Answer:

Step-by-step explanation:

so by "exact" they mean leave in the [tex]\sqrt{x}[/tex] parts.... sooo

they tell us the Hypotenuse  ( Hyp) and one  angle and want that side Opposite ( Opp)  of the angle... sooo use the mnemonic

SOH CAH TOA  

to help remember how the sin , cos, and tan functions fit on a triangle

there problems b/c easy A's when you get this.  :P so learn it, know it, live it  :D

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

now look at which one of the above formulas have the things we know and want to find

Sin looks like a good choice b/c it's got  Opp, which we want to find, and Hyp which we know and also an angle which we can plug into the function

Sin(45) = Opp / 6

see how I got that?

[tex]\sqrt{2}[/tex] / 2 = Opp / 6

6 ( [tex]\sqrt{2}[/tex] / 2 ) = Opp

3[tex]\sqrt{2}[/tex]  = Opp

the problem says leave it exact.. so don't try to reduce [tex]\sqrt{2}[/tex]  just leave it

there is  your answer

X  = 3[tex]\sqrt{2}[/tex]

Answer:

B. 2x(x + 3)(2x – 1)

Step-by-step explanation:

A. 2(x + 3)(2x – 1)

= (2x + 6)(2x - 1)

= 4x² - 2x + 12x - 6

= 4x² + 10x - 6

B. 2x(x + 3)(2x – 1)

= (2x² + 6x)(2x - 1)

= 4x³ - 2x² + 12x² - 6x

= 4x³ + 10x² - 6x

C. 2x(x – 3)(2x – 1)

= (2x² - 6x)(2x - 1)

= 4x³ - 2x² - 12x² + 6x

= 4x³ - 14x² + 6x

D. 2(x – 3)(2x + 1)

= (2x - 6)(2x + 1)

= 4x² + 2x - 12x - 6

= 4x² - 10x - 6

The completely factored form of 4x3 + 10x2 – 6x is 2x(x + 3)(2x – 1)

Answer:

14.8%

Step-by-step explanation:

Given data

Initial income=47

Final income=40

The change= 47-40

=7

Hence the percent increase is

% increase= Change/ initial*100

% increase= 7/47*100

% increase=0.148*100

% increase=14.8%

Answer:

Mutually Exclusive

Dependent

Step-by-step explanation:

Given that both events cannot occur at the same time, that is "both dice cannot be odd (event A) if at least one of the dice is even (event B).

Hence, this is MUTUALLY EXCLUSIVE.

Also, given the fact that the occurrence of one event (event A) affects the probability of the other (event B).

Hence, this is DEPENDENT.

Answer:

The answer is 13 1/8ft3

Explanation:

Substitute into the formula:

Volume = 3 1/2 x 2 1/2 x 1 1/2

= 7/2 x 5/2 x 3/2

= 105/8

= 13 1/8 ft3

Equation: 35.60 = 2.60 + 3x

It was 11 miles

Step-by-step explanation:

35.60 = 2.60 + 3x

3x = 33

x = 11

The linear function for the fare is:

[tex]F(x) = 2.6 + 3x[/tex]

Solving the equation, it is found that the taxi ride was of 11 miles.

A linear function for a cost considering a distance of x miles has the following format:

[tex]F(x) = F(0) + ax[/tex]

In which

In this problem:

The function is:

[tex]F(x) = 2.6 + 3x[/tex]

Fare of $35.60, thus [tex]F(x) = 35.60[/tex] and we solve for x to find the number of miles.

[tex]35.6 = 2.6 + 3x[/tex]

[tex]3x = 33[/tex]

[tex]x = \frac{33}{3}[/tex]

[tex]x = 11[/tex]

There were 11 miles in the taxi ride.

The denominator of the first term is a difference of squares, such that

4a ² - b ² = (2a)² - b ² = (2a - b) (2a + b)

So you can write the fractions as

(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)/(2a + b)

Multiply through the second fraction by 2a - b to get a common denominator:

(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)²/((2a + b) (2a - b))

((4a ² + b ²) - (2a - b)²) / ((2a - b) (2a + b))

Expand the numerator:

(4a ² + b ²) - (2a - b)²

(4a ² + b ²) - (4a ² - 4ab + b ²)

4ab

So the original expression reduces to

4ab / ((2a - b) (2a + b))

or

4ab / (4a ² - b ²)

upon condensing the denominator again.

Step-by-step explanation:

5n+3= -10

5n = -13

n = -13/5

= -2.6

question is integer

so answer is -2

The smallest integer n is -2

An integer is colloquially defined as a number that can be written without a fractional component.

In mathematics a linear inequality is an inequality which involves a linear function. A linear inequality contains one of the symbols of inequality.

Given,

5n + 3 > -10

Consider

5n + 3 = -10

5n = -10-3

5n = -13

n = [tex]\frac{-13}{5} =-2.6[/tex]

Therefore the smallest integer n≅ -2

Hence, the smallest integer n is -2

Answer and Step-by-step explanation:

Since we know that the triangles are similar, we can find the value of x. It appears that the lighter triangle is dilated to be smaller than the darker triangle.

So, We would divide 48 by 6 to find the scale factor.

48 divided by 6 is 8.

Now, we divide 56 by 8 to find x.

56 divided by 8 is 7.

x is equal to 7.
