Answer:

7/4

Step-by-step explanation:

The slope of Q is (9-5)/(3-10) = -4/7

Perpendicular lines' slopes are opposite reciprocals of eachother (so the +/- changes and then x/y becomes y/x).

This means the slope of R is 7/4

The required slope of line R will be 7/4.

Perpendicular lines are two lines that cross one other and create a 90-degree angle.

Two lines are perpendicular if the product of their slopes is -1.

The line Q is given which passes through points (3,9) and ( 10,5)

Let

x₁ = 3,  y₁ = 9

x₂ = 10, y₂ = 5

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Substitute values in the formula

The slope of line Q will be:

m = (9-5)/(3-10)

m = -4/7

Since line R is perpendicular to Q, so the slope of line R will be

⇒ -1/m

⇒ -1/(-4/7)

Reciprocal the term in the denominator,

⇒ -1 × -7/4

Apply the multiplication operation, and we get

⇒ 7/4

Therefore, the required slope of line R will be 7/4.

Explanation:

In a right triangle the longest side is the hypotenuse. In this case the length is 5 units.

The hypotenuse is opposite to the right angle.

You must draw a small square inside the right angle. In the figure the right angle is labeled C.

The other two sides are the legs: in this case their lengths are 3units and 4 units.

The side with the shortest length is opposite to the smallest angle; the side with the intermediate length is opposite to the angle with the intermediate measure.

The vertices are marked with capital letters. I used A, B, and C.

With this explanation you can understand the figure attached and build one on your own.

Answer:

I would say Graph 2 because if its showing f(x)=x2+5

there are no negatives in this equation, so I think it is graph 2

The graph of the function is attached to the solution.

The given equation is f(x) = x²+5, the power on the variable is 2, that means the equation is a quadratic equation therefore, the graph will be a parabola,

Since, there is no negative sign so, the parabola will be opened up,

Also, there are 5 units added in the equation that mean the parabola will be 5 units up from the origin.

So, the graph will be an upward opened parabola with its vertex at (0, 5)

Answer:

Step-by-step explanation:

Let the number be A

Given 6 times A is 12+ (4 xA)

That’s

6 x A = 12 + 4A

6A = 12 + 4A

Subtract 4A from both sides

6A - 4A = 12 - 4A - 4A

2A = 12

Divide both sides by 2

A = 12/2

A = 6

Answer:

29000

Step-by-step explanation:

Nearest thousand means the thousand at which the digit is nearest to. Now in approximation, we round up numbers from 1 to 4, to Zero while numbers from 5 to 9 are rounded up to 1.

28913 is between thousand 28,000 and 29000.

And then to be rounded up to the nearest thousand, the digit 9, before the thousand digit 8, in the number 28913 will therefore will rounded up to 1 and added to the thousand digit 28.

We therefore have 29,000

Equity at the end of the year = $130,000

Step-by-step explanation:

Step 1:

Given ,

Asset of the company at beginning of year = $300,000

Equity  of the company at beginning of year = $100,000

Increase of the assets  during the year = $80,000

Increase of the liabilities  during the year =  $50,000

We need to find the equity at the year end.

Step 2 :

The equity at any point can be obtained by using the formula

equity = assets - liability

At the beginning of the year ,

100,000 = 300,000 - liability

So liability = 300,000 - 100,000 = 200,000

Step 3 :

During the year, assets increase $80,000 and liabilities increase $50,000

So assets at the year end = 300,000 + 80,000 = $380,000

liabilities at the year end = 200,000 + 50,000 = $250,000

Therefore

Equity at the year end = 380,000 - 250,000 = $130,000

Step 4 :

Answer :

Equity at the year end = $130,000

The solution of the system of equations is [tex]x=-2[/tex] and [tex]y=3[/tex]

Explanation:

The system of equations are [tex]4 x+5 y=7[/tex] and [tex]3 x-2 y=-12[/tex]

To determine the solution of the equation, let us solve the equations by elimination method.

