The terms of an arithmetic sequence are generated by adding a fixed term [tex]r[/tex] every time.

So, we start with [tex]a_1=15[/tex], and we continue with [tex]a_2=15+r[/tex], [tex]a_3=15+2r[/tex] and so on.

As you can see, the general rule is [tex]a_n = 15+(n-1)r[/tex]

With this information, we can derive [tex]r[/tex], knowing that

[tex]a_{100} = 307 = 15+99r \iff 99r = 292 \iff r = \dfrac{292}{99}[/tex]

So, the sum of the first 100 terms is

[tex][tex]\displaystyle \sum_{i=0}^{99} 15+i\dfrac{292}{99} = \displaystyle \sum_{i=0}^{99} 15 + \displaystyle \dfrac{292}{99}\sum_{i=0}^{99} i = (15\cdot 99) + \dfrac{292}{99}\dfrac{99\cdot 100}{2} = 1485 + \dfrac{490342}{99}[/tex]

I believe it is because it would be he most simplistic answer to be honest because for example 10,8 it is the same as 5,4 so u would put 5,4 because it is simplified so put (2.1,0) as your answer

The ordered pair that is a solution to the equation represented by the graph is (-2.5, 3).

Here's my reasoning:

- The graph intersects the x-axis at (2.1, 0): This means that any point on the x-axis, including (2.1, 0), has a y-value of 0. However, this doesn't guarantee that (2.1, 0) is a solution to the equation itself.

- The graph passes through the point (-2.5, 3): This means that the equation of the graph must yield a y-value of 3 when x = -2.5. Therefore, (-2.5, 3) is a solution to the equation.

The other points are not on the graph itself:

- (0, 0.6) is above the x-axis but not on the graph's line.

- (-1, 1.8) is also above the x-axis but not on the graph's line.

Therefore, the only ordered pair that is a solution to the equation represented by the graph is (-2.5, 3).

Answer:

0.18

Step-by-step explanation:

This is a very simple problem that can be solved with a simple formula.

When there are two independent events A and B, the formula is:

P(A and B) = P(A) * P(B)

So we just need to multiply P(A) and P(B) to get P(A and B).

Thus,

P(A and B) = P(A) * P(B) = 0.60 * 0.30 = 0.18

Answer:

P (A and B) = 0.18

Step-by-step explanation:

We are given that A and B are independent events which means that occurrence of one event does not have any impact on the other event.

Given that P(A)=0.60 and P(B)=0.30, we are to find the probability P(A and B).

To find this, we just simply need to multiply the probabilities of the two events.

P (A and B) = 0.60 × 0.30 = 0.18

x^(-a) = ----------

              x^a

For this case, we must simplify the following expression:

[tex]r ^ {- 7} + s ^ {- 12}[/tex]

By definition of power properties we have to:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

So, rewriting the expression we have:

[tex]\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}[/tex]

Answer:

[tex]\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}[/tex]

Option D

Answer:

9.4 inches

Step-by-step explanation:

The distance between the opposite corners is the diagonal.

We can find this using the Pythagorean theorem.  The diagonal is the hypotenuse.

a^2 +b^2 = c^2

8^2 +5*2 = c^2

64+25 = c^2

89=c^2

Take the square root of each side

sqrt(89) = sqrt(c^2)

sqrt(89) = c

9.433981132=c

Rounding to the nearest tenth

9.4 inches = c

Answer: Second option.

Step-by-step explanation:

As you can see in the graph attached, the lenght of the side AB is 2 units.

The formula for calculate the area of  rectangle is:

[tex]A=l*w[/tex]

Where l is the length and w is the width.

Therefore, if the area of the rectangle to be drawn is 10 square units and you know AB=2 units and CD  lies vertically below BA , then you can solve for the length:

[tex](10units^2)=(2units)l\\l=5units[/tex]

Therefore C and D are located at:

[tex]C=B(-1, 3-5)=> C(-1,-2)[/tex]

[tex]D=A(1, 3-5)=> D(1,-2)[/tex]

Answer:

The correct answer is,

Option 2).  C(-1, -2), D(1,-2)

Step-by-step explanation:

It is given that,If the area of the rectangle to be drawn is 10 square units

To find the length of rectangle

From the figure we get length of AB = 2 units

Therefore Area = length * breadth = 10

Therefore length = 10/2 = 5 units

To find the points of C and D

we have B(-1, 3)

