which function increases faster?
function g
function f
they both increase at the same rate
Answers
The function, g(x), has a constant rate of change and will increase at a faster rate than the function f(x) for all the values of x.
Given:
g(x) = 5/2 x -3 ..... (1)
f(x) = - 3.5 at x = 0
So, putting the value of x=0 in equation (1) for comparison. We get,
g(x) at x = 0
=> g(x) = 5/2 x (0) - 3
=> g(x) = -3
In this value of x function g(x) is faster than function f(x) having a value equal to -3.5.
Similarly, put x = 1 in equation (1) for comparison. We get,
=> g(x) = 5/2 x (1) - 3
=> g(x) = (5-6)/2
=> g(x) = -1/2
In this value of x function g(x) is faster than function f(x) having a value equal to -1.
Similarly, put x = 2 in equation (1) for comparison. We get,
=> g(x) = 5/2 x (2) - 3
=> g(x) = (5-3)
=> g(x) = 2
In this value of x function g(x) is faster than function f(x) having a value equal to 1.5.
Similarly, put x = 3 in equation (1) for comparison. We get,
=> g(x) = 5/2 x (3) - 3
=> g(x) = (15/2 - 3)
=> g(x) = 7.5 - 3
=> g(x) = 4.5
In this value of x function g(x) is faster than function f(x) having a value equal to 4.
Therefore, for all values of x function g(x) is faster than function f(x).
function f(x).

What’s the unit rate for three dollars for 2 1/2 hours of work
Answers
The unit rate for three dollars for 2 1/2 hours of work will be $1.2 using the concept of unitary method.
What is unitary method?The unitary method is a technique that involves determining the value of a single unit and then calculating the value of the requisite number of units based on that value. The term unitary refers to a single or unique entity. As a result, the goal of this approach is to determine values in reference to a single unit. The unitary technique is a method for determining the value of any necessary quantity by first obtaining the value of the unit (one) quantity.
Here,
$3 for 2.5 hours of work,
1 hour will cost $x,
3/2.5=x/1
2.5x=3
x=$1.2
Using the unitary technique, the unit rate for three dollars for two and a half hours of labour will be $1.2.

Eric owns shares of a certain stock. If he sells off 8 shares each month for a year, find the change in the number of shares of stock he owns.
Answers
After solving the word problem, the change in the number of shares of stock he owns, is x-96.
In the given question we have to find the change in the number of shares of stock he owns.
As given that Eric owns shares of a certain stock. If he sells off 8 shares each month for a year.
Let Eric owns x shares of a certain stock.
If he sells off 8 shares each months for a year.
So as we know that in a year have 12 months.
In 1 month = 8 shares sells
12 months = 12×8 shares sells
12 months = 96 shares sells
So in a year Eric sells 96 shares and he have total x shares.
So the remaining shares are x-96.
Hence, the change in the number of shares of stock he owns, is x-96.

A certain insect can beat its wings 10 times per second. Write an equation in slope-intercept form that shows the relationship between flying time in seconds and the number of times the insect beats its wings.
Answers
The equation in slope-intercept form that shows the relationship is y = 10x
How to determine the equation?From the question, we have the following parameters that can be used in our computation:
Rate of beating wings = 10 times per second
The equation in slope-intercept form of the relationship is then represented as
y = Rate of beating wings * x
Where
y is the number of times
x is the wings
So, we have
y = 10 * x
Evaluate
y = 10x
Hence, the equation is y = 10x

4. The fourth figure posses the SAS property.
Given:
1. The first figure shows the SSS property.
Side-Side-Side criterion is referred to as the SSS criterion. According to this standard, two triangles are congruent if their respective triangles' three sides are equal to one another.
hence the two triangles are congruent.
2. The second figure posses the ASA property.
Angle-Side-Angle criterion is also known as ASA criterion. According to the ASA criterion, two triangles are congruent if any two of their included sides and related angles are equivalent in size to those of the other triangle.
hence the two triangles are congruent.
3. The third figure posses the hypotenuse length properety.
RHS criterion stands for right angle-hypotenuse-side congruence criterion. Under this criterion, two triangles are congruent, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle.
hence the two triangles are congruent.
4. The fourth figure posses the SAS property.
Side-Angle-Side criterion is referred to as the SAS criterion. According to this standard, two triangles are said to be congruent if their matching sides and included angles are the same on each side of each other.

