Answer:
£6956.52
Step-by-step explanation:
Given data
R=5%
A= £8000
T= 3 years
P=???
The compound interest is
A=P(1+r)^t
8000= P(1+0.05)^3
8000= P(1.05)^3
8000= P1.15
P= 8000/1.15
P=6956.52
Hence she needs to invest £6956.52

(x+3)(x-1)
where are the zeros in this function?
Answer:
x=-3,1
Step-by-step explanation:
The roots (zeros) are the
x
values where the graph intersects the x-axis. To find the roots (zeros), replace
y
with
0
and solve for
x
.

What is the solution of the following system? Use the substitution method.
y – 2x = 8
16 + 4x = 2y
O The only solution is (24, 0).
O The only solution is (1, 10).
○There is no solution.
O There are an infinite number of solutions.
Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

step 1 is wrong . The 1st step should be 15² - 9² = c² .
Answer: step A
Step-by-step explanation:
The Pythagorean theorem is a^2+b^2=c^2, where c is always the hypotenuse (the longest side of the triangle). Step A is written as 9^2(thats the a value squared)+15^2(which is the hypotenuse value squared)=c^2. It should be: 9^2+b^2=15^2

Hey eveyone. Im 7th grade 13 years old. Whenever i am at school i always think people think i smell bad. I dont know if its true. I put deoderant on take a shower and EVERYTHING. I dont wanna smell bad. It might just be in my head. Plz respond.
Answer:Researchers say a psychiatric condition characterized by a person's mistaken belief that he or she smells bad is vastly under-recognized. Called olfactory reference syndrome, the condition is "probably very common," says Katharine Phillips, MD, of Rhode Island Hospital in Providence. so you might just be thinking thst in your head man. just shower, brush teeth etc... or this could be a possibility...What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.
Step-by-step explanation:
A box is made of wood with its external dimensions of 154 cm x 100 cm x 84 cm and thickness of 2 cm.
How much wood was used to make it?
Answer:
Step-by-step explanation:
volume of 154×100×84 box = 1,293,600 cm³
dimensions of airspace = (154-4) by (100-4) by (84-4) = 150 by 96 by 80
volume of airspace = 150×96×80 = 1,152,000 cm³
volume of wood used = 1,293,600 - 1,152,000 = 141,600 cm³

Write and expression for the calculation add 9 to the product of 4 and 5
Answer:
5×4+9
Step-by-step explanation:
The product of something means to multiply, so you would multiply 5 and 4 together.
Then you would add 9 to that.
arrange the variables so that they are on the same sides: -5w - 9 = 3w + 7
Answer:
-8w=16
Step-by-step explanation:
-5w-9+9 = 3w+7+9
-5w=3w+16
-5w-3w=3w-3w+16
-8w=16
To solve:
-8w/-8=16/-8
w = -2
What is the slope of the line shown above?
3x – 3y = -9
4x + 4y= 12
show me the steps for substitution?
Answer:
y=3 and x=0
Step-by-step explanation:
3x−3y=−9. i'm going to solve for x.
3x−3y+3y=−9+3y
3x=3y−9
3x/3=(3y-9)/3 to isolate x we have to divide everything by 3
x=y−3
so now that we have x we can substitute it in 4x+4y=12
4(y-3)+4y=12
4y-12+4y=12
8y-12=12
8y-12+12=12+12
8y=24
8y/8=24/8
y=3
we have y which equals 3, so now we can substitute it into any equation so solve for x again.
3x – 3y = -9
3x-3(3)=-9
3x-9=-9
3x-9+9=-9+9
3x=0
3x/3=0/3
x=0
so, final answers are y=3 and x=0
checking our work:
3(0)-3(3)=-9
0-9=-9
-9=-9 true
4(0)+4(3)=12
0+12=12
12=12 true

This is a summation notation also called the sigma notation.
In this case it means starting with k=0 what's the sum of (1+k!) for all integer k until 4
So we just need to find the sum 1+0!+1+1!+1+2!+1+3!+1+4!=5+1+2+6+24=8+30=38
at the brechin castle sugar factory, the normal working week is 40 hours, during a certain week Mr. Ramnath earned a total of $516.20, but $160.20 was for overtime. calculate how much per hour he is normally paid.
Answer:
$8.90
Step-by-step explanation:
first you have to subtract how much money you get for overtime, 516.20-160.20=356.00 Next you have to divide 356.00 by 40 to find per hour, 356.00/40=8.90.
Find the measurement and round to the nearest tenth.
[Law of Sines]
===================================================
Work Shown:
The uppercase letters A,B,C are the angles, while the lowercase counterparts (a,b,c) are the sides opposite those angles. For instance, side b is opposite angle B.
We have this known info:
A = 59 degreesC = 15 degreesc = 10 yardsThe ultimate goal is to find side BC, which is opposite angle A. So this is side a.
Now apply the law of sines to solve for 'a'.
sin(A)/a = sin(C)/c
sin(59)/a = sin(15)/10
10*sin(59) = a*sin(15)
a*sin(15) = 10*sin(59)
a = 10*sin(59)/sin(15)
a = 33.1184013279463
Make sure your calculator is in degree mode.
This rounds to the nearest tenth to get a = 33.1 which is the approximate length of side BC.

Answer: 3, 37
Step-by-step explanation:
Divide by 3, divide by 3 again. 37 is a prime number, so it can't be divided again after that.
In a sequence of numbers, a3=3, a4=7, a5=11, a6=15 a7=19.
Based on this information, which equation can be used to find the nth term in
the sequence?
Answer:
B, an = 4n - 9
Step-by-step explanation:
The sequence is for every time the exponent on a goes up one, the number that it equals to goes up by 4. So to find the nth term, we at 4 to n. I hope this helped! :)
