Answer:

The length of the lot is [tex]105.6\ ft[/tex]

Step-by-step explanation:

Remember that

[tex]1\ acre=43,560\ ft^{2}[/tex]

In this problem the area of the lot  is equal to

[tex]\frac{2}{3} (43,560)=29,040\ ft^{2}[/tex]

Let

x-----> the length of the lot

y ----> the deep of the lot

The area of the lot is

[tex]A=xy[/tex]

we have

[tex]A=29,040\ ft^{2}[/tex]

[tex]y=275\ ft[/tex]

substitute and solve for x

[tex]29,040=x(275)[/tex]

[tex]x=29,040/(275)=105.6\ ft[/tex]

Answer:

80

Step-by-step explanation:

let w = the width of the rectangles

then

12w = the area of one rectangle

8w = the area of other

:

12w - 8w = 320

4w = 320

w = 320/4

w = 80 units wide

;

:

Check

12 * 80 = 960

8 * 80 = 640

--------------

difference: 320

We know that both rectangles have the same width, which is 80 units.

We know that both rectangles have the same width, so we can say that both have the width W.

One of the rectangles has a length of 12 units, and the other of 8 units, so the areas are:

A = 12*W

A' = 8*W

And the largest area is 320 square units more than the other area, so we have:

12*W = 8*W + 320

Solving for W we get:

12*W - 8*W = 320

4*W = 320

W = 320/4 = 80

Then the width of each rectangle is 80 units.

The area of a triangle is half the multiplication of the base and the height.

So, if the smaller triangle has height 6 cm and base 2 cm, its are is

[tex]\dfrac{6\times 2}{2}=6[/tex]

Similarly, if the height of the larger triangle is 9 cm, and its base is 3 cm, its area is

[tex]\dfrac{9\times 3}{2}=\dfrac{27}{2}[/tex]

So, the total area is

[tex]6+\dfrac{27}{2} = \dfrac{12}{2}+\dfrac{27}{2}=\dfrac{39}{2}[/tex]

The total area of the two triangles that need to be painted is 19.5 cm².

The total area of the two triangles that need to be painted can be found by adding the area of the smaller triangle and the area of the larger triangle. The formula to calculate the area of a triangle is:

Area = (base * height) / 2

For the smaller triangle, the base is 2 cm and the height is 6 cm. Substituting these values into the formula, we get:

Area of smaller triangle = (2 cm * 6 cm) / 2 = 6 cm²

For the larger triangle, the base is 3 cm and the height is 9 cm. Substituting these values into the formula, we get:

Area of larger triangle = (3 cm * 9 cm) / 2 = 13.5 cm²

To find the total area, we add the areas of the two triangles:

Total area = area of smaller triangle + area of larger triangle = 6 cm² + 13.5 cm² = 19.5 cm²

For this case we must find an expression equivalent to:

[tex]216 ^ {\frac {1} {3}[/tex]

So, we can rewrite the 216:

[tex]216 = 6 * 6 * 6 = 6 ^ 3[/tex]

Rewriting the expression:

[tex](6 ^ 3) ^ {\frac {1} {3}=[/tex]

By definition of power properties we have:

[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

So:

[tex]6 ^ {\frac {3} {3}} =\\6 ^ 1 =\\6[/tex]

Answer:

D. (2.4, -1).

Step-by-step explanation:

The midpoint  of the line segment with endpoints (x1,y1) and (x2,y2) is

[(x1+x2) / 2 , (y1+y1)/2 ].

So here we have : [  (3.2+1.6)/ 2 (2.5 - 4.5)/2)

= (2.4, -1) answer.

The midpoint of the line segment with endpoints (3.2, 2.5) and (1.6, -4.5) is (2.4, -1).

To find the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂), you can use the midpoint formula:

Midpoint (M) = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

For the given endpoints (3.2, 2.5) and (1.6, -4.5), we can calculate the midpoint as follows:

Midpoint (M) = ((3.2 + 1.6) / 2, (2.5 + (-4.5)) / 2)

= (4.8 / 2, -2 / 2)

= (2.4, -1)

Answer:

Domain is all real numbers; Range is all numbers less than or equal to 0

Step-by-step explanation:

Domain covers x values, range covers y values.  The domain of an x^2 parabola, which is what this is, has a domain of all real numbers.  Meaning that while the branches of the function keep going up and up and up or down and down and down, the values of x will never stop growing.

The range here is indicative of the lowest y value to the highest that the function covers.  In this case, since the parabola is upside down, we have the highest to the lowest.  The highest that the function goes up the y axis is right at the origin, where y = 0.  Then it drops down into forever.  So the range is all values of y less than or equal to 0

The Domain of [tex]f(x)[/tex] is all the real numbers, and

The Range of [tex]f(x)[/tex] is  [tex]y\le0[/tex] or [tex]f(x)\le0[/tex]

The diagram shows the graph of the quadratic function

[tex]f(x)=-x^2[/tex]

The domain of [tex]f(x)[/tex] is all the real numbers, since the function has defined values for all real values of [tex]x[/tex].

