If this function is:
sin(cos(7/11))
Then it can not be evaluated without a calculator.

If anyone knows the anwser pls tell me
Fudgin [204]

Answer:

z = 156

Step-by-step explanation:

y² = 65²-25² = 4225 - 625 = 3600

(x+25)²-65² = z²

x²+50x+625-4225 = z²

x²+50x-3600 = z²    ....(1)

x²+60² = z²

x²+3600 = z²   ....(2)

(1)-(2): 50x - 7200 = 0

50x = 7200

x = 144

check: x² + y² = z²       144² + 60² = 24336 = z²       z = 156

(25+144)²-65² = z² = 28561 - 4225 = 24336            z = 156

A line passes through (2, 8) and (4, 12). Which equation best represents the line? y = 1 over 2 x 6 y = 2x 7 y = 2x 4 y = 1 over
nalin [4]

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

Given information-

The point through which the line passes are (2, 8) and (4, 12).

To find the equation of the line, the standard form of the equation of the line must be obtained.

<h3>Equation of the line</h3>

Equation of the line is a way to represent the a line in a equation or algebraic from which is the set of the line thorough witch the line passes.

The standard form of the equation of the line can be given as,

(y-y_1)=\dfrac{y_2-y_1}{x_2-x_1} (x-x_1)

Where (x_1,y_1) and (x_2,y_2) are the points through which the line passes.

Thus the equation of the line which passes through the points (2, 8) and (4, 12) can be given as,

(y-8) &=\dfrac{12-8}{4-2} (x-2)\\(y-8) &=\dfrac{4}{2} (x-2)\\2y-16 &=4x-8\\2y &=4x-8+16\\

Divide by 2 both the side,

y=2x-4

Thus the equation of the line which passes through the points (2, 8) and (4, 12) is,

y=2x-4

Hence the option 3 is the correct option.

Which of the following describes how to translate the graph y=|xl to obtain the graph of y=|x| - 4?
WINSTONCH [101]

Answer:

Opt. B

Step-by-step explanation:

The key feature is to eval x in a point where |x| is zero, since the vertex of the function is located at that point.

|x|=0 means that y=-4.

Hence the vertex of this point is located at (0,-4)

4 Units down if we compare with the parent function y=|x|
