Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

3x - y = 4 ( subtract 3x from both sides )

- y = - 3x + 4 ( multiply through by - 1 )

y = 3x - 4 → A

Answer:

x=0

Step-by-step explanation:

We can first add 49 to both sides to get (x+7)^2=49

We can then take the square root of both sides and get x+7=7

Subtract 7 to both sides and you get x=0

Answer:

\(x=-14\text{ and } x=0\)

Step-by-step explanation:

We are given:

\((x+7)^2-49=0\)

And we want to solve for x.

First, we can add 49 to both sides:

\((x+7)^2=49\)

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

\(x+7=\pm\sqrt{49}\)

Evaluate:

\(x+7=\pm7\)

Subtract 7 from both sides:

\(x=-7\pm7\)

So, we have two solutions:

\(x=-7+7\text{ and } x=-7-7\)

Evaluate:

\(x=0\text{ and } x=-14\)

So, from least to greatest, our solutions are:

\(x=-14\text{ and } x=0\)

A. The rate at which the elevation is changing is 1.5 feet/sec

B. The number of additional seconds to reach 50ft is 43.5sec

C. The number of second before her team requested for updates at the surface of water is 75sec

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. This is not a ratio of two like units, such as shirts. This is a ratio of two unlike units: cents and ounces.

rate of changing elevation = 21-15/4 = 6/4 = 1.5feet/sec

to reach 50 feet, the number sec = (50 -21)1.5= 29 ×1.5 = 43.5sec.

It was 75 seconds before her team requested an update at the surface of the water. I e 50 × 1.5 = 75sec

Answer:

Step-by-step explanation:

1) First find the y-intercept point

You can find it easily by finding the number without the variable. In this case, it is -1. With this draw a point on the y-axis line down to -1.

2) Find the slope.

Next, you can find a point by substituting a number for x. So in this example, I will be subbing x for 1.

y = -3(1) - 1

y= -3 - 1

y= -4

So there will be a point at (1,-4).

3) Graphing.

After you find that you can easily draw a straight line through both points.

By using the concept of combinations, we have determined that there are 210 three-digit numbers that can be formed using the digits 0-6 without repeating any of them. Among them, there are 90 odd numbers and 120 numbers greater than 330.

Combinations are a fundamental concept in mathematics, particularly in the field of combinatorics, which deals with counting and arranging objects.

To solve this problem, we can use the concept of combinations, which is a way of counting the number of ways we can choose k items from a set of n items. In this case, we want to find the number of three-digit numbers we can form from the set {0, 1, 2, 3, 4, 5, 6}, without repeating any of the digits.

First, we can determine the number of ways we can choose the first digit. Since there are seven digits to choose from, we have 7 options for the first digit.

Next, we can determine the number of ways we can choose the second digit. Since we have already used one of the digits, we only have 6 options left for the second digit.

Finally, we can determine the number of ways we can choose the third digit. Since we have used two of the digits, we only have 5 options left for the third digit.

Therefore, the total number of three-digit numbers we can form is given by the product of the number of choices for each digit:

7 x 6 x 5 = 210

So there are 210 different three-digit numbers that can be formed using the digits 0, 1, 2, 3, 4, 5, and 6, without repeating any of the digits.

To find the number of odd numbers, we need to consider that the last digit must be either 1, 3, or 5, since these are the only odd digits in the set. We can choose the first two digits in the same way as before, and then choose one of the three odd digits for the last digit. Therefore, the number of odd three-digit numbers is:

6 x 5 x 3 = 90

To find the number of three-digit numbers greater than 330, we need to consider that the first digit must be either 3, 4, 5, or 6. We can choose the first digit in 4 ways, and then choose the remaining two digits as before. Therefore, the number of three-digit numbers greater than 330 is:

4 x 6 x 5 = 120

Answer:

2.9

Step-by-step explanation:

11.6 divided by 4 equals 2.9

Answer:

2.9 :)

Step-by-step explanation:

The coordinates of such remaining pairs are (-1, 3), (4, 3), and (-1, -7), respectively (4, -7) There isn't a third pair. The edges of such a square are its vertices.

The positions of both the remaining pairings were (-1, 3), (4, 3), and (-1, -7), respectively (4, -7)

The criteria are as follows:

\(E= (-1,-2)\)

\(F = (4, -2)\)

Measure the distance EF.

\(EF = \sqrt{(x_{1} -x_{2}) ^{2} +(y_{1} -y_{2})^{2}\)

We do indeed have:

\(EF= \sqrt{(-1-4)^{2} }(-2--2)^{2}\)

\(EF= \sqrt{25}\)

EF= 5

E and F's y-coordinates will gain 5 in total.

\(C = (-1, -2 +5)\)

\(C= (-1,3)\)

\(D = (4 -2 +5)\)

\(D=(4,3)\)

Add 5 less than E and F's y-coordinates.

\(C= (-1-2-5)\)

\(C=(-1,-7)\)

\(D= (4,-2-5)\)

\(D=(4,-7)\)

As a result, the coordinates for the additional pairings are (-1, 3), (4, 3), and (-1, -7), respectively (4, -7) No third pair is present.

