8x6= 48 (not necessary to divide by 8 since you'd have to multiply it by 2 anyway because there are 2 triangles)
6x12=72
10x12=120
12x8=96

48+72+120+96=336

336cm^2 is the answer

C; 120 because 24x=360 so x=15. Then ABC is 8x, so 8*15=120.

Answer:

t = 8588 years

Step-by-step explanation:

From the given information:

Using the formula:

$k = \dfrac{In (2)}{t_{1/2}}$

Given that:

$t_{1/2}$ = 5730 years

Then:

$k = \dfrac{In (2)}{5730}$

$k = \dfrac{0.6931472}{5730}$

k = 1.20968 × 10⁻⁴

However; the expression to find the value of x is:

$x= x_oe^{-kt}$

$4.6 \times 10^{-13} = 1.3 \times 10^{-12} \times e^{(-1.20968\times 10^{-4} \times t)}$

$\dfrac{4.6 \times 10^{-13} }{1.3 \times 10^{-12}}= e^{(-1.20968\times 10^{-4} \times t)}$

$0.353846= e^{(-1.20968\times 10^{-4} \times t)}$

(-1.20968 × 10⁻⁴ × t) = In(0.353846)

(-1.20968 × 10⁻⁴ × t) = -1.03889

$t = \dfrac{-1.03889}{-1.20968 \times 10^{-4}}$

t = 8588 years

Exercise 1: In the right triangle below, calculate the measurement of the unknown side. Show your work.

vekshin1

Answer:

Exercise 1:

base [b]=8cm

perpendicular [p]=6cm

hypotenuse [h]=?

By using Pythagoras law

h²=p²+b²

h²=6²+8²

h=√100

h=10cm

So another side's length is 10cm

Exercise 2:

base [b]=6m

perpendicular [p]=bm

hypotenuse [h]=8m

By using Pythagoras law

h²=p²+b²

8²=b²+6²

b²=8²-6²

b=√28=2√7 0r 5.29 or 5.3

So height of kite is√28or 2√7 0r 5.29 or 5.3 m
