Show That 12 cos 30° + 2 tan 60° Can Be Written In The Form √k Where k Is An Integer
Answer:
square root of 192
Step-by-step explanation:
12 cos 30 degrees + 2 tan 60 degrees
= 12* (root 3 /2) + 2* root 3 [as cos 30= root 3/2 and tan 60 = root 3]
=6 root 3 + 2 root 3
= 8 root 3
= square root of 64*3
=square root of 192
= square root of k [ where k = 192 = integer]
Trigonometry ratios are used to represent sine, cosine and tangent functions
The value of [tex]\mathbf{12cos(30) + 2tan(60)}[/tex] is [tex]\mathbf{\sqrt {192}}[/tex]
The trigonometry equation is given as:
[tex]\mathbf{12cos(30) + 2tan(60)}[/tex]
In trigonometry,
[tex]\mathbf{cos(30^o) = \frac{\sqrt 3}{2}}[/tex]
[tex]\mathbf{tan(60^o) = \sqrt 3}[/tex]
So, we have:
[tex]\mathbf{12cos(30) + 2tan(60) = 12 \times \frac{\sqrt 3}{2} + 2 \times \sqrt 3}[/tex]
Evaluate all products
[tex]\mathbf{12cos(30) + 2tan(60) = 6\sqrt 3 + 2 \sqrt 3}[/tex]
Add roots
[tex]\mathbf{12cos(30) + 2tan(60) = 8 \sqrt 3}[/tex]
Express 8 as square root of 64
[tex]\mathbf{12cos(30) + 2tan(60) = \sqrt {64} \times \sqrt 3}[/tex]
So, we have:
[tex]\mathbf{12cos(30) + 2tan(60) = \sqrt {64 \times 3}}[/tex]
Evaluate product
[tex]\mathbf{12cos(30) + 2tan(60) = \sqrt {192}}[/tex]
The form is given as:
[tex]\mathbf{\sqrt {k}}[/tex]
By comparison, we have:
[tex]\mathbf{k = 192}[/tex]
Hence, the value of [tex]\mathbf{12cos(30) + 2tan(60)}[/tex] is [tex]\mathbf{\sqrt {192}}[/tex]

Step-by-step explanation:
When x=-12, y= -128
Look at the table it gives you the values for y when a certain value of X is plugged in the y=-200 - 6(x) equation.
For example, for x=-8, the corresponding y value is -152 because when you plug in x = -8 in equation you get..... y = -200 - 6(-8) = -152
A collection of dimes and nickels has a total value of two dollars and contains 31 coins. How many dimes are there in the collection?
Answer:
There are 9 dimes in this collection.
Step-by-step explanation:
Dimes are 10¢; nickels are 5¢.
d + n = 31
0.1d + 0.05n = 2
In this system of equations, d represents the amount of dimes in this collection and n represents the amount of nickels in this collection.
1. Isolate n in the first equation.
n = -d + 31
2. Substitute this value into the other equation to find the value of d.
0.1d + 0.05(-d + 31) = 2
0.1d - 0.05d + 1.55 = 2
0.05d + 1.55 = 2
0.05d = 0.45
d = 9
If you'd like to know how many nickels are in the collection, just subtract the amount of dimes from the total number of coins in the collection.
31 - 9 = 22
Answer:
9 dimes

∆ABC and ∆PQR are similar. ∆ABC is dilated by a scale factor of 1.25 and rotated 45° counterclockwise about point B to form ∆PQR. The side lengths of ∆ABC are , 5 units; , 4.2 units; and , 4 units. Match each side of ∆PQR to its length.
Answer:
[tex]6.25\ units,\ 5.25 \ units\ and\ 5 \ units[/tex]
Step-by-step explanation:
Given:
The scale factor = 1.25 and rotated =45°
Length of side =5 units; , 4.2 units; and , 4 units respectively.
As mention in the question the ∆ABC and ∆PQR are similar it means there sides are equal .
Therefore sides of the ∆ PQR is
[tex]= (5*1.25),(4.2*1.25),(4*1.25)\\=6.25, 5.25, 5[/tex]
Hence the length of the ∆PQR is [tex]6.25\ units,\ 5.25 \ units\ and\ 5 \ units[/tex]
Christine must buy at least $45$ fluid ounces of milk at the store. The store only sells milk in $200$ milliliter bottles. If there are $33.8$ fluid ounces in $1$ liter, then what is the smallest number of bottles that Christine could buy? (You may use a calculator on this problem.)
Answer:
7 bottles
Step-by-step explanation:
Christie needs to buy at least 45 fluid ounces of milk at the store.
33.8 fluid ounces=1 Liter
1 fluid ounce = [tex]\dfrac{1}{33.8}[/tex] Liters
45 fluid ounces = [tex]\dfrac{1}{33.8} \times 45 =1.3313$ Liters[/tex]
Now:
1 Liter =1000 Milliliter
Therefore:
1.3313 Liter= 1000 X 1.3313 Milliliters
1.3313 Liter= 1331.3 Milliliter
Therefore, the smallest number of 200 milliliter bottles Christie must buy is:
[tex]=\dfrac{1331.3}{200}=6.7 \\\approx 7$ bottles[/tex]

