The graph represents the journey of a bus from the bus stop to different locations:

Igoryamba

Answer:

Part A:

For number 1, the bus drives non-linear. It is not a constant rate but it is increasing.

For number 2, the bus is at a stopping point.

For number 3, the bus drives in a non-linear rate but it still increasing.

For number 4, the bus is at its last stop, the middle of the bus ride, the peak of the time.

For number 5, the bus comes to a non-linear decrease in the route. and eventually the end.

Part B:

The bus is increasing in numbers 1 and 3, and decreasing for number 5, and at a constant at numbers 2 and 4.

Part C:

The graph is non-linear, as the slope is not at a constant.

Two quantities vary inversely. If the value of the first is 15 when the value of the second is 18, find the value of the second

vovikov84 [41]

Answer:

The value of second quantity is 27

Step-by-step explanation:

Inverse variation can be represented by the equation xy=k or $y = \frac{k}{x}$ i.e,

y varies inversely as x , if there is some nonzero constant k such that, xy =k or $y = \frac{k}{x}$ where x≠0 and y≠0.

Given: Two quantities vary inversely.

Let x be the first quantity and y be the second quantity if they vary inversely.

then, by definition of inverse variation;

$y = \frac{k}{x}$ .....[1]

Substitute the value of x=15 and y=18 to solve for k;

$18= \frac{k}{15}$

Multiply both sides by 15 we have;

$15\times 18=15 \times \frac{k}{15}$

Simplify:

k=270

now, find the second quantity y using same method when x=10.

then;

after substituting the value of x=10 and k=270 in [1] ;

$y = \frac{270}{10}$

Simplify:

y= 27

Therefore, the second quantity value i.e,y = 27

GEOMETRY Holly can make an open-topped box out of a square piece of cardboard by cutting 3-inch squares from the corners and fol

cluponka [151]

Answer:

$V(x)=3(x-6)(x-6)$

Step-by-step explanation:

<u>Polynomial Factoring</u>

The volume of a cardboard box is expressed as:

$V(x)=3x^2-36x+108$

It's required to factor that expression.

First, factor out 3:

$V(x)=3(x^2-12x+36)$

The expression in parentheses is a perfect square:

$\boxed{V(x)=3(x-6)(x-6)}$
