please answer/ HELP ME I am using ALL of my points to ask this !!! Write the equation for the quadratic function in the graph.

Answer:

Step-by-step explanation:

The height of the rock as it  reaches the ground is zero i.e f(t) = 0

Substitute into the function to get t first as shown;

f(t) = -2t^2 + 15.7t

0 = -2t^2 + 15.7t

2t^2 = 15.7t

2t = 15.7

t = 15.7/2

t = 7.85secs

Get the total distance travelled by substituting t = 7.85 into the modeled equation;

Recall that:

f(t) = -2t^2 + 15.7t

f(7.85) = -2(7.85)^2 + 15.7(7.85)

f(7.85) = -123.245+123.245

Hence the total distance travelled by the rock when it reaches the ground is 0m

Graph shows the solution set for the inequality which is the correct answer would be options (A).

Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Given the system of inequalities as

y>2x-6 and y<2x +4

To determine the solutions, you first have to graph both of the lines in the problem.

y=2x-6 and y=2x +4. Then, to shift them to inequality, you have to shade the half-plane that they represent.

The solution is the space that they have in common. In this case, it will be on the right side of the graph.

Given that,

A food truck is selling 2 burritos for $5.

Solution,

We need to find the relationship between burritos and dollars.

2 burritos = $5

To find the value of 1 burrito. Divide 5 by 2 as follows :

[tex]1\ \text{burrito}=$\dfrac{5}{2}\\\\1\ \text{burrito}=$2.5[/tex]

Hence, the relation between burritos and dollars is " [tex]1\ \text{burrito}=$2.5[/tex]"

Step-by-step explanation:

Answer: a) 1.1962

after sig figs it’s 1.2

b) 0.4321

after sig figs it’s 0.43

Step-by-step explanation:

Answer:

a.) x=1.2

b.) y 0.43

Step-by-step explanation:

A. I would start with the square root on top. That equals 6.004

Divide that by 5.019.

=1.1963

B. I would start with the radical. Solving the radical results in 3.9939

Then, square 3.04

That would equal 9.2416

3.9939/9.2416= 0.4322

Answer:

C

Step-by-step explanation:

Remember the four basic power of i:

[tex]\begin{aligned}i^1&=i\\i^2&=-1\\i^3&=-i\\i^4&=1\end{aligned}[/tex]

We have:

[tex]i^{233}[/tex]

The trick here is to split the exponent into a number divisible by 4 plus the remainder. Notice that:

[tex]233=232+1[/tex]

And that:

[tex]232/4=58[/tex]

So, we can rewrite our exponent as:

[tex]=i^{4\cdot 58+1[/tex]

Using the properties of exponents:

[tex]=(i^4)^{58}\cdot i^1[/tex]

Since i to the fourth is simply 1:

[tex]=(1)^{58}\cdot i^1[/tex]

Simplify:

[tex]=1\cdot i^1[/tex]

Simplify:

[tex]=i[/tex]

Hence, our answer is C.

Answer:

11x-8

Step-by-step explanation:

First you expand 3(x-2):  3x-6

3x-6+2(4x-1)

then expand  2(4x-1): 8r - 2

3x-6+8x-2

and then simplify 3x - 6 + 8x -2: 11x - 8

11x - 8

so the answer is 11x-8

Step-by-step explanation:

Answer:

Step-by-step explanation:

Point J is midpoint of side HI as HJ = JI

Point K is midpoint of side GI as GK = KI

JK is midsegment as connects the midpoints of the sides

JK = 1/2HG as per property of midsegment

JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m

Answer:

[tex]JK=20m[/tex]

Step-by-step explanation:

It is given in the diagram that IJ = JH and IK = KG. Therefore, by the definition of a midpoint, we know that J and K are the midpoints of segments IH and IG respectively. Then, it can be concluded that JK is a midsegment by the definition of a midsegment. The Midsegment Theorem states that a midsegment connecting the midpoints of two sides of a triangle is parallel and half of the length of the third side. Thus, we know that JK is half of HG. Now, we can set up the following equation to solve for x:

[tex]JK = \frac{1}{2}HG\\6x-4=\frac{1}{2}(10x)[/tex]

Solving for x, we get:

[tex]6x-4=\frac{1}{2}(10x)\\6x-4=5x\\x-4=0\\x=4[/tex]

Therefore, [tex]JK = 6x - 4 = 6(4) - 4=24-4=20 m[/tex].