Thus, multiplying the equation [tex]4 x+5 y=7[/tex] by 2, we get, [tex]8x+10y=14[/tex]

Multiplying the equation [tex]3 x-2 y=-12[/tex] by 5, we get, [tex]15x-10y=-60[/tex]

Adding these two equations, we have,

[tex]\ \ 8x+10y=14\\15x-10y=-60\\---------\\23x=-46[/tex]

Dividing both sides by 23, we have,

[tex]\frac{23x}{23} =\frac{46}{23}[/tex]

  [tex]x=-2[/tex]

Thus, the value of x is [tex]x=-2[/tex]

Substituting [tex]x=-2[/tex] in the equation [tex]4 x+5 y=7[/tex], we get,

[tex]4 (-2)+5 y=7[/tex]

    [tex]-8+5 y=7[/tex]

             [tex]5y=15[/tex]

               [tex]y=3[/tex]

Thus, the value of y is [tex]y=3[/tex]

Hence, the solution of the system of equations is [tex]x=-2[/tex] and [tex]y=3[/tex]

The solution to the system of equations, is: (-2, 3).

To find the solution, you can use the elimination method by first making both equations equivalent. Then add or subtract to eliminate a variable.

Given:

Multiply eqn. 1 by 3 and eqn. 2 by 4:

12x + 15y = 21 --> Eqn. 1

12x – 8y = –48 --> Eqn. 2

23y = 69

y = 3

Substitute y = 3 into eqn. 1.

4x + 5(3) = 7

4x + 15 = 7

4x = 7 - 15

4x = -8

x = -2

Therefore, the solution to the system of equations, is: (-2, 3).

Answer:

182.25 J

Step-by-step explanation:

KE = (0.5)*m*v^2

KE = (0.5)*(0.18 kg)*(45 m/s)^2

KE = 182.25 Joules

Hope this helps!

Final answer:

The kinetic energy of a 0.18 kg ball moving at 45 m/s is calculated using the formula KE = (1/2)mv² and is found to be 182.25 joules.

Explanation:

The kinetic energy (KE) of an object is calculated using the formula KE = (1/2)mv², where m is the mass of the object and v is its velocity. For a ball with a mass of 0.18 kg moving at a velocity of 45 m/s, we can find its kinetic energy by substituting these values into the formula.

KE = (1/2) imes 0.18 kg  imes (45 m/s)²

= 0.09 kg imes 2025 (m/s)²

= 182.25 joules

Therefore, the kinetic energy of the ball is 182.25 joules.

The balance after 2 years will be $1872.72.

To find the balance after 2 years when you deposit $1800 into a savings account that earns 2% interest compounded annually, we can use the compound interest formula:

[tex]\[ A = P(1 + r)^n \][/tex]

Where:

- A is the amount of money accumulated after n years, including interest.

- P is the principal amount (the initial amount of money).

- r  is the annual interest rate (expressed as a decimal).

- n is the number of years the money is deposited for.

Given:

[tex]- \( P = $1800 \)[/tex]

[tex]- \( r = 2\% = 0.02 \)[/tex] (expressed as a decimal)

[tex]- \( n = 2 \)[/tex] years

Plug these values into the formula and solve for A :

[tex]\[ A = 1800(1 + 0.02)^2 \][/tex]

[tex]\[ A = 1800(1.02)^2 \][/tex]

[tex]\[ A = 1800(1.0404) \][/tex]

To add that up, you get two hundred fourteen and thirteen thousandths.

Answer:

The woman invested $15,000 at 7% interest rate and $5,000 at  6% interest rate.

Step-by-step explanation:

We are given the following in the question:

Let x be the interest earned from 7% interest rate and y be the interest earned from 6% interest rate.

The woman invested has three times as much invested at 7% as she does at 6%.

Thus, we can write the equation:

[tex]x = 3y[/tex]

The total interest is $1,350.

Thus, we can write the equation:

[tex]1350 = \dfrac{7x}{100} + \dfrac{6y}{100}\\\\7x + 6y = 135000[/tex]

Solving the two equations by substitution method:

[tex]7(3y) + 6y = 135000\\27y = 135000\\y = 5000\\x = 3(5000) = 15000[/tex]

Thus, she invested $15,000 at 7% interest rate and $5,000 at  6% interest rate.

Answer:

(-4,1)

Step-by-step explanation:

The given parabola is

[tex]y = - \frac{1}{4} {x}^{2} - 2x - 2[/tex]

When we rewrite in vertex form, we get;

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

Or

[tex]{(x + 4)}^{2} = - 4( y - 2)[/tex]

When we compare to:

[tex]{(x - h)}^{2} = 4p( y - k)[/tex]

We have 4p=-4

This means p=-1

But the vertex is at:

(-4,2)

Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.

Hence the focus is (-4,1)
