Step-by-step explanation:

Answer:

Formula for area is length times width

So 2x × x = 2x^2

E. G.

2×2×2=8

And can also be written as 2^3

Meaning 2×2×2

So in this instance x × x=x^2

In front of the length x imagine a 1

So 2×1=2

Therefore 2x^2

Answer:

Area = 2x²

Step-by-step explanation:

Area = L x W

L = 2x

W=x

 x*2 =2x

x*x =x²

 Area = 2x²

Answer:

10 is B. 9 is 28.8

Step-by-step explanation:

Answer:

First term: 6

Common difference:  15/4

Step-by-step explanation:

General form of arithmetic progression:

[tex]a_n=a+(n-1)d[/tex]

(where [tex]a[/tex] is the initial term and [tex]d[/tex] is the common difference between terms)

Question (a)

[tex]\implies a_3=a+(3-1)d=a+2d[/tex]

[tex]\implies a_9=a+(9-1)d=a+8d[/tex]

[tex]\implies a_{25}=a+(25-1)d=a+24d[/tex]

Question (b)

General form of a geometric progression:  [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

Therefore, the first three terms of a geometric series are:

[tex]a_1=ar^0=a[/tex]

[tex]a_2=ar^1=ar[/tex]

[tex]a_3=ar^2[/tex]

To find the common ratio:

[tex]r=\dfrac{ar^2}{ar}=\dfrac{ar}{a} \implies \dfrac{a_3}{a_2}=\dfrac{a_2}{a_1}[/tex]

If the 3rd 9th and 25th terms of an arithmetic progression form the first three consecutive terms of a geometric series, then inputting these into the above formula for r:

[tex]\implies \dfrac{a+24d}{a+8d}=\dfrac{a+8d}{a+2d}[/tex]

[tex]\implies (a+24d)(a+2d)=(a+8d)(a+8d)[/tex]

[tex]\implies a^2+26ad+48d^2=a^2+16ad+64d^2[/tex]

[tex]\implies 10ad=16d^2[/tex]

[tex]\implies 10a=16d[/tex]

The 6th and 7th terms of the arithmetic progression are:

[tex]a_6=a+5d[/tex]

[tex]a_7=a+6d[/tex]

If the sum of the 7th and twice the 6th term of the arithmetic progression is 78, then:

[tex]\implies a_7+2(a_6)=78[/tex]

[tex]\implies (a+6d)+2(a+5d)=78[/tex]

[tex]\implies 3a+16d=78[/tex]

Substituting  [tex]10a=16d[/tex]  into  [tex]3a+16d=78[/tex]  and solving for a:

[tex]\implies 3a+10a=78[/tex]

[tex]\implies 13a=78[/tex]

[tex]\implies a=6[/tex]

Substituting [tex]a=6[/tex] into  [tex]3a+16d=78[/tex]  and solving for d:

[tex]\implies 3(6)+16d=78[/tex]

[tex]\implies 16d=60[/tex]

[tex]\implies d=\dfrac{15}{4}[/tex]

Answer:

£40000

Step-by-step explanation:

→ Set up an equation

x × 0.6 = 24000

→ Divide both sides by 0.6

x = 24000 ÷ 0.6 = 40000

The percentage shows that number of people that were surveyed is 866.

Let the number of people surveyed be x.

Therefore, from the question given and the percentage, the calculation goes thus:

82% × x = 710

0.82x = 710

x = 710/0.82

x = 866

The number of people surveyed is 866.

Answer:

Distributitive Property

Step-by-step explanation:

The correct justification for the first step in solving the provided equation is that the first step should be distributive Property

Property of equality says that by performing any mathematical operation, of both sides of a expression does not change the original value of the equation.

The equation given in the problem is,

[tex]3(x - 4) + 1 = 12x[/tex]

To solve the above equation, we need to open the brackets of the equation. To do this, we need to use the distributive property of the equality.

This can be done by multiplying the number 3 inside the bracket (x-4). This operation simplify the equation, to solve it further. Therefore,

[tex]3x - 3\times4 + 1 = 12x\\3x - 12 + 1 = 12x[/tex]

Hence, the correct justification for the first step in solving the provided equation is that the first step should be distributive Property.

b. 3/4 = .75 because 3 divided by 4 = .75 so .75 * 24 = 18

The total amount of the initial deposit of Natalie account when she opened the account is $225.

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.

The formula for the simple interest can be given as,

[tex]I=\dfrac{Prt}{100}[/tex]

Here, (I) is the interest amount earned on the principal amount of (P) with the rate of (r) in the time period of (t).

Natalie opened a bank account that earns 2. 5% simple interest.

Natalie's account earned $180 over the period of 10 years. The interest amount she earned is,

[tex]I=\dfrac{Prt}{100}\\I=\dfrac{180\times2.5\times10}{100}\\I=45[/tex]

The interest amount she earned is $45 and the initial amount was $180. Thus, the total amount,

[tex]A=P+I\\A=180+45\\A=225[/tex]

Thus, the total amount of the initial deposit of Natalie account when she opened the account is $225.

f(x)=-4x-1

Answer:

Step-by-step explanation:

This is called a 'System of equations'.

Say that you have these two expressions, and the unknown is "b".

5b = y

4b+2 = y

Now we can solve two ways; graph it or solve it.

Solving it, we can see that they both equal y, so:

5b=4b+2

move 4b to the left side by subtraction:

(5b-4b) =2

b = 2

let's see what y equals when b = 2

5 * 2 = y

10 = y

Graphing it we see they intersect, or solve at

(2,10) or b=2, y=10

By hit and trial of each option and also by graph, solutions to f(x) = 3ˣ and  g(x)=2x-1 will be 0 and 1.

given functions are,

[tex]f(x) = 3^x\\\\g(x) = 2x+1[/tex]

let us put x=0

f(0) = 1

g(0) = 1

f(0)=g(0)=1

so 0 will be a solution.

let us put x=1

f(1)= 3

g(1) = 3

f(1)=g(1)=3

so 1 will be also a solution

let us put x=2

f(2) = 9

g(2) = 5

f(2)≠g(2)

so 2 will not be solution.

x=-2 and x=-1 clearly will not be solution because,

g(-2) = negative value but f(x) cannot be negative, being an exponential function.

Any function in form f(x)= pˣ, where p≥1, is called an exponential function.

therefore, solutions to f(x) = g(x) will be 0 and 1.

Answer:

The vertex form would be  y =  (x+2)^2

The factored form would be y = (x-2)(x-2)

The standard form would be y = x^2-4x+4

Step-by-step explanation:

To find this, you know that the vertex is 2 left from the center, so you have h = -2, and k = 0 since it isnt shifted up. The graph isn't shifted up either, so a=1.

The vertex form would be:  y = a(x-h)^2+k

                                                 =  (x+2)^2

The factored form would be y = (x-2)(x-2)

The standard form would be y = x^2-4x+4
