The nth term of a certain sequence is given as Un=(4-n)^2-1. Write down the first five terms of the sequence
The first five term of the sequence is as follows:
first term = 8second term = 3Third term = 0fourth term = -1fifth term = 0What is a Sequence?A sequence is an ordered list of numbers . Therefore,
nth term = (4 - n)² - 1where
n = number of term
let's find the first 5 term as follows:
first term = (4 - n)² - 1 = (4 - 1)² - 1 = 8second term = (4 - n)² - 1 = (4 - 2)² - 1 = 3Third term = (4 - n)² - 1 = (4 - 3)² - 1 = 0fourth term = (4 - n)² - 1 = (4 - 4)² - 1 = -1fifth term = (4 - n)² - 1 = (4 - 5)² - 1 = 0learn more on sequence here: https://brainly.com/question/14147167
ABCD is an isosceles trapezoid with legs AB and CD and with base BC. If AB=6z - 5 and BC = 7z +4 and CD = 4z +3
Answer:
Step-by-step explanation:
As it is an isosceles trapezoid,
AB = CD
6z - 5 = 4z + 3
To find the value of z, isolate z.
Add 5 to both sides
6z = 4z + 3 + 5
6z = 4z + 8
Subtract 4z from both sides
6z - 4z = 8
2z = 8
Divide both sides by 2
z = 8/2
z = 4
AB = 6z - 5
= 6*4 - 5
=24 - 5
AB = 19
CD = 4z + 3
= 4*4 +3
= 16 +3
CD = 19
BC = 7z + 4
= 7*4 + 4
= 28 + 4
BC = 32
6. If the mean of A and B is 20, the mean of B and C is 24 and the mean of A, B and C is 18. What is the mean of A and c?
Answer:
10
Step-by-step explanation
[tex]\frac{a+b}{2}=20\\\frac{b+c}{2}=24\\ \frac{a+b+c}3}=18\\[/tex]
20x2 = 40 -> a+b=40
24x2 = 48 -> b+c=48
18x3 = 54 -> a+b+c=54
solve the equations...
a=6
b=34
c=14
a+c/2 = 6+14/2 = 10

Answer:
Option D
Step-by-step explanation:
Hello!
Recall the quadratic equation: [tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}[/tex]
Remember that a quadratic equation is written in the form [tex]ax^2 + bx + c\\[/tex]
So:
a = 2b = 5c = -1Plug the values in and solve:
[tex]x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{-5\pm\sqrt{5^2 - 4(2)(-1)}}{2(2)}$\\\\x = $\frac{-5\pm\sqrt{25 +8}}{2(2)}$\\\\x = $\frac{-5\pm\sqrt{33}}{4}[/tex]
This would be [tex]\boxed{\text{Option D}}[/tex]
Yolanda is driving on a highway. She uses one gallon of gas every 20 miles she drives. The distance, D (in miles), she travels on g gallons of gas is given by the
following
D=20g
How far does Yolanda drive if she uses 5 gallons of gas?
Answer:
1g=20d so 5g=100d
Step-by-step explanation:
If it is 20 MPG, then, to find it for 5 gallons of gas, we have to multiply 20 by it. So, we have to do - 20x5
20x5=100
So hence, Yolanda drives 100 miles on the highway using 5 gallons of gas.

What is the solution to the equation?
5(8 + 7) = 5•x + 5•7
Answer:
x = 8
Step-by-step explanation:
5( 8 + 7 ) = 5 ⋅ x + 5 ⋅ 7
Add 8 and 7 to get 15.
5 × 15 = 5x + 5 × 7
Multiply 5 and 15 to get 75.
75 = 5x + 5 × 7
Multiply 5 and 7 to get 35.
75 = 5x + 35
Swap sides so that all variable terms are on the left-hand side.
5x + 35 = 75
Subtract 35 from both sides.
5x = 75 − 35
Subtract 35 from 75 to get 40.
5x = 40
Divide both sides by 5.
x = [tex]\frac{40}{5}[/tex]
Divide 40 by 5 to get 8.
x = 8
