Independent variable = $20
dependent variable = $0.05 cents per min
y = total month cost
x = month minutes used
y = 20 + 0.05x
Answer:
the roots and vertex
Step-by-step explanation:
you can find the vertex by using vertex form y=a(x-h)^2+k you find the roots by solving the quadratic equation
Draw a diagram! Lets say the width is x, then the length must be 2x.
Area = length x width
2x x x = 8sq meters
2x^2 = 8
x^2 =4
x = √4
x = 2
we found the width the length is two times the width, making it 4 meters.
The thirty-second term is 143
Further explanation:
As it is already given that the given sequence is an arithmetic sequence
We have to find the common difference first
So,
The common difference is 5.
And first term is -12
The explicit formula for arithmetic sequence is:
Putting the values in the formula
Putting n=32 in explicit formula
The thirty-second term is 143

Answer: 405 students
Step-by-step explanation:
From the question, Banneker Middle School has 750 students and we are told that Lynn surveys a random sample of 50 students and finds that 27 have pet dogs. The number of students at the school that are likely to have pet dogs goes thus:
Since out of 50 students surveyed, 27 have pet dogs, this means we multiply the fraction by 750. This can be mathematically written as:
= 27/50 × 750
= 27 × 15
= 405
This means 405 students are expecting to have pet dogs.
