Answer:

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

Each letter of the alphabet is assigned a numerical value according to its position in the alphabet. Encode the message SEND âHE

SCORPION-xisa [38]

Answer:

Step-by-step explanation:

Given the encoded message defined by the function f(x) = x³-1, the inverse function that the decoder would need when the message is received can be expressed as thus:

let the inverse of the function be represented as y such that y = x³-1.

Making x the subject of the formula from the equation above;

x³ = y+1

Taking the cube root of both sides:

∛x³ = ∛(y+1)

x = ∛(y+1)

replacing y with x:

y = ∛(x+1)

f⁻¹(x) = ∛(x+1)

The encoded message is the inverse function ∛(x+1)

If yo travel56mph how far will you go in2hr15min how long does it take to cover 168 miles

Alex73 [517]

2 hr 15 min = 2 $\frac{1}{4}$ hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 = 126 miles

"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