Write the equation of the line that goes through point (-4, 1) and is perpendicular to the line 2y - 4x = -10. Write the equation in slope intercept form.
Answers
Answer:
y = 1/2x + 3
Step-by-step explanation:
first we change the first equation to slope-intercept form to find the reciprocal slope
2y - 4x = -10
add 4x to both sides
2y = 4x - 10
divide both sides by 2
y = 2x - 5
since perpendicular lines have reciprocal slopes the slope of our new line is 1/2
y = 1/2x + b
to find b we plug in the point
1 = 1/2(-4) + b
1 = -2 + b
add 2 to both sides
3 = b

Two approximations of the area of the region between the graph are
(9, 11)
Given;
To calculate two approximations of the area of the region between the graph of the function and the x-axis across the given interval, use the left and right endpoints and the specified number of rectangles. rectangles f(x) = 2x + 3, [0, 2], 4
The graph is positive and the width of each subinterval will be,
a = 0, b = 2, n = 4
Δx = b-a/n = 2-0/4
= 0.5
Now for different values;
x → f(x) = 2x+3
x₀ = 0 → f(x₀ ) = 2x+3 = 2(0)+3 = 3
x₁ = 0.5 → f(x₁) = 2x+3 = 2(0.5)+3 = 4
x₂ = 1.0 → f(x₂) = 2x2+3 = 2(1) +3 = 5
x₃ =1.5 → f(x₃) = 2x+3 = 2(1.5)+3 = 6
x₄ = 2 → f(x₄) = 2x+3 = 2(2)+3 = 7
The area by using the approximation using 4 approximating rectangles and right endpoints is given by,
A ≈ R₄ = ∑f(x) Δx = ( ƒ(x1)Δx + ƒ (x2)Δx+ ƒ (x3)Δx + ƒ (x4)Δx)
= 0.5 (4 + 5 + 6 + 7)
= 0.5 × 22
= 11
The area by using the approximation using 8 approximating rectangles and left endpoints is given by.
A ≈ L₄ = ∑f(x) Δx = ( ƒ(x0)Δx + ƒ (x1)Δx+ ƒ (x2)Δx + ƒ (x3)Δx)
= 0.5 (3 + 4 + 5 + 6)
= 0.5 × 18

Answers
Answer:
Step-by-step explanation:
Slope of a straight line is the gradient of that line.
Formula for gradient is rise over run. Meaning: m = (y2 - y1) / (x2 - x1)
To use this formula, you need 2 points of the straight line. They have already given you one: (8, -3). For the second one, we consider the equation of the line. The y-intercept is given too: -4.
Now, keep in mind, the y intercept is the point of the line that passes from x = 0. Meaning, the point where the line touches the y axis, and at y axis, x = 0. So our second point is (0, -4).
Now as we have 2 points, (8, -3) and (0, -4), we put the values in the formula: m = (y2 - y1) / (x2 - x1) = (-4 - (-3)) / (0 - 8) = -1 / -8 = 1 / 8

Answers
For a box given a sudden push up a ramp and the friction between the box and the ramp is not negligible, the diagrams which best represent the directions of the actual forces acting on the box as it moves upward after the push is Option A.
Friction refers to the force of resistance in the relative motion of solid surfaces in contact and sliding or rolling against each other. Frictional forces are affected by the surface texture and the amount of force impelling them together and the angle and position of the object. The actual forces acting on the box will be the normal force (always perpendicular to the surface), weight force (acting downward) and frictional force (acting opposite to the direction of push).
