AI = 32,36 m
IE = 30,78 m
Explication étape par étape:
Utilisation de Pythagore:
Cosθ = adjacent / hypoténus
AI = hypoténus
θ = 72 °
Adjacent = 10 m
Cos 72 = 10 / AI
0,3090169 = 10 / AI
AI = 10 / 0,3090169
AI = 32,36 m
De la trigonométrie;
IE = opposé
Adjacent = 10m
Tanθ = opposé / adjacent
Tan 72 = IE / 10
IE = Tan 72 * 10
IE = 3,0776835 * 10
IE = 30,78 m
Answer:
Let f(x) = x^3 -6x^2 +11x-8+K
by factor theorem, f(3)=0
27-54+33-8+K=0
K=2
hope that helps?
Step-by-step explanation:
Answer:
<h3>p(+)q=SQR(p^2+q^2)</h3>
8(+)6=SQR(8^2+6^2)
SQR(64+36)
SQR(100)
=10
Step-by-step explanation:
p + Q is equal to square root of p square + Q Square
sqr means square root
Plug in -2 for x for every function and set every function to 0. If it equals 0 then there's a "zero" at x=-2
Example A: 0 = (-2+2)^2 - 5 = 0 - 5 = -5 <-- This does not = 0 so it's not the answer
