To think intuitively of what it means to take a number to a negative power, first consider how we define taking a number to a positive power.

Before we even get there, though, consider how we define multiplication as repeated addition. When you see an expression like 3 x 5, what that essentially translates to is "add 3 to itself 5 times," so we could also write 3 x 5 as 3 + 3 + 3 + 3 + 3. Having established that, around middle school, you'll typically get your first exposure to positive exponents, which are defined at first as repeated multiplication. When you see something like [tex]3^5[/tex], we could also read that as "multiply 3 by itself 5 times," or [tex]3\times3\times3\times3\times3[/tex].

With that definition for positive exponents defined, it makes sense that we would define negative exponents in terms of the inverse of repeated multiplication: repeated division. Each time we step the exponent back by 1, we divide by the base again. For example, let's take these decreasing powers of 3 and notice what happens:

[tex]3^3 = 27\\3^2=27/3=9\\3^1=9/3=3\\3^0=3/3=1[/tex]

If we start stepping back further, we start getting to values below 1:

[tex]3^{-1}=1/3\\3^{-2}=(1/3)/3=1/3^2=1/9\\ 3^{-3}=(1/9)/3=1/3^3=1/27[/tex]

And this pattern continues, with the essential takeaway being that [tex]3^{-x}=1/3^x[/tex]

Try applying that pattern to the equation you've been given, [tex]y=4\cdot2^{-6}[/tex], and see what you get!

3. Find the scale factor using the given scale drawings and measurement below

Answers

Final answer:

The question asks to find the scale factor for given scale drawings and measurements. A scale factor is computed by creating a ratio comparing the measurement of the scale drawing to the actual measurement, simplifying that ratio to find the scale factor.

Explanation:

The subject of the question is concerned with finding the scale factor from a given scale drawing and measurements. In mathematics, particularly in geometry, a scale factor is used to transform the size of a figure without altering its shape.

Step-by-Step Explanation

To find the scale factor for each given scale drawing, you will need to create a ratio or a fraction that compares the scale measurement to the actual measurement. Here’s how you might solve one of the problems:

Example: What is the scale factor if 3 inches is equal to 12 feet?

Solution:

Convert all measurements to the same unit, for instance, turn feet into inches (1 foot = 12 inches).Write the ratio of the scale drawing to the actual measurement.Reduce the ratio to its simplest form to find the scale factor.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The equation of the base circle is given below.

x² + y² = 81

x² + y² = 9²

Then the radius of the circle is 9 units. Then the height of the cone is the same as the diameter of the circle.

h = 2r

h = 2 x 9 = 18

The volume of the cone will be

V = (1/3)πr²h

V = (1/3) × π × 9² × 18

V = 1526.8 cubic units

The area of the vertical cross-section A at the level x = 6 will be

A = (1/2) x (18 - 6) x (18 - 6)

A = (1/2) x 12²

A = (1/2) x 144

A = 72 square units

which of the following shows a strategy to use to find 4x275 (4x300)+(4x25)
(4x300)-(4x25) (4x275)-100 (4x200)+75

Answers

[tex]4*275 (4x^3^0^0)+(4x^2^5) (4x^3^0^0)-(4x^2^5) (4x^2^7^5)-100 (4x^2^0^0)+75[/tex] 


The correct strategy is (4x275) - 100. So option (3) is correct.

To find 4 multiplied by 275 using the given strategies, let's go through each one:

1. (4x300) + (4x25):

First, calculate (4x300) = 1200. Then, calculate (4x25) = 100. Finally, add these results together: 1200 + 100 = 1300.

2. (4x300) - (4x25):

Calculate (4x300) = 1200. Then, calculate (4x25) = 100. Now, subtract the second result from the first: 1200 - 100 = 1100.

3. (4x275) - 100:

Simply multiply 4 by 275 to get 1100. Then, subtract 100: 1100 - 100 = 1000.

4. (4x200) + 75:

Calculate (4x200) = 800. Then, add 75: 800 + 75 = 875.

The correct strategy is the third one: (4x275) - 100.

Detailed Calculation:

1. [tex]\(4 \times 275 = 1100\)[/tex]

2. [tex]\(1100 - 100 = 1000\)[/tex]

So, using the strategy of (4x275) - 100, the result is 1000.

If the circumference of a circle is 201 centimeters what is the radius of the circle (to the nearest whole number)? Use 3.14 for pi



A) 32 centimeters
B) 128 centimeters
C) none
D) 16 centimeters
E) 64 centimeters

Answers

Final answer:

The radius of a circle with a circumference of 201 centimeters is approximately 32 centimeters, found by dividing the circumference by 2 times pi (π), using 3.14 as the value of pi. The correct answer is A) 32 centimeters.

Explanation:

The question asks us to find the radius of a circle when its circumference is given to be 201 centimeters. We use the circumference formula of a circle, which is C = 2πr, where C stands for circumference, π (pi) is a constant approximately equal to 3.14, and r represents the radius of the circle.

To find the radius, we rearrange this formula to solve for r:

Divide both sides of the equation by 2π to isolate r.

Plug in the given circumference value, C = 201 cm, and the approximate value of pi, π = 3.14, into the rearranged formula.

