Answer:

-3 ≥ x ≥ 9

Step-by-step explanation:

The domain are the x-values of every point in your graph. Since it a continuous domain, it'll be represented with ≥. Your two extremities are -3 and 9. Therefore, your domain is -3 ≥ x ≥ 9.

Write the log equation as an exponential equation

Serjik [45]

Answer:

$(z+5)^{(3x+4)} = 9$

Step-by-step explanation:

Tip: When $log_{a} b = c$ , $a^{c} =b$ is also true.

$log_{z+5} (9) = 3x+4$ | <em>Original equation</em>

$(z+5)^{(3x+4)} = 9$ | <em>Use tip</em>

A rectangular plot of land has an area 9/10 square mile.The length is 3/2miles whats the width

Georgia [21]

A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile

In the theory of learning, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to

fiasKO [112]

Step-by-step explanation:

From the statement:

M: is total to be memorized

A(t): the amount memorized.

The key issue is translate this statement as equation "rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized"

memorizing rate is $\frac{dA(t)}{dt}$ .

the amount that is left to be memorized can be expressed as the total minus the amount memorized, that is $M-A(t)$ .

So we can write

$\frac{dA(t)}{dt}=k(M-A(t))$

And that would be the differential equation for A(t).
