Step-by-step explanation:
Mr. Morris asked Rob to shovel the snow from his driveway every day that it snowed during the month of January. He agreed to pay Rob $0.01 for the first day, $0.02 for the second day, $0.04 for the third day, $0.08 for the fourth day, and so on. If it snowed for 13 days in January, how much would Mr. Morris pay Rob on the 13th day?
Do not answer if you do not know. Only good answers with explanations.
Answer:
Total amount to be paid on 13th day is $40.96.
Step-by-step explanation:
Mr. Morris pays Rob $0.01, $0.02, $0.04 ..... on 1st, 2nd , 3rd .... day respectively.
We can clearly see that the next number is becoming double of the previous value.
The above sequence of numbers are in a Geometric Progression with
First term, a = 0.01 and
Common ratio, r = 2
We have to find the total amount paid on 13th day.
We know that the [tex]n^{th}[/tex] term of a GP is given by:
[tex]a_{n} =ar^{n-1}[/tex]
Where, a is the first term of GP
r is the common ratio
We have to find the [tex]13^{th}[/tex] term of the GP as per question statement.
Putting the values in the formula above:
n = 13
a = 0.01 and
r = 2
[tex]a_{13} = 0.01 \times 2^{13-1}\\\Rightarrow 0.01 \times 2^{12} \\\Rightarrow 0.01 \times 4096\\\Rightarrow 40.96[/tex]
Total amount to be paid on 13th day is $40.96.

At the amusement park each students is given $16 dollars for food. This covers the cost of 2 meals plus $4 for snacks. how much money does the school expect each student to spend per meal. Which equation can be used to represent this situation? plz help now if u can
Answer:
16 = 2x + 4
Step-by-step explanation:
The total amount of money they are given is $16. That is split up into 2 equal groups with 4 left over. So you'd have to subtract 4 from both sides. Then divide both sides by 2. This will give you the answer to how much money they expect the students to spend on food.

Eric, Cam, and Brooke are playing a game of mini golf on a computer. The computer program for the game stores
objects in terms of I and y coordinates. All coordinate values are in meters.
The players are shooting at the hole, which is located at (3,2). After hitting their initial shots, Eric's golf ball is at
(-6,6). Cam's golf ball is at (8,-6), and Brooke's golf ball is at (10,8).
If the player whose ball is farthest from the hole should shoot next, which player should shoot next?
Choose 1 answer:
Answer:
Eric
Step-by-step explanation:
For we solve this problem, we have to determine the distance of each player to the hole using the distance formula.
D = √(x2-x1)²+(y2-y1)²
The hole for Eric is
The hole is at (3,2)
Eric's golf ball is at point (-6,6)
= √(-6-3)²+(6-2)²
= √-9²+4²
= √81+16
= √97
= 9.85 approx
The for Brooke
The hole is at (3,2)
Brooke's golf ball is at point (10,8)
= √(10-3 )²+(8-2)²
= √7²+6²
= √ 85
= 9.22 approx
Base on the two values gotten, Eric distance is more far compare to Brooke, therefore Eric should be the one to shoot next .

On the graph of f(x)=cos x and the interval [0,2π), for what value of x does f(x) achieve a minimum?
Choose all answers that apply.
0
π/4
π/2
π
3π/2
Answer:
[tex]cos(\pi)=-1[/tex]
Step-by-step explanation:
[tex]f(x)=cos (x)[/tex]
State that the values where cos x is minimum:
[tex]x=\pi +2\pi n, n\in \mathbb{Z}[/tex]
[tex]cos(0)=1\\[/tex]
[tex]$cos\left(\frac{\pi}{4} \right)=\frac{\sqrt{2} }{2} $[/tex]
[tex]$cos\left(\frac{\pi}{2} \right)=0 $[/tex]
[tex]cos(\pi)=-1[/tex]
[tex]$cos\left(\frac{3\pi}{2} \right)=0 $[/tex]
We want to see for wich values of x does f(x) = cos(x) has a minimum in the interval [0,2π), the answer is x = π
So we know that the cosine function has a maximum value of 1 and a minimum value of -1, such that:
-1 ≤ cos(x) ≤ 1
Then we want to find the value such that:
cos(x) = -1
Let's look at the graph of the cosine function, which is below. There, you can see that the minimum is at x = π.
Then the correct option is:
x = π

HOW MANY FEET GREATER IS THE CIRCUMFERENCE OF THE OUTER CIRCLE THAN IT IS OF THE THE INNER CIRCLE *ROUND TO THE NEAREST TENTH*
answer fast please!
Answer:
25.1
Step-by-step explanation:
1. Find the radius of the inner circle
(the formula for the circumference of a circle is [tex]C=2\pi r[/tex])
To find the radius of the inner circle, you would plug in the given information so that your equation looks like this:
[tex]22=2(\frac{22}{7} )r[/tex]
then solve for [tex]r[/tex]
[tex]r=3.5[/tex]
2. add [tex]4[/tex] to the radius of the inner circle
[tex]3.5+4=7.5[/tex]
3. find the circumference of the outer circle using [tex]7.5[/tex] as the radius
[tex]C=2(\frac{22}{7})7.5[/tex]
[tex]C=47.1[/tex]
4. Subtract the circumference of the inner circle from the circumference of the outer circle
[tex]47.1-22=25.1[/tex]
Why was radian such a good safety on the football team? (25 pts)
Answer: because of the translational and rotational motion of the football
Step-by-step explanation:
A kick or a well thrown football follows a projectile path while spinning. In football, creedence is given to the translational motion which is independent of the spinning rotational motion. Radian is good in analysing the path because the angle representing one radian, is such that the length of the subtended circular arc is equal to the radius of the circle.

If a wiggling string has a natural frequency of 34.5 Hz to produce 4 harmonics, what is the period of the string?
Answer:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s
Step-by-step explanation:
For this case we know the frequency associated to the 4 harmonic.
We know that by definition the frequency is the inverse of the period:
[tex] f= \frac{1}{T}[/tex]
If we solve for the period we got:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s

ANSWER: 100=5*6
100=30
HOPE IT HELPS!
Answer:
x = 3 1/3
Step-by-step explanation:
Let's go over the order of operations.
P: Parentheses
E: Exponents
M/D: Multiplication/division (in order of appearance)
A/S: Addition/Subtraction (in order of appearance)
100 = 5*(4 + 2)
Since there are values in parentheses, solve those first: 100 .= 5x(6).
Next, multiply 5x by 6. 100 = 30x.
Finally, divide each side by 30 to find the value of x. 3 1/3 = x
Therefore, the value of x is 3 1/3.
(Note: this is assuming the term "x" is a variable, and not the multiplication sign, *.)
