Quelle et la nature d’un Triàgle TIR tel que TI=6cm IR=8cm TR =10cm

bsr

Q1

T

6 10

I 8 R

TR = 10 cm est le côté le plus long donc l'hypoténuse du triangle

SI

TR² = TI² + IR²

ALORS

TIR est un triangle rectangle en I

vous vérifiez en calculant donc TR² et TI² + IR²

Q2

si on réduit ce triangle de 0,7 => le triangle MAIS sera donc similaire => triangle rectangle aussi

Q3

vous multipliez chaque longueur de TIR par 0,7 ce qui vous donnera les longueurs de chaque côté du triangle MAIS

Step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
