Step-by-step explanation:

Given

[tex]P = 22400[/tex] --- initial value

[tex]r = 12\%[/tex] -- rate

[tex]A = P(0.88)^t[/tex] --- function

Required

Find t when [tex]A = 10000[/tex]

We have: [tex]A = P(0.88)^t[/tex]

Substitute: [tex]A = 10000[/tex] and [tex]P = 22400[/tex]

[tex]10000 = 22400 * 0.88^t[/tex]

Divide both sides by 22400

[tex]0.4464 = 0.88^t[/tex]

Take log of both sides

[tex]\log(0.4464) = \log(0.88^t)[/tex]

Apply law of logarithm

[tex]\log(0.4464) = t\log(0.88)[/tex]

Solve for t

[tex]t = \frac{\log(0.4464)}{\log(0.88)}[/tex]

[tex]t = \frac{-0.3503}{-0.0555}[/tex]

[tex]t = 6.31[/tex]

[tex]t \approx 6.3[/tex]

A train ticket in a certain city is$1.50. People who use the train also have the option of purchasing a frequent rider pass for $15.75each month. With the pass, each ticket costs only $0.75. Determine the number of times in a month the train must be used so that the total monthly cost without the pass is the same as the total monthly cost with the pass.

Answers

Answer:

The value of X is 4, and the area of the triangle is [tex]60^2 units[/tex].

Step-by-step explanation:

First we need to add up all the sides. Doing so will give us the equation [tex]8x+8=40[/tex]. Subtracting 8 from both sides will give us [tex]8x=32[/tex]. Next we divide both sides by 8 in order to isolate the variable, which gives us [tex]x=4.[/tex]

This gives us 4 as our value of x.

Now we need to find the area. Substituting x into the values for base and height will give us 8+7 = 15 for our height, and 4+4=8 for our base. 15*8 is 120, and divided by two gives us 60 as out area.

Thus, x=4 and area=60.

Za and Zb are
complementary angles. Za measures 59º.
What is the measure of Zb?

Answers

Complementary angles are two angles whose sum adds up to 90 degrees
Za + Zb = 90
You know Za measures 59
59 + Zb = 90

Solution: Zb is 31 degrees

Answer:

Zb = 31

Step-by-step explanation:

Complementary angles mean that the angles add up to 90 so:

Za + Zb = 90

59 + Zb = 90

Zb = 90 - 59

Zb = 31

Answers

Answer:

48.2 cm

Step-by-step explanation:

The bottom side of the large triangle has length 78 cm.

The bottom side of the right triangle has length 78 cm/2 = 39 cm.

Now we use the Pythagorean theorem to find the vertical side, the spine.

39² + s² = 62²

s² = 3844 - 1521

s² = 2323

s = 48.2

Set up a proportion to find the total number of fl oz from the 6 cups, let variable x be the total oz of the 6 cups:

The answer should be 48 fl oz, then you add the 4 fl oz to have the total of 52 fl oz.

[tex]\tan(30) = \frac{\sqrt 3}{3}[/tex]

[tex]\tan(60) = \sqrt 3[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find [tex]\tan(30)[/tex] and [tex]\tan(60)[/tex]

The tangent of an angle is calculated as:

[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

So, we have:

[tex]\tan(30) = \frac{b}{a}[/tex]

This gives:

[tex]\tan(30) = \frac{3}{3\sqrt 3}[/tex]

3 cancels out

[tex]\tan(30) = \frac{1}{\sqrt 3}[/tex]

Rationalize

[tex]\tan(30) = \frac{1}{\sqrt 3} * \frac{\sqrt 3}{\sqrt 3}[/tex]

[tex]\tan(30) = \frac{\sqrt 3}{3}[/tex]

Similarly;

[tex]\tan(60) = \frac{a}{b}[/tex]

This gives:

[tex]\tan(60) = \frac{3\sqrt 3}{3}[/tex]

3 cancels out

[tex]\tan(60) = \sqrt 3[/tex]
