Y=log(x-3)<br><br>what would be the base?
timurjin [86]
By definition, if :

a^y = b

y = log_a b

<span>We highlight the following elements:

</span><span>a = Base of the logarithm;
b = logarithmand or antilogarithm
y = logarithm</span><span>

Therefore:

</span><span>Note that since the base was not specified, we know that it is equal to 10.
</span>
y = log_a b
y = log_{10} (x-3)
10^y = (x-3)
<span>
Answer:

</span>Base of the logarithm = 10

A family is trying to pick from different shades of paint for their living room. They have narrowed it down to 10 colors: 3 diff
NeTakaya

Answer:

30%

Step-by-step explanation:

A family is trying to pick from different shades of paint for their living room. They have narrowed it down to 10 colors: 3 different blues and 7 different greens. The family decides to just randomly select a color from these. What is the probability they will pick a shade of blue? Choose the answer in percent form. Question 3 options: 50% 100% 70% 30%

First, we need to convert the probability of picking a blue shade into a fraction.

= 3/10

Since this is by 10, we need to times 0.3 (numerator) by 10 (the number of outcomes) Whatever you do to the numerator, you do to the denominator. This means that you also times 10 by 10

This gives you 30/100

Since a percentage is out of 100, you don't need to change anything, just take away the 100 and put a percentage sign.

=30%

Given the triangle below, which of the following is a correct statement?
EleoNora [17]

ANSWER

(A)csc angle C equals 3 over 2

EXPLANATION

The cosecant is hypotenuse over opposite.

\csc(C)  =  \frac{6}{4}

\csc(C)  =  \frac{3}{2}

\csc(B) = \frac{6}{5}

The secant is the hypotenuse over adjacent.

\sec(C)=\frac{6}{5}

\sec(B)  =  \frac{6}{4}

\sec(B)  =  \frac{3}{2}

The only correct choice is A
