Look at the following pairs of numbers (x, y).

katrin2010 [14]

Step-by-step explanation:

Taking the first coordinate point (3,16.5)

where x= 3 and y= 16.5

$\frac{y}{x} = \frac{16.5}{3}$

$\frac{y}{x} = 5.5$

$y = 5.5x$

A stone is thrown upward from ground level. With what minimum speed should the stone be thrown so as to reach a height of 81 fee

butalik [34]

Use the kinematics equation:
v1^2-v0^2=2as
since v1=0 (at height of 81 ft), and a=g=-32.2, substitute values:

0-v0^2=2*(-32.2)(81 ft)
Solve for v0
v0=sqrt(2*32.2*81)=72.2 m/s

Which expression is equivalent?

iVinArrow [24]

Answer:

$\large\boxed{\dfrac{g^{15}}{8h^6}}$

Step-by-step explanation:

$\dfrac{\left(2g^5\right)^3}{\left(4h^2\right)^3}=\dfrac{\left(2g^5\right)^3}{\left(2^2h^2\right)^3}\qquad\text{use}\ (a^n)^m=a^{nm}\ \text{and}\ (ab)^n=a^nb^n\\\\=\dfrac{2^3g^{(5)(3)}}{2^{(2)(3)}h^{(2)(3)}}=\dfrac{2^3g^{15}}{2^6h^6}=\dfrac{2^3g^{15}}{2^{3+3}h^6}\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\dfrac{2^3g^{15}}{2^3\cdot2^3h^6}=\dfrac{g^{15}}{8h^6}$

Find the point-slope equation for the line that passes through the points (5, 35) and (-6, -31). Use the first point in your equ

AleksandrR [38]

Answer:

Maya, this is such a common question on here, so i'm very interested in what's difficult about this problem for you. Please comment about this. Below is the answer and how to find it.

Step-by-step explanation:

point P1 (5,35) in the form (x1,y1)

point P2(-6,-31) in the form (x2,y2)

slope = m

m = (y2-y1) / (x2-x1)

m = (-31-35) / (-6-5)

m = -66 / -11

they made it easy for you , huh

m = 6

use point / slope fomula, y-y1 = m(x-x1) and plug in one point, either would work, since i've already labeled it with point P1, let's use that point

y-35 = 6(x-5)

y-35 = 6x-30

y = 6x - 30 + 35

y = 6x + 5

Maya, this really is a very common question on here, I really am curious about what's tricky in the problem for you and many many others. please let me know in comments section, thanks MMM
