Answer:

The value of a[tex]_{12}[/tex] is 42

Step-by-step explanation:

The explicit formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where

∵ a[tex]_{1}[/tex] = 20 ⇒ first term

∴ a = 20

∵ d = 2 ⇒ common difference

∵ We need to find a[tex]_{12}[/tex]

∴ n = 12

→ Substitute them in the formula above

∵ a[tex]_{12}[/tex] = 20 + (12 - 1)(2)

∴ a[tex]_{12}[/tex] = 20 + (11)(2)

∴ a[tex]_{12}[/tex] = 20 + 22

∴ a[tex]_{12}[/tex] = 42

∴ The value of a[tex]_{12}[/tex] is 42

Answer:

Step-by-step explanation:

Answer:

Options B and D

Step-by-step explanation:

Let's solve each equation:

x-3x=-2x+4

-2x=-2x+4

0=4

No solutions, so A is wrong

x-1/3(3x)=0

x-(3x/3)=0

x-x=0

0=0

Infinitely many solutions, so B is correct

1/3x-3=4+2x

1/3x=7+2x

-5/3x=7

x=-21/5

One solution, so C is incorrect

3x+2-1/3(3x)=2+2x

3x+2-(3x/3)=2+2x

3x+2-x=2+2x

2x+2=2+2x

2x=2x

0=0

Infinitely many solutions, so D is correct

x-1/3x+2=0

2/3x+2=0

2/3x=-2

x=3

One solution, so E is incorrect

As you can see, when both sides of the equations are equal to each other such as 0=0 and x=x, you'll always have infinitely many solutions. Therefore, options B and D are correct

Answer:

Answer:

$100

Step-by-step explanation:

Simple Interest formula is given as:

A = P(1 + rt)

Where

A = Amount after t years

P = Principal = Initial Amount Invested = $2000

r = Interest rate in t years = 5%

t = time = 1 year

A = 2000(1 + (0.05 × 1)) = 2100

A = $2,100.00

The Amount after 1 year = $2100.00

The Simple Interest is calculated as

= A - P

= $2100 - $2000

= $100

Therefore, after 1 year her investment would have paid $100

GIVE ME BRAINLIEST???? THIS TOOK A WHILE :(

Answer:

x ≈ 10.9

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan38° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{14}[/tex] ( multiply both sides by 14 )

14 × tan38° = x , then

x ≈ 10.9 ( to the nearest tenth )

Answer:

39°

Step-by-step explanation:

The equation is

3h+72+8h+95=90

11h+167=90

11h=-77

h=-7

So RGK=

8.-7+95

Answer:

Step-by-step explanation:

triangle: a+b>c. If two lengths are put together, and equals more than the length of the third side, then it's a triangle

right triangle: a2+b2=c2 if the square of the two lengths equal the square of the third, then it's a right triangle

acute triangle: a2+b2>c2 if the square of the two lengths are greater than the square of the third it's acute

obtuse triangle:a2+b2<c2 if the square of the two lengths are less than the square of the third it's obtuse

Hello!

[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]

[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]

Find the inverse by swapping the x and y variables:

[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]

Begin simplifying. Multiply both sides by 4y - 5:

[tex]x(4y - 5) = 2y + 2[/tex]

Start isolating for y by subtracting 2 from both sides:

[tex]x(4y - 5) -2 = 2y[/tex]

Distribute x:

[tex]4yx - 5x - 2 = 2y[/tex]

Move the term involving y (4yx) over to the other side:

[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]

Factor out y and divide:

[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]

Use this equation to evaluate [tex]f^{-1}(3)[/tex]

[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]

Answer:

x = ± [tex]\sqrt{20}[/tex]

Step-by-step explanation:

Given

x² = 20 ( take the square root of both sides )

x = ± [tex]\sqrt{20}[/tex]

which can be simplified to

x = ± 2[tex]\sqrt{5}[/tex]

[ ± means plus or minus ]

Answer:

3.5

Step-by-step explanation:

If you get more like this just divide the big triangle to the small one. on the same lengths. Example: on this one do 14/4 = 3.5, 10.5/3 = 3.5, 21/6 = 3.5

Hope this helps! :)

Answer:

8

Step-by-step explanation:

To find a slope for a line that is perpendicular to another line, you simply need to take the negative reciprocal of the the original line's slope.  In this case we are already given the slope as the coefficient to x: -1/8.  The negative reciprocal of that is 8/1, or just 8.

Answer:

= desaster

Step-by-step explanation:

Answer: m = 1/2

Step-by-step explanation: Let's use the graphing method.

To find the slope of the line using the graphing method,

we first set up a coordinate system.

Next, we plot our two points, (0, 0), which we label point A, and (2, 1),

which we label point B, and we graph our line, as shown below.

Now just graph the line through the two points.

Now, remember that the slope, or m, is equal to the

rise over run from point A to point B.

To get from point A to point B, we rise 1 unit and run 2 units.

So our slope, or rise over run, is 1/2.

Answer:

18ft

Step-by-step explanation:

2+3+7 = 12 (this means that 108ft is [tex]\frac{12}{12}[/tex])

The shortest side would be [tex]\frac{2}{12}, or \frac{1}{6}[/tex] of 108ft

To find this, we divide 108 by the denominator (6) to get 18ft

We would usually multiply this by the numerator when finding a fraction of an amount, but as the numerator is 1, the answer would stay as 18ft.

Answer:

no

Step-by-step explanation:

y = -2x + 16

-2 = -2(10) + 16

-2 = -20 + 16

-2 = -4

which is wrong

Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.

y = -2x + 16 > -2 = -2(10) + 16

Now, solve.

-2 = -2(10) + 16 > -2 = -20 + 16  - Start by multiplying out parenthesis.

-2 = -20 + 16 > -2 = -4 - Add.

-2 = -4

The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.
