The table below represents a linear function f(x) and the equation represents a function g(x): (See pic)
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer: The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 -12 0 -6 1 0 g(x) g(x) = 2x + 6 Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
PART B: y=mx +b is slope intercept form of linear equation where m=slope and b =y intercept
slope for line for function f(x) =-5-(-1) / -1-0 =-5+1/-1=-4/-1=4
y = 4x+b
3=4(1)+b
3=4+b
-1 =b
y=4x-1
f(x)=4x-1 slope = 4
g(x)=2x -7 slope = 2
b) y intercept for f(x) is -1
and g(x) is -7
so f(x) is having greater y intercept
In Problems 13 through 16, substitute y = e^rx into the given differential equation to determine all values of the constant r for which y = e^rx is a solution of the equation. 13. 3y' = 2y 14. 4y" = y 15. y" + y' - 2y = 0 16. 3y" + 3y' - 4y = 0
The values of given differential equation constant r are = 1/5 and -3.
A differential equation is an equation which contains one or more terms and the derivatives of one variable (i.e., dependent variable) with respect to the other variable (i.e., independent variable) dy/dx = f(x)
Here “x” is an independent variable and “y” is a dependent variable.
For example, dy/dx = 5x A differential equation contains derivatives which are either partial derivatives or ordinary derivatives.
The derivative represents a rate of change, and the differential equation describes a relationship between the quantity that is continuously varying with respect to the change in another quantity.
There are a lot of differential equations formulas to find the solution of the derivatives.
As y = e power rx
y¹= dy/dx= re power rx
and y'' = r²e power rx
Hence 5y'' +14y' – 3y = 0 can be written as
5r²e - 14re** - 3e¹² - 0
or 5r2 + 14r - 3 - 0
or 5r2 + 15r - r - 3 - 0
or (5r − 1)(r + 3) = 0
r=1/5 or r= -3

When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object
with mass 4 kg, the acceleration of the object is 9 m/s². When the same force acts upon another object, its acceleration is 6 m/s². What is the mass of this
object?
Step-by-step explanation:
a = k/m or ma = k
using 4 and 9 4* 9 = k = 36
then the equation becomes:
ma = 36
using a = 6
6 * m = 36 shows m = 6 kg
What is the measure of Angle X?
A. 80 Degrees
B. 100 Degrees
C. 110 Degrees
Answer:
Step-by-step explanation:
x + 80 = 180
x = 100
answer is B
Writing Task 1:
Which one of the following does not belong and why?
a) log(1/1000) = X
b) log1000 (10) = x
c) (10³) = x
d) log (1000) =X
log1000(10) = x does not belong. This is because it does not have a real solution, while the other options (a, c, and d) have valid solutions.
The correct answer is option B.
To determine which one of the given options does not belong, we need to evaluate each option and compare them based on their properties and mathematical relationships.
a) log(1/1000) = x
Using the logarithmic property that log(a) = -log(1/a), we can rewrite this equation as:
log(1/1000) = log(\(1000)^(^-^1^)\)
log(1/1000) = log(\(1000)^(^-^1^)\)) = -3
b) log1000(10) = x
This equation can be rewritten as:
log base 1000 (10) = x
Here, the logarithm is asking for the power to which 1000 should be raised to obtain 10. Since 10 is not a power of 1000, this equation does not have a real solution. Therefore, this option does not belong.
c) (10³) = x
This equation represents 10 raised to the power of 3, which is equal to 1000. Therefore, x = 1000.
d) log(1000) = x
Using the logarithmic property that log base 10\((10^x)\) = x, we can rewrite this equation as:
log(1000) = log\((10^3)\) = 3

