Am I supposed to answer the sum of each one ?
Answer:
7 centimeters of rain will produce the maximum number of mosquitoes (49 millions of mosquitoes)
Step-by-step explanation:
we have the function
where
m(x) is the number of mosquitoes in Anchorage, Alaska (in millions of mosquitoes)
x is the rainfall (in centimeters)
This is a vertical parabola open downward
The vertex represent a maximum
The x-coordinate of the vertex represent the centimeters of rain that will produce the maximum number of mosquitoes
so
Convert the quadratic equation into vertex form
Factor -1
Complete the square
Rewrite as perfect squares
The vertex is the point (7,49)
therefore
7 centimeters of rain will produce the maximum number of mosquitoes (49 millions of mosquitoes)
Answer:
-3
Step-by-step explanation:
So they are essentially giving you x, so you replace it with -3.
H(-3) = 2/3 (-3) -1
2/3 × -3 = -2
-2 - 1 = -3
H(-3) = -3 ⬅This is a true statement.
Hope this helps :)
Given:
Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin.
To find:
The ratio of hours spent practicing violin to hours spent playing softball three different ways.
Solution:
We have,
Time spend on Softball = 5 hours
Time spend on Violin = 4 hours
The ratio to hours spent practicing violin to hours spent playing softball is
It can be written as
Therefore, the ratio of hours spent practicing violin to hours spent playing softball three different ways are and 4 to 5.
