Find the area of a 120° sector of a circle whose radius is 6.

4 sq. units
12 sq. units
24 sq. units

Answer:

-3+4

Step-by-step explanation:

if it's put in parentheses it needs to be done first

For this case we must find the value of the variable "x" of the following expression:

[tex]2 (3x-1) \geq4x-6[/tex]

We apply distributive property to the terms within parentheses: [tex]6x-2 \geq4x-6[/tex]

We subtract 4x on both sides:

[tex]6x-4x-2 \geq-6\\2x-2 \geq-6[/tex]

We add 2 to both sides:

[tex]2x \geq-6 + 2\\2x \geq-4[/tex]

We divide between 2 on both sides:

[tex]x \geq \frac {-4} {2}\\x \geq-2[/tex]

Answer:

[tex]x \geq-2[/tex]

Answer: [tex]x\geq -2[/tex]

Step-by-step explanation:

Given the inequality [tex]2(3x - 1) \geq 4x -6[/tex] you need to solve for "x".

Apply Distributive property on the left side of the equation:

 [tex]6x - 2 \geq 4x -6[/tex]

Now add 2 to both sides:

 [tex]6x - 2+(2) \geq 4x -6+(2)[/tex]

 [tex]6x \geq 4x -4[/tex]

The next step is to subtrac [tex]4x[/tex] from both sides:

 [tex]6x-(4x) \geq 4x -4-(4x)[/tex]

 [tex]2x \geq -4[/tex]

And finally, divide both sides by 2:

[tex]\frac{2x}{2}\geq  \frac{-4}{2}\\\\x\geq -2[/tex]

A point is written as ( h, k) when a point is rotated 90 degrees about the origin the new point becomes (-k,h)

s is located at (5,4) where h = 5 and k = 4

The rotated point would be located at (-4,5 )

The distance traveled by a car and the amount of gas used are directly proportional. The more distance covered, the more gas is consumed. This relationship can be quantified to make estimates for a specific car's fuel needs over given distances.

The relationship between the distance traveled by a car and the amount of gas in the car is directly proportional, that is, the more distance the car travels, the more gas it consumes. This correlation can be quantified for a specific car and then used to estimate gas consumption for given distances based on the car's average speed.

For example, let's say that a 2014 Lamborghini Aventador Roadster travels from Philadelphia to Atlanta, covering a distance of about 1250 km, and uses 213 L of gasoline. This gives us a standard ratio of gas consumption against the distance. We could say that for every 1250 km traveled, the car would need about 213 L of gas. This is a simplified model as there are other variables at play such as traffic conditions, velocity, etc.

Gasoline powers the engine which provides the force needed to move and maintain the car's speed. As the path traced (distance) increases, more fuel is consumed. This relationship of distance traveled and fuel consumed can be defined as a directly proportional relationship.

Step-by-step explanation:

Answer:

Option 2) When the x-value is 0, the y-value is 1.

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Remember that in a direct variation

For x=0, the value of y is equal to zero too

therefore

The graph is not a direct variation , because

When the x-value is 0, the y-value is 1.

Answer:

If two chords intersect each other in a circle, then the product of the segments of one chord equals the product of the segments of the other chord.

x² = 12

x = 2√3

The formula x = r0 is used to calculate the length of a circular arc 'x', given the radius 'r' and an angle '0' in radians. For example, for a radius of 0.15m and an angle of 75.4 radians, we find x = 11m.

The problem revolves around the relationship between the radius r and an angle in radians 0, given by the formula x = r0. This applies to questions involving the measurement of a circular arc, where 'x' is the length of the arc. An example calculation would be, if we had a radius of 0.15m and an angle of 75.4 radians, we would multiply these to find 'x', giving us x = 11m. Similarly, for a radius of 0.0450m and an angle of 220 radians, x = 9.90m. Notice that the unit of 'x' will always be in the same unit as the radius (in this case, meters).

The function f(x) = 4.34 is a constant function, which means it does not change regardless of the value of 'x'. Thus, none of the options provided (A: Decreasing linear, B: Exponential growth, C: Increasing linear, D: Exponential decay) correctly describe the function.

The function represented by f(x) = 4.34 is a constant function.

