a) find u,
b) find uz
c) find us
Answer:
see solution below
Step-by-step explanation:
Correct question
A sequence is defined by the term-to-term rule
Un+1 = u. + 3
Given that u1 = 1,
a) find u2
b) find u3
c) find u5
a) Given the recursive formula;
Un+1 = un + 3
When n = 1;
U1+1 = U1 + 3
U2 = U1 + 3
U2 = 1 + 3
U2 = 4
b) U3 = U2 + 3
U3 = 4 + 3
U3 =7
c) U4 = U3 + 3
U4 = 7+3
U4 = 10
U5 = U4 + 3
U5 = 10 + 3
U5 = 13
Note that the question was assumed. The same calculation can be employed for nay other term

Graph the following system of inequalities.
y>1/3x-2
y <-4x-2
Graph-X represents the given set of inequalities.
What is inequality?"An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions."
Given two inequalities are:
1. y > (1/3)x - 2
If we compare it with the slope-intercept form of a line, then:
Slope = 1/3, y-intercept = - 2
Therefore, the line cuts the y-axis at x = - 2.
Here, the greater than sign indicates that the graph would be shaded down.
2. y < - 4x - 2
If we compare it with the slope-intercept form of a line, then:
Slope = - 4, y-intercept = - 2
Therefore, the line cuts the y-axis at x = - 2.
Here, the less than sign indicates that the graph would be shaded up.
Therefore, Graph-X represents the given set of inequalities.

One of the angles of a triangle is 8 deg more than 5 times another angle. If the third angle is 4 deg larger than the difference of the first two angles, find the angles.
Answer:
[tex]16^\circ, 88^\circ, 76^\circ[/tex]
Step-by-step explanation:
Given a triangle.
One of the angles is [tex]8^\circ[/tex] more than 5 times of one angle.
Third angle is [tex]4^\circ[/tex] more than the difference of two angles.
To find:
The angles.
Solution:
Let the first angle = [tex]x^\circ[/tex]
As per question statement, second angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex]
And third angle = 5[tex]x^\circ[/tex] + [tex]8^\circ[/tex] - [tex]x^\circ[/tex] + [tex]4^\circ[/tex] = [tex](4x+12)^\circ[/tex]
Using triangle sum property that the sum of all the internal angles of a triangle is always equal to [tex]180^\circ[/tex].
[tex]x+5x+8+4x+12 = 180\\\Rightarrow 10x+20=180\\\Rightarrow 10x = 160\\\Rightarrow x = 16[/tex]
Therefore, the first angle = [tex]x^\circ = 16^\circ[/tex]
The second angle = [tex]5x+8 = 5 \times 16 + 8 = 80+8 = 88^\circ[/tex]
The third angle = [tex]4x+12 = 4\times 16 + 12 = 76^\circ[/tex]
Therefore, the angles are [tex]16^\circ, 88^\circ, 76^\circ[/tex].

-5(t + 3)= -30
Solve for the variable!! Please
Answer:
[tex]\huge\boxed{t=3}[/tex]
Step-by-step explanation:
[tex]-5(t+3)=-30[/tex]
METHOD 1:[tex]-5(t+3)=-30[/tex] divide both sides by (-5)
[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]
[tex]t+3=6[/tex] subtract 3 from both sides
[tex]t+3-3=6-3\\t=3[/tex]
METHOD 2:[tex]-5(t+3)=-30[/tex] use the distributive property a(b + c) = ab + ac
[tex](-5)(t)+(-5)(3)=-30[/tex]
[tex]-5t-15=-30[/tex] add 15 to both sides
[tex]-5t-15+15=-30+15[/tex]
[tex]-5t=-15[/tex] divide both sides by (-5)
[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

Okay so I have no clue what to do on these problems lol. Can someone help explain it please? Thank you
Answer:
you use the Pythagorean theorem (a^2 +b^2 = c^2)
a^2 +17^2 = 19^2
a^2 + 289 = 361
a^2 = 72
a = (square root)72
5^2 + 13^2 = c^2
25 + 169 = c^2
194 = c^2
c= (square root)194
a^2 + 10^2 = 20^2
a^2 + 100 = 400
a^2 = 300
a = (square root) 300
5^2 + 14^2 = c^2
25 + 196 = c^2
221 = c^2
c= (square root) 221

Answer:
Answer:
x=3
Step-by-step explanation:
7−3x=−x+1
Step 1: Simplify both sides of the equation.
7−3x=−x+1
7+−3x=−x+1
−3x+7=−x+1
Step 2: Add x to both sides.
−3x+7+x=−x+1+x
−2x+7=1
Step 3: Subtract 7 from both sides.
−2x+7−7=1−7
−2x=−6
Step 4: Divide both sides by -2.

What is the largest 2-digit composite number divisible by 46?
Answer:
92
Step-by-step explanation:
its 92 because its is a 2-digit number and is considered composite because its divisible by 2, 4, 23 and 46
The largest 2-digit composite number divisible by 46 is 92 and this can be determined by using the definition of composite numbers and by arithmetic operations.
Given :
Number - 46
The following steps can be used to determine the largest 2-digit composite number divisible by 46:
Step 1 - Remember that composite numbers are those numbers that are divisible by more than two numbers.
Step 2 - The two-digit composite numbers which are divisible by 46 are 46 and 92.
Step 3 - The largest number between 46 and 92 is 92.
So, the largest 2-digit composite number divisible by 46 is 92.

9. The diagram shows a triangle inscribed in a circle with centre O.
The lengths of the shorter sides of the triangle are 6 cm and 8 cm.
Work out the area of the circle.
Use π = 3.14.
Answer:
25π
Step-by-step explanation:
let c = length of third side of triangle
since you are working with a right triangle you can find the third side by using the pythagorean theorem: 8^2 + 6^2 = c^2
64 + 36 = c^2
100 = c^2
c = 10
10 is also the diameter of the circle and radius is 5
