Answer:

[tex]\large\boxed{\text{Factored Form:}\ f(x)+-(x-1)(x-5)}\\\boxed{\text{Vertex Form:}\ f(x)=-(x-3)^2+4}\\\boxed{\text{Standard Form:}\ f(x)=-x^2+6x-5}[/tex]

Step-by-step explanation:

(look at the picture)

Factored form:

[tex]f(x)=a(x-x_1)(x-x_2)[/tex]

x₁, x₂ - zeros

Vertex form:

[tex]f(x)=a(x-h)^2+k[/tex]

(h, k) - vertex

Standard form:

[tex]f(x)=ax^2+bx+c[/tex]

If from the vertex we go 1 unit down (up) and 1 unit left (right) and we get the point on the parabola, then a = 1.

The parabola is open down, therefore a < 0 → a = -1.

The zeros are [tex]x_1=1[/tex] and [tex]x_2=5[/tex]. Therefore the Factored Form is:

[tex]f(x)=-(x-1)(x-5)[/tex]

The vertex is V(3, 4). Therefore the vertex form is:

[tex]f(x)=-(x-3)^2+4[/tex]

Convert it to a standard form using (a - b)² = a² - 2ab + b²

[tex]f(x)=-(x^2-2(x)(3)+3^2)+4=-x^2+6x-9+4=-x^2+6x-5[/tex]

Answer:

-12

Step-by-step explanation:

y = 4x^2 + 8x - 8

Put brackets around the first 2 terms and pull out the common factor

y = (4x^2 + 8x) - 8

y = 4(x^2 + 2x) - 8

Take 1/2 of the linear term (2x) and square it. Put the square inside the brackets.

y = 4(x^2 + 2x + (2/2)^2 ) - 8

y = 4(x^2 + 2x + 1) - 8

You have added 4*1 inside the brackets. You must subtract that amount outside the brackets.

y = 4(x^2 +2x + 1) - 8 - 4

Notice that the trinomial inside the brackets is a perfect square. Combine the terms outside the brackets.

y = 4(x + 1)^2 - 12    

You have completed the square and you are finished.

The vertex is (-1, - 12)

The y value is - 12.

Just to confirm this, I have included the graph.

Answer:

c. the zeros, -24 and 24, can be found when 0= (x+24)(x-24).

Step-by-step explanation:

The given function is

[tex]g(x)=x^2-576[/tex]

When we equate the function to zero, we obtai;

[tex]x^2-576=0[/tex]

Use difference of two squares:

[tex]x^2-24^2=0[/tex]

[tex](x-24)(x+24)=0[/tex]

Use the zero product property to obtain;

[tex]x-24=0,\:and\:x+24=0[/tex]

This implies that;

[tex]x=24,\:and\:x=-24[/tex]

The correct choice is C

Answer:

The zeros, -24 and 24, can be found when 0= (x+24)(x-24).

Step-by-step explanation:

Answer:

x = 4, y = 1

Step-by-step explanation:

Given the 2 equations

4x + y = 17 → (1)

2x + y = 9 → (2)

Subtract (1) from (2) term by term

(4x - 2x) + (y - y) = (17 - 9)

2x = 8 ( divide both sides by 2 )

x = 4

Substitute x = 4 into (1) and solve for y

4(4) + y = 17

16 + y = 17 ( subtract 16 from both sides )

y = 1

Answer:

B

Step-by-step explanation:

A geometric series will only converge if the common ratio r meets the requirement

- 1 < r < 1

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]

where a is the first term and r the common ratio

All terms inside the summation are of this form

The only one with - 1 < r < 1 is B where r = [tex]\frac{3}{4}[/tex] = 0.75

The series with the common ratio 2/3 and 3/4 converge. That is option A. [tex]sum n = 1 to ∞ 1/6 * (4)^(n-1)[/tex] and option B. [tex]sum n = 1 to ∞ 5 * (3/4)^(n-1)[/tex]

To determine whether a geometric series converges or diverges, we need to examine the common ratio (r) of the series. A geometric series converges if the absolute value of the common ratio is less than 1 (|r| < 1). It diverges if the absolute value of the common ratio is greater than or equal to 1 (|r| ≥ 1).

