5w−23<−3(3−4w)
Simplify both sides of the inequality.
5w−23<12w−9
Subtract 12w from both sides.
5w−23−12w<12w−9−12w
−7w−23<−9
Add 23 to both sides.
−7w−23+23<−9+23
−7w<14
Divide both sides by -7.
−7w/−7 < 14/−7
w > −2
24.2 / 550 = 0.044
The relative error is plus or minus 4.4 percent .
Keep the base the same and add your exponents 7^11
Answer:
Step-by-step explanation:
Parameterize the ellipse as (acos∙,bsin∙). Take points P:=(acosp,bsinp) and Q:=(acosq,bsinq) on the ellipse, with midpoint M:=(P+Q)/2.
If |PQ|=2k, then
a2(cosp−cosq)2+b2(sinp−sinq)2=4k2
The coordinates of M are
xy==a2(cosp+cosq)b2(sinp+sinq)
I don't know if you still need help. but the answer is the first one.
