120
Step-by-step explanation:
Hello
The concept is factorial number !
Then,
5! = 5*4*3*2*1
5! = 120

Answer:
Step-by-step explanation:
a) ΔACD ~ ΔABE so the ratios of corresponding sides are the same. That is ...
CD/BE = CA/BA
CD/3.8 = 12.3/8.2
CD = 3.8×12.3/8.2 = 5.7 . . . . cm
__
b) As above, the ratios of corresponding sides are the same.
ED/AD = BC/AC
ED/9.15 = (12.3-8.2)/12.3 . . . . BC = AC - AB
ED = 9.15×4.1/12.3 = 3.05 . . . . cm
Since you are subtracting 2 logs, you write the single log as a quotient.
Answer:
"1. (−3, −7)"
Step-by-step explanation:
If we have a point (x,y),
1. Reflection across x axis makes it (x, -y)
2. Reflection across y axis makes it (-x, y)
So we see x-axis reflection simply changes sign of y coordinate & y-axis reflection changes the sign of x coordinate (keeping x and y same, respectively).
Thus, the question asks to reflect (-3,7) about x-axis, so we change sign of y coordinate, 7 becomes -7. THus, the point becomes:
(-3,-7)
Answer choice #1 is right.