This is because no matter what value of 'x' you put into the function, the output is always going to be 4.34.

Looking at the options provided:

A. Decreasing linear - This indicates that the function should decrease as 'x' increases, which is not the case here.

B. Exponential growth - This would mean the function increases at an increasing rate, which also does not apply to a constant value.

C. Increasing linear - This suggests that the function's value should increase as 'x' increases, which is not true for a constant function.

D. Exponential decay - This implies the function's values decrease at a decaying rate, which, again, does not match a constant value.

Therefore, none of the options accurately describe f(x) = 4.34.

The function is neither increasing nor decreasing and it is not an exponential function.

2. C

Step-by-step explanation:

H in the parent function equations are always negative and k is always positive.

Ex:

[tex]f(x)=2^(x-h)+k[/tex]

So that means when we're adding 4 to the exponent, we're actually subtracting, therefore moving the graph 4 units to the left.

Then, since k is positive, and we're adding 8, we move the graph 8 units up.

Answer:

11-3i-4-5i

=11-4-3i-5i

=7-8i

Follow below steps:

The difference of the complex numbers (11-3i) and (4+5i) is computed by subtracting the real and imaginary parts separately. The real parts are 11 and 4, and their difference is 11 - 4 = 7. The imaginary parts are -3i and +5i, and their difference is -3i - 5i = -8i. Therefore, the difference of the two complex numbers is 7 - 8i.

Step-by-step explanation:

Answer:

x = 5/2

Step-by-step explanation:

log4(x^2+5x)-log8(x^3)=1/log3(4)

log(x^2 + 5 x) / log(4) - log(x^3) / log(8) = log(3) / log(4)

log(x (x+5))/log(4) - log(x^3) / log(8) = log(3) / log(4)

(3 log(x (x+5)) - 2 log(x^3)) / log(64) = log(3) / log(4)

3 log(x (x+5)) - 2 log(x^3) = 3 log(3)

log((3 x)/(x+5))=0

x=5/2

Answer:

5/2

Step-by-step explanation:

So first of all 1/log_3(4) can be written as log_4(3)...

So everything is base 4 except the log_8(x^3)...

We can play with this to get it so that the base is 4.

Let y=log_8(x^3) then 8^y=x^3

Rewrite 8 as 4^(3/2) so we have

4^(3/2 *y)=x^3

Now rewriting in log form gives: log_4(x^3)=3/2*y

Then solving that for y gives 2/3*log_4(x^3) or log_4(x^2)... let's put it back into the equation:

log_4(x^2+5x)-log_4(x^2)=log_4(3)

log_4((x^2+5x)/x^2)=log_4(3)

Set insides equal:

(x^2+5x)/x^2=3

Cross multiply:

x^2+5x=3x^2

Subtract 3x^2 on both sides:

-2x^2+5x=0

Factor

-x(2x-5)=0

So solutions are 0 and 5/2.  

We have to verify these...

0 isn't going to work because we can't do log of 0

it makes x^2+5x 0 and x^3 0

The only solution is 5/2.

The standard equation of a circle is in the form:

(x-a)^2 + (y-b)^2 = r^2

where; a is the x coordinate of the center, b is the y coordinate of the center, and r is the radius of the center.

In this case, a is -5, b is 2, and r is 7.

Therefore, the equation of this circle would be

(x+5)^2 + (y-2)^2 = 49

Answer:

Second option: [tex](x +5)^2 + (y -2)^2 =49[/tex]

Step-by-step explanation:

The center-radius form of the circle equation is:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where "r" is the radius and the center is at the point [tex](h,k)[/tex]

Since the center of this circle is at the point [tex](-5, 2)[/tex], we can identify that:

[tex]h=-5\\k=2[/tex]

We know that the radius is 7, then:

[tex]r=7[/tex]

Now we must substitute these values into the equation  [tex](x - h)^2 + (y - k)^2 = r^2[/tex] to find the equation of this circle.

