Answer:
Length = 6.1 inches and Width = 3.4 inches
Step-by-step explanation:
We are told that the diagonal measures 7 inches.
We are also told that the length of the screen is 2.7 inches more than the width.
Let the length be L and width be W.
Thus, L = W + 2.7
Now, since length = W + 2.7 and width = W and diagonal = 7 inches, we can use pythagoras theorem to solve.
Thus;
W² + (W + 2.7)² = 7²
W² + W² + 5.4W + 7.29 = 49
2W² + 5.4W - 41.71 = 0
Using quadratic formula, we have;
W = [-5.4 ± √(5.4² - 4(2 × -41.71))]/(2 × 2)
W = [-5.4 ± √(362.84)]/4
W = -5.4/4 ± 19.05/4
W = (-1.35 + 4.7625) or (-1.35 - 4.7625)
W ≈ 3.4 inches or -6.1
W cannot be negative, thus, W = 3.4 inches
From earlier, we saw that L = W + 2.7
Thus,L = 3.4 + 2.7 = 6.1 inches
So, Length = 6.1 inches and Width = 3.4 inches
Use S = n^2 to find the sum of 1 + 3 + 5 + . . . + 701.
Answer:
123201
Step-by-step explanation:
This is an arithmetic sequence of common difference 2 and starting value 1,
So we can use the formula for an arithmetic sequence if we know what is the order of the last term.
Then first use the formula for the nth term to find "n":
[tex]a_n=a_1+(n-1)d[/tex]
where d = 2, first term = 1 and last term = 701
[tex]a_n=a_1+(n-1)d\\701=1+(n-1)*2\\700=(n-1)*2\\350=n-1\\n = 351[/tex]
Knowing this, we can estimate the partial sum:
[tex]S=n\,\frac{a_1+a_n}{2} \\S=351\,\frac{1+701}{2} \\S=351\,*\,351\\S = 123201[/tex]

The graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x + k. If g(x) is obtained by shifting f(x) up by 5 units, then what is the value of k?
Answer:
k = 5
Step-by-step explanation:
The value of k is added to each y-coordinate, so represents the amount of up-shift. If the shift up is 5 units, then k=5.

Which equation can be used to represent the statement? The sum of one-sixth of a number and negative two is equal to negative two-thirds. One-sixth + n = negative 2 + two-thirds One-sixth + n = negative 2 + (negative two-thirds) One-sixth n + 2 = negative two-thirds One-sixth n minus 2 = negative two-thirds
Answer:
One-sixth n minus 2 = negative two-thirds
Step-by-step explanation:
"one-sixth of a number" is represented by "one-sixth n". The sum of that and -2 is represented by "one-sixth n minus 2". Of course, "is equal to negative two-thirds" means "= negative two-thirds". Hence the equation you're looking for is ...
One-sixth n minus 2 = negative two-thirds
Answer:
One-sixth n minus 2 = negative two-thirds

9v=27 what the answer and solve
Answer:
V=3
Step-by-step explanation:
9v=27
You have to get v on its own so you have to do the inverse operation which in this case would be division, 9/9, what you do to one side you have to do to the other so 27/9
That’s would separate v from the other numbers and so V=3
9v=27
9v/9=27/9
V=3
Answer: v=3
Step-by-step explanation:
Simplifying
9v + -27 = 0
Reorder the terms:
-27 + 9v = 0
Solving
-27 + 9v = 0
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '27' to each side of the equation.
-27 + 27 + 9v = 0 + 27
Combine like terms: -27 + 27 = 0
0 + 9v = 0 + 27
9v = 0 + 27
Combine like terms: 0 + 27 = 27
9v = 27
Divide each side by '9'.
v = 3
Simplifying
v = 3

Answer:
[tex]a=2K-b[/tex]
Step-by-step explanation:
[tex]K=\frac{a+b}{2}[/tex]
Switch sides:
[tex]\frac{a+b}{2}=K[/tex]
Multiply both sides by 2:
[tex]\frac{2\left(a+b\right)}{2}=2K[/tex]
[tex]a+b=2K[/tex]
Subtract b from both sides:
[tex]a+b-b=2K-b[/tex]
[tex]a=2K-b[/tex]

The translation rule is (x,y) (x+_,y+_)
Answer:
see below
Step-by-step explanation:
The question is not clear but I will provide info based on given
Translation of
(x, y) → (x + a, y+ b)means sliding by a points to left/right and by b points to up/down
Find the derivative of the function. y = sin−1(6x + 1)
If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:
[tex]y=\sin^{-1}(6x+1)\implies\sin y=6x+1[/tex]
(true for y between -π/2 and π/2)
Now take the derivative of both sides and solve for it:
[tex]\cos y\dfrac{\mathrm dy}{\mathrm dx}=6[/tex]
[tex]\dfrac{\mathrm dy}{\mathrm dx}=6\sec y[/tex]
[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\cos\left(\sin^{-1}(6x+1)\right)}[/tex]
[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\sqrt{1-(6x+1)^2}}[/tex]
Eight avocados cost $4.
How much do 16 avocados cost?
How much do 20 avocados cost?
How much do 9 avocados cost?
16 avocados costs = $8, 20 avocados costs = $10 and 9 avocados costs = $4.5
What is the Cost?The amount of money that a company spends on the creation or production of goods or services.
Given that, Eight avocados cost $4.
Therefore, each of them costs = 4/8 = 1/2
So, 16 avocados = 16*1/2 =$8
20 avocados = 20*1/2 =$10
9 avocados = 9*1/2 =$4.5
Hence, 16 avocados costs = $8, 20 avocados costs = $10 and 9 avocados costs = $4.5

$12.23
$43.87
$56.10
$68.33
Answer:
$43.87
Step-by-step explanation:
Elijah has decided to lease her car for years. She will be earning lease rental on the car along with interest. The interest charges on the lease rentals is amortized at the lease interest rate. The lease interest rate for the vehicle is decided to be 41%.
Year 1 : $20,000 * 41% * 0.045 * .025 = $18.20
Year 2 : ($20,000 - $18.20) * 41% * 0.045 * 0.25 = $25.67
The sum of year 1 and year 2 is $43.87.
