An airplane ascended into the sky to a steady altitude of 35000 feet. The same plane descended to a steady altitude of 32000 feet. How many feet did the airplane descend
Answer:
3000 feets
Step-by-step explanation:
Given that :
Initial Ascent to steady altitude = 35,000 feets
Descent to steady altitude = 32,000 feets
Number of feets the plane descend :
(Initial ascent to steady altitude - descent to steady altitude)
(35000 - 32000) feets = 3,000 feets

Solve the equation for all real solutions in simplest form.
z^2 - 12z +9= -3
Answer:
Solving the equation for all real solutions in simplest form.
[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]
Step-by-step explanation:
We need to solve the equation for all real solutions in simplest form.
[tex]z^2 - 12z +9= -3[/tex]
First simplifying the equation:
[tex]z^2 - 12z +9+3= -3+3\\z^2 - 12z +12= 0[/tex]
Now, we can solve the equation using quadratic formula:
[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
we have a = 1, b=-12 and c=12
Putting values in formula and finding values of x
[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\z=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(12)}}{2(1)}\\z=\frac{12\pm\sqrt{144-48}}{2}\\z=\frac{12\pm\sqrt{96}}{2}\\z=\frac{12\pm9.8}{2}\\z=\frac{12+9.8}{2}\:or\:z=\frac{12-9.8}{2}\\z=10.9\:or\:z=1.1[/tex]
So, we get value of z: z=10.9 or z=1.1
Solving the equation for all real solutions in simplest form.
[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]

Answer:
The value of x is 5.8
Step-by-step explanation:
Here. we want to find the value of x
To do this, we need the appropriate trigonometric identity
As we can see 10 is the opposite as it faces the side given
x is the adjacent
The trigonometric identity relating opposite and adjacent is tan . Tan is the ratio of the opposite to the adjacent
Thus, mathematically;
Tan 60 = 10/x
x = 10/tan 60
x = 5.8

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 790 meters , and plane B was at an altitude of 1142 meters. Plane A losing altitude at 14 meters per second, and Plane B is losing altitude at 22 meters per second
Answer:
[tex]x=4.375[/tex]
Step-by-step explanation
From the question we are told
Plane A starts at altitude 790
Plane B starts at altitude 1142
Plane A losing altitude at 14 meters per second
Plane B is losing altitude at 22 meters per second
Generally the altitude of both plane is given by
Plane A= [tex]790-14x[/tex]
Plane B=[tex]1142-22x[/tex]
Therefore when they exist in the same altitude
[tex]790-14x[/tex] =[tex]1142-22x[/tex]
[tex]-350=-8x[/tex]
[tex]\frac{-350}{-8} =x[/tex]
Therefore
[tex]x=4.375[/tex]

is this mapping a function or not a function ¿ i’ll mark brainlist
Answer:
Not a function
Step-by-step explanation:
If it is a function, every input has only one output. Meaning if we graph it, it will pass the vertical line test.
If you want to think about it in x and y, all values of x can only correspond to one value of y.
In this case, we can see that the x-value 6 has 2 corresponding y-values (5 and 10), therefore, this mapping is not a function.
1. What is the initial balance in the account?
2. Is the account growing by the same number of dollars each year? Explain how you know.
3. A second investment account starts with $2,000 and grows by $150 each year.
4. How does the growth of balances in the two account balances compare?
Answer:
The opening balance is the amount of funds in a company's account at the beginning of a new financial period. It is the first entry in the accounts, either when a company is first starting up its accounts or after a year-end.
The initial balance in the account was approximately $4215.
How to find the initial balance in the account?The formula represents the relationship between the initial balance, the interest rate, the compounding period, and the time period.
To determine the initial balance in the account, we can use the formula for compound interest:
A = P(1 + r)ⁿ
where:
A = the ending balance
P = the initial balance
r = the annual interest rate as a decimal (5% = 0.05)
t = the number of years
Substituting the given values, we get:
[tex]5000 = P(1 + 0.05)^{(3.5)}[/tex]
[tex]5000 = P(1.05)^{(3.5)}[/tex]
Dividing both sides by [tex](1.05)^{(3.5)}[/tex], we get:
[tex]P = 5000/(1.05)^{(3.5)}[/tex]
Using a calculator, we get:
P ≈ $4215
Therefore, the initial balance in the account was approximately $4215.

HELP HELP PLS!!! 9th Grade Math!!! WILL MARK BRAINLIST!!!
Answer:
x=9
Step-by-step explanation:
These angles are equal to each other because they are alternate exterior angles. Thus, we can solve the for the value of x by creating the equation
6x+5=7x-4
From here, we solve it like a normal algebraic equation, isolating the variables and making sure it is on the same side of the other. From there we subtract 7x from both sides, and subtract 5 from both sides, leaving -x = -4-5. Summing up -4-5, we get -x=-9. Now we make them positive on both sides, leaving the answer that x = 9
Michael drove his car for 150 minutes at a constant speed of 75 miles per hour and then for another 2 hours at a constant speed of 81 miles per hour.
How far did Michael drive? Show or explain how you got your answer.?
Answer:
he traveled a total of 349.5 miles.
Step-by-step explanation:
*First we convert the 150 minutes to hours, that is :
[tex]h=\frac{1.150}{60} \\h=2.5[/tex]
Now we determine the distance Michael traversed during those 2.5 hours:
[tex]d_{1} =2.5.75 \\d_{1} =187.5\\[/tex]
He transversed 187.5 miles.
We also determine the distance he tranversed the two remaining hours:
[tex]d_{2} =2.81 \\d_{2} =162[/tex]
He also traveled 162 miles
Finally we add both traversed distances:
[tex]d_{t}=187.5+162 \\d_{t} =349.5\\[/tex]
So , he traveled a total of 349.5 miles.
