4 0

Step-by-step explanation:

x2 + bx +5 = 0,

where a,b and c are rational numbers.

Also it is given that the quadratic has 2 distinct zeros and one of it's zero is irrational.

We know that if it has a one irrational zero, the conjugated couple of the one zero is also a null with the same polynomial balance for a polynomial equation with rational coefficients." Therefore, in this case it is a quadratic equation, one is null and irrational; thus, the other zero is irrational.

A rental car company charges $30 a day plus $0.05 a mile. Which expression could be used to find the cost of renting a car for m

Gnoma [55]

Answer:

C

Step-by-step explanation:

Since the company earns $0.05 for every mile, we would multiply m by 0.05. We also add it with 30 since it is a base charge. This makes it C

It can't be A or B since that would mean the company earns $30.05 for every mile.

It can't be D since that would mean the company earns $30 for every mile with a base charge of $0.05.

Please Help me it’s geometry

mote1985 [20]

Answer:

Option C.

Step-by-step explanation:

Given: In $\Delta OPQ,m\angle O=107^{\circ},m\angle P=28^{\circ}$ .

In $\Delta OPQ$ ,

$m\angle O+m\angle P+m\angle Q=180^{\circ}$ (Angle sum property)

$107^{\circ}+28^{\circ}+m\angle Q=180^{\circ}$

$135^{\circ}+m\angle Q=180^{\circ}$

$m\angle Q=180^{\circ}-135^{\circ}$

$m\angle Q=45^{\circ}$

Now,

$m\angle O>m\angle Q>m\angle P$

In a triangle, the greatest angle has largest opposite side and smallest angle has smallest opposite side. So, we conclude that

$PQ>OP>QO$

Therefore, the correct option is C.
