Sulins savings is 75% of Meifens saving. if Sulin save $300, how much does Meifen save?
Romashka-Z-Leto [24]

9514 1404 393

Answer:

  D) $400

Step-by-step explanation:

We are given the relations ...

  s = 0.75m

  s = 300

Then we can find m by equating the expressions for s:

  0.75m = 300

  m = 300/0.75 = 400

Meifen's savings is $400.

Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (3, 1, 0) and perpendicu
iren2701 [21]

Answer with Step-by-step explanation:

We are given that a point (3,1,0)

Two vectors are

A=<1,1,0>

B=<0,1,1>

A\times B=\begin{vmatrix}i&j&k\\1&1&0\\0&1&1\end{vmatrix}

A\times B=i-j+k

Let v=A\times B=i-j+k

v==

r_0==

r=r_0+vt

Substitute the values then we get

r=+t

r=

The parametric equation of the line

x=x_0+at,y=y_0+bt,z=z_0+ct

Using the formula

The parametric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by

x=3+t,y=1-t,z=t

The symmetric equation of the line is given by

\frac{x-x_0}{a}=\frac{y-y_0}{b}=\frac{z-z_0}{c}

Using the formula

The symmetric equation of the line which is passing through the point (3,1,0) and perpendicular to both i+j and j+k is given by

\frac{x-3}{1}=\frac{y-1}{-1}=z

The time period of a simple pendulum is directly related to the square root of its length. An 8 foot pendulum has a period of 3.
svp [43]

T_1=k \sqrt{8}

T_2=k \sqrt{3}

\frac{T_2}{T_1} = \frac{T_2}{3.2} = \frac{ \sqrt{3} }{ \sqrt{8} }

Then:

T_2=3.2 \sqrt{ \frac{3}{8} } =1.96 secs
