b) x= 64/15, y= 17/15
c) x= 8/15, y= 136/15
d) x= 64/15, y= 136/15
Answers
1) Triangle ABC
2) Triangle CDB
Using pythagorean theorem, we can write equations for both triangles.
For triangle ABC:
[tex] (15+x)^{2}= 17^{2}+ y^{2} [/tex]
For triangle CDB:
[tex] y^{2}= 8^{2}+ x^{2} [/tex]
Using the value of y² in the first equation, we get:
[tex] (15+x)^{2}= 289 + 64 + x^{2} \\ \\ 225+30x+ x^{2} =353 + x^{2} \\ \\ 30x=128 \\ \\ x= \frac{128}{30} \\ \\ x= \frac{64}{15} [/tex]
[tex]y^{2}= 8^{2}+ x^{2} \\ \\ y^{2}=64+ ( \frac{64}{15} )^{2} \\ \\ y^{2}= \frac{18496}{25} \\ \\ y= \frac{136}{15} [/tex]
Thus the d option gives the correct values of x and y

Answer:

Step-by-step explanation:
It is given that figure shows circle C with diameter LM and inscribed ∠LMN and m∠LMN=32° .
We know that the angle formed at the center is double the angle formed on the vertex that is an inscribed angle, thus on joining NC, we have
[tex]{\angle}NCL=2({\angle}LMN)[/tex]

1. What is the sum of the finite arithmetic series? 26 + 29 + 32 + 35 + 38 + 41 + 44
2. What is the sum of the finite arithmetic series? 7.6 + 6.3 + 5 + 3.7 + 2.4 + 1.1 + (–0.2) + (–1.5),
Answers
The sum of the finite arithmetic series 26 + 29 + ... + 44 is 245. The sum of the series 7.6 + 6.3 + ... + (-1.5) is 24.4.
To solve these problems, we will use the formula for the sum of a finite arithmetic series, which is given by S = n÷2 × (a₁ + aₙ), where S represents the sum of the series, n is the number of terms, a₁ is the first term, and aₙ is the last term.
Problem 1:
The series is: 26, 29, 32, 35, 38, 41, 44. First, we find the number of terms (n). Since the common difference (d) is 3, we have n = (44 - 26)÷3 + 1 = 7. Now, apply the formula to find the sum: S = 7÷2 × (26 + 44) = 245.
Problem 2:
The series is: 7.6, 6.3, 5, 3.7, 2.4, 1.1, -0.2, -1.5. Here, d = -1.3 and n = 8. So the sum is: S = 8÷2 × (7.6 - 1.5) = 24.4.

2. Is 4x - 3 = 19 is open, because this could be a valid equation.
3. 16 = 4x - 4
So, 16+4=4x; 4x=20; x=20/4; x=5..... option C is the correct one.
4. length of the classroom is 2.4 times its width.
given length = 42 in, and since length = 2.4 times width, width = 42/2.4,
hence option A) 17.5 in is correct
5. x - 3 = 10
x = 10+3 =13
Option B is the right one.
The answer of the following mathematical expressions are,
1. True
2. False

5. B. x = 13
Let's go through each of the expression ,
Is -7 + 9 = -9 + 7 true, false, or open?
It is option A. True
Both sides of the equation simplify to 2, so the equation is true.
Is 4x - 3 = 19 true, false, or open?
It is option B. False
When you solve for x, you get 4x = 22, and then x = 5.5. Therefore, the equation is false.
Which of the following is a solution to the equation 16 = 4x - 4?
The value of x is option C. 5
When you solve for x, you get 4x = 20, and then x = 5. So, x = 5 is a solution to the equation.
An art student wants to make a model of the classroom. The length of the classroom is 2.4 times its width. The length of the student's model is 42 inches. What should the width of the model be?
The width is equal to option A. 17.5 inches
If the length is 2.4 times the width, then the width should be 42 inches / 2.4 = 17.5 inches.
Use mental math to determine the solution to x - 3 = 10.
the value of x is option B. x = 13
Adding 3 to both sides of the equation gives x = 10 + 3, which is x = 13.

Worker A earns $8.10 per widget produced, produces 10 widgets per day, and works 9 hours per day. Worker B earns $8.40 per widget produced, produces 8 widgets per day, and works 7 hours per day. Which of these statements is true?
A. Worker B earns more per day than worker A but less per hour than worker A.
B. Worker A earns more per day than worker B but less per hour than worker B.
C. Worker A earns more per day than worker B and more per hour than worker B.
D. Worker B earns more per day than worker A and more per hour than worker A.
Answers
Total earning per day = $8.10 x 10 = $81
He works 9 hours a day. Find the rate for 1 hour.
81 ÷ 9 = 9
He earns $9 an hour
Worker B:
Total earning per day = $8.40 x 8 = $67.20
He worked 7 hours a day. Find the rate for 1 hour.
67.20 ÷ 7 = $9.60
He earns $9.60 per hour
Worker A earns more per day than worker B but less per hour than worker B. (Answer B)
By calculating the total earnings per day and earnings per hour for Worker A and Worker B, we deduce that Worker A earns more per day than Worker B but earns less per hour than Worker B.
Explanation:To answer this question, we first need to calculate the total earnings per day and then the earnings per hour for both Worker A and Worker B.
For Worker A, the total earnings per day can be calculated as: 10 widgets/day * $8.10/widget = $81/day. For Worker B, the total earnings per day can be calculated as: 8 widgets/day * $8.40/widget = $67.20/day.
Therefore, we can see that Worker A earns more per day than Worker B.
Next, we calculate the earnings per hour. For Worker A, the earnings per hour amount to: $81/day ÷ 9 hours/day = $9/hour. For Worker B, the earnings per hour amount to: $67.20/day ÷ 7 hours/day = $9.60/hour.
Thus, Worker B earns more per hour than Worker A.
Given the calculations, the correct statement is B. Worker A earns more per day than Worker B but less per hour than Worker B.

B: p= 11, q= 4
C: p= -2, q= -5
D: p= 1, q= 10
Answers
c = p * q
So that c <0
We have that the possible values are:
p = -3
q = 7
Thus, the value of c is:
c = p * q
c = (- 3) * (7)
c = -21 <0
Answer:
the possible values of p and q could be
A: p = -3, q = 7
Explanation:
Let's solve it smartly!
Given expression: [tex] x^{2} + bx +c[/tex] --- (A)
Factors: (x+p)(x+q)
Condition: c<0
Now let us expand (x+p)(x+q):
=> [tex] x^{2} + (p+q)x + pq[/tex] --- (B)
By comparing (B) with (A), we can say that:
pq = c --- (C)
Now, as the condition says, c<0, it means either p or q is negative. Both cannot be positive or both cannot be negative.
1) If p>0, q>0, it means c>0 since (+p)(+q) = (+c)(according to equation (C)). Condition is not met.
Hence, option B and D are wrong.
2) If p<0, q<0 it means c>=0 since (-p)(-q) = (+c)(according to equation (C)). Condition is not met.
Hence option C is out as well.
We are left with Option A:
p<0, q>0 it means c<0 since (-p)(+q) = (-c)(according to equation (C)). Condition is MET!
Hence,
Ans: Option A: p= -3, q= 7

Answers
The sixth term of an arithmetic sequence, with a fifth term of 11 and a common difference of 4, is calculated to be 15.
Explanation:The student's question is about determining the sixth term of an arithmetic sequence when the fifth term and the common difference are given. The fifth term is 11, and the common difference is 4. To find the sixth term, we follow the definition of an arithmetic sequence where each term is equal to the previous term plus the common difference.
Arithmetic sequence formula
:
Tn = T(n-1) + d
Where:
Tn is the nth termT(n-1) is the previous termd is the common differenceApplying this formula to find the sixth term:
Sixth term = Fifth term + Common difference
= 11 + 4
= 15
Therefore, the sixth term of the sequence is 15.

Answers
An asymptote is a line that approaches a curve indefinitely without intersecting it at any finite point. Examples include the line y = 0 for the function y = 1/x, whereas a non-example would be the intersecting line y = x with a parabola y = x^2.
Explanation:An asymptote is a line that a curve approaches as it heads towards infinity, but never actually reaches.
There are several characteristics of an asymptote that are notable. First, the distance between the curve and the asymptote approaches zero as one moves along the curve towards infinity. However, the curve will never intersect the asymptote at any finite point. There are two main types of asymptotes: vertical and horizontal.
An example of an asymptote is the line y = 0, which is a horizontal asymptote for the function y = 1/x as x approaches infinity.
A common non-example of an asymptote is any line or curve that intersects a graph at a finite number of points, such as the line y = x when compared with a parabola y = x2.
