a. x = 0.384 cm

b. x = 0.48 cm

c. x = 2.4 cm

d. x = 3.75 cm

Answer:

Explanation:

1. Function for the height (given):

    [tex]h(t)=-16t^2+48t+100[/tex]

2. Type of function

That is a quadatic function, whose graph is a parabola that opens downward.

The maximum of the function, i.e. the maximum height, is the vertex of the parabola.

The vertex of a parabola with the genral equation   [tex]y=ax^2+bx+c[/tex]  is at the x-coordinate

                       [tex]x=-b/(2a)[/tex]

3. Time to achieve the maximum height

Substitute b with 48 and a with - 16:

        [tex]t=-48/(2(-16))=48/32=3/2=1.5[/tex]

Then, time when the object achieves the maximum height it 1.5s

4. Maximum height:

Replace t with 1.5 in the equation, to find the maximum height, h(1.5)

     [tex]h(1.5)=-16(1.5)^2+48(1.5)+100=136[/tex]

Then, the maximum height is 136 ft

Step-by-step explanation:

Option C: x = 5.5 is the value of x

Explanation:

Given that CD, AE, an BF are the medians of the triangle ABC

Also, given that [tex]AM = 4x - 5[/tex] and [tex]ME=x+3[/tex]

We need to determine the value of x.

Since, we know that the centroid divides the median in the ratio 2 : 1

Hence, we have,

[tex]AM=2\times ME[/tex]

Substituting the values, we get,

[tex]4x-5=2(x+3)[/tex]

Simplifying, we get,

[tex]4x-5=2x+6[/tex]

Subtracting both sides of the equation by 2x, we have,

[tex]2x-5=6[/tex]

Adding both sides of the equation by 5, we have,

[tex]2x=11[/tex]

Dividing both sides of the equation by 2, we get,

[tex]x=5.5[/tex]

Therefore, the value of x is 5.5

Hence, Option C is the correct answer.

Approximately 67% there are 6 numbers and 4 of them are even So you have to divide 100 and 6 then multiply the answer by 4

Answer:

20 ft.

Step-by-step explanation:

There are two different (yet similar) ways to solve this problem:

a. Pythagorean theorem

b. Pythagorean triplet recognition

With option "a", you set it up:

12² + 16² = x²

144 + 256 = x²

400 = x²

x = 20

But, the arguably "easier" way to find out the distance is to use the Pythagorean's triplet recognition.

We know that the most common right triangle is the 3-4-5 right triangle.

If you take the three side lengths, and multiple them by the same thing, those are the sides to another right triangle.

ex. 3-4-5  *   5

15-20-25 are the sides of another right triangle!

This also means that if you have a triangle that has the sides 15, 20, and 25, you immediately know it's a right triangle.

When we look at 12 and 16, we know they are the legs of the triangle.

We also know that if we multiply 4 times 3 and 4, it will equal 12 and 16.

So what's 5 times 4? 20!

Final answer:

To find how far the bird will fly to the top of the tree, we use the Pythagorean Theorem. By squaring the height of the tree and the distance from the bird to the tree, we find that the hypotenuse, or the distance the bird will fly, is 20 feet.

Explanation:

The question asks about the distance a bird will fly from the ground to the top of a tree, which involves the application of the Pythagorean Theorem to solve for the hypotenuse of a right triangle. The tree's height (12 feet) represents one leg of the right triangle, and the distance from the bird to the tree (16 feet) represents the other leg. To find the distance the bird flies (the hypotenuse), we use the equation:

a² + b² = c²

Where ‘a’ and ‘b’ are the lengths of the legs, and ‘c’ is the length of the hypotenuse. Now we can calculate it:

12² + 16² = c²

144 + 256 = c²

400 = c²

[tex]\sqrt{400}[/tex] = c

20 feet = c

Therefore, the bird will fly 20 feet to reach the top of the oak tree.

Answer:

Max value for t is -1 and minimum value for t is -5

Step-by-step explanation:

Make two inequalities in regards to absolute value and solve both for t:

t+3<=2 and t+3>=-2

t<=-1     and   t>=-5

The compound inequality would be -1>=t>=-5

Solving the absolute value inequality, it is found that:

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

[tex]-a \leq f(x) \leq a[/tex]

In this problem, the inequality is:

[tex]|t + 3| \leq 2[/tex]

Thus, the solution is:

[tex]-2 \leq t + 3 \leq 2[/tex]

[tex]-2 \leq t + 3[/tex]

[tex]t + 3 \geq -2[/tex]

[tex]t \geq -5[/tex]

[tex]t + 3 \leq 2[/tex]

[tex]t \leq -1[/tex]

While Game 1 offers a steady 200 points per score, Game 2's point doubling system will eventually surpass Game 1's linear growth, leading to higher earnings in Game 2 over time.

To decide in which game you will earn more points, let's consider the point growth in both games. In Game 1, you receive a constant 200 points every time you score. This represents a linear growth.

However, in Game 2, your points double every time you score, starting from 2 points (2, 4, 8, 16, and so on).

When comparing linear growth to exponential growth, exponential growth will eventually outpace linear growth. Initially, Game 1 will give you more points (as 200 is greater than 2, 4, 8).

However, after a certain number of scores, Game 2 will start to give you more points per score. Once you've doubled a few times, the number of points you earn in Game 2 will surpass the constant 200 points reward of Game 1.

