
The number appearing here the most is the 3
Range:
you minus the highest number from the lowest number
eg: 1,2,3,4,5
5-1 is 4 so the answer for the range is 4
