(c) One lorry travels from your town to another town. The lorry reaches a top speed
of 90 km/h, but its average speed between the towns is only 66 km/h.
Why is the average speed less than the top speed?

Answer:

c: f(x) = 2(4^x)

Step-by-step explanation:

the table shows that the function is exponential rather than linear.

The best that represents the function shown in the table;

c: f(x) = 2(4^x)

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical.

Thus, the table shows that the function is exponential rather than linear.

We are given the table through which we have to make a function.

The function becomes as;

[tex]f(x) = 2(4^x)[/tex]

This function shows exponential rather than linear.

Step-by-step explanation:

-26=3v+1

divide by 3 both sides

-9=v

This type of graph is called a segment.

To write the solution set which represents the graph

of a segment, read the segment from left to right.

If you take a look at the segment shown here, we would start with the endpoint on the left which is a -4, our variable x would be in the middle, and we would finish things off with the endpoint on the right, which is 5.

Since we have an open dot at -4, we use a less than sign between the -4 and the x and since we have a closed dot at 5, we use a less tan or equal to sign between the x and the 5.

It's important to understand that when representing a segment by reading it from left to right, you will only use "less than" or "less than or equal to" between the parts, never "greater than" or "greater than or equal to."

So the solution for this graph is read {x: -4 < x ≤ 5}.

Answer:

d = 17

Step-by-step explanation:

The given arithmetic sequence is :

31, 48, 65, 82, ...

We need to find the common difference for this sequence.

First term, a₁ = 31

Second term, a₂ = 48

Common difference = a₂-a₁

= 48-31

= 17

So, the common difference for this arithmetic sequence is equal to 17.

Step-by-step explanation:

Given

6x^4 - 30x³ - 84x²

= 6x² ( x² - 5x - 14 )

= 6x² ( x² - ( 7 - 2 ) x - 14 )

= 6x² ( x² - 7x + 2x - 14 )

= 6x² {x(x - 7) + 2 ( x - 7)}

= 6x² ( x - 7) (x +2 )

Step-by-step explanation:

standard form

 c represents y intercept

m represents slope or gradient

y= 3x-2

The slope is 3 and the y intercept in -2

Answer:

yes

Step-by-step explanation:

If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y

If you are multipling the answer will be y^10  because 10 plus 10 is 20 and you keep the base which is y

All we have to do to simplify this expression is multiply 8 by 12 and a:

8(12+a)

96+8a

That's our final answer.

[tex]\huge\mathfrak{LoveLastsAllEternity}[/tex]

The distributive property is defined as:

a x (b + c) = a x b + a x c

a x (b - c) = a x b - a x c

The final value of the expression 8 x (12 + a) after simplification using the distributive property is 96 + 8a.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

8(12 + a)

We will apply the distributive property.

The distributive property is defined as:

a x (b + c) = a x b + a x c

a x (b - c) = a x b - a x c

Now,

8 x (12 + a ) is in the form of a x (b + c)

So,

8 x (12 + a)

= 8 x 12 + 8 x a

= 96 + 8a

Thus,

The final value of the expression 8 x (12 + a) after simplification using the distributive property is 96 + 8a.
