Name two Rays using this figure

Answer:

time =T=6 years

principal = P=$800

rate = R= 2%

interest = (P*T*R)/1000

             = 800*6*2/100

             = 96

Answer:

66.4°

Step-by-step explanation:

Let ∠XYZ be x°.

Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.

[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]

To find the value of x°, take the inverse of cosine.

[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]

Thus, ∠XYZ= 66.4°

*Given 2 sides, we can find the measure of an angle in a right- angled triangle by taking the inverse of the trigonometry function.

Answer:

The answer is "[tex]\bold{T = - 7.5 \cos \frac{\pi}{12}( t - 4 )+ 10.5}[/tex]"

Step-by-step explanation:

Given value:

Temp-maximum=[tex]18^{\circ}[/tex]  

Temp. minimum = [tex]3^{\circ}[/tex]

It is halfway between 10 am and 10 pm to 4 am.  

The sinus and cosine roles could be used throughout the year to predict fluctuations in climate models. Its type of formula that can be used to model such information is:  

[tex]T = A \cos B(t-C) + D,[/tex] where parameters are A, B , C, D, T is the ° C temperature and t is the time (1-24)

[tex]A = amplitude = \frac{(T_{max} - T_{min})}{2}\\\\[/tex]

                       [tex]= \frac{(3 - 18)}{2}\\\\= - \frac{15}{2}\\\\ = -7.5[/tex]

[tex]B = \frac{2 \pi}{24}\\\\[/tex]

   [tex]= \frac{\pi}{12}[/tex]

[tex]C = \text{ units translated to the right}= 4[/tex]

[tex]D = y_{min} + amplitude = units \ translated \ up\\\\[/tex]

D = 7.5 + 3 = 10.5

Its trigonometric function equation that model temperature T hours after midnight in Johannesburg t.

[tex]T = - 7.5 \cos \frac{\pi}{12}( t - 4 )+ 10.5[/tex]

Step-by-step explanation:

Answer: #2. sin x (sin x + 1) = 0

sin x = 0 or sin x + 1 = 0

sin x = 0 or sin x = -1

Step-by-step explanation:

the value of x will be x = 210° and 330° for the given expression (1/2)-sinx=1.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given a equation (1/2)- sin x = 1

Simplifying the given expression

=>  (1/2)- sin x = 1

subtract 1/2 on both sides

=> -sin x = 1/2

=> sin x = -1/2

=> x = 210° and 330°

For all x = 0 to 360°

Answer: − 30 n + 42

Step-by-step explanation:

The product of two positive numbers is always greater than either number the statement is false.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Given that the product of two positive numbers is always greater than either number.

To understand this let's take an example take two numbers and multiply them.

2 x 5 = 10

Then take 2 and 0.5 and multiply them.

2 x 0.5 = 1

Here the result of the product is 1 which is less than 2. Therefore, if the product of two positive numbers is always greater than either number the statement is false.

Answer:

A

Step-by-step explanation:

(-k + 8)(-2k² - 8k - 1)

We can use FOIL to solve this.

(-k * -2k²) + (-k * -8k) + (-k * -1) + (8 * -2k²) + (8 * -8k) + (8 * -1)

2k³ + 8k² + k + (-16k²) + (-64k) + (-8)

2k³ - 8k² - 63k - 8
