Answer:
see explanation
Step-by-step explanation:
HF is a perpendicular bisector of Δ EGH
Then Δ EGH is an isosceles triangle with 2 congruent sides GH and EH , so
GH = EH
3x - 8 = 2x ( subtract 2x from both sides )
x - 8 = 0 ( add 8 to both sides )
x = 8
Then
GH = 3x - 8 = 3(8) - 8 = 24 - 8 = 16
Answer:
From diagram, FG = EF
Solving fo HF and FG by Pythagorean Theorem
HF² = (3x -8)² -FG²
HF² = (2x)² -FG²
We can eliminate HF² and FG² from BOTH equations because they cancel out.
The 2 equations become (3x -8)² = (2x)²
9x² -48x +64 = 4x²
5x² -48x +64 = 0
Using Quadratic Formula
X1 = 8
X2 = 1.6

Step-by-step explanation:
Why is Equation #2 greater than Equation #1?
This is because the equations are the same, except that the second equation is shifted up by eight units. This means that its value is always going to be eight units greater.
This same reasoning applies to Equations 3&4 and 5&6.
Why is Equation #3 greater than Equation #2?
This is because a certain value multiplied by three (even with eight added) will soon be overtaken by that value squared. For example, let's make x= 5
3(5) + 8 = 23
(5)^2 = 25
As you can see, the equation x^2 is already greater in value than 3x + 8.
Why is Equation #5 greater than Equation #4?
This is because a certain value squared will soon be overtaken by 4 to the power of that value. For example, let's make x= 2
(2)^2 + 6= 10
4^2 = 16
As you can see, the equation 4^x is already greater in value than x^2 + 6.
Hope this helps! :)

A fair coin is flipped 10 times. What is the probability that the first flip comes up heads or exactly five flips come up heads (or both)
Answers
The probability for the given event is P = 0.75
How to get the probability?The probability for flipping both sides of the coin is exactly the same one because we have an even coin.
The probability of getting the first flip heads up is just 0.5, as we can expect.
The probability that exactly 5 flips come heads up is:
P = C(10, 5)*(0.5)^10 = (0.5)^10*(10*9*8*7*6)/(5*4*3*2*1) = 0.25
Then, adding these two, the total probability is:
p = 0.5 + 0.25 = 0.75

Which statements are true about the graph of function f?
F(x)=1n x
Please I really need help!!
Answers
Answer:
D: See attached file and explanation
Step-by-step explanation:
Notice how the function has a vertical asymptote at x=0, indicating that 0 is the minimum of the domain which is not included.
The end behavior of the function would be as x approaches infinity, y approaches infinity, which means that the correct domain would be {x|0<x<∞}.
Additionally, the function crosses the x-axis at (1,0) so that would be the x-intercept.
There is no y-intercept because x=0 is undefined for the function as we already described earlier with it being the line of the vertical asymptote.
Therefore, the correct answer is D. See the graph for reference.

The coordinate of point R in quadrilateral RUST are (4,2).
R is dilated by a scale factor of 2, centered at the origin, followed by the translation (x, y) + (x - 1, y - 1).
To find:
The coordinates of R' after dilation and translation.
Solution:
If a figure is dilated by a scale factor of 2, centered at the origin, then
(x, y) ⇒ ( 2x, 2y )
We value R(4,2).
R(4,2) ⇒ R_1( 8,4)
The rule of translation is:
(x, y) + (x - 1, y - 1).
Using this rule, we get
R_1( 8,4) ⇒ R' ( 7,3)
Therefore, the coordinates of point R' are (7, 3) and the correct option is B.

In a survey of 554 U.S. adults, it is found that 360 favor a ban on stem cell research. Set up the null and the alternative hypotheses to test whether there is sufficient evidence that over 61% favor a ban on stem cell research. If alpha is set to 3.0%, should the null hypothesis be rejected
Answers
Answer:
The null hypothesis will be rejected
Step-by-step explanation:
The null hypothesis is that people who favour ban on stem cell research is less than or equal to 0.61
The alternate hypothesis is that people who favour ban on stem cell research is greater than 0.61
Proportion of population = 0.61
Total events = 360
Sample size = 554
Sample proportion = 360/554 = 0.649
As per test statistics –
Z = (p-p0)/sqrt {(p0 (1-p0))/n} = (0.649 -0.61)/ {(0.61 (1-0.61))/554}
= 0.039/0.021
= 1.857
P (Z<1.857) = 1- P (Z<1.857) = 1-0.9664 = 0.0336
So alpha value is 0.064.
Thus, we will reject the null hypothesis

What is mid point theorem?The mid point theorem states that in a triangle the line segment joining the mid point of two sides is always parallel and equal to half of the length of the third side.
As per the given figure the data is as follows,
The line segment of length 6x + 7 is parallel to the side of a triangle of length 19x - 28 such that it divides other two sides equally.
Apply mid point theorem to obtain,
6x + 7 = 1/2(19x - 28)
=> 19x/2 - 6x = 14 - 7
=> 7x/2 = 7
=> x = 2
Hence, the value of x for the given triangle is 2.
