Answer:
This is a simple interest, as the amount earned each year is constant
Step-by-step explanation:
Using compound interest, it is found that the constant percent rate of change is of 4%.
--------------------
The formula for an amount of money invested into compound interest is given by:
[tex]A(t) = A(0)(1+r)^t[/tex]
In which:
A(t) is the amount after t years.A(0) is the initial amount.r is the constant percent rate of change.t is the time.--------------------
The function is:
[tex]g(x) = 300(1.04)^x[/tex]
Thus, for the constant percent rate of change:
[tex]1 + r = 1.04[/tex]
[tex]r = 1.04 - 1 = 0.04[/tex]
[tex]0.04 \times 100\% = 4\%[/tex]
The constant percent rate of change is of 4%.

The cost of a camp is $300 for the first week and $125 for each week beyond the first. The total cost can be modeled by the expression 300 + 125(x – 1). What does (x – 1) represent?
x - 1 is the total number of weeks minus the first
Answer: x-1 is number of weeks-1st week
Step-by-step explanation:
x represents the number of weeks bring the first.
-1 is to remove the first week that costs $300
Re-write the equation 3 x minus y = 4 in slope-intercept form.
a.
y = 3 x minus 4

Answer:
a-4,8+_84(4+4(*:84
dirkrk
The component form of the vector that translates will be 11i - 17j.
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
The translation does not change the shape and size of the geometry. But changes the location.
The point A(-4, 8) is translated to the point A'(7, -9). Then the rule of the transformation is given as,
(7, - 9) = (- 4 + x, 8 + y)
Compare the abscissa, then we have
7 = - 4 + x
x = 7 + 4
x = 11
Compare the ordinate, then we have
y + 8 = - 9
y = - 8 - 9
y = - 17
The component form of the vector that translates will be 11i - 17j.

Answer:
y = 14/3 and 2
x = -13/3 and 1
(-13/3, 14/3) and (1, 2)
Step-by-step explanation:
[tex]x + 2y = 5 - - - (a) \\ {x}^{2} - {y}^{2} = - 3 - - - (b)[/tex]
for equation (a)
make x the subject of the formular:
[tex]x = 5 - 2y - - - (c)[/tex]
for equation (b)
[tex] {x}^{2} - {y}^{2} = - 3[/tex]
substitute for x as 5 - 2y in equation (b):
[tex] {(5 - 2y)}^{2} - {y}^{2} = - 3 \\ (25 - 20y + 4 {y}^{2} ) - {y}^{2} = - 3 \\ 25 - 20y + 3 {y}^{2} = - 3 \\ {3y}^{2} - 20y + 28 = 0 \\ (3y - 14)(y - 2) = 0[/tex]
therefore,
[tex]y = \frac{14}{3} \: \: and \: \: 2[/tex]
substitute for all values of y in equation (c):
for y = 14/3:
[tex]x = 5 - 2( \frac{14}{3} ) \\ \\ x = 5 - \frac{28}{3} \\ \\ x = - \frac{13}{3} [/tex]
for y = 2:
[tex]x = 5 - 2(2) \\ x = 5 - 4 \\ x = 1[/tex]
Answer:
(1, 2)
(-13/3, 14/3).
Step-by-step explanation:
x + 2y = 5
x² - y² = -3
From the first equation x = 5 - 2y
Substitute for y in the second equation:
(5 - 2y)^2 - y^2 = -3
25 + 4y^2 - 20y - y^2 = -3
3y^2 - 20y + 28 = 0
Factoring:-
(3y - 14(y - 2) = 0
y = 2, 14/3.
So when y = 2, x = 5 - 2(2) = 1.
When y = 14/3, x = 5 - 2(14/3) = -13/3.
Checking the results in the second equation:
(1, 2):-
1^2 - 2^2 = -3 Correct.
(-13/3, 14/3):-
(-13/3)^2 - (14/3)^2 = -3 Correct.
