Of the three functions {f(x), g(x), h(x))} featured on the graph below (on the following page), rank the functions in order of greatest rate of growth to least.
9514 1404 393
Answer:
g, h, f
Step-by-step explanation:
A graph of two exponential curves will have the one with the least growth rate crossing under the one with the greater growth rate. Here, f(x) is shown crossing under g(x) and is on its way to a point of intersection with h(x). So, f(x) has the least growth rate.
g(x) and h(x) start out at about the same level, but g(x) curves upward faster, indicating it has the higher growth rate.
In order from greatest to least growth rate, the functions are ...
g(x), h(x), f(x)
Nicole took a taxi from her house to the airport. The taxi company charged a pick-up fee of $2.90 plus $1.75 per mile. The total fare was $44.90, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride.
Answer:
25.66 miles
Step-by-step explanation:
fee of $2.90 plus --> $2.90 + _______ = ______
total fare was $44.90--> ______ +______ = $44.90
$1.75 per mile,per mile would be x since the number of miles are unknown
$1.75 per mile --> ______ + $1.75x = ______
Put together: $2.90 + $1.75x = $44.90
Note: It could be written as '$1.75x + $2.90 = $44.90', it really doesn't matter
1. Subtract $2.90 from both sides : $1.75x + $2.90 - $2.90 = $44.90-$2.90 resulting in $1.75x = $44.90
2. Divide $1.75x form both sides: $1.75/$1.75x = $44.90/$1.75 resulting in x=25.66*rounded from 25.6571428571
x=25.66 miles

Equation of the secant line and tangent to a curve.
Let the function [tex]f(x)=2x^{2}+1[/tex] and its graph be:
(In both graphs (activity A and B) all the corresponding development must be carried out to arrive at the requested equation)
9514 1404 393
Answer:
A. y = -2x +13
B. y = 8x -7
Step-by-step explanation:
A. We can read the y-intercept of the secant line from the graph. It is 13.
The slope can also be read from the graph, but we choose to use the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (19 -9)/(-3 -2) = 10/-5 = -2
Then the slope-intercept formula for the line is ...
y = mx + b . . . . . . line of slope m and y-intercept b
y = -2x +13
__
B. The vertex of the given parabola is (0, 1). We notice that when x=1 (1 unit right of the vertex), y = 3 (2 units up from the vertex). This tells us the vertical scale factor of the parabola is 2. That means the vertex form equation is ...
y = a(x -h)^2 +k . . . . . . . . vertex (h, k), scale factor 'a'
y = 2(x-0)^2 +1 . . . . . . . use known values for (h, k)
y = 2x^2 +1
The derivative of this is ...
y' = 4x
So, at x=2, the given point A, the slope of the tangent line is ...
m = y' = 4(2) = 8
We have a point and the slope, so we can write the point-slope form of the equation for the tangent line:
y -9 = 8(x -2)
Rearranging to slope-intercept form, this is ...
y = 8x -7
__
Additional comment
You can also read the slope of the tangent line from the graph. The line also goes through the point (1, 1), so has a rise of 8 for a run of 1. The y-intercept can be found from ...
b = y -mx = 9 -8(2) = -7
This lets you write the equation of the tangent line directly from the graph.
That is, the parameters of both lines can be read from the graph, so there is very little "development" required.

A firm has a beta of 1.3 and a debt-to-equity ratio of .4. The market rate of return is 11.6
percent, the tax rate is 32 percent, and the risk-free rate is 3.3 percent. The pretax cost of debt
is 7.2 percent. What is the firm's WACC?
The WACC of the firm is 17.05%
The first step is to write out the parameters given in the question;
Beta= 1.3
Debt to equity ratio= 0.4
Market rate of return= 11.6%
= 11.6/100
= 0.116
Tax rate= 32%
= 32/100
= 0.32
Risk free rate= 3.3%
= 3.3/100
= 0.033
Pretax cost of debt= 7.2%
= 7.2/100
= 0.072
The firm's WACC can be calculated as follows
RS= 0.033+1.3(0.116-0.033)
= 0.033+1.3(0.083)
= 0.033+0.1079
= 0.1409
WACC= (1/1.4)(0.1409)+(2/1.4) (0.072)(1-0.32)
= (0.7142)(0.1409) + (1.4285)(0.072)(0.68)
= 0.1006+0.0699
= 0.1705(100)
= 17.05%
Hence the firm's WACC is 17.05%

Of the unskilled workers, six are foremen who earn sh 13500 per month each while the rest earn sh9000 per month .of the skilled workers. a half earn sh19500 each pm while the rest earn sh 24500 each per month .prepare one months wages bill for the firm
Answer:
3787000
Step-by-step explanation:
360*1/9=40 - skilled workers
360-40=320- the quantity of unskilled
6*13500=81000- wage for six unskilled
(320-6)*9000= 314*9000= 2826000- wage for the rest of unskilled
2826000+81000= 2907000- wage for unskilled
40/2=20 - the half on skilled
20*19500= 390000- Payment for a half
20*24500= 490000- Payment for ANOTHER HALF OF SKILLED WORKERS
2907000+390000+490000= 3787000

What is the measure of x?
Answer:
22
Step-by-step explanation:
This is a right angle so the sum of those would be equal to 90 degrees

4x + 2 = 90 subtract 2 from both sides
4x = 88 divide both sides by 4

the sum of 2 numbers is 18 and there difference is 6
Answer:
The two numbers are 6 and 12.
Step-by-step explanation:
So, let's start off, with x+y = 18 and x-y = 6.
Algebraically, we can add the above two equation sets, and we find out that 2x = 24, so x = 12. And then, it says the other number must be 6.
You start with a number that when added to the second number you will get 18 and when you subtract the second number from the first you will get 6. The difference between the above two results is 12.
So that difference of 12 is twice the second number; that means the second number is 6. And then using either of the given pieces of information, you can find that the first number is 12.
------------------------------------------------------
In conclusion:
6 + 12 = 18
12 - 18 = 6

In how many ways can someone order a meal consisting of one choice from each category?
There are 135 ways someone can order a meal consisting of one choice from each category.
Permutation and combinationTo find the total number of ways someone can order a meal consisting of one choice from each category, we need to multiply the number of options in each category:
Number of options for the main course = 5
Number of options for the side dish = 3
Number of options for the dessert = 3
Number of options for the beverage = 3
Using the multiplication principle, the total number of ways to order a meal is:
5 x 3 x 3 x 3 = 135
Therefore, there are 135 ways someone can order a meal consisting of one choice from each category.

opposite angles are equal
[tex]\\ \sf\longmapsto 13x+19=84[/tex]
[tex]\\ \sf\longmapsto 13x=84-19[/tex]
[tex]\\ \sf\longmapsto 13x=65[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{65}{13}[/tex]
[tex]\\ \sf\longmapsto x=5[/tex]
Answer:
[tex]\boxed {\boxed {\sf x=5}}[/tex]
Step-by-step explanation:
We are asked to solve for x.
We are given a pair of intersecting lines and 2 angles measuring (13x+19)° and 84°. The angles are opposite each other, so they are vertical angles. This means they are congruent or have the same angle measure.
Since the 2 angles are congruent, we can set them equal to each other.
[tex](13x+19)=84[/tex]
Solve for x by isolating the variable. This is done by performing inverse operations.
19 is being added to 13x. The inverse operation of addition is subtraction. Subtract 19 from both sides of the equation.
[tex]13x+19-19= 84 -19[/tex]
[tex]13x= 84 -19[/tex]
[tex]13x=65[/tex]
x is being multiplied by 13. The inverse operation of multiplication is division. Divide both sides by 13.
[tex]\frac {13x}{13}= \frac{65}{13}[/tex]
[tex]x= \frac{65}{13}[/tex]
[tex]x= 5[/tex]
For this pair of vertical angles, x is equal to 5.
