1) Find a formula for a sub n for the arithmetic sequence a sub 1 = 7, d = 12.
2) Write the first 5 terms of the geometric sequence a sub 1 = 2, r = 2.
Answer:
Step-by-step explanation:
nth term = a₁ + (n-1)d = 7 + (n-1)12
:::::
nth term = a₁rⁿ⁻¹ = 2×2ⁿ⁻¹ = 2ⁿ
a₁ = 2
a₂ = 4
a₃ = 8
a₄ = 16
a₅ = 32

The run is the__
change between two points on a line.
A. rising
B. horizontal
C. average
D. vertical
Answer:
Horizontal
Step-by-step explanation:
The mathematical definition of slope is very similar to our everyday one. In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run.

Step-by-step explanation:
1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal
h, l and w are known; discover V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal
S, l and w are known; discover h, V and d
h = (S - 2lw)/(2l + 2w)
V = lwh
d = √(l2 + w2 + h2)
3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal
V, l and w are known; discover h, S and d
h = V/lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal
d, l and w are known; discover h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)

Trent attaches his A+ test to the refrigerator with a circular magnet. Out of curiosity, he measures the magnet and calculates that it has a diameter of 4 centimeters. What is the magnet's area?
Answer:
12.6 cm²
Step-by-step explanation:
From the above question, the magnet is circular in shape
The area of a circle is given as:
= πr²
The area of the magnet = π × r²
Diameter = 4cm
r = Diameter/2 = 4cm/2 = 2cm
= π × (2cm)²
= 12.566370614cm²
Approximately = 12.6 cm²
The area of the magnet = 12.6cm²

Help ASAP I really need an answer I don't need links please and if you don't know that answer just don't answer
Answer:
113
Step-by-step explanation:
note: to find the circumference of a circle using the radius, you use this equation -- 2[tex]\pi[/tex]r. since the radius is 18, you make the equation 2[tex]\pi[/tex]18. that gets you 36[tex]\pi[/tex], which, if put into the calculator, is about 113.
How many solutions does this equation have?
8z − 5 = 8z
Answer:
Zero
Step-by-step explanation:
Solve the equation by subtracting 8z from both sides:
8z − 5 = 8z
-5 = 0
-5 [tex]\neq[/tex] 0
This is a false statement, because -5 is not equal to zero.
This means that there are no solutions to the equation.
So, the equation has zero solutions
Because both sides of the equation have the same variable ( they both have 8x) this equation does not have any solutions.
please please help i have three questions left for this lesson

Answer:
y = -|x -1| +2
Step-by-step explanation:
The transformation ...
-f(x -h) +k
reflects function f(x) over the x-axis, translates it 'h' units to the right and 'k' units up.
Your absolute value function is reflected over the x-axis, then translated 1 unit right (h=1) and 2 units up (k=2). Putting these values in the function, we have ...
y = -abs(x -1) +2
y = -|x -1| +2
This February only one quarter of the days had an average temperature above freezing (32 degrees). How many days in February were below freezing?
Answer:
21 days
Step-by-step explanation:
February has 28 days
28/4=7
1 quarter of 28 is 7
Since one quarter was above freezing, 3 were below freezing
3x7=21
21 days is the final answer
Answer:
21 days
Step-by-step explanation:
There are 28 days in February.
If one quarter of the days had a temperature above freezing, that means that three quarters of the days had a temperature below freezing.
Find how many days were below freezing by multiplying 28 by 3/4
28(3/4)
= 21
So, 21 days in February were below freezing.

15x – 4y = -50
3x – 2y = –16
Answer:
x=-2, y=5. (-2, 5).
Step-by-step explanation:
15x-4y=-50
3x-2y=-16
---------------
15x-4y=-50
-5(3x-2y)=-5(-16)
------------------------
15x-4y=-50
-15x+10y=80
-------------------
6y=30
y=30/6
y=5
3x-2(5)=-16
3x-10=-16
3x=-16+10
3x=-6
x=-6/3
x=-2

what is 1/3(w+18)=12 using distributive property?
Answer:
w = 18
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (w + 18) = 12 ← distribute parenthesis on left side
[tex]\frac{1}{3}[/tex] w + 6 = 12 ( subtract 6 from both sides )
[tex]\frac{1}{3}[/tex] w = 6 ( multiply both sides by 3 to clear the fraction )
w = 18

Write the Equation of the line in fully simplified slope- intercept form
Answer:
y=-6/5x-2
Step-by-step explanation:
We are given points (5,-8) and (-5,4)
Slope = m = (y₂-y₁)/(x₂-x₁) = (-8-4/(5-(-5)) = -12/10 = -6/5
Y-intercept = b = (0,-2)
Final equation: y=-6/5x-2
Answer:
y=-6/5x-2
Step-by-step explanation:
y=mx+b
Its sloping downwards, so a negative slope.
two points: (-5,4) and (5,-8)
---------------------------------------------
so first find the slope.
y2-y1 / x2-x1 <= formula
so: -8-(4) / 5-(-5)
which becomes => -12/ 10
which is 6/5 the slope is 6/5
------------------------------------------
plug this into y=mx+b, where m is the slope
so: y=6/5x+b
------------------------------------------
obviously b is the y intercept, where the line meets y
the y intercept is -2
sooooooo final answer is
----------------------------------
y=6.5x+(-2)
-----------------------------------
Negative slope, so becomes y=6/5x-2
