A medical clinic is reducing the number of incoming patients by giving vaccines before flu season. During week 5 of flu season,

the clinic saw 90 patients. In week 10 of flu season, the clinic saw 60 patients. Assume the reduction in the number of patients each week is linear. Write an equation in function form to show the number of patients seen each week at the clinic.

Answer: An = 114 + (n - 1)-6

Step-by-step explanation:

Per 5 weeks there is  reduction of 30 patients. Divide by the common factor (5) and you see that per 1 week, there is a reduction of 6 patients. Going back in time to see what the first term was, you can create a explicit formula for this  function.

Hope this helps. Brainliest would be nice!

a volley ball player servers the ball. The ball follows a path given by the equation y=-0.01x^2+0.5x+3 where x and y are measure
dolphi86 [110]

Answer:

(a)

Distance from player should be 13.82 feet or 36.2 feet

(b)

The ball will go over the net

Step-by-step explanation:

we are given

The ball follows a path given by the equation

y=-0.01x^2+0.5x+3

where

x and y are measured in feet and the origin is on the court directly below where the player hits the ball

(a)

net height is 8 ft

so, we can set y=8

and then we can solve for x

8=-0.01x^2+0.5x+3

8\cdot \:100=-0.01x^2\cdot \:100+0.5x\cdot \:100+3\cdot \:100

800=-x^2+50x+300

-x^2+50x-500=0

x^2-50x+500=0

we can use quadratic formula

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\frac{-50\pm \sqrt{50^2-4\left(-1\right)\left(-500\right)}}{2\left(-1\right)}

x=5\left(5-\sqrt{5}\right),\:x=5\left(5+\sqrt{5}\right)

x=13.82,x=36.2

So, distance from player should be 13.82 feet or 36.2 feet

(b)

we can plug x=30 and check whether y=8 ft

y=-0.01(30)^2+0.5(30)+3

y=9ft

we know that

height of net is 8 ft

so, the ball will go over the net

Solve -9g+11<-15g-6+7g.
MArishka [77]

Answer: g>17

Step-by-step explanation:

-9g+11

Move the g-terms to the left side. and the independent terms to the right side. Remember to change the sign if you move from one side to another.

-9g+15g-7g

-16g+15g

-g

Divide by -1 on both sides to make g positive. When it comes to dividing by negatives in inequalities, the inequality sign changes direction.

\frac{-g}{-1}

g>17

Employees of a landscaping company built a retaining wall. They used brick to make the top 2/3 of the wall. The wall is 8and 1/2
IgorC [24]

Answer:

Height of the brick portion of the wall is 5.61 feet.

Step-by-step explanation:

Employees of the landscaping company used brick to build the top 2/3 of the wall. The total dimensions of the wall are 8 and 1/2 * 2 and 3/4 feet. So the height of the wall = 8 and 1/2 feet or in other words 8.75 feet.

Height of the brick portion of the wall = 2/3 * 8.5 = 0.66 * 8.5 = 5.61 feet

So the height of the brick portion of the wall is 5.61 feet.

Non brick portion of the wall is 8.5 - 5.61 = 2.89
