Answer:
f(29) = - [tex]\frac{9}{290}[/tex]
Step-by-step explanation:
Step 1: substitute f(29) into the equation.
f(29) = 2(29 - 20)²⁻³
29 replaces x.
Step 2: simplify the exponent
f(29) = 2(29 - 20)⁻¹
2-3 is -1, so the exponent is -1
Step 3: distribute the exponent to the parentheses
f(29) = 2([tex]\frac{1}{29}[/tex] - [tex]\frac{1}{20}[/tex])
Since the exponent is a negative one, basically make it a fraction with the base as the denominator and the exponent as a numerator. I don't know too much about negative exponents, but this is how to factor in a -1.
Step 4: Distribute.
f(29) = [tex]\frac{2}{29} -\frac{2}{20}[/tex]
Step 5: Simplify before finding a common denominator (2/20 cancels out)
f(29) = 2/29 - 1/10
Step 6: Find a common denominator (290)
f(29) = [tex]\frac{20}{290}[/tex] - [tex]\frac{29}{290}[/tex]
Step 7: Simplify
f(29) = - [tex]\frac{9}{290}[/tex]
TBH I'm not sure this is correct, but I hope this helps =)

In August 2008, Eddie hired a car in Italy. The cost of hiring the car was £620
The exchange rate was £1 = €1.25
Work out the cost of hiring the car in euros (€).
Answer:
The answer is £775 for hiring a car
The required answer would be the cost of hiring the car in euros is €775.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
In August 2008, Eddie hired a car in Italy. The cost of hiring the car was £620
The exchange rate was £1 = €1.25
We have to determine the cost of hiring the car in euros (€).
According to the given question,
For the required solution, we have to multiply the exchange rate by the cost of hiring the car
The cost of hiring the car in euros (€) = 620 × exchange rate
The cost of hiring the car in euros (€) = 620 × €1.25
Apply the multiplication operation to get
The cost of hiring the car in euros (€) = €775
Therefore, the required answer would be the cost of hiring the car in euros is €775.

The graph below shows the relationship between time and distance traveled
by a race car moving at a constant rate and at its maximum speed. How long
did it take the race car to travel 480 miles?

0.5 1.5 2.5 3.5 4.5 5.5 6.5
Time (hours)
Answer:
2.4 hours
Step-by-step explanation:
The graph is a straight line graph. A straight line graph is used to represent a linear equation. A linear equation is represented by the equation: y = mx + c, where y is the dependent variable, x is the independent variable, m is the slope (rate of change) and c is the intercept.
A line passing through the point [tex](x_1,y_1)\ and\ (x_2,y_2)\[/tex] can be represented by the equation:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Let y represent the distance in miles and x represent the time in hours. From the graph, the line pass through (0.5, 100) and (3.5, 700). Hence using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{700-100}{3.5-0.5} (x-0.5)\\\\y-100=200(x-0.5)\\\\y-100=200x-100\\\\y=200x-100+100\\\\y=200x\\\\To\ travel\ 480 \ miles,we\ substitute\ y=480\ and\ find\ x\\\\480=200x\\\\x=480/200\\\\x=2.4\ hours[/tex]

The length of the Amazon River in South America is 6,400 kilometers. What is the length written in scientific notation?
6.4 x 102 km
64 x 102 km
6.4 x 103 km
6.4 x 105 km
Answer:
[tex] 6.4 * 10^{3} km[/tex]
Step-by-step explanation:
Scientific notation can be defined as a way of expressing and writing a very small or large real number in decimal form. Generally, to use the scientific notation, we will multiply the real number by a power of 10.
Given that the length of Amazon River is 6,400 kilometers.
[tex] \frac{6400}{1000} = 6.4[/tex]
[tex] 1000 = 10^{3}[/tex]
Therefore,
6, 400 kilometers = 6.4 × 10³ kilometers.

2x + 1=4x-3 solve for x
Answer:
x = 2
Step-by-step explanation:
To start, you want to isolate x.
To do so, get all the x terms to one side.
2x + 1 = 4x - 3
Subtract -4x on both sides.
-2x + 1 = -3
Then, subtract 1 on both sides.
-2x = -4
Finally, divide -2 on both sides.
x = 2

The equation y=-2/3x-6 in standard form
The equation in the standard from is 2x + 3y = -18.
What is the linear equation?The linear equation is the algebraic form of equation whose variable has the exponent of one. It is the combination of two variables and a constant value present in them.
For the given situation,
The equation is y = -2/3 x - 6
The standard form of linear equation is Ax +By = C,
where A,B,C are numbers and x,y are intercepts.
⇒ [tex]y=\frac{-2}{3}x -6[/tex]
Taking LCM on RHS,
⇒ [tex]y=\frac{-2x-18}{3}[/tex]
⇒ [tex]3y=-2x-18[/tex]
Rearrange the equation in the standard from,
⇒ [tex]2x+3y=-18[/tex]
Hence we can conclude that the equation in the standard from is 2x + 3y = -18.