Consider a tech company that wants to offer free breakfast to its employees if their confidence interval shows it will decrease the
proportion of employees who skip breakfast.
Each interval shows the difference in proportion of p₁ - P2 where p₁ represents the employees who skip breakfast when free
breakfast is offered and p2 represents the employees who skip breakfast when free breakfast is not offered. Determine if there is
enough evidence to suggest that offering free breakfast results in an increase in the proportion of employees who don't skip
breakfast.
(-0.44,-0.16)
Yes, we can be confident that employees will skip breakfast less when free breakfast is offered than when it's not.
Or
No, our confidence interval shows that there could be no difference in the proportion of employees who skip breakfast.
(-0.25, 0.05)
Yes, we can be confident that employees will skip breakfast less when free breakfast is offered than when it's not.
Or
No, our confidence interval shows that there could be no difference in the proportion of employees who skip breakfast.
(-0.23, 0.15)
Yes, we can be confident that employees will skip breakfast less when free breakfast is offered than when it's not.
Or
No, our confidence interval shows that there could be no difference in the proportion of employees who skip breakfast.
Answer:
Step-by-step explanation:
In this scenario, the confidence interval represents the possible range of differences in the proportion of employees who skip breakfast when free breakfast is offered and when it's not. A confidence interval that does not include zero indicates that there is statistically significant evidence to suggest a difference in proportions between these two groups.
Therefore, for the first interval (-0.44,-0.16), since it does not include zero, we can be confident that offering free breakfast results in a decrease in the proportion of employees who skip breakfast.
For the second interval (-0.25, 0.05), since it contains zero, we cannot be confident that there is a difference in the proportion of employees who skip breakfast between the two groups.
Similarly, for the third interval (-0.23, 0.15), since it contains zero, we cannot be confident that there is a difference in the proportion of employees who skip breakfast between the two groups.
So, the correct answer is:
For the interval (-0.44,-0.16), we can be confident that employees will skip breakfast less when free breakfast is offered than when it's not.
For the intervals (-0.25, 0.05) and (-0.23, 0.15), our confidence interval shows that there could be no difference in the proportion of employees who skip breakfast.

if a clock shows it is 3 o'clock, how could you describe the smaller angle made my the two hands of the clock? solve this problem any way you choose
The smaller angle made by the two hands of the clock at 3 o'clock is 90 degrees.
What is an angle?A figure known as an angle is created by two rays or line segments that meet at a place known as the vertex of the angle. The sides or legs of the angle are other names for the rays or line segments.
According to question:To determine the smaller angle made by the two hands of a clock when it is 3 o'clock, we can use the following formula:
angle = |(11/2) * m - 30h|
where:
m is the number of minutes past the hour (in this case, since it is 3 o'clock, m = 0)
h is the hour (in this case, h = 3)
By using this formula, we get:
angle = |(11/2) * 0 - 30(3)| = |0 - 90| = 90
Therefore, the smaller angle made by the two hands of the clock at 3 o'clock is 90 degrees.

Use the three functions shown. 1. f(x)=x² II. f(x)=√x III. f(x) = ln x For which of the functions, if any, is a trapezoidal approximation for the area under the curve y = f(x) over the interval [1, 4] with 3 equal subintervals less than the midpoint approximation? none of the functions O I only II and III only all of the functions
II and III only
We split up the integration interval [1, 4] into 3 equally-spaced subintervals of length (4 - 1)/3 = 1 :
[1, 2], [2, 3], [3, 4]
The area over each subinterval [L, R] is either approximated by a trapezoid, whose area will be
1 • (f(L) + f(R))/2
or by a rectangle with height f((L + R)/2) and hence area
1 • f((L + R)/2)
For f(x) = x², the area under f(x) over [1, 4] is approximated by
• using trapezoids (T) :
\(\displaystyle \int_1^4 x^2 \, dx \approx \frac{4-1}{2\times3} (1^2 + 2\times2^2 + 2\times3^2 + 4^2) = \frac{43}2 = \frac{86}4\)
• using midpoints (M) :
\(\displaystyle \int_1^4 x^2 \, dx \approx \frac{4-1}3 \left(\left(\frac32\right)^2 + \left(\frac52\right)^2 + \left(\frac72\right)^2\right) = \frac{83}4\)
so T > M. (This eliminates "I only" and "all of the functions".)
For f(x) = √x, the area is approximated by
• T :
\(\displaystyle \int_1^4 \sqrt x \, dx \approx \frac{4-1}{2\times3} (\sqrt1 + 2\sqrt2 + 2\sqrt3 + \sqrt4) \approx 4.646\)
• M :
\(\displaystyle \int_1^4 \sqrt x\, dx \approx \frac{4-1}3 \left(\sqrt{\frac32} + \sqrt{\frac52} + \sqrt{\frac72}\right) \approx 4.677\)
so T < M. (This eliminates "none of the functions".)
