Answer:

To find the perimeter of this triangle, we add up all the sides together.

(8 · √3) + (8 · √3) + √384

But before we add them, let's simplify them.

(8 · 1.7) + (8 · 1.7) + 19.6

13.6 + 13.6 + 19.6

27.2 + 19.6

= <u>46.8</u>, is the perimeter of this triangle.

Now to find the area, we use the formula:

(formula for area of a triangle)

A = BH · 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.

<u><em>What we know:</em></u>

  • Base = 8 · √3 which equals <u>13.6</u>.
  • Height = 8 · √3 which equals <u>13.6</u>.

Plug in the values into our formula:-

A = BH · 1/2

A = 13.6(13.6) · 1/2

A = 184.96 · 1/2

A = 184.96/2

A = <u>92.48</u>, is the area for this triangle.

Answer:

<span>x=6</span>, <span>x=−5</span> or <span>x=9</span>

Explanation:

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.

So the zeros of <span>f<span>(x)</span></span> are precisely the values of x which make at least one of the linear factors 0, namely: 6, <span>−5</span> or 9.

Clara estimates that the length of a hiking trail is 5.75 km. She later learns that its actual length is 6.25 km. What is the pe
Hunter-Best [27]
Percent error : (approximate value - exact value) / exact value.....x 100

percent error : (5.75 - 6.25) / 6.25......ignore any negative signs
0.5 / 6.25 = 0.08.....x 100 = 8% error <==

Find a parametrization, using cos(t) and sin(t), of the following curve: The intersection of the plane y= 5 with the sphere
Elenna [48]

Answer:

The  parametrization,  of the given curve is  x = 10 cos(t) \ \ ,z = 10 sin(t)

Step-by-step explanation:

From the question we are given the function

        x^2 + y^2 + z^2 = 125

At  y= 5

       x^2 + 5^2 +z^2 =125

       x^2 + z^2 = 100

       x^2 + z^2 =  10^2

Converting the above  to it polar equation we have  

       x = 10 cos(t) \ \ ,z = 10 sin(t)

Help me with this question
Lisa [10]

Answer:

The answer is y=-x+9.

The first thing to do is find where the line intercepts the y-axis, which is at positive 9 so you'll add a +9 to the end of your equation. Next you find the slope and since it's going down left to right, you know it is a negative. Now slope is found by change in y divided by change in x. And since both change and y and change in x are both 1, 1/1 is 1. And since you know it's negative that means the slope is -x. Altogether you get y= -x+9

If Wayne buys a motorcycle for $8000. Each year the motorcycle loses 20% of its value from the previous year. How much is the mo
nexus9112 [7]
20/100 x 8000 = 1600
1600 x 3 = 4800
8000 - 4800 = 3200

The motorcycle is worth $3,200 after three years.
