From the figure, we can see that

Line CE is perpendicular to line AB

This means that

HEB + CEH = 90 degrees ---- complementary angles

HEB + AEH = 180 degrees ---- supplementary angles

A patient is to receive 0.25 mg of Medication A per kg of body weight per day. If the patient is a 157 lb man, how much medication A will he need?

Answers

The patient needs 17.66 mg of medication A .

Unitary method is "A way of finding a single-unit value from a multi-unit value, and then finding a multi-unit value from a single-unit value."For simplicity, always write what you calculate on the right and what you know on the left.In order to do that, we must first find the value of one thing by division and then find the value of more or fewer things by multiplication.

It is given that a patient has weight 157 lbs.

We apply division because we need to find the cost of one item given the  cost of many items. If you need to find the cost of many items from the cost of one item,  apply the multiplication operation.

We need to convert this weight in kilogram using unitary method , we get      1 pound have = 0.45 kilogram

           157 pound will have [tex]=157\times0.45[/tex]

                                              [tex]=70.65[/tex] kilogram

A patient receive 0.25 mg of Medication A per kg

Using unitary method , we get

  1 kg of body receives = 0.25 mg of medication A

  70.65 kg of body receives [tex]=0.25\times 70.65[/tex]

                                                [tex]=17.66[/tex] mg of medication A

What is the equation of the linear function in slope-intercept form described by this table?

Answers

The equation of line in slope intercept form described from given table will be equal to y = -2x + 1

What is the slope intercept form of a line ?

The equation of a line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

From the given figure we can find out that the points are (x1.y1) = (-2 , 5) and (x2 , y2) = ( -1 , 3).

The equation of line in slope intercept form

y = mx + c

Where m is the slope, and c is the y-intercept.

We have points (-2, 5) and (-1,3). Thus , the slope (m) will be :

m = ( [tex]y_{2} - y_{1}[/tex] ) /( [tex]x_{2} - x_{1}[/tex] )

m = ( 3 - 5 ) / ( -1 + 2)

m = -2

Using this value to find out the equation of line we get :

y = -2x + c

Point (-2,5) means that when x = -2 then y = 5 , and we use this data to find value of c , which is the y- intercept ;

5 = -2 × -2 + c

c = 5 - 4

c = 1

So , in slope intercept form the equation of line will be ;

y = -2x + 1

Therefore , the equation of line in slope intercept form will be y = -2x + 1.

A sequence is defined recursively using the formula f(n+1)=-0.5f(n). If the first term of the sequence is 120, what is f(5)

Answers

Answer:

The sequence's fifth term is equal to 7.5.

Step-by-step explanation:

It is given in the question that A sequence is defined recursively using the formula f(n+1)=-0.5f(n) and we need to calculate f(5) if the first term of the sequence is 120.

Firstly,

The definition of a series is given by the formula f (n + 1) = -0.5 f. (n).

Now, what will be f(5) if the sequence's initial term is 120, let's calculate;

Recursively, a series is defined as follows;

=> f(n) = 120 if n = 1, otherwise.

Otherwise,

=> f(n) =-0.5f(n-1) if n > 1.

Now,

=> f(1) = 120

=> f(2) = -0.5f(1) = -0.5(120) = -60

=> f(3) = -0.5f(2) = -0.5(-60) = 30

=> f(4) = -0.5f(3) = -0.5(30) = -15

=> f(5) = -0.5f(4) = -0.5(-15) = 7.5

So, For n > 1, f(n) = (-0.5)(n-1) × 120

Therefore, the sequence's fifth term is equal to 7.5.

2b) x < - 3

2e) x < 3 or x < -3

Step-by-step explanation:

Format for quadratic equations (the only difference in quadratic equations is that the equal sign is replaced with any of the inequality symbols (< , > , ≥ , and ≤)

ax² + bx + c = 0

- To factor quadratic inequalities (we're using 2b) as a demonstration)

1) Find two numbers that make the product equal to a×c (1×9) which is 9 and the sum that equals to b which is 6. Those two numbers in this case is positive 3 and positive 3

2) Spilt the middle term with those two numbers which are positive 3 and positive 3 so the inequality x² + 6x + 9 is going to become x² + 3x + 3x + 9

3) Take the common terms and simplify the common terms in this case the common terms are x and + 3 so it can be factored as (x + 3) and (x + 3)

To find each x make each term greater than 0 so it would be x + 3 < 0 and x + 3 < 0

4) Solve for x (it is the same way to solve x in inequalities as it were for equations which is doing inverse operations to order to islolate x) It would be x + 3 - 3 < 0 - 3 which is x < - 3

2e)

1) You essentially do the same steps for solving this question too but a shortcut way of doing factoring is to do the perfect square method which is to look a c which is 9 and if its a perfect squares you can factor it as (x+3) and (x-3) since not only is the 9 negative both of these terms when added cancel out each other.

2)To find x make everything < 0 so it would be x + 3 < 0 and x - 3 < 0

3) Solve for x it would be x + 3 - 3 < 0 - 3 and x - 3 + 3 < 0 + 3 . The roots are x < - 3 or x < 3

What is slope intercept form of line?

The slope intercept form of a line is y=mx+c, where m is the slope of line.

  slope = (110 -80)/(200 -10) = 30/200 = 0.15

The first entry in the table shows the y-intercept, the value of earnings (80) for zero sales. The slope-intercept form of the equation for a line is

  y = slope*x + y-intercept

To answer the first question, we put the slope and intercept values in the appropriate spots in the equation.

A cargo truck is traveling 70 miles per hour and plans to travel 840 miles, plus or minus 105 miles, depending on fuel levels. Fnd the minimum and maximum number of hours the truck will travel at that speed.
The minimum is 10.5 hours and the maximum is not 12.2 hours.​

Answers

The minimum and a maximum number of hours the truck will travel at that speed are 10.5 and 13.5 hours respectively.

What is velocity?

Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.

Average velocity = total distance / total time taken

Units of velocity are given by ⇒ meter/second

Speed of truck = 70 miles/hour

Maximum distance = 840 + 105 = 945 miles.

Minimum distance = 840 - 105 = 735 miles.

Now,

Time = distance / velocity

Minimum time = minimum distance / velocity

So,

Minimum time = 735 / 70 = 10.5 hour.

Maximum time = maximum distance / velocity.

Maximum time = 945 / 70 = 13.5 hour.

Hence "The minimum and a maximum number of hours the truck will travel at that speed are 10.5 and 13.5 hours respectively".

Answers

The cost of the wool insulation required for the loft floor is £149.16498

How to estimate the cost of the wool insulation required for the loft floor?

The given parameters are

Roll of wool = 114 cm by 5.2 m

One roll = £19.65 per roll

The area of one roll is calculated as

Area = Length * Width

So, we have

Area = 114 cm x 5.2 m

Convert cm to m

Area = 1.14 m x 5.2 m

Evaluate the product

Area = 5.928 m^2

The cost of the required area of loft floor is

Total cost = Unit cost/Area of 1 roll x Area of floor

This gives

Total cost = £19.65/5.928 * 4.5 * 10

Total cost = £149.16498
