solve using the quadratic equationX^2 -4x -3 =0

Answers

Answer:

[tex]x = 2[/tex] ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

Lets see the quadratic equation :

x = -b ± [tex]\sqrt{b^2 - 4ac}[/tex] / 2a

So now we have our quadratic :

[tex]x^2 - 4x - 3 =0[/tex]

a = ?^2 (Exponent)

b = ?x (Variable)

c = ? (Constant)

So replace every variable in the quadratic equation with the ones in the quadratic formula.

x = -(-4) ± (-4)^2 - 4(1)(-3) / 2(1)

(Imagine (-4)^2 - 4(1)(-3) in a square root)

x = 4 ± [tex]\sqrt{16 - - 12}[/tex] / 2

x = 4 ± [tex]\sqrt{28}[/tex] / 2

Of course 28 isn't available for a square root property, so lets break it up :

x = 4 ± [tex]2\sqrt{7}[/tex] / 2

Simplify the radical :

[tex]x = 2[/tex] ± [tex]\sqrt{7}[/tex]

A fisherman illegally drops some fish into a pond, and they quickly propagate (reproduce). The population
growth of the new specifies is modeled by P(x) =6(b)^x where x is the time in weeks following the moment
he dropped the fish into the pond and b is a positive unknown base. Suppose that b is 3. Graph this
relationship. How long does it take for there to be at least 100 fish in the pond?

Answers

Answer:

C. About 6 days

Step-by-step explanation:

Here the function that shows the population of fish after x weeks,

Where b is any unknown,

If b = 3,

Then, the function is,

Which is a exponentially increasing function,

That having y-intercept = (0,1)

And, horizontal asymptote,

y = 0

End behavior of the function:

As ,

Thus, by the above information we can graph the given relation.

Now, For at least 100 fish in the pound,

By taking log on both sides,

Thus, after 0.8567 weeks (approx) the fish on the pound will be at least 100.

1 week = 7 days,

0.8567 weeks = 5.9969 days ≈ 6 days

Hence, after 6 days (approx) the fish on the pound will be at least 100.

Question
Solve the real-world situation by using the substitution method.
Jen is riding her bicycle on a trail at the rate of 0.33 kilometer per minute. Michelle is 8
kilometers behind Jen when she starts traveling on the same trail at a rate of 0.43 kilometer
per minute. Let d represent the distance in kilometers the bicyclists are from the start of
the trail and t represent the time in minutes.
The system of equations
d = 0.33t + 8
d = 0.43t
can be used to represent this situation.
р.
How many minutes will it take Michelle to catch up to Jen? How far will they be from the
start of the trail? Use the substitution method to solve this real-world application.
Michelle will catch up to Jen in
of the trail.
minutes and they will be
km from the start

Answers

9514 1404 393

Answer:

80 minutes34.4 km

Step-by-step explanation:

Use the second equation to substitute for d in the first equation.

0.43t = 0.33t +8

Subtract 0.33t from both sides

0.10t = 8

Multiply by 10

t = 80 . . . . . . Michelle will catch Jen in 80 minutes

The distance traveled will be ...

d = 0.43t = 0.43×80 = 34.4 . . . . km

The girls will have traveled 34.4 km when they meet.

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

if eight times a number is increased by 3 the result is 19 more than six times this digit. find the number

Answers

Answer:

Step-by-step explanation:

Even though we don't know the number yet, let's name this number "n".

8n + 3 = 6n + 19

8n + 3 - 6n = 6n + 19 - 6n

2n + 3 = 19

2n = 16

n = 16/2

n = 8

Our number is 8.
