Answer:  26.67%

Step-by-step explanation:

32 touchdowns divided by 12 interceptions

32/12 = 26.66666%

26.66666 rounds up to 26.67%

Final answer:

The simplified ratio of touchdowns to interceptions that Max threw is 8:3, found by dividing both the number of touchdowns (32) and interceptions (12) by their greatest common divisor, which is 4.

Explanation:

To find the most simplified form of the ratio of touchdowns to interceptions that Max threw, we divide the number of touchdowns by the number of interceptions. Max threw 32 touchdowns and 12 interceptions. To simplify this ratio, we need to find the greatest common divisor (GCD) that both numbers share. In this case, the GCD of 32 and 12 is 4.

Dividing both numbers by the GCD, we get: 32 ÷ 4 = 8 and 12 ÷ 4 = 3. Therefore, the simplified ratio of touchdowns to interceptions is 8:3.

In 2036 there will be a population of 32309 rabbits.

We can calculate the exponential decay using the following function:

[tex]P(t)=StartAmount*(1-\frac{percent}{100})^{t}[/tex]

Where,

Start Amount, is the starting value or amount.

Percent, is the decay rate.

t, is the time elapsed.

We are given:

[tex]StartAmount=144,000\\x=7.2(percent)\\t=2036-2016=20years[/tex]

Now, substituting it into the equation, we have:

[tex]P(t)=StartAmount(1-\frac{percent}{100})^{t}[/tex]

[tex]P(t)=144000*(1-\frac{7.2}{100})^{20}[/tex]

[tex]P(t)=144000*(1-0.072)^{20}[/tex]

[tex]P(t)=144000*(0.928)^{20}[/tex]

[tex]P(t)=144000*(0.928)^{20}[/tex]

[tex]P(t)=144000*0.861=32308.888=32309[/tex]

P(B) be the event that black marble is drawn

P(A) = 1/4

P(B) = 1/2

Both events A and B are independent as the first marble is put back before drawing the second marble. So the probabilities of two independent events are multiplied.

Answer: The answer would be D. 64

Step-by-step explanation: Understanding that the question noted that the second rectangle was dilated from PQRS, which has a perimeter of 16. With the coordinates of point P for the first rectangle being (2,0.5) whilst the second rectangle has point P at (8,2). To figure out the perimeter, divide point P from the second rectangle with point P from the first. The result would be 4. Thus, the scale factor is 4, which you then multiply the perimeter of PQRS by, which was 16. 16 times 4 equals 64.

[tex]\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ \cline{1-1} A=452.16 \end{cases}\implies 452.16=\pi r^2\implies \cfrac{452.16}{\pi }=r^2 \\\\\\ \stackrel{\pi =3.14}{\cfrac{452.16}{3.14 }}=r^2\implies 144=r^2\implies \sqrt{144}=r\implies 12=r[/tex]

low and behold, the radius of the 1st one is 12 as well, so both cylinders have the same radius.  Let's recall the volume of a cylinder is V = πr²h.

The solution set is { (3, 4), (5 , 0) }.

Step-by-step explanation:

x^2 + y^2= 25

2x   +   y =  10

We use substitution:

From the second equation y = 10 - 2x.

Substituting for y in the first equation:

x^2 + (10 -2x)^2 = 25

x^2 + 100 - 40x + 4x^2 - 25 = 0

5x^2 - 40x  + 75 = 0

Divide through by 5:

x^2 - 8x + 15 = 0

(x - 3)(x - 5) = 0

x = 3, 5.

when x = 3 , y = 10 - 2(3) = 4.

when x = 5, y = 10 - 2(5) = 0.

Answer:

The perimeter is 24 sq inches.

Step-by-step explanation:

In order to find perimeter, you must add together all the sides. So the equation would be (LxW)2 , or just Length plus Length plus Width plus Width. Therefore, it is either (7x5)2 or 7 + 7 + 5 + 5 which both equal 24 sq inches. Hope this helps!

The perimeter of a rectangle with an area of 35 square inches, length of 7 inches, and width of 5 inches is calculated using the formula P = 2l + 2w, resulting in a perimeter of 24 inches.

To calculate the perimeter of a rectangle when given the area and the dimensions, we use the formula P = 2l + 2w, where 'P' represents the perimeter, 'l' is the length, and 'w' is the width of the rectangle. If we know the length is 7 inches and the width is 5 inches, we can plug these values into the formula to find the perimeter:

P = 2(7) + 2(5) = 14 + 10 = 24 inches.

Therefore, the perimeter of the rectangle with an area of 35 square inches, length of 7 inches, and width of 5 inches is 24 inches.

Answer:

The length is 24, width is 6

Step-by-step explanation:

Since we know the length and width cannot both be 12 (to make 144), other factors of 12 can be tested to be a product of 144. Half of 12 is 6, and 24 * 6 = 144. If we add up 12 + 12 + 6 + 6, we get 60, or the given perimeter.

Hope I helped and please give me brainliest!

The length and width of the rectangle, set up and solve a system of equations based on the given area and perimeter. By factoring the quadratic equation obtained from the area and perimeter formulas, it is determined that the rectangle's width is 12 inches and its length is 18 inches.

The length and width of a rectangle with an area of 144 square inches and a perimeter of 60 inches, we can set up a system of equations using the formulas for area and perimeter of a rectangle, which are Area = length  imes width and Perimeter = 2  imes (length + width), respectively. Let the length be represented by 'l' and the width by 'w'.

