given

Let x represent the person's height.

Let x represent the streetlight's height.

Let d represent the distance between an individual and a streetlight.

Let s be the size of the shade cast by the subject.

According to the facts provided, x equals 6 feet (height of the person)

d Equals 15 feet (distance from the person to the streetlight)

The shadow's extent, s, is 15 feet.

Finding y's number, or the streetlight's height, is necessary.

The following ratios can be written using the comparable triangles property:

y / (d + s) Equals x / s

The ball is falling at 130 feet per second after 10.9375 seconds.

The height of the ball launched in the air t seconds after it is launched is given by the equation F(t) = 16t^2 – 220t + 19. We need to find the time t when the ball is falling at 130 feet per second. To do this, we need to find the derivative of the function F(t) with respect to time t, which represents the velocity of the ball at any given time t.

The derivative of F(t) with respect to t is F'(t) = 32t - 220. We can set this equal to 130 to find the time when the ball is falling at 130 feet per second:

32t - 220 = 130

32t = 350

t = 350/32

t = 10.9375 seconds

Therefore, the ball is falling at 130 feet per second after 10.9375 seconds.

Surface area = (1/2)P x s + B

where

P is the perimeter of the base,

s is the slant height, and

B is the area of the base.

By using the given values, we have:

B = (1/2) x b x h = (1/2) x 4 x 2 = 4 [tex]ft^2[/tex]

s = [tex]\sqrt{(1/2\times4)^2 + 2^2)} = \sqrt{17}[/tex] ft

P = 12 ft

B = [tex]s^2 = 12^2 = 144 \:in^2[/tex]

s = [tex]sqrt{(1/2\times16)^2 + 12^2}[/tex] = 14.4 in

P = 16 in

Surface area = (1/2) 1614.4 + 144 = 259.2 [tex]in^2[/tex]

3. By using the same formula as above, we have:

B = [tex]s^2 = 12^2 = 144\: m^2[/tex]

s =[tex]\sqrt{(1/2\times48)^2 + 12^2}[/tex] = 24 m

P = 48 m

Surface area = (1/2)4824 + 144 = 912 [tex]m^2[/tex]

4. By using the same formula as above, we have:

B = (1/2) x b x h = 90 [tex]yd^2[/tex]

s = [tex]\sqrt{(1/2*15)^2 + 12^2} = \sqrt{369}[/tex]  yd

8. The pyramid's base is a square with long sides. b = 10 m,

so the area of the base is A = [tex]b^2[/tex] = 100  [tex]m^2[/tex]

The lateral area of the pyramid is L = 4 × (1/2 × s × P/4) = 5P [tex]m^2[/tex]

Substituting the given values, we get L = 5 × 40 = 200  [tex]m^2[/tex]

A + L = 97.43 + 160 = 257.43 [tex]yd^2[/tex]

10. The base of the pyramid is a square with sides of length

b = P/4 = 16 ft/4 = 4 ft,

A = [tex]b^2[/tex] = 16 [tex]ft^2[/tex]

L = 4 × (1/2 × s × P/4) = 64 [tex]ft^2[/tex]

The total surface area of the pyramid

A + L = 16 + 64 = 80 [tex]ft^2[/tex]

11. The surface area may be computed as follows since the base is square and has sides that are each 5 feet long:

Area of each triangular face = (1/2) x s x h = (1/2) x 7 x 3.64 = 12.74 ft²

Area of the square base = b² = 5² = 25 ft²

Total surface area = 4 x (12.74) + 25 = 77.96 ft²

12. Calculate the length of the altitude by using the Pythagorean theorem:

a² + b² = c², where a = 8 ft,

b = (1/2) x b = (1/2) x 15 ft = 7.5 ft, c = h = unknown height

8² + 7.5² = c²

c ≈ 11.18 ft

Then, we can calculate the surface area as:

Area of each triangular face = (1/2) x b x h  = 83.85 ft²

Area of the triangular base = (1/2) x b x h= 60 ft²

Total surface area = 3 x (83.85) + 60 = 292.55 ft²

13. Surface area can be calculated as:

Area of each triangular face = (1/2) x s x h = 55 in²

Area of the square base = b² = 13² = 169 in²

Total surface area = 4 x (55) + 169 = 429 in²

14. The surface area can be calculated as:

Area of each triangular face = (1/2) x s x h = (1/2) x 8 x 5 = 20 m²

Area of the square base = b² = 7² = 49 m²

Total surface area = 4 x (20) + 49 = 129 m²

15. By using the Pythagorean theorem:

a² + b² = c², where a = 25 yds, b = (1/2) x b = (1/2) x 9 yds = 4.5 yds, c = h = unknown height

