Step-by-step explanation:

Answer:

y = -1/2x +4

Step-by-step explanation:

First you need to get you're y-intercept form equation which is going to be : y = -1/2x + 7
How: x + 2y = 14
    -- Subtract x on both sides

x + 2y = 14

-x           -x

Then: 2y = -x +14
    -- Divide 2 on all parts
[tex]\frac{2y}{2} = -\frac{1x}{2} + \frac{14}{2}[/tex]

Equals: y = -1/2x + 7

Second find the slope which is : m = -1/2x

Third the formula for finding a parallel line to another is : y - y[tex]_{1}[/tex] = m(x - x[tex]_{1}[/tex])
The problem now would look like :
y - 0 = -1/2(x - -8)

   --Distribute the -1/2
y - 0 = -1/2x + 4
   --Add the 0 to 4
y = -1/2x +4

Answer:

A 36.

Step-by-step explanation:

If x is the number of boys then √x is the number of girls.

x + √x = 42

√x = 42 - x

Squaring both sides:

x = (42 - x)^2

1764 - 84x + x^2 - x = 0

x^2 - 85x + 1764 = 0

(x - 36)(x - 49) = 0

x =  number of boys = 49 or 36.

But the total number  = 42 so there must be 36 boys. Also √36 = 6 so the answer is 36 boys.

Answer:

The flow rate of dopamine per hour is 15 mg and the duration is 9.3 hours.

Step-by-step explanation:

It is given that A solution consisting of 70 mg of dopamine in 70 mL of solution is administered at a rate of 15 mL/hr.

A solution consisting of 182 mg of dopamine in 26 mL of solution is administered at a rate of 10 ​mL/hr.

Now, Let's calculate the flow rate of dopamine per hour;

=> Flow rate of dopamine per hour = (70 × 15)/70

=> Flow rate of dopamine per hour = 1050/70

=> Flow rate of dopamine per hour = 15 mg

Further, let's calculate how much the solution should last for a patient that is prescribed to receive 140 mg of dopamine;

=> Prescription = 140 mg

=> Flow rate of dopamine per hour = 15 mg

=> Duration = Prescription/Flow rate of dopamine per hour

=> Duration = 140/15

=> Duration = 9.3 hours

Therefore, the flow rate of dopamine per hour is 15 mg and the duration is 9.3 hours.

The equation in slope-intercept form describes a line that has a y-intercept of 4 and a slope of 3 will be y= 3x + 4.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, a line that has a y-intercept of 4 and a slope of 3.

The standard equation in the slope-intercept form is,

y = mx +c

Where m is the slope and c is the intercept. The ratio that y increase as x increases is the slope of a line.

Substitute the given value,

y = 3x + 4

Thus, the equation in slope-intercept form describes a line that has a y-intercept of 4 and a slope of 3 will be y= 3x + 4.

The percent error on Terry's reading is 8.3%

If there is something with a real measure of M, and you perform a measure that gives the value M', then the percent error on your measure is:

P = 100%*|M - M'|/M

In this case, the real measure is 36.0 and Terry's measure is 33.0 (I don't know the units, these are volumes).

So we have:

M = 36.0

M' = 33.0

Then we can use the formula for the percent error to get:

P = 100%*|36.0 - 33.0|/36.0 = 8.3%

We can see that the percent error in Terry's measure is 8.3%

A = 364 m²

Step-by-step explanation:

the figure is has 2 pairs of parallel sides and is therefore a parallelogram.

the area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

here b = 26 and h = 14 , then

A = 26 × 14 = 364 m²

y = 2 + 0.0357x shows the relationship between the height of the lemons and days, it will take 16 weeks for the lemon tree to reach 6ft.

Day 0 the plant is 2ft

Every 7 days the plants increase by 3 inches

Recall that, 1 inch = 0.0833 feet

Therfore  3 inches = 3 × 0.0833 = 0.2499ft

The plant increases in  by 0.2499/7 daily

0.25/7 = 0.0357

Let x be the days and the y be plant height, the plant height and the number of days can be related by

y = 2 + 0.0357x

Days (x)

b) when the tree will by 6ft, y = 6ft

      y = 2 + 0.0357x

      6 = 2 + 0.0357x

Collect like terms

6-2 = 0.037x

4 = 0.0357x

x = 4/0.0357

x = 112.04 days

x = 112 days

Answer:

The velocity of 13 feet per second into units is 3.9624 meter per second.

Step-by-step explanation:

It is given in the question that the velocity is 13 feet per second and we need to convert it into units.

Firstly, let us understand what is velocity;

When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.

Now, let us understand the concept of speed;

Speed, which is a scalar number, is the speed at which an item is moving. Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time. This is in contrast to an item travelling slowly, which travels a relatively little distance in the same length of time. Zero speed refers to an item that is not moving at all.

Furthermore, Speed is measured in meters per second. Exactly 3.6 kilometers per hour, or 2.237 miles per hour, equals one meter per second.

After convert the velocity of 13 feet per second into units we get;

=> 13 feet per second = 3.9624 meter per second

Therefore, the velocity of 13 feet per second into units is 3.9624 meter per second.

Length of segment 'cd' = 12 units

Given:-

'ol' is the mid-point of line segment 'cd'

'cl' = 13x + 8

'ld' = 23x - 4

We have to find the length of segment 'cd'.

Since the point 'ol' is the median to the segment cd then two expressions given 'cl' and 'ld' must add up to 'cd'.

'cd' = 'cl' + 'ld'

'cd' = (3x - 6) + (7x - 22)

'cd' = 10x - 28

- To determine the value of x we can also say that 'cl' and 'ld' must be equal because 'ol' is the common mid-point on the line segment 'cd'. So we can write:

'cl' = 'ld'

3x - 6 = 7x - 22

22  - 6 = 7x - 3x

       16 = 4x

        x = 4 units

- Now substitute the value of x in the expression developed for 'cd' as follows:

'cd' = 10x - 28

'cd' = 10 × 4 - 28

cd = 40 -28

'cd' = 12 units.

Therefore, the length of segment 'cd' is 12 units.

A reflection in mathematics is a mapping from such a Euclidean space to itself that is an isometry with just a hyperplane as a fixed point set; this set is known as the axis or plane of reflection. A figure's mirror image with in axis or plane or reflection is its image by reflection.

When a point is reflected across the x-axis, every x-coordinate remains unchanged, but the y-coordinate is assumed to represent the additive inverse. Point (x, reflection )'s from across x-axis is (x, -y).

When you reflect from across y-axis, the coordinates change as follows:

For the functions g (x) = 5 x - 2 and h (x) = x² + 1, the value of the composite function g o h (2)  will be 23.

We are given the functions:

g (x) = 5 x - 2

h (x) = x² + 1

We first need to find the composite function g o h (x).

So, we get that:

g o h (x) = g ( h (x) )

g o h (x) = 5 ( x² + 1 ) - 2

g o h (x) = 5 x ² + 5 - 2

g o h (x) = 5 x² + 3

Now, we need to find the value of the composite function for x = 2. So, we get that:

g o h (x = 2) = 5 (2)² + 3

g o h (2) = 5 (4) + 3

g o h (2) = 20 + 3

g o h (2) = 23
