Answer:

Option A

Step-by-step explanation:

In the given right angle triangle ABC,

BC = 15 m and m∠A = 55°

We have to calculate the measure of side AC.

Since tanA = \frac{Height}{Base}

tan55 = \frac{15}{AC}

1.428 = \frac{15}{AC}

1.428(AC) = 15

AC = \frac{15}{1.428}

AC = 10.5 m

Therefore, Option A. AC = 10.5 m is the answer

Answer:

\sqrt{80}

80 is the number in the square root

Step-by-step explanation:

d = \sqrt{(x_{2}-x_{1}  )^{2} +(y_{2}-y_{1}  )^{2} } \\d = \sqrt{(4-(-4)  )^{2} +(5- 1 )^{2} }\\d = \sqrt{(4+4  )^{2} +4^{2}\\d = \sqrt{8^{2} +4^{2} }\\d=\sqrt{64 +16}\\d=\sqrt{80}

Which graph represents a function with an initial value of 1/2
melisa1 [442]
<span>The initial value is the value of the y-coordinate when the x-coordinate is equal to 0. That is the same to say the value at which the graph intercepts the y-axis. So, you justt have to pick the graph whose line intercepts the y-axis at 1/2. </span>

Answer:

To find the scale factor, all you have to do is <em>divide a side value of one figure by its congruent side value on another figure. </em>

Step-by-step explanation:

To start:

  • The values 15 and 10 are both for the same congreunt side --> EF and E'F'
  • The values 4 and 6 are both for the same congreunt side --> DE and D'E'
  • The values 4 and 6 are both for the same congreunt side --> DG and D'G'
  • The values 8 and 12 are both for the same congreunt side --> FG and F'G'

So, to find the scale factor, all you have to do is divide the smaller congruent value from the larger congruent value.

Larger congruent value ÷ smaller congruent value = scale factor

              15                      ÷                10                        = scale factor

              \____________________/

                                    1.5

<h3>So, the scale factor is 1.5</h3>

To double check, we will use another congruent side to find the scale factor:

12 ÷ 8 = scale factor

1.5      = scale factor

<h3>So, the scale factor is most definitely 1.5</h3>

I hope this helps!
