Answer:

Step-by-step explanation:

Hello, this is pretty straight forward. Let me remind you the following.

The standard equation of a parabola is

\(y=ax^2+bx+c\)

But the equation for a parabola can also be written in "vertex form":

\(y=a(x-h)^2+k\)

In this equation, the vertex of the parabola is the point (h,k) .

So, here the vertex is the point (2, -25) and the axis of symmetry is x = 2

6% is the value of people did not know how to ride bike.

Answer:

The 3.907 is approximate.

====================================

Explanation:

x = number of hours that elapse

y = f(x) = number of tokens

If we use a graphing tool like a TI84 or GeoGebra, then the approximate solution to -3(2)^(x+1) + 90 = 0 is roughly x = 3.907

At around 3.907 hours is when the number of tokens is y = 0. Therefore, this is the approximate upper limit for the domain. The lower limit is x = 0.

The domain spans from x = 0 to roughly x = 3.907, and we shorten that down to 0 ≤ x ≤ 3.907

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

Plug in x = 0 to find y = 84. This is the largest value in the range.

The smallest value is y = 0.

The range spans from y = 0 to y = 84, so we get 0 ≤ y ≤ 84

Keep in mind y is the number of tokens. A fractional amount of tokens does not make sense, so we must have y be a whole number 1,2,3,...,83,84.

The x value can be fractional because 3.907 hours for instance is valid.

Extra info:

The equation M = 8 + 8 represents the given information. Maria has 16 scarves.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's let "M" represent the number of scarves that Maria has.

According to the problem, "Maria has 8 more scarves than Lucy." We know that Lucy has 8 scarves. So, Maria has 8 more than that.

We can represent this information in an equation:

M = 8 + 8

We add 8 to Lucy's 8 scarves to get the total number of scarves that Maria has, which is 16.

So, Maria has 16 scarves.

The required Maria has 16 scarves, and the expression models the situation is given as M = 8 + L.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Let's use the variable "M" to represent the number of scarves that Maria has. Since Maria has 8 more scarves than Lucy, and Lucy has 8 scarves, we can write an equation as,

M = 8 + L

where L is the number of scarves that Lucy has. Substituting L = 8 into this equation, we get:

M = 8 + 8

Answer:

Step-by-step explanation:

i am working on the assumption that nobody does all three of them

i got 4 because including the people that do swimming and park, the total number of people that do swimming is 22.

the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.

so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

Problem 1

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

Explanation:

The given table we have is

\(\begin{array}{|c|c|c|c|c|c|c|} \cline{1-7}\text{Angle} & 0 & \pi/6 & \pi/2 & 5\pi/6 & 3\pi/2 & 2\pi\\ \cline{1-7}f(x) & 1 & 0 & -1 & 0 & 3 & 1\\ \cline{1-7}\end{array}\)

If you were to graph all those points and draw a cosine curve through them, then the function you should get is

\(y = 2\cos\left(x+\frac{\pi}{2}\right)+1\)

The B coefficient is 1, so that leads to a period of

T = 2pi/B

T = 2pi/1

T = 2pi

Problem 2

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

Explanation:

Draw out a triangle with these properties

We'll use the law of cosines to find side c

c^2 = a^2 + b^2 - 2*a*b*cos(C)

c^2 = 270^2 + 170^2 - 2*270*170*cos(100)

c^2 = 117740.902710

c = sqrt(117740.902710)

c = 343.133943

c = 343.134

=============================================

Problem 3

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

Explanation:

If you started with y = sin(x) and applied the transformations stated, then you should end up with \(y = 2\sin\left(2(x+\frac{\pi}{4})\right)\\\\\)

From here, plug in x = 0 to find the y intercept.

\(y = 2\sin\left(2(x+\frac{\pi}{4})\right)\\\\y = 2\sin\left(2(0+\frac{\pi}{4})\right)\\\\y = 2\sin\left(\frac{\pi}{2}\right)\\\\y = 2*1\\\\y = 2\\\\\)

1) The period of the given function is \(2\pi\).

2) Golfer has to originally hit the ball 343.1326 yards for it to go directly to the same position on the green.

1)The function satisfying the given table will be:

\(f(x) = 2Cos(\frac{\pi }{2} +x) +1\)

or \(f(x) = -2Sinx +1\)

The period of the function is the minimum value of the dependent variable x after which the function will repeat itself.

