Answer:
[tex]\frac{4}{21}[/tex]
Step-by-step explanation:
In order to find the answer you need to find the common denominator of the two fractions multiply the fractions to receive that common denominator and then subtract to find your answer.
[tex]\frac{1}{3} -\frac{1}{7}[/tex]
Find the common denominator:
[tex]CD=21[/tex]
[tex]1\times7=7[/tex]
[tex]3\times7=21[/tex]
[tex]=\frac{7}{21}[/tex]
[tex]1\times3=3[/tex]
[tex]7\times3=21[/tex]
[tex]=\frac{3}{21}[/tex]
[tex]\frac{7}{21} -\frac{3}{21}[/tex]
Subtract numerators
[tex]7-3=4[/tex]
[tex]=\frac{4}{21}[/tex]

Answer:
sending love to you that work is hard
Answer:
Assuming that the multiplicities of the five aforementioned roots ( {0, 5, 1, 3i, -3i} ) are each 1, the 6th zero can be any real number.
Step-by-step explanation:
Because P(X) has real coefficients, and 3i is a zero, we conclude that -3i is also a zero of P(X). Assuming that the multiplicities of the five aforementioned roots ( {0, 5, 1, 3i, -3i} ) are each 1, the 6th zero can be any real number.

An opaque bag contains 27 yellow marbles and 9 teal marbles. If two marbles are randomly chosen from the bag at the same time, find the probability that both marbles are teal. Round your answer to four decimal places.
Answer:
1 out of 9
Step-by-step explanation:
I did this on khan academy a minute ago
Probability that both marbles are teal is 0.0571
What is probability ?Probability is a field of mathematics concerned with numerical representations of the likelihood of an event occurring or a statement being true.
What is the probability that both marbles are teal ?Using the given informationNumber of yellow marbles = 27
Number of teal marbles = 9
Two marbles are drawn randomlyProbability that both marbles are teal

Find the sides of a rectangle whose area is given as x2 +15x +56.
x^2 + 15x + 56
Good way to factor quadratic functions:
In a function x^2 +bx + c
Find two number that when multiplied together will form c (in our case 56) and that when added together form b (in our case 15)
Number 1 x Number 2 = 56
Number 1 + Number 2 = 15
Number 1 = 8
Number 2 = 7
(It'll be easier to find these numbers with practice)
Now in the function instead of bx, split it and use (number 1)x + (number 2)x
It's allowed because it's the same value since N1 + N2 = bx already
x^2 + 15x + 56
Now is:
x^2 + 8x + 7x + 56
Now you can factor this function much easily because it can transformed into:
(x + 8)(x) + (x + 8)(7)
x + 8 is the common factor
it can become:
(x + 8) (x + 7)
The sides of the rectangle are 8 and 7
Hope this helps you with factoring :)

Use the given information to write an equation and solve the problem.
(28-31 in the picture)
Answer:
28. 120 degrees
29. 30 degrees
30. 56 degrees & 124 degrees
31. 72 degrees, 108 degrees, and 18 degrees
Step-by-step explanation:
We assign variable x for the answer we are looking for (28-29).
28.
Supplement means x + y = 180 degrees. We also know x = 2y. Substitution gives us 3y = 180 degrees, so y = 60 degrees and x = 120 degrees.
29.
Complement means x + y = 90 degrees. We are given 2x = y. Substitution brings us 3x = 90 degrees, x = 30 degrees.
30.
Supplement means x + y = 180 degrees. We are told that y = 2x + 12, so we substitute. This gives 3x + 12 = 180 degrees, x = 56 degrees. Substituting that back into the equation for y, we get 124 degrees.
31.
Supplement means x + y = 180 degrees. Complement means x + z = 90 degrees. Using our given info, we know y = 6z. We can substitute that in to get x + 6z = 180. Subtracting our second and third equations, we get 5z = 90, z = 18 degrees. Therefore, x = 72 degrees, y = 108 degrees.

The required first five-term of the geometric progression is 16, 28, 49, 85.75, 150.06.
Given that,
A geometric sequence h starts at 16 and has a growth factor of 1.75 what are the first 5 terms is to be determined.
Geometric progression is sequence of series whose ratio with adjacent values remains same.
Here,
For the geometric progression,
a = 16
r = 1.75
The required sequence is given as,
1st = a = 16
2nd = ar = 16 (1.75) = 28
3rd = ar² = 16(1.75)² = 49
Similarly,
4th = 85.75
5th = 150.06
Thus, The required first five-term of the geometric progression is 16, 28, 49, 85.75, 150.06.

Evaluate 6 to the power of negative 2
A. -1/36
B. -12
C. -36
D. 1/36
Answer:
Positive 1 over 6 raised to the 2nd power 1/62 or 1 over 36 which is 1/36. To find -6-2, take the inverse of -62.
(first find -62) -62 = -6 * -6 = 36
(then take the inverse of 36, which is 1 over 36) = 1 / 36 = 0.0277
so, -6-2 =0.0277

Question
Find the equation of the line with slope m
=
2 that contains the point (8,19).
Answer: y= 2x + 3
Step-by-step explanation:
Point slope formula: y = mx + b
Since the given point is (8,19), 19 is our y, and 8 is our x. Since the slope is 2, our m is 2.
Sub in values.
y = mx + b
19 = 2(8) +b
19 = 16 + b
b = 19-16
b = 3
Now that we have m and b, we can make the equation.
y = mx + b, sub in 2 for m and 2 for b
y = 2x + 3
19 = 2(8) + 3
19 = 16 + 3
19 = 19
So the answer is y = 2x+3
Find the length s of the circular arc. (Assume r = 2 and = 116°.)
Answer:
length of an arc = θ/360 × 2πr
θ=116°
r=2
π= 3.14
l= 116/360 ×2×3.14×2
l= 4.047= 4.05cm
Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate
Step-by-step explanation:
Area of a Triangle:
bh/2
8 ft is the given height
6 ft is the given base (or width)
(8)(6)/2
48/2
= 24 ft²
In addition to this, we will have to find the area of the semicircle.
Area of a Semicircle:
πr²/2
The question tells us to use 3.14 in place of π.
3.14r²/2
The diameter is 8 ft as it is given to us in the diagram, but in the formula we would have use the radius, and because the radius ia half of the diameter we will divide 8 by 2.
8/2
= 4
3.14(4)²/2
Solve...
3.14(16)/2
50.24/2
= 25.12 ft²
Now that we have found the area of both the triangle and the semicircle, we can add them together to find the area of the figure.
24 ft² + 25.12 ft²
= 49.12 ft²
Our final answer is A=49.12 ft² because it is already in the hundredths place.
