Answer:
648
Step-by-step explanation:
Write 162% as 162
/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have
162
/100 of 400 = 162
/100
× 400
Therefore, the answer is 648
If you are using a calculator, simply enter 162÷100×400 which will give you 648 as the answer
Answer:
λN N(0) = 6
N(t) = N₀e^(λt)
Applying the inital value condition
N(t) = 6e^(λt)
Step-by-step explanation:
Summarizing the information briefly and stating the variables in the problem.
t = time elapsed during the decay
N(t) = the amount of the radioactive substance remaining after time t
λ= The constant of proportionality is called the decay constant or decay rate
Given the initial conditions
N(0) = N₀ = 6
The rate at which a quantity of a radioactive substance decays (
) is proportional to the quantity of the substance (N) and λ is the constant of proportionality is called the decay constant or decay rate :
λN
N(t) = N₀e^(λt) ......equ 1
substituting the value of N₀ = 6 into equation 1
N(t) = 6e^(λt)

Given, (9x - 4)(9x + 4) = ax² - b
From algebraic identities:
We know, (a + b)(a - b) = a² - b²
Now, 81x² + 36x - 36x - 16 = ax² - b
81x² - 16 = axis² - b
So ax² = 81x²
a = 81
-b = -16
b = 16
Solution
Therefore, the value of a is 81.

Answer:
D. y=-2x
Step-by-step explanation:
A linear equation is y=mx+b. M is given as -2. Because the line passes through (0,0), it crosses the y axis at 0.
