Answer:

The shape of the cross-section is a square

Step-by-step explanation:

Given

[tex]r =2[/tex]

[tex]h = 4[/tex]

See attachment

Required

The shape of the cross-section

From the attachment, we can see that when the cylinder is cut vertically, the shape formed is a quadrilateral of equal opposite sides.

The dimension of the shape is: the height of the cylinder and the diameter of the base circle

From the given parameters, we have the radius and the height to be:

[tex]r =2[/tex]

[tex]h = 4[/tex]

The diameter (d) is:

[tex]d = 2 * r[/tex]

[tex]d = 2 * 2[/tex]

[tex]d = 4[/tex]

So, the dimension is:

[tex]h = 4[/tex] and [tex]d = 4[/tex]

Since the height and the diameter have the same lengths, then the shape is a square.

Answer:

[tex]\boxed {\boxed {\sf 250 \ people}}[/tex]

Step-by-step explanation:

Let's set up a proportion using the following setup.

[tex]\frac {buses}{people}=\frac {buses}{people}[/tex]

We know 30 buses can carry 1,500 people.

[tex]\frac {30 \ buses}{1500 \ people}=\frac {buses}{people}[/tex]

We don't know how many people 5 buses can carry, so we say 5 buses carry x people.

[tex]\frac {30 \ buses}{1500 \ people}=\frac {5 \ buses}{x \ people}[/tex]

[tex]\frac {30 }{1500 }=\frac {5 }{x }[/tex]

Cross multiply. Multiply the numerator of the first fraction by the second fraction's denominator. Then, multiply the first denominator by the second numerator.

[tex]30*x=1500*5\\30x=7500[/tex]

Solve for x. It is being multiplied by 30. The inverse of multiplication is division. Divide both sides by 30.

[tex]30x/30=7500\\x=250[/tex]

5 buses can carry 250 people.

Answer:

65

Step-by-step explanation:

<S = <t

x + 50 = 3x + 20

2x = 30, x = 15

. <t = <v

3x + 20 = 45 + 20 =  65

Answer:

b.  65 degrees.

Step-by-step explanation:

m < RST = m < STU (alternate angles), so

x + 50 = 3x + 20

50 - 20 = 3x - x

2x = 30

x = 15.

Now m < RVT = m < RST  ( opposite sides of a parallelogram are equal).

So m < RVT = x + 50 = 15 + 50 = 65.

Answer:

The measure of Angle 2 would also be 57 degrees

Step-by-step explanation:

Answer:

A. m(arc BC) = 16°

B. m(arc BAC) = 344°

Step-by-step explanation:

From the picture attached,

AB is the diameter of the circle.

Since, measure of an arc is always same as the central angle of arc.

Therefore, m(arc AC) = m(∠ADC) = 164°

m(arc AB) = 180°

m(arc BC) = 360° - m(arc AB) + m(arc AC)

                = 360° - (180° + 164°)

                = 360° - 344°

                = 16°

m(arc BAC) = m(arc AB) + m(arc AC)

                   = 180° + 164°

                   = 344°

310°+O2=360°

O2=360°-310°

O2=2D1(centre theorem)

50°=2D1

D1=25°

2. D1=B3=25°(tan chord theorem)

3. B2+B3=A=60°(tan chord theorem)

B1+B2+B3=90°(Radius perpendicular Tangent)

B1+60°=90°

B1=90°-60°

Answer:

height:6

if the base is a square that means all the side lengths are equivalent so it would be 8 for side lengths, and the volume is 128. plug it in with the formula to get 6

The height of a pyramid is 8cm

Supposing that:

The length of the sides of the square base the pyramid has = b units

The height of the considered square based pyramid = h units,

Then, its volume is given by: [tex]V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3[/tex]

Given;

The volume of pyramid= 128cm3

Length of side of square base= 8cm

Now,

128=1/3 x 8x8xh

128= 64/3 xh

h= 128x3/64

h=8

Therefore, the height with the volume 128cm3 will be 8cm

Answer:

74.054 rounded to the nearest tenth is equivalent to 74.1

Step-by-step explanation:

Since you're rounding 74.054 to the nearest tenth, you need to focus on the hundredths place. If the number on the hundredths place is greater than or equal to 5, then you round up. If not, keep the number in the tenths place the same. In this case, 5 is in the hundredths place, which means you need to round the 0 in the tenths place up by 1. So 74.054 rounded to the nearest tenths is equivalent to 74.1.

Answer:

{−2, 0, 4}

Step-by-step explanation:

[tex]\displaystyle 6x^3 - 12x^2 - 48x \\ 6x[x^2 - 2x - 8] \\ 6x[x + 2][x - 4] \\ \\ 0, 4, -2 = x[/tex]

I am joyous to assist you at any time.

The roots of the cubic polynomial 6x³ - 12x² - 48x  = 0 are  -2, 0 and 4.

The degree of a cubic polynomial is 3. Degree of a polynomial is the highest power of the variable in that polynomial. In cubic polynomial, the variable [x] has the highest power of 3 (x³).

Given is the following cubic polynomial -

6x³ - 12x² - 48x  = 0

In order to find the roots of this cubic equation, we will plot its graph. The number of y - intercepts [coordinates where the graph cuts the x axis] will give us the roots or zeroes of the polynomials. The degree of a cubic polynomial is [3], therefore the number of zeroes of this cubic polynomial will be 3. Refer to the graph attached, it can be seen that the graph cuts the x-axis at three points -

x = -2, 0, 4

Which are the roots of this cubic polynomial 6x³ - 12x² - 48x  = 0.

Therefore, the roots of the cubic polynomial 6x³ - 12x² - 48x  = 0 are  -2, 0 and 4.

A is the right answer of your question but....

I m little bit doubtful about that

==========================================================

Explanation:

When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.

In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.

In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.

If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.