Answer:

Step-by-step explanation:

Given the simultaneous equation

3x+4y=15. Equation 1

3x-y=30. Equation 2

Using elimination method

Sutract equation 2 from 1

Then, will have

3x-3x+4y--y=15-50. -×-=+

4y+y=-15

5y=-15

Divide Both sides by 5

y=-15/5

y=-3

From equation 2

3x-y=30

3x--3=30

3x+3=30

3x=30-3

3x=27

Divide both side by 3

x=27/3

x=9

Then, x=9 and y=-3

Answer:

x=7 y=-9

Step-by-step explanation:

Use a system of equations to solve.

3x-y=30 changes to y=-30+3x

This can then be substituted into the other equation.

3x+4(-30+3x)=15

solve for x

X=7

Now use 7 in the other equation.

y=-30+x(7)

y=-9

The system of linear equations represented on the graph has infinitely many solutions.

To determine the number of solutions for the system of linear equations, we can start by solving the equations. We can solve the first equation for y to get y = x + 2. We can substitute this expression for y into the second equation and then solve for x. By substituting y = x + 2 into -3x + 3y = 6, we get -3x + 3(x + 2) = 6. Simplifying this equation gives us -3x + 3x + 6 = 6, which simplifies further to 6 = 6. This equation is always true, which means there are infinitely many solutions for the system of linear equations. The two equations represent the same line, and any point on this line is a solution to the system.

Answer:

Around 16 hours

(16 hours, 2.74 minutes)

Step-by-step explanation:

In 3 hours,

Rachel has managed: 3 ÷ 5/2 = 6/5

In 6 hours,

Jenna has managed: 6 ÷ 9 = ⅔

Till 9 am,

Thomas and Paul have been woking and maneged:

(9 ÷ 7) ÷ (9 ÷ 2) = 81/14

Total works done in first 9 hours:

6/5 + 2/3 + 81/14 = 1607/210

Remaining work:

15 - 1607/210

= 1543/210

Rachel, Paul and Thomas complete this remaining job together in next 't' hours

(t/2.5) + (t/2) + (t/7) = 1543/210

73t/70 = 1543/210

t = 7.0456621 hours

Or 7 hours 2.74 mins

Overall, it will take them around 9+7 = 16 hours to complete the task

They'll be done at 1600

Which is 4 pm

Final answer:

It will take them approximately 22 hours and 21 minutes to build 15 tractors. The tractors will be finished at around 10:21 PM.

Explanation:

To find out how long it will take them to build 15 tractors, we need to first calculate how many tractors each person can build in 1 hour. Jenna can build 1/9 of a tractor in 1 hour, Thomas can build 1/7 of a tractor in 1 hour, Rachel can build 2/5 of a tractor in 1 hour, and Paul can build 1/2 of a tractor in 1 hour.

Adding up the fractions, we get 1/9 + 1/7 + 2/5 + 1/2 = 85/126. Therefore, in 1 hour, all four of them can build 85/126 of a tractor. To build a total of 15 tractors, we need to find how many hours it will take to build 126/85 of a tractor.

Therefore, it will take them (126/85) × 15 = 22.35 hours to build 15 tractors. Since they started building at midnight, it will take them about 22 hours and 21 minutes, so they will finish building the tractors at around 10:21 PM.

Answer:

Step-by-step explanation:

Given that,

Slope of line is 8

m=8

And we are given two points where the line pass through

(x1,y1) = (9,v). ; x1=9, y1=v

(x2,y2)= (8,2). ; x2=8, y2=2

The slope of a line is given as

m=∆y/∆x

m=(y2-y1)/(x2-x1)

8=(2-v)/(8-9)

8=(2-v)/(-1)

Cross multiply

8×-1=2-v

-8=2-v

Subtract 2 from both sides

-8-2=2-v-2

-10=-v

Divide both sides by -1

-10/-1=-v/-1

Note, -÷-=+

10=v

Then v=10

We can write this as an expression:

[tex]\frac{2-v}{8-9}=8[/tex] → [tex]\frac{2-v}{-1}=8[/tex]

Now, lets solve for v.

[tex]\frac{2-v}{-1}=8[/tex]

~Multiply -1 to both sides

[tex]\frac{2-v}{-1}[/tex] * -1 = 8 * -1

~Simplify

2 - v = -8

~Subtract 2 to both sides

2 - 2 - v = -8 - 2

~Simplify

-v = -10

~Divide -1 to both sides

-v/-1 = -10/-1

~Simplify

v = 10

When graphing in this problem we will be graphing the equation y=2x+8, where the 2x represents the fee for each ride, and 8 represents the fee to get in.

When graphing y=2x+8, you 8 is where it is going to be on the y-intercept, so the first step is to put a dot on the 8 on the y-axis. Then from that point (y-intercept) you would go up 2 and over 1, because that is your slope (2x), then you continue on with your slope up 2 and over 1, until you reach the top of your graph.

Answer:

D) 8sqrt(2)

Step-by-step explanation:

h² = 8² + 8²

h² = 2(8²)

h = 8sqrt(2)

The area quadrupled. If the original square's perimeter is 20, each side length must be 5. The new square has double the perimeter, so it's 40. This means each side of the new square must be 10.

The formula for area in a square is base x height.

Square 1 area: 5x5 = 25

Square 2 area: 10x10 = 100

100/25 is 4, so the original square's area is 4 times smaller than the new square.
