Answer:

220

Step-by-step explanation:

The surface area is  given by

SA = 2 ( lw+wh+lh)  where  l is length h is height and w is width

SA = 2(3*4 + 3*14+ 4*14)

     = 2(12+42+56)

    = 2(110)

    = 220

The calculated surface area of the net is 208 square units

Finding the surface area of the net

From the question, we have the following parameters that can be used in our computation:

The net of the prism

The surface area of the net is then calculated as

Surface area = Area of big rectangle + 2 * Area of small rectangle

So, we have

Surface area = (14 + 3 + 14) * 4 + 2 * 3 * 14

Evaluate

Surface area = 208

Hence, the surface area of the net is 208 square units

Step-by-step explanation:

Answer:

x = 2

y = -1

Step-by-step explanation:

Since it gives you the value of y already, just plug that into the equation, like so:

y = 4x - 9

x - 3 = 4x - 9

Subtract the x from both sides:

x - 3 = 4x - 9

-x       - x

__________

-3 = 3x - 9

Then, add 9 to both sides:

-3 = 3x - 9

+9        + 9

________

6 = 3x

Divide both sides by 3:

2 = x

Now plug in x for y:

y = x - 3

y = 2 - 3

y = -1

Answer:

y = 3 (x+8)^2  -7

Step-by-step explanation:

The vertex form of the equation is

y = a(x-h)^2 +k

where (h,k) is the vertex

y = a (x- -8)^2 + -7

y = a (x+8)^2  -7

Now substitute the point into the equation to determine a

-4 = a (-7+8)^2  -7

-4 = a (1^2) -7

-4 = a -7

Add 7 to each side

-4+7 = a-7+7

3 =a

y = 3 (x+8)^2  -7

Answer:

y = 3(x + 8)² - 7

Step-by-step explanation:

y = a(x - -8)² - 7

y = a(x + 8)² - 7

-4 = a(-7 + 8)² - 7

3 = a

y = 3(x + 8)² - 7

Answer:

A≈351.86 or rounded to the nearest tenth, 351.9.

Answer:

Your answer should be A.

Step-by-step explanation:

To begin, you must acknowledge the formula for the SA or Surface Area of a Cylinder. Which is: 2πrh+2πr2

Now, we plug it in!

2π4×10 + 2π16

How do I know this?

Your radius if 4, since it's half of the cylinder. Since the second part calls for your radius squared, you must do 4x4.

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

Solving for A gets A = 90-B

So we end up with

sin(90-B) = cos(B)

which is the same as

cos(B) = sin(90-B)

Step-by-step explanation:

f(n) = - 29 - f( n - 1 )

f(1) = - 16

Now

f(2) = - 29 - f ( 2 - 1 )

= - 29 - f ( 1)

= -29 - ( - 16)

= - 29 + 16

Interior Angles - Angles that appear INSIDE the transversal

Transversal - The shape you see with two parallel lines intersecting it.

Alternate - Opposite of each other, on the other side as well.

The alternate interior angles are the pair of ∠2,∠8 and ∠3,∠5.

Alternate interior angles are the angles which are formed when two parallel lines cut by a transversal line.

Hence, the pair ∠2,∠8 and ∠3,∠5 are alternating interior angle.

Final answer:

The center of the given circle is at (13, 1), and the radius of the circle is 2.

Explanation:

The equation of a circle is generally given in the form (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius. Looking at the given equation (x - 13)^2 + (y - 1)^2 = 4, we can see that it is already in this standard form.

To answer the questions:

The center of the circle is (13, 1), which comes from the terms within the parentheses being subtracted from x and y.

The radius of the circle is not simply 4, as one might surmise by a quick glance. Instead, the equation gives us the radius squared, r^2 = 4. Taking the square root of both sides, we find that the radius, r, is 2.

Answer:

Susan invested some money (M) at 6% annual interest and 800 dollars at 7%. The money earned 128 dollars interest in a year. Then we have:

M x 6/100 + 800 x 7/100 = 128

=> M*0.06 = 128 - 800*0.07 =  128 - 56 = 72

=> M = 72/0.06 = 1200 dollar

The circle moves down

the circle moves left

the circle's radius increases

I took the test

The circle radius increases , the circle moves down and the circle moves left.

A circle is special kind of "ellipse in which eccentricity is zero and the two foci are coincident".

According to the question,

The circle x² + (y-7)² = 49. When the given circle changes (x+5)² + (y-4)² = 64

Equation of the circle = (x-a)² + (y-b)² = r²

x² + (y-7)² = 49

(x-0)² + (y-7)² = (7)²

The circle has center (0,7) and radius is 7.

Circle changes (x+5)² + (y-4)² = 64

(x+5)² + (y-4)²  = (8)²

The circle has center (5,4) and the radius 8.

Below diagram clearly shows the circle radius increases , the circle moves down and the circle moves left.

Answer:

Perimeter and area of drawing

Perimeter= 10 In

Area = 6.25 In²

Perimeter and area of object

Perimeter = 51.836 mm

Area = 167.936 mm²

Step-by-step explanation:

We are dealing with a square object, so let's talk about the drawing first.

The length of one side = 2.5 In

Perimeter of square= 4L

Perimeter = 4*2.5

Perimeter= 10 In

Area = L*L

Area = 2.5*2.5

Area = 6.25 In²

Letd note that 1 inch =

25.4 millimetres

So 2.5 Inch = 2.5 * 25.4

2.5 In = 63.5 mm.

25.4 mm is to 5mm

63.5 mm is to (63.5*5)/24.5

63.5mm is to 12.959 mm

So the length of actual object is 12.959mm

The perimeter = 4*12.959

Perimeter = 51.836 mm

Area = 12.959²

Area = 167.936 mm²

Answer:

The perimeter of the actual object  is 50 mm.

The area of the actual object is 156.25 mm square

Step-by-step explanation:

Given

Shape: Square

Scale: 1 in : 5 mm

Length of Scale Drawing = 2.5 in

Required:

- Perimeter of Actual Object

- Area of Actual Object

Calculating the perimeter of the actual object

Provided that the shape is a square;

The perimeter of the actual object is calculated by

Perimeter = 4 * Length

Recall that the scale is 1 in : 5 mm

This means 1 in on the scale represents 5 mm of the actual measurements of the object.

So, if 1 in ≈ 5 mm, then

2.5 in ≈ 2.5 * 5 mm

2.5 in = 12.5 mm

So, Length = 12.5mm

Now, the perimeter of the actual object can be calculated.

P = 4 * 12.5mm

P = 50mm

Hence, the perimeter of the actual measurements is 50 mm.

Calculating the area of the actual object

The area of the actual object is calculated by

Area = Length * Length

Recall that Length = 12.5 mm as calculated above

So,

Area = 12.5 * 12.5

Area = 156.25 mm square

Hence, the area of the actual object is 156.25 mm square

The intensity of a sound of 10³² w/m² is 440 decibels.

An equation is an expression that is used to show the relationship between two or more variables and numbers.

Given that:

I(dB) = 10log(I/I₀)

Where I is the intensity of sound in w/m², I₀ = 10⁻¹²

Given that I = 10³², hence:

I(dB) = 10log(10³²/10⁻¹²) = 440 dB

The intensity of a sound of 10³² w/m² is 440 decibels.
