Answer:

[tex]\boxed{\tan \theta}[/tex]

Step-by-step explanation:

[tex]\dfrac{\tan \theta }{\sin^{2} \theta + \cos^{2} \theta}[/tex]

Use the trigonometric identity

[tex]\sin^{2}\theta + \cos^{2}\theta = 1[/tex]

Then,

[tex]\dfrac{\tan \theta }{\sin^{2} \theta + \cos^{2} \theta} = \dfrac{\tan \theta }{1} = \boxed{\tan \theta}[/tex]

The correct option is d. tan θ. The simplified expression is [tex]\(\tan\ \theta\)[/tex].

The expression you provided is:

[tex]\[ \frac{\tan\ \theta}{\sin^2 \theta + \cos^2 \theta} \][/tex]

We know that [tex]\(\sin^2 \theta + \cos^2 \theta = 1\)[/tex] due to the Pythagorean identity for sine and cosine.

So, the expression simplifies to:

[tex]\[ \frac{\tan\ \theta}{1} = \tan\ \theta \][/tex]

Therefore, the correct simplified expression is [tex]\(\tan\ \theta\)[/tex].

The complete question is:

Final answer:

To find the 2010 cost of filling a gas tank based on 1970 prices, divide the 1970 total cost by the price per gallon to find the number of gallons, then multiply that by the 2010 price per gallon. The cost to fill the same tank in 2010 would be $47.34.

Explanation:

The question is asking to calculate the cost of a full tank of gas in 2010 based on the cost from 1970. To find out how much it would cost in 2010, we need to first determine the number of gallons that could be bought for $6 in 1970 at $0.36 per gallon. This can be calculated by dividing $6 by $0.36, which equals 16.67 gallons (approximately). Now, assuming the tank size has not changed, to find out the cost in 2010, we multiply the number of gallons by the 2010 price per gallon. Thus, 16.67 gallons multiplied by $2.84 per gallon equals $47.34.

Final answer:

The zeros of f(x) = x^3 - 4x^2 - 5x + 20 are 4 and (-1 +/- sqrt(21)) / 2.

Explanation:

The given function is f(x) = x^3 - 4x^2 - 5x + 20. To find the zeros of the function, we need to solve the equation f(x) = 0. One way to find the zeros is by using synthetic division or polynomial long division. However, in this case, we can use factoring by grouping to simplify the equation:

f(x) = (x^3 - 5x) + (-4x^2 + 20)

f(x) = x(x^2 - 5) + (-4)(x^2 - 5)

f(x) = (x - 4)(x^2 + x - 5)

Setting each factor equal to zero, we have:

x - 4 = 0  ---> x = 4

x^2 + x - 5 = 0

Using the quadratic formula, we can find the solutions of the quadratic equation:

x = (-b +/- sqrt(b^2 - 4ac)) / (2a)

Plugging in the values a = 1, b = 1, and c = -5, we get:

x = (-1 +/- sqrt(1^2 - 4(1)(-5))) / (2(1))

x = (-1 +/- sqrt(1 + 20)) / 2

x = (-1 +/- sqrt(21)) / 2

So, the zeros of f(x) = x^3 - 4x^2 - 5x + 20 are x = 4 and x = (-1 +/- sqrt(21)) / 2.

Answer:

The diameter of a circle with an area of 804.25 cm is 32 cm

Step-by-step explanation:

We know that formula for area of circle is:

Area of Circle = πr^2

804.25 =  3.14 * r^2

=> r^2 = 804.25 / 3.14

r^2 = 256.13

Taking square root on both sides

√r^2 = √256.13

r = 16.0

and r is half of diameter i.e

r = diameter / 2

=> diameter = 2r

so, diameter = 2 * 16

diameter = 32 cm

So, the diameter of a circle with an area of 804.25 cm is 32 cm.

The diameter is approximately [tex]\(32.02\)[/tex] cm, calculated from [tex]\(d = 2 \times 16.01\)[/tex], where [tex]\(r \approx 16.01\)[/tex] cm.

