If you're adding positive numbers together, then the order in which you write or group the addends doesn't matter.

If you're "adding" a negative number to a positive number, it's a little easier to visualize this problem if you write the positive number first, followed by the negative number.

But if you're "adding" -15 to 8, it'd make sense to write the -15 first (because its magnitude is greater) and then the 8: -15 + 8 = -7

Which statements are true of the function f(x) = 3(2.5)x? Check all that apply. a) the function is exponentioal b)The initial va

AnnyKZ [126]

Answer:

a) The function is exponential

c) The function increases by a factor of 2.5 for each unit increase in x.

d) The domain of the function is all real numbers.

Step-by-step explanation:

Exponential functions are written y = a(b)ˣ.

a) the function is exponential is true.

"a" represents the initial value, or the y-intercept.

"b" represents the rate of increase or decrease.

"x" and "y" represent points on the function.

Since a = 3, the initial value is 3.

b) The initial value of the function is 2.5 is false.

Since b = 2.5, the rate of change is 2.5

c)The function increases by a factor of 2.5 for each unit increase in x is true.

When you graph the function, (see graph below), you can see the information clearly.

The domain means how far the graph will go left to right. The graph will continue left to negative infinity, and will continue to the right to positive infinity. This make the domain all real numbers.

d)The domain of the function is all real numbers is true.

The range is how far up or down the graph will reach. Exponential functions have a horizontal asymptote, which is where the graph gets very close to touching a horizontal line, but never will. The asymptote is on the left of the y-axis. The range is all real numbers greater than 0.

e)The range of the function is all real numbers greater than 3 is false.

"3" is the initial value, but the graph extends behind the y-axis too.

Adrian Beltre hit 48 home runs during the 2004 Major League Baseball season, but only hit 19 home runs in the 2005 season. By wh

aliya0001 [1]

Answer:

60.42%

Step-by-step explanation:

Number of home runs hit by Adrian Beltre in 2004 = 48

Number of home runs hit by Adrian Beltre in 2005 = 19

To find:

Percentage decrease in home run production from 2004 to 2005.

Solution:

To find the percentage decrease, first of all we need to find the decrease in the number of home runs and then we will divide with the number of home runs in 2004 and then finally will multiply the result with 100 to get the percentage decrease.

Decrease in the number of home runs = Number of home runs in 2004 - Number of home runs in 2005 = 48 - 19 = 29

$\text{Percentage of decrease in Home runs} = \dfrac{\text{Decrease in home runs}}{\text{Number of home runs in 2004}}\times 100\\\Rightarrow \text{Percentage of decrease in Home runs} = \dfrac{29}{48}\times 100 \approx \bold{60.42\%}$

Therefore, by 60.42% Beltre's home run production has decreased from 2004 to 2005.

Suppose that the universal set is U={1,2,3,4,5,6,7,8,9,10}. Express each of the following subsets with bit strings (of length 10

Vladimir [108]

Answer:

0011100000

1010010001

0111001110

Step-by-step explanation:

As the question is not complete, Here is the complete question.

Suppose that the universal set is U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Express each of these sets with bit strings where the ith bit in the string is 1 if i is in the set and 0 otherwise.

a) {3, 4, 5}

b) {1, 3, 6, 10}

c) {2, 3, 4, 7, 8, 9}.

So, we need to express a) b) and c) into bit strings.

Firstly, number of elements in the universal set represent the number of bits in the bit string.

Secondly, 1 = yes element is present in both universal set as well as in sub set.

0 = No, element is not present in sub set but present in universal set.

Hence, we have:

a) Sub set {3,4,5} = 0011100000 (As there are 3 1's which means only 3,4,5 are present in both universal set and subset.

Similarly,

b) Sub set {1, 3, 6, 10} = 1010010001

c) Sub set {2, 3, 4, 7, 8, 9} = 0111001110
