So if the equation is (4z-5)^10 times (4-9z)^8 then you just do the exponents first and get a really big number and lots of stuff, the distributeive property doesn't apply to this
the distributive property is a(b+c)=ab+ac
Answer: f(t)=h(t)+d(t)
f(t)=-16t^2+15t+6
Step-by-step explanation:
I just got this question right
I believe it is 9. I think they are asking that if you plug in the y coordinate 0, and therefore it is asking what the value of x should be so that 2/3x-6 would equal 0. If you plug in 9, you get 18/3 and if you subtract 6 from that, you should get 0
Hi there!
~
cosec 20 -cot 40= 1/sin 20 - cos 40/sin 40
= (sin 40 -cos 40 sin20)/(sin 40 sin 20)
= 1/sin 40 ( 2 cos 20 - cos 40)
=1/sin20 ( 2 cos(60-40)-cos 40)
=1/sin40( 2 cos 60 cos 40 - 2 sin 60 -sin 40-cos 40)
Put the value of cos 60
= 1/sin 40 ( 2 sin 60 sin 40)
=root(3)
Hope this helped you!
