Scientists find a wooden spoon and they want to use Carbon dating to out how old it is. If the amount of carbon left is 85% of its original amount, how old this artifact? (Note here that we are actually finding the age of the wood from which the spoon was made
Answer:
1,336 year (Approx)
Step-by-step explanation:
Half life of carbon 14 = 5,700 year
Equation used for carbon dating:
t = [5,700/In2]ln[N]
t = [5,700/In2]ln[85%]
t = [5,700/In2]ln[0.85]
t = 1,336 year (Approx)
Find the 82nd term of the arithmetic sequence -10,6,22
Answer:
a(82) =1286
Step-by-step explanation:
a(n) = a +(n-1)d
a=-10
d=6+10=22-6=16
°.° a(n) = -10 +(n–1)16
a(82) = -10 +(82–1)16
=-10+(81x16)
=1286

find the equation for the parabola with vertex (4,6) and focus (4,9) .
Answer:
Equation of the parabola: 12y−72=(x−4)212y−72=(x−4)2 or y=x212−2x3+223y=x212−2x3+223.
Vertex form: y=(x−4)212+6y=(x−4)212+6.
No intercept form.
Vertex: (4,6)(4,6).
Focus: (4,9)(4,9).
Eccentricity: 11.

What is the y-intercept when a line has a slope of 7 and passes through
the point (-1, -3)?
Answer:
The y-intercept would be -3
Step-by-step explanation:
already learn that
Which is the equation of a line that has a slope of -5 and passes through point (-3,-1)? O y=-3x+1 O y=-3x+3 O y=-x-1 O y=-x-3 3
Note: Your answer choices are not clear, thus I have solved the complete question which anyways should be able to clear your concept.
Answer:
The equation of a line that has a slope of -5 and passes through the point (-3,-1) will be:
y = -5x - 16Step-by-step explanation:
Given
slope = m = -5point = (-3, -1)We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Here:
m is the slopeb is the y-interceptNow, substituting m = -5 and (-3, -1) in the slope-intercept form of the line equation to determine the y-intercept 'b'
[tex]y=mx+b[/tex]
-1 = -5(-3) + b
switch sides
-5(-3) + b = -1
15 + b = -1
b = -1 - 15
b = -16
Now, substituting m = -5 and b = -16 in the slope-intercept form of the line equation to determine the equation of a line
[tex]y=mx+b[/tex]
y = -5x + (-16)
y = -5x - 16
Therefore, the equation of a line that has a slope of -5 and passes through the point (-3,-1) will be:
y = -5x - 16Note: Your answer choices are not clear, thus I have solved the complete question which anyways should be able to clear your concept.
