HELP HELP PLEASE!! D: Determine the missing side length: Please don't give cap!

viktelen [127]

Answer:

c = 35

Step-by-step explanation:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 21^{2} + 28^{2}$

$c^{2} = 1225$

$\sqrt{c^{2} } = \sqrt{1225}$

$c = 35$

PLEASE HELP QUICK What is the slope-intercept form of the linear equation 2x + 3y = 6?

Salsk061 [2.6K]

Answer:

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

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x + 3y = 6 into this form

subtract 2x from both sides

3y = - 2x + 6 ( divide all terms by 3 )

y = - $\frac{2}{3}$ x + 2 ← in slope-intercept form

A square steel bar has a length of 7.4 ft and a 2.9 in by 2.9 in cross section and is subjected to axial tension. The final leng

Answer:

Poission Ratio = 0.2784

Step-by-step explanation:

we know that

Poission ratio is defined as

μ = $\frac{-lateral strain}{longitudinal strain}$

We also know that lateral strain = $\frac{Final width-Initial width}{Initial Width}$

In our case

Final width = 2.89945 in

Initial width = 2.9 in (Area of cross section (width x depth) = 2.9 in x 2.9 in)

Thus lateral strain = $\frac{2.89945-2.9}{2.9}$

Lateral strain = $-1.8965X10^{-4}$

Similarly longitudinal strain = $\frac{Final Length-Initial Length}{Initial Length}$

Thus longitudinal strain = $\frac{7.40504ft-7.4ft}{7.4ft}$

Longitudinal strain = $6.8108X10^{-4}$

Thus by formula poission ratio = $\frac{-(-1.8965X10^{-4}}{6.8108X10^{-4}}$

Poission Ratio = 0.2784

If f(x) = 2x and g(x) = sqrt x,what is the domain of (fog)(x)?

Norma-Jean [14]

Answer:

All Real x larger or equal zero

or in inequality form: $x\geq 0$

or in interval notation: $[0,\infty)$

Step-by-step explanation:

If $f(x)=2x$ and $g(x)=\sqrt{x}$ , then using the definition for the composition of functions $(fo\,g)(x)=f(g(x))$ , we get:

$(fo\,g)(x)=f(g(x)) \\(fo\,g)(x)=f(\sqrt{x} )\\(fo\,g)(x)=2\,\sqrt{x}$

Base on this final expression, we understand that the Domain (numbers that can be used as input of the function and produce a real number as result) of this new function is limited to those x-values larger than or equal to zero. Negative numbers inside the square root will not produce a real number.

Therefore, the Domain is restricted to All Real numbers larger than or equal to o (zero).

This statement can also be given in inequality form as $x\geq 0$

or in interval notation: $[0,\infty)$
