22 months of very hot weather. What is the percent increase in hot weather months from the
1980s to the 1990s? Round to the nearest percent.

Answer:

435

Step-by-step explanation:

Transformations are used to change the orientation of a function to a new function. The graph of [tex]f(x) = x^2[/tex] will have its parabola widened when it changes to [tex]g(x) = 3x^2[/tex]

Given that

[tex]f(x) = x^2[/tex]

If the new function is:

[tex]g(x) = 3x^2[/tex]

It means that f(x) has been vertically translated by a scale factor of 3.

The graph will be affected such that the parabola of [tex]f(x) = x^2[/tex] will become widen when the coefficient changes to 3 i.e. [tex]g(x) = 3x^2[/tex].

See attachment for the graph of f(x) and g(x)

Answer:

16 times

Step-by-step explanation:

We first have to find the total amount of crayons:

[tex]3+7+4+8+2+1=25[/tex]

That means that the box contains a total of 25 crayons. Of those 25 crayons, 7 are blue and 1 is orange. That means every time one crayon is chosen from the box, there is an 8 in 25 chance it will be blue or orange. We can represent that chance as a fraction: [tex]\frac{8}{25}[/tex]

That [tex]\frac{8}{25}[/tex] chance occurs each time ONE crayon is chosen, so if we want to know how many times blue or orange will be chosen after 50 times, we can multiply that chance by 50.

[tex]\frac{8}{25}*50=400/25[/tex]

Then you simplify the fraction:

[tex]\frac{400}{25}=16[/tex]

That means that if you pull crayons from the box 50 times, a blue or orange crayon will be likely drawn around 16 times.

Answer:

m = 5

p = 10

Step-by-step explanation:

Part A

The dashes on the lines mean that the lines are equal in length.

Therefore, IJ = IH and HK = KJ

So as IJ = IH

⇒ 10 = 2m

⇒ m = 10 ÷ 2

⇒ m = 5

Part B

The line IK is the bisector of angle I since IJ = IH and HK = KJ

Therefore, 2p - 5 = p + 5

subtract p from both sides:

⇒ 2p - 5 - p = p + 5 - p

⇒ p - 5 = 5

Add 5 to both sides:

⇒ p - 5 + 5 = 5 + 5

⇒ p = 10

Answer:

a) The differential equation for the velocity is given by

(dv/dt) = k(250 - v)

b) v(t) = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾

With units of km/h

Step-by-step explanation:

Acceleration, a ∝ (250 - v)

But acceleration is widely given as dv/dt

(dv/dt) ∝ (250 - v)

(dv/dt) = k(250 - v)

where k = constant of proportionality

(dv/dt) = k(250 - v)

b) (dv/dt) = k(250 - v)

dv/(250 - v) = k dt

∫ dv/(250 - v) = ∫ k dt

- In (250 - v) = kt + c (where c is the constant of integration)

v(0) = 0; meaning, at t = 0, v = 0

- In 250 = 0 + C

c = - In 250 = - 5.52

- In (250 - v) = kt - 5.52

In (250 - v) = 5.52 - kt

250 - v = e⁽⁵•⁵² ⁻ ᵏᵗ⁾

v = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾

With units of km/h

Step-by-step explanation:

The other factor of the polynomial [tex]\rm 3x^2-10x+8[/tex] is ( x - 2 )

It is given that the polynomial [tex]\rm 3x^2-10x+8[/tex] has a factor of  [tex]\rm (3x-4)[/tex].

It is required to find the other factor.

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

We have polynomial:

[tex]\rm = 3x^2-10x+8[/tex]

Now by using the factorization method:

[tex]\rm = 3x^2-10x+8\\\rm = 3x^2-6x-4x+8\\\rm =3x(x-2)-4(x-2)\\\rm = (x-2)(3x-4)[/tex]

Thus, the other factor of a given polynomial is ( x-2 )

Step-by-step explanation:

Just did the test. Wish you luck!!

The equation of line is y = ( 3/2 )x - 7 , where the slope is m = 3/2

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = 3/2

The y-intercept is b = -7

And , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

So , y = ( 3/2 )x - 7

Hence , the equation of line is y = ( 3/2 )x - 7
