7/9÷4/9 = 7/9*9/4cancel 9 on each side=7/4= 1 3/41. Hoang currently requires $1000 per week to maintain his lifestyle. Assuming inflation
averages 2% per year, how much will Hoang require per week to maintain his current
lifestyle in:
a. 10 years' time:
U..=1000
b. 20 years' time:
C. 30 years' time:
Using an exponential function, we have that:
a) In 10 years, the amount needed will be of $1,219 per week.
b) In 20 years, the amount needed will be of $1,486 per week.
c) In 30 years, the amount needed will be of $1,811 per week.
An increasing exponential function has the following format:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the rate of change, as a decimal.In this problem:
Currently requires $1000, thus [tex]A(0) = 1000[/tex].Inflation of 2% per year, thus [tex]r = 0.02[/tex]Then, his weekly amount needed is going to be given by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]A(t) = 1000(1 + 0.02)^t[/tex]
[tex]A(t) = 1000(1.02)^t[/tex]
Item a:
In 10 years, we have that:
[tex]A(10) = 1000(1.02)^{10} = 1219[/tex]
In 10 years, the amount needed will be of $1,219 per week.
Item b:
In 20 years, we have that:
[tex]A(20) = 1000(1.02)^{20} = 1486[/tex]
In 20 years, the amount needed will be of $1,486 per week.
Item c:
In 30 years, we have that:
[tex]A(30) = 1000(1.02)^{30} = 1811[/tex]
In 30 years, the amount needed will be of $1,811 per week.

What is the value of x which proves that the runways are parallel? What is the measure of the larger angle?
Answer:
118°
Step-by-step explanation:
When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent.
Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°.
Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.
(5x + 17) + (15x - 17) = 180
5x + 15x + 17 - 17 = 180
20x = 180
20x/20 = 180/20
x = 9°
Nkw let's substitute x = 9 into the equations
5x + 17 =
5(9) + 17 =
= 62°
15x - 17 =
15(9) - 17 =
= 118°
Both equations should add up to be 180°.
Therefore the measure of the largest angle is 118°.

A city's population in the year x = 1990 was y = 2,201,900. In 1994 the population was 2,202,100. Compute the slope of the population growth (or decline)
Answer:
Slope is 50x (50/1)
Explanation:
let m = slope
m = (y2-y1)/(x2-x)
m = (2,202,100-2,201,900)/(1994-1990)
m = 50/1
m = 50

Tom purchased international calling cards before traveling abroad. He bought a 60-minute card for $9.99, a 90-minute card for $14.29, a 100-minute card for $17.99, and a 200-minute card for $29.49. After using all of his calling cards, Tom used his mobile phone for 38 minutes at a rate of $2.99/minute.
The amount spent on calls per minute is an illustration of unit rates.
The amount spent on the 38-minute call is $113.62
The given parameters are:
[tex]\mathbf{Rate = \$2.99/minute}[/tex]
[tex]\mathbf{Time = 38\ minutes}\\[/tex]
So, the amount spent on call is:
[tex]\mathbf{Amount = Rate \times Time}[/tex]
This gives
[tex]\mathbf{Amount = \$2.99/minute \times 38\ minutes}[/tex]
Cancel out minutes
[tex]\mathbf{Amount = \$2.99 \times 38}[/tex]
[tex]\mathbf{Amount = \$113.62}[/tex]
Hence, the amount spent on the 38-minute call is $113.62

Amadou bought snacks for his team's practice. He bought a bag of chips for $1.71 and a 24-pack of juice bottles. The total cost before tax was $26.91. Write and solve an equation which can be used to determine jj, how much each bottle of juice costs.
Building and solving an equation, it is found that each bottle of juice costs $1.05.
Her total cost of $26.91 is composed by:
A bag of chips that cost $1.71.24 juice bottles, each costing j.Hence, the equation is:
[tex]1.71 + 24j = 26.91[/tex]
Solving it, we find the cost of a bottle of juice, hence:
[tex]1.71 + 24j = 26.91[/tex]
[tex]24j = 25.2[/tex]
[tex]j = \frac{25.2}{24}[/tex]
[tex]j = 1.05[/tex]
Each bottle of juice costs $1.05.

Determine the axis of symmetry of a parabola whose graph is given below. Give your answer in the form X equals H
Answer:
x = -3
Step-by-step explanation:
The axis of symmetry of a parabola, in the form of x = h is x = -3, where the value of h is -3.
A surface curve formed by the intersection of a cone and a plane parallel to a straight line is called as parabola.
An imaginary straight line that divides a shape into two identical halves is called as axis of symmetry.
In the given figure, the graph intersects the x-axis at x = -3.
So, the axis of symmetry of a parabola in the form of x is -3.
Thus, the value of h is -3.

X-(-y-z+3) remove the parentheses
Answer:
x + y + z - 3
Step-by-step explanation:
Basically, putting a negative sign before parentheses signifies that you want to flip the sign of everything within the parentheses. This can also be explained by the negative sign representing -1.
Knowing this, we can just multiply everything within by -1.
-y -> y
-z -> z
3 -> -3
We now have y + z - 3, just put this into the original expression and we have our final answer of:
x + y + z - 3
