the area is
A = length × width.
length = 3 × width
=>
A = 3 × width × width = 3 × width²

The functions r and s are defined as follows.
r(x)= -2x-2
s(x)=2x² +2
Find the value of s (r (2)).
[tex]r(x) = -2x-2\\ s(x) = 2x^2+2[/tex]
[tex]s\big(r(2)\big) = s(-2\cdot 2-2) = s(-4-2) = s(-6) = 2\cdot(-6)^2+2 = 2\cdot 36+2 =\\ = 72+2 = 74[/tex]
[tex]\Rightarrow \boxed{s\big(r(2)\big) = 74}[/tex]
Answer:
74Step-by-step explanation:
Given functions:
r(x) = -2x - 2 s(x) = 2x² + 2Find s(r(2)) in steps:
r(2) = -2*2 - 2 = - 4 - 2 = - 6s(r(2)) = s(- 6) = 2(-6)² + 2 = 72 + 2 = 74how do you determine volume?
Answer: V = πr 2 h
Step-by-step explanation:
To calculate the volume of a cylinder, you must know its height and the radius of the circular base (the distance from the center of the circle to its edge) at the top and bottom. The formula is V = πr 2 h, where V is the Volume, r is the radius of the circular base, h is the height, and π is the constant pi.

How do you solve 4 over 5 times 3.75
Answer:
3
Step-by-step explanation:
First of all simplify 4/5 to .8
Then Multiply: .8*3.75=3
9514 1404 393
Answer:
4/5×3.75 = 3
Step-by-step explanation:
There are many solution strategies available. Among them are ...
use a calculator to find 4/5×3.75 = 3convert the numbers to decimal and multiply by hand 0.8×3.75 = 3.000compute 2(2×3.75)/5 = 2(7.5)/5 = 15/5 = 3 in your headconvert 3.75 to an improper fraction and multiply (4/5)(15/4)=15/5=3__
Additional comment
The mental arithmetic involved in adding a number to itself (doubling a number) is usually pretty easy. This means it is relatively easy to multiply by powers of 2, such as 4, 8, or 16. The second strategy listed above can be done in your head as ...
8/10×3.75 = 2×(2×(2×3.75))/10 = 2×(2×7.5)/10 = 2×15/10 = 30/10 = 3
The same product can be found as ...
8/10×3.75 = 8×(3.75/10) = 8×0.375 = 8×(3/8) = 3
In all cases, it is helpful to know your times tables, decimal equivalents of common fractions, and a few shortcut strategies for mental arithmetic. These are not difficult, but they do require you put some effort into memorizing them.

If your goal is to retire with at least $1 million, how long would it take—and how much would you need to invest each month—if your anticipated rate of return is 10%? At what age could you retire if you started investing at age 25?
Answer:
There is no simple one size fits all answer to this question, because I need a few more variables to solve it. Or you can go to bankrate.com and use the millionaire calculator and figure it out on your own. I put a sample in the photo.
Hope this helps!;)
Step-by-step explanation:
1. Your age= 25
2. Target age=? obviously you don't want to be too old to spend it.
3. Current investments=? how much are you starting with 0 or more?
4. Savings per month=? only you know how much you can set aside out of your income
5. Expected rate of return=10%
6. Expected inflation rate= 2.9% (last I heard 2021)

newton's second law of motion States that the acceleration of an object is directly proportional to the force exerted on the object. if an object accelerates at a rate of 3 m/s2 , it will exert a force of 15 N. how much force will the same object exert if it accelerates at a rate of 7 m/s2?
pls pls pls help (๑•﹏•)
Answer:
Step-by-step explanation:
F=(2kg)×(3ms2). ∴F=6kgms2=6 Newton. =6N. Therefore, Force required to accelerate the body is 6N
The force the same object will exert if it accelerates at a rate of 7 m/s² is 35 N
From the question,
We have that,
Newton's second law of motion states that the acceleration of an object is directly proportional to the force exerted on the object
Let a represent the acceleration and F represent the force exerted
Them we can write that
F ∝ a
Introducing a constant, m, which is the mass of the object
Then, we get
F = ma
From the question,
If an object accelerates at a rate of 3 m/s² , it will exert a force of 15 N
We will the determine the mass, m, of the object using the above formula
F = ma
We have that
a = 3 m/s²
F = 15 N
Using
F = ma
Then,
15 = m × 3
m = 15÷3
∴ m = 5kg
Now, we can determine the force the same object would exert if it accelerates at at rate of 7 m/s²
Using the same formula
F = ma
a = 7 m/s²
m = 5 kg
∴ F = 5 × 7
F = 35 N
Hence, the force the same object will exert if it accelerates at a rate of 7 m/s² is 35 N

Sami's bank account earns 4% simple interest per year. If Sami deposits $500, how much simple interest will she earn in four years?
Answer:
$80 simple interest.
Step-by-step explanation:
That is correct because the simple interest that Sami earns is 4% each year and 4% of %500 is $20. So if she will earn $20 in simple interest a year then in four years she will have earned $80.

Ok so if you were wondering what to do on the box that says this
Move Decimal

Bring down
On this, I agree with myself. The solution is straightforward. Simply click them in the sequence listed, beginning with the first and ending with the last. Wow, what sleuthing I did. I realize it's not much, but I was perplexed by this as well, so you could be as well. So here we go with the actual answer. To tackle these sorts of issues, you must employ a technique known as PEMDAS, which stands for.
Parenthisis
Exponent
Multiply
Divide
Add Subtract
I realize I spelt the first one incorrectly, but it's 2 a.m. and I'm doing homework for you. Now we must consider whether or not this has any parenthesis. This particular issue does not. Now we must determine whether or not this issue has exponents, which it does. As mentioned in the response box on the lesson's main page. So we have to consider that (spelled incorrectly, but who cares, it's math class)Now we multiply by a power of ten, so the divisor is a whole number. The following step is to divide by calculating how many times 25 equals 105. I realize it was stolen from the question, but whatever. So there was the explanation; I realize I didn't answer the entire problem, but I didn't have to; it wasn't in the cards.
