Reduced by 20% due to the fact that $40 dollars was removed which is 20% of 200.
How to find: 40/200x100

Percentage change = change/original, x100
so it's 40/200 x100, which is 20.

You and your friend drive toward each other. The equation 50h=190−45h represents the number h of hours until you and your friend

Gala2k [10]

Answer:

The answer is 2 hours later.

Step-by-step explanation:

In order to find how many hours you and your friend meet, you have to solve the equation to find h :

$50h = 190 - 45h$

$50h + 45h = 190$

$95h = 190$

$h = 190 \div 95$

$h = 2$

Write the equation for a parabola that has x-intercepts (−4.5, 0) and (−2.8, 0) and y-intercept (0, 37.8).

BARSIC [14]

Answer:

$y = 3(x + 4.5)(x + 2.8)$ .

Step-by-step explanation:

Start with the two $x$ -intercepts. The two zeros of the quadratic equation for this parabola are:

$x_1 = -4.5$ , and
$x_2 = 2.8$ .

(These are the $x$ -coordinates of the two $x$ -intercepts.)

By the factor theorem, $x = k$ (where $k$ is a real number) is a zero of a polynomial if and only if $(x - k)$ is a factor of that polynomial.

A quadratic equation is also a polynomial. In this case, the two zeros would correspond to the two factors

$(x - (-4.5)) = (x + 4.5)$ .
$(x - (-2.8)) = (x + 2.8)$

A parabola could only have up to two factors. As a result, the power of these two factor should both be one. Hence, the equation for the parabola would be in the form

$y = a \, (x + 4.5)(x + 2.8)$ ,

where $a$ is the leading coefficient that still needs to be found. Calculate the value of $a$ using the $y$ -intercept of this parabola. (Any other point on this parabola that is not one of the two $x$ -intercepts would work.)

Since the coordinates of the $y$ -intercept are $(0,\, 37.8)$ , $x = 0$ and $y = 37.8$ . The equation $y = a \, (x + 4.5)(x + 2.8)$ becomes:

$37.8 = a \, (0 + 4.5)(0 + 2.8)$ .

Solve for $a$ :

$\displaystyle a = \frac{37.8}{4.5\times 2.8} = 3$ .

Hence the equation for this parabola:

$y = 3(x + 4.5)(x + 2.8)$ .

Determine the remainder when (5x3 + 49x2 + 74x + 6) is divided by (x + 8).

klio [65]

The polynomial remainder theorem says that the remainder when dividing a polynomial $P(x)$ by a linear divisor $x-k$ is simply $P(k)$ .

If $P(x)=5x^3+49x^2+74x+6$ , then the remainder upon dividing by $x+8$ is

$P(-8)=-10$

You could also verify this by actually computing the quotient and remainder.
