The initial expression is:

$-10+\frac{r}{5}=1$

So we can solve for r so:

$\begin{gathered} \frac{r}{5}=1+10 \\ r=11\cdot5 \\ r=55 \end{gathered}$

Let p denote the population of the United States (in millions) in the year

Fofino [41]

Answer:

dp/dt = 10⁻⁵p(2225 − 4.2381p)

Step-by-step explanation:

Since the function is

0 = ln p + 45.8177 − ln (2225 − 4.2381p) − 0.02225t

Differentiating the function implicitly with respect to time, we have

d0/dt = d[ln p + 45.8177 − ln (2225 − 4.2381p) − 0.02225t]/dt

d0/dt = d[ln p]/dt + d[45.8177]/dt − d[ln (2225 − 4.2381p)]/dt − d[0.02225t]/dt

0 = (1/p)dp/dt + 0 − (1/(2225 − 4.2381p)) × -4.2381 dp/dt − 0.02225

0 = (1/p)dp/dt + 4.2381 dp/dt/(2225 − 4.2381p) − 0.02225

-(1/p)dp/dt - 4.2381 dp/dt/(2225 − 4.2381p) = − 0.02225

(1/p)dp/dt + 4.2381 dp/dt/(2225 − 4.2381p) = 0.02225

Factorizing out dp/dt from the left hand side, we have

[(1/p) + 4.2381/(2225 − 4.2381p)]dp/dt = 0.02225

taking L.C.M of the left-hand-side and simplifying, we have

[((2225 − 4.2381p + 4.2381p)/p(2225 − 4.2381p)]dp/dt = 0.02225

[2225/p(2225 − 4.2381p)]dp/dt = 0.02225

dividing both sides by2225, we have

[1/p(2225 − 4.2381p)]dp/dt = 0.02225/2225

[1/p(2225 − 4.2381p)]dp/dt = 0.00001

[1/p(2225 − 4.2381p)]dp/dt = 10⁻⁵

multiplying both sides by p(2225 − 4.2381p), we have

p(2225 − 4.2381p)[1/p(2225 − 4.2381p)]dp/dt = 10⁻⁵p(2225 − 4.2381p)

So, dp/dt = 10⁻⁵p(2225 − 4.2381p)

Find the range of f(-5)=-2|x-5|+8 please with explination.

Nesterboy [21]

Answer:

Domain: set of possible input values (x-values)

Range: set of output values (y-values)

The range for the function $f(x)=-2|x-5|+8$ is:

$f(x)\leq 8$

(5, 8) is the vertex of the line

Because |x - 5| is absolute (so always positive) and it is multiplied by -2,

-2|x - 5| will always be negative unless x = 5 (when it will be zero). Therefore, the max y-value is 8.

However, your question actually asked what the function is when x = -5:

$f(-5)=-2|x-5|+8\\\\= -2|-5-5|+8\\\\= -12$

What is a31 of the<br> arithmetic sequence for<br> which a5 = 12.4 and<br> ag = : 22.4?

MrMuchimi

The value of a₃₁ of the arithmetic sequence exists 77.4.

<h3>How to find the value of a₃₁ of the arithmetic sequence?</h3>

Given: a₅ = 12.4 and a₉ = : 22.4

For the arithmetic sequence a₁, a₂, a₃, ..., the n-th term exists

where d = common difference

a₅ = 12.4,

a₁ + 4d = 12.4 .........(1)

Because a₉ = 22.4,

a₁ + 8d = 22.4 .........(2)

Subtract (1) from (2), we get

a₁ + 8d - (a₁ + 4d) = 22.4 - 12.4

4d = 10

Dividing throughout by 4, we get

d = 2.5

From (1), we get

a₁ = 12.4 - 4 $*$ 2.5 = 2.4

a₃₁ = 2.4 + 30 $*$ 2.5 = 77.4

Therefore, the correct answer is a₃₁ = 77.4