Let's analyze each series:

1. [tex]sum n = 1 to ∞ 1/6 * (4)^(n-1)[/tex]

The common ratio in this series is 4/6, which simplifies to 2/3. Since |2/3| < 1, this series converges.

2. [tex]sum n = 1 to ∞ 5 * (3/4)^(n-1)[/tex]

The common ratio in this series is 3/4. Again, |3/4| < 1, so this series also converges.

3. [tex]sum n = 1 to ∞ 3 * (7/5)^(n-1)[/tex]

The common ratio in this series is 7/5. However, |7/5| > 1, which means the series diverges.

4. [tex]sum n = 1 to ∞ 1/9 * (1)^(n-1)[/tex]

The common ratio in this series is 1. Since |1| ≥ 1, this series also diverges.

In summary:

- The series with the common ratio 2/3 and 3/4 converge.

- The series with the common ratio 7/5 and 1 diverge.

The reason behind this is that when the absolute value of the common ratio is less than 1, each subsequent term in the series becomes smaller and smaller. As a result, the sum of the series approaches a finite value. Conversely, if the absolute value of the common ratio is greater than or equal to 1, the terms in the series do not decrease enough, causing the sum to increase without bound, leading to divergence.

Answer:

x < -4 or (-∞,-4)

Step-by-step explanation:

to solve 8x < -32, we treat the inequality symbol as an = sign and solve it like we would any other equation: get x alone

8x < -32 < divide both sides by 8 to isolate x

8x/8 = x

-32/8 = -4

x < -4 is our solution

in interval notation this can be written as (-∞, -4)

1062.32. that's how much he will have after 4 years

Colin will have £1,062.32 after 4 years.

Simple interest is the type of interest in which the accumulated interest amount is not taken into consideration while adding the interest.

It is given by:

SI = P*r*T/100

The amount that Colin invests is given as £980.

The rate of interest is given as 2.1%.

The amount is deposited for 4 years.

The total amount in the bank after 4 years can be given by:

Amount = P + P*r*T/100

= P(1 + 2.1*4/100)

= 980(1 + 0.084)

= 980 * 1.084

= £1,062.32

The total amount that Colin would have after 4 years is found. The Amount that Colin would have is equal to £1,062.32.

Therefore, we have found that Colin will have £1,062.32 after 4 years.

(from my own work it would be ,I'm not saying its right or wrong though)

The probability that Terry randomly chooses an outfit with black pants and a yellow shirt is 1 out of 12, calculated by dividing the number of favorable outcomes (1) by the total possible outcomes (12).

The question revolves around basic probability. Terry has three pairs of pants and four shirts, meaning there are a total of 3 x 4 = 12 possible outfits. Since only one outfit consists of black pants and a yellow shirt, the probability of selecting this combination is therefore 1 out of 12.

The formula used to calculate this probability is the number of favorable outcomes divided by the total number of possible outcomes. In this case, the favorable outcome (black pants with a yellow shirt) is just one, and the total number of possible outfits is twelve.

Answer:

46

Step-by-step explanation:

I went to google.

Search up 20% of 230,

got 46 lol

If there is an aquarium containing 230 fish, 20% are angelfish, then there are 46 angelfish in the aquarium.

To find the number of angelfish in the aquarium, we first need to calculate 20% of 230, as the given percentage represents the proportion of angelfish in the total fish population.

Calculate 20% of 230

To find 20% of a number, we multiply the number by 0.20 (which is the decimal equivalent of 20%).

20% of 230 = 0.20 * 230

= 46

Determine the number of angelfish

Now that we know that there are 46 angelfish in the aquarium, we have successfully answered the question.

2.4cm is the tangent of A

Final answer:

The tangent of angle A, with angle A opposite side X in a right triangle where X = 10 cm and Y = 24 cm, is approximately 0.4167.

