As a decimal, it's 0.56
As a fraction, 56/100
I hope that helps!
Answer:
1. <u>Average velocity</u>
When t=4
i. [4, 4.1]
= y(4.1) - y(4) / 4.1 - 4
= 275 - 16(4.1)^2 - 275 - 16(4)^2 / 0.1
= 275 - 16*16.81 - 275 - 16(16) / 0.1
= 6.04 - 19 / 0.1
= -12.96 /0.1
= -129.6
ii. [4, 4.05]
= y(4.05) - y(4) / 4.05 - 4
= 275 - 16(4.05)^2 - 275 - 16(4)^2 / 0.05
= 275 - 16*16.40 - 275 - 16(16) / 0.05
= 12.6 - 19 / 0.05
= -6.4 / 0.05
= -128
iii. [4, 4.01]
= y(4.01) - y(4) / 4.01 - 4
= 275 - 16(4.01)^2 - 275 - 16(4)^2 / 0.01
= 275 - 16*16.08 - 275 - 16(16) / 0.01
= 17.72 - 19 / 0.01
= -1.28 / 0.01
= -128
b. Instantaneous velocity
y = 275 - 16t^2
dy/dx = -32t
Considering t = 4
Instantaneous velocity after 4 seconds = -32(4)
Instantaneous velocity after 4 seconds = -128
The age of the radioactive artifact is approximately 19029.6 years old
<h3>Radioactivity</h3>
Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei to atomic nuclei to form more energetically stable atomic nuclei. Radioactive decay is a highly exoergic, statistically random, first-order process that occurs with a small amount of mass being converted to energy.
To solve this problem, we have to find the disintegration constant and we can use the formula of half-life of the sample to do that.
The half-life of a sample is given as;
The formula of radioactivity is given as
Substituting the values into the equation
The artifact is approximately 19029.6 years.

Answer:
i think it 330
Step-by-step explanation:
1<em>.) </em><em>Reduction</em>
<em>As you can see Triangle A was reduced in size as a result of Triangle B</em>
<em>2.) </em><em>Enlargement</em>
<em>Square A is much smaller than square B, making this an enlargement</em>
<em>3.) </em><em>Enlargement</em>
<em>The quadrilateral shown here gets larger with quadrilateral B</em>
<em>4.) </em><em>Reduction</em>
<em>This object gets vividly smaller as shown on the graph, making it a reduction </em>
