Find the surface area of the composite figure. Round to the nearest tenth if necessary.

Answer:

Step-by-step explanation:

\(a^2 +b^2 = c^2\)

So,

\(17^2 +15^2 = ?\)

Well,

\(17^2 =289\)

and

\(15^2=225\)

So,

\(289+225=514\)

Now, we have to find the square root of 514.

\(\sqrt{514} =22.671568097509267786240958185847\) OR \(22.7\)

Answer:

The shape of the Earth's surface - unevenness of the land surface - heights and slopes

To find the rate at which the diameter of the circle is changing, we'll first need to determine the relationship between the area of the circular ripple and its radius.

The area of a circle is given by the formula A = πr². In this problem, the area is increasing at a constant rate of 5 m²/second (dA/dt = 5).

Now, we'll use implicit differentiation with respect to time (t) to find the rate of change of the radius:

dA/dt = d(πr²)/dt

5 = 2πr(dr/dt)

Since we're interested in the rate of change of the diameter (D) when the radius (r) is 4 m, and D = 2r, we'll differentiate D with respect to time:

dD/dt = 2(dr/dt)

Now, we can solve for (dr/dt) when r = 4:

5 = 2π(4)(dr/dt)

5/(8π) = dr/dt

Finally, we find dD/dt:

dD/dt = 2(5/(8π))

dD/dt = 5/(4π)

So, when the radius of the circular ripple in the pond is 4 m, the diameter is changing at a rate of 5/(4π) meters per second.

30 ÷ (15÷2.5) + 7

Given: 16 · (4.5 + 3) ÷ 10= ____

First let us do PEMDAS (Parenthesis, Equation, Multiply, Divide. Add, Subtract) upon the given value.

16 · (7.5) ÷ 10 = ____

       120 ÷ 10 = ____

                     = 12

We now understand that the given is equal to the value of 12, now we will calculate each equation with PEMDAS until we find the equivalent value.

20.8 + (3 · 4) ÷ 4 =

   20.8 + 12 ÷ 4   =

          20.8  +  3  =

                            = 23.8

24 ÷ (8 − 4) + 8.2 =

       24 ÷ 4 + 8.2 =

               6 + 8.2 =

                            = 14.2

30 ÷ (15 ÷ 2.5) + 7 =

            30 ÷ 6 + 7 =

                     5 + 7 =

                              = 12

36 ÷ (9 − 4.2) + 3 =

       36 ÷ 4.8 + 3 =

                7.5 + 3 =

                            = 10. 5

It is safe to say the following:

16 · (4.5 + 3) ÷ 10 ≠ 20.8 + (3 x 4) ÷ 4

16 · (4.5 + 3) ÷ 10 ≠ 24 ÷ (8 − 4) + 8.2

16 · (4.5 + 3) ÷ 10 = 30 ÷ (15 ÷ 2.5) + 7

16 · (4.5 + 3) ÷ 10 ≠ 36 ÷ (9 − 4.2) + 3

Therefore, the answer is:

16 · (4.5 + 3) ÷ 10 = 30 ÷ (15 ÷ 2.5) + 7

Answer:

x = -7/11, y = -14/11

Step-by-step explanation:

2x = y ------- (1)

7y = -7+3x -------- (2)

from (1)

2x = y

y = 2x ------- (3)

substitute (3) into (2)

7y = -7+3x

7(2x) = -7+3x

14x = -7+3x

14x-3x = -7

11x = -7

x = -7/11

substitute x = -7/11 into (3)

y = 2x

y = 2(-7/11)

y = -14/11

x = -7/11, y = -14/11

Answer:

4.6

Step-by-step explanation:

The distance run on day 3 is about 5.9 miles.

If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).

The data points given are:

(1,2.5), (2,4.2), (4.5,6), (6,7), (8,8.1), (10,11)

Note that the growth seems to be linear, therefore, find a linear equation for the data.

Use (1,2.5) and (2,4.2) to find the slope of the line:

m = (4.2-2.5)/(2-1)

m = 1.7

The equation of the line with slope m = 1.7 and passes through point (1, 2.5) is:

y - 2.5 = 1.7(x - 1)

y = 1.7x - 1.7 + 2.5

y = 1.7x + 0.8

Substitute x = 3 into the above equation:
y = 1.7(3) + 0.8

y = 5.9

Hence, the distance run on day 3 is about 5.9 miles.

The expression -\(cot(B) * (1 - cos^2(B)) * (1 - sin(B))/(1 + sin(B))\) can be simplified by using trigonometric identities and algebraic manipulations.

To simplify the given expression, let's break it down step by step:

Start with the expression -cot(B) * (1 - cos^2(B)) * (1 - sin(B))/(1 + sin(B)).