25² + 4.5² = c²

c ≈ 25.42 yds

Then, we can calculate the surface area as:

Area of each triangular face = (1/2) x b x h = 381.3 yd²

Area of the triangular base = (1/2) x b x h =112.5 yd²

Total surface area = 3 x (381.3) + 112.5 = 1256.4 yd²

The function that is increasing at a faster rate, given the graph shown, is D. g ( x ) increases at a faster rate.

You can find which function is increasing faster by looking at the steepness of the line.

When the slope of a line is positive, it means that as we move from left to right along the line, the y-coordinate of a point on the line increases. This indicates that the line is moving upward and becoming steeper. The steeper the line, the larger the magnitude of the slope.

g ( x ) was more steep in the interval [ 0, 1 ] and so was increasing at a faster rate.

Using the circumference formula of the circle, we know that the area of the shaded region is 2,375 in.

The circumference of a circle is the distance encircling its edge.

The diameter of a circle is the distance measured through its center.

The radius of a circle is the distance from the center to any point on the edge.

The circumference of a circle or ellipse in geometry is its perimeter.

That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

The curve length around any closed figure is more often referred to as the perimeter.

So, the circumference of the inner circle is 125.6 inches.

Then, the radius would be:

C = 2πr

125.6 = 2πr

125.6 = 6.28r

r = 125.6/6.28

r = 20 in

r for the outer circle: r will be 20 + 14 = 34 in

Area of the inner circle:

A = πr²

A = π20²

A = 1256.63706

A = 1257 in

Area of the outer circle:

A = πr²

A = π34²

A = 3631.68111

A = 3632 in

Area of the shaded region:

3632 in - 1257 in = 2,375 in

Therefore, using the circumference formula of the circle, we know that the area of the shaded region is 2,375 in.

The maximum value of the function z=8x+3y subject to the constraints y>=0, x>=4, y<=10, and 5x+2y<=60 can be found using the method of linear programming.

Graph the constraints on a coordinate plane. The constraints y>=0 and x>=4 are vertical and horizontal lines, respectively.

The constraint y<=10 is a horizontal line at y=10, and the constraint 5x+2y<=60 can be rewritten as y<=-5/2x+30 and graphed as a line with a slope of -5/2 and a y-intercept of 30.

Identify the feasible region, which is the area of the graph that satisfies all of the constraints.

In this case, the feasible region is the quadrilateral bounded by the lines x=4, y=0, y=10, and y=-5/2x+30.

Find the vertices of the feasible region. The vertices are the points (4,0), (4,10), (8,10), and (10,5).

Substitute the coordinates of the vertices into the function z=8x+3y to find the maximum value. The maximum value occurs at the vertex (8,10), where z=8(8)+3(10)=94.

Therefore, the maximum value of the function z=8x+3y subject to the constraints y>=0, x>=4, y<=10, and 5x+2y<=60 is 94.

Using some rules for interior angles, we will see that:

x = 22.5

y = 22.5

Remember that the sum of the interior angles of any triangle is 180°.

Now, we can see that :

3x + k = 180°

Where k is the missing angle in the left triangle.

k = 180° - 3x

if we add the 3 interior angles, we will get:

2x + y + 180° - 3x = 180°

y - x = 0°

So x and y have the same value.

If now use the top triangle, we can write:

(90 - y) + 3x + 2x = 180

And we know that y = x

90 -x  + 3x + 2x = 180

90 + 4x = 180

4x = 180 - 90  =90

Step-by-step explanation:

Answer:

[tex]\frac{4}{50fx^{30} } :[/tex][tex]\frac{2}{25f^{30} }[/tex]

Step-by-step explanation:

Factor thenumber:4=2\2

[tex]=\frac{2 . 2}{50fx^{30} }[/tex]

Factor the number 50= 2 x 25

[tex]=\frac{2.2}{2.25f^{30} }[/tex]

Cancel the common factor:2

[tex]=\frac{2}{25f^{30} }[/tex]

The zeros and their multiplicities are x=-2/3, multiplicity 5 and x=5, multiplicity 1.

