Hey there!

The common ratio is 5, because you multiply by 5 to get from one term to the next.

Hope this helps :)

I don't know how to get the answer, but I've been given the answer and it's x=ln 8.
Pie
E^2x - 5e^x = 24

(e^x)^2 - 5e^x =24

let e^x = u

u^2 - 5u = 24

u^2 -5u - 24 =0

(u - 8)(u+3)=0

u = 8 or u = -3

since e^x = u then u can't equal -3

e^x = 8

by taking ln for both sides

ln(e^x) = ln(8)

xln(e) = ln(8) .......................ln(e) = 1

x = ln(8) = 3ln(2)

Please help !! I would really appreciate it

Answer:

Runner 1

Step-by-step explanation:

Runner 1's speed is the slope of the line = (20-0)/(2-0) = 10

Runner 2's speed is the slope of the line = 8.5 (the coefficient of t)

Runner 3's speed is slope = (36-18)/(4-2) = 9

The fastest pace, therefore is of runner 1, because 10>9 AND 10>8.5

A triangle has sides with lengths of 4 yards, 10 yards, and 11 yards. Is it a right triangle?
vodka [1.7K]

Answer:

no

Step-by-step explanation:

for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse

a² + b² = c²

in this problem, 4² + 10² ≠ 11²

16 + 100 ≠ 121
