BOOMER GENERATION: At 84%, Boomers are the highest amongst all the generations that want to shop in-store. In a sample size of 75 people in the Boomer Generation, estimate how many of them prefer to shop in-store.

During the time period of 20 years the percent decreases in the country's population is 3.28%.

Percentage is a number or ratio which is a fraction of hundred.

Given,

Population of the country in 1990 = 152 million

Population of the country in 2010 = 147 million

Percent decrease in the population will be ,

= [ (1990's population - 2010's population)/1990's population ]*100

= [ (152 - 147 )/152]*100

= [5/152]*100

= 3.28%

Hence , the decrease in the population will be 3.28%.

a) The function velocity of the particle is v(t) = 0.5 · t² + 6 · t + 7, b) The distance traveled by the particle is 467 feet.

In this problem we have the equation that represents the acceleration of a particle. The function velocity (v) is obtained by integrating the function acceleration (a) and the function position is obtained by integrating the function velocity. Now we present the definitions of each function:

Velocity

v(t) = ∫ a(t) + C

Position

s(t) = ∫ v(t) + C

Where C is the integration constant.

The distance traveled during the time interval is found means of definite integrals:

Δs = [tex]\int\limits^b_a {v(x)} \, dx[/tex]= s(b) - s(a)

a) First, determine the function velocity of the particle:

v(t) = ∫ (t + 6) dt + C

v(t) = 0.5 · t² + 6 · t + C

7 = C

v(t) = 0.5 · t² + 6 · t + 7

b) Second, determine the distance traveled in the given time interval:

Δs = s(10) - s(0)

Δs = 0.167 · 10³ + 3 · 10² + 7 - 0.167 · 0³ - 3 · 0² - 7

In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range.

The group of all outputs of a function is called its range. for example: Let's have a look at the function f: A→ B, where f(x) = 2x and A and B each represent a "collection of natural numbers. The domain in this case is A, and the co-domain is B. The range then appears as the function's output. so Set of all even natural numbers is the range.

A relation between a number of set of inputs with only one output corresponding to each of the input is called function.

Example:

Y = 2x

1. First, we have to write the function y=f(x) and then solve the equation for x and taking out equation of form x=g(y).

Suppose we have a function y=x2+1 and we have to find it range so,

we have to solve it for x to get

x=√y-1.

2. Now we have to find the domain of g(y), and this is simply the range of function f(x).

For our example,

y−1≥0, so [1,∞) is the range of f(x)=x2+1.

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

An exponential function is,

⇒ f (x) = a bˣ

And, It passes through the points (0, 3) and (3, 81).

Now,

Since, It passes through the points (0, 3) and (3, 81).

Hence, Substitute x = 0 ,  f(x) = 3 in the function,

⇒ f (x) = a bˣ

⇒ 3 = a b⁰

⇒ a = 3

And, Substitute x = 3 ,  f(x) = 81 and a = 3 in the function,

⇒ f (x) = a bˣ

⇒ 81 = 3 b³

⇒ b³ = 27

⇒ b = 3

Applying the definition of congruent triangles, the values of x and y are:

x = 11; y = 6

If two triangles are congruent, all of it corresponding parts, which are angles and sides, will have equal measure.

Since triangles RWS and TUV are congruent triangles, therefore:

<R = <T

<W = <U

<S = <V

RW = TU

WS = UV

RS = TV

Thus, find the value of x:

90 + 8x - 27 + 29 = 180

92 + 8x = 180

8x = 180 - 92

8x = 88

Divide both sides by 8

8x/8 = 88/8

x = 11

Find the value of y:

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

In this case, we have to determine is there's a uniform increase or decrease of the quantity.

The formula of proportionality is often given as

y = kx

Let's take two points and check if they share the same constant of proportionality

k = 333.33

1000 = k(3)

k = 333.33

An isosceles triangle is a triangle that has two angles in the triangle that are congruent  and two congruent sides.

The specified parameters are;

∠D is congruent to ∠E in triangle ΔDEF

The length of the segments of ΔDEF are;

DE = x + 4

EF = 4·x - 8

DF = 7·x - 35

The (base) angles ∠D and ∠F of ΔDEF are congruent, therefore, ΔDEF is an isosceles triangle (definition)

Therefore;

EF = DF (Definition of an isosceles triangle)

4·x - 8 = 7·x - 35

7·x - 4·x = 3·x = 35 - 8 = 27

3·x = 27

To write the number using only hundreds and ones we need to write our number as a linear combination of ones and hundreds, so we can write:

2,857 = a*100 + b*1

There are multiple solutions for this, we can use b to cover the ones and the tens, so:
