Let f be differentiable such that f(-2)=3,f(3)=5, f'(-2)=4 and f'(3)=6. Let g be differentiable functions such that g(x)=f^-1 (x) for all x. What is the value of g'(3)
Answer:
[tex]g'(3)=\frac{1}{4}[/tex]
Step-by-step explanation:
There is a rule in calculus that tells us that:
[tex]g'[f(x)]=\frac{1}{f'(x)}[/tex]
In this case, we know that f(-2)=3, therefore:
g'(3)=g'(f(-2))
So, if we used the rule, we would get that:
[tex]g'[f(-2)]=\frac{1}{f'(-2)}[/tex]
we know that f'(-2)=4, so:
[tex]g'[f(-2)]=\frac{1}{4}[/tex]
or:
[tex]g'[3]=\frac{1}{4}[/tex]

Answer:
FD≈25.94.. rounded = 26
Step-by-step explanation:
FD²=12²+(4x+11)²
FD²=144+16x²+88x+121
FD²=265+16x²+88x
also
FD²=12²+(13x-16)²
FD²=144+169x²-416x+256
FD²=400+169x²-416x
thus
265+16x²+88x = 400+169x²-416x
16x²-169x²+88x+416x+265-400 = 0
-153x²+504x-135 = 0
we will solve this quadratic equation by suing the quadratic formula to find x
x=(-504±sqrt(504²-4(-153)(-135)))/2(-153)
x=(-504±[tex]\sqrt{504^{2}-4(-153)(-135) }[/tex])/2(-153)
x=(-504±[tex]\sqrt{254016-82620 }[/tex])/-306
x=(-504±[tex]\sqrt{171396}[/tex])/-306
x=(-504±414)/-306
x=(-504+414)/-306 and x=(-504-414)/-306
x=-90/-306 and x=-918/-306
x= 5/17 , 3
substituting x by the roots we found
check for 5/17:
4x+11 = 4×(5/17)+11 = (20/17)+11 = (20+187)/17 = 207/17 ≈ 12.17..
13x-16 = 13×(5/17)-16 = (65/17)-16 = (65-272)/17 = -207/17 ≈ -12.17..
check for 3:
4x+11 = 4×3+11 = 12+11 = 23
13x-16 = 13×3-16 = 23
thus 3 is the right root
therfore
ED=23 and CD=23
FD²=FE²+ED² or FD²=FC²+CD²
FD²=12²+23²
FD²=144+529
FD²=673
FD=√673
FD≈25.94.. rounded = 26
Answer:
FD = 25.94 or 26Step-by-step explanation:
ED = CD ...... ( Tangent secant Property)
4x + 11 = 13x - 16
11 + 16 = 13x - 4x
27 = 9x
27÷9 = x
3 = x
so,
ED = 4x + 11 = 4(3) + 11
ED = 23
FE = 12 ...... ( given )
ΔFED = 90° ...... ( tangent property )
so,
FD² = FE² + ED²
FD² = 12² + 23²
FD² = 144 + 529
FD² = 673
FD = √673
FD = 25.94
FD = 26 (approx )

(3 - x) cm
(2x + 5) cm
The diagram shows a cuboid of volume V cm3
(a) Show that V = 15 + 16x - x (squared) - 2x (cubed)
Answer:
Step-by-step explanation:
Length of the cuboid = ((2x + 5) cm
Width of the cuboid = (3 - x) cm
Height of the cuboid = (2x + 5) cm
Since, volume of the cuboid = Length × Width × Height
= (2x + 5)(3 - x)(x + 1)
= [2x(3 - x) + 5(3 - x)](x + 1)
= (6x - 2x² + 15 - 5x)(x + 1)
= (-2x² + x + 15)(x + 1)
= x(-2x² + x + 15) + 1(-2x² + x + 15)
= -2x³ + x² + 15x - 2x² + x + 15
= -2x³ - x² + 16x + 15
≈ 15 + 16x - x² - 2x³
A shelf has different sizes of bottles of laundry detergent. This line plot shows the number of cups of laundry detergent in each bottle. Eric buys the kind of detergent that has the most bottles. He uses 18 cup for every load of laundry he does. How many loads of laundry can Eric do with his bottle of laundry detergent? Enter your answer in the box. Loads
Answer:
2 / 3 loads
Step-by-step explanation:
From. The plot, we can conclude that, the detergent that has the most bottles is that with 5 ; the number of cups in the detergent with 5 bottles is 12 cups
Number of cups used for each load of laundry = 18 cups
The loads of laundry Eric can do is thus :
Number of cups of detergent / number of cups used for each load of laundry
= 12 / 18
= 2 / 3 loads

Find the percent of change. Round to the nearest
tenth, if necessary. Then state whether the percent of
change is an increase or a decrease.
30. From 55 lb to 24 lb
Answer:
Decease in weight by 56.4%
Step-by-step explanation:
From 55 lb to 24 lb,
There is a decrease in the weight from 55 lb to 24 lb.
For the percentage decrease in weight,
Change in weight = 55 - 24
= 31 lb
Percentage change in weight = [tex]\frac{\text{Total change}}{\text{Initial value}}\times 100[/tex]
= [tex]\frac{31}{55}\times 100[/tex]
= 56.36%
≈ 56.4%
Therefore, there is a decease in weight by 56.4%.

In Las Vegas, a particular sports bet has about a 30% chance of winning. If the bet wins, the bettor will win 15
dollars. If the bet loses, the bettor will lose 10 dollars.
The expected return of placing one of these bets is -2.50 dollars.
Which of the following statements are true?
Choose all answers that apply:
The average return per bet from 2 of these bets must be exactly -2.50 dollars.
It is possible for a bettor to place 2 of these bets and win both of them.
If a bettor places a large number of these bets, they should expect to average a return of about
-2.50 dollars per bet.

Answer:
y = 3x
Step-by-step explanation:
Slope equation:
y2 - y1
--------
x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
(0,0) (2,6)
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x

What is the total cost?*
Answer:
$545.1575
Step-by-step explanation:
Given function:
499,9.25Solve ways:
combine 9.25% of 499 and 499Multiply 9.25 by 0.01:
[tex]9.25%[/tex]·[tex]0.01=0.0925[/tex]Multiply the cost by 0.0925:

Lindas aunt zoe charges her a nominal amount for watching her two children aunt zoe charges $2.50 per day plus $1.75 per hour one day linda paid her aunt $14.75 how many hours did aunt zoe watch the children
Answer:
7 hours
Step-by-step explanation:
the function of the earning of Zoe = 2.50 + 1.75h
2.5 = base fixed amount
1.75 varies based on the hours
h = hours
2.50 + 1.75h = 14.75
to solve for h
subtract 2.5 from both sides and then divide by 1.75
14.75 - 2.5 = 1.75h
12.25 = 1.75h
h = 7

If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?
Answer: 0.71
Step-by-step explanation:
Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:
P(R) + P(C) = 1
0.29 + P(C) = 1
P(C) = 1 - 0.29
P(C) = 0.71
Therefore, the probability of a cup drink being cola flavour is 0.71.
