Find the missing length to the nearest tenth.<br> Right Triangle<br> 6 m<br> C<br> 16 m

nikitadnepr [17]

Answer:

17.1 meters

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean Theorem.

$a^2+b^2=c^2$

where a and b are the legs and c is the hypotenuse.

6 and 16 are the legs, because they form the right angle. c is the hypotenuse because it is opposite the right angle.

$6^2+16^2=c^2$

Evaluate the exponents.

6^2= 6*6= 36

16^2= 16*16= 256

$36+256=c^2$

Add 36 and 256.

$292=c^2$

Since c is being squared, take the square root of both sides of the equation. The exponent and square root will cancel and leave c by itself

$\sqrt{292} =\sqrt{c^2}$

$\sqrt{292}=c$

$17.0880075=c$

Round to the nearest tenth. The 8 in the hundredeth place tells us to roung the 0 in the tenth place up to a 1.

$17.1=c$

c= 17.1 m

The missing length, or the hyptenuse is 17.1 meters.

Determine whether each set of ordered pairs shown below is from a geometric sequence or from an arithmetic sequence.

daser333 [38]

Using sequences concepts, it is found that:

The set of ordered pairs {(-3, 7.5) , (-2, 10) , (-1, 12.5)} is an arithmetic sequence with equation a(n) = 15 + 2.5d.

The set of ordered pairs {(1, 150) , (2, 112.5) , (3, 84.375)} is a geometric sequence with $a_n = 150(0.75)^{n-1}$ .

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

$a(n) = a(0) + nd$

The sequence {(-3, 7.5) , (-2, 10) , (-1, 12.5)} continues with points (0, 15), (1, 17.5), and so on, hence the first term and the common ratio are given, respectively, by:

a(0) = 15, d = 2.5.

Hence the equation is:

a(n) = 15 + 2.5n.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

For the sequence {(1, 150) , (2, 112.5) , (3, 84.375)}, the first term and the common ratio are given, respectively, by:

$a_1 = 150, q = \frac{112.5}{150} = \frac{84.375}{112.5} = 0.75$

Hence the equation is given by:

$a_n = 150(0.75)^{n-1}$

What is the value of log2 128?

DedPeter [7]

If you get confused by logarithms, here's an easier way to think about this problem: What power of 2 equals 128? Well, we know 2^3 = 8, then 2^4 must equal 16. Doubling every times, we get 2^5 = 32, 2^6 = 64 and 2^7 = 128. So, the value of log₂128 is 7.
