[tex]sin(x) =\±\frac{\sqrt{2}}{2}[/tex]

[tex]tan(x) =\±\sqrt{2}[/tex]

Step-by-step explanation:

By definition we know that:

[tex]sin ^ 2 (x) = 1-cos ^ 2 (x)\\\\tan (x) = \frac{sin(x)}{cos (x)}[/tex]

in this case we know that

[tex]cos(x) =\frac{1}{2}[/tex]

So how:

[tex]sin ^ 2(x) = 1-cos ^ 2(x)[/tex]

If she uses a $100 bill to pay for the pumpkins, then the amount of change that she receives will be $ 32.5.

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

The line plot shows the weights of pumpkins available at a farm stand. The pumpkins cost $0.30 per pound. A baker purchases all of the pumpkins to make pies.

Then the weight of all the pumpkins will be

→ 6 x 3 + 8 x 5 + 9 + 10 x 7 + 12 x 4 + 13 x 2 + 14

→ 225 pounds

Then the amount of money of 225 pounds will be

→ 225 x 0.3

Answer:  [tex](f/g)(x)=\frac{2x}{x+5}[/tex]

Step-by-step explanation:

Given the function f(x):

[tex]f(x)=4x^2+6x[/tex]

And the function g(x):

[tex]g(x)=2x^2+13x+15[/tex]

To find [tex](f/g)(x)[/tex] you need to divide the function f(x) by the function g(x).

Therefore, knowing this, you get:

[tex](f/g)(x)=\frac{4x^2+6x}{2x^2+13x+15}[/tex]

You can simplify the numerator by factoring out 2x:

[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+13x+15}[/tex]

 You have to simplify the denominator:

 Rewrite the term 13x as a sum of two terms whose product be 30:  

[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+(10+ 3)x+15}[/tex]

Apply Distributive property:

[tex](f/g)(x)=\frac{2x(2x+3)}{2x^2+10x+ 3x+15}[/tex]

Make two groups of two terms:

[tex](f/g)(x)=\frac{2x(2x+3)}{(2x^2+10x)+ (3x+15)}[/tex]

Factor out 2x from the first group and 3 from the second group:

[tex](f/g)(x)=\frac{2x(2x+3)}{(2x(x+5))+ 3(x+5)}[/tex]

Factor out (x+5):

[tex](f/g)(x)=\frac{2x(2x+3)}{(2x+3)(x+5)}[/tex]

Simplifying, you get:

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

ANSWER

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

where

[tex]x \ne - \frac{3}{2} \: or \: x = - 5[/tex]

EXPLANATION

The given functions are:

[tex]f(x) = 4 {x}^{2} + 6x[/tex]

and

[tex]g(x) =2 {x}^{2} + 13x + 15[/tex]

We want to find ,

[tex]( \frac{f}{g} )(x) = \frac{f(x)}{g(x)} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{4 {x}^{2} + 6x }{2 {x}^{2} + 13x + 15} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{2{x}^{2} + 10x +3x + 15} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{2{x}(x + 5) +3(x + 5)} [/tex]

[tex]( \frac{f}{g} )(x) = \frac{2x(2x + 3) }{(2x + 3)(x + 5)} [/tex]

We cancel out the common factors to get:

Answer:

343.7 ft

Step-by-step explanation:

The wire is anchored 190 -13 = 177 ft from the ground. That distance is opposite the given angle (31°). The measure you want is the hypotenuse of the triangle with that side and angle measures.

The mnemonic SOH CAH TOA reminds you that the relation between the opposite side, hypotenuse, and angle is ...

Sin(angle) = Opposite/Hypotenuse

Filling in the given information, you have ...

sin(31°) = (177 ft)/hypotenuse

Solving for hypotenuse gives

hypotenuse = (177 ft)/sin(31°) ≈ 343.7 ft

The length of the guy wire should be 343.7 ft.

To find the length of the guy wire attached 13 feet from the top of a 190-foot tall tower at an angle of 31° with the ground, we can use the sine function and trigonometry. The length of the guy wire is approximately 380.8 feet.

To find the length of the guy wire, we can use trigonometry. The guy wire, the height of the tower, and the distance from the top of the tower to the attachment point form a right triangle. We can use the sine function to find the length of the guy wire: sin(31) = height of the tower / length of the guy wire. Rearranging the equation gives us length of the guy wire = height of the tower / sin(31). Plugging in the values, we get length of the guy wire ≈ 190 / sin(31) ≈ 380.8 feet. Therefore, the guy wire should be approximately 380.8 feet long.

Answer:

19.87 Pizzas are left

Step-by-step explanation:

To solve, just take 35 the number of starting pizzas and then subtract the number pizzas both of them consumed. So, 35 - 6.8 given 4/5 converts to 0.8 this leaves use with Bob's pizza consumption only at 28.2 pizza's left. Next, we are going to take 28.2 - 8.33 given 1/3 is .3333 repeating this then gives us the answer with having 19.87 pizzas left - although if it asks how many whole pizzas you would say 28 given you can't have .87 of a pizza.

