20 points What is the equation of a line parallel to the given line with an X intercept of 4

Answer:

$2.14

Step-by-step explanation:

First, set up a proportion.

x over 3.29 equals 35 over 100.

You are trying to find what out of 3.29 is 35 percent.

Cross multiply and divide.

3.29 times 35 = 115.15

115.15 divided by 100 = 1.1515

Round to the nearest hundredth because you are dealing with money.

$1.15

Because you are looking for the sale price, you must add or subtract $1,15 from the original amount which is $3.29.

In this case, you must subtract because it is a markdown. You are taking an amount off of the original price.

$3.29 - $1.15 = $2.14

The final price is 2 dollars and 14 cents

Answer:

Sides of FE = 8 units.

Step-by-step explanation:

Median of any triangle is the line segment that joins any vertex of the triangle with the mid-point of its opposite side.

In the given figure, the median from G meets the mid-point of the opposite side FE, at point T.

Since, GT is the median of ΔFGE and it bisects the side FE into two halves where FT=TE

Given: TE = 8 units.

FE = FT + TE

Since, FT = TE

FE = 2 TE = 2(8) = 16 units.

Therefore, the sides of FE = 8 units.

The system of linear equations x - y = 7 and 0.5x + y = 5 can be solved by first rearranging into y = mx + b form and graphing. Intersecting point of the two lines is the solution. In such equations, y is the dependent variable, relying on x, the independent variable.

You've been asked to solve the system of linear equations by graphing. The pair of equations you're given are: x - y = 7, and 0.5x + y = 5. Let's start by expressing these equations in the form y = b + mx.

For x - y = 7, you can rearrange it as y = x - 7 where the slope (m) is 1 and the y-intercept (b) is -7.

For 0.5x + y = 5, you can rearrange it as y = -0.5x + 5 where the slope (m) is -0.5 and the y-intercept (b) is 5.

Now you must graph these two lines on the same graph. Where these two lines intersect, that is the solution of the system of equations.

When graphing these lines, start at the y-intercept (b) and use the slope (m) to find additional points. The slope is a ratio representing the vertical change in y for each unit of horizontal change in x.

Expressing Equations Graphically in this way can help visually solve the system of equations.

Also note that, in each equation, y is the dependent variable since its value relies on the value of x, the independent variable.

Answer:

The cell phone took 4.7 seconds to reach the ground.

Step-by-step explanation:

A hang glider dropped his cell phone from a height of 350 feet:

Initial velocity: Vo = 0 ft/s

Height: h = 350 feet = 350 ft

Time to reach the ground: t=?

Gravity's acceleration: g = 32 ft/s^2

h = Vo t + g t^2 / 2

Replacing the known values in the equation above:

350 ft = (0 ft/s) t + (32 ft/s^2) t^2 /2

350 ft = 0 + (16 ft/s^2) t^2

350 ft = (16 ft/s^2) t^2

Solving for t^2: Dividing both sides of the equation by 16 ft/s^2:

(350 ft) / (16 ft/s^2) = (16 ft/s^2) t^2 / (16 ft/s^2)

21.875 s^2 = t^2

Solving for t: Square root both sides of the equation:

sqrt(21.875 s^2) = sqrt(t^2)

4.677071733 s = t

t = 4.677071733 s

Rounding to the nearest tenth:

t = 4.7 s

The cell phone takes about 4.7 seconds to reach the ground

Acceleration is rate of change of velocity.

[tex]\large {\boxed {a = \frac{v - u}{t} } }[/tex]

[tex]\large {\boxed {d = \frac{v + u}{2}~t } }[/tex]

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

Given:

Height = h = 350 feet

Gravitational Acceleration = g = 32.2 feet/s²

Initial Velocity = u = 0 m/s

Unknown:

time taken to reach the ground = t = ?

Solution:

This problem is about Free Fall.

When an object experiences free fall, the acceleration experienced by the object is the same as the acceleration due to gravity which is equal to 9.8 m/s² or 32.2 feet/s²

[tex]h = ut + \frac{1}{2}gt^2[/tex]

[tex]350 = 0t + \frac{1}{2}(32.2)t^2[/tex]

[tex]350 = 0 + 16.1t^2[/tex]

Step-by-step explanation:

For shirt :

Original cost = $54

New cost = $18

Change amount = 54 - 18 = $36

% INC/DEC = (36 /54) * 100 = 2 * 100 / 3 = 66.66%

For PS4 :

Original cost =$400

New cost = $250

Change in amount = 400- 250 =$150

% INC/DEC = (150/400) * 100 = 37.5%

For Coffee maker:

Original cost = $30

New cost = $20

Change in amount = 30 - 20 = $10

% INC/DEC = (10/30)*100 = 33.33 %

For Luggage:

Original cost = $180

New cost = $50

Change in amount = 180 - 50 = $130

% INC/DEC = (130/180)*100 = 72.22 %

Answer:

Correct answer is option (B)

Step-by-step explanation:

We have been given that area of Maxine's living room is 88 square feet. Further, we are given that length of the room is 3 feet longer than the width.

Let us assume that x be the width of the room, therefore, length of the room will be [tex]x+3[/tex].

