If angle 3 is a right angle, find angle 2
Answer:
∠2=37°
Step-by-step explanation:
Given:
∠1=4x°
∠2=∠4 (Vertical Angle Theorem)
∠3=90°
∠4=(3x+1)°
∠4=∠2 (Vertical Angle Theorem)
∠1+∠2+∠3=180° (We use this equation in the next step)
∠1+∠3+∠4=180°
Thus, ∠2=(3x+1)°, making:
(4x)°+(3x+1)°+90°=180°
7x+91=180
7x=89
x=12
This means:
∠1=4x=4(12)=48°
∠2=3x+1=3(12)+1=37°
∠3=90°
∠4=3x+1=3(12)+1=37°

Answer:
f(x) = 2,000(0.94)^x; 952 km^2
Step-by-step explanation:
Formula for exponential growth or decay:
f(x) = P(1 + r)^x
where
f(x) = future value in year x
P = present value
r = annual rate of growth (positive) or decrease (negative)
x = time in years
In this problem,
P = 2,000
r = -6% = -0.06; here r is negative since this is a decreasing function
The formula is
f(x) = 2,000(1 - 0.06)^x
f(x) = 2,000(0.94)^x
For year 12, x = 12.
f(x) = 2,000(0.94)^x
f(12) = 2,000(0.94)^12
f(12) = 952
All ratios equivalent to 24:12
Answer:

General form of a linear regression equation :
y = b1x + b0
b1 = slope ; b0 = intercept
Using an online regression calculator, the regression equation obtained is :
y = 5.8286 + 52.2286x
Comparing the equation ;
b1 = 52.23
b0 = 5.83

Step-by-step explanation:
A student's parents offer him one of two options to receive scholarship money for college.
Option A: Deposit $17,000.00 into his savings account and then add an additional $1,250.00 each day for 30 days
or
Option B: Deposit $0.50 into his savings account and then triple that amount each day for only 10 days
When rounded to the nearest cent, how much money is deposited into his savings account on the last day (day 30) for Option A, and how much is deposited into his savings account on the last day (day 10) for Option B? If the student keeps only what is deposited on the last day, which option should he choose?
Option A Versus Option B
Option A Option B
Day Amount Deposited Day Amount Deposited
0 $17,000.00 0 $0.50
1 $18,250.00 1 $1.50
2 $19,500.00 2 $4.50
A = $142,845.76, B = $29,524.50; B, because he receives $113,321.26 more
A = $54,500.00, B = $10.50; A, because he receives $54,489.50 more
A = $37,500.00, B = $59,049.00; B, because he receives $21,549.00 more
A = $54,500.00, B = $29,524.50; A, because he receives $24,975.50 more
Answer:
option a
Step-by-step explanation:
it is because $17,000.00 will make you have more money and have better things to do in the nearest future
The amount received by student in option A and B are A = $54,500.00, B = $29,524.50, Option A is better because student receives $24,975.50 more.
What is Simplification?Simplification in mathematical terms is a process to convert a long mathematical expression in simple and easy form.
(A)
Given that,
Amount deposit by student in starting = $17,000
Also, student add $1250 each day for 30 days,
Amount added in 30 days = 1250 x 30 = $37500
Total amount in account = 17000 + 37500 = 54500
The final amount in account is $54500.
(B)
Amount deposited into saving account = $0.50
Also, student triple that amount for 10 days,
Amount in account in 10 days = 0.50 x 3¹⁰ = 29524.5
Option A is a better deal because the student receives $24,975.50 more.
