Using an exponential function, it is found that it's annual growth rate is of 4%.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, the card appreciates exponentially in value by 50% over 10 years, hence:
A(10) = 1.5A(0).
Thus:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]1.5A(0) = A(0)(1 + r)^{10}[/tex]
[tex](1 + r)^{10} = 1.5[/tex]
[tex]\sqrt[10]{(1 + r)^{10}} = \sqrt[10]{1.5}[/tex]
1 + r = 1.04.
r = 0.04.
0.04 x 100% = 4%.
It's annual growth rate is of 4%.

For the function y = x -2, make a table of ordered pairs and graph the function on a coordinate plane.
Answer:
Step-by-step explanation:
Start by plugging in the x values -2, -1, 0, 1, and 2 into the equation to receive the y values.
For example, the first point on the table would be y=(-2)-2, or (-2, -4). Continue plugging in the points for all the points on the table
Omar thinks you should sell sundae cups and raspberry ripple cones. He recommends that the costs to you for frozen treats be no more than $450. Based on Omar's recommendation, enter an inequality that represents the
number of sundae cups, x, and the number of raspberry ripple cones, y, that will cost you no more than $450.
Considering that a sundae cone costs $5 and a raspberry ripple cone $7, the inequality is:
[tex]5x + 7y \leq 450[/tex]
What is the inequality that models this situation?The total price can be no more than $450, hence:
[tex]T \leq 450[/tex]
To find the total price, we need the price of each a sundae cone and a raspberry ripple cone, which are not given. Hence, considering that a sundae cone costs $5 and a raspberry ripple cone $7, the total price is given by:
T = 5x + 7y
Hence, the inequality is:

Answer:
3/4 lbs.
Step-by-step explanation:
In order to find how much more the heavier boxes weigh than the lighter boxes, we have to subtract the lighter box weight from the largest box weight.
Lighter box weight = 4 1/2
Heavier box weight = 5 1/4
Now we can find their difference:
The heavier box weight - lighter box weight = 5 1/4 - 4 1/2 = 21/4 - 9/2 = 21/4 - 18/4 = 3/4.
The heavier boxes weigh 3/4 lbs. more than the lighter boxes.
Answer:
3/4 lbs
Step-by-step explanation:
The heavier box weight - lighter box weight = 5 1/4 - 4 1/2 = 21/4 - 9/2 = 21/4 - 18/4 = 3/4.
The difference is:
The heavier boxes weigh 3/4 lbs. more than the lighter boxes.

2/5x + 25= 4/5x + 30
Answer:
x = 12 1/2
Step-by-step explanation:
Combine like terms, as follows: 25 - 30 = (4/5)x - (2/5)x, or
5 = (2/5)x
Multiplying both sides by (5/2) 'solves' this equation for x:
(5/2)(5) = (5/2)(2/5)x => (25/2) = x
Then x =25/2 or x = 12.5 or x = 12 1/2

Answer:
x = 1Step-by-step explanation:
In the question we have given an equation that is x / 5 + ( x - 1 ) / 3 = 1 / 5 . And we are asking to solve the equation that means we have to find the value of x.
Solution : -
[tex] \longmapsto \qquad \dfrac{x}{5} + \dfrac{(x - 1)}{3} = \dfrac{1}{5} [/tex]
Step 1 : Bye taking L.C.M solving left side :
[tex] \longmapsto \qquad \dfrac{3x + 5(x - 1)}{15} = \dfrac{1}{5} [/tex]
On further calculations, We get :
[tex] \longmapsto \qquad \dfrac{3x + 5x - 5}{15} = \dfrac{1}{5} [/tex]
[tex] \longmapsto \qquad \dfrac{8x - 5}{15} = \dfrac{1}{5} [/tex]
Step 2 : Multiplying 15 on both sides :
[tex] \longmapsto \qquad \dfrac{8x - 5}{ \cancel{15}} \times \cancel{15 } = \dfrac{1}{ \cancel{5}} \times \cancel{15}[/tex]
On further calculations, We get :
[tex] \longmapsto \qquad 8x - 5 = 3[/tex]
Step 3 : Adding 5 on both sides :
[tex] \longmapsto \qquad8x - \cancel{5} + \cancel{ 5} = 3 + 5[/tex]
On further calculations, We get :
[tex] \longmapsto \qquad8x = 8[/tex]
Step 4 : Dividing with 8 on both sides :
[tex] \longmapsto \qquad \dfrac{ \cancel{8}x}{ \cancel{8}} = \cancel{\dfrac{8}{8} }[/tex]
On further calculations, We get :
[tex] \longmapsto \qquad \blue{\underline{\blue{\boxed{ \frak{x = 1}}}}}[/tex]
Henceforth, value of x is 1 .Verifying : -
We are verifying our answer by substituting value of x in the given equation . So ,
x / 5 + ( x - 1 ) / 3 = 1 / 51 / 5 + (1 - 1 ) / 3 = 1 / 51 / 5 + 0 / 3 = 1 / 5 (0 / 3 is equal to 0) 1 / 5 + 0 = 1 / 51 / 5 = 1 / 5 L.H.S = R.H.SHence , Verified .Therefore, our solution is correct .
