Left to Right

Step-by-step explanation:

Step 1: Define

m³ - (n + 6 · m) + 4n

m = 2, n = 8

Step 2: Evaluate

Substitute in variables: 2³ - (8 + 6 · 2) + 4(8)
(Parenthesis) Multiply: 2³ - (8 + 12) + 32
(Parenthesis) Add: 2³ - 20 + 32
Exponents: 8 - 20 + 32
Subtract: -12 + 32
Add: 20

Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A 3, 6, \sqrt

dlinn [17]

Answer:

A, B and C

Step-by-step explanation:

Given any three side lengths of a right triangle, the longest side is the hypotenuse.

The side lengths of a right triangle must satisfy the Pythagorean Theorem.

Pythagorean Theorem: $Hypotenuse^2=Opposite^2+Adjacent^2$

Option A: $3, 6, \sqrt{45}$

$(\sqrt{45})^2=3^2+6^2\\45=36+9\\45=45$

True

Option B: 2.5, 6, 6.5

$6.5^2=6^2+2.5^2\\42.25=36+6.25\\42.25=42.25 (TRUE)$

Option C: $4, 8, \sqrt{80}$

$4, 8, \sqrt{80}\\( \sqrt{80})^2=4^2+8^2\\80=16+64\\80=80 (TRUE)$

Since all are true, the side lengths in Options A, B and C forms a right triangle,

Can someone tell me the answer to this plz

Tpy6a [65]

M8 =43.
Reason:
134+ M8 =180(degrees). This is because angles on a straight line =180 (degrees)

180-134=M8
Therefore:
M<8 =180-134= 43 (degrees)

Hope this helps and makes sense.

A geologist in South America discovers a

diamong [38]

Answer:

This is a radioactive decay / half-life problem.

Initial amount of C 14 = 100% Present Amount = 57%

k = .0001 (that value should be negative)

Nt = No * e^ (k*t)

You need to solve that equation for "time" (equation attached)

time = natural log (Ending amount / Starting Amount) / k

time = natural log (57% / 100%) / -.0001

time = ln (.57) / -.0001

time = -.56211891815 / -.0001

time = 5,621.2 years (age of the bird skeleton)

These problems are quite complicated but I think I know this pretty well.
