Answer:
35/4 =8¾
Step-by-step explanation:
using pythagoras theorem
hyp²=opp²+adj²
recall that tanX= opp/adj
taking our opposite side to be 3 and the adjacent side to be 4 , the hyp² = 3²+4²
hypotenuse = 5
recall also that , sinX = opposite /hypotenuse
= 3/5
CosX= adjacent /hypotenuse
=4/5
so we've known tanx = 3/4 cosX = 4/5 sinx= 3/5
substitute these values into your equation
it will give us 3/5 + 4/5 divided by 4/5 ×(1-4/5)
=35/4 = 8¾
Answer:
0.76
Step-by-step explanation:
-8+3=-6x^(2/3)
-5=-6 x^(2/3)
-5/-6=x^(2/3)
(2/3)√{5/6}=x
0.76=x
x=0.76
Answer:
y=-13
Step-by-step explanation:
Plugging in -7:
y= (-7)2 + 1
-7 * 2 = -14
So:
y= -14 + 1
-14+1=-13
