The system has an infinite number of solutions, but the only solution is (a, b) = (0, 0).

The given system of equations can be solved using the substitution method. We can begin by solving the first equation,[tex]a^2 + b^2[/tex], for either a or b. Let's solve for a:

[tex]a^2 + b^2 = 0[/tex]

[tex]a^2 + b^2 = 0[/tex]

[tex]a^2 = -b^2[/tex]

[tex]a = \pm\sqrt(-b^2)[/tex]

We can substitute this expression for a into the second equation, [tex]3a^2 - 2ab - b^2 = 0[/tex], and simplify:

[tex]3(\pm\sqrt(-b^2))^2 - 2(\pm\sqrt(-b^2))b - b^2 = 0[/tex]

[tex]3b^2 - 2b^2 - b^2 = 0[/tex]

0 = 0

Since 0 = 0, this means that the system of equations has an infinite number of solutions. In other words, any values of a and b that satisfy the equation [tex]a^2 + b^2 = 0[/tex] will also satisfy the equation [tex]3a^2 - 2ab - b^2 = 0[/tex]

However, the equation [tex]a^2 + b^2 = 0[/tex] only has a single solution, which is a = b = 0. Therefore, the solution to the system of equations is (a, b) = (0, 0).

The value of sin Ф is 72/97.

We have,

Since cos Ф = -65/97 and Ф terminates in quadrant III, we know that cos Ф is negative (since cosine is negative in quadrants II and III).

We can use the Pythagorean identity to find sin Ф:

sin² Ф + cos² Ф = 1

Substituting cos Ф = -65/97, we get:

sin² Ф + (-65/97)² = 1

Simplifying, we get:

sin² Ф = 1 - (-65/97)²

Taking the square root of both sides (since sin Ф is positive in quadrant III), we get:

sin Ф = √(1 - (-65/97)²)

sin Ф = √(1 - 4225/9409)

sin Ф = √(5184/9409)

sin Ф = 72/97

Therefore,

The value of sin Ф is 72/97.

Answer:

Step-by-step explanation:

Answer: 48 cm square

Step-by-step explanation:

We can first divide this shape into two rectangles, cutting it off at the 6cm line. The rectangle below has an area of 20cm square, noted by the 10 cm base and 2 cm base thickness. For the other rectangle, we can see that the height is 9cm, but since we already have done the bottom rectangle, we can subtract 2cm away from the 9cm ad get 7 cm. So the height for the top rectangle is 7cm. Then doing the same thing for the width with 10cm and 6cm gives us 4 cm. This then gives us a total of 28cm for the top and 20cm for the bottom. This combines to get us 48 cm. THE FIGURE IS NOT TO SCALE.

y=x^2

It's a very simple version of y=ax^2+bx+c. Just in this case, a = 1, b = 0 and c = 0.

1. The location of point A  and B in complex (a + bi) form is 4 + 3i, B is -6 + 4i.

2. The modulus of point A is 5.

3. The length of AB is 10.

4. B in polar form is 2√13 × (cos(146°) + i sin(146°))

5. The product of two complex numbers in rectangular form is  -36 - 2i

6. z1/z2 in polar form is z1/z2 = 4 cis (7π/6 - π/4)

1. The location of each point A and B are as follows  Arrow A is at (4, 3) and arrow B (-6, 4). therefore the location in complex (a + bi) form is 4 + 3i, B is -6 + 4i.

2. The modulus of a complex number (a + bi) is represented as √(a² + b²) ⇒ √(4² + 3²) = √(16 + 9) = √25 = 5.

3. We can calculate the length of vector AB with √(x₂-x₁)² + (y₂-y₁)²)

AB = √((-6 - 4)² + (4 - 3)²)

AB = √((-10)² + 1)

AB = √(100 + 1)

AB = √101 ⇒ 10

4. The modulus of B, r = √((-6)² + 4²) = √(36 + 16) = √52 = 2√13

θ = 180° - arctan(|4/-6|) = 180° - arctan(2/3)

θ = 180° - 33.69° = 146.31°

5. The product of the complex number can be see as follows

(4 + 3i) × (-6 + 4i) = (4×-6 - 34) + (4×4 + 3×-6)i

= (-24 - 12) + (16 - 18)i

= -36 - 2i.

6. (7π/6 - π/4) = (14π/12 - 3π/12) = 11π/12.

11π/12 × (180/π) = 165°.

In Polar form z1/z2 = 4 cis (7π/6 - π/4)

The solution of the exponential equation [tex]5^{({\frac{-x}{16})}}= 5[/tex] in terms of logarithms, or correct to four decimal places, is x ≈ -4.4431.

An exponential function is a mathematical function in the form of [tex]f(x) = a^x[/tex], where "a" is a constant and "x" is a variable. The value of the function at a particular value of "x" is found by raising "a" to the power of "x". Exponential functions are characterized by their rapid growth or decay.

We can solve for x by taking the logarithm of both sides with base 5:

[tex]5^{(\frac{-x}{16})} = 5[/tex]

[tex]log_5(5^{(\frac{-x}{16}))} = log_5(5)[/tex]

(-x/16)log₅(5) = 1

-x/16 = 1/log₅(5)

x = -16/log₅(5)

Using a calculator, we get:

[tex]\frac{925!}{(925-3)!}= 923*924*925=788,888,100[/tex]

To determine the number of ways the first, second, and third prizes can be awarded in a contest with 925 contestants, we can use the concept of permutations.

For the first prize, there are 925 contestants eligible to win. After the first prize is awarded, there are 924 remaining contestants for the second prize. Finally, for the third prize, there are 923 remaining contestants.

The number of ways to award the prizes can be calculated as the product of the number of choices for each prize:

Number of ways = 925 * 924 * 923

Calculating this expression, we find:

Number of ways = 779,449,100

Therefore, there are 779,449,100 ways to award the first, second, and third prizes in the contest with 925 contestants.

(e)  the probability of generating a sequence with exactly one repeated digit is[tex]10 * 6 * (9^4).[/tex]

Probability is described as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

The probability of generating a sequence with no identical digits is calculated as  (10/10) * (9/10) * (8/10) * (7/10) * (6/10) * (5/10) = 15,120/1,000,000.

We start by choosing  the digit to be repeated, which can be done in 10 ways and the next thing is to choose the position of the repeated digit, and can be done in 6 ways.

We then see that remaining four positions can be filled out with any of the other 9 digits and this can also be   done in [tex]9^4[/tex] ways.

Answer:

Step-by-step explanation:

You want the formula that describes the decay of an insect population from 10000 by 9% per year, and the years it takes for the population to decline by half.

An exponential function will have the form ...

  f(t) = (initial value) · (growth factor)^t

where ...

  growth factor = 1 + growth rate

Here, the growth rate is -9% per year, so the growth factor is ...

  1 -9% = 1 -0.09 = 0.91

The population is then ...

  f(t) = 10000·0.91^t . . . . . formula for number of insects

We can solve for t when f(t) = 5000 (half the original population):

  5000 = 10000·0.91^t

  1/2 = 0.91^t . . . . . . . . . . . divide by 10,000

  ln(1/2) = t·ln(0.91) . . . . . take logarithms

  t = ln(0.5)/ln(0.91) ≈ 7.3496 ≈ 7.3 . . . . years

It would take about 7.3 years for the population to reduce to less than half its present size.

__

Additional comment

We have rounded the time period to the nearest tenth, 7.3 years. At the end of that period, the population is modeled to be about 5023, not quite "less than half." To get below half the original population would take almost 7.35 years.

Steve is correct. Steve can find the difference in temperature between 7 AM and 12 PM on Wednesday by adding the distances from 0.

By using a number line, Steve can find the difference in temperature between 7 AM and 12 PM on Wednesday by adding the distances from 0. One temperature is negative and the other is positive, but by adding their distances, he can find the difference. Kelly's method of subtracting -5.1 from the temperature at 12 PM on Wednesday is not necessarily incorrect, but it does not give the exact difference in temperature between the two times. Therefore, using Steve's method, the change in temperature would be the sum of the distance from 0 to the temperature at 7 AM (which is 2.5) and the distance from 0 to the temperature at 12 PM (which is also 2.5), resulting in a difference of 5 degrees.
