What is the length of the other diagonal DF?
5 cm
16 cm
21 cm
32 cm
Applying the Pythagorean theorem, the length of diagonal DF is: C. 21 cm.
What is the Pythagorean Theorem?The sum of the squares of the two shorter legs of a right triangle equals the square of the length of the longest leg.
Let the point of intersection of the diagonals be O.
Diagonal FD bisects diagonal EG into equal segments EO and OG. EO = OG = 24/2 = 12 cm
Find the lengths of FO and OD using the Pythagorean theorem:
FO = √(20² - 12²) = 16 cm
OD = √(13² - 12²) = 5 cm
Length of diagonal DF = FO + OD = 16 + 5 = 21 cm.

When segments intersect inside a circle, what is the relationship between the angle of intersection and the intercepted arcs?
Answer:
Angle of intersection is one half of the sum of measurements of intercepted arcs.
Step-by-step explanation:
An inscribed angle is the angle formed by the intersection of two chords having a common endpoint in a circle.
Also, by the angles of Intersecting Chords Theorem,
When two chords intersect inside a circle, then the measure of the angle formed is one half of sum of the measure of the arcs intercepted by the angle and its vertical angle.
Which is the relationship between the angle of intersection and the intercepted arcs.

find the nonpermissible replacement for the variable x in this expression (x^2)/(2x-4) ? find the nonpermissible replacement for the variable x in this expression (x^2)/(2x-4) ?
The non-permissible replacements for the variable x in the expression (x^2)/(2x-4) are x = 0 and x = 2.
Explanation:An expression is undefined when its denominator is equal to zero. Therefore, we need to find the values of x that make the denominator, 2x-4, equal to zero.
Solve the equation for x: 2x - 4 = 0 2x = 4 x = 2
Therefore, x = 2 is a non-permissible replacement because it makes the denominator zero.
Additionally, the expression also includes x^2 in the numerator. Since any number multiplied by zero is still zero, dividing any non-zero number by zero results in undefined. Therefore, x = 0 is also a non-permissible replacement.
In conclusion, the non-permissible replacements for the variable x in the expression (x^2)/(2x-4) are x = 0 and x = 2.
Write the rule for the nth term of an arithmetic sequence in which a10=46 and d=3
Final answer:
The rule for the nth term of the arithmetic sequence is given by the formula a_n = 19 + (n - 1)×3, where a1 is the first term of the sequence and d is the common difference.
Explanation:
To write the rule for the nth term of an arithmetic sequence where the 10th term a10 is 46 and the common difference d is 3, we use the formula:
an = a1 + (n - 1)d
We have that:
a10 is the 10th term of the sequence which is 46.
The common difference d is 3.
Firstly, we need to find a1, the first term of the sequence. We can use the given a10 to find a1.
a10 = a1 + (10 - 1)×3
46 = a1 + 9×3
46 = a1 + 27
a1 = 46 - 27
a1 = 19
Now we can write the rule for the nth term:
an = 19 + (n - 1)×3
This formula allows us to calculate any term in the sequence by substituting the desired term number for n.

Knowing that you use 275 KWH from 7am-7pm and 265 KWH 7pm-7am, answer the question.
How much have you paid on the NightTImer plan?
NightTimer Plan: If more than 50% of usage is outside of 7pm-7am, then you have to pay the DayTimer rate for all power used between 7am-7pm. $0.06445/KWH
DayTimer: As long as most power used if from 7am-7pm, then you receive a 20% discount on power usage between 7pm-7am.
$0.06831/KWH
Answer: 35.86
Step-by-step explanation:
By applying the DayTimer and NightTimer plans' rules and doing the necessary calculations, the total payment on the NightTimer plan would be $33.26747.
Explanation:The total power used from 7am-7pm is 275 KWH and from 7pm-7am is 265 KWH. In this case, you have used more power during the 7am-7pm period. As such, you qualify for the DayTimer plan's rate. Therefore, you pay $0.06831/KWH for the power used between 7am-7pm, which results in 275 KWH * $0.06831/KWH = $18.78575. However, since most of your power usage is from 7am-7pm, you receive a 20% discount on your night usage. The night rate, therefore, is 20% less than the DayTimer rate, which is $0.06831 * (1 - 20/100) = $0.054648/KWH. Hence, you will pay 265 KWH * $0.054648/KWH = $14.48172 for power used between 7pm-7am. By adding these two amounts together, your total payment on the NightTimer plan would be $18.78575 + $14.48172 = $33.26747.

What is the simplified form of x + 6/3 - x + 2/3
The simplified form of the given expression x + 6/3 - x + 2/3 is 8/3 after combining like terms and simplifying the constants.
The question involves simplifying a mathematical expression.
The expression given is:
x + 6/3 - x + 2/3.
To simplify this expression, combine like terms.
Since x is present in both the first and third terms, they cancel each other out.
Next, combine the constant terms 6/3 and 2/3. This results in:
6/3 + 2/3 = (6 + 2) / 3 = 8/3
The simplified form of the expression is therefore 8/3.

An employee receives a weekly salary of $340 and a 6% commission on all sales.
Find the employee's earnings for a week with $660 total sales.
The employee earns a fixed salary of $340 plus a 6% commission on sales. In a week with $660 in sales, his total earnings would be $379.60.
Explanation:The employee's weekly income is a combination of a fixed salary and a percentage of sales. His fixed salary is $340. From his sales, he earns a 6% commission. So for a week with $660 in sales, the commission would be 6/100 * 660, which equals $39.60. Adding this commission to the fixed salary: $340 + $39.6 = $379.60. So, the employee's overall earnings for the week would be $379.60.

What is 75% of 90? 67.5 6750 675 6.75
To calculate 75% of 90, convert the percentage to a decimal (0.75) and multiply it with 90, resulting in 67.5.
To find 75% of 90, we can use the concept that 'percent' means 'per hundred'. The calculation involves turning the percentage into a decimal by dividing by 100 and then multiplying by the number in question. Thus, 75% can be written as 0.75 (since 75 divided by 100 equals 0.75).
Therefore, to find 75% of 90, we multiply 90 by 0.75:
0.75 × 90 = 67.5
The correct answer is 67.5, not 6750, 675, or 6.75.
