Christine can spend up to 12 hours in the boat.

Answer:

width = 8 ft & length = 32 ft.

Step-by-step explanation:

let the width be x and length be 4x.

we know, Perimeter = 2(l+b)

now,

2(4x + x) = 80

10x = 80

x = 80/10 = 8

x = 8

therefore,

width = x = 8 ft

length = 4x = 4 × 8 = 32 ft.

The amount of stickers bought in the sticker exchange is an illustration of factors

There were 47 people in the sticker exchange

The number of stickers is given as:

Stickers = 141

Next, we list the factors of 141 in pairs

(x,y) = (1,141), (3,47), (47,3) and (141,1)

Each person bought more than 1 sticker.

So, we have:

(x,y) = (3,47) and (47,3)

Hence, we can conclude that there were 47 people in the sticker exchange

Scale 1cm=3m

Answer:

60 m

Step-by-step explanation:

Perimeter of a rectangle = 2 x width + 2 x length

From inspection of the diagram, the width of the villa is 4 cm and the length is 6 cm

Therefore, perimeter of the villa = (2 x 4) + (2 x 6) = 20 cm

We are told that there is a scale 1 cm : 3 m

This means that 1 cm = 3 m

Therefore, to convert the perimeter found in cm into meters, we need to multiply it by 3:

Perimeter = 20 x 3 = 60 m

The volume of the triangular prism is 58.32 in³

Volume is the amount of space occupied by a three dimensional object.

The volume of a triangular prism is given by:

V = Area of triangle * height

Area of triangle = (1/2) * 10.8 * 7.2 = 38.88 in²

Volume of prism = 38.88 * 1.5 = 58.32 in³

Answer:

PS = 7

SQ = 7.125

m<QTR = 115

m<TQR = 32.5

Step-by-step explanation:

To find PS, you need to take the measurement from QR [stated in the problem] which is 7 feet.

To find SQ, you need to take the measurement from RT [stated in the problem as 3 9/16] and then multiply it by 2 as SQ is 2 times longer than RT, which means SQ = 7 1/8 or 7.125 [since it needs to be a decimal]

To find m<QTR, you need to take the measurement from m<RTS, and since those 2 angles together equal 180, you need to subtract 65 degrees [from m<RTS] from 180, resulting in 115 degrees.

To find m<TQR, you need to know that a triangle has 180 degrees within it.  Then you need to find one angle.  We know the wider angle, <T = 115 degrees, so then we have to do 180 - 115, which equals 65 [that is the total for the 2 remaining equal corners], then we just have to divide by 2, which equals 32.5 degrees.

Answer:

Step-by-step explanation:

big brain question :)

Step-by-step explanation:

That depends on the tension on the tape.

As defined, the tape, due to gravity would form a catenary, a curve, so the measurement would be less than 30 m. The tension on the tape would affect the degree to which the measurement would be less. A tension well within the limits of the steel used to make the tape would be would be well within the accuracy of the tape. Over 30 m, the tape is likely +/- 2 mm, the recorded value could be 30m, +1mm/-3mm. If you need more than that degree of accuracy, you don’t use a tape.

The expression 8√y/x is equivalent to the given radical expression. The correct answer would be an option (D).

Any expression that contains a radical symbol is considered a radical expression. To find the square roots, cubic roots, and higher, radical symbols are used. For example, √7, √6, and √11 are in the radial form.

The radical expression is given as:

√(128x⁵y⁶/2x⁷y⁵)      (Assume x > 0 and y> 0)

Reduce the likewise variables,

√(64y/x²)

8√y/x

Thus, the expression 8√y/x is equivalent to the given radical expression.

Hence, the correct answer would be an option (D) 8√y/x.

Answer:

  sin(8w)/1024 -sin(4w)/128 +3w/128

Step-by-step explanation:

No doubt there are a variety of formulas and identities that can be used. Absent knowledge of those, I found it convenient to rewrite the integrand using Euler's formula. It tells you ...

  [tex]\sin(x)=\dfrac{e^{ix}-e^{-ix}}{2i},\quad\cos(x)=\dfrac{e^{ix}+e^{-ix}}{2}[/tex]

After some only slightly messy algebra, we find ...

  [tex]\cos^4(w)\sin^4(w)=\dfrac{\cos(8w)-4\cos(4w)+3}{128}[/tex]

Then the integral becomes straightforward:

  [tex]\displaystyle \int{\cos^4(w)\sin^4(w)}\,dw=\int{\dfrac{\cos(8w)}{128}}\,dw-\int{\dfrac{\cos(4w)}{32}}\,dw+\dfrac{3}{128}\int{}\,dw\\\\=\boxed{\dfrac{\sin(8w)}{1024}-\dfrac{\sin(4w)}{128}+\dfrac{3w}{128}}[/tex]

__

Additional comment

The slightly messy algebra involves the identities ...

