What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
An airplane is flying in the direction of 30 degrees South of West at 600 mph. A wind is blowing in the direction of 60 degrees North of East at 40 mph.
It means the airplane is flying in the opposite direction of the wind.
The component of an airplane will be
[tex]x=-600sin30\\\\x=\dfrac{-600}{2}=-300\\\\y=-600cos30\\\\y=\dfrac{-600 \sqrt{3}}{2}}[/tex]
The component of wind will be
[tex]x=40cos60\\\\x=\dfrac{40}{2}=20\\\\y=40sin45\\\\y=\dfrac{40\sqrt{3}}{2}}[/tex]
Then the ground speed will be
.[tex]G=\sqrt{(600\dfrac{\sqrt{3}}{2}+20)^2+(300+40\dfrac{\sqrt{3}}{2}})^2}[/tex]
Then the correct potion is B.

What is the inverse of `y = 5x + 7
Show Steps!
Answer:
[tex]\sf y' = \dfrac{x-7}{5}[/tex]
Explanation:
⇒ y = 5x + 7
⇒ 5x + 7 = y
⇒ 5x = y - 7
⇒ x = (y-7)/5
replace x with y
⇒ y' = (x-7)/5
Take this and solve for x
5x=y-7x=y-7/5Interchange y and x
y=x-7/5So
The inverse is
[tex]\\ \rm\dashrightarrow y^{-1}(x)=\dfrac{x-7}{5}[/tex]
Find the measurement for x.
Answer:
x=120 degrees
Step-by-step explanation:
All triangle add up to 180 degrees so first you need to finnish the triangle which is 60 degrees. X and 60 degrees is on a straight line which means something + 60= 180.
(180-60=120)
x= 120

La siguiente tabla presenta las frecuencias absolutas y relativas de las distintas caras de un dado cuando se simulan 300 lanzamientos en una página web: Si ahora se simulan 600 lanzamientos en la misma página web, Marcos cree que la frecuencia relativa de la cara con el número 6 será 0,36, porque se simula el doble de los lanzamientos originales. Por otro lado, Camila cree que la frecuencia relativa de la cara número 6 se acercará más al valor 0,166, tal como el resto de las frecuencias relativas de la tabla
La opinión correcta es la de Camila que argumenta que la frecuencia relativa de la cara con el #6 será un valor cercano a 0,166.
Qué es la frecuencia relativa?La frecuencia relativa es un término matemático que se utiliza en la estadística para referirse al número de veces que un evento se repite durante un experimento.
Por otra parte, es necesario aclara que la frecuencia relativa no se modifica en gran medida si se aumenta el número de veces de una prueba, debido a que la probabilidad de ocurrencia de este evento va a ser la misma.
De acuerdo a lo anterior, Camila tiene razón debido a que considera que el valor de la frecuencia relativa no se modifica en gran medida entre 300 o 600 lanzamientos de los dados.
Nota: Esta pregunta está incompleta porque no está la tabla. No obstante, la puedo responder basado en mi conocimiento previo.

Landon Wallin is an auto mechanic who wishes to start his own business. He will need $4100 to purchase tools and equipment. Landon decides to finance the purchase with a 60-month fixed installment loan with an APR of 6%.
a) Determine Landon's finance charge.
b) Determine Landon's monthly payment.
Answer:
a.$1230
b.$20.50
Step-by-step explanation:
Assuming Landon only makes the minimum payments for the sixty months this is how you would find it
Multiply loan by percentage over the five years: 4100 x .3 = 1230
Then divide that amount by months paid: 1230/60= 20.5

Answer:
50.24
Step-by-step explanation:
4²=16
16×3.14=50.24
Firstly, we must use the equation to solving a circle which is [tex]A = \pi r^2[/tex]. Since we already know pi (3.14) and the radius (4), we must plug the numbers into the formula. Here is how it should look like with the plug-ins: [tex]A = 3.14 * 4^2[/tex].
Next, we solve the formula. After solving, we get 50.24. The final answer to the problem is 50.24 inches squared.

Answer:
One tank can hold, on average, 108.1 gallons of water. A half tank will hold 54.05 gallons of water.
Step-by-step explanation:
432.4 galloons in total in 4 tanks
432.4 : 4
? : 1
432.4/4=108.1, so 108.1 gallons in each tank
Half of 108.1 is 54.05, so half a tank would have 54.05 gallons.