Step 1: Set up the equations

Area = l  times w = 144
Perimeter = 2l + 2w = 60

Step 2: Solve the system of equations

First, simplify the perimeter equation to get l + w = 30. Then, express l in terms of w: l = 30 - w. Now substitute l in the area equation: (30 - w)w = 144.

Step 3: Solve the quadratic equation

Expand the equation: 30w - w² = 144.
Rearrange to form: w²- 30w + 144 = 0.
Factoring the quadratic equation gives: (w - 12)(w - 18) = 0.

Step 4: Find w and l

Setting each factor equal to zero gives us two possible widths: w = 12 or w = 18. If w = 12, then l = 30 - w = 18. If w = 18, then l = 30 - w = 12. Since both options give us the same pair of numbers, and a rectangle's sides can be switched without changing its shape, the rectangle's width is 12 inches and its length is 18 inches, or vice versa.

we can simplify it to this:

[tex]y = - 2 {x}^{2} - 12x - 16 [/tex]

so we know it , the intercept in a standard equation of a parabola is C:

[tex]a {x}^{2} + bx + c[/tex]

so the intercept is (-16) and for the vertex use:

x=-b/2a

[tex]x = \frac{12}{ - 4} = - 3 [/tex]

so now put it in the equation and get the y of vertex:

y=-18+36-16=2 ==>vertex(-3,2)

Final answer:

The vertex of the function y=-2(x+3)²+2 is (-3, 2). The y-intercept is at (0, -16).

Explanation:

To identify the vertex and the y-intercept of the graph of the function y=-2(x+3)2 +2, we need to understand the structure of a quadratic function in vertex form, which is y=a(x-h)2+k, where (h, k) is the vertex of the parabola and a determines the direction and width of the parabola.

For the given function, the vertex can be found by looking at the values inside the parentheses and the constant term outside. In this case, the vertex is at x = -3 and y = 2, so the vertex is (-3, 2). The y-intercept occurs where x = 0. Substituting x = 0 into the function, we get y = -2(0+3)2+2 = -2(9)+2 = -18+2 = -16. Therefore, the y-intercept is at (0, -16).

TLDR: The answer is -2.

What you have here is a function with a point on the graph. It is understood that “x” represents the input and “y” represents the output, so we’re looking for the right “x” that will give y = 1/100.

To start, we can substitute the y-value into the function like this:

y = 10^x

1/100 = 10^x

From here, we can take two different pathways; one requires conceptual knowledge while the other relies on the knowledge of logarithms.

Conceptual

For the conceptual, we know that 100 = 10^2, so 1/100 is the same as 1/10^2. We also know that the inverse of a fraction is the same as the number to the negative of its power (for example, 1/2 is equal to 2^-1), so we know that 1/10^2 is the same as 10^-2. So far, we have learned that:

1/100 = 10^x

1/10^2 = 10^x

10^-2 = 10^x

So, to satisfy this, “x” must equal -2.

Logarithms

For logarithms, we can use powers and math to actually calculate the value of “x”. We know that:

1/100 = 10^x

To solve this, we need “x” to be by itself on one side of the equation. To do this, we can perform the inverse function of an exponent, which is a logarithm. In this case, the base of 10^x is 10, so we need a “base 10” logarithm to solve this function. Apply this function to both sides and simplify:

1/100 = 10^x

log10(1/100) = log10(10^x)

log10(1/100) = x

The log10 function is the inverse of 10^x, so they cancel out to leave “x”. Plug log10(1/100) into a calculator, and you find that x = -2.

Step-by-step explanation:

Answer:

Dividing two binomials will not always result in a polynomial. For instance, divide (x+2) over (x+3) and we won't get a polynomial. The result is known to be a rational expression but not a polynomial. So that's why division is not closed for polynomials.

Answer:

see explanation

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

(x - 4)(x + 2) = 0

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 2 = 0 ⇒ x = - 2

x- intercepts are x = - 2 and x = 4

The vertex lies on the axis of symmetry which is located at the midpoint of the x- intercepts, thus

[tex]x_{vertex}[/tex] = [tex]\frac{-2+4}{2}[/tex] = 1

Substitute x = 1 into the equation for corresponding value of y

y = (1 - 4)(1 + 2) = - 3 × 3 = - 9

vertex = (1, - 9)

The x-intercept of the line will be  x = 4 and x = -2 and Vertex = (1, - 9).

The x-intercepts are the points where the graph intersects the x-axis. The vertex is the point that defines the minimum or maximum of a parabola.

We have,

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

Now,

So, to get the x-intercept,

Put y = 0,

i.e.

0 = (x - 4) (x + 2)

NOw,

x - 4 = 0

⇒ x = 4,

And,

x + 2 = 0

⇒ x = -2

So,

x-intercepts are x = 4 and x = -2.

Now,

To get the vertex ,

For vertex,

The vertex lies on the axis of symmetry which is located at the midpoint of the x- intercepts, thus

Vertex for x [tex]=\frac{-2+4}{2}=1[/tex]

Now,

Substitute x = 1 into the equation,

i.e.

y = (1 - 4)(1 + 2)

= - 3 × 3 = - 9

So,

Vertex = (1, - 9)

Hence, we can say that the x-intercept of the line will be  x = 4 and x = -2 and Vertex = (1, - 9)
