Answer:

Therefore, we conclude that is needed 72000 salmon eggs  to produce 18 adult salmon.

Step-by-step explanation:

We know that scientists study ways to increase the population of wild salmon. We know that for every 8,000 eggs, only 2 adults may survive.

We calculate how many salmon eggs may be needed to produce 18 adult salmon.  

Therefore, we get:

2\cdot 9=18\\\\\\9\cdot 8000=72000

Therefore, we conclude that is needed 72000 salmon eggs  to produce 18 adult salmon.

Which of the following is equivalent to 2 ln e^ln 5x = 2 ln 15?
neonofarm [45]

Answer:

x  = 3

Step-by-step explanation:

Given in the question an equation,

2lne^{ln5x}=2ln15

Step 1

e^{lnx}=x

so,

2ln(5x)=2ln15

Step 2

cancel 2 on both sides of the equation

ln{5x}=ln15

Step 3

ln{5x}-ln15=0

ln\frac{5x}{15}=0

Step 4

ln\frac{x}{3}=0

Step 5

e^{ln\frac{x}{3}}=e^{0}

Step 6

x/3 = 1

x = 3(1)

x = 3

The function, f(x) = –2x2 + x + 5, is in standard form. The quadratic equation is 0 = –2x2 + x + 5, where a = –2, b = 1, and c =
avanturin [10]
Given:

The function, f(x) = -2x^2 + x + 5

Quadratic equation: 0 = -2x^2 + x +5
where a = -2
            b = 1
            c = 5

The discriminate b^2 - 4ac = 41

To solve for the zeros of the quadratic function, use this formula:

x = ( -b +-√ (b^2 - 4ac) ) / 2a

x = ( 1 + √41 ) / 4  or 1.85
x = ( 1 - √41 ) / 4  or -1.35

Therefore, the zeros of the quadratic equation are 1.85 and -1.35.

Two equations are given below:
brilliants [131]
A − 3b = 16
a = b − 2

b - 2 - 3b = 16
2b = - 18
b = - 9

a = - 9 - 2
a = - 11

(-11,-9)
