2.) x^2-2x-99 = (x+3) (x-11)
Q3) f(x) 2x^2 - 5x, g(x) = 3x^3 find g(4x)
Answer:
g(4x) = 192x^3
Step-by-step explanation:
For this problem, f(x) is irrelevant since we are simply are dealing with g(x). We will simply replace the value of x in g(x) with 4x. So let's do that.
g(x) = 3x^3
g(4x) = 3(4x)^3
g(4x) = 3(4^3)(x^3)
g(4x) = 3(64)(x^3)
g(4x) = 192x^3
Hence, g(4x) is 192x^3.

Does f(-x) = - f(x)? Why?
Answer:
No
Step-by-step explanation:
-x is only in the parenthesis not outside. Whatever your number is, let's say 2 would be x, you input 2 as x in which you get f(-2)

There are 4 boys and 2 girls from the seventh grade and 3 boys and 5 girls from the eighth grade in the math club. The math club sponsor will randomly pick one student from each grade level to represent the team.
What is the probability that both will be girls?
Answer:
5/24 or 20.8%
Step-by-step explanation:
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
16) The zero of a polynomial ax+b (a is not zero) is
a/b
b/a
-a/b
-b/a
Answer:
x = - [tex]\frac{b}{a}[/tex] ( a ≠ 0 )
Step-by-step explanation:
To find the zero, let the polynomial equal zero, that is
ax + b = 0 ( subtract b from both sides )
ax = - b ( divide both sides by a )
x = - [tex]\frac{b}{a}[/tex]

Answer:
[tex]m\angle CAB=65^\circ[/tex]
Step-by-step explanation:
Angles and Lines
It's convenient to recall two basic principles of angles:
The sum of internal angles in a triangle is 180°
Two linear angles are supplementary, i.e. they sum 180°.
Angles ABC and CBD are linear. Since we know the measure of angle CBD, thus the measure of angle ABC is 180°-6x.
Now focus on the triangle. The sum of its internal angles is:
x + 40 + 3x + 10 + 180 - 6x = 180
Simplifying:
-2x + 230 = 180
Subtracting 230:
-2x = -50
Dividing by -2:
x = -50 / (-2) = 25
x = 25°
Now find the measure of angle CAB
[tex]m\angle CAB=x+40=25+40=65[/tex]

What is the modulus and argument after (StartRoot 3 EndRoot) (cosine (StartFraction pi Over 18 EndFraction) + I sine (StartFraction pi Over 18 EndFraction) ) gets raised to the 6thpower?
ill give brainiest :3
Answer:
On the test I took the correct answer is c
Step-by-step explanation:
I took the test
The modulus= 27 and Argument = π/3
What is Argument?The angle inclining from the real axis in the direction of the complex number shown on the complex plane is known as the argument of a complex number.
Given:
z = √3 (cos (π/18) + i sin (π/18))[tex]^{6[/tex]
Now, z = [tex](\sqrt{3}) ^6[/tex] (cos (π/18) + i sin (π/18))[tex]^{6[/tex]
z = 27 (cos (π/18) + i sin (π/18))[tex]^{6[/tex]
As, A complex equation can be expressed as:
z [tex]= |z |e^{i\theta[/tex]
where z= Modulus and [tex]\theta[/tex] is an argument
and, [tex]e^{i\theta =[/tex] cos (π/18) + i sin (π/18)
Then, z = 27 ([tex]e^{i(\(\pi/18)}^6[/tex])
and [tex]e^{i\theta =[/tex] [tex]e^{i(\(\pi/18)}^6[/tex]
Now comparing
[tex]i\theta =i \pi/18[/tex] x 5
[tex]\theta = \pi/3[/tex]

Which of the following are properties of a perfect square trinomial? Select all
that apply.
A. The first and third terms must be perfect squares.
B. Neither of the perfect
squares can have a minus sign.
C. If the perfect square terms are A2 and B2 then the other term
must be 2 AB or -2AB.
D. None of the above is a property of a perfect square trinomial.
Answer:
C) If the perfect square terms are A^2 and B^2 and other terms must be 2 AB and -2AB
Step-by-step explanation:
As,
[tex](a^2+2ab+b^2)=(a+b)^2\\(a^2-2ab+b^2)=(a-b)^2[/tex]
Answer:
A, B and CStep-by-step explanation:
The Perfect Squares are the squares of the integers
Perfect square trinominal is: a² ± 2ab + b² {which is (a±b)²}
So:
The first and third terms must be perfect squares and neither of the perfect squares can have a minus sign and If the perfect square terms are A2 and B2 then the other term must be 2AB or -2AB
The total cost for tuition plus room and board at State University is 6,584
dollars. Tuition costs 1804 dollars more than room and board. What is the
tuition fee?
Answer:
$4,194
Step-by-step explanation:
First, you need to subtract the 1,804 from the the total, which will give you 4,780. Divide this by two to get the cost of room and board, which is 2390. To find the tuition fee, add 2,390 and 1,804, and that equals $4,194.

Write a quadratic equation with –6 and 5 as its roots.
While there are many quadratic equations using -6 and 5 as roots, the most simple would be the basic (x+6)(x-5)=0, or simplified, x² + x - 30 = 0.
Using these roots, all you have to do is make both sides of the equation and even both sides of the multiplied pre-product to equal 0. If using this format, x has to be equal to -6, and 5.
At the end of a snow storm, Allison saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 20 inches of snow on the lawn when the storm ended and then it started melting at a rate of 1.25 inches per hour. Write an equation for S , S, in terms of t , t, representing the depth of snow on Allison's lawn, in inches, t t hours after the snow stopped falling.
Answer:
S=20-1.25t
Step-by-step explanation:
I got this answer welcome.
The equation for depth of snow after t hours is, S = 20 - 1.25 t.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
The initial depth of snow = 20 inches,
Rate of melting = 1.25 inches per hour.
After t hours, the snow melt = 1.25 t
The equation of the S in terms of t can be written as,
S= 20 - 1.25 t.
The required equation is S = 20 - 1.25 t.
