Domenica is creating a banner to hang outside her business. Her design is shown below. It is composed of a square and two equal right triangles, one on either side of he square.
Take into account that the figure at the center is a square. Its area is given by:
A1 = (8 ft)² = 64 ft²
To the area of the other two triangles, first determine the length of the below side of the triangle, as follow:
20 ft - 8 ft = 12 ft
12 ft is the length of the two sides. Due to both triangles are equal, the length of their sides is:
12 ft/2 = 6 ft
Then, the area of the triangles is:
A2 = (6 ft)(8 ft)/2 = 48 ft/2 = 24 ft
Hence, the total area of the figure is:
AT = A1 + A2 + A2
AT = 64 ft² + 24 ft² + 24 ft² = 112 ft²
The toal area of the figure is 112 ft²

D is directly proportional to x. D=36 when x=5. Work out the value of D when x=8
Step-by-step explanation:
D is directly proportional to x. D=36 when x=5. Work out the value of D when x=8.
Because they are directly proportional:
x/D = x/D
5/36 = 8/D
multiply both sides by D:
D(5/36) = D(8/D)
5D/36 = 8
multiply both sides by 36:
36(5D/36) = 8 * 36
5D = 288
divide both sides by 5:
5D/5 = 288/5
D = 288/5

find the number of subsets of 38,76,152,304
The number of subsets of {38,76,152,304} are 32.
What is subset?If every element of set A is also an element of set B, then set B is a superset of set A and set A is a subset of set B. A and B could be equal; if they are not, then A is a legitimate subset of B. Include refers to the property that one set is a subset of another. If every element in a set A is also an element in a set B, then the set A is a subset of the set B. The set A is therefore contained within the set B. A⊂B is used to represent the subset connection.

If the 20th term is -40 and your 28th term is -73, what will be the first term
Answer:
The first term will be 38.375
Step-by-step explanation:
aₙ = a₁ + (n - 1) * d
a₂₀ = -40
a₂₈ = -73
-40 = a₁ + 19d
-73 = a₁ + 27d
When we have two similar equations with two unknowns, we can subtract them to get an answer.
-40 = a₁ + 19d --> -40 = a₁ + 19d
-(-73 = a₁ + 27d) --> 73 = -a₁ - 27d
-------------------------------------------------
33 = -8d
Solve for d by dividing by -8
d = -4.125
Now plug d into one of the original equations to solve for a₁
-40 = a₁ + 19(-4.125)
-40 = a₁ - 78.375
a₁ = 38.375
let v be a vector space over a field of characteristic not equal to two. (a) let u and v be distinct vectors in v. prove that {u, v} is linearly independent if and only if {u v, u − v} is linearly independent. (b) let u, v, and w be distinct vectors in v. prove that {u, v, w} is linearly independent if and only if {u v, u w, v w} is linearly independent.
Thus {u, v} is linearly independent if and only if {u v, u − v} is linearly independent
It is given that {u,v} be a linearly independent set of a set S.
This means that there exist constant a,b such that if:
au+bv=0
then a=b=0
Now we are asked to prove that:
{u+v,u-v} is a linearly independent set.
Let us consider there exists constant c,d such that:
c(u+v)+d(u-v)=0
To show: c=d=0
The expression could also be written as:
cu+cv+du-dv=0
( Since, using the distributive property)
Now on combining the like terms that is the terms with same vectors.
cu+du+cv-dv=0
i.e.
(c+d)u+(c-d)v=0
Since, we are given that u and v are linearly independent vectors this means that:
c+d=0------------(1)
and c-d=0 i.e c=d-----------(2)
and from equation (1) using equation (2) we have:
2c=0
i.e. c=0
and similarly by equation (2) we have:
d=0
Hence, we are proved with the result.
We get that the vectors {u+v,u-v} is linearly independent.

Would you rather have a savings account that pays 5% interest compounded semiannually or one that pays 5% interest compounded daily? Explain
A compound interest that pays 5% interest compounded daily is preferable. This is so even though the interest rates on the two accounts are equal, the 5% interest compounded daily account is used more frequently.
What is difference between simple interest and compound interest ?Interest is the cost of borrowing money, such as the sum added to a loan debt. It is also possible to classify the rate paid for holding money on deposit, such as in the case of a certificate of deposit. The two ways to calculate interest are simple interest and compound interest.
On the principal, or original loan amount, of a loan, simple interest is calculated.
Since compound interest is calculated using both the principal and the accrued interest from previous periods, it is frequently referred to as "interest on interest".
If interest is computed on a compound basis rather than a simple basis, the amount of interest that must be paid on a loan can vary significantly. Positively speaking, the magic of compounding may be a powerful tool for wealth growth and can work in your favor when it comes to your assets.
Simple interest and compound interest are fundamental financial concepts, but understanding them thoroughly may enable you to make better choices when applying for a loan or making investments.

R is directly proportional to T. If R = 60 when T = 10, Calculate the value of R when T = 7
Answer:
R = 42
Step-by-step explanation:
given R is directly proportional to T , then the equation relating them is
R = kT ← k is the constant of proportion
to find k use the condition R = 60 when T = 10
60 = 10k ( divide both sides by 10 )
6 = k
R = 6T ← equation of proportion
when T = 7 , then
R = 6 × 7 = 42

Triangle may be defined as a closed figure having three sides and three interior angles. The above question can be solved by using the exterior angle theorem of triangle. The exterior angle of a triangle theorem states that the measure of the angle formed, when one side of a triangle is extended, is equal to the sum of the opposite interior angles of that triangle. Applying the exterior angle of a triangle theorem:
m∠WUV + m∠UVW = m∠VWX
Substitute the values of angles.
(2x + 8) + (3x + 16) = (8x - 18)
5x + 24 = 8x - 18
5x - 8x = -24 - 18
-3x = -42
=> x = -42/-3
=> x = 14
So, the angle m∠WUV = 2x + 8
Putting in the value of x
m∠WUV = 2(14) + 8
m∠WUV = 28 + 8
m∠WUV = 36° which is required value.
