The illustration below is a graph of the polynomial function P(x). The graph crosses the x-axis 2 times and touches the x-axis o

Anastaziya [24]

The polynomial graph crosses the x-axis at two points and touches x-axis at one point. It indicates the graph has four roots:

$x=-1.5$
$x=-2$
$x=4$
$x=4$

The last two roots have equal value as the graph touches the x-axis (not crosses it)

The graph has three unique roots

The roof of a new sports arena rests on round concrete pillars. The maximum load a cylindrical column of a circular cross sectio

KATRIN_1 [288]

Answer: There are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Step-by-step explanation:

Since we have given that

Height of columns of arena = 9 m

Diameter = 1 m

Load = 14 metric tons

Since Load is directly varies as the fourth power of the diameter 'd', and inversely as the square of the height.

so, Mathematically, it is expressed as

$L=\dfrac{kd^4}{h^2}\\\\14=\dfrac{1.k}{9^2}\\\\14\times 81=k\\\\k=1134$

If the height of columns = 8 m

Diameter = $\dfrac{2}{3}\ m$

So, Load would be

$L=\dfrac{1134\times (\dfrac{2}{3})^4}{8^2}\\\\L=3.5\ tons$

Hence, there are 3.5 metric tons will be supported by a column 8 m high and two thirds m in diameter.

Solve the pattern: <br> 15, 17, 32, 49, 81 __ __ ← those are the blank spaces.

stiks02 [169]

Answer:

130 and 211

Step-by-step explanation:

15+17= 32

17+32=49

32+49=81

49+81=130

81+130=211

is y=5^w an exponential function if so state the initial value and the base if not then which type of function is it

Gwar [14]

By using the property of exponential function, the results obtained are

Base of the function is 5.

Initial value of the function is close to zero.

What are exponent?

Exponent tells us how many times a number is multiplied by itself.

For example : In $2^4 = 2\times 2\times 2\times 2$

Here, 2 is multiplied by itself 4 times.

If $a^m = a \times a\times a....\times a$ (m times), a is the base and m is the index.

Here,

$y = 5^w$ is an exponential function.

The base of the function is 5.

As $x \rightarrow -\infty$ , the function tends to 0

So the initial value of the function is close to zero.
