The statement which is true about the minimum values of the two quadratic functions presented in the question is f(x) and g(x) have the same minimum value. Therefore, the correct option is option C.

When  [tex]tan(\theta) = 1[/tex] , the value of  [tex]sin(\theta)[/tex] in quadrant III is [tex]\frac{-1}{\sqrt{2} }[/tex]. Therefore the correct option is option B.

First picture

Finding the vertex of each function, to determine the minimum values of functions. The vertex of a quadratic function in the form [tex]f(x) = ax^{2} +bx + c[/tex] can be find by the coordinates [tex](\frac{-b}{\ 2a} , f(\frac{-b}{\ 2a} ))[/tex].

For function [tex]f(x) = x^{2} +4x - 4[/tex], a = 1, b = 4. Substituting these values in vertex formula,

[tex]x = \frac{-b}{\ 2a} = \frac{-4}{\ (2\ *\ 1)} = -2[/tex]

Finding the value of f(-2):

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

= 4 - 8 - 4

= -8

So the vertex of f(x) is (-2, -8), and the minimum value is -8.

For function g(x)

From the values, the minimum value of g(x) is -8, which occurs when x = 0.

Comparing the minimum values of f(x) and g(x),

Minimum value of f(x) is -8

Minimum value of g(x) is -8

Therefore, the correct answer is: C. f(x) and g(x) have the same minimum value.

Second picture

In Quadrant III, x-coordinate and y-coordinate both are negative.

[tex]tan(\theta) = \frac{sin(\theta)}{cos(\theta)} = 1[/tex]

Since, [tex]cos(\theta)[/tex] is negative and [tex]tan(\theta) = 1[/tex], using the Pythagorean identity to find [tex]cos(\theta)[/tex],

[tex]cos^2(\theta) = \frac{1 }{(1 + tan^2(\theta))}[/tex]

[tex]cos^2(\theta) = \frac{1}{(1 + 1)}[/tex]

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

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

[tex]cos(theta) = -\frac{\ 1}{\sqrt{2} }[/tex]

⇒ [tex]sin(\theta) = tan(\theta) * cos(\theta)[/tex]

[tex]sin(\theta) = 1 * (-\frac{1}{\sqrt{2} } )[/tex]

[tex]sin(\theta) = -\frac{\ 1}{\sqrt{2} }[/tex]

Therefore, in Quadrant III, [tex]sin(\theta) = -\frac{\ 1}{\sqrt{2} }[/tex]

Answer:

x=140

Step-by-step explanation:

The equation to calculate what divided by 5 equals 28 is as follows:

X/5 = 28

Where X is the answer. When we solve the equation by multiplying each side by 5, you get get:

X = 140

The exponential equation that models the situation is; y = 2,716·(0.85)ˣ

The amount of battery charge that will be in the phone after 6 hours therefore is 1024 milliamperes

An exponential equation is an equation that has the input variable as an exponent; y = a·bˣ

The rate at which the cell phone battery is losing battery charge = 15% per hour

The capacity of the iPhone X starts at 2,716 milliamperes

Therefore, the rate at which at which the battery is discharging is an exponential relationship. The equation that models the situation can therefore be expressed as follows;

y = 2,716 × (1 - 0.15)ˣ = 2,716 × (0.85)ˣ

Where;

y = The current battery charge

x = The number of hours the battery has been losing battery charge

When x = 6, we get;

y = 2,716 × (0.85)⁶ ≈ 1024

y = 1024

Answer: the top left and top right are similar

Step-by-step explanation:

Similar means the sides are proportional meaning you multiplied the small one by the same number to get a shape that is "similar" (same angles, same shape just bigger or smaller.

So the first one, you multiply both sides by 2  (3x2) and (5x2) = 6x10 so yes similar

the second one isn't same shape so it is not similar

the third one doesn't have the same angles so it's not the same shape

the fourth one is not multiplied by same number to be increased

the fifth one is similar because it's the same shape but 3 times bigger

the bottom shape is the same exact shape but just flipped so it is congruent not similar

Answer:

Pythagorean identity: sin²Ф + cos²Ф = 1

Step-by-step explanation:

The sine, cosine, and tangent values of an angle in a right-angled triangle are related by the Pythagorean identity, a fundamental trigonometric identity: sin²Ф + cos²Ф = 1

Given: cos(a) = 0.4 (we can use this to identify sin(a) ),

sin²(a) + (0.4)² = 1

sin²(a) = 1 - (0.4)²

sin²(a) = 1 - 0.16

sin²(a) = 0.84

Taking sq. roots on both sides will give,

sin(a) = ±√0.84

Sine is positive in the first and second quadrants, which leads us to the following conclusion:

Answer: P*0.06*(50/360) = 11900

Step-by-step explanation: good luck

Answer:

  1428000

Step-by-step explanation:

You want the principal that would result in interest of 11900 at a rate of 6% for a period of 50 days.

