Question 7. y = -2x + 7. y = mx + b; m= slope (-2) (3, 1) resolve for y. you have : 1= -2 (3) + b; 1 = -6 + b; 1 + 6 = b; b = 7.
Answer:
i am not sure but have a great night
Step-by-step explanation:
For B, the equation for circumference is pi multiplied by diameter. So, 10 * 2 = 20, and 20*3.14 is 62.8 cm
For C, assuming that "approximate" means that they used 3.14 for pi, then 81.64 / 3.14 = 26, and 26 / 2 = 13 cm
Answer:7.40 meters
Step-by-step explanation:
I went with 163 cm for the height as that is where the eyeline is and where she would be looking from. (h for hawk btw)
All you do is:
tan(30)=h/10
10*tan(30)=h
h≈5.77 meters
163cm is 1.63 meters, so add it to 5.77 and you will get 7.40
