$100 into a savings account that earns 6% annual intrest compounded monthly for 5 years
Answer:
$141.94
Step-by-step explanation:
Basically multiply 100 by .06, add the answer too 100. Which gets 106.
Multiply 106 by .06 and add the answer to 106, do that 5 times(which counts as the five years) and vuala, you got your answer.
And since it said an annual
interest, then the monthly compounding doesn't matter.
Lucy invested $19,000 in an account paying an interest rate of 3% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 8 years?

Which list shows the integers in order from lest to greatest ? -8 , -5 , 0 , 2 , 6 0 , 2 , -5 , 6 , -8 -5 , -8 , 0 , 2 , 6 0 , -8 , -5 , 2 , 6
Answer:
a.-8,-5,0,2,6
Step-by-step explanation:
We have to find the list which shows the integers in order from least to greatest.
We know that when we left side of zero on a number line then the values decrease and we go right side of zero then the value increases.
a.-8,-5,0,2,6
-8<-5<0<2<6
Hence, it is true.
b.0,2,-5,6,-8
-8 least and 6 is greatest
Therefore, it is false.
c.-5,-8,0,2,6
It is false.
d.0,-8,-5,2,6
It is false.
Option a is true,
Please can someone help me.
Answer:
4
Step-by-step explanation:
Answer:
y = 4[tex](2)^{x}[/tex]
Step-by-step explanation:
An exponential function in standard form is
y = a[tex]b^{x}[/tex]
Substitute points from the graph into the equation to find a and b
Using (0, 4 ), then
4 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ], so
a = 4
y = 4[tex]b^{x}[/tex]
Using (1, 8 ), then
8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = 2
y = 4 [tex](2)^{x}[/tex] ← exponential equation

Can someone explain why
(-5k^2m)(2km)^4(3km^4)^2
——————————————
k^2m^3
Simplifies to -720k^6m^10
But 3m/m^4 simplifies to 3/m^2
Even though their both fractions how come only one stays a fraction? What’s the difference so I can figure out in the future?
Answer:
1. [tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex] = -720[tex]k^{6}m^{10}[/tex]
2. [tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])
Step-by-step explanation:
1. The given expression is:
[tex]\frac{(-5k^{2}m)(2km)^{4} (3km^{4}) ^{2}}{k^{2}m^{3}}[/tex]
With respect to the principle of exponential, we have;
[tex]\frac{(-5k^{2}m)(2^{4}k^{4} m^{4})(3^{2}k^{2}m^{8})}{k^{2} m^{3} }[/tex] = [tex]\frac{(-5k^{2}m)(16k^{4} m^{4})(9k^{2}m^{8} }{k^{2}m^{3} }[/tex]
Applying the law of indices,
= [tex]\frac{(-5*16*9)(k^{2+4+2})(m^{1+4+8}) }{k^{2} m^{3} }[/tex]
= [tex]\frac{-720k^{8} m^{13} }{k^{2}m^{3} }[/tex]
= -720[tex]k^{8}m^{13}[/tex] x [tex]k^{-2} m^{-3}[/tex]
= -720[tex]k^{8-2} m^{13-3}[/tex]
= -720[tex]k^{6}m^{10}[/tex]
2. [tex]\frac{3m}{m^{4} }[/tex]
divide the numerator and denominator with common factor m,
= [tex]\frac{3}{m^{3} }[/tex]
This can not be simplified further since there are no more common factors, so that;
[tex]\frac{3m}{m^{4} }[/tex] = [tex]\frac{3}{m^{3} }[/tex] (or 3[tex]m^{-3}[/tex])

Joey is measuring the amount of time it takes for a frisbee to fly through the air he uses a stopwatch to time it and find that it takes 4.82 seconds if it actually takes 5.05 seconds then what is the percent error in Joey's measurement to the nearest 10th of a percent
Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%
Step-by-step explanation:
Step 1
Time as recorded by the stopwatch = 4.82 seconds
Real Time it takes for a Frisbee to fly through the air =5.05 seconds
percent error = Measured value – True Value /True value x 100.
= 4.82 - 5.05 / 5.05 x 100
=-0.23/5.05
=-0.0455 x 100
=4.5544%
Rounding to nearest 10th of a percent = - 4.6%

i need to find the slope from two points i don’t know how to do this!show work please
Answer:
2
Step-by-step explanation:
Ok, so they gave you these two points, since I can't actually graph it, then we can just make a table...
x y
4 6
6 10
From 6 to 10, you add 4 (this is for the y section)
From 4 to 6 you add 2 (this is for the x section)
Now you need to divide the y by the x....
y/x = 4/2 = 2
And 2 will be the answer for your slope, given these 2 points.
Hope this helped!
What does y stand for in math
Answer:
The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate. Also called "Ordinate"
Step-by-step explanation:
Answer:
In math a letter is always a variable. If you are solving an equation and the letter y is there you have to solve for y. So in math y stands for a variable.

Ace C.a.r.l.o.s.
what do i write i need help so i can do this
Answer:
Step-by-step explanation:
First what you want to is subtract 7 from both sides, then you want to divide -2/3 from both sides.
To isolate the variable you need to remove the terms from the side with the variable to remove the terms you need to do the same thing on both sides.
-2/3n + 7 = 15
First step is to subtract 7 from both sides to get:
-2/3n = 8
Now divide both sides by -2/3 to get:
N = 8 / -2/3
Then to solve for n simplify to get:
N = -12

Solve for x: -4x - 12 < 12
Seems like you are an imposter ;). This is Middle School math.
Anyways...
Answer:
x>6
Step-by-step explanation:
-4x-12<12
Add 12 on both sides.
-4x<24
Divide both sides by -4 to isolate x. Remember that if you are dividing by a negative, flip the sign!
x>6
