10.44 Percent of increase in the price of a basketball .

A percentage is a number or ratio that is expressed as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent sign, "%," is frequently used to denote it. A percentage is a dimensionless number; there is no specific unit of measurement for it.

By divided the number by the entire value and multiplying the outcome by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.

The price of basketball increased = $18.50 -$16.75 = 1.75$

Now the percent of increase in the price= 1.75/16.75×100

= 10.44%

Answer: The answer is 6.75

Step-by-step explanation:

I did the math :b

Given: f(x)=  4x 2 +1 / x

​When we differentiate both sides in relation to x, we obtain

f ′ (x)=  x(8x)−(4x² +1)/x² = 4x² −1 / x²

​(a) To improve function.

f  (x)≥0

⇒ 4x²-1/ ≥0

⇒ 4x²- 1 ≥ 0

⇒ (2x-1) (2x+1) ≥0

⇒ x ≥ 1/2 or x≤ -1/2

So, f(x) is increasing function on (-∞, -1/2] ∪ [1/2,∞)

(b) for decreasing function,

⇒ 4x²-1/x² ≤0

⇒ 4x²-1 ≤0

⇒(2x - 1) (2x+1)≤0

⇒ x ≤ 1/2 or x≥ -1/2

so, f(x) is decreasing on [-1/2, 1/2]

Between the ages of 14 and 16, g(x) increases by a factor of 64/56 = 1.1429.

A defined range of values inside a piece of data is known as an interval. It measures the spread of the data and is defined as the difference between the maximum and minimum values of the data set. Intervals can be applied in many different contexts, from tracking the evolution of data distribution to spotting trends. Additionally, outliers and unusually high or low values in a data collection can be found using intervals. In statistics, interval data are frequently used to quantify data variability.

Divide the value of g(16) by the value of g to find the factor by which g(x) increases across the range of 14 to 16. (14).

G(14) has a value of 56, and G(16) has a value of 64.

Answer:

80 months

Step-by-step explanation:

If the present monthly heating costs average $300, but the insulation is expected to reduce heating costs by 10%, then there will be a monthly saving of 10%:

[tex]\implies \rm Monthly\;saving=10\%\;of\;\$300 =\dfrac{10}{100} \times \$300=\$30[/tex]

To calculate how many months it will take to recover the cost of the insulation, divide the cost of installing the insulation by the monthly saving:

[tex]\implies \rm Number\;of\;months=\dfrac{\$2400}{\$30}=80[/tex]

Therefore, it will take 80 months to recover the cost of the insulation.

Answer:

80 months

Step-by-step explanation:

The expected monthly savings from the insulation are: $300 × 10% = $30.

So, the number of months required to recover the cost of the insulation, $2400, is $2400/$30 = 80 months.

9x² - y² = 1

use the power rule to differentiate

[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = an[tex]x^{n-1}[/tex]

[tex]\frac{d}{dx}[/tex] (y² ) = 2y [tex]\frac{dy}{dx}[/tex]

[tex]\frac{d}{dx}[/tex] ( constant ) = 0

The length of the page is √30+2in and the width of the page is √30+2in. The approximate dimensions of the page are 7.48 in × 7.48 in.

Now, According to the question:

The area of a rectangular page can be calculated using the area of a rectangle which is just the product of the length and the width of the page.

                                                         A = lw

Here, l represents the length of the page and w represents the width of the page.

Determine the dimensions of a page given that the printed area is [tex]30in^2[/tex]

and the page has margins on each side, each having a width of 1in.

We will first set up an equation using the details that we know. We know that the printed area is  [tex]30in^2[/tex] We can let x be the length of the printed area and y be the width of the printed area. Assuming that the printed area is rectangular, the area is

[tex]A_p=xy[/tex]

30 = xy

[tex]y = \frac{30}{x}[/tex]

Now, we want to minimize the amount of paper used. The length of the entire page would be x + 2 since we have to consider the 1-in margins at the top and the bottom. Similarly, the width would be y+ 2  since we have to consider the margins at the sides. The area of the page is as follows.

A = (x+2)(y + 2)

We can substitute the value of y in terms of x.

A(x) = (x + 2)([tex]\frac{30}{x} +2[/tex])

A(x) = x ([tex]\frac{30}{x}[/tex]) + 2x + 2[tex](\frac{30}{x} )[/tex] + 4

A(x) = 30 + 2x + [tex]\frac{60}{x}[/tex] + 4

A(x) = 34 + 2x + [tex]\frac{60}{x}[/tex]

We want to minimize this area, so we will apply differentiation to this function. By finding its derivative and equating it to zero, we can find the value/s of x that will minimize the area.

