Answer:

8, 20 and 6

Step-by-step explanation:

A coefficient is the numerical part of an algebraic term. Example: in the term 2x the coefficient is 2.

Find the y-intercept and slope of the function’s graph, and find the equation for the function using the table in the picture.
KengaRu [80]

m = (y2-y1)/(x2-x1)

m = (9-5)/(3-2)

m = 4

Substitute the values in y= mx + c,

5 = (4)(2) + c

5 = 8 + c

c = -3

Thus, the equation is y= 4x -3

(a) consider the initial-value problem a=ka,a(0)=ao as t as the model for the decay of a radioactive substance. show that, in ge
mina [271]

The initial-value problem dA/dt = kA, A(0) = A₀ is used to represent the radioactive decay. The radioactive substance having half-life T= -(ln 2)/k,will take 2.5 T for the substance to decay from A₀ to A₀ / 6 .

a.) To solve this, we have the following differential equation:

dA/dt = kA

With the initial condition A(0) = A₀

Rewriting the differential equation like this:

dA/A = kdt

And if we integrate both sides we get:

ln |A| = kt + c₁

Where  is a constant. If we apply exponential for both sides we get:

A=e^{kt}e^{c} = C e^{kt}

Using the initial condition A(0) = A₀ we get ,

A₀ = C

So the solution for the differential equation is given by:

A(t) = A_{0}e^{kt}

For the half life we know that we need to find the value of t for where we have,

A(t) = 1/2 (A₀)

Using this we get ,

\frac{1}{2}A_{0} = A_{0}e^{kt

Cancel A₀ on both sides and applying log on both sides we get ,

ln(1/2) = kt

t = {ln(1/2) / k } ----(1)

And using the fact that  ln(1/2) = -ln(2)  we get,

t = - { ln(2) / k }

b.) To solve this we consider ,

A(t) = A_{0} e^{kt}

Replacing k with value obtained from 1 we get,

k = - {ln(2) / T}

A(t) = A_{0}e^{\frac{ln(2)}{T}t

Cancel the exponential with the natural log, we get,

A(t) = A_{0} 2^{-\frac{1}{T} }

c.)For this case we find the value of t when we have remaining A₀/6

So we can use the following equation:

A₀/6 =A_{0}2^{-\frac{t}{T} }

Simplifying we got:

1/6 = 2^{-\frac{t}{T} }

We can apply natural log on both sides and we got:

ln (1/6) = -t/T{ln(2)}

And if we solve for t we got:

t = T { ln(6) / ln(2) }

We can rewrite this expression like this:

t = T { ln(2²°⁵) / ln(2) }

Using properties of natural logs we got:

t = 2.5T { ln(2) / ln(2) }

t = 2.5T

Thus it will take 2.5 T for the substance to decay from A₀ to A₀/6

A cone has a radius of 24 cm and a volume of 1,920 cm cubed. What is the Volume of a similar cone with a radius of 18 cm?
Maurinko [17]
24 * 3/4 = 18

The radius of smaller cone is 3/4 the radius of original cone, so since these cones are similar, height must also be 3/4 times smaller.

So since radius is squared and we also multiple the height (V = 1/3 π r² h),
the volume of smaller cone would be 3³ / 4³ = 27 / 64 times smaller

So we have 1920 * (27 / 64) = 810.

Final answer: B

Why Did the Piano Player Bang Her
Sedbober [7]

The circumference of a circle that was computed when the diameter is 3cm will be 9.426cm.

<h3>How to find the circumference?</h3>

The circumference of a circle of gotten by the formula:

C = 2πr or πd

where,

r = radius

d = diameter

Since the diameter is given as 3cm, the circumference will be:

= πd

= 3.142 × 3

= 9.426cm

In conclusion, the circumference of the circle is 9.426cm.