Use the Pythagorean identity: cos^2(B) + sin^2(B) = 1. Replace cos^2(B) with 1 - sin^2(B) in the expression.

Simplify the expression to: -cot(B) * \((1 - (1 - sin^2(B))) * (1 - sin(B))/(1 + sin(B)).\)

Further simplify: -\(cot(B) * sin^2(B) * (1 - sin(B))/(1 + sin(B)).\)

Expand the expression: -\(cot(B) * sin^2(B) * (1 - sin(B))/(1 + sin(B)).\)

Cancel out the common factor of \((1 - sin(B))/(1 + sin(B)): -cot(B) * sin^2(B).\)

So, the simplified expression is -cot(B) * sin^2(B).

In summary, the given expression -cot(B) * (1 - cos^2(B)) * (1 - sin(B))/(1 + sin(B)) simplifies to -cot(B) * sin^2(B) by applying the Pythagorean identity and simplifying the resulting expression.

The dimensions of the area covered by flowers are

Since the garden is a 12-foot-by-9-foot fenced area has walking paths along one of the long sides and one of the short sides with a uniform width x.

Since the garden is a rectangle, its area is A = LW where

So, A = LW

= 12 ft × 9 ft

= 108 ft²

Also, since flowers are planted on the remaining side of the garden with a path of width x on on side, we have that the dimensions of the area covered by flowers is

Since the planted part is rectangle, its area is A' = L'W' where L' 12 - x and W'= 9 - x

So, A' = L'W'

= (12 - x)(9 - x)

Since it is given that he part covered by flowers is half of the entire enclosed area, we have that

A' = A/2

(12 - x)(9 - x) = 108 ft²/2

(12 - x)(9 - x) = 54

Expanding the brackets, we have

108 - 21x + x² = 54

x² - 21x + 108 - 54 = 0

x² - 21x + 54 = 0

Using the quadratic formula, we find x

So, \(x = \frac{-b +/- \sqrt{b^{2} - 4ac} }{2a}\)

where a = 1, b = -21 and c = 54

Substituting the values of the variables into the equation, we have

\(x = \frac{-(-21) +/- \sqrt{(-21)^{2} - 4\times1\times54} }{2\times1}\\= \frac{21 +/- \sqrt{441 - 216} }{2}\\= \frac{21 +/- \sqrt{225} }{2}\\= \frac{21 +/- 15 }{2}\\= \frac{21 + 15 }{2} or x = \frac{21 - 15 }{2}\\= \frac{36}{2} or x = \frac{6}{2}\\x = 18 or x = 3\)

Since x cannot be greater than the greatest dimension, we choose x = 3.

To model the total amount of money Victoria will have in her bank account as interest accrues after she deposits her $200, we can combine the two functions h(x) and s(x).The function h(x) represents the initial amount of money Victoria has saved at home, which is $200. The function s(x) represents the interest rate of the savings account, where x represents the number of years the money is left in the account. So, if Victoria deposits her $200 into the savings account and leaves it there for x years, the amount of money in her account will be:h(x) + h(x) * s(x)Substituting the values for h(x) and s(x), we get:$200 + $200 * (1.05)x-1This is the total amount of money Victoria will have in her bank account as interest accrues after she deposits her $200. The function combines the initial amount of money saved with the interest rate of the savings account over time, as represented by the function s(x). The interest rate is compounded annually, which is why the function s(x) uses an exponent of x-1.Therefore, Victoria can use this function to calculate the amount of money in her bank account after depositing her $200 and leaving it in the savings account for a certain number of years.

The possible dimensions ( width and length) plot of land are 9.5 m and 19 m.

A rectangle is a confined two-dimensional structure with four sides, four corners, and four right angles (90°). A rectangle's opposite sides are equal as well as parallel.

Area of a rectangle

area of rectangle = l×w

where, l = length and w = width.

Thus, the perimeter for 2 side of width and 1 side of length is;

perimeter = 2w+ l

Perimeter of river = 38 m.

38 = 2w + l

l = 38  - 2w

Hence, Put the value of l in the area.

area = w(38 - 2w)

The area of the land is 140 sq.m.

140 = 38w - 2w²

-2w² + 38w - 140 = 0

-w² + 19w - 70 = 0

The equation is in the form of quadratic. Thus use the relation of coefficients and the roots to evaluate the width.

w = - b / a

Comparing the coefficients;

where,

a = -1

b = 19

w = - 19 / 2( -1)

w = 9.5 meters

Then,

l = 38  - 2w

l = 38 - 2(9.5)

l = 19 meters

Therefore, the dimensions of the plot of land are 9.5 meters and 19 meters.
