Answer:

3 , 11, 25, 45

Diff 8 14 20

Diff 6 6

The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3

therefore 3n^2

3 11 25 45

3n^2 3 12 27 48

Remainder 0 -1 -2 -3

Difference -1 -1 -1

linear sequence with nth term -n+1

so nth term of quadratic sequence in 3n^2-n+1

Answer:

x=6 is not a solution

Step-by-step explanation:

We can substitute 6 as x to find out:

5(6-3)=6+13

first, because of PEMDAS we'll do 6-3

5(3)=6+13

multiply 5 by 3 and add 6 and 13

15=19

Since the statement is not true, that means that x=6 is not a solution

$40 per week

Step-by-step explanation:

Step one:

Given data

the initial amount is = $100

the total amount= $500

let the number of weeks be x

Step two:

The expression for the scenario is

[tex]500= 100+40x-------1[/tex]

From the expression above, the rate of the change is $40 per week.

this means that in every week the account will be increased by $40

Answer:

Q'(15, -3)

Step-by-step explanation:

Multiply the coordinates by the scale factor to get the new coordinates.

5 · 3 = 15

-1 · 3 = -3

Therefore, Q'(15, -3).

Step-by-step explanation:

a^2 +b^2 = c^2. Since 18 would be c in this equation, you just do 18 squared minus 8 squared.

Answer:

17.89 m

Step-by-step explanation:

A^2+B^2=C^2

8squared=64

18squared=256

64+256=320

320 (radical)

17.89 m

Answer:

if the sum of digits is divisible by 3 ,the number is also divisible by 3. Since 210 is divisible by 3, the given number is also divisible by 3.

Answer:

the answer is 4.5 but you cannot plant 4 and a half seeds. so the answer would be 3.

Step-by-step explanation:

Answer:

3x + 9

Step-by-step explanation:

You basically want the total amount of seeds so if he plants x in one garden and 2x + 9 in another, you add them both

x + 2x + 9

Equals 3x + 9

Answer:

28.7

Step-by-step explanation:

Diane did not choose a good model. Because the water is a projectile with a maximum height, she should use a quadratic model

Step-by-step explanation:

Here, we want to choose the correct option

As we are having a circular projection, we should be looking at having a parabolic representation i.e a model that looks like a parabola

So the correct answer in this case is that;

Answer:

It's the dot that's right in the middle of the rest, where the two lines meet.

Step-by-step explanation:

That's the equilibrium point.

The equilibrium point of the given graph is at (35, 90)

The demand curve shows the quantities of a particular good or service that buyers will be willing and able to purchase at each price during a specified period. The supply curve shows the quantities that sellers will offer for sale at each price during that same period.

Given that, the supply and demand curves for a new style of silver earrings are shown.

We need to find the equilibrium point,

We know that, On a demand and supply graph, the equilibrium point can be found where the demand and supply curves intersect. Price is on the axis on both the demand and supply curves, and quantity demanded is on the axis.

In our graph, the curves are intersecting at (35, 90)

Hence, the equilibrium point of the given graph is at (35, 90)

Answer:

the difference is 25.5

Step-by-step explanation:

34.1 - 8.6 = 25.5

[tex]42.7^{\circ}F[/tex]

Subtract the number with the smallest value from the number with the biggest value to determine the difference between two numbers.

Temperature in a town during the day [tex]=34.1^{\circ}F[/tex]

Temperature in a town during the night [tex]=-8.6^{\circ}F[/tex]
