Answer: 50 red apples

Step-by-step explanation:

First divide 20 by 2 to know what you will multiply 5 by, so 20 divided by 2 equals 10. Now you multiply 5 by 10 to know how many red apples there are. 5 multiplied by 10 equals 50. So there are 20 tomatoes and 50 red apples.

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).

Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?

Marina86 [1]

Answer:

The inverse of $2(x - 2)^2 = 8(7 + y)$ is $y=\sqrt{(4x+28)}+2$

Step-by-step explanation:

Given equation : $2(x - 2)^2 = 8(7 + y)$

$\Rightarrow \frac{2(x-2)^2}{8}=7+y\\\Rightarrow \frac{2(x-2)^2}{8}-7=y$

Replace x with y and y with x

So, $\Rightarrow \frac{2(y-2)^2}{8}-7=x\\\Rightarrow \frac{2(y-2)^2}{8}=x+7\\\Rightarrow 2(y-2)^2=8(x+7)\\\Rightarrow (y-2)^2=4(x+7)\\\Rightarrow (y-2)=\sqrt{4(x+7)}\\\Rightarrow y=\sqrt{4(x+7)}+2\\\Rightarrow y=\sqrt{4x+28)}+2$

So, Option C is correct

Hence The inverse of $2(x - 2)^2 = 8(7 + y)$ is $y=\sqrt{(4x+28)}+2$
