Step-by-step explanation:
You want various combinations of the functions g(a) = -3a+1 and h(a) = 3a³ +4a.
g/hThe functions have no common factors, so their ratio leaves the function expressions unchanged:
[tex]\dfrac{g(a)}{h(a)}=\boxed{\dfrac{-3a+1}{3a^3+4a}}[/tex]
h+gThe like terms are combined when the functions are added.
[tex]h(a)+g(a)=(3a^3+4a)+(-3a+1)=3a^3+(4-3)a+1\\\\=\boxed{3a^3+a+1}[/tex]
g-hSimilarly, the like terms are combined when the functions are subtracted.
[tex]g(a)-h(a)=(-3a+1)-(3a^3+4a)=-3a^3+(-3-4)a+1\\\\=\boxed{-3a^3-7a+1}[/tex]
g·hThe product is found the way products are usually found. Each term of one of the factors is multiplied by each term of the other factor, and these products are summed. You can think of it as repeated application of the distributive property.
[tex]g(a)\cdot h(a)=(-3a+1)(3a^3+4a)=-3a(3a^3+4a)+1(3a^3+4a)\\\\=-9a^4-12a^2+3a^3+4a\\\\=\boxed{-9a^4+3a^3-12a^2+4a}[/tex]

What is the point-slope equation of a line with slope -4 that contains the point
(-2,7)?
A. Y+7 = -4(x-2)
B. y-7 = -4(x - 2)
c. y+ 7 = -4(x + 2)
D. Y-7 = -4(x + 2)
Answer:
y -7 = -4(x + 2) (Answer D)
Step-by-step explanation:
The general point-slope equation is y - k = m(x - h)
If the slope, m, is -4, and the point is (h, k) with h = -2 and k = 7), then we have in this case
y -7 = -4(x + 2) (Answer D)
Find all the zeroes of the equation.
x4-6x2-7x-6 = 0
Zeros of the given equation are {-2, 3, (-1±i√3)/2}
Solution:-As the last term is -6 then, ± 2 , ±3 are possible zeroes.
Try 2:-
[tex]2^4-6*(2)^2-7*2-6=-28[/tex] so 2 is not a zero.
Try 3:-
[tex]3^4-6*(3)^2-7*3-6=0[/tex] so 3 is a zero.
[tex](-2)^4-6*(-2)^2-7*(-2)-6=0[/tex] so -2 is also a zero.
Divide the function by (x +2)(x - 3), that is [tex]x^2 - x - 6[/tex]
gives [tex]x^2 + x + 1[/tex]
[tex]x^2 + x + 1[/tex]
So we have [tex]x^2 + x + 1 = 0[/tex]
[tex]x = [-1 +\sqrt{1^1 - 4*1*1}] / 2[/tex]
= -1 + √(-3) / 2 , - 1 - √(-3) / 2.
= -0.5 + 0.866i, -0.5 - 0.866i

Answer:
The domain is the set of numbers that the x value can be.
In an equation like the domain is all real numbers because x can be any number.
In the case of , any x value that is less than or equal to -4 will not work because you would be taking the square root of a negative number, which doesn't work unless you're graphing on a complex plane, which I assume you aren't.

Step-by-step explanation:
A book claims that more hockey players are born in January through March than in October through December. The following data show the number of players selected in a draft of new players for a hockey league according to their birth month. Is there evidence to suggest that hockey players' birthdates are not uniformly distributed throughout the year? Use the level of significance .
Complete question :
Birth Month Frequency
January-March 67
April-June 56
July-September 30
October-December 37
Answer:
Yes, There is significant evidence to conclude that hockey players' birthdates are not uniformly distributed throughout the year.
Step-by-step explanation:
Observed value, O
Mean value, E
The test statistic :
χ² = (O - E)² / E
E = Σx / n = (67+56+30+37)/4 = 47.5
χ² = ((67-47.5)^2 /47.5) + ((56-47.5)^2 /47.5) + ((30-47.5)^2/47.5) + ((37-47.5)^2/47.5) = 18.295
Degree of freedom = (Number of categories - 1) = 4 - 1 = 3
Using the Pvalue from Chisquare calculator :
χ² (18.295 ; df = 3) = 0.00038
Since the obtained Pvalue is so small ;
P < α ; We reject H0 and conclude that there is significant evidence to suggest that hockey players' birthdates are not uniformly distributed throughout the year.

