Answer:

Consider combining several bar graphs into one large bar graph with a different colors for each time period. By combining bar graphs in this manner, you can more readily see trends for different times periods and notice deviations, which is helpful in making predictions

Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

The atmospheric pressure P on a balloon or in aircraft decreases with increasing height . This pressure measured in Millimeters

Vesnalui [34]

Answer:

(A) 5.47 km

(B) 1.38 km

Step-by-step explanation:

The relationship between Pressure (mmHg) and Height (km) is given by the equation below:

p =760 e⁻ 0.145h----------------------------------------------------- (1)

(a) The height of the aircraft can be calculated by making 'h' the subject of equation (1)

In (p/760) = -0.145 h

h = -In (p/760) /0.145

h= In (760/p)/ 0.145------------------------------------------------- (2)

For the aircraft, p =344 mmHg; substituting into (2)

h = In (760/344)/0.145

= 0.7926/0.145

= 5.4662 km

≈ 5.47 km

(b) p= 622 mmHg at the mountain top. Substituting into equation (2) we have:

h = In (760/622)/0.145

= 0.2003 / 0.145

= 1.3813 km

≈ 1.38 km

A rectangle field is five times as long as it is wide. If the perimeter of the field is 288 yards, what are the field's dimensio

mr_godi [17]

$x + x + 5x + 5x = 288 \\ 12x = 288 \\ x = 24$

Width = 24 yards
Length = 24 x 5 = 120 yards

Area =
$24 \times 120 = 2880 \: sq. \: yrds$

Hope this helps. - M