  (a+b)(a-b) = a² -b²

  (a -b)⁴ = a⁴ -4a³b +6a²b² -4ab³ +b⁴

Recall the double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

This means the given integrand is equivalent to

cos⁴(w) sin⁴(w) = (cos(w) sin(w))⁴ = (1/2 sin(2w))⁴ = 1/16 sin⁴(2w)

Also recall the half-angle identities for sine and cosine:

cos²(x) = 1/2 (1 + cos(2x))

sin²(x) = 1/2 (1 - cos(2x))

Then we can rewrite further as

1/16 sin⁴(2w) = 1/16 (sin²(2w))²

… = 1/16 (1/2 (1 - cos(4w)))²

… = 1/16 (1/4 (1 - 2 cos(4w) + cos²(4w))

… = 1/64 (1 - 2 cos(4w) + 1/2 (1 + cos(8w)))

… = 1/128 (3 - 4 cos(4w) + cos(8w))

You'll end up with the same solution as in the other answer:

[tex]\displaystyle \int \cos^4(w)\sin^4(w) \, dw = \frac1{128} \int (3 - 4\cos(4w) + \cos(8w)) \, dw \\\\ = \frac{3w-\sin(4w)+\frac18\sin(8w)}{128} + C \\\\ = \boxed{\frac{24w-8\sin(4w)+\sin(8w)}{1024} + C}[/tex]

By using the graph and the definition of inverse functions, we will see that:

g⁻¹(1) = 4.

We say that two functions f(x) and g(x) are inverse if:

Now, we know that graph of g(x) and we want to find the value of:

g⁻¹(1)

In the graph, we can see that:

g(4) = 1

Then we can replace it:

g⁻¹(1) = g⁻¹( g(4) ) = 4.

So we can conclude that:

g⁻¹(1) = 4.

[tex]5x+40 = 5(x+8)[/tex]

Answer:

12 cupcakes were sold

11 brownies were sold

Step-by-step explanation:

Let c = number of cupcakes sold

Let b = number of brownies sold

Total number of items sold = 23

⇒ b + c = 23

cupcake = $1.50 each

brownie = $1.25 each

Total money made = $31.75

⇒ 1.5c + 1.25b = 31.75

Rewrite  b + c = 23  to make b the subject, substitute into 1.5c + 1.25b = 31.75 and solve for c:

⇒ b = 23 - c

⇒ 1.5c + 1.25(23 - c) = 31.75

⇒ 1.5c + 28.75 - 1.25c = 31.75

⇒ 0.25c + 28.75 = 31.75

⇒ 0.25c = 3

⇒ c = 12

So 12 cupcakes were sold

Substitute found value for c into  b + c = 23  and solve for b:

⇒ b + 12 = 23

⇒ b = 11

So 11 brownies were sold

Answer:

70

Step-by-step explanation:

The angle at the bottom right of the triangle is linear with the 105, so it is 180 - 105 = 75

The top angle of the triangle is an alternate interior angle with the 35 degrees, so it is also 35.

75 + 35 = 110

x = 180 - 110 = 70

The angle above x is 35° as alternate interior angles are equal.

Step-by-step explanation:

1)  y - 2 > 3

Add 2 to both sides:   y > 5

2) y ≤ 2

Draw a closed circle at y = 2 then shade the numbers to the left

3) y ≥ 250

where y = savings

4) The image isn't very clear, so I can't tell if it's a closed or open circle on -4.

If it is closed, it will be y ≤ -4

If it is open, it will be y < -4

5) -4 < f

Draw an open circle at f = -4 then shade the numbers to the right

6) x < -3.5

Draw an open circle at x = -3.5 then shade the numbers to the left

7) closed circle ... shade to the left of 8 ... make y  equal to or less than 8.

8) F ≤ 6

C - closed circle at 6 with shaded numbers to the left

9) y > 2.75

Betty saved more than $2.75 every month

10) 1 + x < 5

Subtract 1 from both sides:  x < 4

11) x ≥ -2.5

The only option for which the limit exist is option f, while for the other options the DNE.

"If the graph has a vertical asymptote and one side of the asymptote goes toward infinity and the other goes toward negative infinity, then the limit does not exist. If the graph has a hole at the x value c, then the two-sided limit does exist and will be the y-coordinate of the hole."

Let's check the values of the given quantity exist or not. Therefore, we can write,

(a) f(-2) = DNE

(b) [tex]\lim_{x \to \--2} f(x)[/tex] = DNE

(c) f(0) = DNE because hole are exist
