Multiply: –c2(3c – 2)

Answer:

y=[tex]\frac{1}{2}x-2[/tex]

Step-by-step explanation:

Perpendicular lines have negative reciprocal gradients(slopes) so the slope of your new line would be 1/2. Then you use the point to find the new y-intercept

y=mx+b

2=[tex]\frac{1}{2}[/tex](8)+b

2=4+b

B=-2

y=[tex]\frac{1}{2}x-2[/tex]

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Given

[tex]\triangle JDC[/tex] similar to [tex]\triangle JKL[/tex]

Required

Find x

To do this, we make use of the following equivalent ratios

[tex]JK:JL = JD:JC[/tex]

This gives

[tex]98 : 63 = 7x + 7:27[/tex]

Express as fraction

[tex]\frac{98 }{ 63} =\frac{ 7x + 7}{27}[/tex]

Multiply both sides by 27

[tex]27 * \frac{98 }{ 63} =\frac{ 7x + 7}{27} * 27[/tex]

[tex]27 * \frac{98 }{ 63} =7x + 7[/tex]

[tex]3* \frac{98 }{ 7} =7x + 7[/tex]

[tex]3* 14 =7x + 7[/tex]

[tex]42 =7x + 7[/tex]

Collect like terms

[tex]7x = 42 - 7[/tex]

[tex]7x = 35[/tex]

Divide both sides by 7

[tex]x = 5[/tex]

Answer:

The probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.

Step-by-step explanation:

Since Kelly Slater and Andy Irons are in a surf competition among 10 competitors, to determine, if all surfers are at an equal surfing level, then what is the probability that Kelly will place 1st and Andy will place 2nd, the following calculation must be performed:

1/10 x 1/9 = X

0.1 x 0.11 = X

0.01111 = X

1/90 = 0.011111 = X

Therefore, the probability that Kelly will place 1st and Andy will place 2nd is 1/90, or 1.11%.

Answer:

10.9

Step-by-step explanation:

Given that,

Hypotenuse = 12

One leg = 5

We need to find the another leg. Let it is b. We can solve it using Pythagoras theorem as follows :

[tex]H^2=h^2+b^2\\\\b^2=H^2-h^2\\\\b^2=12^2-5^2\\\\b=10.9[/tex]

So, another leg is 10.9.

Answer:

Step-by-step explanation:

The equation for finding the perimeter of a rectangle is 2Lx2H

So since the length is 16, you multiply that by 2 to get 32.

Then you subtract 32 from 73 which leaves you with 41, then your equation is left as 2H=41, so you divide 41 by 2 which is 20.5, and that is your height

The value of tan(11pi/6) is -√3/(3), the correct option is B.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We are given that;

The trigonometric function= tan(11pi/6)

The value of tan(11pi/6) can be found by using the unit circle or by using trigonometric identities. One way to find it is by using the identity tan(x) = sin(x)/cos(x) and plugging in 11pi/6 for x.

tan(11pi/6) = sin(11pi/6)/cos(11pi/6)

To find sin(11pi/6) and cos(11pi/6), we can use the reference angle pi/6 and recall that sin(pi/6) = 1/2 and cos(pi/6) = √3/2. Since 11pi/6 is in the fourth quadrant, where sine is negative and cosine is positive, we have:

sin(11pi/6) = -1/2

cos(11pi/6) = √3/2

Plugging these values into the expression for tan(11pi/6), we get:

tan(11pi/6) = (-1/2)/(√3/2)

tan(11pi/6) = -1/(√3)

We can rationalize the denominator by multiplying both numerator and denominator by √3:

tan(11pi/6) = (-1/(√3))(√3)/(√3)

tan(11pi/6) = -√3/(√3)(√3)

tan(11pi/6) = -√3/(√9)

tan(11pi/6) = -√3/(3)

Therefore, by the trigonometry the answer will be -√3/(3).

Población = Todos los pasajeros en el autobús

Muestra = los 10 pasajeros entrevistados

Variable = inocencia del conductor; por tanto es una variable cualitativa

Explicación paso a paso:

La población se refiere a todo el conjunto de observaciones que están relacionadas con un evento o experimento en particular. Aquí, todos los pasajeros del vehículo constituyen la población, ya que nuestra investigación se basa en el vehículo.

La muestra es un subconjunto de la población que generalmente se elige al azar de manera que sea representativa de la población.

La variable que pretendemos medir es si el conductor es inocente o no. Por lo tanto, llamamos a esto la variable medida. Debido a que la culpa o la inocencia no es numérica, se considera una variable cualitativa.

Answer:

If all the items are sold, the profit percentage is 14.28%.

Step-by-step explanation:

Given that the cost of 21 articles is equal to selling price of 18 articles, to find the profit or loss percent the following calculation must be performed:

21 = 100

21 - 18 = X

21 = 100

3 = X

(3 x 100) / 21 = X

300/21 = X

14.28 = X

Therefore, if all the items are sold, the profit percentage is 14.28%.
