The time it will take for the block of ice to melt if the temperature is 45 degrees is 3 hours.

The cost to travel 22 miles is 55 dollars.

<h3>How to find how long for the ice to melt?</h3>

let

time it takes for ice to melt = x

air temperature = y

Therefore,

x ∝ 1 / y

x  = k / y

when x = 2.5 hours and y = 54 degrees

Hence,

k = 2.5 × 54

k = 135

The time it will take for the block to melt at 45 degrees = 135 / 45 = 3 hours

<h3>How to find equation that relates the cost to the number of miles?</h3>

It costs $35 for a ride from the city centre to the airport, 14 miles away.

where

c = cost

m = number of miles

Therefore, the equation is as follows:

35 / 14 = 2.5

c = 2.5m

Hence, when you travel 22 miles,

c = 22(2.5)

c = 55 dollars

Which is the graph of the function f(x) = x3 – x2 – 17x - 15?
LenKa [72]

Answer with Step-by-step explanation:

We are given that a function

f(x)=x^3-x^2-17x-15

We have to find the graph of the given function.

y-intercept:It is that  value of y where the graph cut the y- axis.

Let

y=f(x)=x^3-x^2-17x-15

Substitute x=0

Then, we get

f(0)=-15

y-intercept of the graph=-15

x- intercept: It is that value of x where the graph cut the x- axis.

Substitute y=0

x^3-x^2-17x-15=0

Substitute x=-1

-1-1+17-15=0

Therefore,x=-1  is a solution of given equation.

(x+1)(x^2-2x-15)=0

(x+1)(x^2-5x+3x-15)=0

(x+1)(x(x-5)+3(x-5))=0

(x+1)(x+3)(x-5)=0

\implies x=-1,-3,5

Hence, the x-intercept are

-3,-1 and 5

Find the slope of the line between the coordinates (-6,-13) and (3,-1)
Finger [1]

To find the slope of this line, we must use the equation:


slope=\frac{x_{2}-x_{1}}{y_{2}-y_{1}}


Where (x_{1}, y_{1}) and (x_{2}, y_{2}) can be assigned to either point.


Let's use (-6, -13) as the point "1" and (3, -1) as the point "2":


slope=\frac{3-(-6)}{-1-(-13)}


slope=\frac{9}{12} =\frac{3}{4}


So now we know that the slope between these two points is \frac{3}{4}.

Step-by-step explanation:

By PEDMAS, do multiply & division first, then do subtraction

21 ÷ 7 * 3 - 4 * 2    

= (21 ÷ 7 * 3) - (4 * 2)

= (3 * 3) - (8)

= 9 - 8
