Answer:
The number of years needed is 15.75 years.
Step-by-step explanation:
The investment amount (present value) = $200
Interest rate =4.5%
Double of investment = $400
Now we have to find the time or number of years in which the investment amount will be doubled. So, just use the below formula to find the number of years.
Future value = present value ×(1+interest rate)^n
400 = 200×(1+4.5%)^n
N = 15.75 years
The number of years required to double the amount is 15.75 years.

Determine whether the equation defines y as a function of x.
x+y=9 and x^2+y^2=1 and x=y^2
Answer:
Function: [tex]x+y=9[/tex]
Not Function: [tex]x^2+y^2=1[/tex] and [tex]x=y^2[/tex]
Step-by-step explanation:
Given
[tex]x+y=9[/tex]
[tex]x^2+y^2=1[/tex]
[tex]x=y^2[/tex]
Required
Determine if [tex]y[/tex] is a function of [tex]x[/tex]
Solving x+y=9
[tex]x+y=9[/tex]
Make y the subject of formula
[tex]y = 9 - x[/tex]
Hence; y is a function of x
Solving [tex]x^2+y^2=1[/tex]
[tex]x^2+y^2=1[/tex]
Subtract x² from both sides
[tex]y^2=1 - x^2[/tex]
Square root of both sides
[tex]y =\± \sqrt{1 - x^2}[/tex]
This implies that
[tex]y =\sqrt{1 - x^2}[/tex] or [tex]y =-\sqrt{1 - x^2}[/tex]
Because [tex]y[/tex] can be any of those two expressions, it is not a function.
Solving [tex]x=y^2[/tex]
[tex]x=y^2[/tex]
Reorder
[tex]y^2 = x[/tex]
Take square roots
[tex]y = \±\sqrt{x}[/tex]
This implies that
[tex]y = \sqrt{x}[/tex] or [tex]y = -\sqrt{x}[/tex]
Because [tex]y[/tex] can be any of those two expressions, it is not a function.

The length of a rectangle is 6 meters more than three times the width. The perimeter of the rectangle is 44 meters. What are the dimensions of the rectangle?
Answer:
width=4
length=18
Step-by-step explanation:
length-6=3width
length=3width+6
also:
perimeter of the rectangle=2(length+width)
44/2=width+length
22=width+length
now put the length we found in the 1st equation, in 22=width+length
=>22=width+3width+6
22-6=4width
width=4
now do the exact same thing with one of these equations:
22=width+length
length=3width+6
I'd do it with the 1st one:
22=4+length
22-4= length
length=18

Answer:
1). Option (C)
2). Option (A). degree of 3 = 0
Step-by-step explanation:
A polynomial having one term is called 'Monomial' in algebraic terms.
3 is a number that is a polynomial with a single term.
Therefore, the given expression is a polynomial.
Hence Option (C) is the answer.
3 can be written as 3x⁰ (Since x⁰ = 1)
Therefore, degree of the polynomial is 0.
Option (A). degree of the polynomial = 0
a windshield wiper blade is 17 in Long. Calculate the area come by the blade as it rotates through an angle of 138 degrees.
Answer: 348 in²
Step-by-step explanation:
Area of a circle is πr². Area of a sector is the same formula but only for the section so you need to determine what fraction of the circle it is. You do this by dividing by 360° if degrees are provided or by 2π if radians are given.
[tex]A=\pi r^2 \bigg(\dfrac{\theta}{360^o}\bigg)[/tex]
Given: r = 17
Ф = 138°
[tex]A=\pi(17)^2\bigg(\dfrac{138^o}{360^o}\bigg)\\\\\\.\quad =289\pi \bigg(\dfrac{23}{60}\bigg)\\\\\\.\quad =\dfrac{6647\pi}{60}\pi\\\\\\.\quad =347.9\ in^2[/tex]

How does the area of the scale drawing where 1 centimeter represents 10 miles compare to the area of a the drawing where 1 centimeter represents 30 miles? Area if 1 cm= 10 mi: square miles Area if 1 cm = 30 mi: square miles The area would be times as great.
Answer:
100 square miles900 square miles9 times as greatStep-by-step explanation:
It seems rather obvious that ...
(1 cm)^2 ⇒ (10 mi)^2 = 100 mi^2 . . . on the first drawing
(1 cm)^2 ⇒ (30 mi)^2 = 900 mi^2 . . . on the second drawing
The area on the second drawing is 900/100 = 9 times as great.
_____
These are the areas represented by 1 square cm on the scale drawing. If the drawing is larger, then the represented area is correspondingly larger. The ratio of represented areas is still 9 times for drawings of the same size.
Dimensional analysis. How many years of your life will you be sleep if you live 3.95 x 10^7 minutes and average 8 hours sleep/night.
Answer:
The total years of sleep = 25.05 years
Step-by-step explanation:
Given total time in minutes = 3.95 x 10^7
Now convert the total time in hours = (3.95 x 10^7) / 60 = 658333.333 hours
Now covert the total hours into the day. Since a day has 24 hours so divide the total hours by 24 = 658333.333 / 24 = 27430.5555 days.
A person sleeps 8 hours a day, so total hours of sleep = 8 × a number of days.
A person sleeps 8 hours a day, so total hours of sleep = 8 × 27430.5555 days.
Thus, total sleeping hours = 219444.444
Now convert it into a number of years.
Convert total hours into the day and then years.
Number of days = 219444.444 / 24 = 9143.5185 days.
Now covert the total days in to years = 9143.5185 / 365 = 25.05 years

6.545, since it is the midpoint of 6.54 and 6.55.
Hopefully it helps!
Please mark brainliest :)
The mid - point between the numbers is 6.545.
We have two decimal numbers → 6.54 and 6.55
We have to determine their mid - point.
You have two numbers - 'x' and 'y'. Find the mid - point between these two numbers.The midpoint (n) between these two numbers will be -
[tex]$n=\frac{x+y}{2}[/tex]
According to the question, we have -
Number 1 → 6.54
Number 2 → 6.55
Assume the mid - point be n. Therefore -
n = [tex]\frac{6.54+6.55}{2}[/tex] = 6.545
Hence, the mid - point between the numbers is 6.545.

What is the answer for 10-6(5-2y)
Answer:
-20 + 12y
Step-by-step explanation:
Equation: 10 - 6(5 - 2y)
Step 1:
10 - 30 + 12y Multiply (5 - 2y) by -6 (distributive property)
Step 2:
-20 + 12y Subtract 10 by 30 (10 - 30 = -20)
Answer:
[tex]12y-20[/tex]
Step-by-step explanation:
First, we need to distribute.
[tex]= 10+(-6)(5)+(-6)(-2y)= 10+-30+12y[/tex]