We know that area of a rectangle can be found by multiply the measures of length and width, therefore, we can set:

[tex]\text{Area} = \text{length}\times \text{width}\\\text{Area} = (x+3)\times x\\\text{Area} = x^{2}+3x\\[/tex]

Now, since we are given that area is 88 square feet, therefore, we can set this expression for area equal to 88 to get the desired equation:

[tex]x^{2}+3x=88[/tex]

Therefore, correct answer is option (B)

Answer:

Amount of gas that can be hold by Joe's tank = 16 gallons.

Step-by-step explanation:

Given that Joe's gas tank is 1/4 full. After he buys 6 gallons of gas, it is 5/8 full. Now we need to find about how many gallons can Joe's tank hold.

So let's find change that happened after filling the gas.

Change = (5/8 full) - (1/4 full)

Change = (5/8 - 1/4)  full

Change = (5/8 - 2/8)  full

Change = (5 - 2)/8  full

Change = 3/8  full

So that means 3/8 full happens in 6 gallons

then 1 full will happen in 6/(3/8) gallons = 6*(8/3) gallons = 48/3 gallons = 16 gallons

So the amount of gas that can be hold by Joe's tank = 16 gallons.

To solve 924 ÷ 4, we simply divide 924 by 4. So, 924 divided by 4 equals 231.

When we're dividing one number by another, we're essentially figuring out how many times the divisor (the number you're dividing by) fits into the dividend (the number you're dividing).

In this case, we're dividing 924 by 4. We start by asking ourselves, "How many times does 4 fit into 9?" Since 4 doesn't fit into 9 evenly, we move to the next digit and consider 92. 4 fits into 92 twenty-three times (4 x 23 = 92).

Then, we subtract 92 from 924, which leaves us with 32. Now, we bring down the next digit, which is 4, and we consider how many times 4 fits into 324. 4 fits into 32 eight times (4 x 8 = 32).

So, we've found that 4 fits into 924 exactly 231 times without any remainder. Therefore, 924÷4=231.

Complete Question:

What is 924 divided by 4 ?

Answer:

The solution is (-5,4).

Step-by-step explanation:

We are given the equation, |x+1|=|-x-9|

Now, |x+1| = [tex]\left\{\begin{matrix}x+1 & ,x>0\\ -(x+1)& ,x<0\end{matrix}\right.[/tex]

Also, |-x-9| = [tex]\left\{\begin{matrix}-x-9 & ,x>0\\ -(-x-9)& ,x<0\end{matrix}\right.[/tex]

So, equating these two functions gives the value of x = -5. After substituting this value in any of the function term say y = x+1, we get y = 4.

Moreover, from the graph below we see that, after equating these functions, the solution is given by the points at which they intersect.

Hence, the solution is (x,y) = (-5,4).

Final Answer:

The equations of the tangents to the curve[tex]\(x = 9t^2 + 6, y = 6t^3 + 3\)[/tex]that pass through the point (15, 9) are [tex]\(y = 2x - 21\)[/tex] and[tex]\(y = -2x + 51\).[/tex]

Explanation:

To find the equations of the tangents, we first substitute (x = 15) and (y = 9) into the parametric equations[tex]\(x = 9t^2 + 6\)[/tex] and [tex]\(y = 6t^3 + 3\)[/tex]. Solving for (t), we get (t = 1) and (t = -1). These values of (t) correspond to the points of tangency.

Next, we find the slopes of the tangents by taking the derivatives of (x) and (y) with respect to (t), resulting in (dx/dt = 18t) and (dy/dt = 18[tex]t^2[/tex]). At (t = 1), the slope is (18), and at (t = -1), the slope is (-18).

Using the point-slope form of a linear equation [tex]\(y - y_1 = m(x - x_1)\)[/tex], where (m) is the slope and [tex]\((x_1, y_1)\)[/tex] is the point of tangency, we obtain the equations of the tangents: (y - 9 = 18(x - 15)) and (y - 9 = -18(x - 15)). Simplifying these expressions yields (y = 2x - 21) and (y = -2x + 51).

a) g(-x) = -55/x - 3x

b) -g(x) = -55/x - 3x

c) -g(-x) = 55/x + 3x

For both functions f and g, we found the values of f(-x), -f(x), -f(-x), g(-x), -g(x), and -g(-x) by substituting -x into the original functions and negating the functions where necessary.

1. For the function f defined by f(x) = x^2 + 2x + 3:

a) To find f(-x), we substitute -x into the function:

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

b) To find -f(x), we negate the entire function:

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

c) To find -f(-x), we substitute -x into the negated function:

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

2. For the function g defined by g(x) = 55/x + 3x:

a) To find g(-x), we substitute -x into the function:

g(-x) = 55/(-x) + 3(-x) = -55/x - 3x

b) To find -g(x), we negate the entire function:

-g(x) = -(55/x + 3x) = -55/x - 3x

c) To find -g(-x), we substitute -x into the negated function:

-g(-x) = -(-(55/(-x)) + 3(-x)) = -(-55/x - 3x) = 55/x + 3x

The ratio of the height of the building to the number of floors is 13 feet/floor, i.e., each floor of the building is approximately 13 feet tall.

Given the information that a single building with 8 floors measures 104 feet in height, we can calculate the ratio of the height of the building to the number of floors as follows:

104 feet / 8 floors = 13 feet/floor

This ratio or unit rate represents the height corresponding to one floor. In plain terms, this means each floor of the building is approximately 13 feet tall.
