Answers

The sum of the first 75 terms of the sequence is -5.068*10^34

Given the following geometric sequence

[tex]a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)[/tex]

The sum of the nth term of the GP is expressed as;

[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]

a = -1/3

n = 75

r = a₂/a₁

a₂ = -3a₁

a₂ = -3(-1/3)

a2 = 1

r = 1/(-1/3)

r = -3

Substitute the given values in the formula;

[tex]S_n = \frac{-1/3(1-3^{75})}{1-(-3)}\\S_{75} = \frac{-1/3(3^{75}-1)}{1+3} \\S_{75} = \frac{-1/3(6.082 \times 10^{35}-1)}{4}\\S_{75} = \frac{-1/3(6.082 \times 10^{35})}{4}\\S_{75} = -0.5068 \times 10^{35}\\S_{75} = -5.068 \times 10^{34}\\[/tex]

Hence the sum of the first 75 terms is -5.068*10^34

Answers

Answer:

A)Rhombus

Lollllllllll

Answer:

A

Step-by-step explanation:

Squares have 90 degree angles, not 60.

Can a rhombus be inscribed in a circle? Why or why not?

A.)Yes, any rhombus can be inscribed in a circle, because the consecutive angles of a rhombus are congruent.
B
Yes, a square is the only rhombus that can be inscribed in a circle, because the opposite angles of a square are supplementary

C. No, no parallelogram can be inscribed in a circle, because the opposite angles are not necessarily congruent.

D. No; no rhombus can be inscribed in a circle, because the opposite angles are not necessarily supplementary

Answers

Answer:

b

Step-by-step explanation:

it isn't c because theres a theorem that says that opposite angles in a parallelogram are congruent

it isn't d because if the opposite angles are 90 and 90 they are supplementary

Answers

Answer:

The answer is 55 degrees.

Step-by-step explanation:

As shown by the red box on the angle, the angle shown is a right angle and is 90 degrees. Because we know the total angle measure, we can subtract the 31 degree angle from the 90 degree angle, which leaves us with 59 degrees for the second angle. This second angle equals (x+4). We then solve for x by setting up the equation 59= x+4. Subtract 4 from both sides and you are left with 55 degrees for x.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

On Monday, Homeroom 104 turned in 64 canned goods. This is 17 less than the number of canned goods Homeroom 106 turned in.

Let c be the total number of canned goods in Homeroom 106. Then the equation is written as,

64 - c = 17

The equation that represents the total number of canned goods in Homeroom 106 on Monday will be 64 - c = 17. Then the correct option is B.

Write an exponential model given the points ( 7, 12 ) and ( 8, 25 ). Round to the nearest hundredth.

Answers

Answer:

The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].

Step-by-step explanation:

The exponential model can be modelled by the following mathematical expression:

[tex]y = A\cdot e^{B\cdot x}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]A, B[/tex] - Coefficients.

If we know that [tex](x_{1}, y_{1}) = (7,12)[/tex] and [tex](x_{2}, y_{2}) = (8,25)[/tex], then we get the following system of equations:

[tex]A\cdot e^{7\cdot B} = 12[/tex] (2)

[tex]A\cdot e^{8\cdot B} = 25[/tex] (3)

If we divide (3) by (2), we calculate the value of [tex]B[/tex]:

[tex]e^{B}=\frac{25}{12}[/tex]

[tex]B = \ln \frac{25}{12}[/tex]

[tex]B \approx 0.734[/tex]

And by (2), we determine the value of [tex]A[/tex]:

[tex]A = 12\cdot e^{-7\cdot B}[/tex]

[tex]A = 0.0704[/tex]

The exponential model is [tex]y = 0.07\cdot e^{0.73\cdot x}[/tex].
