Answer:

the total available area = (3x^2 + 4x + 1) - (2x^2 + 8x + 8) = x^2 - 4x - 7

Step-by-step explanation:

The question seems to ask available area and not how much wallpaper is required. Let's calculate the area of the rectangular window. Area of a rectangle = Length * Breath Area = (x + 2) * (x + 1) = x^2 + 3x + 2 The wall also has a built- in shelving unit that occupies an area of (x^2 + 5x + 6). So total area occupied by the rectangular wall and shelf is (x^2 + 3x + 2) + (x^2 + 5x + 6) = 2x^2 + 8x + 8. If the wall is to be covered with wallpaper

Answer:

B

Step-by-step explanation:

The intercepted angle is given as "34x+4"

The arc is 196.

Any intercepted angle of an arc that falls in the opposite circumference, it will have a measure half that of the arc intercepted.

Hence,

34x+4 = (0.5)(196)

34x + 4 = 98

34x = 98 - 4

34x = 94

x = 94/34 = 2.76

Part 2) Area of semicircle [tex]1,413\ ft^{2}[/tex]

Par 3) Total area of grass [tex]2,187\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The total area of grass is equal to the area of rectangle minus the area of semicircle

step 1

Find the area of rectangle

The area of rectangle is equal to

[tex]A=45*80=3,600\ ft^{2}[/tex]

step 2

Find the area of semicircle

The area of semicircle is equal to

[tex]A=\frac{1}{2}\pi r^{2}[/tex]

we have

[tex]r=60/2=30\ ft[/tex] -----> the radius is half the diameter

substitute

[tex]A=\frac{1}{2}(3.14)(30)^{2}[/tex]

[tex]A=1,413\ ft^{2}[/tex]

[tex]f(t)=sin(\pi(t -3)) + 4[/tex]

Step-by-step explanation:

The general sine function has the following form  

[tex]y = Asin(bt-\phi) + k[/tex]

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

[tex]\frac{2\pi}{b}[/tex] is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

[tex]\phi[/tex] phase shift

We know that:

amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Thus:

[tex]A =1[/tex]

[tex]\frac{2\pi}{b}=2[/tex]

[tex]b=\pi[/tex]

[tex]\phi=3[/tex]

[tex]k=4[/tex]

Then the function is:

[tex]f(t)=sin(\pi(t -3)) + 4[/tex]

The answer is last option

D. Infinite intersection points

Divide both sides of the second equation by 2 to find that it is equal to y = 4 - x, which is the same as the first equation.

Since they are the same equation, they are always touching each other since they are the exact same line, which means they are always intersecting, and there are infinite intersection points.

ANSWER

See attachment.

EXPLANATION

The cosine function is symmetric with respect to the y-axis.

If the cosine function has an amplitude of 2 then, its range is

The true annual interest rate for this loan is approximately 1.44 or 144%.

The Breakdown

To calculate the true annual interest rate, we can use the formula for calculating the interest rate on a loan:

True Annual Interest Rate = [(Monthly Payment Amount × Number of Payments) / Loan Amount - 1] × 12

Given the information provided:

Loan Amount = $3,000

Number of Payments = 36

Monthly Payment Amount = $93.33

Substituting these values into the formula:

True Annual Interest Rate = [(93.33 × 36) / 3000 - 1] × 12

Calculating this expression:

True Annual Interest Rate = [(3360 / 3000) - 1] × 12

True Annual Interest Rate = (1.12 - 1) × 12

True Annual Interest Rate = 0.12 × 12

True Annual Interest Rate = 1.44

Therefore, the true annual interest rate for this loan is 1.44 or 144%.

Be the sides x[tex]x, x+6[/tex] you know [tex]x(x+6) = 112[/tex] or [tex]x^2 +6x -112 = 0[/tex][tex]x= -3 \pm \sqrt{9+112} = -3\pm 11[/tex] the solution is [tex]x=8, x=-14[/tex] The negative answer is to be discarded, your rectangle has sides 8 and [tex]8+6=14[/tex] miles

The length of the rectangle is 14 miles and the width of the rectangle is 8 miles.

For a rectangle with length and width L and W units, we get:

Area of the rectangle = (L × W) unit^2

Perimeter of the rectangle = 2(L + W) units

Let the width of the rectangle be represented by W, while the length is represented by L.

Given the width is 6 miles less than its length, therefore, the width can be written as,

W = (L - 6) miles

Now given the area of the rectangle is 112 sq. miles, therefore, the area of the rectangle can be written as,

Area of the rectangle = Length × Width

112 = L × W

112 = L × (L-6)

112 = L²-6L

L = 14, -8

Since the length, L can not be negative, the value of L is 14 miles, therefore, the width will be 8 miles.

