Answer:

<h2>New salary= $43,800.24</h2>

Step-by-step explanation:

Step one:

Given data

the initial salary is = $42,360

the raise in percentage is =3.4%

To know the raise we need to calculate what the amount of 3.4% of $42,360 is

Step two:

=(3.4/100)*42,360

=0.034*42360

=1440.24

therefore thr raise is $1440.24

Step three:

the new salary is given as

new salary= old salary+ raise

New salary= $42,360+$1440.24

New salary= $43,800.24

Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the x-values at which t

Yakvenalex [24]

Answer:

a. Maximum= 27, minimum= -5

b. Maximum= 19, minimum=-37

Step-by-step explanation:

We have the function $f(x)=8x-5$ . Since the function correspond to a line, then the maximum and minimum values of the function over an interval are in the endpoints of the interval.

Observe that if the line has negative slope then the minimum value is in the right endpoint. If the line has positive slope the minimum value is in the left endpoint of the interval.

The function f(x) has slope m=8. Then

a. the minimum value of f(x) in the interval [0,4] is reach when x=0, and the minimum is $f(0)=8*0-5=-5$ and the maximum is $f(4)=8(4)-5=32-5=27$

b. the minimum value of f(x) in the interval [-4,,3] is reach when x=-4, and the minimum is $f(-4)=8(-4)-5=-32-5=-37$ and the maximum is $f(3)=8(3)-5=24-5=19$

A rectangle has a perimeter of 18 inches. a new rectangle is formed by doubling the with W in tripling the length L as shown the

vladimir1956 [14]

a) The dimensions of original rectangle are length= 5 and width= 4.

b) The dimensions of new rectangle are length= 15 and width=8.

Step-by-step explanation:

length of a rectangle = l
width of a rectangle = w
Perimeter of a rectangle = 2(l+w)

Original rectangle :

18 = 2(l+w)

18 = 2l + 2w ---------(1)

New rectangle :

46 = 2(3l+2w)

46 = 6l + 4w ---------(2)

Solving the equations :

Multiply (1) by 2 and subtract (2) from (1)

4l + 4w = 36

-(6l + 4w = 46)

-2l = -10

l = 10/2

length = 5 inches.

Substitute l=5 in (1)

18 = 2(5)+2w

18 = 10+2w

2w = 8

w = 8/2

width = 4 inches.

length of new rectangle = 3(l) = 3 $\times$ 5 = 15 inches.

width of new rectangle = 2(w) = 2 $\times$ 4 = 8 inches.
