Explanation:

y=2 is a straight horizontal line through the point y=2.

As such for all x-values, the y-value will be the same which is y=2 in this case.

LOOK AT THE EQUATION !

The equation tells everything that Y depends on, and what the exact value of Y is for every possible value of all the things that it depends on.

THIS equation says: "The value of Y depends on '2'. At every moment, no matter what the value of '2' is, Y is equal to it."

The equation tells you that.

So now, we can actually tell the future ! We know that the value of '2' is always going to be TWO. If we use the powerful equation that we have, we know that Y is always going to be TWO.

Does the value of Y depend on the value of X ? If it does, then X must be there on the right side of the equation. But X is not there ! That means that X has no influence on the value of Y. Y is always 2 !

You say X=5 ? That's nice. Who cares ? ! ? It has no influence on Y . Y is ALWAYS 2 .

11. A cyclist accelerates from 0 m/s to 10 m/s in 3 seconds. What is his acceleration ? Is this acceleration higher than that of

Marat540 [252]

$a = \frac{v - u}{t}$

v = final velocity

u = initial velocity

t = time taken

the acceleration of the cyclist is

$\frac{10 - 0}{3} = 3.333333....$

approximately 3.33 m/s^2

the acceleration of the car is

$\frac{40 - 0 }{8} = 5.0$

5.0 m/s^2

$5.0 > 3.33 \\ so \: the \: answer \: is \: no$

A 73.9 kg weight-watcher wishes to climb a

Tresset [83]

The height to which the weight-watcher must climb to work off the equivalent 991 (food) Calories is 0.59 Km

<h3>How to determine the energy. </h3>

1 food calorie = 103 calories

Therefore,

991 food calories = 991 × 103

991 food calories = 102073 calories

Multiply by 4.2 to express in joule (J)

991 food calories = 102073 × 4.2

991 food calories = 428706.6 J

<h3>How to determine the height </h3>

Energy (E) = 428706.6 J
Mass (m) = 73.9 kg
Acceleration due to gravity (g) = 9.8 m/s²

Height (h) =?

E = mgh

Divide both side by mg

h = E / mg

h = 428706.6 / (73.9 × 9.8)

h = 591.95 m

Divide by 1000 to express in km

h = 591.95 / 1000

h = 0.59 Km
