Answer:
the answer is 31.9 years
Step-by-step explanation:
initial mass,
= 150 gram
half life,
= 32 years
new mass = half of initial mass = M = 0.5
formula , M =
where x is the number of years required.
therefore 0.5
=

therefore -0.0217 x =
therefore x =
= 31.942

Answer:
Center of dilation origin, The scale factor is 4, The dilation mapping is (x, y) → (4x,4y) and The image represents the shape of the triangle.
Step-by-step explanation:
Given Hector is making an art project by cutting and gluing fabric shapes to a wooden board. His design includes two similar triangles, with one 4 times the size of the other. He cuts the smaller fabric triangle and traces it onto grid paper. we have to tell how he can use the tracing to make a pattern for the larger fabric triangle.
Apply the center of dilation origin.
The scale factor is 4
The dilation mapping is (x, y) → (4x,4y)
The image represents the shape of the triangle.

We simplify to get:



14 and 15.
the square root of 14 is 196.
the square root of 15 is 225.
200 is in between those 2 numbers