The range of [tex]f(x)[/tex] is the set of values that [tex]f(x)[/tex] can assume. The square function has a range

[tex]\{y \text{ }|\text{ }y=x^2\text{ and }y\ge0\}[/tex] or the half-open interval [tex][0,\infty)[/tex].

This means that the negative of the square function will have the range

[tex]\{y \text{ }|\text{ }y=-x^2\text{ and }y\le0\}[/tex] or the half-open interval [tex](-\infty,0][/tex].

So, the domain of [tex]f(x)[/tex] is the open interval [tex](-\infty,\infty)[/tex] (all the real numbers), and the range of [tex]f(x)[/tex] is the half-open interval [tex](-\infty,0][/tex] (or, [tex]y\le0[/tex])

Answer:

arc NO has measure 48

Step-by-step explanation:

We assume all measures are in consistent units (degrees or something similar). The two inscribed angles intercept the same arc, so are congruent:

9x -3 = 4x +12

5x = 15 . . . . . . . add 3-4x

x = 3 . . . . . . . . . divide by 5

The measure of the inscribed angle is then ...

4x +12 = 4(3) +12 = 24

That is half the measure of the arc, so the measure of arc NO is ...

arc NO = 2·24 = 48

Answer:

48°

Step-by-step explanation:

I'm actually just assuming that you mean arc NO.  Proceeding with that...

Angle NMO is an inscribed angle which intercepts arc NO.  Angle NPO is also an inscribed angle that intercepts arc NO.  Because they both intercept the same arc, both inscribed angles have the same measure.  Therefore,

9x - 3 = 4x + 12

Solving for x:

5x = 15

x = 3.  Plug 3 in for x in either one of the equations to get that angles NMO and NPO measure

9(3) - 3 = 24°

The rule is that inscribed angles measure HALF of the arcs they intercept, so the measure of arc NO is 48°

Answer:

a)

The equation of variation is;

N = 80000*S

b)

14400000

Step-by-step explanation:

We are informed that the number of instructions N performed per second by a computer varies directly as the speed S of the​ computer's internal processor. This means that N and S are directly proportional;

N∝S

Introducing a constant of proportionality, k;

N=k*S

We shall find the value of k by using the information given;

N = 1600000

S = 20

k = 1600000/20

  = 80000

a)

The equation of variation is thus;

N = 80000*S

b)

We are required to find N when S = 180

Using the equation of variation obtained above;

N = 80000 (180)

The first and fourth options are correct.

To find the angle of depression, we can use trigonometry. The elevation of the North Rim and the campground, along with the line of sight distance, can be used to calculate the angle using the tangent function.

To find the angle of depression of the man's line of sight to the campground, we can use trigonometry. The angle of depression is the angle between the line of sight and a horizontal line. In this case, the elevation of the North Rim is 5389 ft and the elevation of the campground is 2405 ft. The line of sight distance to the campground is 3044 ft.

We can use the tangent function to find the angle of depression. Tangent(theta) = opposite/adjacent. The opposite side is the difference in elevation between the North Rim and the campground (5389 ft - 2405 ft) and the adjacent side is the line of sight distance (3044 ft). So, tangent(theta) = (5389 ft - 2405 ft) / 3044 ft.

Using a scientific calculator, we can find the value of theta by taking the inverse tangent (or arctan) of the ratio: theta = arctan((5389 ft - 2405 ft) / 3044 ft). The answer is approximately 57.38 degrees.

Answer:

A = 32°, a = 19, b = 14, B=22.98°, C = 125.02°, c = 29.36

Step-by-step explanation:

We have two sides of the triangle and we have an angle.

A = 32 °, a = 19, b = 14

We use the sine theorem to find the angle B.

We know that according to the sine theorem it is true that:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

[tex]\frac{sin(32\°)}{19}=\frac{sin(B)}{14}[/tex]

[tex]sin(B)=14*\frac{sin(32\°)}{19}\\\\B=Arcsin(14*\frac{sin(32\°)}{19})\\\\B=22.98\°[/tex]

We know that the sum of the internal angles of a triangle is always equal to 180.

So:

[tex]C=180-32-22.98\\\\C=125.02\°[/tex]

Finally we find the c side

[tex]\frac{sin(A)}{a}=\frac{sin(C)}{c}[/tex]

[tex]\frac{sin(32\°)}{19}=\frac{sin(125.02)}{c}[/tex]

[tex]0.02789=\frac{sin(125.02)}{c}[/tex]

[tex]c=\frac{sin(125.02)}{0.02789}\\\\c=29.36[/tex]
