If f(x) = x + 9 and g(x) = 9x – 4,
which statement is true?
Click on the correct answer.
3 is not in the domain of fºg.
3 is in the domain of fºg.
The true statement is (b) 3 is in the domain of f º g.
How to determine the true statementThe 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.

parallel lines p and q are cut by two non parallel lines m and n as shown in the figure the value of x is ? degrees and the value of y is ? degrees
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.
Point B is a point of tangency. Find the radius r of ⊙C.
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.

This drawing shows an Isosceles triangle. Work out the size of angle a.
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.

What is the equation of the line?
Answer:
Step-by-step explanation:
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

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.

If a car has tires with a radius of 1.5 ft and the tires are spinning at 840 rpm (revolutions per
minute), how fast is the car traveling in mph?
[There are 5280 feet in 1 mile) Round your final answer to 2 decimal places.
Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = [tex]\pi[/tex] × (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= 840 × 9·426
1
1 minute = 7917·84 ft
60 minutes = ?
60 × 7917·84
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
475070·4 × 1
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph
hope this helps! =)