For example, Sin x = Sin(2π + x)

So, 2π will be the period of the function.

Suppose the period of the given function is k

So, f(x+k) = f(x)

\(-2Sin(k+x) +1 = -2Sin x+1\)

\(Sin (k+x) = Sin x\\Sin (k+x) = Sin (2\pi +x)\)

\(k+x = 2\pi +x\)

\(k =2\pi\)

So the period of the given function is \(2\pi\).

2) Consider the first hit as the side AB of a triangle, the second hit as the adjacent side to the first side i.e BC of a triangle. So, angle B will be equal to 100 degrees.

In order to originally hit the ball for it to go directly to the same position on the green we need to calculate AC

So, from the cosine rule

\(Cos B = \frac{AB^{2} +BC^{2}-AC^{2} }{2.AB.BC}\)

AB =270

BC =170

B= 100°

\(Cos 100 = \frac{270^{2} +170^{2}-AC^{2} }{2.270.170}\)

AC = 343.1326 yards

Therefore, 1) the period of the given function is \(2\pi\).

Given;

The length of side a=11.8 to the nearest tenth.

Answer:

x ≈ 10.6

y = 15

Step-by-step explanation:

The opposite angles in an inscribed quadrilateral are supplementary.

Therefore:

(4y+14) + (7y+1) = 180

=> 11y + 15 = 180

=> 11y = 165

=> y = 15

7x+1 + 105 = 180

=> 7x + 106 = 180

=> 7x = 74

=> x ≈ 10.6

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

We have,

We can simplify the given expression as follows:

(X - Y) 5 ÷ 8 - 1 ÷ 4 (X + Y)

= (5X - 5Y) ÷ 8 - 1 ÷ (4X + 4Y)

[distributing the factors]

= (5X - 5Y) /8 - 1/(4X + 4Y)

[finding a common denominator]

Answer:

-6/5

Step-by-step explanation:

The two points are (-2,2) and (3,-4). We use the slope intercept formula which is y2-y1/ x2-x1 = m. Plugging it in we get -4 - 2/ 3 + 2. This comes out to be -6/5.

Answer:

Isoceles

Step-by-step explanation:

Isoceles triangles have 2 sides that are the same length.

Answer:

A linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we want to have a slope equal to -2, then our line will be something like:

y = -2*x + b

Now, we also want this line to pass through the point (3, -4)

This means that when x = 3, we must have y = -4

Then:

-4 = -2*(3) + b

-4 = -6 + b

-4 + 6 = b

2 = b

Then our line is:

y = -2*x + 2

Now, the second part says that:

If this line  contains the points (2,8) and (5.b), find a and b.​

This is incorrectly written because this line clearly does not contain the point (2, 8), so i guess the actual problem is something like:

If this line  contains the points (a,8) and (5.b), find a and b.​

If the line contains the point (a, 8), this means that when y = 8, we must have x = a.

Then:

8 = -2*a + 2

8 - 2 = -2*a

6 = -2*a

6/-2 = -3 = a

a = -3

Similar reasoing for the other point, if the line contains the point (5, b), this means that when x = 5, we have y = b.

Then:

b = -2*5 + 2 = -10 + 2

b = -8

The expression for the area is a^2 + b^2 + 2ab

The attached image represents the missing information in the question

From the attached image, we have:

The area of the square is calculated using:

Area = c * c

Area = c^2

The area of the four triangles is:

Area = 4 * 0.5 * Base * Height

Area = 4 * 0.5 * b * a

This gives

Area = 2ab

When the areas of the square and the triangles are added, we have:

Total = c^2 + 2ab

Also, we have:

c^2 = a^2 + b^2 ---- Pythagoras theorem

So, we have:

Total = a^2 + b^2 + 2ab

Hence, the expression for the area is a^2 + b^2 + 2ab

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

Mark has marked off a certain percentage of the 12 square feet to save for a tomato plant, which means the remaining space will be used for onions.

Let's say Mark marks off x% of the space for the tomato plant. That means he will have (100-x)% of the space for onions.

The area of the space reserved for the tomato plant is:

12 square feet x (x/100) = 0.12x square feet

The area of the space available for onions is:

12 square feet - 0.12x square feet

Let's say each onion bulb needs y square feet of room to grow. Mark can plant as many onion bulbs as can fit in the remaining space, which is:
