Answer:
Step-by-step explanation:
Angle ACB is congruent to angle ECD because they are vertical angles.
CE/CB = DC/AC because they are the corresponding sides of the similar triangles
So triangle ABC is similar to triangle DEC.

What is the surface area of this right triangular prism? Enter your answer in the box. in²
The surface area of the right triangular prism = 720 in²
What is the Surface Area of Triangular Prism?Surface area of triangular prism = (Perimeter of the triangular base × length of the prism) + (2 × triangular base area)
= (S1 +S2 + S3)L + (bh)
Thus:
S1 = 13S2 = 13S3 = 24L = 12b = 24h = 5Substitute

Show that 8x²-6x-275=0
thanks.
Answer:
(4x -25), (2x + 11)
Step-by-step explanation:
STEP1: Equation at the end of step 1
(23x2 - 6x) - 275
STEP2: Trying to factor by splitting the middle term
2.1 Factoring 8x2-6x-275
The first term is, 8x2 its coefficient is 8 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -275
Step-1 : Multiply the coefficient of the first term by the constant 8 • -275 = -2200
Step-2 : Find two factors of -2200 whose sum equals the coefficient of the middle term, which is -6 .
-2200 + 1 = -2199 -1100 + 2 = -1098 -550 + 4 = -546 -440 + 5 = -435 -275 + 8 = -267 -220 + 10 = -210 -200 + 11 = -189 -110 + 20 = -90 -100 + 22 = -78 -88 + 25 = -63 -55 + 40 = -15 -50 + 44 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -50 and 44
8x2 - 50x + 44x - 275
Step-4 : Add up the first 2 terms, pulling out like factors :
2x • (4x-25)
Add up the last 2 terms, pulling out common factors :
11 • (4x-25)
Step-5 : Add up the four terms of step 4 :
(2x+11) • (4x-25)
Which is the desired factorization
Final result :
(4x - 25) (2x + 11)

Solve the system of equations:
X+y+z=5
-3x-4y+4z=15
2x-y-4z=-8
Answer:
(x, y, z) = (3, -2, 4)
Step-by-step explanation:
The attachment shows a solution using a graphing calculator where the first equation is solved for z, and that expression is substituted into each of the other two equations. The solution to that system is (x, y) = (3, -2). Using these values in the expression for z, we find ...
z = 5 -(3 +(-2)) = 4
The solution is (x, y, z) = (3, -2, 4).
__
Your graphing calculator and/or online tools can give you the reduced row echelon form of the augmented matrix representing the system:
[tex]\left[\begin{array}{ccc|c}1&1&1&5\\-3&-4&4&15\\2&-1&-4&-8\end{array}\right][/tex]
__
If you're solving by hand, you can do the substitution described above to eliminate z from one equation. You can eliminate z from another equation by adding the last two:
-3x -4y +4(5 -x -y) = 15 ⇒ -7x -8y = -5
(-3x -4y +4z) +(2x -y -4z) = (15) +(-8) ⇒ -x -5y = 7
This pair of equations can be solved for x and y in any of the usual ways. Using the second equation to substitute for x, for example, gives you ...
-7(-5y -7) -8y = -5 ⇒ 27y = -54 ⇒ y = -2
x = -5(-2) -7 = 3
z = 5 -(3) -(-2) = 4

The number of pollinated flowers as a function of time in days can be represented by the function.
f(x)=(3)^(x/2)
What is the average increase in the number of flowers pollinated per day between days 4 and 10?
Enter your answer in the box.
So in this case f(x) is number of pollinated flowers and x is the days. First you will need to determine the number of flowers pollinated at days 4 and 10 and the days in between. f(4)= 3(4^2)= 3*16 = 48 f(5)= 3(5^2)= 3*25 =75 f(6)= 3(6^2)=3*36=108 f(7)= 3(7^2)=3*49=147 f(8)= 3(8^2)=3*64=192 f(9)= 3(9^2)= 3*81=243 f(10)= 3(10^2)=3*100=300 Now we need to find the average increase, so that will be the average of the differences between days [(75-48)+(108-75)+(147-108)+(192-147)+(243-192)+(300-243)]/6 =(27+33+39+45+51+57)/6=42

Step-by-step explanation:
Hello!
Let's see. Over here we have two sides of an equation with blank space on the right-hand side. It seems that the topic of the question is factoring.
On the left-hand side, we see that 1 factor is common between two other factors (x and -5). To simplify, we can simply add the two values.
x(y + 6) - 5(y - 6) would be the same as (x-5)(y-6) => your answer
We can check if our equation is true.
x( y + 6) - 5(y + 6) = (x-5)(y + 6)
xy + 6x - 5y -30 = xy - 5y + 6x - 30
xy + 6x - 5y - 30 = xy + 6 - 5y - 30
Both equations are the same

The probability of a student successfully completing an assignment before the due date is 0.65. If ten students are selected at random, what is the probability that at least 8 but at most 10 students will complete their assignments before the due date
Using the binomial distribution, it is found that there is a 0.2617 = 26.17% probability that at least 8 but at most 10 students will complete their assignments before the due date.
For each student, there are only two possible outcomes, either they complete the assignment, or they do not. The probability of a student completing the assignment is independent of any other student, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
The probability of a student successfully completing an assignment before the due date is 0.65, hence p = 0.65.Ten students are selected at random, hence n = 10.The probability is:
[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 8) = C_{10,8}.(0.65)^{8}.(0.35)^{2} = 0.1757[/tex]
[tex]P(X = 9) = C_{10,9}.(0.65)^{9}.(0.35)^{1} = 0.0725[/tex]
[tex]P(X = 10) = C_{10,10}.(0.65)^{10}.(0.35)^{0} = 0.0135[/tex]
Then:
[tex]P(X \geq 8) = P(X = 8) + P(X = 9) + P(X = 10) = 0.1757 + 0.0725 + 0.0135 = 0.2617[/tex]
0.2617 = 26.17% probability that at least 8 but at most 10 students will complete their assignments before the due date.
