Answer:

x > -1

Step-by-step explanation:

Simplify x – 3 > -4 by adding 3 to both sides:

x > -1

This matches the 2nd answer choice.

The solution of the given expression x - 3 > -4 will be x > -1 thus, option (A) is correct.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given,

x - 3 > -4

Add 3 on both sides of the above inequality,

x - 3 + 3 > -4 + 3

x > -1

Hence "The solution of the given expression x - 3 > -4 will be x > -1".

Answer:

39 feet

Step-by-step explanation:

From the question;

let length of ladder =x feet

height of ladder will be=x-3 feet

ground distance of ladder bottom to building=15 feet

Applying Pythagorean relation

a²+b²=c²

where a=15 feet b=x-3 feet and c=x feet thus

x²-15²=(x-3)²

x²-225=x²-6x+9

collect like term

x²-x²-225-9=-6x

-234= -6x

x= 39 feet length of ladder

distance from ground to top of ladder= 39-3=36 feet

The length of the ladder is 39 feet.

Let's denote the length of the ladder as x. According to the problem, the distance from the ground to the top of the ladder is 3 feetless than the length of the ladder. So, the height from the ground to the top of the ladder is x - 3 feet. The distance from the bottom of the ladder to the building is given as 15 feet. We can set up a right triangle where the ladder is the hypotenuse and solve for x using the Pythagorean Theorem:

x^2 = (x - 3)^2 + 15^2

Expanding and simplifying, we get:

x^2 = x^2 - 6x + 9 + 225

Combining like terms, we have:

0 = -6x + 234

Now, let's solve for x:

6x = 234

x = 39

Therefore, the length of the ladder is 39 feet.

Answer:

x=  nπ/3

Step-by-step explanation:

We are given that: [tex]\sqrt{3}*tan(3x) = 0[/tex]

Divide both sides by [tex]\sqrt{3}[/tex]

=> [tex]\frac{\sqrt{3}*tan(3x)}{\sqrt{3}} = \frac{0}{\sqrt{3}}[/tex]

=> tan(3x) = 0

we know that arctan(0) = nπ

Therefore,

3x = nπ

or

x=  nπ/3 (where n belongs to positive and negative integers)

Trig ratios can only be used on right triangles with acute measures.

If given an angle and there are adjacent and opposite sides, then use tan(opposite/adjacent)

If given an angle and there is an adjacent side and a hypotenuse, then use cosine(adjacent/hypotenuse)

If given an angle and there is an opposite and adjacent side, then use sin(opposite/hypotenuse)

A common mnemonic device used to memorize the trig rules is SOH-CAH-TOA

Trig ratios refer to the ratios of sides of a right triangle expressed about an angle. These include sine (sin), cosine (cos), and tangent (tan), as well as their reciprocals cosecant (csc), secant (sec), and cotangent (cot). They are fundamental in many real-world applications, including engineering, navigation, and physics.

The trigonometric ratios are ratios of sides of a right triangle. Specifically, we have the following respected relations between angles and sides: Sine (sin) is the ratio of the length of the side opposite the angle to the length of the hypotenuse. Cosine (cos) is the ratio of the length of the adjacent side to the length of the hypotenuse. Tangent (tan) is the ratio of the opposite side's length to the adjacent side's length. This is also equivalent to sin/cos. Respective reciprocal ratios are: cosecant (csc), secant (sec), and cotangent (cot).

These trig ratios allow us to determine distances, angles, and other aspects within a right triangle or representation of a circle.

For example, suppose we have a right triangle where the angle A is 30°, and the hypotenuse (the side opposite the right angle) is 10. In that case, we can determine the length of the opposite side by using the sin ratio, which is sin(30°) = Opposite/Hypotenuse. Solving, we get Opposite = sin(30°) * 10.

How do these trig ratios apply to real-world examples? Consider a ladder leaning against a wall, creating a right triangle with the ground. With the angle made at the ground and the length of the ladder, we can figure out how high up the ladder reaches on the wall using sin or how far from the base of the ladder's base should be placed using cos.

In conclusion, understanding trig ratios is an essential part of trigonometry and has numerous practical applications in real life, from construction and engineering to navigation and physics.

Answer: (-6, 4)

Step-by-step explanation:

You can use the Elimination method:

- Multiply the the first equation by -3 and the second one by 5.

- Add both equations.

- Solve for y:

[tex]\left \{ {{(-3)(5x+4y=-14(-3)} \atop {5(3x+6y)=6(5)}} \right.\\\\\left \{ {{-15x-12y=42} \atop {15x+30y=30}} \right.\\-------\\18y=72\\y=4[/tex]

- Susbtittute y=4 into any of the original equations and solve for x:

[tex]3x+6(4)=6\\3x=6-24\\3x=-18\\x=-6[/tex]

Then the ordered pair is:

(-6, 4)

Answer:

(-6, 4)

Step-by-step explanation:

We are given the following two equations and we are to solve them:

[tex]5x+4y=-14[/tex] --- (1)

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

Using the substitution method:

From equation (2):

[tex] 3 x = 6 - 6 y \\\\ x = \frac { 6 - 6 y } { 3 } \\ \\ x = 2 - 2 y [/tex]

Substituting this value of x in equation (1) to get:

[tex] 5 ( 2 - 2 y ) + 4 y = -14 \\\\ 10 - 10 y + 4 y = -14 \\\\ 1 0 + 14 = 6 y \\\\ y = \frac { 24 } { 6 } \\ \\ y = 4 [/tex]

Putting this value of y in equation (2) to find the value of x:

[tex] 3 x + 6 ( 4 ) = 6 \\\\ 3x + 24 = 6 \\\\ 3x = 6 - 24 \\\\ x = \frac { -18 } { 3 } \\\\ x = -6 [/tex]

Therefore, (-6, 4) is the solution to the given system of equations.

The width of the prism is approximately 2.2 feet.

Let's assume that the width of the prism is x feet. Since the length of the prism is four times the width, the length can be represented as 4x feet. Given that the height is 8 feet, we can use the formula for the volume of a rectangular prism: Volume = Length x Width x Height. Plugging in the given values, we get the equation 160 = 4x * x * 8. By solving this equation, we find that the width of the prism is approximately 2.2 feet (when rounded to the nearest tenth).

Answer:

The correct answer option is a) y =2.

Step-by-step explanation:

We are given the following equation and we are to find the solution of this equation:

[tex] | 1 0 - 5 y | = 2 0 [/tex]

Here, the expression [tex]10-5y[/tex] is given in a modulus, which means that its value cannot be negative.

[tex] 1 0 - 5 y = 2 0 [/tex]

[tex] -5 y = 2 0 - 1 0 [/tex]

[tex] -5 y = 1 0 [/tex]

Ignoring the negative sign because of mod.

[tex]y=\frac{10}{5}[/tex]

y = 2

The equation |10-5y| = 20 has two solutions, which are y = -2 and y = 6. These solutions are obtained by considering the two possible scenarios due to the absolute value.

The equation provided is |10-5y| = 20. To solve the equation, we need to consider the absolute value conditions separately. Since absolute value represents distance, it can be equal to the positive or negative of the number within the absolute value. Therefore, we have two cases to solve:

10 - 5y = 20

10 - 5y = -20

Solving the first case:

-5y = 20 - 10
-5y = 10
y = -2

Solving the second case:

-5y = -30
y = 6

Thus, the solutions to the equation are y = -2 and y = 6.

Answer:

amplitude:  3; midline is y = 2

Step-by-step explanation:

Note that the range of this function is [-1, 5], values that are 6 units apart.  The amplitude is half that, or 3 units.

The midline is the horiz. line halfway between -1 and +5.:  y = 3.

These values correspond to the last (fourth) answer choice.

The amplitude and midline of a periodic function can be determined from the function's equation. The amplitude is the absolute value of the coefficient attached to the sine or cosine, and the midline (or vertical shift) is the constant added or subtracted in the function.

From the equation of a periodic function, we can determine the amplitude and midline. The amplitude is the absolute value of the coefficient of the function while the midline (or the vertical shift) can be found as the constant added or subtracted in the equation.

Let's consider your periodic function as y = A sin(kx) + D. Here, |A| is the amplitude and D is the midline of the function. However, the function itself is not provided in your question.

For instance, in the function y=0.2 m sin(6.28 m¯¹x − 1.57 s¯¹t), the amplitude, wave number, and angular frequency can be read directly. The amplitude here is 0.2 m (the multiplier of the sine term). It and doesn't seem to be any shifts up or down, so the midline is y = 0 (the x-axis).

So, you can find the amplitude and midline of a periodic function from the equation itself, however, you need the specific equation of your function to do that.

Answer:

[tex]y = x^2 + 6x + 8[/tex]

Step-by-step explanation:

The equation can be written using information from the graph. The vertex of the parabola is (-3,-1). Use the vertex form [tex]y = a(x-h)^2 + k[/tex] by substituting h = -3 and k = -1. The equation becomes [tex]y = a(x--3)^2 + -1[/tex]. It simplifies to [tex]y = a(x+3)^2 - 1[/tex]. To find a, substitute the point (x,y) on the graph into the equation and solve for a. Substitute x = -2 and y = 0.

[tex]0 = a(-2+3)^2 - 1[/tex]

[tex]0 = a(1)^2 - 1[/tex]

[tex]0 = a - 1[/tex]
