The true statement is (b) 3 is in the domain of f º g.

The functions are given as:

[tex]f(x) = \sqrt{x + 9[/tex]

g(x) = 9x - 4

The function f º g(x) is calculated using:

f º g(x) = f(x)* g(x)

This gives

[tex]f\ o\ g(x) = \sqrt{x + 9} *(9x - 4)[/tex]

Set the radicand greater to 0

[tex]x + 9 \ge 0[/tex]

Solve for x

[tex]x \ge - 9[/tex]

This means that the domain is greater than or equal to -9

Hence, the true statement is (b) 3 is in the domain of f º g.

At the beginning of the Occupation, the Nazis basically let the Jews go about their business. This all changes in October 1940. Measures are introduced one after the other. Civil servants must sign an official declaration stating whether they are Jewish or not. Just like in Germany earlier on, Jewish civil servants and teachers are fired from their jobs. At the beginning of 1941, all Jews in the Netherlands must register.

The statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.

We have:

A student would like to know what proportion of the text messages she sends is to her best friend.

The number of sample methods she selects =  50 text messages

As the sample consists of the 50 texts she randomly chose from the population of all the texts she sent.

Thus, the statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

For the given triangle the measurement of the angle 'a' is 50 degrees.

Use the definition of isosceles triangle defined as:

A triangle with two equal-length sides is said to be isosceles. An isosceles triangle has equal angles on either side of its equal sides.

In the given triangle:

Two sides are of equal length

One angle is 65 degrees and the other is of 'a' degree.

Since we know that,

For an isosceles triangle,

Two sides and two angles of the opposite side are equal.

Therefore,

The third angle of the triangle is also 65 degrees.

Since we know that,

The sum of the interior angles of a triangle = 180 degrees.

Therefore,

a + 65 + 65 = 180

a = 180 - 130

a = 50 degree

Hence,

The measure of an angle is 50 degrees.

Answer: x=3

Step-by-step explanation:

Since both x axis are the same number, you have a "special case" line here.Your line is perfectly vertical, and has an infinite (or undefined) slope. It is this way because in the fraction above, it is impossible to divide by zero to find m! In this case, the equation of your line doesn't even use y=mx+b. Instead, the equation of the line is x=3

Answer:

Serena had $32 at the end.

Step-by-step explanation:

They both had x in the beginning.

Bryan donated $258, so now he has

x - 258

Serena donated $234, so now she has

x - 234

Serena now has 4 times as much money as Bryan.

x - 234 = 4(x - 258)

x - 234 = 4x - 1032

-3x = -798

x = 266

They both had $266.

$266 - $234 = $32

Answer:

Step-by-step explanation:

x+102+115+(180-115)=360

x+282=360

x=78 degrees

y=115 degrees

Answer:

x = 78

y= 115

Step-by-step explanation:

On the angle where p and m meet, we have congruent angles that both equal 102 degrees. The adjacent angles will add up to 180 degrees on a line. So, to find the missing angle, do this:

180-102 = 78 degrees

x is equal to the top right angle where p meets m as they are congruent.

x = 78

You can find y by realizing that the given angle on q meets n are congruent angles. If this angle equals 115 degrees, then y must also equal 115 degrees.

Since Point B is a point of tangency, there is a right angle being created on the edge of that circle.

This means that the Pythagorean Theorem can be applied to solve for r.

[tex]a^2+b^2=c^2[/tex]

[tex]r^2+24^2=(16+r)^2[/tex]

*A common mistake here is distributing the square to both 16 and r, whereas you should be multiplying 16+r by itself (FOIL).*

[tex]r^2+576=r^2+32r+256[/tex]

The [tex]r^2[/tex]s cancel.

[tex]32r+256=576[/tex]

[tex]32r=320[/tex]

[tex]r=10[/tex]

The radius r of Circle C is 10.
