Answer:
1256.64
Step-by-step explanation:
To find the area of a circle, the formula is πr2.
R stands for radius, and since the radius of a circle is always half the diameter we can figure this problem out.
If the diameter is 40, the radius is 1/2 of that, so the radius is 20. Now knowing the radius is 20, plug that into our formula and then we'll get the answer.
A = πr2 = π · 20^2 ≈ 1256.63706
≈ 1256.64

I prepaid 70% of the total cost of $127.50 last week . The total you still owe is______?
Answer:
38.25
Step-by-step explanation:
Note:
Paid 70%
Total 127.50

Slope = (7,-1) and 12,-2)
Answer: -1/5
Step-by-step explanation:
the equation to solve slope with two points is the y coordinate in the second point minus the y coordinate in the first point over the x coordinate in the second point minus the x coordinate in the first point so this one would be
(-2 - -1)/(12-7)
On the top you subtract a negative it becomes a positive and you get -1/5

Answer:
Rectangle A's length = 22 ft., Rectangle B's length = 44 ft.
Step-by-step explanation:
Since we know that the length of Rectangle B is twice the length of Rectangle A, we know that 2*(3x + 7) = Rectangle B's length.
We must set this equation to the dimensions already given for Rectangle B, which gives us 2(3x + 7) = 2 (5x - 3).
Using the distributive property gives us 6x + 14 = 10x - 6 and solving for x gives us x = 5.
We must plug five into the original dimensions to find that the lengths of Rectangles A and B are 22 feet and 44 feet respectively.

Assume that all vectors are non-zero vectors in the statements below. Decide whether the following are true in all cases or false in at least one case.
Answer: pretty sure they’re all true
Step-by-step explanation:
1. Should be obvious once you realize that if they all are in the same plane, one of them is a linear combination of the other two (think about a mini R^2 situation on the plane)
2. If x,y,z are linearly independent, they all are in the same plane, so z can be written in terms of x and y. (Above reasoning again.)
3. Should be intuitively clear, but rigorously just do the contrapositive. If v1,v2 are linearly dependent, av1 + bv2 = 0 for some a,b, so you can do av1 + bv2 + 0v3 = 0 which means v1,v2,v3 are dependent as well.
4. Intuitively they all are in the same plane. But if you want to be rigorous, you can choose, for example, 5v1 + 0v2 + 0v3 = 0, so they are linearly dependent.
5. What this is really saying is there is no scalar k such that v1 = kv2. It should be clear they are independent, but again if you want to be rigorous, suppose (for contradiction) there are a,b such that av1 + bv2 = 0. Then v1 + (b/a)v2 = 0, so v1 = -(b/a)v2. But this violates the “k” thing we said before! Hence a contradiction, so such a combination is not possible and thus they are linearly independent.

What is trigonometric ratio?In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec, and cot in short.
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
Given, In figure
ΔDEF is right angle triangle
DE = 7.2
∠D = 42°
∠E = 90°
EF = d =?
tan D = EF/DE
tan 42° = d/7.2
0.900 = d/ 7.2
d = 6.48
Hence, 6.48 is the value of d in right angle ΔDEF.

Ms. Brooks put $1200 in a 3 retirement account that offers 8% interest compounded annually. Ms. Brooks makes no additional deposits or withdrawals. How much interest will Ms. Brooks have earned at the end of 2 years?
Answer:
$1,408.21.
Step-by-step explanation:
Since it is compounded annually we could use the formula
A=Pe^rt
We know that the initial amount she deposits is $1200, as stated by the problem. That is our P.
e is well, the e in your calculator which is approximately: 2.7182818284590452353602874713527
r is the rate which is 8%, although you must convert this into a decimal, which would be 0.08 as your r.
Lastly, t is the time, so in this case, 2 years.
And then plug in the values.
A=1200(e)^(0.08)(2)
A=1200(e)^(0.16)
A=1200(1.173510870991810235018611086892)
A=1,408.2130451901722820223333042704
Now since it is a money problem we must put it in the correct format.
A=$1,408.21
