On Tuesday the temperature is 1 ºC. By Wednesday it has dropped to –2 ºC. The temperature drops by twice as much from Wednesday

Finger [1]

Answer: $-8^{\circ}C$

Step-by-step explanation:

Given

The temperature on Tuesday is $1^{\circ}C$

Temperature drops to $-2^{\circ}C$ on Wednesday

Net drop in temperature $1-(-2)=3^{\circ}C$

The temperature drops twice from Wednesday to Thursday

$\Delta T=2\times 3=6^{\circ}C$

Temperature on Thursday

$\Rightarrow -2-6=-8^{\circ}C$

Answer: second option

Step-by-step explanation:

The standard form of a quadratic equation is:

$ax^2+bx+c=0$

Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:

$2x^2+5x-1=0$

Given the quadratic equation above, to find the value of $b^2-4ac$ you must substitute:

a=2; b=5 and c=-1 into $b^2-4ac$

Thenrefore, you obtain the following result:

$5^2-4(2)(-1)=33$
