Answer:

The Rosita investment worth in 2025 is $83486.4 .

Step-by-step explanation:

The expontential increase function is given by.

[tex]y = a(1 + r)^{t}[/tex]

Where a is the initial value , r is the rate of interest in the decimal form and t is the time.

As given

Rosita invested in a precious mineral.

The value of the mineral tends to increase by about 12% per year.

She invests $24,000 in 2014.

As

a = 24000

12% is written in the decimal form.

[tex]= \frac{12}{100}[/tex]

= 0.12

r = 0.12

As Rosita invested from 2014 to 2025.

Than

t = 2025 - 2014

t = 11 years

Put in the expontential increase function.

[tex]y = 24000(1 + 0.12)^{11}[/tex]

[tex]y = 24000(1.12)^{11}[/tex]

y = 24000 × 3.4786 (Approx)

y = $83486.4

Therefore the Rosita investment worth in 2025 is $83486.4 .

Answer:

true/ true/ false/ true

Step-by-step explanation:

4x² is a term in both the numerator and denominator → Correct

factorise numerator and denominator

4x² - 4 = 4(x² - 1) ← common factor of 4

x² - 1 ← is a difference of squares and factors as

(x - 1)(x + 1)

4x² - 3x - 1 = (4x + 1)(x - 1) ← in factored form

Hence (x - 1) is a common factor in the numerator and denominator → Correct

4 is only a common factor in the numerator not the denominator

the denominator has three terms → Correct

being 4x² , - 3x and - 1

Answer:

Yes (under certain conditions)

Step-by-step explanation:

Binomial probability formula can be used if there are success and failure been discussed in the question.

The formula is given by

P(X=x) = \binom{n}{x}p^{x}q^{n-x}

where n= no. trials

p  = success

q= failure

x= point at which we need to find the probability

Here, 85 customers are surveyed, then n= 85

we will take, p= live entertainment had increased the amount of money they spent (success)

q = live entertainment had not increased the amount of money they spent (failure)

x should be defined, then only we can use binomial probability formula

Example, x= 10 customers said that the money they spent increased if the live entertainment provided.

Answer:

Yes

Step-by-step explanation:

Binomial distribution is valid for trials which consist of only two outcomes, and each trial is independent of the other.

Here 85 mall customers were randomly surveyed.  We have that each customers is independent of the other for the state o determine if the live entertainment provided had increased the amount of money they spent

Hence probability for each person  to say yes  can be taken as p and q =1-p for no reply.

There are only two outcomes.  

Also n =85 is sufficiently large to have np or nq >5

Hence the probability can be found using binomial probability formula provided p = probability for success of a single trial is given.

QUESTION 1

The given function is

[tex]h(x)=-4x-72[/tex]

If [tex]x[/tex] decreases by [tex]11[/tex], then the new value is [tex]x-11[/tex].

We need to find the value the function at [tex]x-11[/tex] which is

[tex]h(x-11)=-4(x-11)-72[/tex]

This simplifies to

[tex]h(x-11)=-4x+44-72[/tex]

The increment in [tex]h(x)[/tex] is given by;

[tex]h(x-11)-h(x)=-4x+44-72-(-4x-72)[/tex]

This simplifies to,

[tex]h(x-11)-h(x)=-4x+44-72+4x+72[/tex]

This further simplifies to

[tex]h(x-11)-h(x)=44[/tex]

Therefore the corresponding increment in [tex]h(x)[/tex] is [tex]44[/tex].

QUESTION 2

The given function is

[tex]f(x)=\frac{3}{17}x+2[/tex].

If [tex]x[/tex] increases by [tex]51[/tex], then the new value of [tex]x[/tex] is [tex]x+51[/tex].

The increment in [tex]f(x)[/tex] is given by

[tex]h(x+51)-h(x)=\frac{3}{17}(x+51)+2-(\frac{3}{17}x+2)[/tex]

We expand the brackets to get,

[tex]h(x+51)-h(x)=\frac{3}{17}x+9+2-\frac{3}{17}x-2[/tex]

We simplify further to obtain,

[tex]h(x+51)-h(x)=9[/tex]

Therefore the corresponding increment in [tex]f(x)[/tex] is [tex]9[/tex].

When x decreases by 11, function h(x) increases by -100. When x increases by 51, f(x) increases by 9.

To find how much Function h(x) increases when x decreases by 11, we can calculate h(x) for the original value of x and the new value of x and then find the difference.

Original h(x) for h(x) = -4x - 72:

h(x) = -4x - 72

For x decreased by 11, the new x is x - 11:

New h(x) for h(x) = -4x - 72:

h(x - 11) = -4(x - 11) - 72

Now, we calculate the difference in h(x) values:

Δh = h(x - 11) - h(x)

Δh = [-4(x - 11) - 72] - (-4x - 72)

Now, simplify:

Δh = -4x + 44 - 72 + 4x - 72

The -4x and +4x cancel out:

Δh = 44 - 72 - 72

Now, calculate the difference:

Δh = -100

So, when x decreases by 11, h(x) increases by -100.

For the second part, to find how much f(x) increases when x increases by 51, we can use a similar approach.

Original f(x) for f(x) = (3/17)x + 2:

f(x) = (3/17)x + 2

For x increased by 51, the new x is x + 51:

New f(x) for f(x) = (3/17)x + 2:

f(x + 51) = (3/17)(x + 51) + 2

Now, calculate the difference in f(x) values:

Δf = f(x + 51) - f(x)

Δf = [(3/17)(x + 51) + 2] - [(3/17)x + 2]

Now, simplify:

Δf = (3/17)x + (3/17)(51) + 2 - (3/17)x - 2

The (3/17)x and - (3/17)x cancel out, and 2 - 2 also cancels:

Δf = (3/17)(51)

Now, calculate the difference:

Δf = 3 * 3

Δf = 9

So, when x increases by 51, f(x) increases by 9.

