Answer:
.
Step-by-step explanation:
We are given
and
are zeros of the polynomial
.
We want to find the value of
if
.
Lets use veita's formula.
By that formula we have the following equations:
(-b/a where the quadratic is ax^2+bx+c)
(c/a)
Let's simplify those equations:

If
and
, then
.
Let's solve this for k:
Subtract 6 on both sides:

Find a common denominator:

Simplify:

The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472
Step-by-step explanation:
Each digit in a number has a place value.
The place value of 4 in 453.56 is hundreds (100), because 4 is in the hundred place
The place value of 2 in 1782.56 is ones (1), because 2 is in the unit place
The place value of 3 in 2.345 is tenth (0.1), because 3 is in the tenth place
∵ The number is 581.03
- Find the place of 5 in the number
∵ 5 is in the hundred place
∴ The place value of 5 is 100
∵ The number is 5.472
- Find the place of 5 in the number
∵ 5 is in the unit place
∴ The place value of 5 is 1
To find the value of the 5 in 581.03 is how many times the value of the 5 in 5.472 divide the place values of them
∵ 100 ÷ 1 = 100
∴ The value of 5 in 581.03 = 100 times the value of 5 in 5.472
The value of the 5 in 581.03 is 100 times the value of the 5 in 5.472
The slope would be - 1/2 !!
you would number the x and y values of the coordinates.
( -2 , 5 ) ( -6 , 7 )
x1. y1. x2. y2
then do the formula that gives you the slope y2 - y1 / x2 - x1
this gives you:
7 - 5 / -6 - (-2) = 2/ -4 (simplify) -1/2
so this would give you m= -1/2
Answer:
Therefore required expression is
y =462 - t×15
where y represents the amount of money in her bank account in dollar after t week.
Step-by-step explanation:
Given that,
Holly has $462 in her bank account and takes out $15 each week but does not put any back in.
She takes out $15 on first week.
The remaining amount of her bank account is =$(462-15)
=$(462 - 1×15)
If she withdraws $15 on second week.
The remaining amount of her bank account is =$(462-15-15)
=$(462 - 2×15)
Similarly after third the amount in her account is =$(462 - 3×15)
From the above it is cleared that
The amount in her account after t week is
=$(462 - t×15)
Therefore required expression is
y =462 - t×15
where y represents the amount of money in her bank account in dollar after t week.
