Calculating a projectile's vertical upward firing is possible using the function h(t)=-16t²+900t+175. 12.65<t<43.59 will the projectile be above the ground at a height more than 9000 feet.
Given that,
Calculating a projectile's vertical upward firing is possible using the function h(t)=-16t²+900t+175.
We have to find how long will the projectile be above the ground at a height more than 9000 feet.
Answers should be rounded to the closest hundredth.
The function is
h(t)=-16t²+900t+175
-16t²+900t+175>9000
-16t²+900t+175-9000>0
-16t²+900t-8825>0
The simplest method for locating a quadratic equation's roots is the quadratic formula. There are some quadratic equations that are difficult to factor, and in these cases we can quickly discover the roots by using the quadratic formula.
Gives the roots of a quadratic equation ax² + bx + c = 0.
x = [-b ± √(b² - 4ac)]/2a.
Now, We get
t= [-900 ± √((900)² - 4(-16)(-8825))]/2(-16)
t=[-900 ± √(810000-564800)]/-32
t=[-900 ± √(245200)]/-32
t=[-900 ± 495.17]/-32
First,
t=[-900 + 495.17]/-32
t=[-404.83]/-32
t=12.65
Second,
t=[-900 - 495.17]/-32
t=[-1395.17]/-32
t=43.59
Therefore, 12.65<t<43.59 will the projectile be above the ground at a height more than 9000 feet.

What is standard deviation?Standard deviation is a statistic that measures the dispersion of a data set relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of the variance by determining the deviation of each data point from the mean.
If the data points are farther from the mean, there is more variance within the data set; therefore, the wider the data is spread, the larger the standard deviation.

Identify three congruent triangles and explain how to show
that they are congruent.
The three congruent triangles in this problem are given as follows:
LPN, MPL and PLN.
What are congruent triangles?When triangles have the same side lengths, they are called congruent.
For a circle, we need to know that:
The radius of the circle is the distance of the center to any point in the circumference of the circle.The diameter of the circle is the length of a line through the center that touches two points on the circumference of the circle.Hence, for this triangle, we have that:
The following segments represent the radius: PL, PN and MP.These following segments represent the diameter: LN, MN and ML.The three triangles in this problem are given as follows:
LPN, MPL and PLN.
Since each triangle is composed by two segments that represent the radius of the circle and one segment representing the diameter, they have the same side lengths, hence they are congruent triangles.

What is a ratio ?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.
CalculationDivide the votes she received by the 6 parts of the ratio to find the value of one part of the ratio, that is

Find the measure of angle b.

43°
We conclude that the measure of angle ∠b is 43°.
What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation. A geometrical shape called an angle is created by joining two rays at their termini. In most cases, an angle is expressed in degrees. In geometry, there are several different kinds of angles.So, a measure of angle b:
Let us name the other angle as c:
∠c = 43°As we can clearly observe that ∠c and ∠b are vertically opposite angles.
Then, ∠c = ∠b.Hence, ∠b = 43°.

Step-by-step explanation:
x=30 is false.
x=y is false.
x+z=90 is true.
x+y+z=180 is false.
Answer: x=30 TRUE, x=y FALSE, y+z=90 TRUE, x+y+z=180 FALSE
Step-by-step explanation:
X=30 is true because each side is 90 degrees, and we already are given two values, 20 and 40. So to find x you do
90-(20+40) or 90-60.
This equals 30.
X=Y is false because we just saw that x is 30 degrees, and y looks to be 45 degrees. [tex]30 \neq 45[/tex]
Y+Z=90 is true because each side of the line is equal to 90 degrees and since there are two values y and z, we can do:
90/2=45.
This means that both y and z are 45 degrees and 45+45 is 90.
X+Y+Z is false because we have all of the values of them and when we add all of them together:
30 + 45 + 45
we get 120.

A- (−10,0)
B- (0,−10)
C- (8,−10)

The y-intercept of 5x+4y=-40 is (0,-10 )
A quadratic equation is expressed in its standard form as y=ax2+bx+c, where x and y are variables and a, b, and c are well-known constants. Substitute 0 for x in a quadratic equation and solve to obtain the y-intercept. The value of c in the equation is always the value of the y-intercept.
Given equation :
5x+4y=-40
To find x-intercept substitute 0 in y and solve for x
5x+4(0)=-40
5x=-40
x=8
so the x intercepts = (8,0)
To find y-intercept substitute 0 in x and solve for y

Giselle states that if bianca calls out any two side measures of her triangle and one angle measure of her triangle, giselle will be able to draw a triangle congruent to bianca's triangle. is giselle's statement sometimes, always, or never true? use concepts of rigid motion to justify your answer.
Yes, Giselle's statement is always true, she can draw a congruent triangle with the help of two sides and one angle, this rule of congruence is called the SAS property of congruency.
Giselle can create the precise triangle if Bianca gives her two sides and one angle.
Both triangles will now be congruent by SAS (side angle side) congruency.
Giselle's claim will always be accurate according to the congruency theorem.
The acronym "SAS" stands for side, angle, and side, and it makes it apparent that if any two sides and one angle of two triangles are the same, then those triangles are said to be congruent with one another.
For instance, if the triangle ABC has dimensions of 2 cm by 3 cm by 6 cm and the triangle PQR has dimensions of 4 cm by 3 cm by 6 cm and has an angle of 75 degrees, both of these triangles will be regarded as congruent triangles by the SAS theorem.

Kathlego, Tessa, and Zane all work two jobs to make ends meet due to the high cost of living.
The attorney and painter is Kathlego.
Tessa is a doctor and an engineer.
The educator and author is named Zane.
Given that,
Kathlego, Tessa, and Zane all work two jobs to make ends meet due to the high cost of living, however there are both work in the same field. Doctor, engineer, teacher, lawyer, painter, and writer are among the professions.
As soon as we realize that Zane "is not the doctor," we immediately rule off that possibility and move on to the other professions.
Given that "Zane beat Tessa and the painter at tennis," we can infer that Tessa and the painter are no longer together, which makes Kathlego the Painter.
We currently have.
Kathlego is an painter.
We can now go on to "The painter was engaged by the doctor to do the task." The fact that Zane is not the doctor and we know the painter is Kathlego gives us a huge hint. Tessa is therefore unquestionably a doctor.
We currently have:
A painter, Kathlego.
Tessa is a engineer.
We may now infer that the person is one and the same because we have "The teacher and the writer went fishing with Kathlego." We can rule out Kathlego and Tessa as the teacher and writer because they each have two jobs. Thus, we are left to assume that Zane is the instructor and author.
We currently have:
A painter, Kathlego.
Tessa is a engineer.
Both a writer and a teacher, Zane.
Consequently, the lawyer, Kathlego, is the last task left for us to complete.
Therefore,
