You have to add and divide for the mean(average) so add all of them up and then divide by 3 :)

Which of the following is equivalent to the expression below?<br> log 3-log 15

Nikitich [7]

Answer:

$C. =log\frac{1}{5}$

Step-by-step explanation:

Formula =======================

<em>consider a and b two real numbers </em>

<em>where a > 0 and b > 0.</em>

$log\frac{a}{b} =loga-logb$

……………………………………………………………

log 3 − log 15

$=log\frac{3}{15}$

$=log\frac{3}{3\times 5}$

$=log\frac{1}{5}$

There s 2 different pictures that need two different answers

pantera1 [17]

Answer:

x = 14.6

x = 6.4

Step-by-step explanation:

Trig identities:

$sin(x)=\dfrac{O}{H} \ \ \ \ \ cos(x)=\dfrac{A}{H} \ \ \ \ \ tan(x)=\dfrac{O}{A}$

where

x = angle
O = side opposite the angle
A = side adjacent the angle
H = hypotenuse

$sin(55)=\dfrac{12}{x}\\\\\implies x=\dfrac{12}{sin(55)}\\\\\implies x=14.6$

$tan(62)=\dfrac{12}{x}\\\\\implies x=\dfrac{12}{tan(62)}\\\\\implies x=6.4$

Time taken by Diana to finish her project is 5 1/3 hours
Gabe took 1 1/4 times as long as Diana, therefore Gabes time will be:
1 1/4 × 5 1/3
=5/4 × 16/3
=20/3
=6 2/3 hours

Paula took 3/4 times as long as Diana, therefore time taken by Paula will be:
3/4 × 16/3
=4 hours

- Hope this helps :)

Determine whether each expression is a polynomial. If it is a polynomial, find the degree and determine whether it is a monomial

dsp73

Given that:

The expressions are $3z−2, 2x^3+x-12, 9b, 9x-2$ .

Solution:

Monomial : It contains single terms.

Binomial : It contains two terms.

Trinomial : It contains three terms.

Polynomial : It contains atleast one algebraic term.

Degree of polynomial : It is highest power of the variable.

$3z-2$ , here z is the variable. So, it is a polynomial with degree 1 and it is a binomial.

$2x^3+x-12$ , here x is the variable with highest power 3. So, it is a polynomial with degree 3 and it is a trinomial.

$9b$ , here b is a constant. So, it is not a polynomial and it is a monomial.

$9x-2$ , here x is the variable. So, it is a polynomial with degree 1 and it is a binomial.
