Step-by-step explanation:
you should use the pythagorean theorem to solve this!
a^2 + b ^2 = c^2
3^2 + 3^2 = c^2 (i got 3 because it goes down three, and over three)
9 + 9 = c^2
18 = c^2
the square root of 18 is 4.24
therefore, the distance between C and D is 4.24.

The sequence of transformations will verify that △EFG and △E'F'G' are congruent is; C) △EFG is moved onto △E'F'G' after rotating 270 degrees counterclockwise around the origin, and then reflecting across the x-axis
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs), etc.
For triangle △EFG and △E'F'G' to be congruent, we must first rotate 180° counterclockwise around the origin and then move EFG onto E'F'G'H'.
This proof of congruency is reflected across the y-axis.

Answers
Answer:

Let x be the number of days.
Since there is a pattern, that 1 person is infected and infects two. Then two infects 4.

Answer:
volume of a cone = 2.82πinches³( nearest hundredth)
Step-by-step explanation:
given that the diameter of a cone = 2 3/8
diameter = radius x 2
radius = diameter /2
radius = 19/8/2 = 1.1875
height of the cone = 6inches
volume of the cone = ?
recall that the formulae for calculating the volume of a cone = πr² h/3
volume of a cone = πr² h/3
volume of a cone = π (1.1875)² x 6/3
volume of a cone = π1.410 x 2
volume of a cone = 2.8203πinches³
volume of a cone = 2.82πinches³( nearest hundredth)

Which expression has an equivalent value to x2 + 9x + 8 for all values of x?
(x + 1)(x + 8)
(x + 2)(x+6)
(x + 4)(x + 4)
(x + 5)(x + 4)
Answers
Answer:
(x + 1)(x + 8)
Step-by-step explanation:
I graphed the equation on the graph below to find the x values.
We can find this by expanding the brackets and seeing if the resultant expression is x² + 9x + 8. We can expand it using the FOIL method (first, outside, inside, last)
(x + 1)(x + 8)
x × x = x² (first)
x × 8 = 8x (outside)
1 × x = x (inside)
1 × 8 = 8 (last)
Adding these all together gives us x² + 8x + x + 8 = x² + 9x + 8, which is the original expression.

What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The space enclosed by the boundary of a plane figure is called its area.
The area of a figure is the number of unit squares that cover the surface of a closed figure.
Given that, a figure having the area of one of the small right triangles outlined in blue is A cm² while the area of the square outlined in red is B cm²
The total area = the sum of the area of the 4 triangles and the square,
= A + A + A + A + B = 4A + b

Bottom left graph
Step-by-step explanation:
Since the y-coordinates are the same, but the x-coordinates are opposites, it is a reflection across the y axis.
Therefore, the bottom left graph is correct.
Answer: The Bottom Left Graph
Step-by-step explanation:
The Y coordinates are the same number, therefore, when you find the coordinates of the points, the y must be equal, making them the same height on a graph. The X coordinates on the graph must be opposites, therefore, the two dots have to be equidistant from the Y axis. The only graph that has two dots at the same height and is equidistant from the Y axis is the graph at the bottom Left Corner.

The pilot of a glider plane wants to estimate his altitude. He picks a landmark ahead and measures the angle of depression to be 20 degrees. He flies another 800 feet towards the landmark, remaining at the same altitude. The angle of depression from his new location to the same landmark is now 21.4 degrees. What is the glider's altitude?
Answers
Answer:
4,000 ftExplanation:
The figure attached shows sketches the situation described.
You have two right triangles.
For the right triangle with the plane on the position A, you can write:
tan(20º) = H/(800 + x)⇒ H = (800 + x) tan(20º)
For the right triangle with the plane on the position B, you can write:
tan(21.4º) = H/x⇒ H = x tan(21.4º)
To solve, equal both equations:
x tan(21.4º) = (800 + x) tan(20º)x tan(21.4º) = 800 tan(20º) + x tan(20º)x = 800 tan(20º) / ( tan(21.4º) - tan(20º) )x = 10,426.9 feetSubstitute in the equation H = x tan(21.4º)
H = 10,426.899856 × tan(21.4º) = 4,086 ftRounding to one signficant figure that is 4,000 ft.

Explanation:
Each circle has a radius of 'a'. So r = a.
The area of each circle is pi*r^2 = pi*a^2
The area of each square with side length b is b^2
The two stacks have the same volume only when the circle area is equal to the square area, so whenever pi*a^2 = b^2 is true.
Solving for b leads to b = sqrt(pi*a^2) = sqrt(pi)*a
The stacks must also be the same height for the volumes to be the same, so m = n as well.

in a class there are 8 students who play football and cricket 4 students who do not play football or cricket 14 students who play football 20 students who play cricket find the probability that a student chosen at random plays football or cricket or both
Answers
Answer:
Step-by-step explanation:
hello :
here is an solution :
The probability that a student chosen at random plays football or cricket or both is approximately 0.8667, or 86.67%, after considering the number of students playing each sport and accounting for those who play both.
To calculate the probability that a student chosen at random plays football or cricket or both, we can use the concept of probability along with a Venn diagram to organize our information.
First, we need to calculate the total number of students that play at least one of the sports. We know that 8 students play both football and cricket, 14 students play football, and 20 students play cricket. However, the 8 students that play both sports are included in the totals for both football and cricket. Therefore, to find the number of students who play at least one sport, we need to subtract the students counted twice because they play both sports:
Total playing football or cricket or both = (Number playing football) + (Number playing cricket) - (Number playing both)
= 14 + 20 - 8
= 26 students
We also know there are 4 students who do not play football or cricket. To find the total number of students, we add the number of students who play either sport to those who play neither:
Total number of students = 26 (playing sports) + 4 (not playing any sports)
= 30 students
The probability that a student chosen at random plays football or cricket or both is calculated by dividing the number of students who play either sport by the total number of students:
P(playing football or cricket or both) = Number of students playing sports / Total number of students
= 26 / 30
= 0.8667 (rounded to four decimal places)
The probability is approximately 0.8667, or 86.67%.
