Answer:
f^-1 (x) = x/5
Step-by-step explanation:
f(x) = 5x
Replace f(x) with y
y= 5x
Exchange x and y
x = 5y
Solve for y
Divide each side by 5
x/5 = 5y/5
x/5 = y
The inverse is x/5

Answer:
X=32 and Y=51
Step-by-step explanation:
first to find the answer, we must establish that the sum of 3 angles in any triangle will equal 180 degrees, and both triangles are congruent then we can start making equations. Triangle STU has 2 numbers and one equation on it, the equation for the length of NP will give us y, but first we must get X from the equation for angle TUS which is congruent to angle MNP, so first we must add angle M and angle P together to find angle N, 142+24=166, 180-166=14, so angle N and angle U are both equal to 14 degrees, so, 2x-50=14 first add 50 to both sides then divide by 2 giving us 32=X. Now that we have x, we can find y, 2x32-y=13, we can determine m is equal to 13 m because segment SU is congruent to segment NP, SU is 13 meters, thus NP is 13 meters long as well. first multiply 32 and 2 giving 64, then subtract 64 from both sides, giving you -y=-51, but we don't stop here because y itself can't be negative as that's not what's being asked for, so divide both sides by negative 1 giving you Y=51

Step-by-step explanation:
Let f (x comma y )equals 4 x squared minus 9 x y plus 6 y cubed. Find f subscript x (x comma y ).
Answer:
Fx(x,y) = 8x -9y
Step-by-step explanation:
Given f(x,y) = 4x²-9xy+6y³, we are to find the derivative of the function with respect to x keeping y as constant.
Fx(x,y)
This is known as partial derivative of the function.
Fx(x,y) = 2(4)x^(2-1) - 9y + 0
Fx(x,y) = 8x -9y
Note that the differential of a constant is zero, hence the reason why 6y³ tends to zero since there are no x variable attached.
The mass of a hummingbird is
4,000 milligrams. Use a
proportion to convert 4,000
milligrams to grams
PLEASE HELPPPPP
Answer:
4 grams
Step-by-step explanation:
There are 1000 milligrams in a gram, so the proportion is 1g/1000mg=xg/4000mg
when you cross multiply, you get 1000xg=4000mg/ divide both sides by 1000 and you get xg=4, meaning x=4 grams

An astronaut is returning to Earth in a spacecraft. If the spacecraft is descending at a rate of 13.81 kilometers per minute, what will its change in height after 5 1/2 minutes?
Answer: -75.955
Step-by-step explanation:
the astronaut is descending 13.81km each minute, so multiply that by 5 and a half minutes you get 75.955. Since he is going down, his height will change by a negative 75.955 instead of a positive one.

Answer: -49
Step-by-step explanation:
Answer:
518
Step-by-step explanation:
Add 357 and 219 ( 594 )
( The negative symbol by an parenthesis means that there will be a 1 so it will be -1 )
Multiply -1 by each number in parenthesis
Then subtract -19 from -57 ( -76 )
Lastly you subtract -76 and 594
You should get your answer

One of the two points Seamus used to determine the slope of his trendline was (0.00286,4.27). If the slope of his trendline is 8,749 K, what is the y-intercept of his trendline
Answer:
c = -25017.87
Step-by-step explanation:
The slope of his trendline is 8,749 K
The two points that are used to find the slope of his trendline was (0.00286,4.27).
We need to find the y-intercept of his trendline. Slope of equation is given by :
y = mx +c
We need to find c.
Put y = 4.27, m = 8,749000 and x = 0.00286
c = y-mx
c = 4.27- 8,749000 (0.00286)
c = -25017.87
So, the y -intercept of his trendline is 25017.87

The angle on the top right is 90 degrees and the angle downwards is 34 degrees so subtract 90 and 34 to get 56.
A farmer's market sells pecans, walnuts, and cashews. They each have a
different cost and are priced per pound. Alyssa buys three pounds of walnuts
and four pounds of cashews and spends $32. Landon buys seven pounds of
pecans and five pounds of walnuts and spends $65. Tina buys 3 pounds of
pecans and 2 pounds of cashews and spends $22. Find the missing quantity
below.
D
Price per pound for Pecans = $
Answer:
Price per pound for Pecans = $5
Step-by-step explanation:
Let price per pound of walnut be x, price per pound of pecans be y and price per pound of cashew be z.
Thus;
For alyssa;
3x + 4z = 32 - - - (eq 1)
For Landon:
5x + 7y = 65 - - - (eq 2)
For Tina;
3y + 2z = 22 - - -(eq 3)
From eq 3, let's make z the subject;
z = (22 - 3y)/2
Putting this for z in eq 1 gives;
3x + 4((22 - 3y)/2) = 32
3x + 2(22 - 3y) = 32
3x + 44 - 6y = 32
3x - 6y = -12
Divide through by 3 to get;
x - 2y = -4 - - - eq(4)
Multiply through by -5 to give;
-5x + 10y = 20
Add this to eq 2 to get:
5x - 5x + 7y + 10y = 65 + 20
17y = 85
y = 85/17
y = 5
Thus, Price per pound for Pecans = $5

I'm in 6th grade what is 9p=72 solved mentally
Answer:
p=8
Step-by-step explanation:
A normal die (numbered 1-6) is fair if each outcome is equally likely. Therefore a 1 should come up of the time. If a fair die is rolled 360 times we would expect a 1 to come up 60 times (since 1 over 6 times 360 equals 60 ). If x represents the number of times a "1" is rolled then open vertical bar fraction numerator x minus 60 over denominator square root of 50 end fraction close vertical bar less than 1.96 gives the reasonable range for the number of times a "1" will come up in 360 rolls. If we roll the die 360 times and get a "1" 30 times, is our die a fair die? Show your work using the equation editor.
Answer:
Yes the die is fair as the calculated z= -0.224 is less than the Z∝= 1.96
Step-by-step explanation:
x`- u / s/√n< Z∝
x`- 60 /√50/√360 < 1.96
From the above we find that u = 60 and the sample size n= 360 S= √ 50
Z∝= 1.96
Here p = 1/6 ( the probability of getting a 1 out of 6)
q= 5/6
Since it is normal Standard deviation = √npq = √360 * 1/6*5/6= √50
If x`= 30
then
30 - 60 /√50/√360 < 1.96
-30/7.07*18.973 < 1.96
- 0.224 < 1.96
Yes the die is fair as the calculated z= -0.224 is less than the Z∝= 1.96 the null hypothesis that die rolled is fair is accepted.
