a cyclist bikes a certain distance in 45 minutes , write an equation that shows the relationship between speed,s, and time,t, wh

denis23 [38]

An equation that shows the relationship between speed and time is $Speed = \frac{100}{45}$

<u>Given the following data:</u>

Distance = 100 miles.

Time = 45 minutes.

To write an equation that shows the relationship between speed and time:

<h3>What is speed?</h3>

Speed can be defined as the distance covered by a physical object per unit of time. Thus, the cyclist's speed can be measured as miles per minutes.

Mathematically, speed is given by this formula;

$Speed = \frac{distance}{time}$

Substituting the given parameters into the formula, we have;

$Speed = \frac{100}{45}$

QF Q6.) Find the function for a.

irakobra [83]

The function for a is (f o g) (x) = 8x^2-10.

Explanation

=========================
$f(x)=2x-4, g(x)=4x^2-3, (f o g)=f(g(x))$

I already knew that the g of x is equal to $4x^2-3$ so I substitute inside of the g of x

$g(x)=4x^2-3$ =======> $f(x)=4x^2-3$ =============> $2(4x^2-3)-4$

simplify it

$2(4x^2-3)-4$ =======> $8x^2-6-4$ =========> $8x^2-10$

$(f o g) = 8x^2-10$

A square board was attached to a wall. The board was divided by four squares and each square was colored either black or white.

PtichkaEL [24]

Answer:

24 combinations

Step-by-step explanation:

For this problem, you use factorials. Factorials are when you multiply every number below it except zero. So like the factorial of 3 or 3! is 3*2*1 is 6.

Factorials are used to figure out how many combinations there are of something. So for you, we have 4 different quadrants so we write that as 4! (! is the sign for factorials.)

By the way, welcome to brainly.
