The form that most quickly reveals the y intercept is

The y intercept is (0, 21/2)

The y-intercept is the point where a function or a curve intersects the y-axis. In other words, it is the value of the dependent variable (y) when the independent variable (x) is equal to zero.

In the form,  f(x) = 1/2 x² - 5x + 21/2 it is easier to see that eliminating x by plugging in 0 leaves 21/2 which is the y intercept

hence we can easily say that the y intercept is (0, 21/2)

Answer:

Nice bro

lol

Step-by-step explanation:

The solution to the system is x = -6 and y = 4.

To solve the system by the addition method, we want to add the equations together in a way that will eliminate one of the variables.

Let's start by multiplying the first equation by -3 to get -3x - 9y = -18, and then add the second equation to it:

-3x - 9y = -18

+ 3x + 4y = -2

-------------

    -5y = -20

Now we can solve for y by dividing both sides by -5:

y = 4

We can substitute y=4 into one of the original equations, say x+3y=6, to solve for x:

x + 3(4) = 6

x + 12 = 6

x = -6

So the solution to the system is x = -6 and y = 4.

Thus after 12 minutes concentration of drug is 0.045.

The concentration C(t) of a certain drug in the bloodstream after t minutes is given by the formula \(c(t) = 0.05(1-e^{-0.2t} )\)

Drug concentration is amongst the most important determinants of clinical response to a drug.

Drug concentration will be seen to increase in biological samples drawn from the systemic circulation when the amount of drug absorbed exceeds the amount of drug that is distributed into the extravascular tissues and the drug that is metabolized and/or excreted during this period.

Thus after 12 minutes concentration of the drug is = C(5).

Now

C(5) = \(0.05(1-e^{-0.2t} )\)

= \(0.05(1-e^{-2.4} )\)

= 0.05(1-0.0907)

= 0.05×0.9093

= 0.045

Answer:

k = 2.8

Step-by-step explanation:

Subtract 3.9 from both sides of the equation

k + 3.9 = 6.7

k + 3.9 - 3.9 = 6.7 - 3.9

k = 3.9 - 6.7

k = 2.8

The value of  y and x intercepts are 1 and -5/2

We should know that the x-intercept is the point where the x line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis respectively

The equation of the graph is give as follows

m=(y-y₁)/(x-x₊)

Taking the points (0,1) and (5,3)

We can use them to find the slope

3-1/5-0

m=2/5

Applying this to the equation of the line to get

2/5 = y-1/x-0

2/5=y-1/x

Cross and multiply to get

2x=5y-5

Rewrite the equation and make y the subject of the relation

y=2/5x+1

When y=0 2/5x=-1

This implies that x= -5/2

Also, when x=0

y=0+1 = 1

The value of the n is 1

In a direct variation, the relationship between two variables is of the form y = kx, where k is a constant of proportionality.

To find the constant of proportionality k in this problem, we can use the fact that the given points satisfy the equation for direct variation.

(2,18) is one of the given points, so we can substitute these values into the equation y = kx and solve for k:

18 = k(2)

k = 18/2

k = 9

Now that we have found the value of k, we can use it to find n when y = 9:

9 = 9n

n = 1

Step-by-step explanation:

Let x be the rental fee for the kayak for 3 days.

Then, we can write:

x + 16 = 70

This equation represents the total amount Ronald paid, which includes the rental fee for the kayak and the cost of the guided waterfall tour.

To solve for x, we can subtract 16 from both sides of the equation:

x = 70 - 16

x = 54

The confidence interval for the proportion of millennials that care about Jobs/Economy is (0.22, 0.28).

The term confidence interval refers statistical measure used to indicate the range of estimates within which an unknown statistical parameter is likely to fall.

Here we have given that Jobs/Economy 25%, Immigration 17%, Healthcare 16%, Education 16%, Environment 12%.

And we need to find the confidence interval for the proportion of millennials that care about Jobs/Economy.

As per the formula of confidence interval,

CI = x ± Z× s/√n

CI = 25 ± 1.9600 × 0.03/ √50

CI = 25 ± 0.00832

Area = 706.8583471

Explanation:

The used law to measure the surface area of the sphere is

\(area \: = 4\pi \: {r}^{2} \)

Where (r) is the radius. The radius is half the diameter, so it will be half 13 which is equal to 7.5. By using this law:

\(4\pi \: {7.5}^{2} = 706.8583471\)

Answer:

Step-by-step explanation:

I assume that "side length" means the slant height of one of the triangular faces.

area of a triangular face = ½(base)(side length) = ½(7)(11.5) = 40.25 in

lateral area = all four triangles = 161 in²

base area = 7² = 49 in²

total surface area = lateral area + base area = 161+49 = 210 in²

The area of the pyramid is  1.4625 ft²

If the base of the pyramid is in the shape of a square (base with 4 sides), then it is called a square pyramid. As the square has 4 sides, then the square pyramid has the following properties: No. of Faces: (4+1) = 5 No.of Vertices: (4+1)= 5 No. of Edges: 2(4) = 8

Given here: The height is 11, the base is 7 in, and the side length is 11.5 inches of a pyramid.

The surface area of a square pyramid is the sum of the areas of its square base and four triangular faces:

SA = BA + (4 × FA)

     =\(a^2+a\sqrt{a^2+4h^2}\)

Where a= base length and height = h

Thus inputting the values we get

SA= 7²+7\(\sqrt{7^2+4.11^2}\)

   =49+7√533

    =210.60 in²

Thus in ft.² we have 1.4625 ft²

Answer:

The answer is the third table

Step-by-step explanation:

Looking at the first table, that is a many-to-one function. We can say it's many-to-one because when looking at the inputs (x), for both 8 and 11, the output is the same. Remember, In a function, x can have only one output. Therefore, this satisfies that requirement, but it is not a one-to-one function.

In the second table, we have one-to-many. When looking at the inputs (x), there are the numbers 2, 8, and 8. Since the number 8 repeats and has different outputs 7 and 15, this makes it a one-to-many. Additionally, it is not a function, because it should not have two different outputs.

The third table is a one-to-one function. This is because the inputs 2,8 and 11 each have one output. Hence, it is also a function, and this is the correct answer.

Step-by-step explanation:

Let h(x) = y

The exponentail function is of the form :

\(y = ab^x\)

We have :

\(y_{_1} = ab^{x_{_1}}\\y_{_2} = ab^{x_{_2}}\\\\\implies \frac{y_{_1}}{y_{_2}} = \frac{ab^{x_{1}}}{ab^{x_{2}}} \\\\\implies \frac{y_{_1}}{y_{_2}} = \frac{b^{x_{1}}}{b^{x_{2}}} \\\\\implies \frac{y_{_1}}{y_{_2}} = b^{(x_1-x_2)}\)

Given points : (4, 9) and (5, 34.2)

We have:

\(\frac{34.2}{9} = b^{(5-4)}\\\\\implies 3.8 = b\)

Writing the equation with x, y and b:

\(y = ab^x\\\\\implies 9 = a(3.8^4)\\\\a = \frac{9}{3.8^4} \\\\a = 0.043\)

a = 0.043

b = 3.8

When x = 6, y will be:

\(y = (0.043)(3.8^6)\\\\y = 128.47\)

This is not the y value in the question y = 59.4
