Answer:
The other number is 120.
Step-by-step explanation:
30×360 =90xx
x=(30×360)/90
x=120
(HCFXLCM= Product if the two
numbers)
2e^(x+3)=10
e^(x+3)=5
ln[e^(x+3)]=ln 5
(x+3)ln e=ln 5
(x+3)=ln 5
x=(ln 5)-3
Answer: x=(ln 5) - 3
Answer:
y=6/5-5
Step-by-step explanation:
first find your <em>y-intercept</em> which is -5
then find your <em>slope</em> which is 6/5
and set your equation up as y=mx+b
which means <em>y equals slope times x plus your y-intercept.</em>
so your answer is
y=6/5x-5
The following choices describe exponential growth:
1) The number of butterflies in an area increases by 10% per year.
3) Kristy bought a collector's coin for $2.15 and its value increases at a rate of 3% per year.
Step-by-step explanation:
Root of the function, where y = 0
f(x) = x² + 2x - 1
0 = x² + 2x - 1
x² + 2x - 1 = 0
x² + 2x = 1
x² + 2x + 1 = 1 + 1
(x + 1)² = 2
x + 1 = ±√2
x = -1 ± √2
Roots → x = -1 ± √2
