According to the equation, the sign of x^2 is positive, so the curve should be a ‘smile’ shape, so A should be excluded.
Also, x^2-4=0
(x-2)(x+2)=0
x= 2 or -2
means that the curve should cut x-axis at point (-2,0) &(2,0), the best represented graph should be Option C

Simplify 12r + 5 + 3r - 5

Answers

Answer:

Step-by-step explanation:(12r+3r)+(5-5) = 15r + 0 = 15r

The simplified expression is 15r.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

12r + 5 + 3r - 5

Add like terms.

= 15r + 5 - 5

= 15r + 0

= 15r

Thus,

15r is the simplified expression.

. A container ship is overtaking an oil tanker on the way out of Harwich Harbor, and the first mate notices that if he starts walking from the front of the container ship when the two ships start overlapping, he reaches the back as the two ship separate. He walks at 3 km/hour. If the container ship is 100 m long, and travelling at 12 km/hour, how long is the oil tanker?

Answers

Answer:

The length of the oil tanker is 300 meters

Step-by-step explanation:

The given parameters are;

The speed with which the first mate is walking = 3 km/hour = 3,000 m/hour

The length of the container ship = 100 m

The speed with which the container ship is travelling = 12 km/hour

The time it takes the first mate to walk from the front to the back of the container, [tex]t_f[/tex] is therefore;

Time = Distance/Speed

[tex]t_f[/tex] = 100 m/(3000 m/hour) = 1/30 hour = 1/30 hour × 60 min/hour = 2 minutes

∴ [tex]t_f[/tex] the time it takes the first mate to walk from the front to the back of the container = 2 minutes

The resultant speed of the first mate relative to the ground = 12 km/hour - 3 km/hour = 9 km/hour

Given that the first mate starts at the front when the two ships starts overlapping and reaches the back as the two ships separate, we have;

The speed of the oil tanker relative to the container ship = The speed of the first mate relative to the ground

The speed of the oil tanker relative to the container ship = 9 km/hour

The length of the oil tanker = The speed of the oil tanker relative to the container ship × Time of observation of the first mate

∴ The length of the oil tanker = 9 km/hour × 2 minutes = 9 km/hour × 1/30 hours = 3/10 kilometers = 0.3 kilometers = 300 meters

The length of the oil tanker = 300 meters.

A rectangular prism is 3 units high, 2 units wide, and 5 units long. What is its surface area
insquare units? Explain or show your reasoning.

Answers

Answer:

62 square units

Step-by-step explanation:

Surface area of a rectangular prism = 2 ( wl + hl + hw)

Where,

w = width = 2 units

h = height = 3 units

l = length = 5 units

Surface area of a rectangular prism = 2 ( wl + hl + hw)

= 2 (2*5 + 3*5 + 3*2)

= 2 (10 + 15 + 6)

= 2 (31)

= 62 square units

Surface area of the rectangular prism = 62 square units

Answer:

HJ = 2.5

It is given that, J is between H and K. So,

HK = JH + JK

We have, HJ=5p JK=p and KH=3

So,

3 = 5p + p

3 = 6p

p = 1/2

The value of p is 1/2

How many times greater is 1 light year in scientific notation than a 1 astronomical unit?
Light year: 9.5 x 10^12 km
AU: 1.5 x 10^8 km

Answers

Answer:

1 light year \approx 6.02 \times 10^4  astronomical unit

Step-by-step explanation:

ratio

[tex]=\frac{9.5 \times 10^{12}}{1.5 \times 10^8}\\=\frac{19}{3} \times 10^{12-8}\\\approx 6.01666 \times 10^4 \\\approx 6.02 \times 10^4[/tex]

The number of times that 1 light year is greater than 1 astronomical unit in scientific notification is; 6.33 × 10⁴

We are given;

1 light year = 9.5 × 10^(12) km

1 astronomical unit = 1.5 × 10^(8) km

Thus to find out how many times greater 1 light year is than 1 astronomical unit in scientific notation, we will divide 1 light year by 1 astronomical unit.

This gives;

(9.5 × 10^(12))/(1.5 × 10^(8))

>> (9.5/1.5) × 10^(12 - 8)

>> 6.33 × 10⁴