This is:

 [tex](x - (-5))^2 + (y - 2)^2 = (7)^2[/tex]

 [tex](x +5)^2 + (y -2)^2 =49[/tex]

Answer:

m=p*V

Step-by-step explanation:

we have

p=m/V

Solve for m

That means-----> isolate the variable m

Multiply both sides by V

p*V=(m/V)*V

Simplify

p*V=m

rewrite

m=p*V

Answer:

[tex]m=\rho*V[/tex]

Step-by-step explanation:

Note that the formula for density depends on two variables

The mass m

The volume V

[tex]\rho=\frac{m}{V}[/tex]

If we have the density [tex]\rho[/tex] and the volume V and we want to find the mass m then we solve the equation for the variable m

[tex]\rho=\frac{m}{V}[/tex]

Multiply both sides of the equality by the volume V

[tex]\frac{m}{V}*V=\rho*V[/tex]

[tex]m=\rho*V[/tex]

The formula is:

[tex]m=\rho*V[/tex]

[tex]\left(\dfrac{f}{g}\right)(x)=\dfrac{3x+2}{3x-5}[/tex]

Answer:

[tex](\dfrac{f}{g})(x)=\dfrac{3x+2}{3x-5}[/tex] for [tex]x\neq \dfrac{5}{3}[/tex].

Step-by-step explanation:

The given functions are

[tex]f(x)=3x+2[/tex]

[tex]g(x)=3x-5[/tex]

We need to find the function [tex](\dfrac{f}{g})(x)[/tex].

Using division property of functions.

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

Substitute the values of functions.

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

This function is defined for all values of x, except a value for which 3x-5=0.

[tex]3x-5=0\Rightarrow x=\dfrac{5}{3}[/tex]

Therefore, the required function is [tex](\dfrac{f}{g})(x)=\dfrac{3x+2}{3x-5}[/tex] for [tex]x\neq \dfrac{5}{3}[/tex].

Answer:

One Solution

(2, 1)

Step-by-step explanation:

We have the following system of equations

[tex]x+4y = 6\\y=2x-3[/tex]

To solve the system, substitute the second equation in the first equation and solve for the variable x

[tex]x+4(2x-3) = 6[/tex]

[tex]x+8x-12 = 6[/tex]

[tex]9x = 6+12[/tex]

[tex]9x = 18[/tex]

[tex]x = \frac{18}{9}[/tex]

[tex]x = 2[/tex]

Now substitute the value of x into any of the two equations and solve for the variable y.

[tex]y=2(2)-3[/tex]

[tex]y=4-3[/tex]

[tex]y=1[/tex]

Finally the system of equations has one solution

(2, 1)

Answer:

D

Step-by-step explanation:

Using the rules of exponents

• [tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]

• [tex]a^{\frac{1}{2} }[/tex] ⇔ [tex]\sqrt{a}[/tex]

Hence

[tex]36^{-\frac{1}{2} }[/tex] = [tex]\frac{1}{36^{\frac{1}{2} } }[/tex] = [tex]\frac{1}{\sqrt{36} }[/tex] = [tex]\frac{1}{6}[/tex]

For this case we must find an expression equivalent to:

[tex]36 ^ {- \frac {1} {2}}[/tex]

By definition of power properties we have to:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

So, rewriting the expression we have:

[tex]\frac {1} {36 ^ {\frac {1} {2}}}=[/tex]

By definition of power properties we have to:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So:

[tex]\frac {1} {\sqrt {36}} =\\\frac {1} {\sqrt {6 ^ 2}} =\\\frac {1} {6}[/tex]

Answer:

54 cm^2

Step-by-step explanation:

The area of a right triangle is the easiest triangle for which you can find the area.

The area of any triangle is Base * height / 2

The base and height of a right triangle are always the two sides that are not the hypotenuse. In this case

base = 9

height = 12

Area = 9 * 12/2

Area = 54 square cm.

Answer: A

Answer:

12/5

Step-by-step explanation:

tan(F)    =opposite side to angle F  over (Fraction Bar) adjacent side to angle F

[tex] \tan(F)=\frac{\text{ opposite side to angle F } }{ \text{ adjacent side to angle F} } [/tex]

The side that is opposite is the side that doesn't include F.

The side the is adjacent will include F (this is not the hypotenuse which is opposite the 90 degree angle).

So

[tex]\tan(F)=\frac{12}{5}[/tex]
