<u>Answer:</u>

p (3) = 7.83

<u>Step-by-step explanation:</u>

We are given the following expression and we are to evaluate it given that the value of p = 3:

p ( x ) = \frac { 9 0 } { 9 + 5 0 e^ { - x } }

Substituting the given value of p to get:

p ( 3 ) = \frac { 9 0 } { 9 + 5 0 e^ { - 3 } }

p ( 3 ) = \frac { 9 0 } { 11.489 }

p ( 3 ) = 7.83

Answer:

If it is p(x)=\frac{90}{(9+50e^{-x})}, then: p(3)=7.83

If it is p(x)=\frac{90}{9}+50e^{-x}, then: p(3)=12.48

Step-by-step explanation:

To solve this exercise you must substiute x=3 into the expression given in the problem.

1) If the expression is p(x)=\frac{90}{(9+50e^{-x})}, you obtain:

p(3)=\frac{90}{(9+50e^{-(3)})}

p(3)=7.83

2) If the expression is p(x)=\frac{90}{9}+50e^{-x}, you obtain:

p(3)=\frac{90}{9}+50e^{-(3)}\\p(3)=12.48

Point Find the length of segment CD with C(2,3) and D (-3, 15​
gladu [14]

Step-by-step explanation:

so, if the text is correct, the 2 points are

(2, 3) and (-3, 15).

the length of the line segment is the distance between both points.

did this we use Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.

so,

distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169

distance = sqrt(169) = 13 = length of line segment

A private school $860,000 in one year to pay all of its teachers and administrators. the school has a total of twenty-four teach
ehidna [41]
Hi there!

Let t be the number of teachers
Let a be the number of administrators

t+a=24
35,000t+40,000a=860,000
a=24-t
35,000t+40,000(24-t)=860,000
35,000t+960,000-40,000t=860,000
35,000t-40,000t=860,000-960,000
-5,000t=-100,000
t=-100,000/-5,000
t=20
a=24-t
a=24-20
a=4

Therefore there are 4 administrators and 20 teachers. 

Hope this helps!
