Answer:

transformation across the x axis

Answer:

Reflection over the X-axis

Step-by-step explanation:

That's the only thing I can think of. Can you list the choices, though? It could be a reflection followed by a translation...

Answer:

A)    A(t) = 5000(1 + 0.012)t

B)    A(t) = 106260

Step-by-step explanation:

A) 5000 is the initial amount, 1 + 0.012 is the interest rate, and t represents the years.

B) When we plug 21 into the equation,  we get 106260.

Answer:

X= 17.5

Step-by-step explanation:

the outside of the triangle always = 180

so you need to add up all the sides and equal to 180

5x+35+x+5+2x=180

add like terms

8x+40=180

get the x alone

x=17.5

Answer:

9.091(1.1^n)

Step-by-step explanation:

Given the height of a tree for the past 4 years given by the sequence;

10ft, 11ft, 12.1ft, 13.31ft...

We can see that the sequence is in geometric progression since they have a common ratio;

The nth term of a geometric progression is expressed as;

Tn = ar^n-1

a is the first term

r is the common ratio

Given

a = 10

r = 11/10 = 21.1/11 = 13.31/12.1 = 1.1

Substitute into the formula;

Tn = 10(1.1)^{n-1}

Tn = 10(1.1^n)/1.1

Tn = 9.091(1.1^n)

Hence the recursive formula for the height of the tree is expressed as  9.091(1.1^n) where n is the total number of tree.

The required value of the trigonometric operator tan(π/12) = 2 -√3. None of them is correct.

These are the equation that contains trigonometric operators such as sin, cos.. etc. In algebraic operation.

Let,

= [tex]tan(\pi /12) = tan((3-2)\pi /12)[/tex]
[tex]= tan[(3\pi -2\pi )/12]\\=tan(3\pi /2-2\pi /12)\\=tan(\pi /4-\pi /6)\\=\frac{tan(\pi/4)-tan(\pi/6)}{1+tan(\pi/4)tan(\pi/6)}[/tex]
= [tex]\frac{1-1/\sqrt{3} }{1+1*1/\sqrt{3} } \\[/tex]
[tex]=\frac{(\sqrt{3}-1)/\sqrt{3}}{(\sqrt{3}+1))/\sqrt{3}}[/tex]
[tex]=\frac{(\sqrt{3}-1)}{(\sqrt{3}+1)}\\=\frac{(\sqrt{3}-1)(\sqrt{3}+1)}{(\sqrt{3}+1)(\sqrt{3}+1)}\\=\frac{(3-2\sqrt{3}+1)}{(3-1)}\\\\=\frac{(4-2\sqrt{3})}{(2)}\\={(2-\sqrt{3})}\\[/tex]


Thus, the required value of the trigonometric operator tan(π/12) = 2 -√3. None of them is correct.

Answer:

The factor is 4.

Step-by-step explanation:

You can divide both 24 and 20 by 4, leaving you with 6x-5.

Highest common factor should be 4.

Answer:

x  = 5t - a

Step-by-step explanation:

The problem deals with making a variable the subject of the formula in the expression.

 Given expression:

            6x + a = 5(x + t)

  We are to make x the subject of the formula in the expression

Solution:

           6x + a  = 5(x+t)

On the right hand side, expand the parentheses and distribute the term outside;

          6x + a  = 5x + 5t

   Bring the term desired to be the subject to one side by adding (-5x) to both sides;

     6x + (-5x) + a = 5x + (-5x) + 5t

           x + a  = 5t

  Now add (-a) to both sides

         x + a + (-a) = 5t + (-a)

          x  = 5t - a

So Scientific Notation is like this.

Ya got a big number that has of 0s . Let's just throw out 69,000,000,000,000

You take the other numbers that arent 0s. Take the first number and put a "." in between it and the second number. So, in this case, you have 6.9, like this.

You then count the number of 0s and +1. So in this case, you'll have 12+1. Which is 13.

You then take the 6.9 and note it with a *10. You then take the 13 and put it on the 10 as an exponent. So in the end youll have 6.9*10^13.

Answer: there's no answer, the correct answer is f(x) = -14x3 + 7x2

Step-by-step explanation:

1. f(x) = 14x3 − 7x2 + 6

2. reflection over y-axis : f(x) = -14x3 + 7x2 - 6

3. shift 6 units up : f(x) = -14x3 + 7x2 - 6 + 6

4. f(x) = -14x3 + 7x2

The correct function after reflection across the y-axis and shifts it 6 units up is,

⇒ h (x) = - 14x³ - 7x² + 12

A relation between a set of inputs having one output each is called a function.

We have to given that;

The function is,

⇒ f (x) = 14x³ - 7x² + 6

Now, After reflection across the y-axis we get;

⇒ f (x) = f (- x)

⇒ f (-x) = 14 (-x)³ - 7 (-x)² + 6

⇒ f (-x) = - 14x³ - 7x² + 6

And, After shifts it 6 units up, we get;

⇒ f (x) = f (x) + 6

Hence, We get the value of function is,

⇒ h (x) = - 14x³ - 7x² + 6 + 6

⇒ h (x) = - 14x³ - 7x² + 12

Answer:

Step-by-step explanation: f1 =7

f2 = 5(7) + 2 = 37

f3 = 5(37) + 2 = 27

f4 = 5(9) + 2 = 47____

The value of f(4)f(4) f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2 is,

121.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, f(1) = 7f(1) = 7 and f(n) = f(n-1) + 2f(n) = f(n−1) + 2.

By this pattern,

f(4)f(4) = [f(4 - 1) + 2f(4)][f(4 - 1) + 2f(4)].

f(4)f(4) =  [f(3) + 2f(4)][f(3) + 2f(4)].

f(4)f(4) =  [f(3) + 2(4)][f(3) + 2(4)].

f(4)f(4) =  [3 + 8][3 + 8].

f(4)f(4) =  [11][11].

f(4)f(4) =  121.
