d varies jointly with w and p and inversely with u
In your equation, use k as the constant of proportionality.
Answers
Answer:
huh?
Step-by-step explanation:
If D varies jointly with w and p and inversely with u, it can be written as D = (kwp)/u, where k is the constant of proportionality.
What is proportion?A mathematical comparison of two numbers is known as proportion. If two sets of given numbers increase or decrease in the same ratio, the ratios are said to be directly proportional to each other, according to proportion.
How to solve this problem?Given that D varies jointly with w and p. Then it can be written as
D ∝ w × p ...(1)
Again D varies inversely with u.
Then, D ∝ 1/u ...(2)
From (1) and (2), D ∝ (wp)/u ...(3)
We can take k as the constant of proportionality.
So, (3) becomes, D = k(wp/u) = (kwp)/u
Therefore, if D varies jointly with w and p and inversely with u, it can be written as D = (kwp)/u, where k is the constant of proportionality.

Y = 5x + 4
Y = 3x+10
solve for the solution (x,y)?
Answers
Answer:
The solution (x,y) is (3,19).
Step-by-step explanation:
We are given two equations for y.
y = 5x + 4
y = 3x + 10
They are equal, which means that we can find x. So
5x + 4 = 3x + 10
2x = 6
x = 3
With x, we can find y:
y = 5*3 + 4 = 19
So the solution (x,y) is (3,19).

Two sides of a triangle have the same length. The third side measures 3 m less than twice that length. The perimeter of the triangle is 25m. Find the lengths of the three sides.
Answers
Answer:
two sides have the length of 7m
third side is 11m
Step-by-step explanation:
perimeter is the sum of all sides
let 'n' = length of congruent sides
let '2n - 3' = length of third side
25 = n + n + 2n - 3
25 = 4n - 3
28 = 4n
n = 7m
2(7) - 3 = 11m

Sixteen players participated in a tennis tournament. Three players will be awarded for first, second, and third prize. In how many different ways can first, second and third prizes be awarded?
Answers
Answer:
Total number of ways in which first, second and third prizes will be awarded = 560
Step-by-step explanation:
As given,
There are 16 players participated in a tennis tournament.
and 3 players will be awarded for first, second, and third prize.
As we know,
ⁿCₓ = [tex]\frac{n!}{x! (n-x)!}[/tex]
n = the number of items.
x = how many items are taken at a time.
As given, n = 16 , x = 3
⇒¹⁶C₃ = [tex]\frac{16!}{3! (16-3)!} = \frac{16!}{3! (13)!} = \frac{16.15.14.13!}{3! (13)!} = \frac{16.15.14}{3!} = \frac{16.15.14}{3.2.1} = \frac{3360}{6} = 560[/tex]
∴ we get
Total number of ways in which first, second and third prizes will be awarded = 560

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=57(0.4)^x
Answers
Answer:
Decay, 60%
Step-by-step explanation:
Remember that the exponential function is written in the form [tex]y=ab^x[/tex]. In this problem, a=57 and b=0.4. A function is considered a growth function when [tex]b>1[/tex]. Since 0.4 not greater than 1, this is an exponential decay function.
Now, to find the rate of decrease we can use part of the form [tex]y=a(1-r)^x[/tex].
[tex]1-r[/tex] represents the percentage decrease, in this case, 0.4. If that entire term is 0.4, we need to solve for [tex]r[/tex].
[tex]1-r=0.4\\r=0.6[/tex]
So, the rate of percentage decrease is 60%.

Explanation:
Segments DB and DC are the same length. This makes triangle BCD to be isosceles. Recall that the base angles of any isosceles triangle are congruent angles. The base angles are opposite the congruent sides.
So because DB = DC, this makes B = C the congruent base angles in question. Let's say they are x for now.
Also recall that for any triangle, the three angles always add to 180 degrees.
B+C+D = 180
x+x+44 = 180
2x+44 = 180
2x = 180-44
2x = 136
x = 136/2
x = 68
So angles B and C, of triangle BCD, are 68 degrees each.
This leads to angle BCD to be 68 degrees as well.
Now we'll turn to the Tangent-Chord Theorem. This says that the angle made between a chord and a tangent is the same measure as the inscribed angle that is opposite the chord.
In this case,
AB is the tangentDB is the chord we want to focus onangle ABD is the angle between the chord and tangentangle BCD is the angle opposite the chordSo because angle BCD is 68 degrees, so is angle ABD.

What is scientific notation?Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power such as 1.56×10⁷.
The given scientific notation is 3×10⁴.
To write scientific notation in ordinary number, multiply the number of 10 powers.
Now, 10⁴ can be expanded as 10×10×10×10=10000
So, 3×10⁴=3×10000
= 30000
