A. x + 64
B. x + 4y
C. y5+ 13x +12
D. A + 3y2 + 2y
E. x
F. x(10-2) + 7
SUBMIT
Answer: C, y^5 + 13x + 12
Step-by-step explanation:
A trinomial is a polynomial that consists of three terms. y^5 is one term, 13x is the second, and 12 is the third term. Each term is separated by an operator (ie +,-,*, etc). Constant terms are terms that do not change. In this case, your constant term is 12.
Answer:
C
Step-by-step explanation: A trinomial has 3 terms and a constant term is just a number.

Big Ben is the largest clock tower in England and overlooks the Houses of Parliament and the Thames River. The minute hand of the clock measures 36 feet in length. How far does the tip of the minute hand move in 20 minutes
Answer:
75.408 ft
Step-by-step explanation:
In 20 minutes, the angle swept by a minute hand is calculated as
(20/60) x 360° = 120°
The length of the minute hand = 36 ft
To calculate the distance moved by the minute hand, we solve for the fraction of the circumference of a circle swept by the minute hand in going through this 20 min.
we use the expression
Distance moved by the tip of the minute hand d = (θ/360) x 2πR
where
θ is the angle swept in the 20 minutes = 120°
R is the length of the minute hand, which is the radius of the circle formed if the minute hand moves completely in a 360° motion round the clock.
R = 36 ft
substituting values, we have
d = (120/360) x (2 x 3.142 x 36) = 75.408 ft
The tip of the minute hand moves 0.21 ft in 20 minutes.
Length of an arc
The minute hand sweeps an arc of length L given by
L = Ф/360° × 2πR where
Ф = angle moved by minute hand in 20 minutes = 20' × 1°/60' = 1/3° and R = length of minute hand = 36 ftDistance moved by tip of minute handSo, substituting the values of the variables into the equation, we have
L = Ф/360° × 2πR
L = 1/3°/360° × 2π × 36 ft
L = 1/(3 × 360) × 2π × 36 ft
L = 1/(3 × 10) × 2π ft
L = 1/30 × 2π ft
L = 1/15 × π ft
L = 3.1416/15 ft
L = 0.2094 ft
L ≅ 0.21 ft
So, the tip of the minute hand moves 0.21 ft in 20 minutes.

What is 7/8- 5/8?
Answer
Answer:
1/4
Step-by-step explanation:
Since the denominatior is the same, we can look at only the numerator. So 7/8 - 5/8 is basically 7 - 5 which is 2.
The denominator doesn't change so it's 2/8. We can further simplify this into 1/4.

Which graph represents the solution to the compound inequality? 4x + 8 < –16 or 4x + 8 ≥ 4 A number line with an open circle at negative 6 with a bold line pointing to the right ending at the point at negative 1. A number line with a point at negative 6 with a bold line pointing to the right ending at the open circle at negative 1. A number line with an open circle at negative 6 with a bold line pointing to the left. A point at negative 1 with a bold line pointing to the right. A number line with a point at negative 6 with a bold line pointing to the left. An open circle at negative 1 with a bold line pointing to the right.
Answer:
a line starting at -6 going to the left of this number, and with an open circle around the -6.
Step-by-step explanation:
To solve for this inequality, we need to isolate "x" on one side of the inequality symbol (<):
4 x + 8 < -16
subtract 8 from both sides:
4 x < -16 - 8
4 x < - 24
now divide both sides by 4 to get rid of the 4 that appears multiplying "x":
x < - 24/4
x < - 6
To graph this inequality one needs to highlight all the real numbers of the number line to the left of the value -6, making sure that one draws an open circle around the -6 because we don't want this number to be included (notice that x < -6 implies x-values strictly smaller than -6)
Then one would draw a line starting at -6 going to the left of this number, and with an open circle around the -6.

The travelers are adding a new room to their house. the room will be a cube with volume 3375 ft.³.they are going to put in hardwood floors, the contractor charges $10 per square foot. how much will the hardwood floors cost?
Answer:
$ 2250
Step-by-step explanation:
3375 = s³
s = ∛3375
s = 15 ft.
floor area = s² = (15 * 15)
floor area = 225 ft²
the contractor charges $10 per ft².
therefore,
the hardwood cost = 225 x $10 = $2250
Answer:
$2,250.
Step-by-step explanation:
So first, we need to find the area of the floor (the side shaded green). To do so, we first need to find the length of the one side of the room.
Since we know that the room is a cube, all side lengths are equivalent. And since we are given that the volume of the room is 3375, we can find the length of the side.
The volume of a cube is given by the formula:
[tex]V=s^3[/tex]
Substitute 3375 for V:
[tex]s^3=3375[/tex]
Take the cube root of both sides:
[tex]s=\sqrt[3]{3375}=15[/tex]
So, the side length of the room is 15.
This means that the area of the floor is:
[tex]A=(15)^2\\A=225\text{ in}^2[/tex]
They charge $10 per square foot. There are 225 square feet. Thus, the total cost will be:
[tex]10(225)=$2250[/tex]
$2,250.
find the sum to infinity of a geometric series having a second term of -9 and fifth term of 1/3 g
Answer:
S infinity= -51/4
Step-by-step explanation:
First term
ar= -9
Fifth term
ar⁴= 1/3
Solving for the value of the r and a
ar= -9
ar⁴= 1/3
Dividing each other
r³=1/3 * -1/9
r³=-1/27
r= 3√-1/27
r= -1/3
Solving for a
ar= -9
a(-1/3)= 9
a= 9*-3
a= -27
Sum of a go to infinity is given by the formula
S infinity= a/(1-r)
S infinity= -27/(1-(-1/3))
S infinity= -27/(1+1/3)
S infinity= -27 * 3/4
S infinity= -51/4

