H(t)=-16t^2+24t+40.0

TEA [102]

Answer:

t = -1 or 5/2

Step-by-step explanation:

To find t; we equate H(t) = 0

-16t^2+24t+40.0= 0

dividing through by 8 we have ;

-16t^2 / 8+ 24t/8+40.0/8=0

-2t^2 + 3t + 5=0

-2t^2 + 5t -2t + 5=0

By factorisation;

t(-2t + 5) +1 (-2t + 5)=0

This means;

(t + 1)(-2t +5)= 0

t + 1 = 0 or -2t + 5 = 0;

t= -1 ; -2t = -5

2t = 5

t = 5/2;

Hence t = -1 or 5/2

A bicyclist travels 13 km at a speed of 20 km/hr. how long does it take her to travel this distance?

aliina [53]

Answer:

${ \tt{time = \frac{distance}{time} }} \\$

speed is 20 km/hr
distance is 13 km

${ \tt{time = \frac{13}{20} }} \\ \\ { \boxed{ \tt{ \: time = 0.65 \: hours}}}$

t the Fidelity Credit Union, a mean of 5.8 customers arrive hourly at the drive-through window. What is the probability that, in

zhuklara [117]

Answer:

0.5217

Step-by-step explanation:

Given that:

mean $\mu$ = 5.8

Using Poisson Probability formula:

$P(X=x) = \frac{ (e^{- \mu} * {\mu^x) }}{x!}$

$P(X>5.8)=1-P(X \leq5)$

$= 1-[P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)]$

$= 1 -[\frac{(e^{-5.8}*5.8^0) }{ 0! } + \frac{(e^{-5.8}*5.8^1) }{ 1! } +\frac{(e^{-5.8}*5.8^2) }{ 2! } +\frac{(e^{-5.8}*5.8^3) }{ 3! } +\frac{(e^{-5.8}*5.8^4) }{ 4! } +\frac{(e^{-5.8}*5.8^5) }{ 5! } ]$

$=1-(0.003+0.0176+0.0509+0.0985+0.1428+0.1656)$

$=1-0.4783$

$=0.5217$

∴ the probability that, in any hour, more than 5 customers will arrive =0.5217
