Determine whether the sequence is arithmetic or geometric.
Sequence 1: 32, 16, 0, –16, ...
Sequence 2: 32, 16, 8, 4, ...
Which of the following statements are true regarding Sequence 1 and Sequence 2.
Answer:
Sequence 1 is arithmetic, sequence 2 is geometric.
Step-by-step explanation:
Sequence 1 is being subtracted by 16 each time, so it is arithmetic.
Sequence 2 is being divided by 2 each time, so it is geometric.
Both, sequence 1 and 2, have terms 32 and 16.

Answer:
A: 46 meters at 3 seconds
B: 0 meters at 6.033 seconds
C. It depends where the tree is
D. 6.033 seconds
Step-by-step explanation:
A. To find max height, we need to find the vertex.
We can do this by using vertex from y=a(x-h)+k for y=a^2+b^2+c^2
h(t) = -5t^2+30t+1
h(t)+45 = - 5x^2+30x+45+1
h(t)+45= -5(x^2-6x-9)+1
h(t)+45 = -5(x-3)^2+1
h(t) = -5(x-3)^2+46
Hence, the max height is 46 at 3 seconds
B. The minimum height is 0 meters because of the problem
C. It depends because the parabola intersects x=10 in 2 places meaning that you need the tree to be in either of these two places to intercept the horseshoe
D. -5x^2+30x+1=0
5x^2-30x-1=0
x= (30+-sqrt(30^2-4*5*-1))/2*5
x=(30+-sqrt920)/10
x=3+-2sqrt230/10
x=3+-sqrt230/5
This means that x = -0.033 or 6.033. Negative value doesn't make sense so it's 6.033 seconds
What is the equation in vertex form of the quadratic function with a vertex at (-1,-4) that goes through (1,8)?
Answer:
G
Step-by-step explanation:
vertex formula = a(x-h)^2 + k
vertex is (h, k) so (-1, -4) means
y = a(x+1)^2-4
passes through (1, 8) so when x = 1 and y = 8
8 = a(1+1)^2-4 = 4a - 4
4a = 4
a = 1

what is the sum of the interior angles ?
Answer:The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

The angle on the protractor is 113 degrees, which makes it an obtuse angle.
Obtuse angle is any angle greater than 90° and the angle shown is 133°
The test scores of five students for the first two test of the semester are shown in the table below.
Answer:
A
Step-by-step explanation:
Take test score from Test 1 and add them all together and divide by the number of test
ex) 77+82+69+85+93=406
406/5= 81.2
Then repeat with Test 2
ex) 75+76+71+68+72=362
362/5= 72.4
Therefore the MAD of Test 1 > MAD of Test 2
the answer is A.
Step-by-step explanation:
Add the test scores of the first test together then add the test scores of the second test together then compare and contrast.
Plz help solve this please and thx u

If the graph is reflected across the y-axis, what will be the equation of the new graph?
a) y=-3^-x+1
b) y=3^-x+1
c) y=-3^x-1
d) y=-3^x+1
Answer:
[tex] \displaystyle b)y = { 3}^{ - x} + 1[/tex]
Step-by-step explanation:
we are given a exponential function
[tex] \displaystyle y = {3}^{x} + 1[/tex]
we want to figure out the equation of the new graph reflected across the y-axis
remember that,
[tex] \rm\displaystyle (x,y) \xrightarrow{ \text{ reflection over y - axis}}( - x,y)[/tex]
let y be [tex]3^x+1[/tex] so,
[tex] \rm\displaystyle (x,y) \xrightarrow{ \text{ reflection over y - axis}}( - x, {3}^{ - x} + 1 )[/tex]
hence,
the equation of the new graph
[tex] \displaystyle y = { 3}^{ - x} + 1[/tex]
Ms. Edwards can spend, at most, $250 on new books for the school library. She will buy a reference book on birds for $30 and a reference book on the planets for $14.95. Let x represent the amount of money Ms. Edwards can spend on other books. Write an inequality that correctly describes this situation.
Answer:
x ≤ 205.05
Step-by-step explanation:
x = dollar amt remaining for other books
30 + 14.95 + x ≤ 250
44.95 + x ≤ 250
x ≤ 205.05
x ≤ $205.05 is an inequality that correctly describes this situation.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Let's use x to represent the amount of money Ms. Edwards can spend on other books.
We know that Ms. Edwards can spend at most $250 in total and that she will already spend $30 + $14.95 = $44.95 on the reference books on birds and planets.
Therefore, the amount she has left to spend on other books is:
x = $250 - $44.95
x = $205.05
Ms. Edwards can spend up to $205.05 on other books.
To write this as an inequality, we can use the less than or equal symbol since Ms. Edwards cannot spend more than $205.05:
x ≤ $205.05
Therefore, the inequality that correctly describes this situation is:
x ≤ $205.05

The angle of inclination from the base of skyscraper A to the top of skyscraper B is approximately 10.9 degrees. If skyscraper B is 1425 feet tall, how far apart are the two skyscrapers? Assume the bases of the two buildings are at the same elevation.
Answer:
269.46
Step-by-step explanation:
sin(theta) = opposite / adjacent
adjacent = opposite / sin(theta)
adjacent = 1425*sin(10.9)
adjacent = 269.4610063

Mateyo is building a rectangular prism with a volume of 1000 cubic units. The height of the prism is 10 units. Mateyo claims that the base of the prism must be a square. Draw a base for th rectangular prism that shows that Mateyo is not correct. Remember to label the units.
Answer:
See attachment for drawing
Step-by-step explanation:
Given
[tex]Volume = 1000[/tex]
[tex]Height = 10[/tex]
Required
Drawing that proves Mateyo wrong
First, calculate the base area
[tex]Volume = Base\ Area * Height[/tex]
This gives:
[tex]1000= Base\ Area * 10[/tex]
Divide both sides by 10
[tex]100= Base\ Area[/tex]
Rewrite as:
[tex]Base\ Area = 100[/tex]
The base area is calculated as:
[tex]Base\ Area = Length * Width[/tex]
So, we have:
[tex]Length * Width = 100[/tex]
Mateyo's claim can be interpreted as:
[tex]Length = Width = 10[/tex]
However, there are other possible cases such that:
[tex]Length \ne Width[/tex]
For instance:
[tex]Length = 20[/tex]
[tex]Width = 5[/tex]
