Answer:
1) a = 1.6 2) f = 0.53
Step-by-step explanation:
1) 6a = 10 2) 48 = 90f
6a/6 = 10/6 90f/90 = 48/90
a = 1.6 f = 0.53
sorry i could only do the first two, i think those are right
Answer:
Step-by-step explanation:
The graph shows a linear function; the table does not. Thus, the first answer choice is incorrect.
Function g is exponential and eventually exceeds function f, which is linear; function g also has a greater average rate of change over [0, 2] than function f.
Function f has a greater y-intercept (15) than function g (8).
Answer:
y= 359 x+1500
Step-by-step explanation:
find the slope m= (2577-1859)÷(3-1) = 359
y=mx+b
find b : substitute x ,y, and m
get b = 1857 - 359*1 = 1500
Answer:
x₁ = 0.6
x₂ = 1.07
Step-by-step explanation:
36x² + 23 = 60x
36x² - 60x + 23 = 0
x = {-(-60)±√((-60²)-(4*36*23))} / (2*36)
x = {60±√(3600-3312)} / 72
x = {60±√288) / 72
x = {60±16.97) / 72
x₁ = {60-16.97} / 72 = 43.03/72 = 0.6 aprox.
x₂ = {60+16.97} / 72 = 76.97/72 = 1.07 aprox.
verify:
x₁
36*0.6² + 23 = 60*0.6
36*0.36 + 23 = 36
13 + 23 = 36
x₂
36*1.07² + 23 = 60*1.07
36*1.145 + 23 = 64.2
41.2 + 23 = 64.2
