During his science experiment, Yuri measured the temperature of a water sample as 24 degrees Celsius. To determine
the temperature in degrees Fahrenheit, he used the formula F-C+32, where F is the temperature in degrees
Fahrenheit and C is the temperature in degrees Celsius. Which is a correct step in the process Yuri should take to
convert the temperature? Check all that apply.
Substitute 24 for
Substitute 24 for C.

Add 32 to C before multiplying by
Multiply the value of C by 5 before adding 32.
24°C is 75.2°F.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
