Answer:
(w - 4)(w - 1)(3w - 5)
Step-by-step explanation:
Using Synthetic division to find the quotient on dividing p(w) by (w - 4)
4 | 3 - 20 37 - 20
12 - 32 20
-----------------------------
3 - 8 5 0 ← remainder = 0
quotient = 3w² - 8w + 5 = (3w - 5)(w - 1)
p(w) = (w - 4)(w - 1)(3w - 5)

What is the value of 4y when y=-3
Answer:
-12
Step-by-step explanation:
a positive times a negative is a negative
Uisng the appropriate arithmetic operation, the value of 4y when y = - 3 is - 12.
To obtain the value of 4y, we substitute, the value of y into the equation thus :
4y ; y = - 34(-3) = 4 × - 3
4(-3) = - 12
Hence, the value of 4y = - 12

The perimeter of a square is 80 cm. What is the area?
Answer:
A = 400 cm^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
80 = 4s
Divide each side by 4
80/4 = 4s/4
20 =s
We want to find the area of the square
A = s^2
A = 20^2
A = 400 cm^2
during the last few months, maria has seen deer in her backyard on 13 days and no deer on 52 days. What is the approximate probability that she will see deer in her yard tomorrow?
A) 0.25
B)1/5
C) 33.3 %
D) 2/3
Answer:
B) 1/5
Step-by-step explanation:
First you would have to find the total number of days.
52 + 13 = 65
The total number of days is 65.
Reread the question. The question is, "What is the approximate probability that she will see deer in her yard tomorrow?"
She has seen deer in her yard for 13 days, so the equation to figure this out would be:
13 divided by 65 = 0.2 or 1/5
I also took the Quiz and got it correct :)
(If you found this helpful and got it correct please thank, give 5 stars, and comment your feedback if you can so others know it's correct as well.)
The probability of seeing a deer in her yard tomorrow is 1/5, the correct option is B.
What is Probability?Probability is the likeliness of an event to happen, it has a range from 0 to 1.
Total number of days Maria saw deer is 13 days
Total number of days Maria didn't saw the deer is 52 days
The total number of days is 65
Probability of seeing a deer = Number of days deer was seen / Total
number of days
Probability = 13/65
Probability = 1/5

You have a cylindrical pond that has a diameter of 30 feet and has a depth of 5 feet. If you need to fill the pond one-quarter of the way up with water and water costs $3.25 per cubic foot, how much will you need to spend to fill the pond?
First, calculate the volume of water needed to fill the pond one-quarter of the way up, then multiply that by the cost per cubic foot to find the total cost, which is approximately $2297.29.
Explanation:The subject of this question is Mathematics, more specifically, it involves the use of geometry and algebra. The question is asking about the cost of filling a cylindrical pond one-quarter of the way up with water, given the dimensions of the pond and the price of water per cubic foot.
To answer this question, we first need to determine the volume of water needed. Since the pond is cylindrical, we use the formula for the volume of a cylinder: V = πr²h, where r is the radius and h is the height. The diameter is given as 30 feet, so the radius is 15 feet (half the diameter), and we're filling to a depth of 1.25 feet (one-quarter of the 5-foot depth). This gives us a volume of approximately 706.86 cubic feet.
We then multiply this volume by the price of water. At $3.25 per cubic foot, that's a total cost of about $2297.29. So, you would need to spend approximately $2297.29 to fill the pond one-quarter of the way up with water.

Select all of the following that are quadratic functions.
x = 3y2 – 6y + 5
y + 3 = –2 x 2+ 5
y = 2 x 2 – 8 x + 6
y= –7 x – 4
y – 3 x = 4 x 3 – x2 + 9
y = 5 x(x + 9) – 8
y – 2 x 2 = 3 x – 2 x 2 + 4
2. y + 3 = -2x^2 + 5
3. y = 2x^2 - 8x + 6
6. y = 5x (x+9) - 8
Out of the given functions, y + 3 = –2 x 2+ 5, y = 2 x 2 – 8 x + 6, y = 5 x(x + 9) – 8 and y – 2 x 2 = 3 x – 2 x 2 + 4 are quadratic functions. They fit the standard quadratic form a*x^2 + b*x + c = y.
Explanation:A function can be classified as a quadratic function if it can be written in the standard form a*x^2 + b*x + c = y, where a, b, and c are constants and a is not equal to zero. Quadratic functions graph as a parabola.
x = 3y2 – 6y + 5: This is not a quadratic function in y due to its form.y + 3 = –2 x 2+ 5: This is a quadratic function in variable 'x' once rearranged to the standard form.y = 2 x 2 – 8 x + 6: Thus is a quadratic function. It clearly fits the standard form.y= –7 x – 4: This is a linear function in 'x', not quadratic.y – 3 x = 4 x 3 – x2 + 9: This is a cubic function due to the term with x^3, not quadratic.y = 5 x(x + 9) – 8: After expanding the multiplication to get y = 5x^2 + 45x - 8, we can see that it is a quadratic function.y – 2 x 2 = 3 x – 2 x 2 + 4: This is a quadratic function in 'x' once rearranged to the standard form.Learn more about Quadratic Functions here:https://brainly.com/question/35505962

