3. Write an equation using function notation to represent this situation.

Answer:

18 Kg

Step-by-step explanation:

We can use algebra to solve for the mass, m, given the delivery price, $70.

Starting with the formula:

price ($) = 7 + 3.5m

We can substitute $70 for price ($) and solve for m:

$70 = 7 + 3.5m

Subtracting 7 from both sides:

$63 = 3.5m

Dividing both sides by 3.5:

m = 18

Therefore, the mass of the parcel is 18 kg.

Answer:

A. 12 TT

B. 6 TT

C. 9 TT

D. 18 TT

The correct answer is D. 18 TT. The formula for circumference is C = 2TT x radius, so with TT equal to 3.14, the circumference of the circle is 18.28 TT which is approximately equal to 18 TT.

Step-by-step explanation:

You want the numbers for quotient, dividend, and remainder in the area model of 49÷3.

The number in each rectangle is its area, which is the product of the divisor on the left and the quotient at the top. These can be considered the length and width of the rectangle. The rectangle area is their product.

The remainder is put in the box at upper right. It is a value that is smaller than the divisor on the left.

The line at the bottom summarizes the division. The quotient is the sum of the quotient values at the top of the model, and the remainder is what's left over: the number that is too small to divide further.

The probability that we get the same faces when we roll 3 fair six-faced dice is 44.44%.

Simply put, the probability is the likelihood that something will occur.

We can discuss the likelihood of several outcomes or the potential of one outcome when we are unsure of how something will turn out.

Statistics is the study of events that fall into a probability distribution.

Therefore, there is a chance that each one is unique:

6/6 * 5/6 * 4/6 = 120/216

Therefore, the likelihood that at least two of them will display the same face is:

1 - 120/216 = 96 / 216 =44.44%

Therefore, the probability that we get the same faces when we roll 3 fair six-faced dice is 44.44%.

The formula to solve this is given as

K = log (A / Ao)

Where we have k to be the constant that is measured on the richter scale as 4.2

Then when we put this in the formula, we would have:

4.2 = log (A / Ao)

take the log of both sides of the equation

the ordered pair will be (3,-1) lies in the inverse function.

What is inverse function?

A function that returns the initial value for which a function has produced output is called an inverse function. If f(x) is a function that produces the value y, then f-1(y), which is the inverse function of y, will produce the value x. Inverse and reciprocal functions should not be confused. The output's original value is returned by the function's inverse, which is represented by the symbol f-1 (x). While the reciprocal of a function is represented by 1/f(x) or f(x)-1

Those that do are referred to as invertible. For a function f: X Y to have an inverse, it must possess the characteristic that there is exactly one x in X such that f(x) = y for every y in Y. This characteristic guarantees the existence of a function g: Y X that has the required connection to f.

function g(x)=∛(x−4)

So the inverse of the function

g ¬(x) = x³+4

The simplified expression of 1+sin^2-cos^x / 2sin^2x  issin^2(x) / 2(1 + cos(x)) + 1 / 2(1 - cos(x))

To simplify this expression, we can first simplify the numerator by combining the terms inside the parentheses:

1 + sin^2(x) - cos(x) = sin^2(x) + 1 - cos(x)

Next, we can factor the denominator trigonometric identity sin^2(x) + cos^2(x) = 1:

2 sin^2(x) = 2(1 - cos^2(x)) = 2 - 2cos^2(x)

Now we can substitute these simplified expressions into the original expression:

(1 + sin^2(x) - cos(x)) / (2 sin^2(x))

= (sin^2(x) + 1 - cos(x)) / (2 - 2cos^2(x))

= [(1 - cos(x)) + sin^2(x)] / [2(1 - cos(x))(1 + cos(x))]

Answer:

  (d)  6.3

Step-by-step explanation:

You want the measure of side CD in ∆CDE ~ ∆CFG with CG=6, GE=2.4, and FD=1.8.

The corresponding sides of the two triangles are proportional:

  CD/CE = FD/GE

  CD = CE×FD/GE = (6+2.4)×1.8/2.4

  CD = 6.3

__

Additional comment

Lengths on segment CD are 3/4 of those on segment CE, so CF = 4.5. CD is the sum of CF and FD: 4.5 +1.8 = 6.3.

Answer: 8.9 and 6.7

Step-by-step explanation:

These are right triangles, so you can use the Pythagorean theorem, a² + b² = c², where a and b are the legs, or shorter sides, of the triangle and c is the hypotenuse, or the longest side.

1. 4² + 8² = c²

16 + 64 = c²

80 = c²

c = √80

c = 8.9

2. 6² + 3² = c²

36 + 9 = c²

45 = c²

c = √45

6 km = 6000 m

5 min = 300 s

6000m / 300s  = 20 m/s

Answer:

20 m/s

Step-by-step explanation:

The average speed of the fish can be calculated by dividing the distance traveled by the time taken.

First, we need to convert the distance from km to meters:

6 km = 6,000 meters

Next, we need to convert the time from minutes to seconds:

5 minutes = 5 × 60 = 300 seconds

Finally, we divide the distance traveled by the time taken:

Average speed = 6000 meters / 300 seconds = 20 m/s

So, the average speed of the fish is 20 m/s.

Using the formula of Interest I = PRT and given values the value of P is $5250.

Interest is the sum over and above the original amount (the amount borrowed) that is paid to a lender or depositor by a borrower or deposit-taking financial institution at a set rate. Interest differs from profit, in that interest is received by a lender, whereas profit is received by the owner of an asset, investment or enterprise.

Given that, the formula is I = PRT

I = $7140, R = 0.17, T = 8

To find the value of P, from the formula

7140 = P * 0.17 * 8

⇒ 7140 = P * 1.36

divide both sides with 1.36 we get

⇒ 7140/1.36 = P

⇒ P = $5,250

The radius of the top of a cylinder is always the same length as the radius of the base of a cylinder.

Radius of the base of can A: 10 cm

Radius of the base of can B: 18 cm

Area of the base of can A:

[tex]A=\pi (10^{2} )[/tex]

[tex]A=100\pi[/tex]

[tex]A=314[/tex] cm (Assuming we're only using 3.14 and not any other decimals)

[tex]A=324\pi[/tex]

[tex]A=1017.36[/tex] cm (Again, assuming we're only using 3.14 and not any other decimals)

The interquartile range is least affected by an outlying value in the data set of the range, interquartile range, and variance is True.

Max to min value is the range. Range can substantially change if there are any outliers.

Since the threshold values for Q3 and Q1 are not outliers, the IQR won't change.

Outliers cause variance to be misinterpreted since they vastly increase variance.

Interquartile range:

You may determine the spread of the midpoint of your distribution using the interquartile range.

The interquartile range contains half of the values for any distribution that is ordered from low to high. The first 25% of values are found in the first quartile (Q1), while the last 25% are found in the fourth quartile (Q4).

The third quartile (Q3) less the first quartile (Q1) is the interquartile range (Q1). This provides us with the data set's middle half's range.

The interquartile range is calculated using only 2 values, much like the range. The IQR, however, is less impacted by outliers because the two values are more likely to be average scores because they are drawn from the middle of the data set.

The IQR provides a reliable indicator of variability for both skewed and normal distributions.