Hope this helps!

Answer:

STOP MAKIN FUNNY THINGS

Step-by-step explanation:

Answer:

Answer: 60 weeks.

Step-by-step explanation: 150 divided by 2.50 = 60

Answer:

a. See the attached picture for the graph and the excel file for how the graph is drawn.

b. The students at Maple High should choose Option A when attending more than 4 events; but they should choose Option B when attending less than 4 events

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

At Maple High, the cost to attend special events depends on whether a student has purchased a $10 discount card.

Option A: The student buys a discount card. The cost is $5 per event.

Option B: The student does not buy a discount card. The cost is $7.50 per event.

a. Graph the relationship between total cost and number of events for each option.

b. Determine the condition under which the students at Maple High should chose each option.

The explanations to the answers is now given as follows:

Let x represent the number of events and y represents the total cost.

Options A and B can therefore be written as follows:

Option A: y = 5x + 10 ……………………………. (1)

Option B: y = 7.5x ……………………………….. (2)

a. Graph the relationship between total cost and number of events for each option.

Note: See the attached picture for the graph and the excel for how the graph is drawn.

In the excel, we assume figures for x from 1 to 10 and then calculate the associated y using equations (1) and (2) above

Also, the number of events (x) is on the horizontal axis while the total cost (y) is on the vertical axis.

The graph for Option A is the blue one while the graph for Option B is the red one.

b. Determine the condition under which the students at Maple High should chose each option.

From the graph in the picture and the attached excel file, the total costs (y) for each of Options A and B ar equal when the number of events (x) is equal to 4.

It can bee observed that when the number of events (x) is greater than 4, the total cost (y)  of Option A is less than the total cost (y) of Option B. Under this condition, Option A should be chosen.

On the other hand, when the number of events (x) is less than 4, the total cost (y)  of Option A is greater than the total cost (y) of Option B. Under this condition, Option B should be chosen.

Therefore, the students at Maple High should choose Option A when attending more than 4 events; but they choose Option B when attending less than 4 events.

Answer:

1438.6 days

Step-by-step explanation:

We are told in the above question that:

228,000 people get infected per day. Hence, how long it would take for 328,000,000 people to be infected is calculated as:

228,000 people = 1 day

328,000,000 people = x days

Cross Multiply

228,000 people × x days = 328,000,000 people × 1 day

x days = 328,000,000 people × 1 day/228,000 people

x days = 1438.5964912 days

Approximately = 1438.6 days

Therefore, it would take 1438.6 days for 328,000,000 people to be infected.

Answer:

The true statement is h < k ⇒ (3)

Step-by-step explanation:

∵ The equation of the graph is y = [tex]\sqrt{x+h}[/tex] + k

∵ (-h, k) are the coordinates of its vertex point

∵ -h is the x-coordinate of the vertex point

∵ x-coordinate of the vertex point is -3

∴ -h = -3

→ Divide both sides by -1

∴ h = 3

∵ k is the y-coordinate of the vertex point

∵ y-coordinate of the vertex point is 4

∴ k = 4

∵ 3 < 4

→ That means h is smaller than k

∴ h < k

∴ The true statement is h < k

Step-by-step explanation:

The equation of the diagram would be 99=5w+4

#2-the number Andre earned for the 5 times babysat, each earning the same, would be represented by the 5w. The extra 4 dollars would be represented by the 4. And the $99 for the total would be represented by the 99.

#3- the cost of the parking would be represented by the 4. The 5 tickets that they paid for would be represented by the 5w. And the 99 would be the total.
