If using the method of completing the square to solve the quadratic equation
x2 + 7x – 27 = 0, which number would have to be added to "complete the
square"?
Answers
To determine the constant that makes the expression (x² + kx) a perfect square,
Take the coefficient of the second term which is k and ÷2
In this case, it is (7/2)²
At the end it looks like
x² + 7x + (7/2)² = 27 + 49/4
(x + 7/2)² = 157/4
The number is added is 7/2² or 49/4.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
x² + 7x – 27 = 0.
Now, we have to half the coefficient of x and then add and subtract the square of half the coefficient of x
So, x² + 7x – 27 +7/2² - 7/2² = 0.
( x+ 7/2)² – 27- 49/4 = 0.
( x+ 7/2)² = 157/4
Hence, the number is added is 7/2² or 49/4.

The peak at transfer camera is 10 8.7 he travels 7.5 metre in car and took a break how much more he has to travel to reach the top of the mountain
Answers
The question is not well formatted
Let's assume that the peak value Given is 108.7m
However, If that is not the actual value, then you can just follow the steps with the actual value to obtain your answer.
Answer:
101.2 meters
Step-by-step explanation:
Taking the peak Given as 108.7 m
The distance traveled by car = 7. 5 meters
The distance left to reach the top of the mountain :
108.7 meters - 7.5 meters
= 101.2 meters

The appropriate answer is "10,455.29856".
Step-by-step explanation:
According to the question,
The time will be:
⇒ t = [tex]2022-2017[/tex]
⇒ = [tex]5[/tex]
On applying formula, we get
⇒ [tex]f(t)=25000(1-.16)^t[/tex]
On substituting the value of "t", we get
⇒ [tex]f(5)=25000(1-.16)^5[/tex]
⇒ [tex]=25000(0.84)^5[/tex]
On solving the power, we get

URGENT: Create a linear system whose ONLY SOLUTION is (3,13) . I just need the equations for f(x)=? , G(x)=? To get (3,13). ASAP!!!!! PLZZZ
Answers
The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13
The two lines can be anything as long as they give this solution
For example, if you wrote x + y = 16 (you know their values already)
Then write another y - x = 10
From here you have your equations, turn them into the f(x) form.
x + y = 16 can be turned into y = 16 - x which is f(x)=16-x
y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x

V(t)=500⋅(1.8)t
Complete the following sentence about the daily percent change in the views of the video.
Answers
Answer: 80% views are added
Step-by-step explanation:
The required daily percent change in the views of the video is 50%.
Nina uploaded a funny video on her website, the relationship between the elapsed time t, and number of views. V(t) is V(t)=500⋅(1.8)t.
What is rate of change?
Rate of change is defined as the change in value with rest to the time is called rate of change.
Here,
V(t)=500⋅(1.8)t
The slope of the given relationship will describe the the daily percent change in the views of the video i.e.
m = 500*1.8
m = 900
since the rate of increase in views in each day is by 900.
Now the percentage change per day.
= 900/1800 x 100
= 50 %
Thus, the required daily percent change in the views of the video is 50%.
