I will say 1 block is 1 something okay cause I don’t have a key mini has an area of 2 (2x2=4/2=2) And the giant has an area of 32 (8x8=64/2=32) I don’t know if the small one became big or the big one became small so if the small to big is 16 big to small is 0.0625 or the numbers the other way around

Answer:

Area of left triangle = 2 * 2 / 2 = 2

Area of triangle on the right = 8 * 8 / 2 =32

32 / 2 = 16

Therefore the triangle on the right has 16 times the area than the triangle on the left.

Answer:

<em>M(13)=14.3 gram</em>

Step-by-step explanation:

<u>Exponential Decay Function</u>

The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.

The equation of the model is:

$M(t)=M_o\cdot(1-r)^t$

$M(t)=970\cdot(1-0.277)^t$

Operating:

$M(t)=970\cdot 0.723^t$

After t=13 minutes the remaining mass is:

$M(13)=970\cdot 0.723^{13}$

Calculating:

M(13)=14.3 gram

K anyone help please

tigry1 [53]

Answer:

Step-by-step explanation:

Given equation is,

a). y = $\frac{6}{x}$

x 0.5 1 2 3 4 5 6

y $\frac{6}{0.5}=12$ $\frac{6}{1}=6$ $\frac{6}{2}=3$ $\frac{6}{3}=2$ $\frac{6}{4}=1.5$ $\frac{6}{5}=1.2$ $\frac{6}{6}=1$

b). By plotting the input-output values on the graph we get the curve as shown in option C.

Therefore, Option C will be the answer.
