<h3>Initial amount = 1</h3><h3>Rate of growth = 80 %</h3><h3>The value is 18.9 when t = 5</h3>
<em><u>Solution:</u></em>
<em><u>The given exponential function is:</u></em>
<em><u>The exponential function is given as:</u></em>
Where,
y is the future value
a is the initial value
r is the growth rate
t is the number of years
<em><u>Compare both the functions,</u></em>
a = 1
Thus growth rate is:
<em><u></u></em>
<em><u>Evaluate the function when t = 5</u></em>
Substitute t = 5 in given
Thus the value is 18.9 when t = 5
Answer:
x = 6
y = 1
Step-by-step explanation:
to solve this system of equation we say let
2x + 3y = 15 .......................... equation 1
x - 3y = 3.................................. equation 2
from equation 2
x - 3y = 3.................................. equation 2
x = 3 + 3y.................................... equation3
substitute for x in equation 1
2x + 3y = 15 .......................... equation 1
2(3+3y) + 3y = 15
6 + 6y + 3y = 15
9y = 15 -6 ................................... combining the like terms
9y = 9
divide both sides by the coefficient of y
9y/9 = 9/9
y =1
put y = 1 in equation 3
x = 3 + 3y.................................... equation3
x = 3 + 3(1)
x = 3 +3
x = 6
therefore the value of x is 6 and y is 1 respectively
The answer is 3 hope this helps pls thank me
Answer: Don't know sorry
Step-by-step explanation:
Answer: 
Step-by-step explanation:
For balancing a hanger,
The weight of both sides of the hanger must be equal,
Here, the left side weight = 24 unit,
While the right sides total weight = c + c + c + c + c + c
= 6 c
For balancing it,
⇒
Thus, in the balancing equation the value of c will be 4.
