Answer:

  40 units

Step-by-step explanation:

The slanted side is the hypotenuse of a triangle that is 8 units high and 6 units wide. Its length can be found from the Pythagorean theorem:

  d² = 6² + 8² = 100

  d = √100 = 10

The perimeter is the sum of side lengths. Those lengths can be found by counting grid squares. Clockwise from the upper left corner, the sum of side lengths is ...

  P = 8 + 10 + 14 + 8

  P = 40 . . . units

The X and Y coordinates (in feet) for station Shore are 2058.97 and 6980.06, respectively, and those for station Rock are 1408.03 and 6980.06, respectively. What are the azimuth, bearing, and length of the line connecting station Shore to station Rock

Answers

Answer:

Hence, the azimuth, bearing, and length of the line connecting station Shore to station Rock are [tex]270^{\circ},90^{\circ}[/tex] and [tex]650.94[/tex] feet.

Given :

The shore station point [tex](X_1,Y_1)[/tex] in feet,

        [tex](X_1,Y_1)=(2058.97, 6980.06)[/tex]

The Rock station point [tex](X_2,Y_2)[/tex] in feet

       [tex](X_2,Y_2)=(1408.03,6980.06)[/tex]

From the figure

     [tex]x=2058.97-1408.03=650.94[/tex] feet

    [tex]y=6980.06-6980.06=0\\[/tex] feet

Length of the line [tex]L=\sqrt{x^2+y^2}[/tex]

                           [tex]\Rightarrow L=\sqrt{(650.94)^2+0}=650.94[/tex]

                            [tex]\Rightarrow L=650.94[/tex] feet

[tex]\because[/tex] [tex]\tan \theta=\frac{y}{x}=\frac{0}{x}=0[/tex]

[tex]\Rightarrow \theta=\tan^{-1}(0)=0[/tex]

Azimuth of line[tex]=270^{\circ}+\theta[/tex]

                       [tex]=270^{\circ}+0[/tex]

                      [tex]=270^{\circ}[/tex]

[tex]\therefore[/tex] Bearing [tex]=360^{\circ}-\text{Azimuth}[/tex]

                [tex]=360^{\circ}-270^{\circ}[/tex]

If MK = 10 m, find the length of MKL.

Answers

The length of arc MKL in the image given is: 19.02 m.

What is the Arc Length?

Arc length = ∅/360 × 2πr, where r = 1/2(diameter of circle).

∅ = 180 + (90 - 52) = 218°

Radius (r) = 10/2 = 5 m

Arc length of MKL = ∅/360 × 2πr = 218/360 × 2π(5)

Arc length of MKL = 19.02 m

Therefore, the length of arc MKL in the image given is: 19.02 m.

PLSSS HELLPPPPP!!!!!!! Find the measure of the missing angle.

Answers

Answer:

86 degrees

Step-by-step explanation:

The total angles of a quadrilateral add up to 360 degrees, so if you do 360-134-50-90, you get 86, which is your answer.

Answer:

x is 86

Step-by-step explanation:

To solve we will use the equation s = (n-2) 180

s is the sum of all the angles, and n is the number of sides the shape has.

We do not know what s is yet, and since this is a 4 sided figure we will have to solve it like this:

s= (4-2) 180

s= 2(180)

s= 360

Since we now know all the angles added together will equal 360 we can now solve for x. We will solve by adding up all the angles together plus x like this:

134+ 90+ 50+x = 360

274 + x = 360  

-274         -274               360-274 = 86

X = 86

Find the area of an equilateral triangle with sides of length 24 inches in simplest
form?

Answers

Answer:

B. 144√3 in².

Step-by-step explanation:

Given the following data;

Sides of length = 24 inches

Mathematically, the area of an equilateral triangle is given by the formula;

A = √3 * s²/4

Where, s represents the sides of length.

Substituting into the formula, we have;

A = √3 * 24²/4

A = √3 * 576/4

A = √3 * 144

A = 144√3 in²

The price of a cell phone is usually $240 Ella mom buys one of these cell phones when the discount is 25 how much did Ella mom save?

Answers

Answer:

$60

Step-by-step explanation:

$240 = 100%

Discount = 25%

100% - 25% = 75%

75% as a decimal is 0.75

Multiply:

240(0.75) = 180

You could also do 3/4 of 240 because 0.75 is 3/4

To find out how much she saved, let's subtract the sale price from the original price:

240 - 180 = 60

Ella's mom saved $60 from the discount

x^2+ 6x + 8
Vertex:
Axis of symmetry:
Y-intercept:
X-intercept:

Answers

Answer:

( + 2 ) ( + 4 )

Step-by-step explanation:

Answer:

See below for answers and explanations (along with a graph)

Step-by-step explanation:

To calculate the vertex, we can transform the expression into an equation in the form of y=a(x-h)²+k and take (h,k) as our vertex. By completing the square, we see that y=x²+6x+8 is the same as y=(x+3)²-1, implying that our vertex is (-3,-1)

To calculate the axis of symmetry, it is defined as the vertical line that passes the x-axis, defined as x=h, therefore the axis of symmetry is x=-3

To calculate the y-intercept, it is defined as the y-value when x=0, therefore the y-intercept would be y=(0)^2+6(0)+8=8, so y=8 or (0,8)

To calculate the x-intercepts, which are the x-values when y=0, we can factor the expression and set it equal to 0 so we can use the Zero Product Property. Therefore, if x²+6x+8=0, then (x+2)(x+4)=0, implying that x+2=0 and x+4=0 are solutions. This means that our x-intercepts are x=-2 and x=-4 or (-2,0) and (-4,0).

Note that there are different ways to achieve these answers. See the graph for a visual reference (you may need to click on it to zoom in).
