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:
-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.
Find the mean and median of this list: 21, 18, 24, 19, 18, 18, 18, 19, 21, 24.
Answer: mean-20 and median-(19+19)/2 = 19
Step-by-step explanation:
Answer:
Mean→ 20
Median→ 19
Step-by-step explanation:
Mean: is the sum divided by the number of terms.
Median: Arrange the numbers in ascending order and the median is the middle value.

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.
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.
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°
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?
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
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]

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical form.
PLEASE show me how to put them in the box
Answer:
c=4√2
Step-by-step explanation:
Sine the triangle is a right triangle you can use the Pythagorean theorem. a^2+b^2=c^2
(4)^2+(4)^2=c^2
16+16=c^2
32=c^2
c=√32
c=4√2

Find all the missing angles: a, b, c, d.
Explain if you can, if it’s right I’ll give BRAINLIST.
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

Answer:Function to be graphed is,
h(x) = 2(x - 3)²
Function 'h' is a quadratic function.
Since, the coefficient of the leading term (term with the highest power) is positive, parabola will open upwards.
Both the ends of the parabola will be upwards (towards positive infinity).
As x approaches to negative infinity, h(x) approaches to positive infinity.
As x approaches to positive infinity, h(x) approaches to positive infinity.
Step-by-step explanation:
Evaluate the expression when h = 12, p = 7

a cylindrical paint can has a diameter of 12 centimeters and a hieght of 16 centimeters. What is the colsest to the volume of the paiint can in cumbic meters
Answer: [tex]1809.792\ m^3[/tex]
Step-by-step explanation:
Given
The diameter of the cylinder is [tex]d=12\ cm[/tex]
height of the cylinder is [tex]h=16\ cm[/tex]
The volume of a cylinder is given by
[tex]V=\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\pi \times 6^2\times 16\\\Rightarrow V=3.142\times 576\\\Rightarrow V=1809.792\ m^3[/tex]
The volume of the cylinder is [tex]1809.792\ m^3[/tex]

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

I believe since you are looking for the angle of M<ABC, you just add both 120 and 25 together, since they practically share a point.
So 120 + 25 = 145
So I guess 145 would be your answer.
I remembered this type of problem from Geometry.
