ANSWER
Converges
[tex]S_{ \infty } = 68[/tex]
EXPLANATION
The guy sequence is
17 + 12.75 + 9.5625 + ...
The common ratio is:
[tex] \frac{9.5625}{12.75} = \frac{12.75}{17} = \frac{3}{4} = r[/tex]
Since
[tex] |r| < 1[/tex]
the series converges.
The sum to infinity of this sequence is :

Margin of Error is simply a range, an amount that is allowed for in case of miscalculation or change of circumstances. The margin of error is 5%.
1. Find the 5% of 3.20 = .16
2. Subtract and add .16 to 3.20 to get rid of that margin of error
3.20 + .16 = 3.36 and 3.20 - .16 = 3.04
3. 3.04 and 3.36
Answer:
b 3.04 to 3.36
Step-by-step explanation:
First we need to find 5% of 3.20
.05*3.20 = .16
To find the lower value, subtract 16 cents from 3.20
3.20-.16 = 3.04
To find the upper value, add 16 cent to 3.20
3.20 + .16 = 3.36
The range is 3.04 to 3.36

A fourth degree polynomial has real roots at 0,3 a double real root at -1 and passes through point 2,12 what is the equation for the function
Answer:
y=x^2-3x
Step-by-step explanation:
Final answer:
A fourth degree polynomial with real roots at 0, 3 and a double real root at -1 passes through the point (2, 12). The equation for the function is -2x(x - 3)(x - 3)(x + 1).
Explanation:
A fourth degree polynomial with real roots at 0, 3 and a double real root at -1 can be expressed as:
f(x) = a(x - 0)(x - 3)(x - 3)(x + 1)
To find the value of 'a', we can substitute the point (2, 12) into the equation:
12 = a(2 - 0)(2 - 3)(2 - 3)(2 + 1)
12 = -6a
a = -2
So, the equation for the function is:
f(x) = -2x(x - 3)(x - 3)(x + 1)

ben owns a older american truck. The odometer shows distance travelled in miles. On a recent trip to deliver produce for his employer, he drove 1564 miles. His employer pays him $0.89/km for the use of his own truck. How much will he be reimbursed for the use of his truck for the trip?
Answer:
$2,239.66
Step-by-step explanation:
To find the amount of reimbursement, convert miles to km by multiplying 1564 by 1.609 since 1 mile = 1.609 km.
He drive 1564(1.609)=2,516.476 km.
Multiply this distance by $0.89 per km.
2516.476(0.89)=$2,239.66

lf 4 pounds of birdseed cost
$6.95, about how much does 1 ounce
cost?
Answer:
$1.01
Step-by-step explanation:
To find the cost of one ounce of birdseed, first convert the weight to ounces (4 pounds equals 64 ounces) and then divide the total cost by the total number of ounces. The result is approximately $0.11 per ounce.
First, we need to convert the weight from pounds to ounces since there are 16 ounces in 1 pound. So, 4 pounds is equivalent to 4 × 16, which equals 64 ounces.
Now, if 4 pounds (or 64 ounces) of birdseed cost $6.95, we want to find the cost of one ounce. To do this, we divide the total cost by the total number of ounces:
$6.95 / 64{ ounces} = approximately $0.10859375 { per ounce}
This result is the cost per ounce. So, the approximation for the cost of 1 ounce of birdseed is roughly $0.11 (rounded to 2 decimal places).
Which of the following are factors of the equation when written in factored form
Answer:
B and D
Step-by-step explanation:
Given
2a² + 8a - 15 = 3a - 3 ( subtract 3a - 3 from both sides )
2a² + 5a - 12 = 0 ← in standard form
To factorise the quadratic
Consider the factors of the product of the a² term and the constant term which sum to give the coefficient of the a term, that is
product = 2 × - 12 = - 24 and sum = + 5
The factors are + 8 and - 3
Use these factors to split the a- term
2a² + 8a - 3a - 12 = 0 ( factor the first/second and the third/fourth terms )
2a(a + 4) - 3(a + 4) = 0 ← factor out (a + 4) from each term
(a + 4)(2a - 3) = 0 ← in factored form

Answer:
x = 4, y = 2
Step-by-step explanation:
Given the 2 equations
5x + 2y = 24 → (1)
5y = x + 6 → (2)
Rearrange (2) expressing x in terms of y by subtracting 6 from both sides
x = 5y - 6 → (3)
Substitute x = 5y - 6 into (1)
5(5y - 6) + 2y = 24 ← distribute and simplify left side
25y - 30 + 2y = 24
27y - 30 = 24 ( add 30 to both sides )
27y = 54 ( divide both sides by 27 )
y = 2
Substitute y = 2 into (3) for corresponding value of x
x = (5 × 2) - 6 = 10 - 6 = 4