A'(x) = [tex]2-\frac{60}{x^2}[/tex]

0  = [tex]2-\frac{60}{x^2}[/tex]

[tex]2 =\frac{60}{x^2}[/tex]

[tex]2x^2=60\\\\x^{2} =\frac{60}{2}\\ \\x^{2} =30\\\\x =[/tex]±[tex]\sqrt{30}[/tex]

Since we are dealing with dimensions, we can only choose the positive value, x =√30. Now, to determine if this would really minimize the area of the page, we can substitute it into the second derivative of the function. If the result is positive, the value of x would give the minimum area.

A"(x) = [tex]\frac{120}{x^3}[/tex]

[tex]A"(\sqrt{30} )=\frac{120}{(\sqrt{30})^3 }[/tex]

[tex]A"(\sqrt{30} )=0.73[/tex]

We can now use the value of x to find the dimensions of the page. Take note that the dimensions of the page are x + 2 and y + 2

x + 2 = √30 + 2

y + 2 = [tex]\frac{30}{x}[/tex] + 2

y +2  = [tex]\frac{30}{\sqrt{30} }[/tex] + 2

y + 2 = [tex]\sqrt{30}+2[/tex]

Therefore, the length of the page is √30+2in and the width of the page is √30+2in. The approximate dimensions of the page are 7.48 in × 7.48 in.

$120.00 increased by 20% is $144.00

Answer:

x=$3059.00

Step-by-step explanation:

To solve this equation, we need to use the properties of exponential functions and perform some algebraic manipulations. First, we can simplify the right-hand side of the equation by combining the constant terms and the exponent on the x:

$4001.035 = $105 + x(1.03)3 + x(1.032)

Next, we can combine the x terms on the left-hand side by multiplying them out and combining the exponents:

x(1.03)3 + x(1.032) = x(1.03)3 + x(1.03)(1.03) = x(1.03)4

Now we have:

$4001.035 = $105 + x(1.03)4

To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 105 from both sides:

$3900.035 = x(1.03)4

Next, we divide both sides by 1.03^4

x = $3900.035 / (1.03)^4

x = $3,059.00

x= $3059.00 (rounded to the nearest cent)

In this problem we find the case of a person that invests a lot of money, distributed in two investments. We need to determine how much money must be invested in each plan to earn a desired return:

R = (C - c) · (r₁ / 100) + c · (r₂ / 100)

Where:

Part A - If we know that R = 9300, C = 91000, r₁ = 10 and r₂ = 11, then the amount invested in the most risky investment:

9300 = (91000 - c) · (10 / 100) + c · (11 / 100)

930000 = (91000 - c) · 10 + c · 11

930000 = 910000 - 10 · c + 11 · c

c = 20000

The person must invest $ 20000 in the least risky investment and $ 71000 in the most risky investment.

Answer:

5 cookies and 4 brownies

Step-by-step explanation:

First, let's assign variable for cookies and brownies:

x= cookies

y= brownies

Now, let's create an equation with the information given to us:

[Note: "#of brownies + 8" equals the number of cookies because, in the question, we are told He bought 8 more cookies than brownies ]

cost of a brownie * #of brownies +  cost of a cookie * (#of brownies + 8 ) = $7.50

1.25y + 0.5x = 7.5

Since we want to solve the problem graphically, let's solve our equation for y, so it can be graphed:

1.25y + 0.5x = 7.5   [Subtract 0.5x from both sides]

1.25y = -0.5x + 7.5   [Divide both sides by 1.25 so we just get y]

y = -0.4x + 6

This equation will be used to determine what we can buy at the bakery with $7.50.

Now, we will graph the equation (see attached image). What we will see is that as x increases, y decreases. This makes sence, since the number of brownies (y) you can buy with your budget decreases as the number of cookies (x) you buy increases. Lastly, since we can't buy a fraction of a cookie, we want to find a coordinate on the line that has both a natural [see definition if confused] x and y value. To do this, we will look at the graph and see if a x value of 1 gives us a natural y value. If not, we go on to 2 and see if it gives us a natural y value. This continues until you find both a natural x and y value. This will happen at x=5 and y=4. This answer tells us that, with $7.50, Qasim and his children bought 5 cookies and 4 brownies.
