Answer:

-79.8

Step-by-step explanation:

The change can be found by subracting the ending distance from the beginning distance.

In this case, its 200.6-120.8= 79.8

It is negative because the distance in the end became lower than the beginning distance.

The value of NO such that R is at the centroid of the triangle will be 57.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the b.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

As per the given triangle,

The R is centroid thus NR/RO = 2/1

As per the given NR = 38

38/RO = 2/1

RO = 38/2 = 19

Thus, NO = NR + RO = 38 + 19 = 57

Hence "The value of NO such that R is at the centroid of the triangle will be 57".

Step-by-step explanation:

yes, in a similar way as division is a shortcut for repeated subtraction.

you do know, that you normally have to add the points win in a game, right ?

so, your score grows by 200 points each time you score.

that means

200

200

200

...

200

what do you think you do to get the total ? you add all the points.

you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.

but you did not have 200 hits, you only got 12 hits.

so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).

and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.

that is how multiplication works and helps with additions.

Step-by-step explanation:

Emily buys 3 pencils for 51p

Work out the price of 4 pencils.

51 : 3 * 4 = 68p

Answer:

68

Step-by-step explanation:

We can write a ratio to solve

3 pencils      4 pencils

------------- = -------------

51 p                x

Using cross products

3x = 51*4

3x = 204

Divide by 3

3x/3 = 204/3

x = 68

because that property, that you presented, did not exist.

Answer:  SLOPE=-170, Y-INTERCEPT = 1020

Step-by-step explanation:

Calculate the slope:  Take any two points and find the changes in x and y:

I'll use (4, 340) and (6, 0):

Change in y (the rise) is (0 - 340) = -340.

The change in x is (6-4) = 2

The slope is the rise (y) over the run (x):  -340/2 or -170.

The y-intercept is the value of y when x=0.  The f=-data provided has a value for y at x=0:  (0,1020).  So the interecpt is 1020.

Explanation:

Substitute the value of the variable into the expression and simplify.

Step-by-step explanation:

The function f(x)=e⁴⁻ˣ   is differentiable for all values of x over the interval (-5,5)

A differential equation is an equation that contains one or more functions with its derivatives.

There are a few ways to tell- the easiest would be to graph it out- and ask yourself a few key questions

Function is continuous over the interval. If it is continuous it is probably differentiable

Does the function have any sharp turns in the interval. A sharp turn means it is not differentiable at that point and therefore not differentiable on the entire interval

f(x)=e⁴⁻ˣ is differentiable over (-5, 5)This is because the exponential function is continuous and infinitely differentiable

Hence, the function f(x)=e⁴⁻ˣ   is differentiable for all values of x over the interval (-5,5)

Answer:

seems like its so hard bye

Irma has a total point of -8 now.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given that, Irma is just learning to play the Happy Fairies video game.

In the game, based on the taking care of fairies, players gain and lose points.

Initial point Irma had = -5 points

Fairy fell over in the wind and she got -3 points.

Final point = -5 + -3

                 = -5 - 3

                 = -8

Hence the total points now is -8.

Answer: y = -5/2 -17

Step-by-step explanation: First put the equation in point slope form

Y-y1 = m(x-x1)

y + 2 = -5/2(x+6) then simplify to slope int. form

Y= mx + b

Y = -5/2x-17

Answer:

y = (-5/2)x - 17

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

y = mx + b

Slope = -5/2

y = (-5/2)x + b        [tex]\longmapsto\\[/tex]         Input x and y values from given point

-2 = (-5/2)-6 + b

-2 = (-5 * -6)/(2) + b

-2 = 30/2 + b

-2 = 15 + b

b = -2 - 15

b = -17

y = mx + b

m = -5/2

b = -17

y = (-5/2)x - 17

So thinking about it technically you can have 4 of each number in a different spot not their own, and 4x4x4x4 = 256