Answer:
The value of x is 6 and -6. The smallest value of x is -6
Step-by-step explanation:
2/3 x² = 24
solving this equation for finding the value of x.
Multiply both sides by 3/2
x² = 24 * 3/2
x² = 72/2
x² = 36
Now, to find the value of x taking square root on both sides
√x² = √36
x= ±6
So, the value of x is 6 and -6. The smallest value of x is -6
Find the 11th term 64,-32,16,-8
Answer:
0.025
Step-by-step explanation:
First you need to figure out the common pattern you see. What I saw was that we are dividing something.
I looked at the 16 and -8 and thought of -2. To make sure, you can use a calculator.
So -8 is the 4th term you can go back dividing -8 with -2 until you've reached the 11th term.
I don't know if my answer is right. I wasn't being organized as I could be. It would be better if you do it again to make sure it's correct.
A bakery offers a sale price of $3.00 for 3 muffins. What is the price per dozen?
Answer:
$12 per dozen muffins
Step-by-step explanation:
3.00/3 = 1
1x = the price of one muffin
1(12) = 12
Step 1: Find what the price is per muffin. To do this you must divide $3.00 by 3 muffins (this will tell you dollar per muffin or $/muffin)
3 ÷ 3 = 1
This means that every muffin is $1
Since we know this, and we know that a dozen means 12 we can multiply 1 by 12 to find how much you would pay for a dozen muffins
12 × 1 = 12
It's $12 per dozen muffins

Alice has a photo of herself standing next to her dog. In the photo, she is 2.5 in. tall and her dog is 0.5 in. tall. Alice
is actually 66 in. tall.
How tall is her dog?
A. 13.2 in.
B. 22.0 in.
C. 26.4 in.
D. 33.0 in.
HELP ASAP PLZ!!
Answer:
a. 13,2 in.
Step-by-step explanation:
66 : 2.5 = 26.4
0.5 x 26.4 = 13.2
By creating a proportion based on the heights shown in the photo and Alice's actual height, we can calculate that Alice's dog's actual height is 13.2 inches, which is option A.
To find out how tall Alice's dog is in reality, we need to use the ratio of their heights in the photograph to determine the dog's actual height. In the photograph, Alice's height is 2.5 inches and her dog's height is 0.5 inches, while her actual height is 66 inches. This creates a ratio that we can use to calculate the dog's actual height.
First, we set up a proportion where the height of Alice in the photo is to her actual height as the height of the dog in the photo is to the dog's actual height:
2.5 inches / 66 inches = 0.5 inches / x inches
Now we solve for x, which represents the dog's actual height:
x = (0.5 inches * 66 inches) / 2.5 inches
After performing the multiplication and division, we get:
x = 13.2 inches
Therefore, the height of Alice's dog in reality is 13.2 inches, which corresponds to option A.

The length of a rectangle is eight more than twice the width. The perimeter is 64. Find the length and width
Answer:
24 and 8
Step-by-step explanation:
The formula for the perimeter of the rect. is P = 2W + 2L.
Here, L = 2W + 8, so the area formula becomes:
P = 2W + 2(2W + 8) = 64
Dividing all terms by 2 reduces this to:
W + 2W + 8 = 32, or 3W = 24, or W = 8.
Then: L = 2W + 8 = 2(8) + 8 = 24
Check: does 2W + 2L = 64 when these values for W and L are substituted?
Is 2(8) + 2(24) = 64 true? Yes
The length and width are 24 and 8 respectively.
The length of rectangle will be 8 units.
The width of rectangle will be 24 units.
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The length of a rectangle is eight more than twice the width.
The perimeter is 64.
Now,
Let the width of rectangle = x
Then, The length of rectangle = 2x + 8
Here, The perimeter is 64.
So, We get;
2 (length + width) = 64
2 (2x + 8 + x) = 64
2 (3x + 8) = 64
3x + 8 = 64/2
3x + 8 = 32
3x = 32 - 8
3x = 24
x = 8
Thus, The width of rectangle = x
= 8
Then, The length of rectangle = 2x + 8
= 2 × 8 + 8
= 24
Therefore, The length of rectangle will be 8 units.
The width of rectangle will be 24 units.

Given: E, F, Q, D∈k(O),
O ∈ ED , m∠DFQ = 10°,
m EF = 28°
Find: Angles of △EFQ
Answer:
The angles are m∠EQF=14°, m∠EFQ=90° and m∠QEF=76°
Step-by-step explanation:
Given the figure in which m∠DFQ = 10°, m∠EOF = 28°
we have to find the angles of △EFQ
m∠EOF = 28°
By theorem angle subtended at the centre is twice the angle subtended at the circumference
⇒ m∠EQF=14°
As angle ∠EFQ is the angle in the semicircle
∴ ∠EFQ=90°
In ΔEFQ, by angle sum property of triangle
m∠EFQ+m∠FQE+m∠QEF=180°
90°+14°+m∠QEF=180°
m∠QEF=180°-90°-14°=76°
Hence, m∠EFQ=90° and m∠QEF=76°
To find the missing angle in triangle △EFQ, we used the fact that the sum of angles in a triangle is always 180°. Therefore, m∠EQF is found to be 142°, making the angles of the triangle 10°, 28°, and 142°.
Explanation:This problem deals with finding the measurements of angles in a triangle. In this case, the triangle is △EFQ, and we are given that m∠DFQ = 10° and m∠EF = 28°. The sum of the angles in a triangle always equals 180°. So, the third angle, m∠EQF, can be found by subtracting the given angles from 180°.
To calculate, follow these steps:
First, add the given angles: 10° + 28° = 38°.Next, subtract the sum of the given angles from 180°: 180° - 38° = 142°.Therefore, m∠EQF = 142°. So, the angles of triangle △EFQ are 10°, 28°, and 142°.
