[tex]\large\boxed{y=2(x-8)^2-72}\\\boxed{minimum\ is\ -72\ for\ x=8}[/tex]

Step-by-step explanation:

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

It's the vertex form of a quadratic equation of [tex]y=ax^2+bx+c[/tex]

The vertex is at (h, k).

k is minimum or maximum for value of h.

[tex]h=\dfrac{-b}{2a}[/tex]

k - its value of y for x = h.

We have

[tex]y=2x^2-32x+56\\\\a=2,\ b=-32,\ c=56[/tex]

[tex]h=\dfrac{-(-32)}{2(2)}=\dfrac{32}{4}=8[/tex]

The dimensions of the rectangle are 24x and 90y.

The area of a rectangle is represented by the expression 24x6y15. To determine the dimensions of the rectangle, we need to factorize the expression. Factoring out the common factors, we have:

24x6y15 = 2 × 2 × 2 × 3 × x × (2 × 3) × y × (5 × 3)

From this, we can see that the dimensions of the rectangle are:

Length = 2 × 2 × 2 × x × 3 = 24x

Width = 2 × y × 3 × (5 × 3) = 90y

Answer:

=135.53°

Step-by-step explanation:

The bearing that the captain should turn is the angle difference between the two islands from the position of the ship.

Let C be the position of the ship, then

AB is c=160

AC is b=220

BC is a=200

We use the cosine rule as follows:

c²=a²+b²-2ab Cos C

160²=200²+220²-2×200×220 Cos C

25600=88400-88000Cos C

88000 Cos C=88400-25600

88000Cos C=62800

Divide both sides by 88000.

Cos C=62800/88000

=0.7136

C=44.47°

He should turn (180°-44.47°)=135.53°

Answer:

X=-16/3 or 5.33

Step-by-step explanation:

The formula is y=mx+c

Substitute in values for gradient

6=-4×3+c

C=18

Y=3x+18

Substitute to find x

2=3x+18

-16=3x

X=-16/3

The slope of a line is the change in the y values over the corresponding x values.

The value of x, that makes the points a linear function is -16/3

Given that:

[tex]m = 3[/tex]

[tex](x_1,y_1) = (x,2)[/tex]

[tex](x_2,y_2) = (-4,6)[/tex]

The slope (m) of a line is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]3 = \frac{6-2}{-4-x}[/tex]

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

Cross multiply

[tex]3 \times (-4 -x) = 4[/tex]

Divide by 3

[tex]-4 -x = \frac 43[/tex]

Add 4 to both sides

[tex]-x = \frac 43 + 4[/tex]

Take LCM

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

[tex]-x = \frac{16}3[/tex]

Divide by -1

[tex]x =-\frac{16}3[/tex]

Hence, the value of x is -16/3

Option C is the correct answer.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

[tex]12^{x^2 + 5x - 4}[/tex] = [tex]12^{2x + 6}[/tex]

Answer:

90.6

Step-by-step explanation:

I think you have the first line incorrect. You show below that 10 students scored 90, so the first line is that 2 students scored 100, not 90. The line with the score of 90 is missing the number of students, but we can find it out. Call that number x for now.

Two students scored 100 each                                2

x students scored 95 on each test                         x

ten students scored 90 on each test                    10

three students score  80 on each test                    3

and one student scored 70                                 +   1

                                                                            x + 16

There are x + 16 students accounted for. The total number of students is 25.

x + 16 = 25

x = 9

9 students scored 95 on each test.

Now add up all the points scored by all students.

Two students scored 100 each  (2 * 90)                200

9 students scored 95 on each test (9 * 95)          855

ten students scored 90 on each test (10 * 90)     900

three students score  80 on each test (3 * 80)      240

and one student scored 70 (1 * 70)                      +  70

Sum of all points:                                                  2245

Now we find the average grade by dividing the sum of the points by the number of students.

average = sum/number = 2265/25 = 90.6

Answer:

the first one x value is between 2 and 3, and the y value is between -4 and -5

Step-by-step explanation:

Multiply the first equation for 4 and second equation by 3

y=1/4x-5 (x4) Then, 4y= x-20

y=-1/2x-3 (x3) Then, 2y=-x-6

From the fist equation we organize the equation as y= (x-20)/4

and we add this value of y on the second equation

2((x-20)/4)=-x-6  the number 4 goes to the other side multiply x-6 and number 2 on the other side multiply x-20

Then, 2x -40= -4x-24 then we put x in one side and numbers on the other

2x+4x = -24+40

Then. 6x = 16 then x= 2.66  => x is between 2 and 3

Then this value of X goes to the first equation y = (2.66-20 )/ 4

In a game, the odds against Carl winning are 7:5. For every 7 games he loses, there are 5 games he wins. Therefore, the probability of Carl winning is 5 divided by the total of possible outcomes (5+7), which equals to 5/12.

