If p, q are zeroes of polynomial f(x) =2x^2-7x+3,find the value of p^2+q^2​

Mathematics
1 answer:
Elza [17]2 years ago

Answer:

p^2 + q^2 = 22/9.

Step-by-step explanation:

For a quadratic function ax^2 + bx + c if the zeroes are A and B then

A + B = -b/a and AB =  c/a.

2x^2 - 7x + 3

Now p and q are the zeroes of the above function so

p + q =  7/3 and pq = 3/2.

Now p^2 + q^2 = (p + q)^2 - 2pq

= (7/3)^2 - 2* 3/2

=  49/9 - 3

= 49/4 -  27/9

= 22/9.

Nina works at an hourly rate of $12.25 per hour and worked 46 hours last week. She earns overtime for hours exceeding 40 hours.
Alenkinab [10]

Answer:

$600.25

Step-by-step explanation:

12.25 per week

46hrs last week

40+ = overtime

Overtime = t*1.5

------------------------------

46-40= 6hrs of overtime

40*12.25= 490 - this is her money for working 40hrs.

To figure out the money amount of overtime pay--- 12.25*1.5= 18.375 (18.38)

<em>18.38*6= 110.25</em>

add now

<em>110.25+490= $600.25</em>

Each transformation will give these following coordinates

Translation 7 units right gives E(4, 4), F(8, 3), G(10, 6), and H(8, 6) as shown in brown in the diagram below

Reflection on the y-axis gives E(3, 4), F(-1, 3), G(-3, 6) and H(-1, 6) as shown in green in the diagram below

Reflection on the x-axis gives E(-3, -4), F(1, -3), G(3, -6) and H(1, -6) as shown in red in the diagram below

Translation 5 units down gives E(-3, -1), F(1, -2, G(3, 1) and H(1, 1) as shown in purple in the diagram below

Torque (or moment) is the measure of turning force or twist on an object. If a mechanic is applying 12 Newton centimeters of tor
SashulF [63]

Answer:

1.0638

Step-by-step explanation:

Given the question:

If a mechanic is applying 12 Newton centimeters of torque on a bolt how many pound inches would this be?

Torque = 12 Newton centimeter

Torque which is the turning effect on an object :

1 Newton = 0.225 pound force

1 centimeter = 0.394 inch

Hence ;

1 Newton centimeter = (1 × 0.225 × 0.394) = 0.08865 pound inch

12 Newton centimeter is hence, equals :

(12 × 0.225 × 0.394) pound inch

= 1.0638 pound inch