Explanation:

If we have a triangle with sides X = 10 cm, Y = 24 cm, and Z = 26 cm, we can use the tangent function to determine the tangent of angle A, assuming that angle A is opposite the side X. Using the fact that the y-axis passing through the third charge bisects the 24-cm line, we create two right triangles of sides 5, 12, and 13 cm, indicating that the triangle in question is in fact a right triangle, with the two smaller sides being X and Y, and the hypotenuse being Z.

Using the definition of tangent, which in a right triangle is the ratio between the side opposite to the angle and the side adjacent to the angle, the tangent of angle A would be tan(A) = opposite / adjacent. In this triangle, that would mean:

tan(A) = X / Y = 10 cm / 24 cm

Calculating this gives us:

tan(A) ≈ 0.4167

Therefore, the tangent of angle A is approximately 0.4167.

Answer:

The vertex is the point (3, 6)

Step-by-step explanation:

For a quadratic function [tex]ax ^ 2 + bx + c[/tex] its vertex form is:

[tex]y = a (x-h) ^ 2 + k[/tex]

Where

a is the main coefficient

h is the x coordinate of the vertex

k is the cordage y vertice

Therefore, for a function in this way the vertex will always be the point (h, k)

Notice that for the function

[tex]f (x) = -4 (x-3) ^ 2 + 6\\\\a = -4\\\\h = 3\\\\k = 6[/tex]

Then the vertex is the point (3, 6)

Answer:

(3, 6)

Step-by-step explanation:

Since the question is in y = 1(x-h)^2 +k form and you just put the opposite sign for h making it from 3 to -3.

So far we got x as 3.

and for Y you have k which is 6 so you final answer would be (3,6)

[tex]f(x)=3x^3+x^2+3x+1[/tex]

Step-by-step explanation:

If a real number [tex]-\frac{1}{3}[/tex] is a zero of polynomial function, then

[tex]x-\left(-\dfrac{1}{3}\right)=x+\dfrac{1}{3}[/tex]

If a complex number [tex]-i[/tex] is a xero of the polynomial function, then the complex number [tex]i[/tex] is also a zero of this function and

[tex]x-(-i)=x+i\ \text{ and }\ x-i[/tex]

are two factors of this function.

So, the function of least degree is

[tex]f(x)=\left(x+\dfrac{1}{3}\right)(x+i)(x-i)=\left(x+\dfrac{1}{3}\right)(x^2-i^2)=\\ \\ =\left(x+\dfrac{1}{3}\right)(x^2+1)=\dfrac{1}{3}(3x+1)(x^2+1)=\dfrac{1}{3}(3x^3+x^2+3x+1)[/tex]

The sum of temperatures over five days in St. Paul, Minnesota would be calculated by adding the individual temperatures of each day together. If any temperatures are negative, it would decrease the total sum.

To find the sum of the various temperatures over the five days in St. Paul, Minnesota, you need to know the specific temperatures for each day. Assuming we have those temperatures, let's say they are 20°C, 22°C, 19°C, 21°C, and 23°C. You simply add these temperatures together: 20 + 22 + 19 + 21 + 23. The total would be 105°C for the five days. This is a basic mathematical operation, summarizing data by adding them together. Note: If any of the temperatures were negative (like -5°C), this would decrease the sum because you would be essentially subtracting that value.

Answer:

B

Step-by-step explanation:

Given

5x² + 40x - 100

To find the zeros equate to zero, that is

5x² + 40x - 100 = 0 ( divide all terms by 5 )

x² + 8x - 20 = 0

To factor the quadratic

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (+ 8)

The factors are + 10 and - 2, since

10 × - 2 = - 20 and 10 - 2 = + 8, thus

(x + 10)(x - 2) = 0

Equate each factor to zero and solve for x

x + 10 = 0 ⇒ x = - 10

x - 2 = 0 ⇒ x = 2

Zeros are x = - 10 and x = 2 → B
