What is the domain of this exponential function?

Answer:

1+2+27=30

3+6+21=30

20+3+7=30

So many more, but here are a few.

To find three numbers that add up to 30, you can choose different combinations. For example, you could use 10, 10, and 10 or figures like 15, 10, and 5. The specific numbers can vary based on the criteria involved.

When dealing with numbers that add up to a specific value, there are many possible combinations depending on the criteria you use. For example, if you wish to find three different positive numbers that add up to 30, you could choose 10, 10, and 10. This is because each number is significant and can be repeated in this scenario. These would add up to 30, as 10+10+10 equals 30.

Alternatively, you could choose a variety of numbers such as 15, 10, and 5, which also add to 30. Here the expression is set up as 15 + 10 + 5. Another option could be three unit conversion factors like 12, 8, and 10. The method of finding three numbers that add up to a certain sum is an extension of practical problem-solving often used in daily life.

Answer:

8 inches

Step-by-step explanation:

if the house is actually 96 feet then you would have to divide 96 by 12 since the question states that one inch equal 12 feet and by dividing you would come up with the length by inches for the blueprint.

96/12=8

Option A, F(x) = x, is the correct linear parent function because it represents a straight line with a slope of 1 that passes through the origin.

The linear parent function is the simplest form of a linear equation, which is described by a straight line with a slope of 1 and goes through the origin (0,0) on a coordinate plane. Among the options given, the correct answer is A. F(x) = x. This function represents a straight line that has a slope (gradient) of 1 and passes through the origin, making it the parent function for all linear equations. Options B, C, and D are not linear parent functions; B represents a linear function with a y-intercept of 1, C is a reciprocal function, and D is a quadratic function.

That's what my calculator said

Answer:

32.59

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term and r the common ratio )

4[tex](\frac{8}{9}) ^{n-1}[/tex] ← is the n th term expression

with a = 4 and r = [tex]\frac{8}{9}[/tex]

The sum of n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(1-r^n)}{1-r}[/tex], thus

[tex]S_{20}[/tex] = [tex]\frac{4((1-\frac{8}{9}) ^{20}) }{1-\frac{8}{9} }[/tex]

      = [tex]\frac{4(1-\frac{8^{20} }{9^{20} } )}{\frac{1}{9} }[/tex]

      = 36( 1 - 0.0948)

      = 36(0.905)

      = 32.59 ( to the nearest hundredth )

676000

Step-by-step explanation

3 digits of the 5-digit code are number 0-9 which is 10 numbers that could go into that spot, after the three digits there are two letters and because there are 26 letters in the alphabet you would multiply 10*10*10*26*26 which equals 676000

There are 676,000 possible codes.

An arrangement of objects where the order in which the objects are selected does not matter.

Given that  library labels each book with a five-digit code to identify the books in their computer system.

Each code is 3 digits (0-9) followed by two letters

We need to find the possible number of codes.

There are 10 possible digits (0-9) for each of the first three positions, and 26 possible letters (A-Z) for each of the last two positions. Therefore, the total number of possible codes is:

10 x 10 x 10 x 26 x 26 = 676,000

Hence, there are 676,000 possible codes.

To identify the shaded part of a 100 grid as a fraction, count the shaded squares; each represents 1%, making the denominator 100. The fraction formed can be simplified if possible, and converting it to a decimal involves dividing the numerator by the denominator.

To identify the shaded part of a 100 grid as a fraction and a decimal, you must first count the number of shaded squares. Since each square represents 1% of the total grid, the number of shaded squares can be directly written as a percent. For example, if 45 squares are shaded, the shaded part would represent 45%.

As a fraction, this is equal to 45/100, because the denominator should be 100 in order to represent a percent as a fraction.

To convert this fraction to a decimal, divide the numerator by the denominator which gives 0.45. If you have shaded half the grid, it means 50 squares are shaded out of 100. The fraction would therefore be 50/100, which simplifies to 1/2, and the decimal would be 0.50.

Nth term works by having n as the term's place in the sequence.

So the first term , n=1 and you work it out from there

Second term, n=2 and you work it out from there

And so on

So:

4×1 = 4 - 2 = 2

4×2 = 8 - 2 = 6

4×3 = 12 - 2 = 10

4×4 = 16 - 2 = 14

Answer:

yes you are correct 50 is 5 times as many as 10 because 10 times 5 is 50 thank me later

Step-by-step explanation:

The statement is indeed correct: 50 is 5 times as many as 10. This understanding comes from the powers-of-ten notation system. We can also relate this to the concept of order of magnitude; the order of magnitude of 50 is 10², providing an approximation of its size in powers of ten.

The question is asking if the number 50 is 5 times as many as 10. In mathematics, if you multiply 10 by 5, you do get 50, so the statement is indeed correct. This concept is part of multiplication and understood by using the powers-of-ten notation system, which is based on increases of ten.

The powers-of-ten notation system is the basis of our counting system, where each digit's place is ten times greater than the digit to its right. This notation system is used because humans have ten fingers and started counting with them.

An interesting approach is to relate this to order of magnitude. The order of magnitude of 50 is 10² because it's closer to 10² (100) than 10³ (1000). The order of magnitude only changes when you pass the square root of 10 (~3.16). Since 5 is greater than 3.16, when you multiply it by 10, it surpasses 10² (100), giving the order of magnitude as 10³. This is slightly off from the actual value of 50, illustrating how order of magnitude provides an approximation, not an exact value.

Answer: -118

Step-by-step explanation:

first multiply by 40. 37x 40 is 1480. No subtract 64 from both sides (1416). Multiply both sides by negative one to make the parentheses positive. -(1416)

on the inside that would be 12y so divide -1416 by 12 which is -118

Answer: 6.25.

Step-by-step explanation:

Let's put your question into a proper proportional form, because it is a ratio that is equal.

[tex]\frac{5}{12} = \frac{x}{15}[/tex]

To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.

[tex]5 * 15 / 12 = 6.25[/tex]

The answer you should get by doing this is 6.25.

Answer:

x=6.25

Step-by-step explanation:

Cross multiply

5/12=x/15

12*x=15*5

12x=75

Divide both sides by 12 to isolate the variable x

x=6.25

Or, multiply both sides by 15 to "reverse" the division being done to x

5/12=x/15

15*5/12=x/15*15

6.25=x

Step-by-step explanation: when you take 521 and divide it by 4 you get 130.25, which is about 130, making you choose answer choice B. (lol i like your profile picture too!!)

A half-life is how long it takes for half of the amount to go away. in this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.

36mins/16mins = 2 half lives.
