Answer:
BC= 2√5
CD= 2√10
DE= 2√5
BE= 2√10
slope of BC = 2
slope of CD = 1/3
slope of DE = 2
slope of BE = 1/3
Step-by-step explanation:
formula for distance = √(x2-x1)²+(y2-y1)²
formula for slope = (y2-y1)/(x2-x1)
Answer:
B. 8.6 cm
Step-by-step explanation:
⅓*πr²h = Volume formula of a cone (V)
Volume of cone (V) = 225 cm³
diameter of cone (d) = 10 cm
radius of cone (r) = ½(10) = 5 cm
height (h) = ?
Plug in the values into the equation and solve for h
⅓ × π × 5² × h = 225
⅓ × π × 25 × h = 225
(25π × h)/3 = 225
Multiply both sides by 3
(25π × h)/3 × 3 = 225 × 3
25π × h = 675
Divide both sides by 25π
h = 675/25π
h ≈ 8.6 cm (nearest tenth)

713*80 = 57040
713*2 = 1426
Answer:
Step-by-step explanation:
4%
A^2+B^2=C^2
7^2+B^2=25^2
49+ B^2=625
Subtract 49
B^2= 576
Sq rt 576
B= 24
