X^2/16 + y^2/25 =1 the length of the major axis is: 5 10 25

Major axis length = 10

Step-by-step explanation:

Given:

The equation given is:

The above equation represents a standard ellipse of the form:

If then 'a' is the semi-major axis length and 'b' is the semi-minor axis length.

If , then 'a' is the semi-minor axis length and 'b' is the semi-major axis length.

On comparing the given equation with the standard form, we get:

Here, b > a as 5 > 4. So, the length of major axis is twice the length of 'b' and is equal to:

Major axis length =

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
