A 15-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 14 feet

Finger [1]

Answer:

Step-by-step explanation:

Well certainly friction alone will not hold it there.

c² = a² + b²

15² = 14² + b²

15² - 14² = b²

b² = 29

b = √29 = 5.385164... = 5.39 ft

Given y= 2x squared - 10x find all the real values of x for which y = -3

Thepotemich [5.8K]

$y=2 x^{2} -10x \\ -3=2 x^{2} -10x \\ 2 x^{2} -10x+3=0 \\ x=\frac{-b \pm \sqrt{ b^{2} -4ac} }{2a}, \ where \ a=2, \ b=-10, \ c=3$
Therefore,
$x=\frac{-(-10) \pm \sqrt{ (-10)^{2} -(4 \times 2 \times 3)} }{2 
\times 2} \\ =\frac{10 \pm \sqrt{ 100 -24} }{4} \\ =\frac{10 \pm \sqrt{ 
76} }{4} \\= \frac{10 + \sqrt{ 76} }{4} \ or \ \frac{10 - \sqrt{ 76} 
}{4} \\ =4.679 \ or \ 0.3206$

)) Matt's bill for breakfast at a restaurant was $91. He left an 18% tip. What was the total

gladu [14]

Answer:

$107.38

Step-by-step explanation:

$91 (the price) multiplied by the percentage 18% (91 x 18 = 1630) (1638/100=16.38 [the tip})

$91 (th original price) + 15.38 (the tip) = $108.38 (final price)