When the pack of 80 stickers is divided evenly among the three friends, each friend receives 26 stickers, with the remaining 2 stickers going to their teacher.

In order to find out how many stickers each friend will get from a pack of 80, we can divide the total number of stickers by the number of friends. In this case, that's 80 stickers ÷ 3 friends. This division gives us a result of 26 stickers with a remainder of 2.

However, the question states that the remainder is given to their teacher. So while the remainder division resulted in each friend getting 26 stickers with an extra 2 left over, those extra 2 stickers are given to the teacher. Therefore, each friend ends up with 26 stickers.

The width of the rectangle is calculated using the formula for the perimeter of a rectangle, P = 2l + 2w. Given a perimeter of 66 cm and a length of 24 cm, the width is found to be 9 cm.

Explanation:

The question is asking to find the width of a rectangle given the perimeter and the length. The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

To find the width, we can rearrange the formula: w = (P - 2l) / 2.

Substituting the given values into the formula:

w = (66 cm - 2 * 24 cm) / 2

w = (66 cm - 48 cm) / 2

w = 18 cm / 2

w = 9 cm

Therefore, the width of the rectangle is 9 cm.

Radical form of the  expression [tex]4^{\frac{3}{2} }[/tex] is, 8

Step-by-step explanation:

Given the expression: [tex]4^{\frac{3}{2} }[/tex]

Since,  [tex]\sqrt{4^3}[/tex] is same as [tex]4^{\frac{3}{2} }[/tex]

Now, to write an exponent in radical form,

then the  denominator or the index goes in front of the radical and

the numerator goes inside of the radical.

we raise the base to the power of the numerator then:

[tex]4^{\frac{3}{2} }[/tex] = [tex]\sqrt{64}[/tex] = [tex]\sqrt{8 \times 8}[/tex] = [tex]\sqrt{8^2} = 8[/tex]

therefore, the radical form of the given expression is, 8

Answer:

Step-by-step explanation:

We can find the surface area of the dumbbell by adding the surface areas of each part. We have two equal round ends of the dumbbell to count and the skinnier inside. Each is a cylinder and each can be found by finding the area of the base (times 2 for two bases) and adding it to the circumference times the height.

[tex]2(\pi r^{2} )+(\pi d)h[/tex]

Dumbbell Ends

There are two ends and so we will count this measurement twice. The diameter is 12.5. The radius is half of this and is 6.25. The height is 8.

[tex]2(\pi r^{2} )+(\pi d)h[/tex]

[tex]2(\pi (6.25)^{2} )+(\pi 12.5)8[/tex]

[tex]2(\pi 39.0625 )+(\pi 100[/tex]

245.4369+314= 559.43

But we must count is twice, so 559.43(2)=1118.87 cm squared.

Dumbbell Middle

The diameter is 2.50. Radius is 1.25. The height is 10.5. The ends actually don't show because they are attached. So we will only calculate the second part and add it to the other.

[tex](\pi 2.5)10.5[/tex]=82.47

82.47+1118.87=1201.33 cm squared.

Why is this too large? Why isn't it an answer choice? Because the ends of the middle don't show, they also take up that much area on other side. They are not part of the surface area and they make it smaller. So we will subtract that area now.

[tex]2(\pi 1.25^{2} )[/tex]=9.817

⇒[tex]6b=95.94[/tex]    (equation to determine cost of one box)

cost of one box 'b' = $`15.99

⇒[tex]120t = 95.94[/tex]    (equation to determine cost of per tile)

cost of one tile t = $0.7995.

Step-by-step explanation:

Given :

Jorge bought a crate of floor tiles for $95.94.

The crate had 6 boxes of floor tiles.

Each box contained 20 floor tiles .

To Find :

Write and solve equation to determine the cost per box'b'.

Write and solve a second equation to determine the cost per tile't'

Solution :

Cost of one box = b

There are 6 boxes

So, cost of 6 boxes = $  6b

Since Jorge bought 1 crate( = 6 boxes) of cost $95.94

⇒[tex]6b=95.94[/tex]     (equation to determine cost of one box)

⇒[tex]b=\frac{95.94}{6}[/tex]

⇒[tex]b=15.99[/tex]

Thus cost of one box = $`15.99

Since 1 box 20 floor tiles

So, 6 boxes (=1 crate) contain tiles = 6*20 = 120 tiles

We are given that cost of 1 crate( = 6 boxes = 120 tiles) is $95.94

Cost of one tile = t

Cost of 120 tiles = $120t

⇒[tex]120t = 95.94[/tex] (equation to determine cost of per tile)

⇒[tex]t=\frac{95.94}{120}[/tex]

⇒[tex]t=0.7995[/tex]

Thus cost of one tile t = $0.7995.

Step-by-step explanation:

(p-2)x=4-p^2

(4-p^2)/(p-2)

-2-p

The solution of the expression for the given condition would be, - (p + 2).

Used the concept of trigonometry formula which stated that,

[tex](a - b)^2 = a^2 - 2ab + b^2[/tex]

Let us assume that,

When we multiply by x in (p - 2) the solution is (4 - p²).

So, it can be written in mathematical form as,

[tex]x \times (p - 2) = (4 - p^2)\\[/tex]

[tex]x \times (p - 2) = (2^2 - p^2)\\[/tex]

[tex]x \times (p - 2) = (2 - p) (2 + p)[/tex]

[tex]x \times (p - 2) = - (p - 2) (2 + p)[/tex]

Divide both sides by (p - 2),

[tex]x = - (p + 2)[/tex]

So, we get;

[tex](p - 2) \times - (p + 2) = (4 - p^2)[/tex]
