Is it possible to have a triangle with the following sides give reason
3cm 4cm 5cm
4cm 5cm 6cm
Answer: Yes,
Step-by-step explanation:
Because since there are two numbers that are the same and numbers that are different, you can make a triangle out of it. Since a triangle has twi sides that have the same length and a side that has a different length.
Example: 4cm 4cm
Help pleaseeeee......!
Answer:
D.) QS ≅ NR
Step-by-step explanation:
Congruency between QS and NR can be assumed because the angles they make at points T and U are both right angles and the 6.7 seems to be indicating the same length of the lines (?)
Nonetheless, they look to be about equal in size and angle, so D.) QS ≅ NR is your best answer.

c) f (p+4)
9514 1404 393
Answer:
26127 (see comment)3p^2 +22p +40Step-by-step explanation:
In each case, put the function argument where the variable is and do the arithmetic (or algebra).
a) f(-9) = 3(-9)^2 -2(-9) = 3·81 +18 = 261
__
b) g(-3) = -8(-3)-(-3) = 24 +3 = 27
__
c) f(p+4) = 3(p+4)^2 -2(p+4)
= 3(p^2 +8p +16) -2p -8
= 3p^2 +22p +40
_____
Additional comment
The form of g(x) is unusual, leading us to suspect it might be ...
g(x) = -8x^2 -x
In that case,
g(-3) = -8(-3)^2 -(-3) = -8·9 +3 = -69

hello help me with this question thanks in advance
[tex]\bold{\huge{\underline{ Solution \:1}}}[/tex]
Yes, ΔEDF and ΔBCA are similarIf we look at the both the triangles then the
[tex]\sf{ {\angle} E = {\angle}B }[/tex][tex]\sf{ {\angle} F = {\angle}A }[/tex]From above, we can conclude that :-
Both the triangles are similar by AA Similarity
Hence, Option A is correct.
[tex]\bold{\huge{\underline{ Solution \:2}}}[/tex]
Let consider the given triangle be ABC and the line that divides the triangle consider it as DE
Here, DE || BCSo,
[tex]\sf{\dfrac{ AD }{ AB }}{\sf{ = }}{\sf{\dfrac{AE}{AC}}}{\sf{=}}{\sf{\dfrac{DE}{BC}}}[/tex]Therefore, ΔABC similar to ΔADE by SSS congruence similarity criterion. Now,We have to find the value of x
In ΔABC, By using BPT theorem
If the line is drawn parallel to one side of the triangle which intersect the other two sides at specific points then the other two sides are in proportion .That is,
[tex]\sf{\dfrac{ AD }{ AB }}{\sf{ = }}{\sf{\dfrac{DE}{BC}}}[/tex]
Subsitute the required values,
[tex]\sf{\dfrac{ 6 }{ 6 + 4 }}{\sf{ = }}{\sf{\dfrac{8}{x}}}[/tex]
[tex]\sf{\dfrac{ 6 }{ 10 }}{\sf{ = }}{\sf{\dfrac{8}{x}}}[/tex]
[tex]\sf{\dfrac{ 3 }{ 5 }}{\sf{ = }}{\sf{\dfrac{8}{x}}}[/tex]
[tex]{\sf{ x = 8{\times} }}{\sf{\dfrac{5}{3}}}[/tex]
[tex]{\sf{ x = }}{\sf{\dfrac{40}{3}}}[/tex]
[tex]{\sf{ x = 13}}{\sf{\dfrac{1}{3}}}[/tex]
Hence, Option C is correct
[tex]\bold{\huge{\underline{ Solution \:3}}}[/tex]
Here,
SRT similar to BACFor x,
By using BPT theorem,
[tex]\sf{\dfrac{ AB }{ RS }}{\sf{ = }}{\sf{\dfrac{BC}{ST}}}[/tex]
Subsitute the required values,
[tex]\sf{\dfrac{ 2 }{ 4 }}{\sf{ = }}{\sf{\dfrac{x}{6}}}[/tex]
[tex]\sf{\dfrac{ 1 }{ 2 }}{\sf{ = }}{\sf{\dfrac{x}{6}}}[/tex]
[tex]\sf{ x = }{\sf{\dfrac{6}{2}}}[/tex]
[tex]\sf{ x = 3 }[/tex]
Thus, The value of x is 3
For y
Again by using BPT theorem,
[tex]\sf{\dfrac{ AB }{ RS }}{\sf{ = }}{\sf{\dfrac{AC}{RT}}}[/tex]
Subsitute the required values,
[tex]\sf{\dfrac{ 2 }{ 4 }}{\sf{ = }}{\sf{\dfrac{5}{y}}}[/tex]
[tex]\sf{\dfrac{ 1 }{ 2 }}{\sf{ = }}{\sf{\dfrac{5}{y}}}[/tex]
[tex]\sf{ y = 5{\times}2 }[/tex]
[tex]\sf{ y = 10 }[/tex]
Thus, The value of y is 10
Hence, Option A is correct.

Have an amazing day!!!
PLEASE RATE!!
Hello.
Please remember that equivalent means equal.
So we need to find 4 fractions that are equal to
[tex]\displaystyle\frac{4}{7}[/tex]
There are infinitely many fractions equal to the given fraction; we need just 4 of them.
First, let's multiply the numerator (4) and the denominator (7) times 2:
[tex]\displaystyle\frac{8}{14}[/tex]
Now, let's multiply the numerator and denominator of this fraction by 2:
[tex]\displaystyle\frac{16}{28}[/tex]
Multiply by 2 once more:
[tex]\displaystyle\frac{32}{56}[/tex]
I hope it helps.
Have an outstanding day. :)

Answer:
9. vertex: (1, -2)
10. dashed line, shaded inside, opens down, (neither point is a solution)
Step-by-step explanation:
The graph is attached. Either the graph or the equation will tell you the vertex is (1, -2). Since the leading coefficient is negative, the parabola opens downward. Since the comparison is "y < ( )", shading is below the boundary line, so shading is inside the parabola.
The point (0, 0) is outside the parabola, so is not a solution. The point (2, -3) is on the (dashed) boundary line, so is not a solution. (The boundary line is dashed because points on it are not part of the solution set.)
__
The inequality is written in vertex form:
y < a(x -h)^2 +k . . . . . . . . has vertex (h, k)
The value of h in your inequality is 1, and the value of k is -2, so the vertex is (1, -2) as read from the inequality itself. (No graphing needed.)

HELP PLS What is the mtw?
Answer:
mTW = 230
Step-by-step explanation:
Remark
You have to assume that O is the center of the circle. Two sectors are marked as equal, so equate them to find x
Equation and Solution
5x + 5 = 4x - 20 Subtract 5 from both sides
5x + 5 - 5 = 4x+ 20 - 5 Combine
5x = 4x + 15 Subtract 4x from both sides.
5x-4x = 4x-4x + 15
x = 15
TOU = 5*15 + 5 = 80

2. Kachina is going to a concert that begins at 7:30 P.M. She
needs to arrive at the ticket window 15 minutes before
the concert to get her ticket. It takes Kachina 35 minutes
to ride to the concert, then 10 minutes to park the car. At
what time should Kachina leave for the concert?
Answer:
6:30 P.M.
Step-by-step explanation:
Since Kachina must do all these things before 7:30 P.M., we must find the sum of the times of the things she must do before the concert and subtract it from 7:30
The sum of the minutes is 60, which is 1 hour. Thus, Kachina should leave 1 hour before 7:30 which is 6:30 P.M.
A doctor wants to research if there is any difference in the birth weights of a mother's first child and second child. Suppose that data were collected for a random sample of 10 mothers with 2 children, where each difference is calculated by subtracting the weight of the first child from the weight of the second child. Assume that the weights are normally distributed. The doctor uses the alternative hypothesis Ha:μd≠0. Suppose the test statistic t is calculated as −1.101, which has 9 degrees of freedom. If the p-value is greater than 0.10 and the significance level is α=0.10, what conclusion can be made about the birth weights of a mother's first 2 children?
Answer:
There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance.
Step-by-step explanation:
When our p-value exceeds level of significance then we fail to reject our null hypothesis. In this scenario we are investigating if there exists significant difference in the birth weights of a mother's first child and second child and our null hypothesis is there exists no significant difference in the birth weights of a mother's first child and second child i.e.μd=0.
As we are given that p-value is greater than 10% level of significant so, we cannot reject our null hypothesis. Thus, the conclusion statement can be written as "There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance."
The graph below represents the relationship between the number of days a book is overdue and the library fine charged. A graph titled Library Fines. The horizontal axis shows days overdue and the vertical axis shows the fine (dollars). The line shows an increase to $10 at 19 days overdue, then constant. Christen returned an overdue book to the library. Her fine was the same as it would have been if she returned the book the previous day. Which of the answer choices below could be the number of days Christen’s book is overdue? 10 14 18 22
The number of days Christen's book is overdue could be 22 according to options given.
The graph which represents the relationship between the number of days a book is overdue and the library fine charged is attached below :
According to the graph, a constant relationship exists between the number of days a book is overdue and the library fine charged when the Number of days book is overdue is about 19 days and above such that the library fine charged stays the same at $10.
Since we are told that Christen's fine for returning the book is the same as the fine she would have paid if book was returned yesterday, then, the number of days Christen's book is overdue could be 20 days and above.
The only value above 20 from the options given is 22.
Hence, 22 is the valid answer.

what is the solution to x4 - 12x2+10>0
Answer:
(-√(6-√26) < x < √(6-√26)) ∪ (x < -√(6 +√26)) ∪ (√(6 +√26) < x)
Step-by-step explanation:
Using x^2 = z, the equation can be rewritten as ...
z^2 -12z +10 > 0
(z -6)^2 -26 > 0
|z -6| > √26
This resolves to two equations.
This one ...
x^2 -6 < -√26 . . . . substitute x^2 for z
|x| < √(6-√26) . . . . add 6, take the square root; use √a^2 = |a|
-√(6-√26) < x < √(6-√26)
__
and this one ...
x^2 -6 > √26
|x| > √(6 +√26)
x < -√(6 +√26) ∪ √(6 +√26) < x
