Plug in - 5 where X is.

f(- 5) = (- 5)^2 - ( - 5).

(- 5)( - 5) = 25 so now we have 25 - (- 5). Because there are two negatives back to back, the number becomes a positive so the equation becomes 25 + 5 = 30. 

f(- 5) = 30.

an 8lb cat has an IV flow rate of 2mL/kg/hr, how many mL's of fluids does the cat receive in 24 hours
Blababa [14]

Answer:

175 mL

Step-by-step explanation:

(a) Convert the mass of the cat to kilograms

 1 kg = 2.20 lb

Mass = 8 lb × (1 kg/2.20 lb)

         = 3.64 kg

(b) Calculate the hourly volume

V = 3.64 kg × (2 mL/1 kg)

  = 7.27 mL

(c) Calculate the daily volume

V = 24 h × (7.27 mL/1 h)

  = 175 mL

evablogger [386]

Answer:

(155.301 ; 159.299)

Step-by-step explanation:

Xbar = 157.3

Sample size, n = 234

Population standard deviation, σ = 15.6

The confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * σ/√n

Zcritical at 95% = 1.96

Standard Error = 1.96 * (15.6/√234) = 1.999

Lower boundary : 157.3 - 1.999 = 155.301

Upper boundary : 157.3 + 1.999 = 159.299

(155.301 ; 159.299)
