The correct answer is:

D. ∠FGE≅∠NMP

Explanation:

The symmetric property states that if two quantities are equal (or congruent), you can "flip" them around the equals sign (or congruence sign).

This means since EFG is congruent to HJK, then HJK is congruent to EFG.

Answer:

Step-by-step explanation:

In order for ∠NMP to be equal to ∠EFG than you have to move the triangle on it's side. So ∠FGE≅∠NMP is the answer.

Determine which equation has exactly one real solution. PLS HELPP

sergey [27]

Answer:

b) $4x^2-12x+9=0$

Step-by-step explanation:

We can use the discriminant $b^2-4ac$ to determine how many real solutions a quadratic equation in the form $ax^2+bx+c=0$ has.

discriminant > 0 ⇒ 2 real solutions
discriminant = 0 ⇒ 1 real solution
discriminant < 0 ⇒ no real solutions

$5x^2+9x-4=0$

$b^2-4ac=9^2-4(5)(-4)=161 > 0\implies \textsf{2 solutions}$

$4x^2-12x+9=0$

$b^2-4ac=(-12)^2-4(4)(9)=0 \implies \textsf{1 solution}$

$-9x^2+6x+1=0$

$b^2-4ac=6^2-4(-9)(1)=72 > 0 \implies \textsf{2 solutions}$

$-2x^2-7=0$

$b^2-4ac=0^2-4(-2)(-7)=-56 < 0 \implies \textsf{no solutions}$

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!

HELP!! FAST!!

maks197457 [2]

Answer: Choice D

$x_n = f(x_{n-1})$

This basically says "the nth term is found by computing math, aka evaluating some function, based on the (n-1)th term".

As an example, we could have a function that simply squares the input

Let's say we started at 5. It squares to 25 which in turns squares to 625, and so on. Each new term is based on the old term. Namely, we squared the old n-1 term to get the new nth term.