Answer:
about 75.36
Step-by-step explanation:
we know the radius of the base (circle) is 2 since 4/2 is 2.
Area of cylinder is height times area of base
6*4π=24π
You round π as 3.14
so 3.14*24= 75.36
Answer:
[tex] 75.4 \: {cm}^{3} [/tex]
Step-by-step explanation:
Height of the cylinder h = 6 cm
Diameter d = 4 cm
Radius r = 4/2 = 2 cm
[tex]V_{cylinder} = \pi {r}^{2} h \\ \\ = 3.14 \times {(2)}^{2} \times 6 \\ \\ = 3.14 \times 4 \times 6 \\ \\ = 3.14 \times 24 \\ \\ = 75.36 \\ \\ = 75.4 \: {cm}^{3} [/tex]

In rolling two dice, what is the probability that the sum of the two numbers on the dice will be 4?
A: 1 over 12
B: 3
C: 11 over 12
D: 2 over 3
Answer:
A
Step-by-step explanation:
If the dice are fair and 6 sided then you can roll a 4 in three ways
2 2
1 3
3 1
The total number of ways you can throw two 6 sided dice is 6 * 6 or 36
So P(4) = 3/36 = 1/12

how much do 10 pieces of candy cost if 1000 pieces cost $40
The residual value of the car is estimated to be $13,650. The lease has no termination fees or charges. If you decide to purchase, your bank requires a down payment of $3,800 and will finance the balance with a 10.25% APR loan for 36 months. The sales tax in your state is 6.5%, and the tag and title charges are $75. The opportunity cost is the interest your down payment could have earned if you didn’t purchase the vehicle. Currently, your money earns 4.5% in a savings account.

C: (0,-5), (5,0)
D: (0,-1), (2,-5)
Answer:
(1, -4), (4, -1)
Step-by-step explanation:
A solution to a system of equations is when the two lines intersect. In this case, we have two intersections, which means two solutions.
From left to right, we first see an intersection at (1, -4).
Continuing to the right, we see another intersection at (4, -1)
These are our two solutions.

Compute the MIRR statistic for project I if the appropriate cost of capital is 11 percent.
Cash flow -12,000, 5830, 4680, 2,500
The MIRR statistic for the project I given the cost of capital and the reinvestment rate, is 7. 43 %.
How to find the MIRR statistic ?A monetary indicator of an investment's allure is the modified internal rate of return or MIRR. Ranking equivalent alternative investments is done in capital budgeting.
You can use a spreadsheet to find the MIRR by first ordering the cash flows as shown in the attached image. Then use the = MIRR function.
The cost of capital is the finance charge which is 11 %. The reivestment rate will be the same as the finance charge if not given so it will be 11 % as well.
The MIRR is therefore 7 .43 %.

What are coefficients and like terms?A quantity or number that is combined with a variable is known as a coefficient. The variable is often multiplied by an integer, which is then printed next to it.
Terms that have the same variables raised to the same power are referred to as like terms. The only difference is in the numerical coefficients.
We know a coefficient is a constant value combined with a variable.

. How many four letter patterns can be formed using the letters A, B, and C if letters may be repeated?
Answer:
24 patterns
Step-by-step explanation:
Given that four lettered patterns are to be formed using the three alphabets. Since letters may be repeated, then;
4[tex]P_{3}[/tex] = [tex]\frac{4!}{(4 - 3)!}[/tex]
= [tex]\frac{4 x 3 x 2!}{1!}[/tex]

4[tex]P_{3}[/tex] = 24
Therefore, 24 four letter patterns can be formed when the given letters are repeated.
Evaluate the expressions 56 with a variable of -1
Answer:
The expression 56 with a variable of -1 is not well defined. The term 56 is a constant number, and the variable of -1 is also a constant. Therefore there is nothing to evaluate.
Step-by-step explanation:
If you want to evaluate the expression 56*(-1) it would give -56 as output because -1 is a scalar and multiplying with a scalar will change the sign of the constant 56 but it won't change its value.
In other words, to evaluate an expression, it needs to have a mathematical operation or function, operands, and/or variables that can be replaced with values or expressions. Without any operation, there's nothing to evaluate.
