It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs
4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground
Answer:
(-3, 4)
Step-by-step explanation:
let the point P(x, y)
x = (5/7 × (-1+8)) + (-8)
= (5/7 × 7) -8 = 5-8 = -3
y = (5/7 × (8+6)) + (-6)
= (5/7 × 14) -6 = 10-6 = 4
so, P => (-3 , 4)
Answer:
(2, 9)
Step-by-step explanation:
We've been given the exponential function;
f(x) = 25(3/5)^x
We need to determine the value of f(x) when x = 2, that is;
f(2) = 25(3/5)^2
Using a calculator we obtain
f(2) = 9
Thus the next point she plots on the graph will be (2, 9)
