Answer:

DE = 39.64840676

CE = 35.3269891

Step-by-step explanation:

SOH CAH TOA

Thus,

sin(27) = 18/DE

tan(27) = 18/CE

DE = 39.64840676

CE = 35.3269891

Answer:

a) The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].

b) The approximate distance between the high school and the stadium is 32 miles.

Step-by-step explanation:

a) The rest stop is located in the midpoint of the line segment between the high school and the stadium. Vectorially speaking, we use the following formula:

[tex]C(x,y) = \frac{1}{2}\cdot A(x,y) + \frac{1}{2}\cdot B(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Coordinates of the high school.

[tex]B(x,y)[/tex] - Coordinates of the stadium.

[tex]C(x,y)[/tex] - Coordinates of the rest stop.

If we know that [tex]A(x,y) = (3, 4)[/tex] and [tex]B(x,y) = (7,1)[/tex], then the coordinates of the rest stop are, respectively:

[tex]C(x,y) = \frac{1}{2}\cdot (3, 4) + \frac{1}{2}\cdot (7, 1)[/tex]

[tex]C(x,y) = \left(\frac{3}{2}, 2 \right) + \left(\frac{7}{2}, \frac{1}{2} \right)[/tex]

[tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex]

The coordinates of the rest stop is [tex]C(x,y) = \left(5, \frac{5}{2} \right)[/tex].

b) The approximate distance between the high school and the stadium ([tex]d[/tex]), in miles, is the product of the Length Equation of the Line Segment and the scale factor:

[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex] (2)

Where:

[tex]r[/tex] - Scale factor, in miles.

[tex]\Delta x[/tex], [tex]\Delta y[/tex] - Horizontal and vertical distances between the high school and the stadium, no unit.

If we know that [tex]r = 6.4\,mi[/tex], [tex]\Delta x = 4[/tex] and [tex]\Delta y = -3[/tex], then the distance between the high school and the stadium is:

[tex]d = r\cdot \sqrt{(\Delta x)^{2} + (\Delta y)^{2}}[/tex]

[tex]d = (6.4\,mi)\cdot \sqrt{4^{2}+(-3)^{2}}[/tex]

[tex]d = 32\,mi[/tex]

The approximate distance between the high school and the stadium is 32 miles.

Answer:

∠C=39°

Step-by-step explanation:

The interior angles of a triangle will always have a sum of 180°.

∠A+∠B+∠C=180°

78°+63°+∠C=180°

∠C=180°-78°-63°

∠C=39°

Answer:

39 degrees

Step-by-step explanation:

All triangles will add up to 180 degrees. So, you know that angle C added with angles A and B will equal 180. if you take 180, minus 78, minus 63, you get the answer 39.

that's 3 unit s so because it's 3.5 but round it up and u get 3

Answer:

68.8 metres

Step-by-step explanation:

First, you are given the area of a square, which is 295.84 m^2. The formula for an area of a square is Area = [tex]s^{2}[/tex], where s is the length of one side of the square.

So, if you know that the area of the square is 295.84, you can find the length of one side.

Area = [tex]s^{2}[/tex]

295.84 = [tex]s^{2}[/tex]

To solve for s, you can square root each side. [tex]\sqrt{ 295.84}[/tex] = 17.2, so the length of one side of a square is 17.2 metres.

To get the perimeter, all you have to do is multiply the length of one side of the square by 4, since a square has 4 equal sides.

So, 4 x 17.2 = 68.8 metres.

Answer:

So, if the center is (0,0) and the radius is 6, an equation of the circle is: (x-0)2 + (y-0)2 = 62.

Step-by-step explanation:

please mark this answer as brainliest

The equation in standard form for the circle with radius 6 centered at the origin will be x² + y² = 36.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle and the location of the center of the circle be (h, k).

Then the equation of the circle is given as,

(x - h)² + (y - k)² = r²

The radius of the circle is 6 units and has a center at the origin. Then the equation is given as,

(x - 0)² + (y - 0)² = 6²

x² + y² = 36

The equation in standard form for the circle with radius 6 centered at the origin will be x² + y² = 36.

Answer:

$29.75

Step-by-step explanation:

Usually, teachers usually teach you a different way to calculate this, but I found a shortcut that is useful:

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

100 - 15 = 85

Convert 85% into a decimal (0.85)

35 × 0.85 = 29.75
