Answer: RQS= 90, QRS= 43, QSR= 47
Solving Steps:
180-90=90 (all the angles combined equal 180)
9x-2+10x-3=90
19x-5=90
19x=90+5
19x=95
x=5
9(5)-2= 43
10(5)-3= 47
I think, the answer will be -7
We have:
f(x)=1/(x-2)
g(x)
Then:
(fg)(x)=[1/(x-2)](g(x))=g(x)/(x-2)
Now; we calculate: (fg)`(x)
Remember: (u/v)=(u`v-vu´)/v²
Therefore:
(fg)´(x)=[g´(x)*(x-2) - 1*g(x)]/ (x-2)²
We know that:
g´(1)=-1
(fg)´(1)=6
Therefore:
6=[-1*(1-2)-g(1)]/(1-2)²
6=[1-g(1)]/1
6=1-g(1)
-g(1)=6-1
g(1)=-5
Answer: B. -5
Answer:
L
Step-by-step explanation:
interior angle formula so
(number of sides - 2)*180
2*180 = 360
you can also just take an example from a square 4*90 = 360
360-121-58-70 = 111
Order of operations so multiplication then division, then subtraction and addition.
9*8 = 72
72/2 = 36
72-3 = 69
69+36 = 105
Step-by-step explanation:
Volume of water = volume of container = 12 cm * 18cm * 9 cm
so, volume of water = 1944 cm³ (since its filled full the container)
By the question in cubical container,
or, 1/3 of l³ = 1944 (formula for volume of cube is l³)
or, l³/3 = 1944
or, l³ = 5832
so, l = 18 cm
Length of each edge of cubical container is 18 cm.
