Find the duration
----------------------------------------------------------------------------------------------
Time : 9:00am to 10:15am
Duration: 1hour 15 mins or 1.25hours

----------------------------------------------------------------------------------------------
Find difference in distance travelled between the two cyclists.
----------------------------------------------------------------------------------------------
Difference in speed = 6km/h
1 hour = 6 km
1.25 hours = 7.5km

----------------------------------------------------------------------------------------------
Find the distance the cyclist traveled
----------------------------------------------------------------------------------------------
42.5 - 7.5 = 35km
35km ÷ 2 = 17.5km

The slower cyclist traveled 17.5 km in the 1.25 hours

17.5 + 7.5 = 25 km

The faster cyclist traveled 25km in the 1.25 hours

----------------------------------------------------------------------------------------------
Find the speed of the slower cyclist
----------------------------------------------------------------------------------------------
1.25 hour = 17.5 km
1 hour = 17.25 ÷ 1.25
1 hour = 14km

The cyclist was traveling at 14km/h

----------------------------------------------------------------------------------------------
Find the speed of the faster cyclist
----------------------------------------------------------------------------------------------
1.25 hour = 25km
1 hour = 25 ÷ 1.25
1hour = 20 km

The cyclist was traveling at 20km/hour

----------------------------------------------------------------------------------------------
Answer: The speed were 14km/h and 20 km/h

Write the inverse function, <br> f^-1 (x), for the function <br> f (x) = 2x + 3

cricket20 [7]

$f(x) = 2x + 3$

$y = 2x + 3$

Subtract the sides of the equation minus 3

$y - 3 = 2x$

Divided the sides of the equation by 2

$\frac{y - 3}{2} = x \\$

So ;

${f}^{ - 1}(x) = \frac{x - 3}{2} \\$

Can anybody help me with 1 and 2

Anit [1.1K]

1) $x \geq 96$
2) $x\ \textless \ 38$

Here, the variable $x$ can assume any value, and usually an inequality presented like this has $x$ as a stand-in for all real numbers. If we really wanted to make that fact clear, we could write the two inequalities like this:

$x \geq 96, x\in\mathbb{R}\\ x\ \textless \ 38, x\in\mathbb{R}$

Formally, you'd read $x\in\mathbb{R}$ as " $x$ is an element of the set of real numbers," which is a fancy way of saying that $x$ can be any real number.

Answer:

See proof below

Step-by-step explanation:

We have to verify that if we substitute $a_n=4^n+2(-1)^n$ in the equation $a_n=3a_{n-1}+4a_{n-2}$ the equality is true.
