Answer:

B. The graph curves away from its sum

Step-by-step explanation:

A convergent infinite geometric series, the graph of the series curves away from the sum, the correct option is B.

A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.

The standard equation for geometric series is

Tₙ = a₁ rⁿ⁻¹

The sum of an infinite geometric series is given by

S = a₁/(1-r)

where a₁ is the first term and r is the common ratio.

The graph of an infinite series curves away from its sum.

Answer:

[tex]5x + 2y = - 11 - - - (a) \\ 3x + 2y = - 9 - - - (b) \\ (a) - (b) : \\ 2x + 0y = - 2 \\ x = - 1 \\ (3 \times - 1) + 2y = - 9 \\ - 3 + 2y = - 9 \\ 2y = - 6 \\ y = - 3 \\ { \boxed{x = - 1}} \\ { \boxed{y = - 3}}[/tex]

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given the 2 equations

5x + 2y = - 11 → (1)

3x + 2y = - 9 → (2)

Subtract (2) from (1) term by term to eliminate y

2x = - 2 ( divide both sides by - 2)

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (1)

5(- 1) + 2y = - 11

- 5 + 2y = - 11 ( add 5 to both sides )

2y = - 6 ( divide both sides by 2 )

y = - 3

solution is (- 1, - 3 )

Answer:

m = 2

Step-by-step explanation:

W=10+2t has the form y = mx + b, the slope-intercept form.  Comparing

y = b + mx to

w = 10 + 2t

we see that the slope, m, is 2.  This signifies that the baby gains 2 pounds per month shortly after birth.

Step-by-step explanation:

According to the graph, f(-8)=-8

Answer:

D) 100% Positve

Step-by-step explanation:

You would choose the second option (y=1/3x) because the slope would be 1/3. Think of the slope as your directions, you go up 1 over to the right 3 times. Since the y-intercept is 0, you don't have to add anything at the end.

Hope this answer makes sense.

Step-by-step explanation: If we want to put this in standard form, we first want to add 2x² to both sides of the equation to get 2x² + 5x - 17 = 0.

Notice that I have set up the left side of the equation in descending order of powers. In other words, first the x² term, then the x term, then the constant term.

Given:

[tex]\Delta LMN\sim \Delta LRS[/tex]

To find:

The value of x.

Solution:

We have,

[tex]\Delta LMN\sim \Delta LRS[/tex]

We know that the corresponding sides of similar triangles are proportional. So,

[tex]\dfrac{LM}{LR}=\dfrac{LN}{LS}[/tex]

[tex]\dfrac{18}{2x-18}=\dfrac{30}{10}[/tex]

[tex]\dfrac{18}{2x-18}=3[/tex]

[tex]18=3(2x-18)[/tex]

Using distributive property, we get

[tex]18=3(2x)-3(18)[/tex]

[tex]18=6x-54[/tex]

[tex]18+54=6x[/tex]

[tex]72=6x[/tex]

Divide both sides by 6.

[tex]\dfrac{72}{6}=x[/tex]

[tex]12=x[/tex]

Answer:

hope this helps you out :)

Step-by-step explanation:

Hello! x = 24 This is a complementary angle so it will add up to 90 degrees in total so 24 × 3 = 72 and 72 - 6 = 66 and 66 + 24 = 90 so x = 24 HOPE THAT HELPS!

Answer:

X = 24

Step-by-step explanation:

so you will have to add all the angles and get 90

3x - 6 +x=90

4x =96

x=24

check your answer.

3 x 24

72 -6 = 66

66 +24 = 90

Answer:

A.    29 feet

Step-by-step explanation:

Use cos to find the hypotenuse

cos  = adj/hp

0.64 = 20/hyp

hyp = 20/0.64

hyp = 31.25

---------------------------

Use Pythagorean Theorem to find the height of tree above eyes

a² + b² = c²

a² + 20² = 31.25²

a² = 31.25² - 20²

a² = 576.5625

a = 24  (to the nearest foot)

-------------------------------

Finally add in the eye height

h = 24 + 5

h = 29 feet

Answer:

A. 29 feet

Answer:

6x² + 12y² + 17xy - 25xz

Step-by-step explanation:

(2x + 3y) (3x + 4y - 5z)

= 6x² + 8xy - 10xz + 9xy + 12y² - 15yz

= 6x² + 12y² + 8xy + 9xy - 10xz- 15yz

= 6x² + 12y² + xy (8 + 9) - xz (10 + 15)

= 6x² + 12y² + 17xy - 25xz
