Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.

Write an equation in point-slope form of a line that goes through the points (1,4) and (3,-10). Do not use any spaces in your an
olasank [31]

Answer:

y-4=-7(x-1) OR y-(-10)=-7(x-3)

Step-by-step explanation: The point-slope form is y_-y_{1}=m_(x_-x_{1})

In slope-intercept form, the equation would be y = -7x + 11

You could find the slope by using the slope equation, \frac{y_{2} -y_{1} }{x_{2} -x_{1} }.

Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.

Montano1993 [528]
Multiply the constants. Multiply the variables according to the rules of exponents.
(-2q^{4})(-8q^{3}b^{6}) = ((-2)(-8))q^{(4+3)}b^{6}\\\\=16q^{7}b^6}

Food inspectors inspect samples of food products to see if they are safe. This can be thought of as a hypothesis test with the f
Novay_Z [31]

Answer:

Type II error

Step-by-step explanation:

According to the definition of type II error, the type II error arises when we wrongfully accept the null hypothesis. It means that when we accept our null hypothesis and null hypothesis is not correct then type II error arises. So according to situation we are accepting the null hypothesis that the food is safe but it is actually not safe. Hence the given situation represents type II error.
