Answer:

y intercept is -6 put your first point on that y intercept

Step-by-step explanation:

from -6  rise 3 and run 1 (to the right )

whats that point ?  (0,2)

from  that point 2.... run 1 ( to the right and up 3) that will take from x4 to y6

(0,2) (4,6) Two points

y2 -y1 = 6

x2-x1  =2

6/2 simplified is 3/1

Make sense?

Answer:

10

Step-by-step explanation:

296/26 = 11.3846153846

Now round it to the nearest tenth = 11.40

round to the nearest whole number = 11

To the nearest zero digit = 10

Answer:

Step-by-step explanation:

296 .Here ten's place is 9 >= 5 . So, add 1 to hundred's place

296 = 300

26. Here units place is 6 >= 5 . So, add 1 to ten's place

26 = 30

[tex]\frac{296}{26}=\frac{300}{30}=10[/tex]

Answer:

Jay will need 2 and 1/3 pounds of turkey.

Step-by-step explanation:

Since Jay uses 1/3 per sandwich and is making 7, multiply 7 by 1/3.

That gets you 7/3s

Convert it into a mixed number.

3 goes into 7 twice, with one third left over.

So, Jay needs 2 1/3.

hope this helped!

Given Length of Cuboid = 12cm

Given Breadth of Cuboid = 9cm

Given height of Cuboid = 8cm

Total Surface area of cuboid = 2(lb + bh + hl)

where, l stands for legth of the cuboid, b stands for breadth of the cuboid and h stands for height of the cuboid.

Put the given values of l,b and h in the formula

=> Total surface area of cuboid = 2((12×9)+(9×8)+(8×12))

=> 2(108 + 72 + 96)

=> 2(180 + 96)

=> 2 × 276

=> 552 sq. cm is the total surface area of cuboid

Answer:

b) 0.0228

Step-by-step explanation:

We use the z score formula when given random number of samples =

z = (x-μ)/σ/√n where

x is the raw score = $3.5 million

μ is the population mean = $3.26 million

σ is the population standard deviation = $ 1.2 million

n = random number samples = 100

Hence,

z = 3.5 - 32.6/1.2/√100

z = 3.5 - 32.6/1.2/10

z = 3.5 - 3.26/0.12

z =2

Probability value from Z-Table:

P(x<3.5) = 0.97725

P(x>3.5) = 1 - P(x<3.5)

P(x>3.5) = 1 - 0.97725

P(x > 3.5) = 0.02275

Approximately ≈ 0.02278

The approximate probability that the mean salary of the 100 players exceeded $3.5 million is 0.02278

Answer:

x ≈ 11.5, y ≈ 3.4

Step-by-step explanation:

Th rectangular components of the vector are

x = r cosθ

y = r sinθ

where r is the magnitude and θ is the angle between x- axis and vector

Here r = 12 and θ = 90° - 73.3° = 16.7° , then

x = 12 cos16.7° ≈ 11.5 m ( to 1 dec. place )

y = 12 sin16.7° ≈ 3.4 m ( to 1 dec. place )

Answer:

Step-by-step explanation:

Given that:

mass m = 100 g = 0.1 kg

Length of the spring = 5 cm = 0.05 m

The set in motion from the equilibrium position u(0) = 0

The set in motion from its equilibrium position with a downward velocity u'(0) = 50 cm/s = 0.5 m/s

The spring constant (k) = [tex]\dfrac{0.1 \times 9.8}{0.05}[/tex]

The equation of the system is expressed as:

[tex]\dfrac{1}{10} u'' + \dfrac{98}{5} u =0[/tex]

By estimating the characteristics equation, we have r = ± 14[tex]i[/tex]

Thus; the general solution is:

[tex]u(t) = c_1cos \ 14t + c_2 sin 14 \ t[/tex]

By applying the initial condition:

u(0) = 0

⇒ 0 = [tex]c_1[/tex]

∴

[tex]\dfrac{du}{dt} = ( - c_1 \ sin 14 t )\times 14 +14c_2 \ cos 14 t[/tex]

u'(0) = 0.5

0.5 = 14 × c₂

c₂ = 0.5/14

c₂ = 1/28

∴

[tex]\mathbf{u(t) = \dfrac{1}{28} sin 14 t}[/tex]

Equating u(t) = 0, we have t = π/14sec as the time when the mass first returns to its equilibrium position.

We want to compare two prefixes, kilo and tera, and see why one seems to be more important than the other.

The prefix "kilo" is used for thousands, while the prefix "tera" is used for trillions.

Now if you go to your day-to-day life, you will see that the thousands appear a lot more than the trillions.

For example, is more common to walk one or two kilometers than one terameter.

Or also is more common to buy a kilogram of potatoes than one teragram of potatoes.

This is mainly why kilo is more important (actually is more used, I wouldn't say that is more important) than tera.
