If (x-y)^2=100 and xy=20. what's the value of x^2+y^2?
Answer: The value of [tex]x^2+y^2[/tex] is 140
Step-by-step explanation:
We are given an expression:
[tex](x-y)^2=100[/tex]
And,
xy = 20
Using the identity:
[tex](a-b)^2=a^2+b^2-2ab[/tex]
Solving the expression:
[tex]x^2+y^2-2xy=100[/tex]
Putting the value of 'xy' in above equation, we get:
[tex]x^2+y^2-2(20)=100\\\\x^2+y^2=100+40\\\\x^2+y^2=140[/tex]
Hence, the value of [tex]x^2+y^2[/tex] is 140
In the △PQR, PQ = 39 in, PR = 17 in, and the altitude PN = 15 in. Find QR.
Final answer:
To find the length of QR, we used the Pythagorean theorem on triangle PNQ to find NQ, then added it to PR, resulting in QR measuring 53 inches.
Explanation:
To find the length of side QR in △PQR, we can apply the Pythagorean theorem to one of the right triangles formed by the altitude PN. The triangle we'll use is △PNQ, where NQ is part of QR, and PN is given as 15 in.
Firstly, we can calculate NQ using the Pythagorean theorem:
PN² + NQ² = PQ²
15² + NQ² = 39²
NQ² = 39² - 15²
NQ² = 1521 - 225
NQ² = 1296
NQ = √1296
NQ = 36 in
Since PR = 17 in, we can conclude that NR is the difference between PR and NQ:
NR = PR - NQ
NR = 17 - 36
NR = -19 in
The negative value indicates a mistake since lengths cannot be negative. Therefore, we should use the entire length of PQ instead:
QR = NQ + NR
QR = 36 + 17
QR = 53 in
Thus, side QR measures 53 inches.
Which of the following equations is perpendicular to y = 2x + 5 and passes through the point (4 , 6)? A. y = – 1 2x + 8 B. y = 2x + 8 C. y = – 1 2x – 2 D. y = 2x – 2
Answer:
The equation would be y = -1/2x + 8
Step-by-step explanation:
To find the equation of the line, we start by find the slope. Perpendicular slopes have opposite and reciprocal slopes. since the original slope is 2, then the perpendicular slope is -1/2.
Now, using the point and the slope in point-slope form, we can find the equation.
y - y1 = m(x - x1)
y - 6 = -1/2(x - 4)
y - 6 = -1/2x + 2
y = -1/2x + 8
The equations that is perpendicular to y = 2x + 5 and passes through the point (4 , 6) is y = - 1/2 x + 8
For an equation to be perpendicular to the another line equation the product of there slope will be negative one. Therefore,
m₁m₂ = -1Therefore, the slope of y = 2x + 5 is 2. The equation should have the following slope:
2m₂ = - 1
m₂ = -1 / 2
A linear equation is represented as follows:
y = mx + bm = slope
b = y-intercept
Therefore,
let use the point (4 , 6) to find b
6 = - 1/2 (4) + b
6 = -2 + b
b = 6 + 2
b = 8
The equation will be as follows:
y = - 1/2 x + 8

Nikita knows the following information about her food club that has 1111 members: 33 members like neither fruit nor vegetables. 44 members like fruit but not vegetables. 55 members in total like fruit. Can you help Nikita organize the results into a two-way frequency table?
Answer:
[tex]\begin{array}{cccc}&\text{ Like fruit }&\text{ Do not like fruit }&\text{ Total }\\\text{Like vegetables}&11&1023&1034\\\text{Do not like vegetables}&44&33&77\\\text{Total}&55&1056&1111\end{array}[/tex]
Step-by-step explanation:
You are given such information:
food club has 1111 members;33 members like neither fruit nor vegetables;44 members like fruit but not vegetables;55 members in total like fruit.Then 55 - 44 = 11 members like fruit and vegetables. Thus,
1111 - 55 - 33 = 1023 members like vegetables but not like fruit.
A two-way frequency table will take look
[tex]\begin{array}{cccc}&\text{ Like fruit }&\text{ Do not like fruit }&\text{ Total }\\\text{Like vegetables}&11&1023&1034\\\text{Do not like vegetables}&44&33&77\\\text{Total}&55&1056&1111\end{array}[/tex]
Nikita can organize her data into a two-way frequency table showing members' preferences for fruit and vegetables. The table identifies how many members like only fruit, only vegetables, both, or neither accordingly.
Nikita has the following data about her food club consisting of 1111 members:
33 members like neither fruit nor vegetables.44 members like fruit but not vegetables.55 members in total like fruit.We can organize this information into a two-way frequency table. Here are the steps:
Calculate the number of members who like both fruit and vegetables. Since 55 members like fruit, 44 like only fruit, and 33 like neither, we subtract the 44 members who like only fruit from the total 55 fruit-likers to find those who like both: 55 - 44 = 11.
Calculate the number of members who like vegetables only. The number of members who like either fruit or vegetables or both can be found by subtracting those who like neither from the total number of members: 1111 - 33 = 1078. We already know 55 like fruit, so those who like vegetables only: 1078 - 55 = 1023 (1111 total members - 33 neither - 55 fruit).
The two-way frequency table looks like this:
Fruit No Fruit Total
Vegetables 11 1023 1034
No Vegetables 44 33 77
Total 55 1056 1111

A basketball player attempts 15 baskets in a game, He makes 9 of the attempted basket. which ratio describe the number of basket the player made to the number of basket the player attempted?
Answer:
3:5
Step-by-step explanation:
We are looking for the ratio of baskets made to baskets attempted
made: attempted
9:15
We can divide each number by 3
9/3: 15/3
3:5
The ratio of baskets made: attempted is 3:5
The ratio that describes the number of baskets made to the number of baskets attempted by the basketball player is 9 to 15, which simplifies to 3 to 5.
The question pertains to the ratio of successful basket attempts to total attempts made by a basketball player in a game.
In this case, the player successfully made 9 baskets out of 15 attempts.
To express this as a ratio, we simply compare the number of made baskets to the total attempts,
thus the ratio is 9 to 15, which can also be simplified by dividing both numbers by their greatest common divisor, which is 3, resulting in a simplified ratio of 3 to 5.

