Find 4.5×10^7 over 1.5×10^-8 . write answer in scientific notation.

Sati [7]

Answer:

$\large\boxed{\dfrac{4.5\times10^7}{1.5\times10^{-8}}=3\times10^{15}}$

Step-by-step explanation:

The scientific notation:

$a\times10^k\ \text{where}\ 1\leq a$

We have:

$\dfrac{4.5\times10^7}{1.5\times10^{-8}}=\dfrac{4.5}{1.5}\times\dfrac{10^7}{10^{-8}}$

Use

$\dfrac{a^n}{a^m}=a^{n-m}$

$=3\times10^{7-(-8)}=3\times10^{7+8}=3\times10^{15}$

In the function f(x) = a(x + 2)(x-3)^b, a and b are both

Gekata [30.6K]

Using limits, considering the end behavior of the function f(x), it is found that the correct statement is given as follows:

D. a is positive, and b is odd.

<h3>What is the end behavior of a function?</h3>

It is given by it's limits as x goes to negative and positive infinity.

In this problem, we have that, considering the end behavior:

$\lim_{x \rightarrow \infty} = \infty \rightarrow ax^{b + 1} = \infty$

$\lim_{x \rightarrow -\infty} = \infty \rightarrow ax^{b + 1} = \infty$

This will only be true if a is positive and b is odd, hence option D is correct.

Ede4ka [16]

Answer:

Do the side lengths 14, 48, and 50 make a right triangle ?

Yes !

Step-by-step explanation:

right triangle (Pithagora)=>

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500 (true)

THis table gives a few (x, y) pairs of a line in the coordinate plane.

Mashcka [7]

Answer:

The x-intercept is : (22, 0)

Step-by-step explanation:

Given the table

x y

48 30

61 45

74 60

From the table, it is clear that every y value is changing 15 units, and every x is changing 13 units. Hence, it is a straight line.

Hence, we can find the other values of this straight line as well.

When the value of y = 15 i.e. (30-15), then the value of x will

be 35 i.e. (48 - 13).

y = 30 - 15 = 15, and x = 48 - 13 = 35.

Similarly,

When the value of y = 0 i.e. (15-15), then the value of x will be 22 i.e. (35-13).

y = 15-15 = 0, and x = 35 - 13 = 22.

As we know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.

so, as we have checked that when the value of y = 0, then the value of x = 22.

Therefore, the x-intercept is : (22, 0)