When two or more curves, lines, or edges come together, it is called a vertex (plural: vertices or mostly including) in geometry. As a result of this description, vertices are the intersection of two planes that create an angles as well as the edges of polygon and polygonal.

Equation of the line which passes through the point (-4,5) and the slope of the line is 0 is equal to y = 0x + 5.

As given in the question,

Line passes through the point ( -4 , 5) and the slope of the line is equal to 0.

Standard equation of the line passes through the point ( x₁ , y₁) and slope m is given by :

( y -y₁ ) / ( x - x₁ ) = m

Substitute the given value of the point ( x₁ , y₁)  = ( -4, 5 ) and slope m = 0 in the standard form we get,

( y - 5 ) / ( x - (-4)) =0

⇒ ( y - 5 ) = 0( x +4)

⇒ y = 0x + 5

Therefore, equation of the line which passes through the point (-4,5) and the slope of the line is 0 is equal to y = 0x + 5.

The future value of the $10,000 investment after 7 years, at an interest rate of 6% per year, compounded annually, is approximately $14,185.10.

To calculate the future value (FV) of an investment of $10,000 at an interest rate of 6% per year, compounded annually, after 7 years, we can use the formula:

FV = P(1 + r)^n

Where:

P is the principal amount (initial investment) = $10,000

r is the interest rate per period = 6% = 0.06

n is the number of periods = 7

Plugging in the values, we have:

FV = $10,000(1 + 0.06)^7

Calculating the expression inside the parentheses first:

(1 + 0.06)^7 ≈ 1.41851

Now, multiply the principal amount by the calculated expression:

FV ≈ $10,000 * 1.41851 ≈ $14,185.10

Therefore, the future value of the $10,000 investment after 7 years, at an interest rate of 6% per year, compounded annually, is approximately $14,185.10.

Using the properties of multiplication to compare the expressions 3 to the eighth power and 3 to the fifth power x 3 to the third power, it can be seens that that the two expressions are equal to each other.

The properties of multiplication state that when multiplying two expressions with the same base, we can add their exponents together. This means that 3 to the fifth power x 3 to the third power is equal to 3 to the eighth power.

In mathematical notation, this looks like:

3^8 = 3^5 x 3^3

Using the properties of multiplication, we can add the exponents together:

3^8 = 3^(5+3)

Simplifying the exponent:

3^8 = 3^8

This shows that the two expressions are equal to each other. Therefore, we can conclude that 3 to the eighth power and 3 to the fifth power x 3 to the third power are the same value.

The required answer is the value of tan(2) is approximately -2352/3669.

To evaluate the expression under the given conditions, we will first determine the value of sin() using the Pythagorean identity and then use the double-angle formula for tan(2).
A Quadrant is circular sector of equal one quarter of a circle ,or  a half semicircle. A sector of two-dimensional cartesian  coordinate system.  The Pythagorean identity, are useful expression involving the function need to simplified.

Given: cos() = 7/25, and is in Quadrant I.
Step 1: Find sin()
Since we are in Quadrant I, sin() is positive. Using the Pythagorean identity, sin^2() + cos^2() = 1, we can find sin().
sin^2() + (7/25)^2 = 1
sin^2() = 1 - (49/625)
sin^2() = (576/625)
sin() = √(576/625) = 24/25

we  are called the Pythagorean identity is  Pythagorean trigonometric identity, is expression A to B .

The same value for all variables within certain range. Angle is double or multiply by 2 so we called double- angle.

Step 2: Find tan(2) using the double-angle formula
The double-angle formula for tangent is: tan(2) = (2 * tan()) / (1 - tan^2())
First, we find tan():
tan() = sin() / cos() = (24/25) / (7/25) = 24/7
Now, use the formula for tan(2):
tan(2) = (2 * (24/7)) / (1 - (24/7)^2)
tan(2) = (48/7) / (1 - 576/49)
tan(2) = (48/7) / ((49 - 576) / 49)
tan(2) = (48/7) * (49 / (-527))
tan(2) = (-2352 / 3669)
So, under the given conditions, the value of tan(2) is approximately -2352/3669.

To find the final location of the ant after it has walked counterclockwise a distance of 2 units around the unit circle, we need to calculate the coordinates (x, y) of the point.

Since the ant starts at the point (1, 0) on the unit circle, we can think of this point as being at an angle of 0 degrees or 0 radians.

To find the coordinates after walking a distance of 2 units counterclockwise, we can calculate the new angle using the arc length formula:

s = rθ

where s is the arc length, r is the radius of the circle (which is 1 in this case), and θ is the angle in radians.

In this case, the arc length is 2 units and the radius is 1, so we have:

2 = 1θ

Solving for θ, we find:

θ = 2 radians

Now, we can use this angle to find the coordinates (x, y) of the final location on the unit circle:

x = cos(θ)

y = sin(θ)

Plugging in θ = 2, we get:

x = cos(2) ≈ -0.42

y = sin(2) ≈ 0.91

Therefore, the approximate coordinates of the final location of the ant are (-0.42, 0.91).