A fraction is a way to describe a part of a whole. The amount of pizza left is 19 13/15.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given the total number of pizzas is 35. Also given, Bob eats 6 4/5 pizzas and Dave eats 8 1/3 pizzas. Therefore, the amount of pizza both together eat are,

Amount of pizza Bob and Dave eat = 6 4/5 + 8 1/3

                                                           = 34/5 + 25/3

                                                           = 102/15 + 125/15

                                                           = (102+125)/15

                                                           = 227/15

Amount of pizza left = 35 - 227/15

                                  = (525 - 227)/15

                                  = 298/15

                                  = 19 13/15

Hence, the amount of pizza left is 19 13/15.

Answer:

The first choice is correct;

(-∞,∞)

Step-by-step explanation:

We have been given the following functions;

[tex]f(x)=x^{2}-1\\\\g(x)=2x-3[/tex]

We are to determine the domain of (fog)(x).

The composite function, (fog)(x) is obtained by substituting g(x) in place of x in the function f(x);

(fog)(x) = f[g(x)] = [tex](2x-3)^{2}-1[/tex]

Clearly the function will be defined everywhere on the number line since it has no undefined points or domain constraints. The domain is thus;

(-∞,∞)

For this case we have the following functions:

[tex]f (x) = x ^ 2-1\\g (x) = 2x-3[/tex]

We must find [tex](f_ {0} g) (x):[/tex]

By definition of composite functions we have to:

[tex](f_ {0} g) (x) = f (g (x))[/tex]

So:

[tex](f_ {0} g) (x) = (2x-3) ^ 2-1\\(f_ {0} g) (x) = 4x ^ 2-12x + 9-1\\(f_ {0} g) (x) = 4x ^ 2-12x + 8[/tex]

Final answer:

The actual distance the Patel family will travel from Smithville to Clarksville is approximately 282.66 miles.

Explanation:

The scale on the map is 12 inches equals 4 miles. To find the actual distance the Patel family will travel from Smithville to Jonesville, we can set up a proportion:

12 inches / 4 miles = 334 inches / x miles

Cross multiplying, we get:

12x = 1336

Dividing both sides by 12, we find that x = 111.33 miles. So, the Patel family will travel approximately 111.33 miles from Smithville to Jonesville.

Similarly, to find the actual distance they will travel from Jonesville to Clarksville, we can set up another proportion:

12 inches / 4 miles = 514 inches / y miles

Cross multiplying, we get:

12y = 2056

Dividing both sides by 12, we find that y = 171.33 miles. So, the Patel family will travel approximately 171.33 miles from Jonesville to Clarksville.

Therefore, the total actual distance the Patel family will travel by the time they reach Clarksville is approximately 111.33 miles + 171.33 miles = 282.66 miles.

Answer: B

Step-by-step explanation: The Answer is B. 30 Sides.

The number of sides of the regular polygon each interior angle measuring 168° is 30. Thus, the correct option is B.

A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The measure of interior angles of a regular polygon is given by the formula,

[tex]\text{Measure of an interior angle} = \dfrac{(n-2) \times 180^o}{n}[/tex]

where n is the number of sides in the polygon.

Since it is given that measure of an interior angle of the polygon is 168°. Therefore, the number of sides will be,

[tex]168 = \dfrac{(n-2) \times 180^o}{n}[/tex]

168n = 180n - 360

180n - 168n = 360

12n  = 360

n = 30

Hence, The number of sides of the regular polygon each interior angle measuring 168° is 30.

Nora's calzone equation = option a, c - 3 = 9.49

Hope this helps

Answer:

the solution is the last one.

Step-by-step explanation:

We know that for a second grade equation of the type:

ax^2 + bx + c = 0

The solution will be given by the quadratic formula, which states that:

x1 = [-b + sqrt(b^2 - 4ac)]/2a

x2 = [-b - sqrt(b^2 - 4ac)]/2a

So, according to the solution, we have:

x1 = [-5 + 2sqrt(7)]/3

Then:

2a = 3

-b = 5

b^2 - 4ac = 28

Solving each equation:

a = 2/3

b= -5

c = 9/8

None of the alternatives equals the values obtained before. So we can say that the expression is simplified.

Now we knoe what the first and second equation are wrong because b is not equal to -5.

So we have the other two alternatives, where b=-10. This gives us an idea that maybe, the equation is simplified by two. If that's the case:

then:

2a = 6

b= -10

b^2 - 4ac = 112

Then b=-10, a = 3 and c=-1

So the solution is the last one.

Final answer:

The correct quadratic equation with the solutions x = 5 ± 2√7 / 3 is 3x² - 10x - 1 = 0, determined by matching the given solution to the quadratic formula.

Explanation:

The student is asking which of the given quadratic equations has the solutions x = 5 ± 2√7 / 3. The correct equation that yields these solutions must be in the form ax² + bx + c = 0, where a, b, and c are constants.

To determine the right equation, we can work backwards from the given solutions using the quadratic formula:

x = ∛( -b ± √(b² - 4ac) ) / 2a

Comparing the solutions to the standard form obtained by the quadratic formula, we need to match the coefficients such that:

After testing each equation, we find that:

The discriminant for the last equation is (10)² - 4×3×(-1) = 100 + 12 = 112, which is 4×7, confirming that x = 5 ± 2√7 / 3 are indeed the solutions.
