Terry was measuring the volume of water on a graduated cylinder but did not notice that the measurements incremented by 2 instead of by 1. As a result, he misread the volume of the liquid as 33.0 instead of 36.0. What is his percent error?
The percent error on Terry's reading is 8.3%
What is the percent error?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%

Let g(x)=5 x-2 and h(x)=x²+1 . Find the value of each expression. (g⁰ h)(2)
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
Therefore, 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.

If the expression is [tex]log_{b}[/tex](b/x), then the expanded form of the expression looks like [tex]log_{b}b-log_{b}x[/tex].
Given that the expression is [tex]log_{b}[/tex](b/x).
We are required to find the expanded form of the expression.
The change of base formula is basically used to re-write a logarithm operation as a fraction of logarithms with a new base.
We know that log (m/n)= log m- log n.

What exactly is the meaning of reflection?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.
Briefing: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:

number of boys and girls playing in the park is 42, find the number of boys.
A. 36
OB.
49
OC. 7
OD. 6
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.

A solution consisting of 70 mg of dopamine in 70 mL of solution is administered at a rate of 15 mL/hr. Complete parts (a) and (b)
below.
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.

x+2y=14?
Answer: The question is not clear.
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

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

Segment ol is a median to the segment cd. cl is =3x-6. ld is =7x-22. find the length of segment cd hi
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.

Your velocity is 13 feet per second. What's your speed in units?
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.
