In 8 years Jack will be three times as old as he is now. How old is he now?

Answer:

27

Step-by-step explanation:

4.5*3*2 = 27

hi,

You just have to multiply the three measures.  

So :  

2*3*4.5 =  27 cm³

Easy, is it not ?  

a) If the [tex]n[/tex]-th term is [tex]x_n = cn+d[/tex], then

[tex]x_1 = c + d = 16[/tex]

[tex]x_2 = 2c + d = 19[/tex]

Eliminating [tex]d[/tex],

[tex](2c+d) - (c+d) = 19-16 \implies c = 3[/tex]

Solving for [tex]d[/tex],

[tex]3 + d = 16 \implies d = 13[/tex]

Then

[tex]\boxed{x_n = 3n + 13}[/tex]

b) When [tex]n=11[/tex], we get

[tex]x_{11} = 3\cdot11 + 13 = \boxed{46}[/tex]

The difference quotient of the function that has been presented to us will turn out to be 5.

In this step, we wish to determine the difference quotient for the function that was supplied.

To begin, keep in mind that the difference quotient may be calculated by:

Lim h->0 [tex]\frac{f(x+h)-f(x)}{h}[/tex]

Now, for the purpose of the function, we need this:

Then we will have:

[tex]$$\begin{aligned}&\lim _{h \rightarrow 0} \frac{j(x+h)-j(x)}{h} \\&\lim _{h \rightarrow 0} \frac{5 *(x+h)-3-5 * x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 x+5 h-3-5 x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 h}{h}=5\end{aligned}$$[/tex]

j(x) = 5x - 3

Then the following will be true:

Therefore, 5 is the value of the difference quotient for j(x) is %

Considering that the transformation is a dilation, the correct statement is given by:

The angles of Quadrilateral ABCD and A'B'C'D' are the same.

There are three statements:

A figure is said to go through a dilation is when it's side lengths are changed, either enlarged or diminished, but the angles remain constant.

For this problem, the scale factor is of 2, meaning that the side lengths are doubled, while the angles remain constant and the correct statement is:

The expression for the area within the circle but outside the triangle as a function of the length 3x of the side of the triangle is [tex]\frac{88r^2}{7}-\frac{9\sqrt{3} }{2}x^2[/tex].

It is given that:-

Radius of circle = 2r

Length of side of equilateral triangle = 3x

We have to find the expression for the area within the circle but outside the triangle as a function of the length 3x of the side of the triangle.

We know that,

Area of circle = [tex]\pi R^2[/tex]

Where R is the radius of the circle.

We have R = 2r

Area of an equilateral triangle = [tex]\frac{\sqrt{3} }{2}a^2[/tex]

Where, a is the length of side of equilateral triangle.

a = 3x

Hence,

Expression = [tex]\pi R^2-\frac{\sqrt{3} }{2}a^2[/tex]

Expression = [tex]\frac{22}{7}*(2r)^2-\frac{\sqrt{3} }{2}*(3x)^2 = \frac{88r^2}{7}-\frac{9\sqrt{3} }{2}x^2[/tex].

If we select -9 in the number line, then we need to add 6. Because 6 is positive, we need to move 6 units to the right of -9, it will give:

-9 + 6 = -3

When we have two values A and B and we want to add them using the number line, the first thing we need to do is select one of these two, and locate it on the number line.

Once we did that, the other number will tell us how many units we need to move to the left (if B is negative) or to the right (if B is positive).

In this case the two numbers are -9 and 6.

If we select -9 in the number line, then we need to add 6. Because 6 is positive, we need to move 6 units to the right of -9, it will give:

There are 3 computer games she can brought at $75.

Unitary method

Unitary method is defined as the process of finding the value of a unit and then the value of a required number of units.

Given,

Arianna buys computer games from an online store.

Each game she orders costs $22 and shipping for her total is $9.

Arianna can spend no more than $75.

Here we need to find how many computer games did Arianna Brought.

Let x be the number of computer games she brought.

We know that,

Cost for one game = $22

Shipping cost = $9.

She spent = $75.

So, it can be written as,

=> 22x + 9 = 75

=> 22x = 75 - 9

=> 22x = 66

=> x = 66/22

=> x = 3.
