Answer:

31 feets

Step-by-step explanation:

Given that :

Telephone shadow Ts = 12 feets

Man's height, Mh= 6 feets

Man's shadow, Ms = 2 feets 4 inches

Height of telephone, Th =?

Recall :

1 foot = 12 inches

x foot = 4 inches

12x = 4

x = 4/12 = 1/3 inches

Hence, man's shadow = 2 1/3 feets =

Using cross multiplication :

Mh / Ms = Th / Ts

6 / 7/3 = Th / 12

6 / 2.33333 = Th / 12

12 * 6 = 2.33333 * Th

72 = 2.33333 Th

Th = 72 / 2.333333

Th = 30.85

Height of telephone pole = 31 feets

Answer:

Increasing: [tex](\infty, 0)\cup (1,\infty)[/tex]

Decreasing: [tex](0, 1)[/tex]

Concave Up: [tex](0, \infty)[/tex]

Concave Down: [tex](-\infty, 1)[/tex]

Step-by-step explanation:

Increasing intervals are intervals where the function is approaching positive infinity (upwards). Decreasing intervals are intervals where the function is approaching negative infinity (downwards). Concavity refers to intervals that resemble a parabola either opening upwards (Concave Up) or opening downwards (Concave Down).

Answer:

the two points be

(0,0) and (1,-3)

slope [m]=[-3-0]/[1-0]=-3

constant rate is-3.

Step-by-step explanation:

exterior angle

-> (4x + 6)° = x + 102°

3x = 102° - 6°

3x = 96°

x = 32°

4x + 6°= 4×32° + 6° = 128 + 6 = 134°

just divide the total weight by 2 and add 2.6. after adding 2.6 you subtract that weight from the total.

Answer:

20%

Step-by-step explanation:

Probability is always expressed as a part of a whole, thereby in fractions or percentages. From the statistics gathered, it said that 80% of the time, the plane arrives right on schedule in El Centro. That means that the probability of NOT arriving on time is the other portion, which is 20%. The answer is 20%.

Step-by-step explanation:

p(B)={3,4,5,6}

p(AnB)={3,4}

now,

LHS=RHS. proved.

Answer:

not sure about answer for 2 but here is the answer for question 1...

Step-by-step explanation:

answer for 1.

Volume = bridth × height

volume = 1.5cm × 8cm

volume = 12cm

Answer:

Angle 1 = 105

Angle 2 = 75

Step-by-step explanation:

Angle 2 and angle 75 are corresponding angles.

Corresponding angles are equal.

So,

Angle 2 = 75

Angle 1 and angle 2 are linear pair angles.

Angle 1 + Angle 2 = 180

Angle 1 + 75 = 180

Angle 1 = 180 - 75

Angle 1 = 105

Answer:

100.48

Step-by-step explanation:

Surface area of a cylinder = [tex]2\pi r^2+2\pi rh[/tex]

Where r = radius and h = height

We are given the diameter ( 4 cm ) and the height ( 6cm )

To convert diameter to radius we simply divide by 2 ( because radius = half the length of the diameter )

4 / 2 = 2 Thus, r = 2

Now we plug in the values of the radius and height into the surface area of a cylinder formula ( note we must use 3.14 for π as the question says to. not doing so can result in a wrong answer )

[tex]SA=2(3.14)(2^2)+2(3.14)(2)(6)\\2^2=4\\4*3.14=12.56\\12.56*2=25.12\\\\2*3.14=6.28\\6.28*2=12.56\\12.56*6=75.36\\\\75.36+25.12=100.48\\SA=100.48cm^2[/tex]

Answer:

Answer:

A

Step-by-step explanation:

A is the only one that makes sense and if you write it out is is -6 degrees. A negative integer is a normal whole number but is negative. Hope this Helps!

Step-by-step explanation:

volume cylinder 1 =

3.14× 3²× 5 = 3.14×45 = 141.3 in³

volume cylinder 2 =

3.14× 5²× 2 = 3.14× 50= 157 in³

the volume difference between cylinder 1 & 2 =

157 - 141.3 = 15.7 in³

Answer:

20.5

Step-by-step explanation:

By the Triangle Midsegment Theorem, the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side. Therefore, (1/2)FH ≡ IH, (1/2)HG ≡ HJ. Knowing that IJ = 8 gives you the presidence to solve for the perimeter.

Answer:

[tex]2\pi \times r[/tex]

1. 2×3.14×80

=502.4 m

4. 90 pound on Earth weighs 34 pounds on Mars.

If it weighs 135 pounds on earth, it will weigh x pounds on Mars

=90×=135×34

=90x=4590

=x=4590÷90

x=51 pounds

So therefore it weighs 51 pounds on Mars.

in question 4 you have to cross multiply

Answer:

27 ft

Step-by-step explanation:

Im assuming you need to find the area of the triangle based on the information you are given...

In that case, plug the values into the formula for tirangle area:

[tex]A=\frac{bh}{2}[/tex]

To get: [tex]A=\frac{(6)(9)}{2}[/tex]

Solve to get: 27

Given:

In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and [tex]m\angle BCD=30^\circ[/tex].

To find:

The [tex]m\angle AOB[/tex].

Solution:

If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.

We have, DC is parallel to BA and BC is the transversal line.

[tex]\angle OBA\cong \angle BCD[/tex]        [Alternate interior angles]

[tex]m\angle OBA=m\angle BCD[/tex]

[tex]m\angle OBA=30^\circ[/tex]

In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.

We know that base angles of an isosceles triangle are congruent.

[tex]\angle OAB\cong \angle OBA[/tex]      [Base angles of an isosceles triangle]

[tex]m\angle OAB=m\angle OBA[/tex]

[tex]m\angle OAB=30^\circ[/tex]

In triangle AOB,

[tex]m\angle OAB+m\angle OBA+m\angle AOB=180^\circ[/tex]

[tex]30^\circ+30^\circ+m\angle AOB=180^\circ[/tex]

[tex]60^\circ+m\angle AOB=180^\circ[/tex]

[tex]m\angle AOB=180^\circ-60^\circ[/tex]

[tex]m\angle AOB=120^\circ[/tex]

Therefore, the measure of angle AOB is 120 degrees.

Answer: x = - 6

y = 7

Step-by-step explanation:

Let 2x -5y = -47 be eq. 1

And 6x -5y = -71 be eq. 2

By substrate of 1 - 2:

2x-5y-6x+5y = -47+71

so -4x=24 and x= -6

Substitute x in any eq.

2(-6) - 5y = -47

-5y = -47 +12

-5y = -35 so y= 7

Step-by-step explanation:

Answer:

[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]

Step-by-step explanation:

Relation between acceleration, velocity and position:

The velocity function is the integral of the acceleration function.

The position function is the integral of the velocity function.

Acceleration:

As given by the problem, the acceleration function is [tex]a(t) = 2t + 5[/tex]

Velocity:

[tex]v(t) = \int a(t) dt = \int (2t+5) dt = \frac{2t^2}{2} + 5t + K = t^2 + 5t + K[/tex]

In which K is the constant of integration, which is the initial velocity. So K = -3 and:

[tex]v(t) = t^2 + 5t - 3[/tex]

Position:

[tex]s(t) = \int v(t) dt = \int (t^2 + 5t - 3) = \frac{t^3}{3} + \frac{5t^2}{2} - 3t + K[/tex]

In which K, the constant of integration, is the initial position. Since it is 12:

[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]

Answer:

x = 20

Step-by-step explanation:

x/10 = 2

Multiply each side by 10

x/10 * 10 = 2*10

x = 20
