Evaluate v(x)=12-2x-5.8 when x =-2,0, and 5

Mathematics
1 answer:
Nata [24]3 years ago
5 0

Answer:

Step-by-step explanation:

<u>Is this equation written correctly?:</u>

<u></u>

v(x)=12-2x-5.8

v(x) = -2x+6.2

v(-2) = -2(-2)+6.2

<u>v(-2) = 2.3</u>

v(0) = -2(0)+6.2

<u>v(0) = 6.2</u>

v(-5) = -2(-5)+6.2

v(-5) = 10+6.2

v(-5) = 16.2

When looking at the graph of a 5th degree function, how can you determine if all of the zeros of the function are real?
Finger [1]

Answer:

If it cuts x-axis 5 times.

Step-by-step explanation:

When we look at the graph of a function we can see its real roots by looking at its graph

The intersecting points that is the number of times a line cutting x-axis will be the real root of the function

So, by looking at the 5th degree function the number of time that function cuts x-axis will be the number of real roots.

So, if we need to say all the zeroes or roots of the function are real means it will cut the x-axis 5 times.

Because a function will have the root equal to its degree.

A circular labyrinth has a circumference of 75 feet what is the distance from the outside edge of the labyrinth in to it center
Bas_tet [7]
The distance from the outside edge of a circle to its centre is given by its radius. The circumference of a circle is given by 2πr, thus if we know that this is equal to 75 feet and using π = 3.14, we get:

75 = 2*3.14*r
r = 11.942
Thus r = 12 ft (to the nearest foot)

Find the sum and the product of the roots of the equation:<br><br> x^2−37x+27=0
lawyer [7]

Answer:

Sum of the Roots = 37

Product of the Roots = 27

Step-by-step explanation:

Here, the given expression is  x^{2}  - 37x + 27 = 0

Now the general Quadratic Equation is of the form:

ax^{2}  + bx + c = 0

Here, Sum of the Roots = -(\frac{b}{a} )

and the Product of the Roots =  (\frac{c}{a} )

So, comparing the general equation with the given equation, we get:

a = 1, b = -37 and c = 27

So, Sum of the Roots = -(\frac{-37}{1} )  =  37

and the Product of the Roots =  (\frac{27}{1} ) = 27
