The equation has 0 real solutions.
If an equation has a negative discriminant, than there are no real solutions. We know this because the quadratic formula requires you to take the square root of the discriminant and therefore you would have all imaginary numbers.
Answer=4000ft
There are 3280.84 feet in 1 kilometer
1km=3280.84ft
4000ft >3280.84 ft
therefore, 4000ft is longer than 1 km
4000ft>1km
Answer:
I don't know if you have heard of this question but if you
The area of a square is s•s.
A= 6.25•6.25
A= 39.0625
Rounded= 39.06 square feet
(I'm assuming rounding to the significant digits means rounding to the hundredths since 6.25 is rounded to the hundredths.)
Answer:
1. a) the square root of 20
2. d) the square root of 52
Explanation:
we can use the formula of pythagoras' theorem, which is a² + b² = c² (with c being the hypotenuse of a right-angled triangle while a and b are its other two sides), to solve these questions.
for the first question, we can place the given values into the equation to get 4² + b² = 6², with b being the unknown here. b is thus equivalent to 6² - 4², or <u>√20</u>.
for the second question, we can get 4² + 6² = c², which is the unknown value in this question. it would be <u>√52</u>.
i hope this helps! :D
