Answer:
(- 2, - 9 )
Step-by-step explanation:
The axis of symmetry passes through the vertex of the parabola.
Thus the x- coordinate of the vertex is x = - 2
To find y substitute x = - 2 into f(x)
f(- 2) = (- 2)² + 4(- 2) - 5 = 4 - 8 - 5 = - 9
Vertex = (- 2, - 9 )
Answer:
option D
Step-by-step explanation:
in a shoe store survey there are 200 customers.
given in the table is that people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.
We have been asked what percentage of people have basketball shoes.
People having basket ball shoes = 0.23 × 200 + 0.31 ×200
= 108
percentage of people wearing basket ball shoe = 
= 54 %
we can also find it by directly adding the given value and multiplying it by 100
= 0.23+0.31 = 0.54 ×100 = 54%
hence, the correct answer is option D
The values of the function include
f(x) = 5
g(x) = -2
f + g = x² + 4x - 3
<h3>How to compute the values?</h3>
f(x)=x²+2x+5,
f(x) = 0² + 2(0) + 5
f(x) = 5
2. g(x)=2x-2
g(x) = 2(0) - 2
g(x) = -2
3. f + g
= x² + 2x + 5 + 2x - 2
= x² + 4x + 3

3000 because if the hundredths place is 499 or less you round down but if its 500 or more you round up
Answer: 55 mph
Step-by-step explanation:
The family plans to drive for 220 miles and would like to do so in 4 hours.
To do so they would need an appropriate average speed.
Formula for speed is:
= Distance / Time
= 220 / 4
= 55 mph
