Solve the quadratic equation below by completing the square. What are the solutions?
x^2 - 16x + 50 = 21
A. X= -8+sqrt 7
B. X= 8 + sqrt 7
C. X= 8 +sqrt 35
D. X= -8+sqrt 35
Answers
By completing squares we will see that the solutions are:
[tex]x =\pm \sqrt{35} + 8[/tex]
How to complete squares?
Here we have the quadratic equation:
[tex]x^2 - 16x + 50 = 21[/tex]
We can rewrite it as:
[tex]x^2 - 2*8*x + 50 - 21 = 0\\\\x^2 - 2*8*x + 29= 0[/tex]
Then we must have a 8² term to complete squares, then we need to add and subtract 35.
[tex]x^2 - 2*8*x + 29 +35 - 35= 0\\\\(x - 8)^2 - 35 = 0\\\\(x - 8)^2 = 35[/tex]
Now we can solve this:
[tex]x =\pm \sqrt{35} + 8[/tex]

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.
Cindy’s average speed for the entire run is ________
meters per minute. One kilometer is the same as 1,000 meters.
Answers
Answer:
286.1
Step-by-step explanation:
2 km = 2000 m
2 min = 250 m -> 125 m in 1 min
4 min = 1000 m -> 250 m in 1 min
1 min = 350 m -> 350 m in 1 min
3 min = 400 m (the rest) -> 133.33 m in 1 min
To get the average you add up all 3 and divide by 3
So: 125 + 250 + 350 + 133.33 = 858.33
858.33/3 = 286.11
So rounded its 286.1

Zachary purchased a computer for $1,900 on a payment plan. Two months after he purchased the computer, his balance was $900. What is an equation that models the balance y after x months
Answers
Answer:
[tex]y=-450x+1900[/tex]
Step-by-step explanation:
According to the problem, the payment plan is $1,900, so automatically our balance is $1,900. We are then told after two months, his balance was $900:
[tex]1900=900(2)[/tex]
To achieve the equation the problem is asking for we have to find how much Zachary would possibly be paying for one month. Divide the $900 into two months:
[tex]\frac{900}{2}[/tex]
[tex]=\frac{450}{1}[/tex]
Zachary pays [tex]450[/tex] a month, and we have to remember this is being subtracted from the initial balance. We can represent this as:
[tex]y=mx+b[/tex]
[tex]y=-450x+1900[/tex]

A gold mine has two elevators one for equipment and another for miners. The elevator for the miners descends 13 feet per second. The elevator for the miners descends 13 feet per second. One day the equipment elevator begins to descend. After 18 seconds the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 19 seconds? At that time, which elevator is deeper?
Answers
Answer:
The equipment elevator is positioned 481 feet closer and the miner equipment is positioned 342 feet closer relative to the surface. The equipment elevator is deeper.
Step-by-step explanation:
The rate that both elevators descend are the same according to the information given in the question.
After 18 seconds, the equipment elevator has descended 18 x 13 = 234 feet.
After another 19 seconds, the equipment elevator has descended for a total of 37 seconds which results in 481 feet and the miner elevator has descended for 19 seconds which gives us a descend of 342 feet.
So they are 481 and 342 feet closer relative to the surface and the equipment elevator is deeper since it has descended for a longer period of time.

can someone PLEASE help with this i don’t understand at all
Answers
therefore, those two added together would equal 180°
to solve for y, we just half to make an equation that does what we just planned
so: (2y + 50) + (5y - 17) = 180
now, just solve for y
7y + 33 = 180
7y = 147
y = 21
now, to solve for x, we’ll do the same thing (as those are also supplementary)
(7x - 248) + (x + 44) = 180
8x - 204 = 180
8x = 384
x = 48
now that we have x and y, just plug them into the expressions to get the degree values
top right: 2y + 50 = 2(21) + 50 = 42 + 50 = 92°
bottom right: 5y - 17 = 5(21) - 17 = 105 - 17 = 88°
top left: 7x - 248 = 7(48) - 248 = 336 - 248 = 88°
bottom left: x + 44 = 48 + 44 = 92°

Shana, who lives in Canada, and Pearl, who lives in Pennsylvania, were discussing the weather. Shana complained about the cold temperature of Negative 20 degrees Celsius. Pearl, who lives in Pennsylvania, mentioned that her temperature was the opposite of Shana's. Which is the correct way to represent "the opposite of Shana's temperature is equal to Pearl's"? Negative 20 = 20 Negative (negative 20) = negative 20 Negative (20) = negative 20 Negative (negative 20) = 20
Answers
Answer:
Negative (negative 20) = 20Step-by-step explanation:
Given Shana temperature = -20°C
°If Pearls temperature is opposite that of Shana's then Pearls temparature = -(-20) = 20°C
Hence the correct way to represent "the opposite of Shana's temperature is equal to Pearl's
Opposite of shana = -(-20°C)
Pearls temperature = +20°C
Since Opposite of shana = Pearls temperature, hence -(-20°C) = 20°C
Answer:
-(-20 = 20
Step-by-step explanation:
The "opposite" here means we take the negative of -20 C.
So we can write -(-20 which is equal to 20.
So the first option is correct, -(-20 = 20.
