help plz solve these equations by completing the square
x square + 12x =1
Answers
Answer:
x = - 6 ± [tex]\sqrt{37}[/tex]
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± [tex]\sqrt{37}[/tex] ( subtract 6 from both sides )
x = - 6 ± [tex]\sqrt{37}[/tex] ← exact solutions

oil is leaking out of a tank. the depth of oil in the tank for 60 seconds is shown below. use the graph to work out the rate of decrease of depth, in cm/s, at 10 seconds. you must show your working.
Answers
Answer:
2.24
Step-by-step explanation:
The rate of decrease at 10 seconds is - 0.642.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
From the graph, we conclude that it is an exponentially decaying function.
At t = 10, depth = 60 and at t = 0 depth = 112
(as every box represents 4 units).
So, the rate of decrease can be obtained by,
112 = 60.e^(-10k).
e^(-10k) = 1.86.
lne^(-10k) = ln1.86.
- 10k = 6.42.
k = - 0.642.
The rate of decrease at 10 seconds is - 0.642.

Kristen is making accessories for the soccer team. She uses 595.56 inches of fabric on headbands for 39 players and 3 coaches. She also uses 343.59 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answers
Answer:
22.99 inches
Step-by-step explanation:
According to problem, given data are as follows:
Fabric used for headband = 595.56 inches
Number of headbands made = 39 + 3 = 42
So, Fabric used per headband = 595.56 ÷ 42 = 14.18 inches per headband
Similarly, Fabric used for wristband = 343.59 inches
Number of wristbands made = 39
So, Fabric used per wristband = 343.59 ÷ 39 = 8.81 inches per wristband
So, Fabric used for each player = 14.18 inches + 8.81 inches
= 22.99 inches

How many integers are there that consist of four digits (from 1000 to 9999) where the first digit is a 5 or an 8 and the third digit is not 5 or 8
Answers
Answer:
1600 integers
Step-by-step explanation:
Since we have a four digit number, there are four digit placements.
For the first digit, since there can either be a 5 or an 8, we have the arrangement as ²P₁ = 2 ways.
For the second digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
For the third digit, since it neither be a 5 or an 8, we have two less digit from the total of ten digits which is 10 - 2 = 8. So, the number of ways of arranging that is ⁸P₁ = 8.
For the last digit, we have ten numbers to choose from, so we have ¹⁰P₁ = 10.
So, the number of integers that can be formed are 2 × 10 × 8 × 10 = 20 × 80 = 1600 integers