Hence, the length of the rectangle is 14 miles and the width of the rectangle is 8 miles.

P(A ∩ B ∩ C) is 1/25 ⇒ answer D

Step-by-step explanation:

* Lets talk about the Venn diagram

- There are three circles intersect each other

- The number of elements ∈ (A ∩ B) and ∉ C = 5

∴ n(A ∩ B) and ∉ C = 5

- The number of elements ∈ (A ∩ C) and ∉ B = 6

∴ n(A ∩ C) and ∉ B = 6

- The number of elements ∈ (C ∩ B) and ∉ A = 4

∴ n(C ∩ B) and ∉ A = 4

- The number of elements ∈ (A ∩ B ∩ C) = 2

∴ n(A ∩ B ∩ C) = 2

- The number of elements ∈ A and ∉ B , C = 9

- The number of elements ∈ B and ∉ A , C = 8

- The number of elements ∈ C and ∉ A , B = 7

- The number of elements ∉ A , B , C = 9 ⇒ outside the circles

- The total elements in the Venn diagram is the sum of all

  previous numbers

∴ The total number in the Venn diagram = 5 + 6 + 4 + 2 + 9 + 8 + 7 + 9 =

  50

* To find the probability of (A ∩ B ∩ C), find the total number in

  the Venn diagram and the number of elements in the intersection

  part of the three circles

∵ The total elements in the Venn diagram = 50 elements

∵ n(A ∩ B ∩ C) = 2

∴ P(A ∩ B ∩ C) = 2/50 = 1/25

* P(A ∩ B ∩ C) is 1/25

Please mark me as brainliest if this answer is correct and nobody tops it.

Answer:

46°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

Cos = Adjacent/Hypotenuse

You are given the lengths of the hypotenuse of the triangle and the side adjacent to the angle you want to find. So, the cosine function describes the relationship:

cos(B) = AB/CB = (20 cm)/(29 cm)

B = arccos(20/29) ≈ 46.397°

B ≈ 46°

The student is looking for the value of an angle, m∠B, which requires solving an equation and rounding to the nearest integer. The provided information does not give a direct method or equation for calculating m∠B, thus an answer cannot be given confidently.

The student is asking to calculate the value of an angle, denoted as m∠B, to the nearest degree. This is a mathematics problem likely involving geometry or trigonometry.

In the information provided, different equations and scenarios for calculating angles and magnitudes are given, but they seem to be disconnected, and the specific question regarding m∠B isn't directly addressed by the provided equations and examples.

Without a direct relationship or equation including m∠B, or a diagram to reference, it is not possible to confidently provide the value of m∠B. However, the excerpts suggest that if we had an equation and needed to find an angle such as m∠B, we would solve the equation and then round the result to the nearest integer, as angles are typically given in integers when degrees of freedom are considered.

Answer:

  Stock A and Stock B

Step-by-step explanation:

After 1 year, the value of Stock A is 58/50 = 1.16 times what it was, an increase of 16%.

After 1 year, the value of Stock B is 29/25 = 1.16 times what it was, an increase of 16%.

The bond has coupon value of $298.90 each year, about 5.02% of the amount invested. (However, the value of the bond at the end of 4 years is only $3500, so represents a net loss of about $1254.40 over that time period. We're not quite sure why Norvin purchased this bond at that price.)

Answer:

The correct option is option A

Step-by-step explanation:

We have the following expression:

sqrt(18x^3) - sqrt(9x^3) + 3sqrt(x^3) - sqrt(2x^3)

We know that sqrt(a*b) = sqrt(a)sqrt(b)

Applying this, we have:

sqrt(18)sqrt(x^3) - 3sqrt(x^3) + 3sqrt(x^3) - sqrt(2)sqrt(x^3)

sqrt(x^3)[ sqrt(18) - sqrt(2)]

sqrt(x^3)[ 3sqrt(2)- sqrt(2)]

sqrt(x^3)[2sqrt(2)]

Then we now that:

sqrt(x^3)[2sqrt(2)] = 2x*sqrt(2x)

The correct option is option A

Step-by-step explanation:

This is easier to follow if you write it out the long way.

g(x) = (x + 3)/x

g(f(x)) = (f(x) + 3)/f(x)

g(x^2 - 7) = (x^2 + 7 + 3)/(x^2 + 7)

g(x^2 - 7) = (x^2 +10 ) / (x^2 + 7)

g(-5) = ( (-5)^2 + 10) / ( (-5)^2 + 7)

g(-5) = ( 25 + 10) / (25 + 7)

g(-5) = 35/32
