Let x represent number of bicycles and y represent number of tricycles.
We know that a bicycle has 2 pedals and a tricycle has 32 pedals as well.
We have been given that when the owner counted the total number of pedals of the cycles, he got 50. We can represent this information in an equation as:
We know that a bicycle has 2 wheels and a tricycle has 3 wheels.
We have been given that when the owner counted the total number of wheels of the cycles, he got 64. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, 14 tricycles were offered in the sale.
Answer:
sqrt 51
Step-by-step explanation:
You should use the pythagorean theorem, which states a^2+b^2=c^2. So the missing side length for the smaller triangle is sqrt{2^2+3^2}=sqrt{4+9}=sqrt{13}. And the side length x is sqrt{8^2-sqrt{13}^2}=sqrt{64-13}=sqrt{51}
Answer:
Look at the image.
Step-by-step explanation:
(36 ÷ 4) - (36 ÷ 9)
9 - 4
5
(8 × 3) - 12 = 12
24 - 12
12
Answer:
A.
B.Therefore the solution is defined on the interval:
6≤ x ≤ +∞
Step-by-step explanation:
Given differential equation is
Integrating both sides:
........(1)
Given y(0)= 6
it means y=0 when x=6
Putting x=6 and y=0 in the equation (1)
Equation (1) become:
Therefore
(B)
The quantity under root must greater than or equal to zero.
Therefore,
When x≥0 then the value of is real other wise the value of is imaginary.
Therefore the solution is defined on the interval:
6≤ x ≤ +∞
As y varies inversely with x, we have a function of the form:
y = k / x
We must find the value of k:
For this we substitute y = 5 when x = 5.
We have then:
5 = k / 5
k = 5 * 5
k = 25
Then, the function is:
y = 25 / x
Answer:
the inverse variation function is:
y = 25 / x