The subject of this question is Mathematics, specifically probability. The odds against Carl beating his friend in a round of golf are 7:5. To calculate the probability of Carl winning, we have to understand that the odds of an event occurring are the ratio of the possibility of the event happening to the possibility of the event not happening. If the odds are 7:5 against Carl winning, that means for every 7 games Carl loses, there are 5 games he wins.

To calculate the probability of Carl winning, we take the number of wins and divide it by the total number of outcomes. So the probability that Carl will beat his friend would be 5/(7+5) = 5/12.

The magnitude of a vector is found by applying the Pythagorean theorem to the horizontal and vertical changes. The formula to calculate the magnitude is given by A = sqrt(x^2 + y^2) where x and y are the vector’s horizontal and vertical displacements respectively.

The magnitude of a vector is calculated by forming a right triangle using the horizontal (x) and vertical (y) changes as the triangle's legs. The magnitude of the vector is the hypotenuse of this right triangle. This relationship is captured by the Pythagorean Theorem which states that the square of the hypotenuse (i.e. the magnitude of vector A) is equal to the sum of the squares of the other two sides (the vector's components or changes).

So, the formula for finding the magnitude of the vector (A) is:

Where x is the horizontal displacement or change, and y is the vertical displacement or change.

Find the measure of arc AB

we know that

The semi-inscribed angle measures half that of the arc comprising

so

74°=(1/2)[arc AB]

arc AB=(2)(74°)=148°

step 2

Find the measure of arc BCDA

we know that

arc BCDA+arc AB=360°

Answer: The midpoint of segment PQ is the number 2.5

note: 2.5 as a fraction is 5/2; as a mixed number 2.5 converts to 2&1/2

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

Explanation:

Apply the midpoint formula to get the midpoint of -8 and 6

We simply add up the values and divide by 2 and we get (-8+6)/2 = -2/2 = -1

So point Q is at -1 on the number line, which is exactly halfway from R to P

Focus on just points P and Q now. Apply the midpoint formula again

Q = -1

P = 6

(Q+P)/2 = (-1+6)/2 = 5/2 = 2.5

So the midpoint of segment PQ is 2.5

The decimal 2.5 can be written as the mixed number 2&1/2, showing that this new point is exactly halfway between 2 and 3.

Answer:

all numbers greater than or equal to -1

Step-by-step explanation:

Let's find the vertex.

Since the function is in factored form, I'm going to find the zeros.

The average of the zeros will give me the x-coordinate of the vertex.

I can then find the y-coordinate of the vertex by using the equation

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

Also the parabola is open up since the coefficient of x^2 is positive (or 1 in this case).

So the range has something to do with the y's. It is where the function exist for the y-values.

So the range for this one since the parabola is open up will be of the form

[y-coordinate of vertex , infinity).

So let's begin.

The zeros can found by solving (x-4)(x-2)=0.

This means we need to solve both x-4=0 and x-2=0.

x-4=0 gives us x=4

x-2=0 gives us x=2

Now the average of our x-intercepts (or zeros) is (4+2)/2=6/2=3.

So the x-coordinate of the vertex is 3. To find the y-coordinate of the vertex we are going to use y=(x-4)(x-2) where x=3.

Plug in:  y=(3-4)(3-2)=(-1)(1)=-1.

So the range is [tex][-1,\infty)[/tex]

Answer:

D.  x^2 + 8x + 12.

Step-by-step explanation:

The zeroes of the graph ( the x -intercepts) are -2 and -6  so we can write the function as (x + 2)(x + 6) = x^2 + 8x + 12.

The function y = x² + 8x + 12​ describes this graph. This is obtained by using equation of parabola at the origin and transforming the graph to the required position as in the question by using rules of transformation of linear function.

Rules of transformation of linear function are

Equation of parabola at the origin is y = x²

By the transformation we can rewrite the function in f(x+b) form;

that is ⇒ y = (x+4)² ⇒ y = x² + 8x +16

By the transformation we can rewrite the function in f(x)-b form;

that is ⇒ y = x² + 8x +16 - 4 ⇒ y = x² + 8x +12

This is the required function.

Hence the function y = x² + 8x + 12​ describes this graph.

