In the picture, ▲ABC is an equilateral triangle. Segment BD is the perpendicular bisector of segment AC. Find the length of BD. Represent your answer in simplest radical form.
Answers
Answer:
Step-by-step explanation:
since it is an equilateral triangle all sides =8
bit bisector BD AC into equal halfs.so AD=4
bow to find BD use pythagoras theorem
H^2=P^2+B^2
AB^2=AD^2+BD^2
8^2=4^2+BD^2
64-16=BD^2

Let A represent the amount of money she will have on July 30.
Answers
Answer:
A = $800 -$350 -30w-30f-2c
Step-by-step explanation:
Given
Total sum of money in account of Marissa on July 1 - $800
Sum of money earned per week = $w
Money spend of following -
gasoline - $g per day
Food - $f per day
New clothes every two week - $c
Rent per month - $350
Total sum of money in account of Marissa on July 1
A = $800 -$350 -30w-30f-2c

Answers
Answer:
Ethan can make 48 possible combinations.
Step-by-step explanation:
Given that Ethan has packed 6 shirts, 4 pairs of pants and 2 pairs of shoes for vacation, to determine how many possible outfit combinations does Ethan have for his trip the following calculation must be performed:
Shirts x pants x shoes = Number of combinations
6 x 4 x 2 = X
24 x 2 = X
48 = X
Therefore, Ethan can make 48 possible combinations.

We add all the numbers together, and all the variables
4x/6-2.5=0
We multiply all the terms by the denominator
4x-(2.5)*6=0
We add all the numbers together, and all the variables
4x-15=0
We move all terms containing x to the left, all other terms to the right
4x=15

The question is asking about the hypotenuse L. You can get that by using the Pythagorean Theorem( a^2+B^2=C^2). You can get the bottom length of the triangle by dividing 8 by 2, because the triangle is made from the top point of the pyramid. You can there do 5^2+4^2, which is 41.

Radioactive technetium-99m is often used in diagnostic medicine because it has relatively short half-life but lasts long enough to get the needed testing done on the patient. If its half-life is 6 hours, how much of the radioactive material from a 2.5ml injection will be in the body in 30 hours? Write your answer rounded to nearest hundredth.
Answers
Using an exponential function, it is found that 0.08 ml of the will be in the body in 30 hours.
The amount of a decaying substance is modeled by an exponential function in the following format:
[tex]A(t) = A(0)e^{-kt}[/tex]
In which:
A(0) is the initial amount.k is the decay rate, as a decimal.In this problem, the half-life is 6 hours, which means that [tex]A(6) = 0.5A(0)[/tex], and this is used to find k.
[tex]A(t) = A(0)e^{-kt}[/tex]
[tex]0.5A(0) = A(0)e^{-6k}[/tex]
[tex]e^{-6k} = 0.5[/tex]
[tex]\ln{e^{-6k}} = \ln{0.5}[/tex]
[tex]-6k = \ln{0.5}[/tex]
[tex]k = -\frac{\ln{0.5}}{6}[/tex]
[tex]k = 0.11552453009[/tex]
Hence:
[tex]A(t) = A(0)e^{-0.11552453009t}[/tex]
2.5 ml injection, hence [tex]A(0) = 2.5[/tex]
After 30 hours, we have to find A(30), hence:
[tex]A(t) = 2.5e^{-0.11552453009t}[/tex]
[tex]A(30) = 2.5e^{-0.11552453009(30)}[/tex]
[tex]A(30) = 0.08[/tex]
0.08 ml of the will be in the body in 30 hours.

You Have Tiangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9) After a 90 Degree Counterclockwise rotation, what is the new coordinate of Z'?
Answers
Answer:
Z'(9, - 1)
Step-by-step explanation:
For a 90 degree counterclockwise rotation about the origin,
The original coordinates of point P (x,y) will now be positioned as P' (-y,x).
Hence, given :
Triangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9)
The new position of Z denoted as Z' will be :

Consider functions f, g, and h. (SEE PICTURE ATTACHED)
Which expression defines function h?
Answers
Answer:
the answer is C
you have to use horner Division because its so easily to use
just search horner divission in polonium and you will find it
The expression f(x)/g(x) defines function h(x)=3x^2+12x.The answer is C.
We have given that,
[tex]f(x)=3x^2+9x^2-12x[/tex]
[tex]g(x)=x-1[/tex]
and, [tex]h(x)=3x^2+12x[/tex]
What is the division of the function?Suppose f(x) and g(x) are function,
[tex](\frac{f}{g}) (x)=\frac{f(x)}{g(x)}[/tex]
So we have given function us
[tex]f(x)=3x^2+9x^2-12x[/tex]
[tex]g(x)=x-1[/tex]
We have divide f(x) by g(x)
[tex]=\frac{3x^3+9x^2-12x}{x-1}[/tex]
[tex]=3x\left(x+4\right)[/tex]
[tex]=3x^2+12x[/tex]
Therefore we get the expression f(x)/g(x) defines function h.
