A tree diagram can be drawn. Since we are not concerned with any result of a head on the coin, we can ignore the branches with heads. To find the probability of the results along the branches, we multiply them, giving rise to the answer 1/32.

Use the laws of logarithms and the values given below to evaluate the logarithmic expression (picture provided)
nydimaria [60]

Answer: Option a.

Step-by-step explanation:

To solve the given exercise, you must keep on mind the law of logarithms shown below:

 log(a)-log(b)=log(\frac{a}{b})

Therefore, by applying the law , you can rewrite the expression given, as following:

log(\frac{5}{7})=log(5)-log(7)

You know that:

log5=0.6990\\log7=0.8451

Then, when you substitute values, you obtain:

0.6990-0.8451=-0.1461

A roofer leaned a 16 foot ladder against a house if the base of the ladder is 5 feet from the house how high up the house does t
valkas [14]

Answer:

15.2 feet

Step-by-step explanation:

We use Pythagorean Theorem to find the height.

The hypotenuse of the formed triangle =  length of ladder = 16 feet

base = 5 feet

let h = height of house

16 ^2 = 5^2  +  h^2

256 = 25 + h^2

231 = h^2

h = root(231) = 15.1986 feet

For f(x)=x^2,sketch the graph of g(x)=f(-5x+10)
DiKsa [7]

The graph of g(x) = f(-5x+10) is given in the figure.

<h3>What is a graph?</h3>

A diagram showing the relation between two variable quantities,each measured along one of a pair of axes at right angles.

It is given that f(x) = x^2

and g(x ) = f(-5x+10)

Now putting the value of f(x) in g(x) we get,

g(x)  = f(-5x+10)  = (-5x+10)^2

So, g(x) = (-5x+10)^2

now, making the table for g(x),

<u><em>x </em></u><u>g(x)</u>

0 100

1 81

2 0

3 25

4 100

5 225

Hence,the graph of g(x) = f(-5x+10) is given in the figure.
