Answer: cos A=4/5
Step-by-step explanation:
soh, cah, toa
Adjacent A is 32, hypotenuse is 40
32/40 simplifies to 4/5
Answer:
5x² - 13x + 6
Step-by-step explanation:
8x² - 6x + 2 - (3x² +7x -4)
Simplify the expression:
8x² - 6x + 2 - 3x² -7x + 4
Combine like terms:
5x² - 13x + 6
The value of ac is -1
Step-by-step explanation:
Let us revise some rules
- The slope-intercept form of the linear equation is y = m x + b, where m is the slope of the line and b is the y-intercept
- The product of the slopes of the perpendicular lines is -1
∵ The equation of the first line is y = a x + b
- The equation of the line in the slope-intercept form
∴ m = a
∴ The slope of the line = a
∵ The equation of the second line is y = c x + d
- The equation of the line in the slope-intercept form
∴ m = c
∴ The slope of the line = c
∵ The two lines are perpendicular
∵ The product of the slopes of the perpendicular lines is -1
- Multiply the two slopes and equate the product by -1
∴ (a)(c) = -1
The value of ac is -1