Valerie said that the GCF of two monomials is 7bc.
What two monomials did she use?
Answer: B: 35ab^2c AND 7bc^2
Step-by-step explanation:
The monomials must be multiples of 7bc such as 21b^2c and 14bc^2, because the GCF of two monomials is the highest factor that divides both these monomials. GCF in this case is 7bc.
Explanation:The Greatest Common Factor (GCF) of two monomials is the highest factor that divides both of these monomials. Given that the GCF is 7bc, these two monomials must have 7bc as a factor. Thus, Valerie possibly used any two monomials that are multiples of 7bc.
For example, one answer could be 21b^2c and 14bc^2. Each of these monomials has 7bc as a factor (3b, 2c, and 2b, 2c respectively). There are other possible combinations, as long as they're multiples of 7bc.

Which is the simplified form of r Superscript negative 7 Baseline + s Superscript negative 12?
StartFraction 1 Over r Superscript 7 Baseline s Superscript 12 EndFraction
Negative r Superscript 7 Baseline minus s Superscript 12
StartFraction r Superscript 7 Over s Superscript 12 EndFraction
StartFraction 1 Over r Superscript 7 Baseline EndFraction + StartFraction 1 Over s Superscript 12 EndFraction
Final answer:
The correct simplified form is \(\frac{1}{r^7} + \frac{1}{s^{12}}\), with each term representing the reciprocal of the base raised to a positive exponent and kept as separate terms.
Explanation:
The simplified form of r-7 + s-12 is \(\frac{1}{r^7} + \frac{1}{s^{12}}\). The negative exponents indicate that each term is the reciprocal of the base raised to the positive exponent. So, r-7 becomes \(\frac{1}{r^7}\) and s-12 becomes \(\frac{1}{s^{12}}\). Since these are two separate terms, they are not combined together into a single fraction.
Jay won 14 out of the last 20 video games he played. Find the probability of Jay winning the next video game he plays.
Answer:
0.7 or 70 percent
Step-by-step explanation:
Jay's probability of winning the next game, based on his past record, would be 70%. However, probability doesn't guarantee future outcomes as the future performance depends on various factors.
Explanation:The question requires us to find out the probability of Jay winning the next video game he plays, given his past record. Jay has won 14 out of the last 20 games, which gives us a winning probability of 14/20 = 0.7 or 70%. Probability assumes the conditions remain the same, it doesn't guarantee that the next outcome will be a win.
However, notice that past performance doesn't necessarily indicate future results, especially in random situations such as a game. The future outcome depends on the conditions of the next game he plays and his performance in it. The past winning record of 70% can be taken as an indication of Jay's skills or chances under similar conditions, but not a certainty for future games.

find the exact value of tan(x+y) if csco= 5/3 and cosy=5/13
Answer:
-63/16
Step-by-step explanation:
csc x = 5/3
sin x = 3/5
So x is the angle in a 3-4-5 triangle, opposite of the 3.
cos y = 5/13
So y is the angle in a 5-12-13 triangle, opposite of the 12.
tan(x + y) = (tan x + tan y) / (1 − tan x tan y)
tan(x + y) = (3/4 + 12/5) / (1 − (3/4)(12/5))
tan(x + y) = (3/4 + 12/5) / (1 − 9/5)
tan(x + y) = (15 + 48) / (20 − 36)
tan(x + y) = -63/16

Can someone help me with a and b thank you
Given:
a) Area = 121 ft²
b) Area = 81 yd²
To find:
The side length of each square
Solution:
a) Area = 121 ft²
Area of the square = s²
⇒ s² = 121
Taking square root on both sides.
[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 121}[/tex]
[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 11^2}[/tex]
Square root and squares get canceled.
⇒ s = 11
The length of each side of the square is 11 ft.
b) Area = 81 yd²
Area of the square = s²
⇒ s² = 81
Taking square root on both sides.
[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 81}[/tex]
[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 9^2}[/tex]
Square root and squares get canceled.
⇒ s = 9
The length of each side of the square is 9 yd.
