i think the last question today lol

Answer:

Step-by-step explanation:

You cannot subtract JUST a denominator. The subtraction sign is lower down because of the odd printing just like the equal signs.

1. The first thing you have to do is change this from a mixed fraction into an improper fraction in order to subtract. This becomes:

2. This one requires you to multiply your denominator so that it is the same for both fractions. The least common denominator (LCD) for these fractions is 12

3. This is fairly straight-forward the denominators already match so just subtract the numerators

4. Because we have a full number we must make it into a fraction in order to subtract it and also turn the mixed fraction into an improper fraction

5. This problem requires multiple steps the first would be to make improper fractions then get a LCD and then of course subtract.

6. For this we will use another LCD.

It Jumps by six every number, so six would be my guess

Let 'x' be the distance from THE far bank   where 700 is the distance to the NEAR bank

boat one has travelled 700    (rate = 700/unit time)         boat two has travelled   x    rate = x / unit time

boat one then travels   x  + 400  more      and boat two travels   700 + (700+x -400) more    when they meet

The time is the same      rate x time = distance      distance/rate = time     equate the distances divided by the respective rates

(700 + x + 400)/700     =    (  x  +  700     +  (700+x-400) )/x

1100x + x^2 = 1400x + 700000

x^2-300x -700000 = 0                         quadratic formula yields  x = 1000  

One boat travels 700   the other   1000 whe they first meet.....width of river =   700+ 1000 = 1700 m

Step-by-step explanation:

24 / 12 = 2

Step-by-step explanation:

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of 0.

x+8x5+15x4+54x3-25x2-75x-34

Divide the highest order term in the dividend x5 by the highest order term in divisor x.

x4x+8x5+15x4+54x3-25x2-75x-34

Multiply the new quotient term by the divisor.

x4x+8x5+15x4+54x3-25x2-75x-34+x5+8x4

The expression needs to be subtracted from the dividend, so change all the signs in x5+8x4

x4x+8x5+15x4+54x3-25x2-75x-34-x5-8x4

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

x4x+8x5+15x4+54x3-25x2-75x-34-x5-8x4+7x4

Pull the next terms from the original dividend down into the current dividend.

x4x+8x5+15x4+54x3-25x2-75x-34-x5-8x4+7x4+54x3

Divide the highest order term in the dividend 7x4 by the highest order term in divisor x.

On dividing, x⁵+15x⁴+54x³−25x²−75x−34 by x+8, Quotient is x⁴+7x³−2x²−9x−3 and Remainder is -10.

An expression is a mathematical statement which consists of variables, constants and mathematical operators.

Dividend is x⁵+15x⁴+54x³−25x²−75x−34

Divisor is x+8

After division, the solution is attached in the image.

Quotient is ( x⁴+7x³−2x²−9x−3)

Remainder is -10

Answer:

should be 1/4 inches away from each side

Step-by-step explanation:

all I did was take the 10 inches,subtract 9.5 from that to get 1/2 left.

since it needs to be centered, divide that by two for each side.

and 1/2 ÷ 2 = 1/4

so I got 1/4 inches on each side.

Answer:

Step-by-step explanation:

see the figure below

As O is mid point of rectangle

distance between O to AB and DC is same

also distance between O to AD and BC is same

OP and OQ are perpendiculars so it is straight

and OP divides AB into equal segments as distance between O to AD and BC is same

same goes with OQ

Answer:

r = 15

Step-by-step explanation:

Using Pythagoras' identity in the right triangle OAB

with OM and OB the radii r of the circle

OA² = OB² + AB²

(r + 10)² = r² + 20² ← expand left side using FOIL

r² + 20r + 100 = r² + 400 ( subtract r² from both sides )

20r + 100 = 400 ( subtract 100 from both sides )

20r = 300 ( divide both sides by 20 )

r = 15

B is incorrect because:  2(-1) -3(-9)<9 which is 25<9 which is not true

Constant rates are used to illustrate linear functions.

(a) The average rate of change

This is calculated using:

[tex]\mathbf{Rate = \frac{y_2 -y_1}{x_2 -x_1}}[/tex]

So, we have:

[tex]\mathbf{Rate = \frac{31.5-22.50}{3.5 - 2.5}}[/tex]

[tex]\mathbf{Rate = \frac{9}{1.0}}[/tex]

[tex]\mathbf{Rate = 9.0}[/tex]

Hence, the average rate of change is $9.0 per hour

(b) A function that models the table of values

Let x represent hours, and y represent the earnings.

So, we have:

[tex]\mathbf{y =m (x - x_1) + y_1}[/tex]

Where:

m =Rate = 9.0

So, we have:

[tex]\mathbf{y = 9(x - 2.5) + 22.5}[/tex]

Expand

[tex]\mathbf{y = 9x - 22.5 + 22.5}[/tex]

[tex]\mathbf{y = 9x }[/tex]

Represent as a function

[tex]\mathbf{f(x) = 9x }[/tex]

Hence, the function that models the table is: [tex]\mathbf{f(x) = 9x }[/tex]

(c) Amount earned for 7.5 hours

This means that x = 7.5

So, we have:

[tex]\mathbf{f(7.5) = 9 \times 7.5 }[/tex]

[tex]\mathbf{f(7.5) = 67.5}[/tex]

Hence, the amount earned in 7.5 hours is $67.5

Answer:

velocity

Step-by-step explanation:

The velocity of the object is continually changing.  This velocity is the slope of the tangent line to the curve at a given point on the curve.

The corrected sentence is: When an object moves in a circle, the velocity of the object is continually changing.

Circular motion involves not only changes in the object's orientation or direction but also changes in its velocity.

Velocity includes both the speed of the object's movement and its direction. As an object moves around a circle, even if it maintains a constant speed, its velocity is changing because the direction in which it is moving is always changing.

This change in velocity is what allows the object to maintain its circular path rather than moving in a straight line.
