A) quintic monomial
B) constant trinomial
C) constant monomial
D) quadratic monomial
Answers
Answer:
Constant monomial
Step-by-step explanation:
Monomial means that there is only one term, so constant trinomial cannot be correct.
Quintic monomials have a degree of 5 and quadratic monomials have a degree of 4, but this has a degree of zero, so this must be a constant monomial.
I hope this helps you. Have a nice day.
In how many ways can 5 people arrange themselves in a row for picture taking ?
Answers
Answer:
120 times
Step-by-step explanation:
There are 5 people to fill the first place, 4 remaining to fill the second, 3 remaining to fill the third, 2 remaining to the fourth place and only 1 remaining to fill the fifth. That means there are 5 factorial (5!) ways. 5! = 5 x 4 x 3 x 2 x 1 = 120.
Write the equation in standard form for thelcircle with center (-8, -1) and radius 4
Answers
9514 1404 393
Answer:
(x +8)^2 +(y +1)^2 = 16
Step-by-step explanation:
The standard form equation for a circle with center (h, k) and radius r is ...
(x -h)^2 + (y -k)^2 = r^2
For your center and radius, the equation is ...
(x -(-8))^2 +(y -(-1))^2 = 4^2
(x +8)^2 +(y +1)^2 = 16

Amir subtracted a quantity from the polynomial 3x² + 8x - 16 and produced the expression x^2- 4. What quantity did Amir subtract? Explain how
you got your answer.
Answers
Answer:
[tex]2x^2+ 8x -12[/tex]
Step-by-step explanation:
Given
[tex]P = 3x^2 + 8x - 16[/tex]
[tex]Result = x^2 - 4[/tex]
Required
The quantity subtracted
Let the subtracted quantity be Q. So, we have:
[tex]P - Q = Result[/tex]
[tex]3x^2 + 8x - 16 - Q = x^2 - 4[/tex]
Collect like terms
[tex]Q = 3x^2 - x^2+ 8x - 16 + 4[/tex]
[tex]Q = 2x^2+ 8x -12[/tex]
The quantity subtracted is: [tex]2x^2+ 8x -12[/tex]
Write an inequality for the following problem. Use X as your variable. 10 less than 7 times a number is greater then 56.
Answers
Answer:
7x -10 > 56
Step-by-step explanation:
For this you simply write what the sentence states. Ten less means you are subtracting 10 from 7 times a number, x. So, 7x -10. The statement also says this is greater than 56, so put >56, for 7x-10>56.

If AC=22 BC=19 in a figure what is the radius?
Answers
Answer:
11.09units
Step-by-step explanation:
Find the diagram attached
The radius of the circle is line projecting from the center to the circumference. Hence AB is the radius of the circle.
To get AB, we will use the pythagoras theorem as shown;
Given
AC=22
BC=19
AC² = AB²+BC²
22² = AB²+19²
AB² = 22²-19²
AB² = 484-361
AB² = 123
AB = √123
AB = 11.09
Hence the radius of the circle is 11.09units

On Monday, 248 students went on a trip to the zoo. All 6 buses were filled and 8 students had to travel in cars. How many students were in each bus?
Answers
Answer:
40 students in each bus.
Step-by-step explanation:
Subtract the 8 extra students from the total to get the total number of students who rode in buses. Then divide that total by 6.
248-8=240
240/6=40
40 students in each bus.
240/6=40
= 40 students in all six buses

Step-by-step explanation:
It looks like every time the coefficient increases by 3 while the exponent increases by 1.
[tex]\\45\\\sum 3(n+1)x^{n}\\n = 0[/tex]
Notice it starts at zero so 3 is multiplied by (x+1) to make it start from 0
The exponent is simply n, because at the start is it zero [tex]x^0=1[/tex], then 1, then 2, so on.
The upper limit is 45 because 45 - 0 = 45 terms

Answer:
351.9 m²
Step-by-step explanation:
[tex]SA=2\pi r^2+2\pi rh[/tex] where r is the radius of the base and h is the height of the cylinder
We're given the diameter of the base, which is 8 m. Therefore, the radius is 4 m (after dividing by 2).
Plug in 4 as r and 10 as h
[tex]SA=2\pi (4)^2+2\pi (4)(10)\\SA=2\pi (16)+2\pi (40)\\SA=32\pi +80\pi \\SA=112\pi[/tex]
Therefore, the surface area of the cylinder is approximately 351.9 m² after rounding to the nearest tenth.

You are designing the garden of your dream and you are going to start with a blank canvas. That means killing everything before putting down new plants. To do this, you are going to use herbicide to kill the overgrown weed. You have a lot of land that measures 22.5 yard by 20.4 yard. Each bottle of herbicide holds 12 fluid oz (fl oz). The instruction says to mix 1.1 fl oz with 1.0 gallon of water and that will treat an area of 155 ft2. How many bottles of herbicide will you need
Answers
Answer:
2.5 bottles or 3 bottles
Step-by-step explanation:
Given that :
Dimension of lot :
22.5 yds by 20.4 yds
Area of lot = 22.5 * 20.4 = 459 yd²
Volume per bottle of herbicide = 12 fl oz
1.1 fl oz combined with water treats an area of 155 ft²
Number of 1.1 fl oz from 12 fl oz that can be obtained : 12 / 1.1 = 10.90
1 yard² = 9 feet²
459 yard² = (459 * 9) = 4131 feet²
Number of 151 feet² that can be obtained from 4131 feet²
4131 feet² / 155 ft²
= 27.3576 times
= 27.3576 / 10.909
= 2.507
This means he'll have to buy a minimum of 3 bottles if a fraction of a bottle can't be purchased.

1. y=x + 3
2. y= 3x + 13
3. y=3x + 1
4. y= -3x + 5
Answers
Given:
Slope of a line = 3
Line passes through the point = (2,7)
To find:
The equation of the line.
Solution:
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope of the line.
The line passes through the point (2,7) and slope of the line 3. So, the equation of the line is:
[tex]y-7=3(x-2)[/tex]
[tex]y-7=3x-6[/tex]
[tex]y=3x-6+7[/tex]
[tex]y=3x+1[/tex]
Therefore, the correct option is 3.

Option 2) dogs 2 to cats 5 | 2/5 = 20/x | .40 = 20/x | .40x = 20 | x = 50
Option 3) you can look and see that 20 is 10 times more than 2 and therefore infer that x is 10 times more than 5 which is 50
