Answer:
a= 3
b.= 3
Step-by-step explanation:
F(x) = ab×
using the 2 given points to find a and b
(0,3)
3=ab⁰
a = 3
(2,27)
27 = 3b² = 9= b²
b = 3
f(x) = 3(3×)

Answer:
Set 4
Step-by-step explanation:
26ft, 6ft, and 9ft will form a triangle
The general form for Pythagoras' theorem is: a² + b² = c² (where c is the longest side).
You already have sides a and b, and to figure out c, you just have to substitute the numbers into the original equation and work it out step by step. Let's substitute a for 17 and b for 24:
a² + b² = c²
(17)² + (24)² = c²
289 + 576 = c²
865 = c²
Square root both sides to work out c:
√865 = √(c²)
c = √865 ≈ 29.41

Answer:
the slope is -8/5
Step-by-step explanation:
we need to get the equation in the form
y= mx+b where m is the slope and b is the y intercept
8x + 5y =40
subtract 8x from each side
8x-8x + 5y = -8x +40
5y = -8x+40
divide each side by 5
5y/5 = -8x /5 + 40/5
y = -8/5 x +8
the slope is -8/5 and the y intercept is 8
