Answer:

36 - 1/2x = 0

72 minutes

Step-by-step explanation:

there is a total of 3 feet in the pool at the start, 1 ft = 12 in, and 3 ft = 36 in. the pool is losing water, so we have to subtract. it is losing water at a rate of -1/2 in per minute, and we don't know how many minutes it will take

we have to set it equal to 0 because we are trying to find out how long it will be until the pool is completely drained, which is when there will be no water left, so it will be 0

subtract 36 from both sides

-1/2x = -36

divide both sides by -1/2

x = 72

72 minutes

Answer:b = (2A - hB)/h

Step-by-step explanation:

See , we know area of a trapezoid is equal to 1/2*(sum of parallel sides)* perpendicular distance between parallel sides.

Here B and b are parallel sides which we know by comparing the equation.

And 'h' here is the perpendicular distance between parallel sides.

We have to write the equation in terms of one of the parallel sides 'b'

Our formula is A = 1/2*h*(B+b)

I.e. 2A = h*(B+b) (Multiplying both sides by 2)

I.e. 2A - hB = hb

I.e. b = (2A - hB)/h

Answer:

y = 2(m + 1/2)^ -25/2

Step-by-step explanation:

vertex form is:

y = 2m^2 + 2m - 12

y + 12 + ( )___ =( ) 2m^2 + 2m + ___

Because a is not one, you must divide the entire right side by the a value, which is 2. Then place the 2 in the parenthesis.

y + 12 + (2)__ = (2) m^2 + m + __

Take half of b, b being one.

Half of be is 1/2. Now square it to get 1/4. Place that value in the blanks.

y + 12 + (2)1/4 = (2) m^2 + m + 1/4

Now simplify the left side and factor the right side.

y+ 12 + 1/2 = 2(m + 1/2)^2

y + 25/2 = 2(m + 1/2)^2

Subtract 25/2 from both sides.

y = 2(m + 1/2)^ -25/2

The 20th term of the given arithmetic sequence 8, 21, 34, 47, 60... is 255.

In the field of mathematics, this type of problem is referred to as an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. This difference is called the common difference.

In your question, the arithmetic sequence provided is 8, 21, 34, 47, 60... Here, the common difference is 13 (i.e., every term after the first is 13 more than the preceding term).

To find any term (let's say the nth term) in an arithmetic sequence, you can use the formula:

nth term = first term + (n - 1) * common difference

Applying this formula to find the 20th term:

20th term = 8 + (20 - 1) * 13 = 8 + 247 = 255

To find the length of Rajesh's shoe, convert the additional length from millimeters to centimeters and add it to Pinky's shoe length. Rajesh's shoe is 21.1 cm long.

The subject of this question is Mathematics and it is suitable for a Middle School student. To find the length of Rajesh's shoe, we need to add the length of Pinky's shoe to the additional length that Rajesh's shoe has. Pinky's shoe is 20.4 cm long, and Rajesh's shoe is 7 mm longer.

Firstly, we need to convert millimeters to centimeters since 1 cm equals 10 mm. Therefore, 7 mm is equivalent to 0.7 cm (since 7 divided by 10 equals 0.7).

Next, we add this length to Pinky's shoe length:

Rajesh's shoe length equals 21.1 cm.

  q = 10

Step-by-step explanation:

The desired form is a rearrangement of the given equation, divided by the leading coefficient.

A monic polynomial is one with a leading coefficient of 1. The desired form requires that we start from that condition. In order to avoid fractions, we can begin by subtracting the constant term on the left.

  2x^2 -20x +49 = 19 . . . . . . given

  2x^2 -20x = -30 . . . . . . . . subtract 49

The square of the binomial a+b is given by ...

  (x +b)^2 = x^2 +2bx +b^2

That is the constant term on the right is the square of half the coefficient of x. To achieve this perfect square trinomial in our equation, we need to add the square of half of -10.

The temperature at the mountain base camp dropped from -5 degrees Celsius on Wednesday to -7 degrees Celsius Thursday morning, and finally to -8 degrees Celsius on Thursday evening.

To solve this, we first have to know the temperature on Wednesday, which is −5 degrees Celsius. On Thursday morning, the temperature was 2 degrees Celsius lower than Wednesday, so we subtract 2 from -5 which gives us -7 degrees Celsius. By Thursday evening, the temperature had dropped another 1 degree Celsius, so we subtract 1 from -7, resulting in a base camp temperature of -8 degrees Celsius.

Answer:

Step-by-step explanation:

Given that two lines are perpendicular.

Slope of green line (one of the lines) is -3.  

To find the slope of other perpendicular line red.

We know that angle between two lines with slopes m1 and m2 would be

[tex]tan^{-1} \frac{m1-m2}{1+m1m2}[/tex]

where m1 is the slope of I line and m2 slope of second line.

Here since two lines are perpendicular angle between them is 90 degrees and hence we get infinity as tan x

this implies denominator for [tex] \frac{m1-m2}{1+m1m2}[/tex]=0

i.e. 1+m1m2 = 0

Or m1m2 =-1

Since one of slope m1 = -3 we have

-3m2= (-1) or m2 = 1/3

Answer:

Step-by-step explanation:

If you know what g(x) looks like, you can find f(x). Every y point of g(x) is f(x) + 6.

The general point of g(x) is (x,f(x) + 6). That is the major difference. Just so you can see it visually, the both graphs are shown below.

red: f(x) = x^2

blue: f(x) = f(x) + 6 = x^2 + 6

green: x = 2  With the two points shown that intercept the two given functions.

Purple(?): x = - 2 with the two points shown that intercept the two given functions.

The graphs of both g(x) =x² +6 and f(x)=x² are parabolas. However, while the vertex of the graph of f(x) = x^2 is at the origin, the graph of g(x) = x² + 6 is shifted upwards by six units, with the vertex of g(x) at (0,6). The shape of the two graphs is identical.

The graphs of g(x) =x² +6 and f(x)=x² are both parabolas, but their positions differ on the coordinate plane. The function f(x) = x² is a standard quadratic function with a vertex at the origin (0,0). On the other hand, g(x) = x² + 6 is a vertical translation of the graph of f(x) = x2 upwards by six units. So, the vertex of g(x) is at the position (0, 6). Furthermore, the shape of the two graphs will remain the same as they both have the same degree and leading coefficient.
