Answer:
y = -1/2 x + 25
The relationship is linear, but it takes some doing.
Step-by-step explanation:
Remark
This is a very interesting problem. I've never seen one quite like it. There is probably a much better way of solving it, but I did not discover it.
You have to introduce another variable which I labeled as z.
Let time = x
Let distance = y
Let the step away from the starting point = z which will be the same for x and y. So 18 and 16 the step away from the start is 3.
So as the time increases, the distance decreases. What we are going to do sort of resembles a parametric relationship.
t starts with 10
x = 10 + 4*(z - 1) and increases by 4 with each step
d starts with 20 and decreases by 2 with each step
y = 20 - (z - 1)*2
Now solve for z in each of the forgoing equations.
x = 10 + 4z - 4
x = 6 + 4z
x - 6 = 4z
(x - 6)/4 = z
y = 20 - 2z + 2
y = 22 - 2z
y - 22 = - 2z
(y - 22)/-2 = z
Since the zs must be kept the same, the left sides are equated
(x - 6)/4 = (y - 22)/-2 Cross multiply
-2(x - 6) = 4(y - 22) Remove the brackets.
-2x + 12 = 4y - 88 add 88 to both sides.
-2x + 100 = 4y Switch the sides
4y = - 2x + 100 Divide by 4
y = -1/2 x + 25
Now for sure you have to try this.
Let x = 14
y = -1/2 * 14 + 25
y = -7 + 25
y = 18
Try another one
Let x = 22
y = -1/2 * 22 + 25
y = - 11 + 25
y = 14
Those two at least check.
A fair coin is flipped twice. H is recorded for heads and T for tails after each flip. The notation for conditional probability is P(H on 2nd flip|H on 1st flip). Which notation is the probability of the two events being not independent?
Answer:
The Notation for each event Not been independent = P( HT ) or P( TH )
Step-by-step explanation:
when A fair coin flipped ; P( H ) = 0.5 and P( T ) = 0.5
Hence when it is flipped twice the possible outcome = 4
= HH , HT , TT, TH
Since Notation for conditional probability = P ( HH ) this shows that each flip is independent
The Notation for each event Not been independent = P( HT ) or P( TH )
Answer: P(H on 2nd flip|H on 1st flip)=P(H on 2nd flip)

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Hypotenuse² = Base² + Length²
The height of the building is 32.8 feet
What is the Pythagorean theorem?Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
If you place a 26-foot ladder against the top of a building and the bottom of the ladder is 20 feet from the bottom of the building.
This can be written as,
Hypotenuse = 26 feet
Base = 20 feet
Height = height of the building
Now,
Applying the Pythagorean theorem.
Hypotenuse² = Base² + Length²
26² = 20² + Height²
Height² = 676 + 400
Height² = 1076
Height = √1076
Height = 32.8 feet
Thus,
The height of the building is 32.8 feet

Answer:
The second one
Step-by-step explanation:
A visual for law of sines can be found below
Sin (an angles) over its opposite side length is equal to sin ( a different angle) over its opposite side length
In the given triangle we are given side length BC and side length AB
we are also given AB's opposite angle (40)
And we need to find side length BC's opposite angle (A)
That being said we are given enough information to set up an equation using the law of sines
Remember angle A's opposite side length is 16 and the angle that has a measure of 40 degrees' opposite side length is 12
so the equation would look like...
[tex]\frac{sin(40)}{12} =\frac{sin(A)}{16}[/tex]

Find the volume of the figure below. Leave your answer in terms of π.
Answer: 1539π cubic inches.
Step-by-step explanation:
In the figure, we have a hemisphere joined with a cylinder of the same diameter 18 inches.
Radius = 9 inches (half of diamter)
Volume of hemisphere = [tex]\dfrac23 \pi r^3[/tex]
Volume of cylinder = [tex]\pi r^2 h[/tex], where r= radius h= height
Volume of hemisphere= [tex]\dfrac{2}{3}\pi (9)^3=486\pi in.^3[/tex]
Volume of cylinder = [tex]\pi (9)^2 (13)=1053\pi\ in.^3[/tex]
Combined volume = 486π+1053π=1539π cubic inches.
Hence, the volume of the solid = 1539π cubic inches.

Amelia has 3 gallons of paint .Mason have 10 quarts .How many more pints of paint does AMELIA have then mason.
Answer:
4 Pints
Step-by-step explanation:
According to the scenario, calculations are as follows,
As we know, 1 gallon = 8 Pints
1 Quarts = 2 Pints
So, Amelia = 3 Gallons = 3 × 8 Pints = 24 Pints
Mason = 10 quarts = 10 × 2 Pints = 20 Pints
So, Number of more pints Amelia has = Amelia number of pints - Mason number of pints
= 24 pints - 20 pints
= 4 Pints
