You need the angle of the line between the shadow and the line from the extreme of the shadow to the cup ot the tree.

Suppose that the angle is the same of a right triangle with a base of 5 ft and a tall of 2 ft.

=> 2/5 = x / 30ft => x = 30ft * 2 / 5 = 12ft

=> The tree is 12 ft tall.

And the two triangles are similar (they have same angles).

Functions f(x) and g(x) are described as follows: f(x) = −5x2 + 9 x g(x) 0 0 1 4 2 8 3 4 4 0 Which statement best compares the m
MArishka [77]

Which statement best compares the maximum value of the two functions?

A. It is equal for both functions

B. It is 3 units higher for f(x) than g(x)

C. It is 3 units lower for f(x) than g(x)

D. It is 1 unit higher for f(x) than g(x)

Solution : D. It is 1 unit higher for f(x) than g(x)

Given:

f(x) = −5x^2 + 9

g(x) is 0 0 1 4 2 8 3 4 4 0

We make a table for f(x) as well. We use same x vales given in g(x)

We plug in x values and find f(x)

x -----> g(x) ----> f(x)

0 -----> 0 ---->9

1 -----> 4 ----> 4

2 -----> 8 ---->-11

3 -----> 4 ---->-36

4 -----> 0 ----> -71

From the table we can see that maximum value of g(x) is 8 and maximum value of f(x) is 9 that is 1 unit higher for f(x) than g(x)

Answer is option D.

Number of people can hold in each car = 10

Solution:

Number of cars in the Blazing Bullet = 6

Total number of people can ride at one time = 60

Number of people can hold at one Bullet car = ?

Let n be the number of people in each car can hold.

Now write a equation to find the number of people in each car.

Number of cars × number of people in each car = Total number of people

⇒ 6 × n = 60

⇒ 6n = 60

Now, solving this equation.

⇒ 6n = 60

Divide both sides of the equation by 6.

$ \Rightarrow\frac{6n}{6} = \frac{60}{6}

$ \Rightarrow n=10

⇒ n = 10

Hence 10 people can hold in each car.

Write 2^8 * 8^2 * 4^-4 in the form 2^n
Eva8 [605]

The given expression 2^8 * 8^2 * 4^-4 can be written in the exponential form 2^n as 2^6.

<h3>What are exponential forms?</h3>

The exponential form is a more convenient way to write repetitive multiplication of the same integer by using the base and its exponents.

<u>For example:</u>

If we have a*a*a*a, it can be written in exponential form as:

=a^4

where

  • a is the base, and
  • 4 is the power.

The power in this format reflects the number of times we multiply the base by itself. The exponent is also known as the index or power. 

From the information given:

We can write 2^8 * 8^2 * 4^-4 in form of 2^n as follows:

\mathbf{= 2^8\times (2^3)^2 \times (2^2)^{-4} }

\mathbf{= 2^8\times (2^6) \times (2^{-8}) }

\mathbf{= 2^{8+6+(-8)}}

\mathbf{= 2^{6}}

Therefore, we can conclude that by using the exponential form, the given expression 2^8 * 8^2 * 4^-4 in the form 2^n is 2^6.
