in a rectangular triangle ABC A=90° AB=4 and AC=3. Find the BC hypotenuse using pythagorean theorem.

Alex Ar [27]

Answer:

BC=5

Step-by-step explanation:

BC^2= AB^2 + AC^2

x^2= 4^2 + 3^2

x^2= 16 +9

x^2= 25

${ \sqrt{25} }$

x= 5

Answer:

(a) 100 fishes

(b) t = 10: 483 fishes

t = 20: 999 fishes

t = 30: 1168 fishes

(c)

$P(\infty) = 1200$

Step-by-step explanation:

Given

$P(t) =\frac{d}{1+ke^-{ct}}$

$d = 1200\\k = 11\\c=0.2$

Solving (a): Fishes at t = 0

This gives:

$P(0) =\frac{1200}{1+11*e^-{0.2*0}}$

$P(0) =\frac{1200}{1+11*e^-{0}}$

$P(0) =\frac{1200}{1+11*1}$

$P(0) =\frac{1200}{1+11}$

$P(0) =\frac{1200}{12}$

$P(0) = 100$

Solving (a): Fishes at t = 10, 20, 30

$t = 10$

$P(10) =\frac{1200}{1+11*e^-{0.2*10}} =\frac{1200}{1+11*e^-{2}}\\\\P(10) =\frac{1200}{1+11*0.135}=\frac{1200}{2.485}\\\\P(10) =483$

$t = 20$

$P(20) =\frac{1200}{1+11*e^-{0.2*20}} =\frac{1200}{1+11*e^-{4}}\\\\P(20) =\frac{1200}{1+11*0.0183}=\frac{1200}{1.2013}\\\\P(20) =999$

$t = 30$

$P(30) =\frac{1200}{1+11*e^-{0.2*30}} =\frac{1200}{1+11*e^-{6}}\\\\P(30) =\frac{1200}{1+11*0.00247}=\frac{1200}{1.0273}\\\\P(30) =1168$

Solving (c): $\lim_{t \to \infty} P(t)$

In (b) above.

Notice that as t increases from 10 to 20 to 30, the values of $e^{-ct}$ decreases

This implies that:

${t \to \infty} = {e^{-ct} \to 0}$

So:

The value of P(t) for large values is:

$P(\infty) = \frac{1200}{1 + 11 * 0}$

$P(\infty) = \frac{1200}{1 + 0}$

$P(\infty) = \frac{1200}{1}$

$P(\infty) = 1200$

Find the missing side length in the image attached.

Aleks [24]

Answer:

? = 56.

Step-by-step explanation:

In the problem, the side 20 corresponds to side 32 and side 20 + 35 corresponds to side 32 + ?.

$\frac{20}{32} =\frac{20 + 35}{? + 32}$

$\frac{5}{8} =\frac{55}{? + 32}$

$\frac{1}{8}=\frac{11}{? + 32}$

? + 32 = 8 * 11

? + 32 = 88

? = 56.

Hope this helps!

Four thousand divided by 10 equal hundred divided ten

Alexeev081 [22]

I am quite confused what this problem asks about.

We are given that:

4,000 / 10 is equal to hundred / 10

I believe this problem is asking us how much in hundreds is 4,000

Therefore the answer is: 40

Such that:

<span>4,000 / 10 = 40 hundreds / 10</span>
