Answer:
-27/4Step-by-step explanation:
Given the quadratic polynomial given as g(x) = x²- 5x + 4, the zeros of the quadratic polynomial occurs at g(x) = 0 such that x²- 5x + 4 = 0.
Factorizing the resulting equation to get the roots
x²- 5x + 4 = 0
(x²- x)-(4 x + 4) = 0
x(x-1)-4(x-1) = 0
(x-1)(x-4) = 0
x-1 = 0 and x-4 = 0
x = 1 and x = 4
Since a and b are known to be the root then we can say a = 1 and b =4
Substituting the given values into the equation 1/a+1/b-2 ab , we will have;
= 1/1 + 1/4 - 2*1*4
= 1 + 1/4 - 8
= 5/4 - 8
Find the Lowest common multiple
= (5-32)/4
= -27/4
Hence the required value is -27/4

A group of 6 students was asked, " How many hours did you watch television last week?" Here are their responses 17 , 15 , 5 , 8 , 20 Find the mean number of hours for these students. If necessary, round your answer to the nearest tenth.
Answer:
13 hours
Step-by-step explanation:
Mean=sum of observations/number of observations
=>17+15+5+8+20/5
=>65/5
=>13
Answer: 14.2
Step-by-step explanation:
The numbers are 17,15,5,8,20, and 20 and to find their mean you need to find their average which their sum divide by the number of values.
17 + 15 + 5 + 8 + 20 + 20 = 85
85 /6 = 14.1666... and rounded to the nearest tenth is 14.2
5) Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her
house and her school. Given FG equals (2x) meters, GH = 1,000 meters, and FH equals 1.200 meters, what is z?
Answer:
Answer:
100 meters
Step-by-step explanation:
Given the following :
Alex house = F
Alex school = H
Alex bus stop = G
FG = 2x meters
GH = 1000meters
FH = 1200 meters
Hence,
FH = FG + GH
1200 = (2x + 1000) meters
1200 = 2x + 1000
1200 - 1000 = 2x
200 = 2x
x = 100meters
Hence, x = 100 meters

If there are 2.54 cm in 1 inch how long is a 36 inch long measuring stick in cm
Answer: The answer is 91.44 centimeters/cm
Step-by-step explanation:
2.54*36= 91.44 centimeters/cm
A 36-inch long measuring stick is equivalent to 91.44 cm.
To convert inches to centimeters, we can use the conversion factor:
1 inch = 2.54 cm
To find out the length of a 36-inch measuring stick in centimeters,
we multiply the length in inches by the conversion factor:
36 inches x 2.54 cm/inch
= 91.44 cm
Therefore, a 36-inch long measuring stick is equivalent to 91.44 cm.

Simplify the expression (4 + 5i)(4 − 5i). 16 − 20i 16 + 20i −9 41
Answer:
41
Step-by-step explanation:
Simplify the following:
(5 i + 4) (-5 i + 4)
Hint: | Multiply 4 + 5 i and 4 - 5 i together using FOIL.
(4 + 5 i) (4 - 5 i) = (4) (4) + (4) (-5 i) + (5 i) (4) + (5 i) (-5 i):
4×4 + 4 (-5 i) + 5 i×4 + 5 i (-5 i)

Mr. and Mrs. Tournas know that their son will attend a college, in 14 years, that they estimate to cost approximately $250,000. How much should they deposit now if they assume that they can earn 8.5% compounded annually?
a) $72,083.41
b) $76,055.32
c) $75,450.20
d) $79,785.45
Answer: D
Step-by-step explanation:
We will try it to determine how much the need to save using the exponential function. In an exponential function,we need the start up amount and the common difference.
We know that the common difference is is 1.085 because if they will earn 8.5% interest plus 100% .
So 1.085 raised to the number of years times a number has to equal 250,000
x * 1.085^14 = 250,000 now solve for x
3.13340357495x = 250,000
x = 79785.44544 Rounded to the nearest cent is $79785.45

Factoring expressions 3x+ 12
Answer:
3(x + 4)
Step-by-step explanation:
Factor out a 3 from both terms, since 3 and 12 are both divisible by 3.
3x + 12
3(x + 4)
So, the factored expression is 3(x + 4)
Answer: 3(x+4)
Step-by-step explanation:
Hii! Do you need to factor the expression 3x+12? No problem! :)
Note that, both 3x and 12 have something in common. This "something" is known as the greatest common factor, or g.c.f.
The g.c.f. of 3x and 12 is 3, so we divide both 3x and 12 by 3
x+4; next we put parentheses around x+4.
(x+4)
Now we put 3 outside the parentheses.
3(x+4)
Voila! There's our solution, cheers!

A ream of a certain brand of paper weighs about 3.225 pounds. A ream contains 500 sheets of paper. How much does a sheet of paper weigh?
Answer:
A single sheet of paper should weigh: 0.00645 pound or [tex]6.45*10^{-3}[/tex] (in scientific notation)
Step-by-step explanation:
Divide 3.225 (the weight of the ream of paper) by 500 (the amount of paper in a ream).
If you need the scientific notation form, simply move the decimal point/place right or left until you end up with a whole number that is between 1 and 10 (in this case, 3 times to the right), then determine what power of 10 it should be, depending on the number of times you moved the decimal place (in this case, the power is -3).
The power/exponent is determined by the direction you have to move your decimal point, right=negative and left=positive. For example, if you started off with the number 6450, you would move the decimal point 3 times to the left and your power would be positive 3, which results in [tex]6.45*10^{3}[/tex].

Two angles are supplementary. One angle is 184° less than three times the other. Find the measures of the angles.
91°, 89°
96°, 84°
86°, 94°
90°, 86°
Answer:
91°, 89°Step-by-step explanation:
The sum of suplementary angles is allways 180°
so:
x - the other angle
3x - three times the other angle
180°- x - one angle
180° - x + 184° = 3x
364° = 4x
x = 91°
180°- x = 180° - 91° = 89°
