The perimeter of the equilateral triangle is 21/4 inches.

Given,

An equilateral triangle has three congruent sides that measure 1 and 3/4 inches on each side.

We need to find what is the perimeter of the triangle.

<h3 /><h3>What is an equilateral triangle?</h3>

An equilateral triangle is a triangle where all sides are equal.

Perimeter is given by :

= 3side

Find the sides of the equilateral triangle.

Side = 1 and 3/4 inches

       = 7/4 inches

     

Find the perimeter of the equilateral triangle

Perimeter = 3 x side

                 = 3 x 7/4 inches

                 = 21/4 inches

Thus the perimeter of the equilateral triangle is 21/4 inches.

Using the triangle below, answer the following questions.

Step-by-step explanation:

<u>Answer(1):</u>

Law of Cosines.


<u>Answer(2):</u>

since side "c" is missing so we will write formula used for side "c"

c^2=a^2+b^2-2ab\cdot\cos\left(C\right)


<u>Answer(3):</u>

First lets write both sine and cosine formulas:

Check the attached picture for the list of formulas:

From given picture we see that two angles A and B are missing. Also 1 side "c" is missing.

Sine formula uses two angles while cosine formula uses only one angles.

Hence cosine formula will be best choice to find the missing values.

Find the slope of the line that passes through the pair of points
BlackZzzverrR [31]

Answer:

undefined

Step-by-step explanation:

To find the slope through 2 points

m = ( y2-y1)/(x2-x1)

   = ( -4 - -3)/(3 - 3)

    = ( -4+3)/(3-3)

    = -1/0

Since it is a number divided by zero, the slope is undefined

The circumference of ruby's old swimming pool is 47.1 feet. Her new swimming pool has a diameter of 21 feet. How much larger is
Alla [95]

The new pool is 18.84 feet larger in circumference than the old one.

<u>Explanation:</u>

Given:

Circumference of the pool = 47.1 feet

Diameter of the new pool, d = 21 feet

radius, r = 21/2 feet

Circumference of the new pool = ?

We know:

Circumference = 2πr

where,

r is the radius

On substituting the value:

C = 2 X 3.14 X \frac{21}{2}

C = 65.94 feet

The difference in circumference of the two pools = 65.94 - 47.1 feet

                                                                                  = 18.84 feet

Therefore, the new pool is 18.84 feet larger in circumference than the old one.

Choose the function whose graph is given by:
wolverine [178]

<em>Greetings from Brasil...</em>

In a trigonometric function

F(X) = ±UD ± A.COS(Px + LR)

UD - move the graph to Up or Down (+ = up | - = down)

A - amplitude

P - period (period = 2π/P)

LR - move the graph to Left or Right (+ = left | - = right)

So:

A) F(X) = COS(X + 1)

standard cosine graph with 1 unit shift to the left

B) F(X) = COS(X) - 1 = -1 + COS(X)

standard cosine graph with 1 unit down

C) F(X) = COS(X - 1)

standard cosine graph with shift 1 unit to the right

D) F(X) = SEN(X - 1)

standard Sine graph with shift 1 unit to the right

Observing the graph we notice the sine function shifted 1 unit to the right, then

<h3>Option D</h3>

<em>(cosine star the curve in X and Y = zero. sine start the curve in Y = 1)</em>
