Answer:
first option
Step-by-step explanation:
To find the product, that is
(4x + 1)(x² - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(x² - 5) + 1(x² - 5) ← distribute both parenthesis
= 4x³ - 20x + x² - 5
= 4x³ + x² - 20x - 5

I still don't get how to do this: Solve for t then simplify your answer. -6/5t=9
Answer:
t= -15/2 or t= -7.5
Step-by-step explanation:
We are given the equation:
[tex]\frac{-6}{5}t=9[/tex]
and asked to solve for t. Therefore, we must isolate t on one side of the equation.
t is being multiplied by -6/5. The inverse of multiplication is division. We should divided both sides by -6/5, but we are dividing by a fraction. Instead, we can multiply by the reciprocal.
To find the reciprocal, flip the numerator (top number) and denominator (bottom number).
-6/5 ----> -5/6
Multiply both sides of the equation by -5/6
[tex]\frac{-5}{6} *\frac{-6}{5}t=9 *\frac{-5}{6}[/tex]
[tex]t=9 *\frac{-5}{6}[/tex]
[tex]t=\frac{9}1 *\frac{-5}{6}[/tex]
Multiply across the numerator and denominator.
[tex]t= \frac{9*-5}{1*6}[/tex]
[tex]t=\frac{-45}{6}[/tex]
Simplify the fraction. Both the numerator and denominator can be divided by 3.
[tex]t=\frac{-45/3}{6/3}[/tex]
[tex]t=\frac{-15}{2}[/tex]
[tex]t= -7.5[/tex]
t is equal to -15/2 or -7.5

A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors. What is the number of possible outcomes? a.14 b.40 c.44 d.104
Answer:
40
Step-by-step explanation:
Given that:
Number of options available for transmission = 2 (Standard or Automatic)
Number of options for doors = 2 (2 doors or 4 doors)
Number of exterior colors available = 10
To find:
Total number of outcomes = ?
Solution:
First of all, let us calculate the number of outcomes for the transmission mode and number of doors options.
1. Standard - 2 doors
2. Standard - 4 doors
3. Automatic - 2 doors
4. Automatic - 4 doors
Number of outcomes possible = 4 (which is equal to number of transmission mode available multiplied by number of doors options i.e. 2[tex]\times 2[/tex])
Now, these 4 will be mapped with 10 different exterior colors.
Therefore total number of outcomes possible :
Number of transmission modes [tex]\times[/tex] Number of doors options [tex]\times[/tex] Number of exterior colors
2 [tex]\times[/tex] 2 [tex]\times[/tex] 10 = 40
The number of possible outcomes of a new car will be 40. Then the correct option is B.
What is a sample?A sample is a collection of well-defined elements. A sample is represented by a capital letter symbol and the number of elements in the finite sample is shown as a curly bracket {..}.
A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors.
Then the number of possible outcomes will be

A farmer has some chickens and rabbits. There are 60 eyes and 100 legs altogether. How many chickens and how many rabbits are there?
Answer:
20 rabbits, 10 chickens
Step-by-step explanation:
Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.
Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.
So the extra (100 – 60) = 40 legs must have come from the rabbits.
Every rabbit has (4 – 2) = 2 more legs than a chicken.
So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.
Answer:
20 rabbits and 10 chicks

What is the length of the x-component of the vector shown below?
Answer:
13.91
Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached.
From the diagram the length of the vector along x component is given as:
Vx = Vcos(theta)
theta is the angle between the vector and the x axis
V is the length of the vector
Given
theta = 22°
V = 15
Substitute the given values into the formula above
Vx = 15cos22°
Vx = 15×0.9272
Vx = 13.91
Hence the length of the x-component of the vector is approximately 13.91
5.5% of x =19.84
find x
Answer: 360.73
Step-by-step explanation:
When you come across any question that says [a of b] is just saying a × b.
5.5% of x=5.5% × x
-----------------------------------------------------------------
Given
5.5% of x=19.84
Converted into numerical expression
5.5% × x=19.84
Divide both sides by 5.5% (0.055)
x=19.84 ÷ 5.5%
simplify
x=360.73 (rounded)
Answer:
360.7273
Step-by-step explanation:
5.5% of 'x' is 19.84
so, x*5.5/100 = 19.84
or, x*5.5 = 1984
or, x = 1984/5.5
so, x=360.7273(answer)

