Answer:

The number is n-0.75

Step-by-step explanation:

Here in this question, we are interested in giving a number which is 75% of 1 less than a number n.

The first thing we do here is to calculate the value of 75% of 1.

That would be;

75/100 * 1 = 0.75

So this value less than n will be;

n- 0.75

Complete the square to find the vertex of this parabola.PLEASE HELP!!
Paladinen [302]

Answer:

(1, 5 )

Step-by-step explanation:

Given

x² - 2x + y - 4 = 0 ( add 4 to both sides )

x² - 2x + y = 4

Complete the square on x² - 2x

add ( half the coefficient of the x term )² to both sides

x² + 2(- 1)x + 1 + y = 4 + 1, that is

(x - 1)² + y = 5

Subtract (x - 1)² from both sides

y = - (x - 1)² + 5

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

y = - (x - 1)² + 5 ← is in vertex form

with vertex = (1, 5 )

marshall27 [118]
Your ratio is 6:5

This means that it is 6/5.

You have to find a common number to either divide or multiply that can work for both the numerator and denominator.

6/5 doesn't have any common number to divide without getting a remainder

But we can multiply by a common number such as 2

6×2 = 12
5×2 = 10

= 12/10. ☆= the ratio is 12 : 10

or even by 3, =the ratio 18:15

Find the relative rate of change fro each of the following functions. f(x)=x^3 -3x^2
Reika [66]
The rate of change is simply the derivative of a function with respect to the other variable. In this case the rate of change with respect to x is desired. Therefore 

f(x) = x^3 - 3x^2
f'(x) = 3x^2 - 6x

therefore the rate of change of y with respect to x is dy/dx = 3x^2 - 6x

puteri [66]

Answer:

(- 35, - 5 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), hence

(- 35, 5 ) → (- 35, - 5 )