To find the diameter of a circle with an area of 804.25 cm², follow these steps:

Step 1:

Recall the formula for the area [tex](\(A\))[/tex] of a circle: [tex]\(A = \pi r^2\)[/tex], where r is the radius of the circle.

Step 2:

We're given the area [tex]\(A = 804.25\)[/tex] cm². Rearrange the formula to solve for [tex]\(r\)[/tex]: [tex]\(r = \sqrt{\frac{A}{\pi}}\)[/tex].

Step 3:

Substitute the given area into the equation: [tex]\(r = \sqrt{\frac{804.25}{\pi}}\).[/tex]

Step 4:

Calculate the radius: [tex]\(r[/tex] ≈ [tex]\sqrt{\frac{804.25}{\pi}}[/tex] ≈ [tex]\sqrt{256.25}[/tex] ≈ 16.01 cm.

Step 5:

Recall that the diameter [tex](\(d\))[/tex] of a circle is twice the radius: [tex]\(d = 2r\)[/tex].

Step 6:

Substitute the calculated radius into the equation: [tex]\(d = 2 \times 16.01\)[/tex].

Step 7:

Calculate the diameter: [tex]\(d[/tex] ≈ [tex]2 \times 16.01[/tex] ≈ [tex]32.02\)[/tex] cm.

Therefore, the diameter of the circle with an area of 804.25 cm² is approximately 32.02 cm.

Answer:

C)-2(9+32n)

Step-by-step explanation:

The given expresion is

[tex] - 18 - 64n[/tex]

We can rewrite this expression as:

[tex] - 2 \times 9 + - 2 \times 32n[/tex]

We factor -2 to obtain:

[tex] - 2(9 + 32n)[/tex]

Note that, we can use the distributive property to obtain:

[tex] - 2(9 + 32n) = - 18 - 64n[/tex]

Therefore the correct answer is C)-2(9+32n)

The expression equivalent to (-18)-64n is option A: -2(9-32n). This is because when you distribute the -2 across the terms in the parentheses, it gives you the original expression.

To find which expression is equivalent to (-18)-64n, we can factor out the greatest common factor (GCF) from each term. The GCF of -18 and -64n is -2. Thus, when we factor out -2, we are left with:

(-18)-64n = -2(9 + 32n).

But we have to pay attention to our signs; we should distribute -2 within the parentheses to check our result:

-2 × 9 = -18

-2 × 32n = -64n

Thus, option A -2(9-32n) is the correct equivalent expression, as the negative sign in front of the parentheses will switch the signs of the terms inside when distributed. Options B, C, and D either lack the necessary negative sign or have the incorrect sign for 32n.

Answer:

option B

option D

Step-by-step explanation:

1)

First we will remove radical sign as[tex]\sqrt[n]{x}=x^{\frac{1}{n} }[/tex] and then multiply the powers.

2)

The "power rule" tells us that to raise a power to a power, just multiply the exponents.

Answer:

70.58 ft²

Step-by-step explanation:

One pie-shaped sub-area of this octagon has two sides of length 5 ft and a central angle of 360°/8, or 45°.  We need to find the area of one such sub-area and then multiply the result by 8 to find the total area of the octagon.

Picture this pie-shape, this isosceles triangle with two sides of length 5 ft and central angle 45°.  Half of that angle is 22.5°.  Half of the base of this triangle is 5 sin 22.5°, or 1.91; the full base length is twice that, or 3.82.  the height of the triangle is 5 cos 22.5°, or 4.62.

The formula for the area of a triangle is

A = (1/2)(base)(height), which in this case is:

A = (1/2)(3.82 ft)(4.62 ft) = 8.82 ft²

and so the area of the whole octagon is 8(8.82 ft²), or 70.58 ft²

Step-by-step explanation:

The percentage of followers are actually real = 11%

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

the number of real followers = 120

the number of fake followers purchased = 1000

So, the total number of followers are

= 1000 + 120

= 1120

Now, we find the percentage of followers that are actually real.

= (120/1120) × 100

= 0.1071 × 100

= 10.71%

≈ 11%

Therefore, the percentage of followers are actually real = 11%
