How to solve this equation for the variable b a^2+b^2=c^2 ?
Nata [24]

Firstly, subtract a^2 on both sides: b^2=c^2-a^2

Next, we are going to be using the difference of squares, which is x^2-y^2=(x+y)(x-y) . Use this on the right side of the equation: b^2=(c+a)(c-a)

Lastly, square root both sides of the equation, and <u>your answer will be b=\sqrt{(c+a)(c-a)}</u>

horsena [70]

Answer:

No

Step-by-step explanation:

His answer is incorrect.  If we round the dimensions, 3.76 m is almost 4 m, and 5.49 m is almost 5.5 m.  4 × 5.5 = 22.  So his answer should be close to 22 m².

Maria is using a coordinate plane with the axes labeled only with integers. She says that the point (−0. 5, 2) cannot be plotted
Vinil7 [7]

Maria should move left, half of the division between 0 and -1, and from there, move two divisions or labels upwards.

The point Maria says cannot be plotted is point (-0.5, 2).

The axes label on the coordinate plane Maria is using = Integers.

Given that

Maria is using a coordinate plane with the axes labeled only with integers.

She says that the point (-0.5, 2) cannot be plotted because halves are not numbered on the x-axis.

According to the question

The axes label on a coordinate plane is marked according to the variable associated with the axes.

The values on the axes are presented using appropriate scales, marked as divisions that represent units of measure, such that the quantities which each division of the axis represents are made clear.

Point to be marked on the coordinate plane =(-0.5,2)

As points on both the X and Y axis are integers only.

To mark, -0.5, mark a line between, 0 and -1, which will be,-0.5.

You can mark, any terminating decimal on the number line, which is marked with integers only.

Terminating decimals are those decimals having in the denominator of a fraction.

The ordered pair of points enclosed in parenthesis consist of the x-value located on the left and the value of y is given by the value on the right of the ordered pair.

In the coordinate plane, Maria is using, a division on the coordinate axis represents a unit integer, therefore, to locate a point that is negative half (-0.5) of an integer, Maria has to move left a distance that is half the distance between two points.

Hence, Maria should move left, half of the division between 0 and -1, and from there, move two divisions or labels upwards.
