The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas. What is the constant of proportionality (unit rate)?
Given:
The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.
To find:
The constant of proportionality
Solution:
We have,
[tex]P=0.25n[/tex] ...(i)
where P is the price and n is the number of bananas.
Price P is directly proportional to the number of bananas. So,
[tex]P\propto n[/tex]
[tex]P=kn[/tex] ...(ii)
Where, k is the constant of proportionality.
On comparing (i) and (ii), we get
[tex]k=0.25[/tex]
Therefore, the constant of proportionality is 0.25.
I have a circle that has a diameter of 10 in. Explain how to find the area of the circle.
Answer:
r squared × π
Step-by-step explanation:
Half of the Diameter (5in) squared
multiply by π
Answer:
31.4
Step-by-step explanation:
A=(pie) radius 2
To find the radius half the diameter
A=3.14(5in)2
A=15.7 x 2
A=31.4

A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form

Can somebody help please?
Answer:
-3
Step-by-step explanation:
1 × -3 = -3
-3 × -3 = 9
9 × -3 = -27
-27 × -3 = 81
81 × -3 = -243
The pattern is that each number is multiplied by -3, and 1 × -3 = -3.

How do I do such thing?
Answer:
a= -5
Explanation:
Rewrite the equation to be: 3^a=3^-1 / 3^4
Multiply by adding exponents :))
which would then be 3^a = 3^-5
Then, since the bases are the same then the a would equal negative (-) 5. :))
Hope this helps :)) Plz mark brainlest :))

Answer:
134
Step-by-step explanation:
There's 2 blue arrows where 39 is, and the same arrows where 4x+7 are. This means that they are the same length. So, 4x+7 = 39. Perimeter means you add, so 28+28+39+39 = 134.
