$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{a}~,~\stackrel{y_2}{3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{(-1)}}}{\underset{run} {\underset{x_2}{a}-\underset{x_1}{0}}}~~=~~\stackrel{\stackrel{slope}{\downarrow }}{1}\implies \cfrac{3+1}{a}=1\implies 4=a$

Answer:

59.0

Step-by-step explanation:

Given a right angled triangle, ∆XYZ, to know which trigonometric ratio formula to apply in finding the measure of angle X, note the following:

Opposite side to angle X = 6

Hypotenuse = 7

Therefore, we would apply the following trigonometric ratio formula to solve for m<X:

$sin X = \frac{6}{7}$

$sin X = 0.8571$

$X = sin^{-1}(0.8571)$

$X = 58.99$

$m < X = 59.0$ (rounded to nearest tenth)

In your notebook, set up the following subtraction in a vertical format and select the correct answer. Find 2p 2 3p - 4 less - 2

Elena L [17]

The equation in the reduced form of the equation is $\rm 4p^ 2 + 6p - 8$ .

Given that,

Equation; $\rm 2p^ 2 + 3p - 4\ by\ -2p ^2 - 3p +4$

We have to reduce the equation.

According to the question,

To reduce the equation means we need to subtract one equation from the other.

To determine the reduced form of the equation following all the steps given below.

Equation; $\rm 2p^ 2 + 3p - 4\ by\ -2p ^2 - 3p +4$

Subtraction equation 1 from equation 2,

$\rm = \rm 2p^ 2 + 3p - 4\ -(-2p ^2 - 3p + 4)\\\\= 2p^ 2 + 3p - 4\ -(-2p ^2 -3p +4)\\\\ = 2p^ 2 + 3p - 4+2p^ 2 + 3p - 4 \\\\ = 4p^ 2 + 6p - 8$

Hence, The equation in the reduced form of the equation is $\rm 4p^ 2 + 6p - 8$ .

If the absolute value of a number is added to the original number will the sum always equal 0

lbvjy [14]

Not necessarily. the absolute value of a number is that number's distance from 0 on a number line. if your taking the absolute value of a negative value, what you stated would be true. however, what if you took the absolute value of a positive number? hope that answers your question.
