X and Y are continuous values, both measured to 2 significant figures. X=230 and Y=400. work out the greatest possible value of

kirill115 [55]

"Two significant figures" means that a digit after the second one could actually be anything ... it wasn't measured. 'X' could be anything from 230 to 239. 'Y' could be anything from 400 to 409. The greatest possible value of that fraction is. (239)/(409 squared) .

What is the inverse of the given relation? Y=7x^2+4

EleoNora [17]

follow these steps:

1) y-4=7x^2

2) (y-4)/7 = x^2

$x = \sqrt{ \frac{y - 4}{7} }$

so you must inverse x and y names:

${f}^{ - 1} (x) = \sqrt{ \frac{x - 4}{7} }$

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenth place.

kap26 [50]

Answer: 68.1

Step-by-step explanation:

The area of a semi-circle is 1/2 the area of a full circle. The area of a full circle is pi*r^2. Therefore, the area of a semi-circle is:

$Area=\pi r^2/2$

$Area=\pi (3)^2/2=9\pi /2$

The area of a rectangle is the length multiplied by the width:

$Area=l*w$

$Area=6*9=54$

The net area is the sum of the rectangle and the semi-circle:

$Area=(9\pi /2)+(54)=68.1$
