Answer:
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) Domain will be [ 0, ∞ ]
Step-by-step explanation:
Given :
Weekly salary = $1000
Commission = 5% of all her sales
Let the number of sales be 's'
thus,
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) The domain here will be all the possible values of sales i.e 's'
Hence,
sales will always be positive
thus,
domain will be [ 0, ∞ ]
Answer:
b = - 21
Step-by-step explanation:
calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (- 6, 3)
m = 
= 
= - 4
y = - 4x + b ← is the partial equation
to find b substitute either of the 2 given points into the partial equation
using (- 4, - 5 ), then
- 5 = 16 + b ⇒ b = - 5 - 16 = - 21
You need to find the percent of the 125 surveyed students to find the number of estimated students that like pizza.
58/125 = .464 or 46.4%
1500*.464 = 696 students like pizza.
Hope this helps!

7:2
7/2
Step-by-step explanation:
7:2 is also equivalent to 7/2
Answer:
Step-by-step explanation:
It is given that an isosceles triangle has two sides of length a and base b, then the perimeter of an isosceles triangle= Sum of all the sides
⇒a+a+b=15.7
⇒2a+b=15.7
⇒b=15.7-2a
Also, we know that he sum of the lengths of any two sides of a triangle must be greater than the length of the third side that means,
⇒a+a>b
⇒2a>b
Now, substituting the value of b in the above equation, we get
2a>15.7-2a
⇒4a>15.7
⇒a>3.925
Now, b=15.7-2a, therefore b=15.7-2(3.925)=15.7-7.85=7.85
Thus possible value of b is 7.85.
