The length of CD is 5 units
The slant height is 39. If you need work show, let me know.
Answer:
x=39
Step-by-step explanation:
<span>Given, y^2 - 14y = -44
Add 44 to both sides of the equation
</span>y^2 - 14y + 44 = -44 + 44<span>
</span>y^2 - 14y + 44 = 0
Using the quadratic formula x = [-b ± √(b² - 4ac)]/2a
Where,
a = 1
b = -14
c = 44
x = [-b ± √(b² - 4ac)]/2a
x = [-(-14) ± √(-14² - 4(1)(44)]/2(1)
x = [14 ± √(196 - 176)]/2
x = [14 ± √20]/2
x = (14 + √20)/2 OR (14 - √20)/2
x = (14 + 4.472)/2 OR (14 - 4.472)/2
x = 18.472/2 OR 9.528/2
x = 9.236 OR 4.764
The solution set is {9.236, 4.764}
TO EXPRESS THE ANSWER IN RADICALS
x = [14 ± √20]/2
x = (14 + √20)/2 OR (14 - √20)/2
x = (14 + 2√5)/2 OR (14 - 2√5)/2
<span>x = 7+√5 OR 7-√5
</span>
The solution set is {7+√5, 7-√5}
Answer:
D
Step-by-step explanation:
The line can be named with small latin letters or with two large latin letters which represent two points lying on the line.
Consider all options:
A. Points V and X lie on the line, so you can name the line as VX (true option)
B. Points W and X lie on the line, so you can name the line as WX (true option)
C. p represents the line (small letter given on the diagram) - (true option)
D. You cannot name the line using point V and line p, so this option is false
