The solution to the quadratic equation 2x² - 4x - 3 = 0 is x = 1 ± √2.5
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Solving the polynomial using completing the square:
2x² - 4x - 3 = 0
First divide through by 2:
x² - 2x - 3/2 = 0
add 3/2 to both sides:
x² - 2x - 3/2 + 3/2 = 0 + 3/2
x² - 2x = 3/2
add the square of half the coefficient x to both sides:
x² - 2x + 1 = 3/2 + 1
(x - 1)² = 2.5
taking square root:
x - 1 = ±√2.5
x = 1 ± √2.5
The solution to the quadratic equation 2x² - 4x - 3 = 0 is x = 1 ± √2.5

Answer:
Rate of change 
C per meter.
Step-by-step explanation:
Given,
Then,
Change of temperature at the point say, 
along the direction say, 
is,
![\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}](https://tex.z-dn.net/?f=%5CBig%5BuT_%7Bx_2%7D%2BvT_%7By_2%7D%2BwT_%7Bz_2%7D%5CBig%5D_%7B%28x%2Cy%2Cz%29%7D)
=
Hence the rate of change of temperature is C per meter.
Answer:
6 1/2
Step-by-step explanation:
1 1/2 times 3 for 3 days = 4 1/2 + 2 = 6 1/2 So, the answer wold be 6 1/2 hours or 6.5 hours.
A)
sinA = 8√3 / 16 = √3 / 2
answer is B
√3 / 2
B) It's 30 60 90 right triangle
so <B is 30
answer is A
m<B = 30
