Answer: B. 36 feet

Step-by-step explanation:

Let h denotes the height of tree

.

According to the question, it can be seen that there is a proportional relationship [Property of similar triangles]  .

\text{i.e.}\dfrac{\text{Tree's height}}{\text{Distance between tree and mirror }}=\dfrac{\text{Jason's height}}{\text{Distance between Jason and mirror}}\\\\\\\Rightarrow\dfrac{h}{42}=\dfrac{6}{7}\\\\\\\Rightarrow\ h=\dfrac{6\times42}{7}=36

Hence, the height of the tree= 36 feet.

True [87]

Answer:

C

Step-by-step explanation:

V(t) = [x(t)]³

A(t) = 6[x(t)]²

dV/dt = k × 6[x(t)]²

Where k < 0

From the options,

taking k = -0.2

worty [1.4K]
This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.
