Answer:

Suppose you have a gift certificate worth $20 for one long-distance phone call. If the charge is $1.10 for the first minute and $0.42 for each additional minute , what is the longest that you can talk?

20 - 1.10 = 18.9

18.9 / 0.42

= 45

How to find (a) and (b)?​
rodikova [14]

Answer:

A) Gradient = -3

B) 3y - x = 7

Step-by-step explanation:

The curve has the equation;

y = x³ - 6x² + 9x + 1

We are given the pints it passes through as;

A(2,3) and P(3, 1)

A) to find the gradient, we will find the derivative of the given equation.

Thus;

Gradient = y' = 3x² - 12x + 9

At point A, x = 2. Thus;

Gradient = 3(2²) - 12(2) + 9

Gradient = 12 - 24 + 9

Gradient = -3

B) since the gradient of the tangent = -3, it means the gradient of the normal will be; -1/-3 = 1/3

Thus, equation of the normal to the curve at point A will be;

(y - 3) = ⅓(x - 2)

Multiply both sides by 3 to get;

3y - 9 = x - 2

3y - x = 9 - 2

3y - x = 7

Why is 1/8 greater than 1/10 but less than 1/3
zzz [600]

because the bigger the bottom or left number is the smaller the value unless t was like 10/10 that's bigger than them all

I can't figure out 3/30 is in a percentage decimal or fraction please help me!!
Kamila [148]
If I am correct I do think the answer is 0.10 in decimal,  in percentage it is 10% and fraction is 1 out of 30 I am not 100% sure so it would be better to double check