2(x – 7) = 5x + 4 can someone help me out
Answer:
x = -6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2(x - 7) = 5x + 4
Step 2: Distribute parenthesis
2x - 14 = 5x + 4
Step 3: Subtract 2x on both sides
-14 = 3x + 4
Step 4: Subtract 4 on both sides
-18 = 3x
Step 5: Divide both sides by 3
-6 = x
Step 6: Rewrite
x = -6
Answer:
x=-6
Step-by-step explanation:
2(x-7)= 5x+4
2x - 14 = 5x+4
-2x -2x
-14 = 3x +4
- 4 -4
-18= 3x
18/3 = 3x/3

Answer:
The line that can be drawn through points D and E is contained in plane Y.
Step-by-step explanation:
Let's just go through all of these answer choices.
The first one says that "The line that can be drawn through points C and D is contained in plane Y." Is this true? If we drew a line connecting points C and D, it looks like it would cross through both planes X and Y, so it cannot be contained in only plane Y. This is false.
The second one says that "The line that can be drawn through points D and E is contained in plane Y." If we imagine a straight line going from point D to point E, it looks like it's just a line in plane Y; so this can be contained in plane Y. This seems true.
The third one says that "The only point that can lie in plane X is point F." This is false because plane X has a ton of points, but point F is just the only one that's labeled. This is false
The fourth one is similar, and says that "The only points that can lie in plane Y are points D and E." Again, this is false because points D and E just happen to be the only two labeled points, but there are infinitely many points on plane Y; points D and E are not all of them.
The second answer choice is true.

What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
The equation of the straight line from the given graph can be formed as below,
Take any two coordinates from the graph as (1, 10) and (2, 25) respectively.
Suppose the cost be y and the number of pajamas be x.
Now, the equation for the slope can be written as,
(y - 10)/(x - 1) = (25 - 10)/(2 - 1)
⇒ (y - 10)/(x - 1) = 15
⇒ y = 15x - 5.
Then, the cost of 6th pajama can be calculated by substituting x = 6 in the above equation as,
y = 15 × 6 - 5
= 85
Hence, the cost of sixth pair of pajama is $85.

Jim was offered a job as a computer programmer making 65K per year. Another company offered Jim a position earning $1,800 a week. What job pays more?
Answer:
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more
Step-by-step explanation:
To check what job pays more we have to compare yearly salary of both the company offer.
_________________________________________________
Yearly salary from one company = 65k = 65000
Weekly salary from another company = $1800
there are 52 weeks in a year
to get yearly salary , we need to multiply weekly salary with 52.
Yearly salary from another company = Weekly salary*no of wees in a year
Yearly salary from another company = 52*$1800 = $93,600
since second company salary, $93,600, is more than first company yearly salary of $65000
Second company pays more

The graph shows the function representing the recommended amount of mulch, in cubic yards, for circular flowerbeds based on the radius of the flowerbed in feet. If the vertex of the function is at the point (0, 0.5), what is the recommended amount of mulch for a flowerbed with a radius of 20 feet? Round to the nearest tenth if necessary. 7 cubic yards 13 cubic yards 25.5 cubic yards 31 cubic yards
Answer:
B, 13 cubic yards.
Step-by-step explanation:
You didn't give a graph, but I'm assuming you had the same question as me (I attached the graph that I had). I took the test and got the right answer.
The recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards
How to determine the recommended amount of mulch?The vertex of the graph is given as:
Vertex = (0,0.5)
The equation of the graph is given as:
[tex]y = 0.5 * 1.177^x[/tex]
When the radius is 20 feet, we have:
y = 0.5 * 1.177²⁰
Evaluate
y = 13.02
Approximate
y = 13.0
Hence, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards
