Question 13

kicyunya [14]

Answer:

The c intercept is 42

The t intercepts are: 6, -1 and 7

Step-by-step explanation:

Given

$c(t) = (t - 6)(t +1)(t-7)$

Solving (a): The c intercept

Simply set t to 0

$c(t) = (t - 6)(t +1)(t-7)$

$c(0) = (0 - 6)(0 +1)(0-7)$

$c(0) = (- 6)(1)(-7)$

$c(0) = 42$

Solving (b): The t intercept

Simply set c(t) to 0

$c(t) = (t - 6)(t +1)(t-7)$

$(t - 6)(t +1)(t-7) = 0$

Split

$t - 6= 0,\ \ t +1= 0,\ \ t-7 = 0$

Solve for t

$t = 6,\ \ t =-1,\ \ t=7$

(6h + 8) - (3h + 2) = 15<br> PLEASE HELP I ALSO NEED TO SHOW WORK

Anestetic [448]

Answer:

$h=3$

Step-by-step explanation:

So we have the equation:

$(6h+8)-(3h+2)=15$

First, let's distribute the negative:

$(6h+8)+(-3h-2)=15$

Combine like terms:

$(6h-3h)+(8-2)=15$

Subtract or add:

$3h+6=15$

Subtract 6 from both sides:

$3h=9$

Divide both sides by 3:

$h=3$

And we're done!
