Answer:

The initial weight of the candle is 8 oz.

D.the candle's initial weight

Step-by-step explanation:

the weight is 8 oz when time is 0, initial = 0 s

the initial value represents the candles initial weight before burning it.

To find rate of change:

$\sf \frac{change \ in \ weight}{ time \ taken}$

take two points: (0,8),(5,7)

rate:

$\rightarrow \sf \frac{y1-y}{x1-x}$

$\hookrightarrow\sf \sf \frac{7-8}{5-0}$

$\hookrightarrow\sf-\frac{1}{5}$

$\hookrightarrow\sf -0.2$ is the rate of change.

Find the factors of each number in classify each number as a prime or composite 18,37,48

zepelin [54]

18=1,2,3,9,18

37=1,37

48=1,2,3,16,24,12,4,6,8,48

Prime no. is a number that is divisible only by itself and 1

So, here 37 is a prime no.

18 and 48 are composite no.s

If the slope of a line is -1 and two points on the line are (-9, 3) and (-10, r), what is the value of r?

ANEK [815]

Answer:

$r=4$

Step-by-step explanation:

We know that the slope of the line is -1.

We also know that the line passes through (-9, 3) and (-10, r).

We want to find the value of r.

First, let's figure out the equation of our line. We can use the point-slope form:

$y-y_1=m(x-x_1)$

Where m is the slope and (x₁, y₁) is a point.

So, let's substitute -1 for m. Since we know the point (-9, 3), let's use this for (x₁, y₁).

Substitute:

$y-(3)=-1(x-(-9))$

Simplify:

$y-3=-(x+9)$

Distribute:

$y-3=-x-9$

Add 3 to both sides. So, our equation is:

$y=-x-6$

It passes through (-10, r) and we want to find the value of r. So, let's substitute -10 for x and r for y, since -10 is our x and r is our y. So:

$r=-(-10)-6$

Evaluate for r. Distribute:

$r=10-6$

Subtract:

$r=4$

So, the value of r is 4.

And we're done!

Question 32 of 40 The ratio opposite hypotenuse describes which function?

Helen [10]

The ratio $\frac{Opposite}{Hypotenuse }$ describes the Sine function . The correct option is C. Sine

<h3>Trigonometry </h3>

From the question, we are to determine the function that the ratio of opposite to hypotenuse describes

By SOH CAH TOA

We have that

$Sine = \frac{Opposite}{Hypotenuse }$

$Cosine = \frac{Adjacent}{Hypotenuse }$

and

$Tangent = \frac{Opposite}{Adjacent}$

Hence, the ratio $\frac{Opposite}{Hypotenuse }$ describes the Sine function . The correct option is C. Sine
