Answer:

Option A. $sin(\theta)$

Step-by-step explanation:

we know that

The tangent of angle ∅ is equal to divide the sine of angle ∅ by the cosine of angle ∅

$tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

therefore

The missing value is

$sin(\theta)$

Between the years of 1947 and 1956, earthenware jars containing what are known as the Dead Sea Scrolls were found in caves along

lidiya [134]

Answer:

They are right, the time calculated using the exponential decay equation is 1948.6 years.

Step-by-step explanation:

The time can be calculated using the exponential decay equation:

$N_{(t)} = N_{0}e^{-\lambda t}$ (1)

<u>Where</u>:

N(t): is the quantity of C-14 at time t

N₀: is the initial quantity of C-14

λ: is the decay constant

The decay constant is:

$\lambda = \frac{ln(2)}{t_{1/2}}$ (2)

By entering equation (2) into (1) and solving for t, we have:

$t = \frac{t_{1/2}*ln(N_{t}/N_{0})}{ln(2)} = \frac{5730*ln(0.79)}{ln(2)} = 1948.6 y$

Therefore, the time of the scrolls estimated by the archeologists is right, since the time calculated using the exponential decay equation is 1948.6 years.

I hope it helps you!

-9=u+9/-4 what steps do we take to solve for the variable u?

daser333 [38]

Answer:

you want to isolat U on one side, so subtract 9/-4 from both sides to end up with (9/-4) - 9 = u, then solve. (9/-4)-9 = -11.25, so -11.25 = u

Ariel spent a total of $3.42 buying dried apricots from the bulk bins, which were on sale for $2.85 per pound. To the nearest te

SpyIntel [72]

Answer: 1.2 pounds

Step-by-step explanation:

The cost of one pound of dried apricots = $2.85

The total money Ariel spent on buying dried apricots from the bulk bins = $3.42

Now, the quantity of dried apricots bought by Ariel = $\frac{3.42}{2.85}$

⇒ The quantity of dried apricots bought by Ariel = 1.2 pounds

Therefore, the quantity of dried apricots bought by Ariel = 1.2 pounds
