You are a financial advisor. You have a client who is 25 years old and has
$10,000 they want to invest into a retirement account. After investing
this money, the client will not be adding any money to the account. The
money will just let it grow until the client reaches age 65. As you are
helping them decide the best investment for their money, you discover the
following options:
-
Account A pays 7% annual interest, compounded quarterly
-
Account B pays 6.8% annual interest com[ounded monthly
-
Account c pays 7.1% annual interest, compounded yearly.
-
Account D ay 6.9% annual interest, compounded daily.
Since it’s your job to determine the best account for your clients money,
you have to figure out the future value of her money.
You know that the following formula calculates compound interest
Answer:
The first option is the best
Step-by-step explanation:
1 (1+ 07/4)^4 = 7.186 % annual
2 ( 1+.068/12)^12 = 7.0159 % annual
3 7.1 %
4 (1 + .069/365)^365 = 7.143

A rectangle has one side equal to (2x+4) cm and a perimeter of (6x+4) cm. What is the area of the rectangle in terms of x?
The area of the rectangle in terms of x is 2x² - 8
A rectangle is a quadrilateral with four right angles in the Euclidean plane.
A region's size on a flat or curved surface is expressed in terms of area, a unit of measurement. A surface region or plane area is the area of an open surface or the boundary of a three-dimensional object, whereas a plane region or area refers to the area of a form or planar lamina.A perimeter is a closed path that surrounds, encircles, or defines a length in one dimension or a shape in two dimensions.Given one side of the rectangle is 2x+4 and the perimeter is 6x+4
Let the other side be y.
We know that:
perimeter = 2 × (sum of two sides)
or, 6x + 4 = 2 (2x+4+y)
or,6x + 4 = 4x + 8 + 2y
or, 2x - 4 = 2 y
or, y = x - 2
Now area of the rectangle = product of sides = (x - 2)(2x+4)
Area = 2x² - 4x + 4x - 8
or, Area = 2x² - 8
Hence the area of the rectangle in terms of x is 2x² - 8

Assume z is a standard normal random variable. What is the value of z if the area between –z and z is 0.7580?
to the right is P(z> Z)
so P(z>Z) = 0.9909
P(z< Z) = 1- 0.9909 = 0.0091
Closest values from a z-table
P(z< -2.37) = 0.00889 (-0.00011 away)
p(z< -2.36) = 0.00914 (+0.00014 away)
so the answer must be (c) since it is between -2.36 and -2.37

PLS HELP Use the net to find the lateral area of the prism. 8 15 17 9
answer choices 473 440 275 352
The lateral area of the prism is the area of the three rectangles in the middle of the net. (The two triangles are the bases of the prism, which don't count toward lateral area.) The total length of the three rectangular prism faces is (8 +15 +17) cm = 40 cm. The width of those rectangles is 9 cm. The lateral area will be the product of this length and width:
... lateral area = (40 cm)(9 cm) = 360 cm²
Two gears are connected by a chain. The larger gear has a linear velocity of 17π/6 inches per second. The angular velocity of the smaller gear is 34π/3 radians per minute.

The radius of the smaller gear is 15 feet, Option C is correct.
What is Velocity?Velocity is defined as the rate of change of distance of a body with respect to time
We can use the relationship between linear velocity and angular velocity for gears to solve this problem:
v = rω
where v is the linear velocity, r is the radius of the gear, and ω is the angular velocity.
We are given the linear velocity of the larger gear, which is 17π/6 inches per second.
v = 17π/6 inches per second
ω = (34π/3) / 60 radians per second
the radius of the smaller gear is:
r = v / ω
= (17π/6) / ((34π/3) / 60)
= 17π/6×60/(34π/3)
=17π/6×60×3/34π
= 1/6 ×60× 3/2
= 180/12
=15 feet
Hence, the radius of the smaller gear is 15 feet.

What are the domain and range of y=-5/6(x+2)^2-8?
PLEASE HELP WILL MARK BRAINIST AND GIVE OUT FREE MORE POINTS IF YOU ARE CORRECT I DO CHECK IT PLEASE AND THANK YOU !!
Answer:
Domain: allrealnumbers
Range: f(x) <= -8
Step-by-step explanation:
This equation shows that this shape is a parabola that is opening downwards (because of the negative in the -5/6)
This means it has a highest point. The x+2 means the curve is shifted/slid/tranlated to the right 2 units and the -8 at the end shows that it is slid/shifted/translated down 8 units. So the curve only exists starting from -8 and going down. That is the range f(x) <= -8
All upward and downward opening parabolas have a domain of all real numbers.
Let's see
[tex]\\ \rm\rightarrowtail y=\dfrac{-5}{6}(x+2)^2-8[/tex]
[tex]\\ \rm\rightarrowtail x\in R[/tex]
As x lies on numerator for all real numbers its true and never gets undefinedDomain is R
Now
[tex]\\ \rm\rightarrowtail y=\dfrac{-5(x+2)^2}{6}-8[/tex]

Mrs.Watt traveled between two cities that were 750 km apart. On the return trip, she increased her average rate of travel by 20 km/hr and made the trip in 10 hours less time. Find her rate of travel in each direction.
Answer:
Let s = his speed on the outbound trip
Then s + 20 = his speed on the return trip
Let t = his travel time on the outbound trip
Then t - 10 = his travel time for the return trip
Given: d = 750
Since distance = speed x time, for the two trips we have
750 = s*t
750 = (s+20)(t-10)
Solve for t in the 1st equation, substitute in the 2nd:
750 = (s+20)(750/s-10)
Solve for s:
750 = 750 - 10s + 15000/s - 200
Simplify:
s^2 + 20s - 1500 = 0
Factor:
(s+50)(s-30) = 0
Take the positive solution, s = 30
So the rates are 30 kph and 50 kph
Samuel had 1 7/8 cups of milk. He used 1 5/8 cups of milk to make biscuts. What is the amount of milk, in cups , that samuel had after he made biscuts?
Answer:
1 7/8 - 1 5/8 = 2/8.
Step-by-step explanation:
The amount of milk in cups that Samuel had after he made biscuits is 1/4 cups.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Amount of milk Samuel had = 1 7/8 cups
Amount of milk used to make biscuits = 1 5/8 cups
We have to find the amount of milk left after he made the biscuits.
This is found by subtracting the total amount of milk by the amount of milk used to make the biscuits.
Amount of milk left = 1 7/8 - 1 5/8
= 2/8
= 1/4 cups
Hence 1/4 cups of milk will be left.