So the calculation would be r = C / (2π) = 201 / (2 * 3.14) = 201 / 6.28. When we compute this, we get r ≈ 32 centimeters to the nearest whole number.

Therefore, the correct answer is A) 32 centimeters.

The sum of the square of two consecutive whole number is 25. Find the numbers

Answers

Don't you mean "the sum of the squares ..."?
The sum of the squares of two consecutive whole numbers is 25.  Find the numbers.  Let the first be represented by x and the second by x+1.
Then x^2+(x+1)^2=25.  Expanding, x^2+x^2+2x+1=25.
Rewriting this as a quadratic equation in standard form,

2x^2+2x+1=25, or 2x^2+2x-24=0.  Simplifying, x^2+x-12=0.
Factoring, (x-3)(x+4)=0.  Solving for x:  x-3=0, so x=3; x+4=0, so x=-4.
Choose the positive x value:  x=3.  Then the next consecutive number is 2+1=3+1=4.

Check:  Does 3^2 + 4^2 = 5^2 = 25?  Yes.
The numbers are 3 and 4.

rewrite 8/9 with a denominator of 63

Answers

To write 9 as 63, you need to multiply it by a number. 63/9 = 7.
So you need to multiply 9 by 7 to get 63.

But since it's a fraction, you can't multiply the denominator without multiply the numerator. So you need to multiply the denominator, 9, by 7 and the numerator, 8, by 7.

8/9 = (8*7) / (9*7) = 56/63

So 8/9 = 56/63

Hope this helps! :)

Final answer:

To rewrite the fraction 8/9 with a denominator of 63, multiply both the numerator and denominator by 7 to get 56/63.

Explanation:

To rewrite 8/9 with a denominator of 63, you need to find a number that you can multiply both the numerator (8) and the denominator (9) of the original fraction by, so that the denominator becomes 63. To do this, divide 63 by the original denominator, 9, which gives you 7. Thus, the number you need to multiply by is 7.

Multiply both the numerator and the denominator by 7:

Numerator: 8  times 7 = 56

Denominator: 9 times 7 = 63

Therefore, the fraction 8/9 with a denominator of 63 is 56/63.

What's the highest term that goes into 12x³, 8x², and 12x evenly? If it helps, you can break it up into two questions: what's the greatest common factor between 12 and 8, and what's the greatest common factor between x³, x², and x? Once you have those, multiply the two together, and you'll have the greatest common factor for all three monomials.

Also important to keep in mind: when we say we want to "factor" an expression with more than one term added together, what we really want to do is reverse the distributive property. In case you've forgotten, the distributive property is a property of multiplication that states that if you have three numbers a, b, and c, a(b+c) = ab + ac. You distribute the a to each of the terms in the parentheses. Here, you're given the ab + ac part, and you have to work your way back. To give an example, if we had the expression:

[tex]24x+36[/tex]

We can use the fact that 12 is the greatest common factor of 24x and 36 to rewrite it:

[tex]12(2x)+12(3)[/tex]

And, realizing that 12 has been distributed to the 2x and the 3, reverse the distributive property to get:

[tex]12(2x)+12(3)=12(2x+3)[/tex]

Final answer:

To evaluate the expression 4x-3 for x = -3, we substitute -3 into the expression and follow the order of operations, resulting in a value of -15.

Explanation:

To evaluate the expression 4x-3 when x is -3, we simply substitute -3 in place of x and calculate the result as follows:

Replace x with -3: 4(-3) - 3.Multiply 4 by -3: -12 - 3.Finally, subtract 3 from -12 to get: -15.

Therefore, evaluating 4x-3 when x is -3 gives us -15.

The value V of a square glass varies directly as the square of its length X cm. If the value of a square glass with length 3 cm is $243, find the value of a glass with length 5 cm

Answers

Given that the value V of a square glass varies directly as the square of its length X cm.

Then, the variation equation is given by

[tex]V\propto X^2 \\ \\ \Rightarrow V=kX^2[/tex]

Given that value of a square glass with length 3 cm is $243, we have:

[tex]243=k(3)^2=9k \\ \\ \Rightarrow k= \frac{243}{9} =27 \\ \\ \Rightarrow V=27X^2[/tex]

Thus, the value of a glass with length 5 cm is

[tex]V=27(5)^2=27\times25=\bold{\$675} [/tex]

The value V of a square glass varies directly as the square of its length X cm. This means that V is proportional to [tex]X^2[/tex], which can be expressed as:

[tex]\[ V = kX^2 \][/tex]

where k is the constant of proportionality.

Given that the value of a square glass with length 3 cm is $243, we can use this information to find the constant k:

[tex]\[ 243 = k(3)^2 \][/tex]

[tex]\[ 243 = 9k \][/tex]

[tex]\[ k = \frac{243}{9} \][/tex]

[tex]\[ k = 27 \][/tex]

Now that we have the value of k, we can find the value of a glass with length 5 cm by substituting X = 5 into the original equation:

[tex]\[ V = 27(5)^2 \][/tex]

[tex]\[ V = 27 \times 25 \][/tex]

[tex]\[ V = 675 \][/tex]

Therefore, the value of a glass with length 5 cm is $675.

The answer is: 675.