Dos tiendas diferentes ofrecen alquiler de motos mediante los siguientes avisos: MOTOCICLEANDO Paga S/. 35 por la moto que quieras y S/. 2 adicionales por cada kilómetro recorrido. MOTOMOTORS Paga S/.7 por la moto que quieras y S/.16 adicionales por cada kilómetro recorrido. Escribe la expresión que indique el costo del alquiler diario de una moto para una distancia de "x" km recorridos en: la tienda MOTOCICLEANDO:………………………….. la tienda MOTOMOTORS:……………………………… Ahora responde, ¿para qué distancias recorridas conviene alquilar en la tienda? Usa este espacio para escribir tu procedimiento.
Answer:
Las expresiones son:
Ya = 0,35 + 0,2*x
Yb = 0,7 + 0,16*x
Hasta 8,75 Km es preferible alquilar en MOTOCICLEANDO
De 8,75 (sin incluir) en adelante es preferible alquilar en MOTOMOTOR
Step-by-step explanation:
Llamáremos Ya y Yb los costos asociados al alquiler de motos en las tiendas MOTOCICLEANDO y MOTOMOTOR, respectivamente. Entonces, para un recorrido de "x" Km, las expresiones serán:
Ya = 0,35 + 0,2*x y Yb = 0,7 + 0,16*x
Puede observarse que estas expresiones se corresponden con la ecuación de una linea recta, en la cual los términos independientes ( 0,35 y 0,7 ) son los inteceptos de las rectas con el eje y, en los términos que contienen x (0,2*x y 0,16*x ) los coeficientes de esos téminos son las pendientes de las respectivas rectas.
Dada la descripción anterior podemos concluir:
1.-Que las dos rectas se cruzan, antes del cruce los costos que se asocian a la recta de MOTOCICLEANDO son menores que los de la tienda MOTOMOTOR, y a partir de allí se invierte la relación.
Resolviendo tenemos:
0,35 + 0,2*x = 0,7 + 0,16*x
0,2*x - 0,16*x = 0,7 - 0,35
0,04*x = 0,35
x = 0,35/0,04
x = 8,75 Km
Para el intervalo que finaliza a los 8,75 Km es mas económico alquilar en
MOTOCICLEANDO, para la distancia de 8,75 Km es igual y de allí en adelante es mejor alquilar en MOTOMOTOR

Answer: AD = x√3
AD² = 3x²
Step-by-step explanation:
If ΔABC is equilateral and is cut by a perpendicular, then the resulting two triangles (ΔBDA & ΔBDC) are both 30°-60°-90° triangles where
∠A = 30°
∠D = 90°
∠B = ∠C = 60°
In a 30° - 60° - 90° triangle, the corresponding sides have lengths of
↓ ↓ ↓
b b√3 2b
Thus: BD = CD = b
AD = b√3
AB = AC = 2b
Since it is given that AB = 2x, replace the "b" above" with an "x"
BD = x, CD = x
AD = x√3
AB = 2x, AC = 2x

Find the value of y Log^2 32=y
Answer:
Step-by-step explanation:
First of all, I have a strong feeling that that is supposed to be
[tex]log_2(32)=y[/tex] so I'm going to go with that. We can solve for y by rewriting that in exponential form. Exponential form and log form are inverses of each other. If the log form of an equation is
[tex]log_b(x)=y[/tex], the exponential form of it is
[tex]b^y=x[/tex]. We will apply that here to solve for y:
[tex]2^y=32[/tex]
which is asking us, "2 to the power of what equals 32?". We can use our calculator to raise 2 to consecutive powers til we reach the one that gives us a 32, or we could solve it by writing the 32 in terms of a 2:
[tex]2^y=2^5[/tex]
Since both bases are the same, 2, then the exponents are equal to one another. y = 5. This is an important rule to remember while solving either log or exponential equations.
