Answer:
D. 21 ft
Step-by-step explanation:
We need to use Power of Points, which basically says that for intersecting chords in a circle (see attachment), a * b = c * d.
Here, we can say that a = x, b = 6, c = 7, and d = 18. Then, we have the equation:
ab = cd
x * 6 = 7 * 18
6x = 126
x = 21
Thus, x is 21 ft.
Hope this helps!
Answer:
Last one: 21 ft
Step-by-step explanation:
x × 6 = 7 × 18
x = (7 × 18)/6

W (t) models the daily water level (in cm) at a pond in Arizona, t days after the hottest day of the year. Here, t is entered in radians:
w(t) = 15 cos ((2pi / 365)t) + 43
What is the first time after the hottest day of the year that the water levels is 30 cm?
Answer:
152 days
Step-by-step explanation:
Given:
w(t) = 15 cos ((2π / 365)t) + 43
To find first time after the hottest day of the year that the water levels is 30 cm, substitute with w(t) = 30 and solve for t
30 = 15 cos ((2π / 365)t) + 43
30 - 43 = 15 cos ((2π / 365)t)
15 cos ((2π / 365)t) = -13
cos ((2π / 365)t) = -13/15
(2π / 365)t = cos⁻¹ (-13/15) = 150.07° ≈ (5/6) π
t = (365/2) * (5/6) ≈ 152 days
So, the first time after the hottest day of the year that the water levels is 30 cm is after 152 days
The water level reaches 30 cm approximately 125.3 days after the hottest day of the year. This was calculated by setting the given equation equal to 30 cm, isolating the variable, and using inverse cosine to solve in terms of radians.
Explanation:The given equation represents a cosine function, w(t) = 15cos(2π / 365)t + 43, which models the water level in a pond. Here, 15 is the amplitude, and 43 is the vertical shift, indicating the average water level is 43 cm. To find the first time after the hottest day of the year that the water level is 30 cm we first set w(t) equal to 30 and solve this for t:
30 = 15cos((2π / 365)t) + 43,
Subtract 43 from both sides to get:
-13 = 15cos((2π / 365)t),
Next, divide both sides by 15 to get:
-13/15 = cos((2π / 365)t),
Now, use the inverse cosine function, or arccos, to solve for the argument (2π / 365)t, which is in radians:
(2π / 365)t = arccos(-13/15).
Thus, t = (365 / 2π) * arccos(-13/15). This equation can be solved using a calculator that provides results in radians. The solution is approximately 125.3 days after the hottest day of the year.

Quadrilateral BEAR is inscribed in circle o,
What is the measure of R?
If Quadrilateral BEAR is inscribed in circle o,then the measure of R is 106 degrees.
What is Quadrilateral?A quadrilateral is a four-sided polygon, having four edges and four corners.
The sum of angles of a quadrilateral is 360 degrees.
Angle E is 74 degrees.
Angle A is 92 degrees.
We need to find the angle R.
The angle at B is 90 degrees as it makes right angled.
∠E+∠A+∠R+∠B=360
74+92+∠R+90=360
256+∠R=360
Subtract 256 on both the sides
∠R=360-256
∠R=106 degrees.
Hence, the measure of R is 106 degrees.

A certain company gives its salespeople a bonus every six months. This bonus is calculated by averaging (taking the mean of) the four middle monthly sales values (that is, ignoring the highest and lowest) from the six-month window, taking 12% of the result, and splitting it evenly among the salespeople. The graph below shows sales for the most recent bonus period. A bar graph titled Total Sales has month on the x-axis and sales (dollars times 1,000) on the y-axis. January, 21.6; February, 18.9; March, 29.2; April, 18.4; May, 17.1; June, 26.1. If there are five salespeople, how much money will each one receive, to the nearest dollar? a. $556 b. $525 c. $510 d. $486
Answer:
The answer is C. $510.
I have just took the test.
Option C is correct, Each person receives an amount of $510.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To calculate the bonus, we need to find the four middle monthly sales values.
Arranging the sales values in ascending order, we get:
17.1, 18.4, 18.9, 21.6, 26.1, 29.2
The four middle values are: 18.4, 18.9, 21.6, and 26.1.
Average= (18.4 + 18.9 + 21.6 + 26.1) / 4 = 21.25
Taking 12% of this value gives:
0.12 x 21.25 = 2.55
The bonus amount to be split among the five salespeople is $2.55. Therefore, each salesperson will receive:
2.55 / 5 = 0.51
Therefore, each salesperson will receive $1 as a bonus.
Hence, Option C is correct, Each person receives an amount of $510.

find the sum of 997 + 992 + 987 +...+ 257 +252
Answer:
93,675
Step-by-step explanation:
We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.
The number of terms in the sequence (n) can be found from the formula for the n-th term:
an = a1 +d(n -1)
(an -an)/d +1 = n
(252 -997)/(-5) +1 = n = 150
The sum of these terms is the average of the first and last terms, multiplied by the number of terms:
S150 = (997 +252)/2·150 = 93,675
The sequence sum is 93,675.

The graph shows the function f(x) = |x-hl + k. What is the
value of K?
k=-2.5
k=-1
k=1
k= 2.5
Answer:
Step-by-step explanation:
While the h portion of that absolute value represents the side to side movement, the k represents the up and down. The pointy part of the graph (the vertex) is lowered from its position at y = 0 to y = -2.5
So k = -2.5
The correct value of k is k = -2.5. Hence, option a is correct.
To find the value of k for the function f(x) = |x - h| + k, you can use one of the given points, as all points lie on the graph of the function.
Let's use the point (1, -2.5) with coordinates (x, y).
Plug these coordinates into the function:
-2.5 = |1 - h| + k
Now, you need to find k:
-2.5 = |1 - h| + k
To isolate k, you can solve for k:
k = -2.5 - |1 - h|
Now, let's check which option fits this equation based on the given points:
For h = 1 (as in the point (1, -2.5)), you get:
k = -2.5 - |1 - 1| = -2.5 - 0 = -2.5
So, the correct value of k is k = -2.5.
