, the
Triangle ABC is similar to triangle QPR due to the transformations reflection, the triangles are similar by side-angle-side similarity theorem.
How to Identify similar triangles?Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.
- Rotation means that it rotates or turns the pre-image around an axis with no change in size or shape
- Reflection means that it flips the pre-image and produces the mirror-image with no change in size or shape or orientation
- Translation means that it slides or moves the pre-image with no change in size or shape but has changes in only the direction of the shape
- Dilation means that it stretches or shrinks the pre-image.
Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion. It should be noted that, corresponding angles are congruent.
Thus, we conclude that triangle ABC and triangle QPR are similar triangle based on the side-angle-side similarity theorem.

Determine the seating capacity of an auditorium with 34 rows of seats if there are 16 seats in the first row, 20 seats in the second row, 24 seats in the third row, and so on.
Answer:
2788.
Step-by-step explanation:
This is represented by an arithmetic series with first term 16 and common difference 4.
The number of rows n = 34.
The capacity
= sum of 34 terms
= (34/2)[2*16 + 4(34-1)]
= 2788.
Answer:
2788
Step-by-step explanation:
16,20,24,.. This is a arithmetic progression with common difference of 4
Sn=? , d=4 , a =16 , n=34[tex]Sn=\frac{34}{2}[2(16)+(34-1)4] \\\\Sn=17[32+33(4)]\\\\Sn=17[164]\\\\Sn=2788[/tex]

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( √14 - √3 ) ( √12 + √7 )
On simplifying , we get
A = √14 ( √12 ) - √3 ( √12 ) + √14 ( √7 ) - √3 ( √7 )
A = √168 - √36 + √98 - √21
On further simplification , we get

help me please eeeeeeeeee
Answer:
A
Step-by-step explanation:
Fundamental Theorem of Algebra:
This states that any polynomial with degree n will have n solutions which are real or complex.
Since this function you gave has 4 zeroes, this function has to have at at least a degree of 4. The reason I say at least, is because of something called multiplicity. When a zero has an even multiplicity it will have a turning point at the zero, if it has an odd multiplicity it will pass the x-axis. So assuming each zero only has a multiplicity of 1, then this will have at least a degree of 4. It also might have complex zeroes which still count as zeroes.
End Behavior of Polynomial Functions:
So this is pretty easy to remember, but if the leading coefficient is positive, then the end behavior to the right will go up, if it's negative it will go down. Now the next thing to know is an odd degree means that the end behavior will go in opposite directions. So if the right goes up, then the left side will be going down and vice verse. if it's an even degree then the two opposite sides will go in the same direction.
In this case both ends are going down, in the same direction. This means that the leading coefficient is negative and the degree is even.
Using these two things, we can exclude answers
B can't be the answer, it only has 3 zeroes, this has at least 4.
C can't be the answer, it has an odd degree so the end behaviors would go in opposite directions
D can't be the answer, it has a positive leading coefficient so the right side would be going up
This means the only possible equation is A which has at least a degree of 4, negative leading coefficient, and even degree.

Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A F, B D, and C E. The length of line segment A G is 19 x + 14 and the length of line segment D G is 9 x + 2.
G is the centroid of triangle ABC.
What is the length of GF?
units
Based on the calculations, the length of GF is equal to 26 units.
How to find the length of GF?In Geometry, the centroid of any triangle always divides the lines in a ratio of 2:1. Thus, G divides line B F as follows:
2DG = BD
2(9x + 2) = 40
18x + 4 = 40
18x = 40 - 4
x = 36/18
x = 2.
Similarly, G divides line A F as follows:
2GF = A F
GF = A F/2
GF = (19x + 14)/2
GF = (19(2) + 14)/2
GF = 52/2
GF = 26 units.

Currently, Netflix has 93 000 subscribers. Netflix subscriptions are decreasing by 2.2% per day. How many subscribers are there after 5 days?
There are 83210 subscribers after 5 days
How to determine the number of subscribers?The given parameters are:
Initial, a = 93000Rate, r = 2.2%The number of subscribers each day is calculated as:
f(n) = a * (1-r)^n
This gives
f(n) = 93000 * (1 - 2.2%)^n
Evaluate the difference
f(n) = 93000 * 0.978^n
At 5 days, we have:
f(5) = 93000 * 0.978^5
Evaluate
f(5) = 83210
Hence, there are 83210 subscribers after 5 days

In a New York State daily lottery game, a sequence of five digits (not necessarily different) in the range 0-9 are selected at random. Find the probability that four of the five digits are the same.
The probability that four of the five digits are the same is 0.036.
There are 10,000 (10*10*10*10) possible sequences. There are 4C3 ways, 4, of having exactly three digits be the same value. The differing digit can be any of the four positions. There are 10P2 ways, 90 (10*9), to choose the digits of the sequence since we have 10 choices for the digit to be repeated, then 9 more options or the differing digit. The product of the combination arrangements and permutation selection, 4*90, shows there are 360 sequences with three of the same digit. Thus the probability is 360/10,000 or 0.036 or 3.6%.

In the equation y=kx, where k is a constant. when y=12, then x=5. when y=60, what does x equal?
Answer:
If y = 60 then x = 25
Step-by-step explanation:
You know that when y = 12 then x = 5
So when y = 60, x = 25
The reason for this is because 12 * 5 = 60.
Which means that since the y = 12 was multiplied by 5, the x = 5 should be multiplied by 5 too.
Since 5 * 5 = 25, then we know that if y = 60, then x will equal 25.
