Answer:

Vertical distance between dolphin and the bird is 7.9 meters.

Step-by-step explanation:

Eva sees a Dolphin at the distance 3.2 meters below the sea level.

At the same time she sees a bird [tex]\frac{47}{10}[/tex] meters above the sea level.

Therefore, vertical distance between the dolphin and the bird = Distance of dolphin below the sea level + Distance of the bird above the sea level

= 3.2 + [tex]\frac{47}{10}[/tex]

= 3.2 + 4.7

= 7.9 meters

Answer is 7.9 meters.

0 ≠ 4. The equation is wrong, and has no true solution.

8x + 3 - 10x = -2(x - 2) + 3

Distributive property.

8x + 3 - 10x = -2x + 4 + 3

Combine like terms.

-2x + 3 = -2x + 7

Cancel like terms.

Subtract 3 from both sides.

ANSWER

Multiplicative Inverse

EXPLANATION

If we multiply any number by its multiplicative inverse, the result is 1.

So for the given equation

[tex]3\times N=1[/tex]

[tex]N[/tex] is the multiplicative inverse of [tex]3[/tex]. That is why the result is [tex]1[/tex]

Answer:

C. Multiplicative inverse.

Step-by-step explanation:

We have been given an equation [tex]3\cdot N=1[/tex]. We are asked to find the name of N.

We can see that N is multiplied by 3 and the result is 1.

We know that a number is known as multiplicative inverse of another number, when the product of both numbers equal to 1.

Since product of 3 and N is 1, therefore, N is multiplicative inverse for our given equation.

range is {- 27, - 15, - 3, 9 }

substitute each of the values from the domain into the equation for x and solve for y

These values are the range

x = - 2 : y = - 12 - 15 = - 27

x = 0 : y = 0 - 15 = - 15

x = 2 : y = 12 - 15 = - 3

x = 4 : y = 24 - 15 = 9

ANSWER

The orthocenter is [tex](-4,8)[/tex]

EXPLANATION

The orthocenter is  the point of intersection of all the altitudes of a triangle.

If it is a right angle triangle then the orthocenter is the point at which the right angle is made.

If it is not a right angle triangle, then you have to find the equations of any two of the altitudes and solve simultaneously.

So you must first check to see if it is a right angle triangle that way you do not have to do bunch work.

The given triangle has vertices [tex]J(-4,-1)[/tex], [tex](-4,8)[/tex], and [tex]L(2,8)[/tex].

[tex]Slope_{JK}=\frac{8--1}{-4--4}[/tex]

[tex]Slope_{JK}=\frac{8+1}{-4+4}[/tex]

[tex]Slope_{JK}=\frac{9}{0}[/tex]

Since the denominator is zero, the slope is undefined.

If the slope of a straight line is undefined, then that line is parallel to the y-axis. In other words, it is a vertical line.

[tex]Slope_{JL}=\frac{8--1}{2--4}[/tex]

[tex]Slope_{JL}=\frac{8+1}{2+4}[/tex]

[tex]Slope_{JL}=\frac{9}{6}[/tex]

[tex]Slope_{JL}=\frac{3}{2}[/tex]

[tex]Slope_{KL}=\frac{8-8}{2--4}[/tex]

[tex]Slope_{KL}=\frac{0}{2+4}[/tex]

[tex]Slope_{KL}=\frac{0}{6}[/tex]

[tex]Slope_{KL}=0[/tex]

if a straight line has a slope of zero, that line is parallel to the x-axis or it is horizontal.

From the slopes we can see that side KL of the triangle is horizontal and side JK is vertical. This two sides will meet at right angles at K.

See graph.

Therefore the coordinates of K, [tex](-4,8)[/tex] is the orthocenter of the given triangle.

The trajectory of a projectile is proven to be parabolic by eliminating time from the horizontal and vertical motion equations to receive the form y = ax + bx², thus describing the projectile's path.

To prove the trajectory of a projectile is parabolic, we start with the motion equations given for horizontal and vertical positions, which are x = V0x t and y = V0y t - (1/2)gt2, respectively.

First, we solve the horizontal motion equation for t to find t = x/V0x.

We then substitute this expression for t into the vertical position equation to eliminate t.

After substitution, we get an equation of the form y = ax + bx2, where a is V0y/V0x and b is -g/(2V0x2).

These constants a and b represent the initial velocity components and the acceleration due to gravity, which together describe the parabolic path of a projectile motion.

The equation of the parabola is: y = 0(x - (-2.5))^2 + 2

To determine the equation of the parabola, we can use the general form of the equation for a parabola:

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

where (h, k) represents the vertex of the parabola.

Given two points on the graph, (-2,2) and (-3,4), we can use these points to find the values of h and k.

Let's start by finding the x-coordinate of the vertex, h. Since the parabola is symmetric, the x-coordinate of the vertex is the average of the x-values of the two given points:

h = (-2 - 3)/2 = -5/2 = -2.5

Next, let's find the y-coordinate of the vertex, k. We substitute the x-coordinate of the vertex into the equation and solve for y:

2 = a(-2.5 - (-2.5))^2 + k

Simplifying:

2 = a(0)^2 + k
2 = k

Therefore, the vertex of the parabola is (-2.5, 2).

Now that we have the values of h and k, we can substitute them into the equation to find the value of a. Using one of the given points, (-2,2), we have:

2 = a(-2 - (-2.5))^2 + 2
2 = a(-2 + 2.5)^2 + 2
2 = a(0.5)^2 + 2
2 = 0.25a + 2
0.25a = 0
a = 0

Therefore, the equation of the parabola is:

y = 0(x - (-2.5))^2 + 2

Simplifying:

y = 2

In this case, the parabola is a horizontal line passing through the vertex at y = 2.

For simplifying an expression like this where the same bases with different exponents are to be multiplied, remember the Product rule. It says that when multiplying two or more powers having the same base (x and y in this case), you must add the exponents. For example, here in this expression there are two x's and two y's with different powers so you can simple add the powers of x and for y like shown below:

x^-4×y^3×x^4×y^2

= x^(-4+4) × y^(3+2)

=x^1 × y^5

since x^1 = x so we can omit the power 1 and write x instead.

xy^5 (here the power 5 only raises y and not x since it is not applied to whole)

Answer:

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Step-by-step explanation:

Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.

Let flat rental fee be c and cost per mile driven = m and miles driven = x

Total cost =y

Then y = mx+C is the linear equation.

to find m and c, we use the fact that y =110.30 when x = 222

i.e. 110.30 = c+222x

and similarly 99.05 = c+147x

Subtract to eliminate c

11.25 = 75 x

0.15 =x

Substitute in I equation

110.30 = c+222(0.15)

c = 77

Hence y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Answer:

y = 0.15x+77

You multiply by 1.12 to find your answer

Answer: 1.12

To get this answer, you would represent 12% as 0.12 (move the decimal point 2 spots to the left to go from 12.0% to 0.12) then you add on 1 to get 1+0.12 = 1.12

Another way to think about it is to have 100% + 12% = 112%, so the new price is 112% of the old price. For example, if the car was $100 and you increase the price by 12%, then it jumps to $112. Notice how 1.12*(old price) = 1.12*100 = 112 = new price

We are given a side of the rectangle = 11 m.

Let us assume other side of the rectangle = x meter.

We know,  formula for Perimeter of the rectangle :

Periemter = 2×one side + 2× other side .

We are given perimeter = 143 m.

Therefore,

2 × 11 + 2 × x = 143

22 +2x =143.

Therefore, (d) 2x + 22 = 143 equation can be used to determine the length of the longer side of the rectangle.
