Team Tackle's score was 28 points. And team Sack's score was 9 points.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

During the 2005 football season, Team Tackle beat Team Sack by 19 points. If their combined scores totaled 37.

Let 'x' be the Tackle's score and 'y' be the Sack's score. Then the equations are given as,

x + y = 37        ...1

x = y + 19        ...2

From equations 1 and 2, then we have

y + 19 + y = 37

2y = 18

y = 9

Then the value of 'x' is given as,

x = 9 + 19

x = 28

Team Tackle's score was 28 points. And team Sack's score was 9 points.

From the given information we can see:

Use the equation for the sum of the first n terms:

Answer:

[tex]S_7=6554[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7 cm}\underline{Sum of the first $n$ terms of a geometric series}\\\\$S_n=\dfrac{a(1-r^n)}{1-r}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}[/tex]

Given geometric series:

[tex]2-8+32-...+a_n[/tex]

The first term (a) of the sequence is 2:

[tex]\implies a=2[/tex]

To find the common ratio (r), divide consecutive terms:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{-8}{2}=-4[/tex]

To find the sum of the first 7 terms, substitute the found values of a and r into the formula, along with n = 7:

[tex]\implies S_7=\dfrac{2(1-(-4)^7)}{1-(-4)}[/tex]

[tex]\implies S_7=\dfrac{2(1-(-16384))}{5}[/tex]

[tex]\implies S_7=\dfrac{2(16385)}{5}[/tex]

The second function 100(.1593)^t decays faster than the first function 100(.2661)^t.

To find which function decays the fastest, we need to compare the decay rates of the two functions.

The decay rate of a function is determined by the exponent in the function. In this case, the exponent is t.

The smaller the exponent, the faster the decay rate.

So, in the first function 100(.2661)^t, the exponent is t.

In the second function 100(.1593)^t, the exponent is also t.

We can compare the decay rates of the two functions by comparing the values of the bases, .2661 and .1593.

The base of a function represents the rate of decay, the smaller the base the faster the decay rate.

As x gets very large , the function that becomes largest is y = 5x^3

An exponential function is a Mathematical function in the form f (x) = a^x, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

An exponential function is defined by the formula f(x) = a^x, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x. Where a>0 and a is not equal to 1. x is any real number.

This means that the greater the power of x , the larger the function of y.

For example, If y = 5x^n , as n increases the value of x increases and the value of y will increase also.

Therefore the largest function as x becomes large is y = 5x^3

1234 in. set A and 1234 in set B and 1234 in set C so the answer is (1234)

The value of the set ( A ∩ C )' = A' ∪ C' = { 4 , 5 , 6 , 7 , 8 }

The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.

Given data ,

Let the universal set be represented as U

The value of U = { 1, 2, 3, 4, 5, 6, 7, 8 }

Let the value of set A = { 1 , 2 , 3 , 4 }

Let the value of set C = { 1 , 2 , 3 , 6 , 8 }

Now , the equation of set is  ( A ∩ C )'

The value of ( A ∩ C )' = A' ∪ C'

Substituting the values in the equation , we get

A' = U - A

A' = { 1, 2, 3, 4, 5, 6, 7, 8 } - { 1 , 2 , 3 , 4 }

A' = { 5 , 6 , 7 , 8 }

And ,

C' = U - C

C' = { 1, 2, 3, 4, 5, 6, 7, 8 } - { 1 , 2 , 3 , 6 , 8 }

C' = { 4 , 5 , 7 }

So , ( A ∩ C )' = A' ∪ C'

Substituting the values in the equation , we get

( A ∩ C )' = { 4 , 5 , 6 , 7 , 8 }

Hence , the set ( A ∩ C )' is { 4 , 5 , 6 , 7 , 8 }

Answer:

62.5%

Step-by-step explanation:

(mass of solute/mass of solution) x 100 = 62.5%

The equation, 6(-2 + 4) = -12 + 24, illustrates E. the Distributive Property of Multiplication over Addition.

In this mathematical property, the multiplication of two or more addends by a number results in the same value as multiplying each addend individually by the number and then adding the products together.

For instance, 6(-2 + 4) = -12 + 24

= 12

OR:

6(-2 + 4) = 6 x 2

= 12

In this situation, we can either multiply the numbers in parenthesis individually by 6 or sum the parenthesis and then multiply the sum by 6.  Either way yields the same result, showing that multiplication is distributive.

Thus, in the equation, the property illustrated is Option E, not the commutative properties of addition and multiplication, the inverse properties of addition and multiplication, the associative properties of addition and multiplication, or the identity properties of addition and addition multiplication.

Answer:

Step-by-step explanation:

Assuming that the area is a rectangle with no obstructions or furniture, and that the people are standing shoulder-to-shoulder, then the area can fit approximately 200,000 people. This is calculated by multiplying 250 feet by 250 feet to get the total square feet of the area, which is 62,500 (250 x 250 = 62,500). Then divide the total square feet by the amount of space taken up by one person, which is 2.5 square feet, to get the approximate number of people that can fit in the area. 62,500 / 2.5 = 25,000, so 25,000 x 8 = 200,000 people.

Answer:

An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.

The rectangular form of of a complex number is given by z = a + ib where

where

Given the complex number

z = 2[cos(- π/4) + isin(- π/4)] , we desire to find the rectangular form of the complex number. We proceed as follows.

z = 2[cos(- π/4) + isin(- π/4)]

z = 2cos(- π/4) + i2sin(- π/4)]

z = 2cos(π/4) - i2sin(-π/4)]

Since cos(π/4) = sin(π/4) = 1/√2, we have that

z = 2cos(π/4) - i2sin(-π/4)]

z = 2 × 1/√2 - i2 × 1/√2

z = 2/√2 - i2/√2

Rationalizing the denominators, we have that

z = 2/√2 × √2/√2 - i2/√2 × √2/√2

z = 2√2/2 - i2√2/√2

z = √2 - i√2

So, we have the number in rectangular form as z = √2 - i√2

Step-by-step explanation:

The area of the 10 feet by 10 feet square is 100 square feet. If 20 people fit comfortably in this area, we can use this information to estimate the number of people in a larger area.

Since we know that 20 people fit in 100 square feet, we can calculate how many people would fit in a larger area by multiplying the number of square feet by 20.

A 1 mile section of a parade route is approximately 5280 feet long and 12 feet deep (on one side of the street). Therefore, the area that the crowd is occupying is approximately 5280*12 = 63,360 square feet.

So, the number of people that would fit in this area would be approximately:

63,360 square feet * 20 people/100 square feet = 1267.2 people.
