Consider the following incomplete deposit slip: Description Amount ($) Cash, including coins 150 75 Check 1 564 81 Check 2 2192

ololo11 [35]

Given that following incomplete deposit slip:

<span>Description                    Amount ($)

Cash, including coins     $150.75
Check 1                          $564.81
Check 2                       $2,192.43
Check 3                       $4,864.01

Subtotal                       $7,772.00

Less cash received       ($721.50)

Total                             $7,050.50

Therefore, the amount of cash the person who filled out this deposit slip received is $721.50

Verify that -5, 1/2, and 3/4 are the zeroes of the cubic polynomial 4x^3+20x^2+2x-3. Also verify the relationship between the ze

Finger [1]

Solution:

we have been asked to verify that -5, 1/2, and 3/4 are the zeroes of the cubic polynomial $4x^3+20x^2+2x-3$

To verify that whether the given values are zeros or not we will substitute the values in the given Polynomial, if it will returns zero, it mean that value is Zero of the polynomial. But if it return any thing other than zeros it mean that value is not the zero of the polynomial.

Let $f(x)=4x^3+20x^2+2x-3\\\\\text{when x=-5}\\\\f(-5)=4(-5)^3+20(-5)^2+2(-5)-3=-13\\\\\text{when x=}\frac{1}{2}\\$

$f( \frac{1}{2} ) = 4 ( \frac{1}{2} )^3+20(\frac{1}{2})^2+2(\frac{1}{2})-3=\frac{7}{2}\\\\$

$\text{when x=}\frac{3}{4}\\\\$

$f( \frac{3}{4} ) = 4 ( \frac{3}{4} )^3+20(\frac{3}{4})^2+2(\frac{3}{4})-3=\frac{183}{16}\\$

Hence -5, 1/2, and 3/4 are not the zeroes of the given Polynomial.

Since sum of roots $=\frac{-b}{a}= \frac{-20}{4}=-5\\$

But $-5+\frac{1}{2}+\frac{3}{4}= \frac{-15}{4}\neq-5$

Hence we do not find any relation between the coefficients and zeros.

Anyway if the given values doesn't represents the zeros then those given values will not have any relation with the coefficients of the p[polynomial.

–9 = –3(w − 5) help please!

marissa [1.9K]

Answer:

w = 8

Step-by-step explanation:

–9 = –3(w − 5)

-3(w - 5) = -9

w - 5 = 3

w = 5 + 3

w = 8

The level of a lake was 8 inches below normal. It decreased 1

solmaris [256]

Answer:

$-9\dfrac{5}{8}$ inches.

Step-by-step explanation:

The level of a lake was 8 inches below normal.

Now, it is given that the water level decreases $1\dfrac{1}{4} = 1.25$ inches in June and $2\dfrac{3}{8} =2.375$ inches more in July.

Therefore, the new level of water with respect to the normal level will be

= - 8 - 1.25 - 2.375

= - 9.625 inches

= $-9\dfrac{5}{8}$ inches. (Answer)

The equation of line AB is y= 5x+1 . Write an equation of a line parallel to line AB in slope intercept form that contains point

Nadusha1986 [10]

Slope intercept form is: y=mx+b

For the other line to be parallel they must have the same slope so:

y=5x+b, using the point (4,5) we can solve for the y-intercept, or "b"

5=5(4)+b

5=20+b

b=-15 so the line is:

y=5x-15
