Answers:                                                      ( '/' means divides by)

Q4 is 720miles

mph = 240

3hrs = 240 x 3

Q5 is 31.5mph

2 hrs = 65miles

1mile = 65/2

Q6 is 4 hours

20miles in 1hour

80 miles = 80/20

Q7 is 3cm

30secs = 0.5cm

60sec(1min) = 60 x 0.5

Q8 is 15km per hour

5hrs = 75km

1hr = 75/5

Q9 is 7hrs 30mins

20miles per hour meaning 1 hour

150miles = 150/20

Q10 is 165miles

distance between 4pm and 7pm is 3 hours

55(mph) x 3

Q11 is 9km per hour

210km = 30 mins(1/2hour)

1 min = 210/30

Q12 is 2hrs 30mins

2miles = 1hour

5miles = 5/2

What are the domain and range of the function mc013-1
lozanna [386]

The domain and range of the function are:

<h3>How to determine the domain of the function?</h3>

In this exercise, you're given the following function f(x) = 5ˣ ⁻ ³ + 1. Next, we would equate the function to zero (0) to determine its domain as follows:

0 = 5ˣ ⁻ ³ + 1.

-1 = 5ˣ ⁻ ³

-(5⁰) = 5ˣ ⁻ ³

-0 = x - 3

x = 3.

Therefore, the domain are all real numbers and they can be substituted for x to return a valid f(x) value.

From the graph of the given function (5ˣ ⁻ ³ + 1), we can logically deduce that the range comprises all real numbers that are greater than 1.

Exponent Laws - difference between product law and product raised to a power (with formula please)
enyata [817]

Answer:

Exponent laws:

1. Product law

x^{a}\times x^{b}\times x^{c}=x^{a+b+c}

In product law if bases are same then we add their respective powers.But if bases are different we can't add their powers.

x=base, a,b,c=exponent

If x=2 and a=3, b=5 , and c=10, then

2^{3}\times2^{5}\times2^{10}=2^{3+5+10}=2^{18}

2.Product raised to a power

1. [x^{a}]^{c}=x^{ac}

2. [x^{a}\times x^{b}]^{c}=[x^{a+b}]^{c}=x^{ac+bc}

If product is raised to a certain power , keeping the base same , we just multiply the powers.for example

[2^{3}]^{4}=2^{3\times4}=2^{12} and

[2^{3}\times3^{2}]^{2}=[2^{3}]^2 \times[3^{2}]^{2}=2^{6}\times3^{4}

[2^{3}\times2^{2}]^{2}=[2^{3+2}]^{2}=[2^{5}]^{2}=2^{10}
