Using The Graph, Determine The Coordinates Of The Roots Of The Parabola.

Answers

Answer 1

Answer:

(7, 0) and (3,0)

Step-by-step explanation:

On the graph, the parabola crosses the x-axis at two points. The two points are called the roots. And since they cross at (7, 0) and (3, 0), they are our roots. Hope this helps!

Answer 2

Answer:

-7 and -3

Step-by-step explanation:

Hello!

The roots of a parabola are the points at which the graph intersects the x-axis. The x-axis is located at y = 0.

As you can see, the graph's vertex is below the x-axis and opens upwards. This means the graph has 2 roots.

The points of intersection are:

(-7,0)(-3,0)

The roots of the parabola are -7 and -3.

A radio station announces one listener's name between 8:10:00 and 8:21:59 every morning. If you turn the radio on at 8:18:00, what are the chances that you missed the announcement? Round your answer to the nearest hundredth.

Answers

Answer:

[tex]Pr = 0.67[/tex]

Step-by-step explanation:

Given

[tex]Start = 8:10:00[/tex]

[tex]End = 8:21:59[/tex]

[tex]You = 8:18:00[/tex]

Required

Chances that you missed the appointment

First, calculate the number of minutes of the radio station

[tex]n = End - Start[/tex]

[tex]n = 8:21:59 - 8:10:00[/tex]

[tex]n = 11\ min\ 59\ secs[/tex]

Convert to seconds

[tex]n = 719[/tex]

Since you turn on at 8:18:00, then you've missed the broadcast from the start till 8:18:00

So, we have:

[tex]Missed = 8:17:59 - 8:10:00[/tex]

[tex]Missed = 7\ mins\ 59\ secs[/tex]

Convert to seconds

[tex]Missed = 479[/tex]

The probability that you missed is:

[tex]Pr = \frac{Missed}{n}[/tex]

[tex]Pr = \frac{479}{719}[/tex]

[tex]Pr = 0.67[/tex]

Two angles x and y are complementary - which means their
angles add up to 90 degrees. Angle y is 20 degrees less
than angle x. Find the measure of each angle.

Answers

Answer:

X=55° Y=35°

Step-by-step explanation:

X+Y=90°

Y= x-20

(X-20)+X=90°

2X-20=90°

2X=110°

X=55°

55°+Y=90°

Y=35°

12° is the correct answer

It takes 8 workers 12 days to build a wall work out how many days it would take 3 workers to complete the same job

Can anyone please help?

Answers

Answer: 4.5 days or 4 1/2 days

Step-by-step explanation: We can use cross product property, to solve this. Workers to Days remember that  

❍ Question -:

If 8 workers can build a wall in 12 days. How many days will it take 3 workers to build the same wall ?

❍ Explanation -:

In this question we are provided that 8 workers can finish a piece of work in 12 days. We are asked to calculate how many days it will take 3 workers to complete the same work.

We can solve this question using two methods :

Unitary MethodMethod of proportion

[tex] \small \green{ \underline{ \underline{\bf{ Unitary \: Method}}}}[/tex]

8 workers can build a wall in 12 days

1 worker can build a wall in 12 × 8 days

3 workers can build a wall in [tex]\dfrac{12 × 8}{3}[/tex] = 32 days.

Hence, If 8 workers can build a wall in 12 days. 3 workers will take 32 days to build the same wall.

[tex] \rule{47mm}{4pt}[/tex]

[tex] \small \orange{ \underline{ \underline{\bf{ Method \: of \: proportion }}}}[/tex]

Let us assume that 3 workers can build a wall in x days.

[tex] \begin{array}{ cc } \bf{Number \: of \: workers} & \bf{Number \: of \: days} \\ 8 &12 \\ 3&x \end{array}[/tex]

Ratio of workers = Inverse ratio of days

[tex] \small\sf{ 8 : 3 :: x : 12}[/tex]

Product of mean = Product of extreme

[tex] \rightarrow \small\rm{ 3 \times x = 8 \times 12}[/tex]

[tex] \rightarrow{x \: }\small\sf{ = \dfrac{8 \times 12}{3} = 32 \: days } [/tex]

Hence, If 8 workers can build a wall in 12 days. 3 workers will take 32 days to build the same wall.

[tex] \rule{73mm}{5pt}[/tex]

f(x) = 1, so we make the entire equation equal 1.

To make x by itself subtract 7 from both sides

-6 = sqrt(x)

Square both sides to remove sqrt from x.

Answer:

a= 180-60-55=65

we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.

b=180-90-65=25

the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.  

c=25

c is 25, because two angles on both sides of a X is the same

Does the tallest can always hold the greatest volume? Explain your answer!

Answers

Alrighty, so,  you know how young children often believe that a taller container will have a greater volume than a shorter container? Even after seeing that both containers hold the same amount, some children will still think the taller container holds more. It may take measuring the water a few times before they get it.

If it overflows, the first container is bigger, or is able to hold more water. If all of the water from the first container can be poured into the second container without completely filling it, then the second container holds more water.

The tallest container holds the most liquid. Identical containers can have a different capacity.
