Answer:
4.086 or rounded to 4.1
Step-by-step explanation
Since we need to combine the amounts he ran on each day we need to add. We need to add normally and then add the decimal after the number 4. make sure to add km at the end to label your answer.
Quadratic Formula is (-b ±√(b²-4ac))/2a
With that being said:
y=2x²-5x-1 is in the correct form of ax²+bx+c
Now just plug in:
5±√(25-4(2 x-1))
5± √25+8
(5±√33)/2(2)
Answer is D

Answer:
4
Step-by-step explanation:
Area of a triangle = bh/2
B = 2h
16 = 2h × 2/2
h×2 = 16
2h = 16
* put a square root on both sides then u will get the answer which is
Height of the triangle = 4
Answer:
2(s-c)/ a^2 = v
Step-by-step explanation:
s = 1/2 a^2 v+c
Subtract c from each side
s -c = 1/2 a^2 v+c-c
s-c = 1/2 a^2 v
Multiply each side by 2
2(s-c) = 2* 1/2 a^2 v
2(s-c) = a^2 v
Divide each side by a^2
2(s-c)/ a^2 = a^2 v /a^2
2(s-c)/ a^2 = v
