Paige is sewing a tent. If the material cost $0.04 per square in, determine how much it will cost her to make the tent.

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

Answer:

$25

Step-by-step explanation:

$20 = 80%

100% to 80% = x 0.8 ( you have to do inverse)

$20/ 0.8 = $25

The monthly rent of the apartment in the 10th year is  $1041.67.

The first step is to determine the yearly rent in the first year of living in the apartment.

Yearly rent = $900 x 12 = $10,800

The second step is to determine the yearly rent in the 10th year

$10,800 + (170 x 10) = $12,500

The third step is to determine the monthly rent

Monthly rent = $12500 / 12 = $1041.67

#c

#d

#e

#f

Same like f(2)

#g

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

(d) [tex]\lim_{x \to \-0} f(x)[/tex] = DNE

(e) f(2) = DNE

(f) [tex]\lim_{x \to \-2} f(x)[/tex] = 0.5 (exist)

(g) f(4) = DNE

(h) [tex]\lim_{X \to \-4} f(x)[/tex] = DNE

Hence, the only option for which the limit exist is option f.

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]

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

Answer :

2 hours 36 minutes

Step-by-step explanation :

speed = distance / time

Distance = 150 km

time = 1 hour 30 minutes

= 1,5 hours

[tex]speed = \frac{150 \: km}{1.5 \: hours} [/tex]

[tex] speed = 100 \: km/hour[/tex]

How long will it take the car to cover a distance of 260 km at the same average speed ?

Time = Distance/Speed

= 260 km / 100 km/hour

= 2,6 hours

____________________

to convert hours to hours and minutes we can multiply by 60.

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.

The complete question is attached below.

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

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.

All below;

Green question mark = 10

50 (longer opposite side) - 40 = 10

Red question mark = 20

30 (longer opposite side) - 10 = 20

Perimeter = 160

30 + 50 + 10 + 40 + 20 + 10 = 160

Area = 700

30 * 50 = 1500; (Total area if it were fully a rectangle)

40 * 20 = 800; (Chunk of rectangle that is missing)

1500 - 800 = 700 (Total area - missing space)

Green question mark = 14

Opposite of the other side

Red question mark = 20

35 (longer opposite side) - 15 = 20

Perimeter = 152

35 + 22 + 20 + 14 + 10 + 14 + 15 + 22 = 152

Area = 630

35 * 22 = 770; (Total area if it were fully a rectangle)

14 * 10 = 140; (Chunk of rectangle that is missing)

770 - 140 = 630 (Total area - missing space)

The radius of the circle is a line from the center of the circle to its circumference

The radius of the circle with the same vertex as a center is 10.16 units

From the question, we understand that:

Start by calculating the area of the triangle using:

[tex]Area = 0.5ab\sin C[/tex]

So, we have:

[tex]Area = 0.5 * 12 * 12\sqrt 3 *\sin (60)[/tex]

This gives

[tex]Area = 0.5 * 12 * 12\sqrt 3 * \frac{\sqrt 3}{2}[/tex]

[tex]Area = 108[/tex]

The arc divides the triangle into two equal regions.

So, the area of the arc is:

[tex]Arc = 0.5 * Area = 0.5 * 108[/tex]

[tex]Arc = 54[/tex]

Also, the area of the arc is:

[tex]Arc = \frac{\theta}{360} * \pi r^2[/tex]

So, we have:

[tex]Arc = \frac{60}{360} *3.14 * r^2[/tex]

Simplify

[tex]Arc = 0.523 * r^2[/tex]

This gives

[tex]0.523 * r^2 = 54[/tex]

Divide both sides by 0.523

[tex]r^2 = 103.25[/tex]

Take the square roots of  both sides

[tex]r = 10.16[/tex]

Hence, the radius of the circle with the same vertex as a center is 10.16 units

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.

Angle aside right to x

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.
