because the roots are the x values of where the function crosses the x axis
so thats at -2 and 3
and product is multiplication
so -2×3= -6

Answers
Answer:
A.) x / 3 = 12 ----> x = 12(3) ----> x = 36
B.) 2x + 3 = 20 ----> 2x = 17 ----> x = 17/2
C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2
D.) -4x = -24 ----> x = -24/-4 ----> x = 6
E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9
F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8

[tex](\frac{-b}{2a},\frac{4ac-b^2}{4a})\\(\frac{-12}{2(-3)}),(\frac{4(-3)(-5)-(12)^2}{4(-3)})\\(\frac{-12}{-6}),(\frac{60-144}{-12})\\(2,\frac{-84}{-12})\\(2,7)[/tex]
The vertex is at (2,7)
( 2 ) Find by using a derivative (Calculus)
You can also find a vertex by using a calculus. Using a derivative
[tex]y'=-3x^2+12x-5\\y'=-6x+12\\\\[/tex]
Then substitute y' = 0 to get a vertex.
[tex]y'=-6x+12\\0=-6x+12\\-12=-6x\\2=x[/tex]
Then substitute x = 2 in the equation of y = -3x²+12x-5
[tex]y=-3x^2+12x-5\\y=-3(2)^2+12(2)-5\\y=-3(4)+24-5\\y=-12+24-5\\y=-17+24\\y=7[/tex]
x = 2 and y = 7, therefore. The vertex is (2,7)

Sea ice is frozen ocean water, which freezes at a temperture of about -1.8 degress celsius. What is the temperture in fahrenheit use the formula F=(c) (9/5)+32
Answers
Answer:
28.76 °F
Step-by-step explanation:
The temperture of sea ice frozen ocean water is about -1.8 °C .
We are to convert to a temperture in fahrenheit using the formula F=(c) (9/5)+32
°C = -1.8°C
°F=(c) (9/5)+32
= [(-1.8°C × 9/5) + 32]°F
= [-16.2/5 + 32]°F
= [-3.24 + 32]°F
= 28.76°F

HELP At the end of a snow storm, Eli saw there was a lot of snow on his front lawn. The
temperature increased and the snow began to melt at a steady rate. The depth of
snow on Eli's lawn, in inches, can be modeled by the equation S = 16 - t, where t
is the time, in hours, after the snow stopped falling. What is the y-intercept of the
equation and what is its interpretation in the context of the problem?
The y-intercept of the function is
which represents
Answers
Answer:
The y-intercept is 16, which represents the original depth of snow on the lawn
Step-by-step explanation:
t is the time in hours where the snow melted, so 16 was the original amount of snow on the ground before it melted over time.
The y-intercept is 16 inches. Then the y-intercept represents the height of the snow initially.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Eli noticed a lot of snow on his front lawn towards the conclusion of a snowstorm. As the weather rose, the snow began to melt at a steady pace. The depth of snow on Eli's lawn in inches may be calculated using the equation S = 16 - t, where t is the time after the snow ceased falling in hours.
Compare the equation with the standard equation, then we have
c = 16
The y-intercept represents the height of the snow initially.