To find the zeros of the function f(x)=(3x+2)^(5)(x^(2)-10x+25), we need to set the function equal to zero and solve for x.

0=(3x+2)^(5)(x^(2)-10x+25)

Since the product of two factors is zero, one of the factors must be zero. We can set each factor equal to zero and solve for x.

(3x+2)^(5)=0

3x+2=0

3x=-2

x=-2/3

The other factor is:

x^(2)-10x+25=0

This is a quadratic equation, which we can solve using the quadratic formula:

x=(-b±√(b^(2)-4ac))/(2a)

x=(-(-10)±√((-10)^(2)-4(1)(25)))/(2(1))

x=(10±√(100-100))/2

x=(10±0)/2

x=10/2

x=5

So the zeros of the function are x=-2/3 and x=5.

To find the multiplicity of each zero, we need to look at the exponent of the factor that contains the zero. The zero -2/3 comes from the factor (3x+2)^(5), which has an exponent of 5, so the multiplicity of -2/3 is 5. The zero 5 comes from the factor (x^(2)-10x+25), which has an exponent of 1, so the multiplicity of 5 is 1.

Therefore, the zeros and their multiplicities are:

x=-2/3, multiplicity 5

x=5, multiplicity 1

3) $13,786.40

4) $835.88

5) x = 3, y=(0, 1.5)

1) To find the number of pounds of grass seed needed to cover an area of 140,000 ft2, you need to write a proportion and solve it. Set up the proportion using the given information:

20 lb/10,000 ft2 = x lb/140,000 ft2

To solve for x, multiply both sides of the equation by 140000:

20 lb * 140000/10,000 ft2 = x lb

x = 2800 lb

You will need 2800 lbs of grass seed to cover an area of 140,000 ft2. To find out how many whole bags of seed you will need to buy, divide the total number of pounds by the number of pounds in a bag, which is 20 lbs. You will need to buy 140 whole bags of seed.

2) To solve for T2 in the equation ???????????????? ???????? = ???????????????? ????????, divide both sides of the equation by ???????????????? :

T2 = ???????????????? ????????/????????????????

3) To find the cost of the car before the sales tax, subtract the 5% sales tax from the total cost. The formula is:

Cost before tax = Total Cost - (Total Cost * Sales Tax %)

Cost before tax = $14,512 - ($14,512 * 0.05) = $13,786.40

4) To find the list price of the laptop computer, add the 15% off sale to the sale price. The formula is:

List Price = Sale Price + (Sale Price * Discount %)

List Price = $722.50 + ($722.50 * 0.15) = $835.88

5) The x and y intercepts for the equation 3x + 6y = 9 can be found by setting x or y equal to 0 and solving for the other. To find the x intercept, set y = 0:

3x + 6(0) = 9

3x = 9

x = 3

The x intercept is (3, 0). To find the y intercept, set x = 0:

3(0) + 6y = 9

6y = 9

y = 1.5

The y intercept is (0, 1.5).

We can plot these points on the graph and draw a straight line passing through them to represent the line 3y-4x=12.

What is graph ?

Graphs are visual representations of data or mathematical functions that are used to help people understand and analyze the relationships between different variables. Graphs can be used to show patterns, trends, and relationships in data that might be difficult to see from a table or list of numbers.

To draw the line 3y-4x=12 on the graph, we can solve for y and plot several points for different values of x, then connect the points with a straight line.

When x = -3:

3y - 4(-3) = 12

3y + 12 = 12

3y = 0

y = 0

So one point on the line is (-3, 0).

When x = 0:

3y - 4(0) = 12

3y = 12

y = 4

So another point on the line is (0, 4).

We can plot these points on the graph and draw a straight line passing through them to represent the line 3y-4x=12. The graph should look like this:

The domain and range of C are:
Domain of C: {c, j, e}
Range of C: {h, j, c, a}

The domain and range of a relation C are the set of all x-values and y-values in the ordered pairs of C. The domain of C is the set of all x-values, and the range of C is the set of all y-values. We can find the domain and range of C by looking at the ordered pairs in C={(c,h),(j,j),(j,c),(e,a)}.

The domain of C is {c, j, e} because these are the x-values in the ordered pairs. The range of C is {h, j, c, a} because these are the y-values in the ordered pairs.

Therefore, the domain and range of C are:
