Answer:

Step-by-step explanation:

The way that this function looks when graphed could be similar to the seismic waves recorded when an earthquake hits.

A logarithmic measure known as the Richter scale is used to quantify the overall energy generated during an earthquake. Each number higher on the Richter scale denotes a ten-times-stronger intensity. For instance, a magnitude 5 earthquake is ten times more powerful than a magnitude 4 earthquake.

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.

Answer:

A' = (5,7)

Step-by-step explanation:

So, we start with the original point A at (3,1), that means x = 3 and y = 1.

We move it 2 units to the right... so we're moving along the X-axis... and we're moving to the right.. so we're increasing the value of x.  That means starting with x = 3, we go 2 more units... we then get to x = 5.

In the same way, we move 6 units up... so we move along the Y-axis.  We go up, so we also increase the value of y.  Starting with y = 1, we move up by 6 units... so we are now at y = 7.

A' point is then at (5,7).

Answer:

120 votes

Step-by-step explanation:

So one way to solve this is by creating an equation to solve for x.

So we are given 4/7, that will be one side of the equation.  

And we are trying to figure out how many votes out of the 210 she received, so on the other side of the equation we will have x/210, since we are solving for x.  

So 4/7 = x/210

We want to get x alone, so we can multiply 4/7 by 210, which equals 120.

So x equals 120!

Isabel received 4/7 of the 210 votes for class treasurer, which equals 120 votes when the total is multiplied by the fraction.

The student is asking for help with a mathematics problem related to finding a fraction of a whole number. Isabel received 4/7 of the total votes cast for class treasurer, and the total number of votes cast was 210. To find how many votes Isabel received, we simply multiply 210 by 4/7:

Isabel's votes = (210) * (4/7)

Isabel's votes = 840 / 7

Isabel's votes = 120

Therefore, Isabel received 120 votes.

A.33.sample population

Answer:

Option A.

Step-by-step explanation:

step 1

we know that

The equation of the solid line is

[tex]y=5[/tex]

The solution is the shaded area above the solid line

so

The equation of the first inequality is

[tex]y\geq 5[/tex]

step 2

The equation of the dashed line is

[tex]y=x^{2} -5x+6[/tex]

The solution is the shaded area above the dashed line

so

The equation of the second inequality is

[tex]y>x^{2} -5x+6[/tex]

therefore

The system of inequalities could be

[tex]y\geq 5[/tex]

[tex]y>x^{2} -5x+6[/tex]

Answer:

(x + 3)^2 + (y + 1)^2 = 25

Step-by-step explanation:

Equation of a circle with center (h, k) and radius, r.

(x - h)^2 + (y - k)^2 = r^2

The center is (-3, -1), so h = 1, and k = 2.

(x - (-3))^2 + (y - (-1))^2 = r^2

(x + 3)^2 + (y + 1)^2 = r^2

Now we substitute x and y with the values of x and y from the given point, and we solve for r^2.

(1 + 3)^2 + (2 + 1)^2 = r^2

4^2 + 3^2 = r^2

16 + 9 = r^2

r^2 = 25

Now that we know r^2, we substitute it into the equation above.

(x + 3)^2 + (y + 1)^2 = 25

Answer:

The correct answer is,

(x + 3)² + (y +1)² = 25

Step-by-step explanation:

It is given that, What is the equation of a circle with center (-3,-1) that contains the point (1,2)

Formula;-

Equation of the circle passing through the point ( x₁,y₁) with radius r is given by,

(x - x₁)² + (y - y₁)² = r²

To find the radius of circle

r =√[ (1 --3)² + (2 --1)²]

 =√(4² + 3²)

 = √(16 + 9)

 =√25 = 5

To find the equation of the circle

(x₁, x₁) = (-3, -1) and r = 5

(x - x₁)² + (y - y₁)² = r²

(x - -3)² + (y - -1)² = 5²

(x + 3)² + (y +1)² = 25

A quantity is proportional to 18/3 if it simplifies to the same value, which is 6. The proportional quantities are 90/15, 36/6, 72/12, and 6/1, as they all simplify to 6. The quantity 36/12 is not proportional since it simplifies to 3.

To determine which quantities are proportional to 18/3, we need to find what 18 divided by 3 equals and then compare this to the given fractions to check for equivalence. Calculating 18/3 gives us 6. Now, let's examine each option:

90/15: This fraction reduces to 6, which is proportional to 18/3.

36/6: This fraction also equals 6 after simplification, so it is proportional to 18/3.

72/12: Simplifying 72/12 gives us 6, making it proportional to 18/3

6/1: 6 divided by 1 is just 6, so this too is proportional to 18/3.

36/12: Simplifying 36/12 results in 3, which is not equal to 6, so it is not proportional to 18/3.

Answer: [tex]f(2)=25[/tex]

Step-by-step explanation:

You know that the given function is:

[tex]f(x)=4x^3-x^2-5x+7[/tex]

You know that you must evaluate this function for [tex]x=2[/tex].

Then, to evaluate the function for [tex]x=2[/tex], you need to substitute this value into the given function and simplify it.

Therefore, you get:

[tex]f(x)=4x^3-x^2-5x+7\\f(2)=4(2)^3-(2)^2-5(2)+7\\f(2)=4(8)-(4)-10+7\\f(2)=32-4-10+7\\f(2)=25[/tex]

So, the answer is: [tex]f(2)=25[/tex]

Final answer:

The range of a cosine function is the set of output values the function can take, which is always between -1 and +1. This applies to the standard cosine function and is unaffected by horizontal or phase shifts. This range is consistent with the definition of the cosine function as the ratio of the adjacent side to the hypotenuse in a right triangle.

Explanation:

The range of a cosine function refers to the set of possible values that the function can output. In mathematical terms, the cosine function oscillates between +1 and -1 irrespective of any horizontal shifts or phase shifts. A horizontal shift, demonstrated in Figure 15.8 (b), where the function is shifted by an angle φ (phase shift), does not alter the range of values of the function, which remain – from its minimum value of -1 to its maximum of +1.

Similarly, in Figure 16.10, a sine function, which is related to the cosine function, also oscillates between +1 and -1 every 2π radians (a complete cycle). This oscillation represents the wave function amplitude, which in cases other than a cosine can fluctuate between +A and -A.

As illustrated in Figure 2.18, the cosine function can be visualized as the ratio of the adjacent side to the hypotenuse (Ax/A = cos A) in a right triangle, further highlighting that this ratio (and thus the range of the cosine function) is between -1 and 1.

For example, when √(1+1)* approaches 1, it is indicative that cos 0 = 1, representing one end of the cosine function's range.

Answer:

Asin(wt + φ) = c2sinwt +c1coswt

Step-by-step explanation:

Proof:

wt here is periodic where as φ is constant

taking left hand side

Asin(wt + φ)

Using trigonometric identity sin(θ+φ) = sinθcosφ +sinφcosθ

Asin(wt +φ) = A[sinwtcosφ +sinφcoswt]

                  = Asinwtcosφ +Asinφcoswt

Now as we know φ is constant

so will Asinφ and Acosφ will also be constant

let     Asinφ= c1

and Acosφ=c2

Putting in above expression, we get

Asin(wt +φ) = c2sinwt +c1coswt !

Answer:

C.

Step-by-step explanation:

A - Perpendicular lines always touch each other at least once.

B - Parallel lines never touch.

D- Not always true.

C is true. If they are not in the same plane they are skewed lines.

The true statement is C: Parallel lines are always in the same plane. Perpendicular lines do intersect, while parallel lines do not, and perpendicular lines can certainly be in the same plane. Hence, correct option C.

The question seeks to determine the accuracy of given statements about geometric relationships between. Perpendicular lines and parallel lines. Based on the provided theorems, the true statement is: C. Parallel lines are always in the same plane.

This is because if two lines are parallel, they will be equidistant from each other at all points, which can only occur if they are in the same plane. Statements A, B, and D are false.

Perpendicular lines do intersect at a 90-degree angle.

Parallel lines, by definition, never intersect as they are always equidistant.

Perpendicular lines can be in the same plane or in different planes, although a line that is perpendicular to a plane must lie in another plane.

The surface of the ocean is 0 meters.

Because the fish is below the surface it would be a negative number. ( it is less than 0)

The elevation of the fish would be -12 meters.

Answer:

-12 meters

Step-by-step explanation:

Elevation is the height above a given level, most often the sea. Therefore, elevation is like a vertical numerical line. If the sea level is 0, and to the right of the 0 is positive numbers, then the left has to be negative.

Therefore, the fish is -12 meters below sea level.

let the coordinates of other end points are (x,y)

Then mid point of (1,-2) and (x,y) is given by mid point formula:

[tex]\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]

[tex]\left(\frac{x+1}{2},\frac{y-2}{2}\right)=(-4,-2)[/tex]

Step-by-step explanation:

For this problem, we can use the formula for the area of a kite.

[tex]A=\frac{pq}{2}[/tex]

Where p and q are the diagonals.

Since line AE starts at the edge of the kite and ends at the center, we can multiply its value by 2 to find the value of the p diagonal.

[tex]6*2=12[/tex]

So diagonal p is 12ft.

Now we can find the value of the q diagonal, which will be adding BE and DE.

[tex]9+15=24[/tex]

So diagonal q is 24ft.

Let's plug them into the area formula I mentioned earlier.

A = s^2

9 = s^2

Taking the square root of each side

sqrt(9)= sqrt(s^2)

3 =s

Perimeter of a square = 16

P =4s

16 =4s

Divide each side by 4

16/4 =4s/4

4 =s

Side = 5 in

Right triangles obey the Pythagorean theorem

a^2 + b^2 = c^2

Putting the smaller sides in for a and b

3^2 +4^3 = 5^2

9+16=25

25=25

Since this is true, we can arrange the squares to make a right triangle

Answer:

Yes, due to the Pythagorean theorem.

Leg A would be 3

Leg B would be 4

Hypotenuse C would be 5

Explanation:

When making the right triangle, only one side length value is needed.

If the area of square one is 9, 9 divided by 2 is 3.

If the perimeter of square two is 16, 16 divided by 4 is 4.

The single side length for square three is given, which is 5.

The Pythagorean theorem consists of a^2 + b^2 = c^2.

Plug in the values.
