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:

24

Step-by-step explanation:

Answer:

Angie is thinking of the number 24.

Explanation:

24 can be divided into 8 three times & can be divided by 12 only two times.

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:

$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

Answer:

$2600 I believe

Step-by-step explanation:

Since he puts $75 in his account every week and he save his money for 24 weeks, 75 times 24= 1800 and he already had $800 in his account, so 1800+ 800= 2600

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:

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.

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:

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

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:

It is not a right triangle. It is an obtuse triangle.

Step-by-step explanation:

Since 185 is not equal to 169, the triangle with side lengths 8, 11, and 13 is not a right triangle.

We have,

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Check if this condition holds for the given triangle:

8² + 11²

= 64 + 121

= 185

But,

13² = 169

Thus,

Since 185 is not equal to 169, the triangle with side lengths 8, 11, and 13 is not a right triangle.

Answer:

x=58

Step-by-step explanation:

5x+106=7x-10

-2x = -116

x = 58

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:

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
