On a graph, the absolute value of a number is always non-negative.

The absolute value of a number is defined as the distance of that number from zero on the number line. Since the distance can never be negative, the absolute value of a number is always non-negative.

This is reflected in the graph of an absolute value function. The graph of an absolute value function, |x| is a V-shape that opens upward, with the vertex of the V being the point where the absolute value function equals zero. The two arms of the V extend out from this point, going in opposite directions along the number line. The coordinates of the vertex (0,0) and the graph is always non-negative.

It's important to note that although the absolute value is always non-negative on a graph, the input value (x) can be both positive and negative. The output of the absolute value function (|x|) will always be positive.

Daryl's weekly allowance, given the amount he ended with and the amount spent on clothes, is  $ 30

To find the weekly allowance, first find the amount that Daryl had after he had spend half his allowance on clothes. This amount can be found by the formula:

= Amount Daryl ended with - Amount gotten from cleaning oven

= 25 - 10

= $ 15

The amount of $ 15 is the amount out of Daryl's weekly allowance that he had after he had spent on clothes. The $15 is therefore half of the weekly allowance which means that the weekly allowance is:

Answer:

x = 2, -6

Step-by-step explanation:

3x + 6 = ±12
=> If 3x + 6 = 12
3x = 6
x = 2
=> If 3x + 6 = -12
3x = - 18
x = -6

Answer: 2

Step-by-step explanation: To find the value of x, we need to use the order of inverse operations. Inverse operation(s) means to do the opposite of the operations used. So, instead of adding, we subtract, instead of multiplying, we'll divide. So, the opposite of 6 + 12 is 12 - 6. So, that's 6. Now, instead of multiplying 6 by 3, we need to divide 6 by 3. That's 2. Therefore x = 2. Now, to check our answer, we plug 2 in for 6. So, | 3(2) + 6 | is the positive value of 3(2) + 6, which is 6 + 6.

12 = 12

So, therefore the absolute value of |3x+6|=12 is 2. I hope this helped!

A set comprises elements or members that can be mathematical objects of any sort, including numbers, symbols, points in space, lines, other geometric forms, variables, or even other sets. A set is the mathematical model for a collection of various things.

In set theory, the set containing every element in a collection is the union of all its sets. It is one of the fundamental operations that allows sets to be joined together and connected to one another. A union of zero sets is referred to as a nullary union, because it is by definition equivalent to the empty set.

The symbol "∩" can be used to represent the intersection of sets. According to the definition given above, the intersection of two sets A and B is the collection of all the items that are shared by both sets.

Answer:

1200

Step-by-step explanation:

step 1: Locate and underline the hundreds place (2) then look at the digit to the right (1): 1212

Step 2: The digit to the right (1) is 4 or below. So, we replace it with a 0 (zero) to get 1200 as the answer.

In short: 1212 rounded to the nearest hundred is 1200.

The percent error of Alex's measurement is 5.714%.

Percent error is a measure of how accurate a measurement is compared to the true value. It is calculated by taking the absolute value of the difference between the measured value and the true value, divided by the true value, and then multiplying by 100%.

In this case, the measured value is 3.7 cm and the true value is 3.5 cm.

To calculate the percent error, we can use the following formula:

Percent error = |(measured value - true value) / true value| x 100%

Plugging in the given values, we get:

Percent error = |(3.7 - 3.5) / 3.5| x 100%

= |0.2 / 3.5| x 100%

= 0.05714 x 100%

= 5.714%

This means that Alex's measurement is off by 5.714% from the true value, indicating that the measurement has a low accuracy.

A chord is a combination of three or more tones (notes) played together.

To determine the notes in a chord, we need to calculate the intervals between the notes. An interval is the distance between two notes. Intervals are measured in half steps (or semitones). A half step corresponds to the interval between two adjacent keys of a piano.

In a major chord, the formula for determining the intervals is 1-3-5. This means the root note (1st note) is a major third (4 half steps) away from the 3rd note and a perfect fifth (7 half steps) away from the 5th note.

