A point extending forever in one direction

A ray is a portion of a line which starts at a point and goes off in a particular direction to infinity.

In the equation y = 3/4x -3, 3/4 is the slope and -3 is the y-intercept. To graph this, start at -3 on the y-axis, then for each increase of 1 in the x direction, go up by 3/4 in the y direction, drawing a line through these points.

The equation y = 3/4x - 3 represents a straight line in mathematics. The first step to getting your graph is to understand the equation structure: y = mx + b, in which 'm' is the slope and 'b' is the y-intercept. Hence, in your equation the slope is 3/4 and the y-intercept is -3. When x = 0, y will be -3. This is your starting point on the graph.

To construct the graph of this equation, you'd use the slope (3/4), which means to every 1 unit increase in 'x', 'y' will increase by 3/4 units. Start at your y-intercept (-3), then rise 3 units and run 4 units to the right to plot your next point. Continue this until you have a several points. Once you have enough points, you can draw a line through them to represent the equation y = 3/4x - 3.

When, a rectangle has an area of 364.5cm² if it’s length is 27 cm. Then, the perimeter of the rectangle is 81 cm.

To find the perimeter of a rectangle when the area and the length are known, first calculate the width using the area formula. The area of a rectangle is given by the formula Area = length x width. Given that the area is 364.5 cm² and the length is 27 cm, the width can be found as follows:

Width = Area / Length = 364.5 cm² / 27 cm = 13.5 cm

Once you have both the length and width, the perimeter can be calculated using the formula Perimeter = 2 x (length + width). So, the perimeter would be:

Perimeter = 2 x (27 cm + 13.5 cm) = 2  x 40.5 cm = 81 cm

Hence, the perimeter of the rectangle is 81 cm.

Final answer:

To find the height of the mountain, the tangent of the angle of elevation is multiplied by the distance to the base of the mountain. With an angle of 23°29' and a distance of 16,194.6 feet, the height of the mountain is approximately 7,026 feet.

Explanation:

To find the height of the mountain when Bob is 16,194.6 feet from the mountain's base and the angle of elevation is 23°29', we can use trigonometry, specifically the tangent function which is the ratio of the opposite side to the adjacent side in a right triangle.

Steps to Solve:

Convert the angle 23°29' to decimal degrees: 23° + 29'/60 = 23.483°.

Use the tangent function: tan(angle) = opposite side/adjacent side, where the adjacent side is the distance from Bob to the base of the mountain and the opposite side is the height of the mountain.

Calculate the height: height = tan(angle) * distance to the base.

Substitute the known values and solve: height = tan(23.483°) * 16,194.6 feet.

Using a calculator, tan(23.483°) ≈ 0.4338. Multiplying this by 16,194.6 gives us approximately 7026.03668 feet.

Therefore, the height of the mountain to the nearest foot is 7,026 feet.

The large bag of pretzels is the better buy as it has a lower cost per ounce at $0.1993 compared to $0.2475 per ounce for the small bag.

To determine which bag of pretzels is the better buy, we need to calculate the cost per ounce for each bag. For the small bag, we divide $0.99 by 4 ounces to get the cost per ounce. For the large bag, we divide $2.99 by 15 ounces to find its cost per ounce. Once we have both costs per ounce, we can compare them to see which bag offers the lower cost per ounce and hence the better value.

For the small bag:

$0.99 / 4 ounces = $0.2475 per ounce

For the large bag:

$2.99 / 15 ounces = $0.1993 per ounce

Comparing the two, we can see that the large bag of pretzels offers a lower cost per ounce and is therefore the better buy.

To round 936,292 to the nearest hundred thousand, you look at the ten thousand place. Since it's 3, which is less than 5, 936,292 rounds down to 900,000.

To round 936,292 to the nearest hundred thousand, we need to look at the ten thousand digit, which is 3. Since this number is less than 5, we do not round up the hundred thousand digit. Therefore, 936,292 rounded to the nearest hundred thousand is 900,000.

Rounding to the nearest hundred thousand means replacing all the digits to the right of the hundred thousand place with zeros. If the digit in the ten thousand place is five or higher, we add one to the hundred thousand digit. If it's lower than five, we keep the hundred thousand digit the same.

Answer:

  The interest rate = 6 %

Explanation:

We have  I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.

 Here principal, p = 200 $

          Number of years , t = 3

        Interest received, I = 36$

       We need to find rate of interest.

Substituting

       36 = 200 x r x 3

      r = [tex]\frac{36}{200*3}[/tex]= 0.06 = 6%

  The interest rate = 6 %

Answer:20%

Step-by-step explanation:

Let r represent rate of interest.

We have been given that Mika invested $200 into a certificate of deposit. After 6 months, the balance was $220.

We will use simple interest formula to solve our given problem.

I = Amount of interest,

P = Principal amount,

r = Rate of interest in decimal form,

t = Time in years.

First of all, we will find amount of interest by subtracting $200 from $220 as:

6 month = 1/2 year = 0.5 year

Upon substituting our given values in simple interest formula, we will get:

Upon dividing both sides by $100, we will get:

Since interest rate is given in decimal, so we will multiply 0.2 by 100 to convert our answer in percentage.

Therefore, the interest rate on the deposit was 20% and option B is the correct choice.

One Solution: Simplify to get 5x+4=5x+4

The equation 4x + x + 4 = 8x - 3x + 4 has infinitely many solutions.

To solve the equation 4x + x + 4 = 8x - 3x + 4, we first simplify both sides

5x + 4 = 5x + 4

Next, we subtract 5x from both sides:

4 = 4

Since the equation simplifies to a true statement (4 = 4), this means that the equation is true for any value of x.

Hence, the equation has infinitely many solutions.

Given

A laboratory technician needs to make a 117-liter batch of a 20% acid solution.

 How much the  technician combine  an acid solution that is pure acid with another that is 10% to get the desired concentration.

To proof

let us assume that the solution that is pure acid = x liters

let us assume that the anthor solution that is 10% = y liters

Than

the  equation becomes

x + y = 117

As given in the question

technician needs to make a 117-liter batch of a 20% acid solution

laboratory technician combine  an acid solution that is pure acid with another that is 10% to get the desired concentration

Convert 20% in the simpler form

[tex]=\frac{20}{100}[/tex]

= 0.2

Convert 10% in the simpler form

[tex]=\frac{10}{100}[/tex]

= 0.1

Than the equation becomes

0.2 × 117 = x + 0.1y

234 = 10x + y

Than the two equation are  

x + y = 117

234 = 10x + y

subtracted x + y = 117 from 234 = 10x + y

10x+y -x -y = 234 -117

9x = 117

x= 13

put this in the equation x + y = 117

13 + y =117

y = 117 - 13

y = 104

Therefore

The solution that is pure acid be 13 liters.

than the other solution that is 10% is 104 liters.

Hence proved

answer is 2720

solution below

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year.

solving our equation:

A = 2000(1 + (0.045 × 8)) = 2720  

A = $2,720.00

the total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 4.5% per year for 8 years is $2,720.00

0.001 = 1 thousandth = 1/1000

We can write 1000 as 10^3. Note how 1000 has 3 zeros and the exponent for 10^3 is 3

So, 1/1000 = 1/(10^3) = (1/10)^3 = (0.1)^3

Therefore, 0.001 = (0.1)^3

0.001 rewritten as a cube = (0.1)³.

Given,

0.001 can written as

0.001 = 1/1000

We can write 1000 as 10³.

Note how 1000 has 3 zeros and the exponent for 10³ is 3

So,

1/1000 = 1/(10³) = (1/10)³ = (0.1)³

Therefore, 0.001 = (0.1)³
