8a^3 b^2 = 2*2*2 *a*a*a *b*b

12ab^4 = 2*2*3 *a*b*b*b*b

to find the CGF, multiply those factors both numbers have in common

GCF: 2*2 *a*b*b

CGF 4*a*b^2

4ab^2

Write the equation of the line in slope-intercept form that has a slope of 1/2

Arada [10]

Answer:

Step-by-step explanation:

m = 1/2, (18,10)

y - y = m(x-x)

y - 10 = 1/2 (x - 18)

y - 10 = 1/2x -9

y = 1/2x - 9 + 10

y = 1/2x + 1

PLEASE HELP: p(t)=1.8^t

Karo-lina-s [1.5K]

<h3>Initial amount = 1</h3><h3>Rate of growth = 80 %</h3><h3>The value is 18.9 when t = 5</h3>

Solution:

The given exponential function is:

$p(t) = 1.8^t$

The exponential function is given as:

$y = a(1+r)^t$

Where,

y is the future value

a is the initial value

r is the growth rate

t is the number of years

Compare both the functions,

a = 1

$1+r = 1.8\\\\r = 1.8 - 1\\\\r = 0.8$

Thus growth rate is:

$r = 0.8 = 0.8 \times 100 \% = 80 \%$

Evaluate the function when t = 5

Substitute t = 5 in given

$p(5) = 1.8^5\\\\p(5) = 18.89568 \approx 18.9$

Thus the value is 18.9 when t = 5

To rent a certain meeting room, a college charges a reservation fee of $49 and an additional fee of $5.40 per hour. the film clu

alisha [4.7K]

+ use t for the number of hours the meeting room is rented
+ college charges a reservation fee of $49 and an additional fee of $5.40 per hour.So we have 49+ 5.40t
+ the film club wants to spend less than $81.40 on renting the meeting room, and we need:49+ 5.40t< 81.40
or 5.40t < 81.40- 49
and 5.40t< 32.40
t< 32.40: 5.40= 5.629
So the possible amounts of time for which they could rent the meeting room 5.6 hours