The point C is 5 units below the point B

Therefore C(-1, 3-5) = C(-1,-2)

we have A(1, 3)

The point D is 5 units below the point B

Therefore D(1, 3-5) = A(1,-2)

Therefore the correct answer is option 2

Answer:

776.46 m

Step-by-step explanation:

According to the scenario it is a question of right angle triangle

To find the height of the plane above the ground we will use trigonometry identity.

here Ф = 15°

        opposite = height

        hypotenuse = 3000m

Plug values in the formula above

height = sin(15)(3000)

           = 776 .46 m

(make sure your calculator is in degree mode)

Answer:

776.46 m

Step-by-step explanation:

The angle of elevation is 15 degrees which is measured from the horizontal.

The height above the ground is the opposite side of the triangle, the hypotenuse is the 3000 m and the angle of elevation is 15 degrees.

The sine ratio is the one one that ties the relationship;

Therefore;

sin 15 = x/3000

x = sin 15 × 3000

   = 776.46 m

Answer:

The average speed of the car is [tex]s = 24\ mph[/tex]

Step-by-step explanation:

The average speed is defined as

[tex]s = \frac{d_1}{t}[/tex]

Where

s is the speed

d is the displacement made

t is the time it took to perform the displacement d.

On the first trip the speed was 20 mph and the displacement was 60 miles. Then we find the time [tex]t_1[/tex]

[tex]s = \frac{d}{t}[/tex]

[tex]t_1 = \frac{d_1}{s}\\\\t_1 = \frac{60}{20}\\\\t_1 = 3\ h[/tex]

On the second trip the speed was 30 mph and the distance traveled was the same: 60mph

We calculate [tex]t_2[/tex].

[tex]t_2 = \frac{60}{30}\\\\t_2 = 2\ h[/tex].

Now we can calculate the average speed for the entire route

[tex]s = \frac{d_1 + d_2}{t_1 + t_2}\\\\s = 60 +\frac{60}{3} +2\\\\s = \frac{120}{4}\\\\s = 24\ mph[/tex]

Answer:

Speed =  24 mph

Step-by-step explanation:

Distance traveled in the two way trip

2*(60 miles) = 120 miles

Time it took to arrive to the destination (first travel, 60 miles, 20mph)

Speed = distance/ time

t = distance/ speed = (60 miles) / (20 mph) = 3 hours

Time it took to come back (return travel, 60 miles, 30 mph)

t = (60 miles) / (30 mph) = 2 hours

Total time = (3 +2)  hours = 5 hours

So the average speed is

Speed = (120 miles) / (5 hours)  = 24 mph

The answer is 143312

Answer:

it is  143312                                    

Answer:

$78.00

Step-by-step explanation:

First, you would have to figure out how many tiles she would need. 3 inches is  equal to 6 feet according to the scale part, and then it would be 12 tiles because it is half a foot for the tiles. Then 3 1/2 would be 7 feet, and then 14 tiles. 12 plus 14 equals 26, and 26 times $3.00 is $78.00

Amy will pay $3.00 for the tiles for her bathroom floor.

A fraction represents a part of a whole.

The scale is 1/2 inch = 1 foot.

Length of bathroom = 3 inches × (1 foot / 24 inches)

= 1/8 feet

Width of bathroom = [tex]3\frac{1}{2}[/tex] inches(1 foot / 24 inches)

= 7/24 feet

We need to calculate the total area of the bathroom floor in square feet:

Area of bathroom floor = (length) x (width)

= (1/8 feet) x (7/24 feet)

= 7/192 square feet

Since each tile measures 1/2 foot on each side, the area of each tile is:

Area of one tile = (1/2 feet) x (1/2 feet) = 1/4 square feet

Total area of tiles needed = (area of bathroom floor) / (area of one tile)

= (7/192 square feet) / (1/4 square feet)

= 7/48 tiles

Amy will need to purchase 1 tile at a cost of $3.00 per tile, so the total cost of the tiles for her bathroom floor will be:

Total cost = (number of tiles) x (cost per tile)

= 1 tile x $3.00/tile = $3.00

Hence, Amy will pay $3.00 for the tiles for her bathroom floor.