Part one: r5 = 41.5 m , r6 = 42.75 m , r7 = 44 m , r8 = 45.25  

Part two: Max ran 399.34 m in lane one

Part three: The distance in lanes 3 and 7 are 415.04 m and 446.46 m

Part four: Max ran in the three laps 1260.84 m around the track

Step-by-step explanation:

* lets explain how to solve the problem

- The school track has eight lanes

- Each lane is 1.25 meters wide

- The arc at each end of the track is 180° , that means the arc at each

 end is a semi-circle

- The distance of the home straight for all lanes is 85 m

- The radius of the first lane is 36.5 m

∵ The width of each lane is 1.25

∴ The radius of the second lane = 36.5 + 1.25 = 37.75

- That means the radius of each lane increased by 1.25 then the

  previous lane

∴ The radius of each lane = the radius of the previous lane + 1.25

# Part one:

∵ The radius of the 4 lane is 40.25

∴ The radius of the 5th lane = 40.25 + 1.25 = 41.5 m

∴ The radius of the  6th lane = 41.5 + 1.25 = 42.75 m

∴ The radius of the  7th lane = 42.75 + 1.25 = 44 m

∴ The radius of the  8th lane = 44 + 1.25 = 45.25 m

* r5 = 41.5 m , r6 = 42.75 m , r7 = 44 m , r8 = 45.25  

- The length of each lane is the lengths of the 2 end arcs and  2

   home straight distance

∵ The arc is a semi-circle

∵ The length of the semi-circle is πr

∴ The length of the 2 arcs is 2πr

∵ The length of the home straight distance is 85 m

∴ The length of each lane = 2πr + 2 × 85

∴ The length of each lane = 2πr + 170

# Part two:

- Max ran around lane one

∵ The radius of lane one = 36.5 m

∵ The distance of each lane = 2πr + 170

∴ The distance of lane one = 2π(36.5) + 170 = 399.34 m

* Max ran 399.34 m in lane one

# Part three:

- We will chose lanes 3 and 7

∵ The distance of each lane = 2πr + 170

∵ The radius of lane 3 = 39

∵ The radius of lane 7 is 44

∴ The distance of lane 3 = 2π(39) + 170 = 415.04 m

∴ The distance of lane 7 = 2π(44) + 170 = 446.46 m

* The distance in lanes 3 and 7 are 415.04 m and 446.46 m

# Part four:

- To find the total distance that Max ran in the 3 laps ad the answers

  in part two and part three

∵ Max ran 399.34 m in lane one

∵ Max ran 415.04 m in lane three

∵ Max ran 446.46 m in lane seven

∴ The total distance of the 3 lanes = 399.34 + 415.04 + 446.46

∴ The total distance of the 3 lanes = 1260.84

* Max ran in the three laps 1260.84 m around the track

Answers:

1. 147+13=160

2. -55+(-31)= -55-31=-86

positive number and negative number= -negative number

3. 18+71=89

4. -14+21=7

Positive 7 because 21 is greater than -14

5. 12+(-56)= 12-56=-44

6. -4+18=14

7. -31+(-17)=-31-17=-48

8. 72+(-22)=72-22=50

9. 47+23=70

Part A) The rate of speed is 56 miles/ hour and

Part B) The money that waiter receive is $1.92.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Part A:

Distance traveled by Mr.Ford = 224 miles

Time taken by  Mr.Ford = 4 hours

Rate of speed can be found by

[tex]Speed = \frac{Distance}{time}[/tex]

⇒ [tex]Speed = \frac{224}{4}[/tex]

⇒ [tex]Speed = 56[/tex]

Thus the rate of speed is 56 miles/ hour

Part B:

Cost of lunch bought by Mr.Liston = $12.80

Mr.Liston gave the waiter a tip = 15%

⇒ [tex]15\% = 0.15[/tex]

Now, the money that waiter receive is

⇒ [tex]12.80(0.15)[/tex]

⇒ [tex]1.92[/tex]

Thus the money that waiter receive is $1.92.

Hence we conclude that A) the rate of speed is 56 miles/ hour and B) the money that waiter receive is $1.92.

B). 1/2

In this question, it's asking to find the probability of Ethan getting a side of the cube that is less than 4.

In this case, we know that Ethan is rolling a 6 sided number cube, meaning that the numbers on the cube will range from 1-6.

On the cube, we need to get the numbers that are less than 4.

1

2        ← These numbers are less than 4.

3  

___

4

5

6

Knowing how many numbers are less than 4, we can solve the question.

We know that there are 3 numbers less than 4. So that will be our numerator.

There are 6 numbers in total, so that will be our denominator.

We can represent probability as a fraction.

Your fraction should look like this:

[tex]\frac{3}{6}[/tex]

We are not done yet, we would need to simplify the fraction.

To simplify, we would just divide the numerator and denominator by 3.

[tex]\frac{3}{6} \div \frac{3}{3}=\frac{1}{2}[/tex]

Once you're done solving, you should get [tex]\frac{1}{2}[/tex]

This means that answer choice B). 1/2 would be the correct answer.

The probability that Ethan gets a number less than 4 by rolling the dice is 1/2.

The probability of an event is the chance of happening that particular event.

The number of events in the sample space when rolling a dice is = 6.

The number of favorable events in that sample space = Getting a number less than 4 = 3.

Therefore, the probability of this particular event is

= 3/6

= 1/2
