Mathematics

Effectus [21]3 years ago

Answer:

x = 40

Step-by-step explanation:

Given 2 secants to a circle from an external point, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

8(8 + x) = 12(12 + 20) ← distribute parenthesis on both sides

64 + 8x = 12 × 32 = 384 ( subtract 64 from both sides )

8x = 320 ( divide both sides by 8 )

x = 40

In order to answer the question, what we really need from the given is that there are 480 copies of books and they arrived in 5 cartons. To determine the number of books in each carton, we just have to divide 480 by 5 which gives us an answer of 96. </span>

Which expression both gives the average rate of change of the function h(x)
liubo4ka [24]

Answer:

D

Step-by-step explanation:

The average rate of change of a function over an interval a ≤ x ≤ b is found by:

\frac{f(b)-f(a)}{b-a}

Here, a is 0 and b is 3, so: \frac{f(3)-f(0)}{3-0}=\frac{f(3)-f(0)}{3}

Just plug in 3 for the first term and 0 for the second term in the numerator:

- First term: \frac{1}{2} (3^{3+\frac{1}{2} })+3=\frac{1}{2} (3^{3\frac{1}{2} })+3

- Second term: \frac{1}{2} (3^{0+\frac{1}{2} })+3=\frac{1}{2} (3^{\frac{1}{2} })+3

So, the final answer is:

\frac{[\frac{1}{2} (3^{3\frac{1}{2} })+3]-[\frac{1}{2} (3^{\frac{1}{2} })+3]}{3}

Thus, the answer is D.

Hope this helps!
