Tell Whether Each System Of Equations Has No Solution Or ,infinitely Many Solutions.

Answers

Answer 1

Answer:

See below.

Step-by-step explanation:

x + 2 = x + 2 ⇒ Infinitely Many Solutions

3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions

x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution

Answer:  HKJ = 100

Step-by-step explanation

In this problem we need to use the property of a inscribed angle:

The inscribed angle is a point in the circle that has endpoints also in the circle. The value of the inscribed angle is half the value of the arc formed by the endpoints.

So, If the arc FJ is 84°, we have that the angle in point G isi 84/2 = 42°

Answer:

6.9

Step-by-step explanation:

Arc Length Formula: 2rπdata/360

First find data:

In this case, data is the length of arc AB

Arc AB is the central angle: 165 degrees

Substitute radius and data into the formula

2(2.40)(165)π/360

This form(792/360π) is not acceptable since the question is asking for the answer in decimal form. Multiply pi.

Make sure to use the pi symbol, not 3.14.

792/360π

The diagram shows a right-angled triangle. 37° 15 cm cm What is the value of h? Give your answer correct to 1 decimal place.

Answers

[tex]tan = \frac{opp}{adj} [/tex]

[tex] \tan(37) = \frac{opp}{15} [/tex]

[tex]h = 15 \tan(37) [/tex]

[tex]h = 11.3 \: cm[/tex]

Answer:

h ≈ 11.3 cm

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tan37° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{15}[/tex] ( multiply both sides by 15 )

15 × tan37° = h , that is

h ≈ 11. 3 cm ( to 1 dec. place )

Students drop a 2 kg object from rest out a window that has a

height of 10 m during a lab experiment. The students time the

object to hit the ground and measure 1.2 s. Calculate the

difference between the PE at the top and the KE at the bottom.

a. greater than 75 J

b. less than 25 J

c. between 25 J & 50 J

d. between 50 J & 75 J

Answers

Answer:

a. greater than 75 J

Step-by-step explanation:

Potential Energy at the top = mgh

Mass m = 2kg

g = 9.8m/s^2

height h  = 10m

Potential Energy at the top = 2 * 10 * 9.8

Potential Energy at the top = 196Joules

The object is not moving at the bottom, hence the KE of the body at the bottom is 0Joules

difference between the PE at the top and the KE at the bottom = 196 - 0 = 196Joules

Hence the difference between the PE at the top and the KE at the bottom is greater than 75Joules

A Cylinder has a radius of 10 feet and a height of 11.4 feet what is the approximate volume of the cylinder?

Answers

Answer:

3579.6 [tex]ft^{3}[/tex]

Step-by-step explanation:

First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.

I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.

Step-by-step explanation:

area of circle = r×r×π

area of circle × height = volume

10 × 10 × π = 314.16

314.16 × 11.4 = 3581.42

Calculate the area and perimeter of the polygon.

Answers

Answer:

a) P = 24.2 units

b) A = 13.9 square units

Step-by-step explanation:

Perimeter = [tex]\sqrt{10}[/tex]+[tex]\sqrt{10}[/tex] + 4[tex]\sqrt{5}[/tex] + 4[tex]\sqrt{5}[/tex]

P = 2[tex]\sqrt{10}[/tex] + 8[tex]\sqrt{5}[/tex] which is approx 24.2 units

To find area you must find the height which can be done using the Pythagorean Theorem (we can do this for the small triangle on the left):

([tex]\sqrt{5}[/tex]²) + h² = ([tex]\sqrt{10}[/tex]²)

5 + h² = 10

h² = 5

h = [tex]\sqrt{5}[/tex]

A = bh

A = [tex]\sqrt{5}[/tex] (4 + [tex]\sqrt{5}[/tex])

A = 4[tex]\sqrt{5}[/tex] + 5 which is approx 13.9 square units