For example, if the root note is C, the 3rd note is E and the 5th note is G. The intervals in this chord are C to E (4 half steps) and C to G (7 half steps). Therefore, the chord is a C major chord.

In a minor chord, the formula for determining the intervals is 1-b3-5. This means the root note is a minor third (3 half steps) away from the 3rd note and a perfect fifth (7 half steps) away from the 5th note.

For example, if the root note is F, the 3rd note is Ab and the 5th note is C. The intervals in this chord are F to Ab (3 half steps) and F to C (7 half steps). Therefore, the chord is a F minor chord.

What is the annuity problem?

An annuity is a series of equal payments made at regular intervals.

APR (Annual Percentage Rate) = 6%

Monthly payments = $800

Number of months = 18

We can use the formula for the future value of an annuity (FV) to find the savings plan balance after 18 months. The formula for the future value of an ordinary annuity is:

FV = PMT x (((1 + r)^n - 1) / r)

Where:

FV = future value of the annuity

PMT = the regular payment made

r = the interest rate per period (in this case, the monthly interest rate)

n = the number of payments or periods

The interest rate is given as an annual percentage rate (APR), so we need to divide it by the number of periods per year to find the interest rate per period. In this case, 6% / 12 months/year = 0.5% per month.

FV = 800 x (((1 + 0.005)^18 - 1) / 0.005)

FV = $15,028.63

Hence, the savings plan balance after 18 months will be 15,028.63 dollars.

Answer: The overall average of the weights is 24 pounds.

Step-by-step explanation:

To find the overall average of the weights, we need to calculate the weighted mean. A weighted mean is a type of average that takes into account the number of items or observations in each group.

In this case, we know that the average of the first 3 weights is 20 pounds and the average of the next 12 weights is 25 pounds.

To find the overall average, we will use the following formula:

( (number of items in first group * average of first group) + (number of items in second group * average of second group) ) / (number of items in first group + number of items in second group)

The formula can be applied as:

( (3 * 20) + (12 * 25) ) / (3 + 12) = (60 + 300) / 15 = 360 / 15 = 24

The translation applied to the point Q is:

T(-3, -2)

A general translation T(a, b) (that can be applied to a point (x, y)) is defined as:

T(a, b)[ (x, y)] = (x + a, y + b)

So, in this case we know that we apply a translation T(a, b) to our point Q (6, 4), and the image that we get is Q' (3, 2)

So we can write the equation:

T(a, b)[ (6, 4)] = (6 + a,  4 + b) = (3, 2)

Now we can solve that to get the values of a and b.

6 + a = 3

a = 3 - 6 = -3

Break the 3D figure into two pieces:

The relevant formulas we need are:

where r and h are the radius and height respectively.

The cylinder has radius r = 5 and height h = 17.8

V = pi*r^2*h

V = pi*5^2*17.8

V = 445pi

The cone has the same radius, but the height is h = 24-17.8 = 6.2

V = (1/3)*pi*r^2*h

V = (1/3)*pi*5^2*6.2

V = (155/3)pi

The total volume is then,

445pi+(155/3)pi

(1335/3)pi + (155/3)pi

(1335/3 + 155/3)pi

(1490/3)pi

That's the exact volume of this pencil-shaped figure. This exact volume is in terms of pi.

----------

Now to compute the approximate volume.

If you were to use pi = 3.14, then the approximate volume is

The angular speed of the wheel, in radians per second is equal to 52.37 rad/sec.

In Mathematics, an angular speed can be defined as the rate of change of angular displacement of a physical object with respect to time. This ultimately implies that, angular speed is a measure of how fast and quickly a physical object revolves or rotates relative to another point or how its angular position changes with respect to time.

Mathematically, the angular speed of a physical object can be calculated by using this formula:

ω = 2πF or ω = Δθ/Δt

Where:

Substituting the given parameters into the angular speed formula, we have;

Angular speed of the wheel, ω = 2 × 3.142 × 500

Angular speed of the wheel, ω = 3142 rad/min

In rad/sec, we would divide by 60;
