<u>Algebra I</u>

Simple Interest Rate Formula: \displaystyle A = P(1 + r)^t

  • <em>P</em> is principle amount
  • <em>r</em> is rate
  • <em>t</em> is time (in years)

Logarithm Property 1: \displaystyle log(a^x) = xloga

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em>P</em> = 5000

<em>r</em> = 5% = 0.05

<em>A</em> = 25000

<em>t</em> = unknown

<u>Step 2: Solve for </u><em><u>t</u></em>

  1. Substitute in variables [Simple Interest Rate Formula]:                                 \displaystyle 25000 = 5000(1 + 0.05)^t
  2. [Division Property of Equality] Divide 5000 on both sides:                          \displaystyle 5 = (1 + 0.05)^t
  3. (Parenthesis) Add:                                                                                            \displaystyle 5 = (1.05)^t
  4. [Equality Property] log both sides:                                                                  \displaystyle log5 = log[(1.05)^t]
  5. Rewrite [Log Property 1]:                                                                                  \displaystyle log5 = tlog1.05
  6. [Division Property of Equality] Isolate <em>t</em>:                                                          \displaystyle \frac{log5}{log1.05}  = t
  7. Rewrite:                                                                                                             \displaystyle t = \frac{log5}{log1.05}
  8. Evaluate:                                                                                                           \displaystyle t = 32.9869

The wheels on Darlene's car have on 11-inch radius. If the wheels are rotating at a rate of 378 rpm, find the linear speed in mi
elena-s [515]

Answer:

The linear speed in which Darlene is traveling is 24.74 miles per hour.

Step-by-step explanation:

The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed (v), measured in inches per second, is defined by following expression:

v = R\cdot \omega (1)

Where:

R - Radius of the wheel, measured in inches.

\omega - Angular speed, measured in radians per second.

If we know that R = 11\,in and \omega \approx 39.584\,\frac{rad}{s}, then the linear speed, measured in miles per hour, in which Darlene is traveling is:

v = 11\,in\times \frac{1\,mi}{63360\,in} \times 39.584\,\frac{rad}{s}\times \frac{3600\,s}{h}

v \approx 24.74\,\frac{mi}{h}

The linear speed in which Darlene is traveling is 24.74 miles per hour.

-1/4x+2y=28 find the x and y intercept
Advocard [28]
The y intercept is (0, 14) and the x intercept is (-112,0) all you have to do is just make y zero if you are trying to solve for x and the same for the x if you are trying to solve for y.

The quantity a varies directly with b and c and inversely with dThe quantity d is tripledWhich of the following must be true for
EastWind [94]

Answer:

We have the next relation:

A = (b*d)/c

because we have direct variation with b and d, but inversely variation with c.

Now, if we have 3d instead of d, we have:

A' = (b*(3d))/c

now, we want A' = A. If b,c, and d are the same in both equations, we have that:

3bd/c = b*d/c

this will only be true if b or/and d are equal to 0.

If d remains unchanged, and we can play with the other two variables we have:

3b'd/c' = bd/c

3b'/c' = b/c

from this we can took that: if c' = c, then b' = b/3, and if b = b', then c' = 3c.

Of course, there are other infinitely large possible combinations that are also a solution for this problem where neither b' = b or c' = c
