Answer: A. $17.28
Step-by-step explanation:
Given : Lindy works at a pizza restaurant and gets a 10% employee discount.
here m, 10% can be written as 0.10.
She knows that if she orders d drinks and a medium pizza with t toppings, her total cost can be found using this expression:
For d= 4 and t= 3 , we have
Therefore, the total cost for Lindy = $ 17.28
Answer:
To make f continuous at ,
should be defined
Step-by-step explanation:
A function, let say , is defined at
is continuous at
If the limit of as
approaches
is equal to the value of
at
.
Mathematically it is written as:
if
then
is continuous at
.
So from the above definition, we conclude that:
To make f continuous at ,
should be defined
i.e.
if
then
is continuous at
.
Answer:
The coordinates of B is (3, - 5)
Step-by-step explanation:
A(6, 1)
C(2, -7)
Coordinates of point B such that AB = 1/3 × BC
Hence we have;
Therefore BC = 3/4 × AC
Hence, AB = 1/3 × BC = 1/3 × 3/4 × AC = 1/4 × AC
AC = √((6 - 2)² + (1 - (-7))²) = √(16 + 64) = √80 = 4·√5
AB = 1/4 × 4·√5 = √5
Therefore;
AB² = (x - 6)² + (y - 1)² = 5
Slope = (1 - (-7))/(6 - 2) = 2
Hence the y coordinate of B = -7 + sin(tan⁻¹(2)) ×√5 = -5
The x coordinate of B = 2 + cos(tan⁻¹(2)) ×√5 = 3
The coordinates of B = (3, - 5)
