Answer:

x=-13

Step-by-step explanation:

If we have a quadratic function and the vertex is

(h,k) then our axis of symmetry is x=h.

So here our axis of symmetry is x=-13

Answer:

148-13=135

4x+13= - 3.25

6x+2 = - 0.33

Step-by-step explanation:

1) SIMPLE SUBTRACTION

---------

4x+13=0

4x= - 13

x= -13/4

x= - 3.25

6x+2 = 0

6x= -2

x= -2/6

x = -0.33

A man weighing 800 N is hanging from a 2 mm diameter titanium wire with a cross-section of 3 x 10^-6 m^2. Will the wire break?

DENIUS [597]

Answer:

Since stress is greater than ultimate strength, the wire will break.

Step-by-step explanation:

The titanium wire is experimenting an axial load. Ultimate strength equals $2.20\times 10^{8}\,Pa$ . The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress ( $\sigma$ ), measured in pascals, in the wire with circular cross-section is:
