The function that has a greater output value for x = 10 is table B
How to determine which function has a greater output value for x = 10?From the question, we have the following parameters that can be used in our computation:
The table of values
The table A is a linear function with
A(x) = 1 + 0.3x
The table B is an exponential function with the equation
B(x) = 1.3ˣ
When x = 10, we have
A(10) = 1 + 0.3 * 10 = 4
B(10) = 1.3¹⁰ = 13.79
13.79 is greater than 4
Hence, the function that has a greater output value for x = 10 is table B

From the point halfway between them, then angle of the elevation to the top of the trees is 36 and 52. how much taller is one tree than the other.
Answers
The height of the ramp above the ground is 1.55 meters.
The difference between the height of the tree is 33.20 meters
How to find sides of a right triangle?The situation forms a right angle triangle.
Therefore, the height the ramp above the ground can be calculated as follows:
Using Pythagoras theorem,
sin 15 = opposite / hypotenuse
sin 15 = x / 6
cross multiply
x = 6 sin 15
x = 6 × 0.2588190451
x = 1.55291427062
x = 1.55
Therefore, the height of the ramp above the ground is 1.55 meters
tan 36 = opposite / adjacent
tan 36 = x / 60
x = 60 tan 36
x = 43.5925516803
x = 43.60 meters
tan 52 = y / 60
60 tan 52 = y
y = 76.7964979316
y = 76.79 meters
The difference between the height of the tree = 76.79 - 43.60 = 33.20 meters

Answers
Answer:
y = 3x + 1
Step-by-step explanation:
The formula for equation of a line in slope intercept form is;
y = mx + c
Where;
m is slope
c is y-intercept
Now, since we have coordinates, we will get the equation as;
(y - y1)/(x - x1) = m
(y - 1)/(x - 0) = 3
y - 1 = 3x

oscar bought some markers notebooks and packs of sticky notes for his office he bought the same number of markers as notebooks he bought three more packs of sticky notes than markers and notebooks combined he paid $1.05 for each marker $2.25 for each notebook, and the packs for sticky notes were $1.95. how many of each kind of office supply did oscar buy if he paid $49.05 in all?
Answers
The number of each kind of office supply oscar bought is = markers= (43.2 - 4.2y)/3 notebooks = (43.2-3x)/4.2, sticky notes = [43.2 - 4.2y)/3 + (43.2-3x)/4.2] + 3.
Calculation of total office supplyThe number of markers he bought = X
The number of notebooks he bought= y
The number of sticky notes he bought= z= 3 + X+y
The amount he paid for markers = $1.05*X
The amount he paid for notebooks = $2.25*y
The amount he paid for sticky notes= $1.95 (3 + X+y)
The total amount he paid is = $49.05
That is;
$49.05 = $1.05x + $2.25y + $1.95 (3 + X+y)
$49.05 = $1.05x + $2.25y + $5.85 + $1.95x + $1.95y
$49.05 - $5.85 = 3x + 4.2y
$43.2 = 3x + 4.2y
Make X the subject of formula,
3x = 43.2 - 4.2y
X = (43.2 - 4.2y)/3
y= (43.2-3x)/4.2
z = [43.2 - 4.2y)/3 + (43.2-3x)/4.2] + 3

The amount to be invested annually to save $5,000 in 3 years, if the investment earns 5% annual interest, is $1,510.52.
How are annual payments or cash flows calculated?The annual payments represent the periodic cash outflows invested in accumulating a future value using an interest rate compounded for a period.
This can be achieved using the future value and present value formulas or factors.
We can also use an online finance calculator, as follows:
Data and Calculations:Future value = $5,000
Investment period = 3 years
Annual compound interest = 5%
N (# of periods) = 3 years
I/Y (Interest per year) = 5%
PV (Present Value) = $0
FV (Future Value) = $5,000 ($4,531.56 + $468.44)
Results:
PMT = $1,510.52
Sum of all periodic payments = $4,531.56 ($1,510.52 x 3_)
Total Interest = $468.44

Step-by-step explanation:
The absolute change is the difference between salaries now ands then.
12.30 - 5.85 = 6.45
The relative change in the percent increase.
percent increase = (new number - old number)/(old number) × 100%

A company’s 5-year bonds are yielding 7% per year. Treasury bonds with the same maturity are yielding 5.2% per year, and the real risk-free rate (r* ) is 2.75%. The average inflation premium is 2.05%, and the maturity risk premium is estimated to be 0.1 3 (t 2 1)%, where t 5 number of years to maturity. If the liquidity premium is 0.7%, what is the default risk premium on the corporate bonds
Answers
Based on the required rate of return, the real risk free rate, and the inflation premium, the default risk premium on the corporate bonds is 1.2%
How is the default risk premium found?The default risk premium can be found as:
=real risk free rate + Inflation premium + default risk premium + liquidity premium + maturity risk premium
Solving gives:
= 0.07 - 0.0275 - 0.0205 - (0.1 x (t - 1)%)
= 0.07 - 0.0275 - 0.0205 - (0.1 x (5 years - 1)%)
= 1.2%
The default risk premium refers to the return that the bond is offering over what a risk-free bond would offer.
This means that the corporate bond described is offering 1.2% more than what a risk-free government bond would offer.

The first job with a minimum completion time is Job E at Workstation B.
The second job with a minimum completion time after Job E is Job B at Workstation A.
The third job with a minimum completion time after Job B is Job D at Workstation B.
The fourth job with a minimum completion time after Job D is Job A at Workstation A.
The last job is Job C at Workstation B.
The sequence that minimizes total completion time is as follows:
B A C D E
A B
Calculation of Idle Time at Workstation B:Job Workstation A Workstation B Idle Time