Ordinary interest is calculated on the basis of 360 days per year. The fraction of a year represented by 50 days is 50/360, so the interest formula tells us ...

  I = Prt . . . . . . . where P is the principal at rate r for t years

  11900 = P·0.06·(50/360)

  P = 11900/(0.06·50/360) = 1428000

The principal amount is 1428000.

To find the missing values, we can use the ROI formula:

ROI = Margin x Turnover

We are given that ROI is 70%. We can use this to solve for the missing values:

Margin x Turnover = 70%

We can rearrange this equation to solve for Margin:

Margin = ROI / Turnover

To find Turnover, we can use the formula:

Turnover = Sales / Average Operating Assets

Plugging in the given values, we get:

Turnover = $300,000 / $187,500 = 1.6

This gives you the critical numbers then you have to evaluate at all points:

[tex]f(4) = 464 \\f(5) = 475\\f(8) = 448\\f(9) = 459[/tex]

Showing the minimum is f(4) and the maximum is f(5)

The simplified answers are:

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

[tex]g(f(x)) = 6x + 9[/tex]

A function is a rule that assigns a unique output value to each input value. It is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. The input values are often referred to as the domain of the function, while the output values are referred to as the range.

To find f(g(x)), we first need to evaluate g(x) and then use the result as the input for f(x). So:

[tex]f(g(x)) = f(2x - 1)[/tex](substituting [tex]g(x) = 2x - 1)[/tex]

[tex]= 3(2x - 1) + 5[/tex](substituting[tex]f(x) = 3x + 5)[/tex]

To find g(f(x)), we follow a similar procedure:

Answer:

To find the interest earned by Wayne, we can use the simple interest formula:

I = P * r * t

Where:

I = interest earned

P = principal amount

r = interest rate per year

t = time period in years

In this case, we know that:

P = 4000 (the principal amount)

r is unknown (we'll come back to this)

t = 8 years (the time period)

We also know that the interest earned is 4.6, so we can substitute these values into the formula and solve for r:

4.6 = 4000 * r * 8

r = 4.6 / (4000 * 8) = 0.00014375

Now that we know the interest rate per year, we can use the simple interest formula to find the total interest earned by Wayne:

I = P * r * t = 4000 * 0.00014375 * 8 = 4.6

So Wayne earned 4.6 in interest over 8 years.

To find the total amount on the account, we can simply add the interest to the principal:

Total amount = Principal + Interest = 4000 + 4.6 = 4004.6

So the total amount on the account after 8 years is 4004.6.

Answer: The total amount on Wayne's account after 8 years is $5,472.

Step-by-step explanation:

To calculate the interest earned by Wayne, we can use the formula:

I = P * r * t

Where I is the interest, P is the principal amount, r is the interest rate, and t is the time in years.

In this case, Wayne earns 4.6% simple interest for 8 years on 4000. So, P = 4000, r = 0.046 (since 4.6% is equivalent to 0.046), and t = 8.

I = 4000 * 0.046 * 8

I = 1472

Therefore, Wayne earns $1,472 in interest.

To calculate the total amount on the account, we can add the interest to the principal:

Total amount = Principal + Interest

Total amount = 4000 + 1472

Total amount = $5,472

Therefore, the total amount on Wayne's account after 8 years is $5,472.

Therefore:

[tex]\tan \theta + \dfrac{1}{\tan \theta}=\dfrac{\sin \theta}{\cos \theta}+\dfrac{\cos \theta}{\sin \theta}[/tex]

Add the fractions on the right side of the equation:

Apply the identity sin²θ + cos²θ = 1:

[tex]\begin{aligned}\tan \theta + \dfrac{1}{\tan \theta}&=\dfrac{\sin \theta}{\cos \theta}+\dfrac{\cos \theta}{\sin \theta}\\\\ &=\dfrac{\sin \theta \cdot \sin \theta}{\cos \theta \cdot \sin \theta}+\dfrac{\cos \theta \cdot \cos \theta}{\sin \theta \cdot \cos \theta}\\\\ &=\dfrac{\sin^2 \theta }{\sin \theta \cos \theta}+\dfrac{\cos^2 \theta }{\sin \theta \cos \theta}\\\\&=\dfrac{\sin^2 \theta + \cos^2\theta}{\sin \theta \cos\theta}\\\\&=\dfrac{1}{\sin \theta \cos\theta}\end{aligned}[/tex]
