Answer: 25

Form a proportion. Let x be the missing term.

$\frac{60}{144} = \frac{x}{60}$

Solve for x by cross-multiplying.

$144x = 60(60)\\144x = 3600\\x = 25$

The graph shows the cost of some taxi journeys work out a formula for c in terms of n

Vitek1552 [10]

Answer:

$c=\frac{3}{5}(n)+2.5$

Step-by-step explanation:

see the attached figure to better understand the problem

Let

c -----> the cost of some taxi journeys

n ----> the number of miles

we know that

The graph is a line

The equation of a line in slope intercept form is

$c=m(n)+b$

where

m is the slope

b is the c-intercept (value of c when the value of n is equal to zero)

Observing the graph we have the points

(0,2.5), (5,5.5)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{c2-c1}{n2-n1}$

substitute the values

$m=\frac{5.5-2.5}{5-0}$

$m=\frac{3}{5}$

we have

$b=2.5$ -----> because the point (0,2.5) is the c-intercept

substitute in the equation of slope-intercept form

$c=\frac{3}{5}(n)+2.5$

If (3). write the following vectors in column vector form:

Art [367]

Answer:

see explanation

Step-by-step explanation:

Given

a = $\left[\begin{array}{ccc}3\\2\\\end{array}\right]$

To obtain -3a multiply each of the elements of a by -3

3a = $\left[\begin{array}{ccc}-3(3)\\-3(2)\\\end{array}\right]$ = $\left[\begin{array}{ccc}-9\\-6\\\end{array}\right]$

To obtain 1.5a multiply each element by 1.5

1.5a = $\left[\begin{array}{ccc}1.5(3)\\1.5(2)\\\end{array}\right]$ = $\left[\begin{array}{ccc}4.5\\3\\\end{array}\right]$

Solve the following equations x-1=6/x

Whitepunk [10]

Answer:

or,x2-x=6

or,x2-x-6=0

or,x2-3x+2x-6=0

or,x(x-3)+2(x-3)=0

or,(x-3)(x+2)=0

so either x=3

or x=-2
