Step-by-step explanation:
just think a little bit.
the balloon goes down 140 feet per minute.
how many feet will it have descended after 2 minutes ?
twice as much, right ?
after 5 minutes ? 8 minutes ? 10 minutes ? 15 minutes ?
we have to multiply.
simply because we need to maintain the value of the ratio feet/minute at all times.
so, when we multiply the "minute" part (by saying e.g. 5 minutes), we need to multiply the "feet" part with the same factor to keep the overall ratio the same. and then the resulting "feet" part gives us the answer.
so, after 2 minutes that means
140 ft / 1 min × 2/2 = 280 ft / 2 min
=> it descended 280 ft.
so, it's height is then at that moment
2520 - 280 = 2240 ft
5 minutes
140 ft / 1 min × 5/5 = 700 ft / 5 min
=> it descended 700 ft.
so, it's height is then at that moment
2520 - 700 = 1820 ft
and so on.
we see, that the general equation to determine the actual height (h) of the balloon depending on the passed number of minutes (m) is then
h = 2520 - 140m
so
2520 - 140×2 = 2240 ft
2520 - 140×5 = 1820 ft
2520 - 140×8 = 1400 ft
2520 - 140×10 = 1120 ft
2520 - 140×15 = 420 ft

A.) an = 2/9 • 3^n
B.) an = 3(2/9)^n-1

Answer:

The iterative rule for this geometric sequence is [tex]a_{n} =\frac{2}{9} *3^{n-1}[/tex]
What is geometric sequence?A unique kind of sequence is a geometric sequence. Every term in the series (aside from the first term) is multiplied by a fixed amount to determine the following term. In other words, we multiply the current phrase in the geometric sequence by a constant term (called the common ratio), Divide the current term in the geometric sequence by the same common ratio to discover the previous term in the geometric sequence. Here is an illustration of a geometric sequence with a common ratio of 2, which is 3, 6, 12, 24, and so on. A geometric sequence's common ratio can be either negative or positive, but it cannot be zero.Given that we are aware that a geometric series has an explicit formula in form[tex]a_{n} =(a_{1} )*r^{n-1}[/tex]where, [tex]a_{n}[/tex]=nth term of geometric sequence[tex]a_{1}[/tex]= 1st term of geometric sequencer=common ratioWe can see that our geometric sequence's first term is. By dividing any number by the number that comes before it in the sequence, let's find the common ratio of our supplied sequence.Since 2 comes before 6 in the given geometric sequence, let's divide 6 by 2.r= 6/3 = 3The common ratio is three, as can be seen.When we use the explicit geometric sequence formula with our values, we will obtain,[tex]a_{n} =\frac{2}{9} *3^{n-1}[/tex]Therefore, The iterative rule for this geometric sequence is [tex]a_{n} =\frac{2}{9} *3^{n-1}[/tex]

In the figure below, m
110°, m
68°, and KN bisects LKM. Find JKN.
Answer:
m<JKN=76º
Step-by-step explanation:
since the angle bisects just divide 68 by 2
m<LKN=34º
then since JKM is the total of all angle measurements
110-68=42
so m<JKL=42º
JKL+LKN=JKN
42+34=76
to check just add the measurements and makes sure that they make 110
so 76+34=110
The value of an angle ∠JKN will be 76 degrees.
What is an angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. In geometry, the ray, line, or segment that divides a given angle into two equal pieces is known as the angle bisector.
Given that In the figure, m 110°, m 68°, and KN bisects LKM.
Since the angle bisects just divide 68 by 2
∠LKN=34º
Then since JKM is the total of all angle measurements
110-68=42
∠JKL=42º
JKL+LKN=JKN
42+34=76 degrees
Therefore, the value of an angle ∠JKN will be 76 degrees.

8. (1.2) Sketch the information given then find BD. Points A.
collinear and in that order. CD = -254 + 8x, AC = 92, BD = x + 113,
and AB = 13x - 527,
First draw a straight line and plot the four points A,B,C,D on that line. It doesn't matter where you plot the points as long as they are in order and none overlap.
We're given AD = x+203. We also know that BD = x+127. Since AB + BD = AD (segment addition postulate) we can determine the length of AB
AB + BD = AD
AB + BD-BD = AD-BD Subtract BD from both sides.
AB = AD-BD
AB = (x+203)-(x+127)
AB = x+203-x-127
AB = 76
The length of BC is also 76 (given). So,
AB+BC = 76+76 = 152
this is equal to the length of AC because AB+BC = AC
So, AC = 152 units
Final Answer: 152 units

Explain how to graph the given piecewise-defined function. Be sure to specify the type of endpoint each piece of the function will have and why. f(x)= 3, x + 3, X < 2 25 x < 4 4 – 2x, x 2 4
You would graph the equation f(x) = –x + 3 for input values less than 2. There would be an open circle at the point (2, 1) since the domain for the first piece does not include 2. You would then graph a horizontal line at f(x) = 3 for input values between 2 and 4. There would be a closed circle at (2, 3) and an open circle at (4, 3). Last, you would graph f(x) = 4 – 2x for input values greater than or equal to 4. There would be a closed circle at the point (4, –4) since 4 is in the domain of the third piece.
