find the inverse of f(x)= 2x/(5x+6)
Answer:
[tex]f(x) = \frac{2x}{5y+6}[/tex]
Step-by-step explanation:
Answer:
Below!
Step-by-step explanation:
f(x) = 2x/5x+6
Sub y for f(x) : y = 2x/5x+6
Swap x and y : x = 2y/5y+6
Multiply both sides by 5y+6 : 2y = (5y + 6) x
Distribute x : 2y = 5xy + 6x
Change sign : 2y - 5xy = 6x
Factor out y : (2-5x)y = 6x
Divide both sides by 2-5x : y = 6x/2-5x
Substitute for y : f^-1(x) = 6x/2-5x
Answer: f^-1(x) = 6x/2-5x

Step-by-step explanation:
m<UZV = 180-108=72°
arc YVU = 180+72+85= 337°
diameter XV = 24 m
so, the length of arc YVU =

Step-by-step explanation:
The larger the magnitude of the vertical scale factor, the quicker the graph takes on higher values. That makes its appearance narrower.
Here, you want to list the functions in decreasing order of vertical scale factor:
g(x) . . . scale factor 4

Entry function to model the situation. Then find the value of the function after the given amount of time. Use T as your variable and round you're answer to the nearest sent. Fiona salary is $21000, and she excepts to receive a 3% raise each year; 8 years. The function is y= Her salary after 8 years is $=
Answer:
her salary after 8 years is $26,602
Step-by-step explanation:
Given that
Fiona salary is $21,000
She received 3% raise each year
We need to find her salary after 8 years
So, here we apply the future value formula
i.e.
= Present value × (1 + rate of interest)^number of years
= $21,000 × (1 + 0.03)^8
= $21,000 × 1.03^8
= $26,602
hence, her salary after 8 years is $26,602

The ramp on the back of a moving van is 7 ft high and rises at an angle of 28°. How long is the ramp? Round to the nearest foot.
Answer:
6 feets
Step-by-step explanation:
Height of ramp = 7feets
θ = 28°
Length of ramp = x
Using trigonometric relation :
Sin θ = opposite / hypotenus
Sin 28 = 3 / x
0.4694715 = 3 / x
0.4694715x = 3
x = 3 / 0.4694715
x = 6.39 feets
The length of the ramp = 6 feets

The sum of the arithmetic series is:
893
What are arithmetic progressions?
An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.
An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.
Solution:
Given:
a1 = 11, a2 = 15 and an=83
Step-1:
d= a2 ₋ a1
d= 4
Now, an = a ₊ (n ₋ 1)d
83 = a ₊ (n ₋ 1)4
83 = 11 ₊ 4n ₋4
83 = 7 ₊ 4n
4n = 83 ₋ 7
n = 19
Step-2:
Now, Sn = n/2 (a1 ₊ an)
Sn = 19/2 (11 ₊ 83)
Sn = 19/2 ₓ 94
Sn = 893
Hence we get the answer as 893
