Alex deposits $4,000 in a savings account that pays 5% interest, compounded semiannually. What is his balance after one year?

Answer:

[tex]I_1=40I_2[/tex]

Step-by-step explanation:

[tex]M_1[/tex] = Magnitude of 1994 earthquake = 6.7

[tex]M_2[/tex] = Magnitude of 2014 earthquake = 5.1

[tex]I_1[/tex] = Intensity of 1994 earthquake

[tex]I_2[/tex] = Intensity of 2014 earthquake

[tex]I_0[/tex] = Zero-level earthquake the same distance from the epicenter = 0.001 mm

Magnitude is given by

[tex]M_1=\log(\dfrac{I_1}{I_0})\\\Rightarrow I_010^{M_1}=I_1\\\Rightarrow I_1=I_010^{6.7}[/tex]

[tex]M_2=\log(\dfrac{I_2}{I_0})\\\Rightarrow I_010^{M_2}=I_2\\\Rightarrow I_2=I_010^{5.1}[/tex]

Dividing the above intensities with each other we get

[tex]\dfrac{I_1}{I_2}=\dfrac{I_010^{6.7}}{I_010^{5.1}}\\\Rightarrow \dfrac{I_1}{I_2}=39.81\approx 40\\\Rightarrow I_1=40I_2[/tex]

The intensity of the earthquake in 1994 was 40 times stronger than the earthquake in 2014.

Answer:

Step-by-step explanation:

Step one:

given that the first 3 hours the train travels at a speed of 45 mph.

i.e Time = 3 hours

    speed =45 mph

    distance=?

we know that speed = distance/time

distance= speed*time

distance= 45*3

distance=135miles

Step two:

For the nex two hours it travels at 55 mph

i.e time= 2hours

   speed= 55mph

  distance=?

distance= speed*time

distance= 2*55

 distance= 110mile

Step three:

Hence for a total of 5 hours drive, the total distance covered is

135+110= 245miles

So by that we can write 3m = 15

m is 5.

Answer:

m = -2

General Formulas and Concepts:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define function

y = -2x + 5

Step 2: Break function

Slope m = -2

Answer:

[tex]f(x)=\frac{x^{2} +4x+3}{x^{2} -4x+4}[/tex]

Step-by-step explanation:

The roots are x=-1 and x=-3, so (x+1) = 0 or (x+3) = 0.  As long as one is 0, the product is 0.

(x+1)(x+3) = 0

x^{2} +4x+3=0

So the numerator function is x^{2} +4x+3=0

Answer:

Slope = 1

y-intercept = -1

Step-by-step explanation:

To find the equation, first determine the value of the slope (m) and the value of the y-intercept (b).

Using two points on the line, (0, -1) and (1, 0),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-1)}{1 - 0} = \frac{1}{1} = 1 [/tex]

Slope (m) = 1

The y-intercept is where the line intercepts the y-axis = -1

b = -1

$1000 deductible plan

Step-by-step explanation:

In the $1000 deductible plan, the user pays the least for estimated medical costs of $4,000.

A plan without a deductible usually provides good coverage and is a smart choice for those who expect to need expensive medical care or ongoing medical treatment.

A deductible is an amount you pay out of pocket when you make a claim. Deductibles are usually a specific dollar amount, but they can also be a percentage of the total amount of insurance on the policy.

Step-by-step explanation:

It goes straight through the origin (0,0)

Answer:

16

Step-by-step explanation:

First of all, I think it was "respectively", not "respecfully", =))). A noticeable point.

From the problem, three item's costs are represented by three consecutive even integer.

Thus, we can call cost of spoiler is x, sunroof is x-2, stereo is x + 2. It is conditioned that x is an even number.

Since the sum of the three is 48, we have

(x-2) + x + (x+2) = 48

x+x+x -2 +2 = 48

3x =48

x=16

So the spoiler is 16; thus, the sunroof is 14 and the stereo is 18

Answer:

1/5

Step-by-step explanation:

[tex]\frac{2-1}{3--2} = \frac{1}{5}[/tex]

Answer: 1/5

Step-by-step explanation: Following our hint,

let's start with the slope formula.

m = y₂ - y₁ / x₂ - x₁

We take the second y minus the first y over the second x minus the first x.

So we have m = 2 - 1 / 3 - (-2) or 1 / 5.

So our slope is 1/5.

Step-by-step explanation:

1 Expand.

-6m-12=5-2m−6m−12=5−2m

2 Add 6m6m to both sides.

-12=5-2m+6m−12=5−2m+6m

3 Simplify  5-2m+6m5−2m+6m  to  5+4m5+4m.

-12=5+4m−12=5+4m

4 Subtract 55 from both sides.

-12-5=4m−12−5=4m

5 Simplify  -12-5−12−5  to  -17−17.

-17=4m−17=4m

6 Divide both sides by 44.