To find the rate of change, find the difference of people at the park at each given hour and divide that by the total number of hours in the given time frame.
Early Time interval:
Hour 1 there was 55 people.
Hour 3 there was 135 people.
The rate of change is 135 - 55 / 3-1 = 80/2 = 40 people per hour.
Late time interval:
Hour 3 had 135 people.
Hour 5 had 175 people.
The rate of change is 175 - 135 / 5-3 = 40/2 = 20 people per hour
20 is less than 40, so the late time interval had the smallest rate change.

In a parallelogram ABCD point K belongs to diagonal BD so that BK:DK=1:4. If the extension of AK meets BC at point E, what is the ratio of BE:EC?
Answer:
BE:EC= 1/3
Step-by-step explanation:
Given ABCD is a parallelogram, Point K is such that it belongs to diagonal BD so that BK:DK=1:4.
If we make an extension of AK which meets BS at point E, then using ΔDKA and ΔEKB, we have
∠DKA=∠EKB (Vertically opposite angles)
∠KDA=∠KBE (Alternate interior angles)
∠DAK=∠BEK (Alternate interior angles)
Thus by AAA similarity,ΔDKA≅ΔEKB
⇒[tex]\frac{AD}{BE}[/tex]= [tex]\frac{DK}{BK}[/tex],
Since, AD= BC,therefore
[tex]\frac{AD}{BE}[/tex]= [tex]\frac{BC}{BE}[/tex]= [tex]\frac{4}{1}[/tex]
Now, BC= BE+EC, ⇒[tex]\frac{BE+EC}{BE}[/tex]= [tex]\frac{4}{1}[/tex]
⇒1+[tex]\frac{EC}{BE} = \frac{4}{1}[/tex]
⇒[tex]\frac{EC}{BE}= 3[/tex]
Reciprocating on both the sides, we get
[tex]\frac{BE}{BC} = \frac{1}{3}[/tex]

Identify the equivalent trigonometric values. A sin 17°, cos 17° B cos 29°, sin 61° C sin 78°, cos 102° D cos 83°, cos 7°
Option B (cos 29° and sin 61°) contains equivalent trigonometric values, as the angles are complementary and adhere to the identity sin(90° - x) = cos(x).
The question asks us to identify equivalent trigonometric values out of the given pairs. The equivalent values will have the same numerical value if their angles are complementary (i.e., they add up to 90°) because of the identity sin(90° - x) = cos(x). Considering this, let's evaluate the provided pairs:
A: sin 17° and cos 17° are not complementary, so they are not equivalent.
B: cos 29° and sin 61° are complementary (29° + 61° = 90°), hence equivalent.
C: sin 78° and cos 102° are not complementary, and 102° is greater than 90°, so they are not equivalent.
D: cos 83° and cos 7° are not complementary, but they are both cosines of different angles, so they are not equivalent.
Thus, the pair with equivalent trigonometric values is B: cos 29° and sin 61°.

3. A family is tracking its spending habits. Over the past year, the grocery bill has ranged from $110 to $170. Suppose you were going to plot these points on a coordinate grid. (a) What is a good scale to use for the y-axis? Explain your reasoning. (b) What is a good interval to use for the y-axis? Explain your reasoning. Answer:
The best way to plot them is by month.
170 - 110 = $60.
We are supposed to plot in months and the above calculation is in year, convert it into months
60/5 = $5 each month
So, the coordinates would be 0, 110 1, 115 2, 120 3, 125
The month will be in the x axis and your money will be the Y axis
A suitable y-axis scale to plot spending habits ranging from $110 to $170 would start at $100 and go up to $180, while a good interval for the y-axis would be $10 to allow for clear plotting of values in whole dollars.
To answer the student's question about how to plot spending habits on a coordinate grid:
A good scale for the y-axis when plotting the family's grocery bills that range from $110 to $170 would be one that fits the entire range of values without being too cramped or too spread out. For instance, a scale that starts at $100 and goes up to $180 would allow all points to be plotted clearly. Since these are monetary values, maintaining a scale that reflects currency would be logical.A good interval for the y-axis could be multiples of $10 since this allows for clear and precise plotting of bills that are likely to be in whole dollars, making the graph easier to read while still being detailed enough to discern differences of $10.

The cost of an office chair is $159 and the markup rate is 24% of the cost. What is A. the dollar markup and B. the selling price?
A. The dollar amout of the markup is found by multiplying the markup rate by the dollar cost. "24% of cost" means "24% × cost". Of course, you know that 24% = 24/100 = 0.24.
... markup = 0.24 × cost = 0.24 × $159 = $38.16
B. The markup is the amount added to the cost to get the selling price. It is the amount by which the cost is marked up.
... selling price = cost + markup = $159.00 +38.16 = $197.16
