Length = 17 units

Width = 1 unit

Step-by-step explanation:

[tex]A = l * b[/tex]

[tex]17 = (2x+1) (x-7)\\17 = 2x^{2} -14x+x-7\\17 = 2x^{2} -13x-7\\2x^{2} -13x-7-17=0\\2x^{2} - 13x -24=0\\(2x+3) (x-8)=0\\x=-\frac{3}{2} or x=8\\[/tex]

but x cannot be negative because length and width cannot be negative;

Answer:

B. 72°

Step-by-step explanation:

Remember : Measure of inscribed angle = 1/2 × measure of intercepted arc.

Then

The measure of arc CD = 2 × m∠DBC

Answer: Line segments AB and DE are congruent.

Step-by-step explanation:

Given : Triangle ABC is congruent to triangle DEF .

We know that if two triangles are congruent then their corresponding sides and angles are congruent.

This property of congruent triangles are also known as CPCTC (corresponding parts of congruent triangles are congruent.)

Therefore,

m∠A=m∠D

m∠B=m∠E

m∠C=m∠F

AB=DE

BC=EF

AC=DF

From the given options the only right option is line segments AB and DE are congruent.

Answer:

Step-by-step explanation:

Answer: Line segments AB and DE are congruent.

A sine wave is also known as a sinusoid. The sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​ is 5Sin(16πx/3)+2.

A sine wave, also known as a sinusoid, is the graph of the sine function. Any curve that can be expressed in the form is referred to as a sinusoid. (A and B are both positive.) Sinusoids are the most generic version of the sine function.

Given the amplitude of the function is 5, the vertical shift is 3, and the period of 3/7. Therefore, the values of constants can be written as,

a = 5

b = (2π)/(3/7) = 14π/3

d = 2

Substituting the values in the sine function,

a sin b (x-c) + d

= 5 Sin(16π/3)(x-0) + 2

= 5 Sin(16πx/3) + 2

Hence, the sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​ is 5Sin(16πx/3)+2.

By the combined area of the triangles and the base. The total surface area of the regular pyramid would be 197.1 ft^2.

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

we need to find the areas of each triangle in the pyramid.

The area of base = 15.6

The area of each outer triangle = 1/2 x 9 x 12

 = 54

There are 3 triangle

3 x 54 = 162

The total area will become

162 + 35.1

= 197.1

Therefore, The total surface area of the regular pyramid = 197.1 ft^2

Answer: $5.00 is the range

Step-by-step explanation: Range is the largest number subtracted by the smallest, so $6 - $1 is $5.

For the part 1 volume is 32.768 dm³, for part 2 side length is  6 meters, and for part 3 the volume is 480 cubic cm.

It is defined as three-dimensional geometry that has six square faces and eight vertices.

We have

1) Side length = 3.2 dm

Volume = (3.2)³ = 32.768 dm³

2) Volume of cube = 216 cubic meters

a³ = 216

a = 6 meters

3) The dimensions for sewing box: 10 cm, 8 cm, and 6 cm

Volume = 10×8×6 = 480 cubic cm

Similarly, we can calculate the rest of the data.

Thus, for the part 1 volume is 32.768 dm³, for part 2 side length is  6 meters, and for part 3 the volume is 480 cubic cm.

Step-by-step explanation:

We know that the surface area is the sum of the area of the prism's faces.

It should be noted that the area of any face is equal to the area of its opposite face. Thus, we get the following equation for the surface area:

The equation that shows 3 less than the product of 4 and m is 3 < 4m

Formation of equation is a means of transforming statements into equations

The product of 4 and m is 4m

If 3 is less than the product of 4 and m, this is expressed as:

3 < 4m

Divide both sides by 4

3/4 < m

m > 3/4

Hence the equation that shows 3 less than the product of 4 and m is 3 < 4m