Answer:
[tex]4p\geq 12[/tex]
Step-by-step explanation:
So, when there were 4 innings left, the score was 17 to 6 and Kim was losing.
Since the score was 17 to 6, in order for her to win, they must've scored at least another 12 points.
This is because we are told that the other team didn't score, so their final score is 17.
And for Kim to win, they must have more points, so their must've scored at least 12 points for their score to be 18.
And we also know that they scored the same per inning for the next four innings.
Thus, in an inequality, this is:
[tex]4p\geq 12[/tex]
The score per inning times 4 innings must be greater than or equal to 12:
Further notes:
To solve, divide both sides by 4:
[tex]p\geq 3[/tex]
In other words, Kim's team must've scored at least 3 points per inning.
Also note that this solution include only integers, since you can't score 3.5 points.
Solve x(x+9)+12=0 by using the Quadratic Formula.
Answer:
Answer: approximately -1.63 and -7.37
Step-by-step explanation:
First of all, let's expand the parenthesis by multiplying x into both of its terms.
[tex]x(x+9)+12 = 0\\x^2+9x+12=0[/tex]
We get the equation:
[tex]x^2+9x+12=0[/tex]
The quadratic formula looks like this
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
where the equation is of the form
[tex]ax^{2}+bx+c=0[/tex]
Comparing this to our equation above,
[tex]x^2+9x+12=0[/tex]
we can see that
[tex]a = 1\\b= 9\\c= 12[/tex]
Let's put these values into the quadratic formula.
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-9\pm\sqrt{9^2-4*1*12}}{2*1}\\x=\frac{-9\pm\sqrt{9^2-48}}{2}\\x=\frac{-9\pm\sqrt{81-48}}{2}\\x=\frac{-9\pm\sqrt{33}}{2}\\x=\frac{-9\pm\ 5.744...}{2}\\x=\frac{-9\pm\ 5.744...}{2}\\x_{1}=\frac{-9+5.744...}{2}=\frac{-3.255...}{2}=-1.62771867\\x_{2}=\frac{-9-5.744...}{2}=\frac{-14.744...}{2}=-7.3722813\\[/tex]
Answer: approximately -1.63 and -7.37
You can also choose not to approximate the square root of 33, and you'd receive the answers:

Write an absolute value inequality that represents the situation.
The length of a standard basketball court can vary from 84 feet to 94 feet, inclusive.
Answer:
|x - 89| ≤ 5
Step-by-step explanation:
Here the range is 84 to 94 ft, with the midpoint being 89 and the greatest variation from the midpoint being ±5.
We adapt |x| ≤ a as follows: replace x with 'x - 89' and a with 5:
|x - 89| ≤ 5
It is customary to regard '89' as the 'center' of the solution interval and 5 as the 'maximum difference' or 'radius' separating x from this center.

Step-by-step explanation:
Given a right triangle with legs 5cm and 12cm, find the length of the hypotenus. Show work please
Answer:
13 cm
Step-by-step explanation:
We can use the Pythagorean Theorem to find the length of the hypotenuse. The Pythagorean Theorem is used to find a missing side to a right triangle.
The theorem states that [tex]a^2 + b^2 = c^2[/tex], where a and b are the legs, and c is the hypotenuse.
The legs of this triangle are already states - 5 and 12, so we can plug it's values into the formula.
[tex]5^2 + 12^2 = c^2\\\\25 + 144 = c^2\\\\169 = c^2\\\\c = \sqrt{169}\\\\c=13[/tex]
So the hypotenuse of this triangle is 13 cm.

A cylinder has a volume of 320 cubic inches and a height of 5 inches.
What is the radius of the cylinder?
O A. 4 inches
B. 8 inches
C. 16 inches
D. 32 inches
Answer:
The radius is 8 inches
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
Assuming you mean 320 pi for the volume
320 pi = pi r^2 ( 5)
320 =5pi r^2
Divide each side by 5pi
320 pi / 5pi = 5 pi r^2 / 5pi
64 = r^2
Take the square root of each side
sqrt(64) = sqrt(r^2)
8 = r
The radius is 8 inches
Answer:
[tex]\Huge \boxed{\mathrm{4.51 \ inches}}[/tex]
[tex]\rule[225]{225}{3}[/tex]
Step-by-step explanation:
[tex]V=\pi r^2 h[/tex]
The volume is 320 in³.
The height is 5 in.
[tex]320=\pi r^2 * (5)[/tex]
Solving for [tex]r[/tex].
Dividing both sides by 5.
[tex]64=\pi r^2[/tex]
Dividing both sides by [tex]\pi[/tex].
[tex]20.371833=r^2[/tex]
Taking the square root of both sides.
[tex]r= 4.513517[/tex]
The radius is 4.51 inches.

Suppose C = 30y + 15 and y = 40x + 25.
Which of the following is equivalent to C = 30y + 15, but written only in terms of x?
Answer:
d.)
C = 1200x + 765
Step-by-step explanation:
The substitution property of equality allows you to substitute an expression for a variable. Since y equals 40x + 25, you can substitute (40x + 25) for y in the C = 30y + 15 equation:
C = 30y+ 15
y = 40x + 25
C = 30y + 15
C = 30(40x + 25) + 15
C = 1200x + 750 + 15
C = 1200x + 765
The equivalent expression for C = 1200x+765.
C = 30y+15; y = 40x+25 Equivalent relation between C and x to determine.
Equations are defined as the mathematical expression intended meaning to something that contains an equal sign.
Here, C=30y+15
y = 40x+25
Putting y in C = 30y+15
C= 30(40x+25)+15
C = 1200x + 750 +15
C = 1200x +765
Thus, the equivalent expression for C = 1200x+765.
