Answer:
2√97
Step-by-step explanation:
BD² = BC² + DC²
⇒ BD = √BC² + DC²
= √(18)² + (8)²
= √324 + 64
= √388
Rewrite 388 as 2² · 97.
Factor 4 out of 388.
√4(97)
Rewrite 4 as 2².

Find the nth term of this number sequence 2, 4, 6, 8, ...
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
The given sequence is in Arithmetic progression, and we have to find its nth term ~
So, let's get it solved ~
First term of the sequence is :
a = 2Common difference is :
d = 6 - 4 = 4 - 2 = 2Now, if we have to write the 2nd Term with respect to first one, we can write :
2nd Term = a + (2 - 1)d = a + d = 2 + 2 = 4similarly ~
3rd Term = a + (3 - 1)d = a + 2d = 2 + 4 = 64th Term = a + (4 - 1)d = a + 3d = 2 + 6 = 8Therefore, I similar pattern ~
[tex] \qquad \sf \dashrightarrow \: nth \: term = a + (n - 1)d[/tex]
[tex] \qquad \sf \dashrightarrow \: nth \: term = 2 + (n - 1)2[/tex]
[tex] \qquad \sf \dashrightarrow \: nth \: term = 2(1 + (n - 1))[/tex]
[tex] \qquad \sf \dashrightarrow \: nth \: term = 2(1 + n - 1)[/tex]
[tex] \qquad \sf \dashrightarrow \: nth \: term = 2 n [/tex]
Feel free to ask your doubts, if you have any ~
Answer:
2nStep-by-step explanation:
from the number sequence above, each term except the first is generated by adding 2 to the term immediately preceding it.
the nth term of the sequence is usually designated Tn, and it's usually a function of n
from the number sequence
T1= 2
T2 = 2+2= 4
T3= 4+2= 6
T4= 6+2= 8
therefore, Tn= 2+2×(n-1)
= 2+2n-2
=2-2+2n= 2n
therefore, the nth term of the number sequence= 2nFind the gradient of the line segment between the points (-5,-2) and (4,3).

If today id the 7th day of the month, What is teresa's password?
Using a system of equations, it is found that Teresa's password in the 7th day of the month is of 98.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The rule for her password is defined as follows: A whole number that is equal to four times the fourth power of the day of the month divided by two times the square day of the month. Hence, considering n as the day of the month, the equation is given by:
[tex]P = \frac{4n^4}{2n^2} = 2n^2[/tex]

Based on the information in the two-way table, what is the probability that a person selected at random is Ages 16-18 and has prepared a meal for their family? Round your answer to the nearest tenth of a percent.
The probability that a person selected at random is Ages 16-18 and has prepared a meal for their family
How to determine the experimental probability?From the table of values, we have:
Age 16 - 18 that has performed meal = 8
Total = 30
The probability is then calculated using:
P(16 - 18) = n(16 - 18)/Total
This gives
P(16 - 18) = 8/30
Simplify
P(16 - 18) = 4/15
Hence, the probability is 4/15

Answer:
∠ T = 76°
Step-by-step explanation:
RSTU is a cyclic quadrilateral
the opposite angles of a cyclic quadrilateral sum to 180°

Sonji bought a combination lock that opens with a four-digit number created using the digits 0 through 9. The same digit cannot be used more than once in the combination.
If Sonji wants the last digit to be a 7 and the order of the digits matters, how many ways can the remaining digits be chosen?
84
504
3,024
60,480
Answer:
504 combos
Step-by-step explanation:
Cannot use digits twice and last is '7'
9 digits for first place choice
8 digits for second place
7 digits for third place
only '7' for fourth place 9 x 8 x7 = 504 combos
You can use the rule of product from combinatorics to find out how many ways can the remaining digits be chosen.
The remaining digits for the given condition can be chosen in 504.
Option B: 504
What is the rule of product in combinatorics?If a work A can be done in p ways, and another work B can be done in q ways, then both A and B can be done in ways.
Remember that this count doesn't differentiate between order of doing A first or B first then doing other work after the first work.
Thus, doing A then B is considered same as doing B then A
Since 7 is already fixed and there is constraint that no two digits can be used, thus, we initially have only 10-1 = 9 digits.
For first place, we can chose 1 digit out of 9 digits in ways,
⁹C₁ = 9 ways
For second place, as one of the digit is used, thus, 1 digit out of 8 digits can be chosen in ways,
⁸C₁ = 8 ways
For third place, as two of the digits is used, only 7 digits are remaining to chose from. Thus, 1 digit out of 7 remaining digits can be chosen in ways.
⁷C₁ = 7 ways
Using product rule, we get:
Total possible number of choices for choosing digits for first, second and third position of lock with given constraints is given as
= 9 x 8 x 7
= 504 ways
Thus, The remaining digits for the given condition can be chosen in,

There are 300 different sundaes possible with the given choices of 20 ice cream flavors, 5 toppings, and 3 sizes at the make-your-own sundae bar.
To find the total number of different sundaes possible, we need to multiply the number of choices for each category: ice cream flavors, toppings, and sizes.
Number of ice cream flavors = 20
Number of toppings = 5
Number of sizes = 3
Total number of sundaes = Number of ice cream flavors × Number of toppings × Number of sizes
Total number of sundaes = 20 × 5 × 3
