The answer is D) SSS.
We have 3 pairs of congruent sides from each triangles, including the shared side.

Have an awesome day! :)

Answer:

<h2>D) SSS</h2>

Step-by-step explanation:

In the given image you can observe two triangles with congruent sides,

PQ \cong SQ\\PN \cong SN\\QN \cong QN

Notice that all three corresponding sides are congruent. That means,

\triangle PQN \cong \triangle SQN, by SSS postulate.

The SSS postulate states that if two triangles have all three corresponding sides congruent, then those triangles are congruent.

Therefore, the right answer is D) SSS.

In a certain number of hours a woman traveled 6 km. If she had traveled 3 km more per hour, it would have taken her 7 h less to
Licemer1 [7]
We will define the following variables to solve the problem:
 s: normal speed
 t: normal time
 We write the following system of equations:
 6 = s * t
 6 = (s + 3) * (t-7)
 Rewriting the equation two we have:
 6 = s * t -7s + 3t -21
 Substituting:
 s = 6 / t
 6 = (6 / t) * t -7 (6 / t) + 3t -21
 Multiplying both sides by t:
 6t = 6t - 42 + 3t ^ 2 - 21t
 Rewriting:
 3t ^ 2 - 21t - 42 = 0
 We take the positive root:
 t = 7/2 + root (105) / 2
 t = 8.62 h
 We look for the value of the speed:
 s = 6 / t
 s = 6 / 8.62
 s = 0.696 km / h
 Answer:
 
she did travel 0.696 kilometers per hour

If f(x) = x^2 is reflected over the x-axis and the shifted 4 units down, what is the equation of the new function, g(x)?
NARA [144]

Answer:

g(x) = -x² - 4

Step-by-step explanation:

In this case, we are only changing <em>a </em>(reflection and vertical shrink/stretch) and <em>k </em>(vertical movement)

<em>k </em>= -4 because we are moving 4 units down

<em>a </em>= -1 because we are just reflecting over the x-axis

zloy xaker [14]

Answer:

C. 2

Step-by-step explanation:

Cohen's d is a parameter used to express the standardised difference between two means. It is defined as the difference between the means divided by the pooled standard deviation.

In this case, the difference between both means (M2-M1) is 8. As for the pooled standard deviation, simply take the square root of the given pooled variance:

S=\sqrt{S^2}\\S=\sqrt{16} \\S= 4

Therefore, the value of Cohen's d (d) is:

d=\frac{M_{2} -M_{1}}{S} \\d=\frac{8}{4}\\d=2
