y = 2

substitute x = 2 into the equation

2(2)² = y³ ⇒ y³ = 8 ⇒ y = ∛8 = 2

y is also 2.

2x^2 = 8

2^3 = 8

Hannah is 2 times her sister’s age. The sum of their ages is no more than 18 years. 1) Write an inequality that can be used to r
svetoff [14.1K]

Answer:

1) x+2x\leq 18.

2) 6 years

Step-by-step explanation:

Let Hanna's sister be x years old.


Then Hanna will be 2x years old.


The sum of their ages will be x+2x years.

The statement "no more than 18" means the sum of their ages is less than or equal to 18.

The required inequality is;

x+2x\leq 18.

2)

The inequality we just found is


x+2x\leq18.

We simplify to get;

3x\leq 18.

we divide both sides by 3 to get;

x\leq 6.

Therefore the oldest age Hannah's sister can be is 6 years

The width of the rectangle is 2 more than the length. The area of the rectangle is 63 square inches. How long is the width?
wariber [46]

Answer:

9 inches

Step-by-step explanation:

Area of rectangle= length ×width

Let the length of the rectangle be x inches.

Width of rectangle= (x +2) inches

<em>since</em><em> </em><em>the</em><em> </em><em>width</em><em> </em><em>is</em><em> </em><em>2</em><em> </em><em>more</em><em> </em><em>than</em><em> </em><em>the</em><em> </em><em>length</em><em>.</em>

63= x(x+2)

63= x(x) +2x

<em>Bringing</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>,</em>

x² +2x -63= 0

(x +9)(x-7) = 0 (<em>factorise</em><em>)</em>

x+9= 0 or x-7= 0

x= -9 or x= 7

(reject)

width of rectangle

= 7+2

= 9 inches

*We reject x= -9 since the length of the rectangle cannot be a negative number.

Which function h(x) results when g(x) is translated startfraction 7 pi over 8 endfraction units right and 1 unit down? h (x) = 2
jonny [76]

The required function h(x) is  h (x) = 2 cosine (x + StartFraction 11 pi Over 8 EndFraction) minus 3. Option d is correct.

Function g(x) =  2cos (x + π/2) - 2

What are trigonometric equations?

Equation which includes trigonometric operators eg sin, cos.. etc.. In algebraic processes.

Here, the phase of the curve is increase by 7π/8.

So the phase = π/2 + 7π/8

                      = 11 π/8

And Shift of curve along y axis is by -1.

So, the total shift = -2-1

                             = -3

⇒ h(x) = 2cos (x + 11π/8) - 3

Thus, the function h(x) results when g(x) is translated.h (x) = 2 cosine (x + StartFraction 11 pi Over 8 EndFraction) minus

If numerous large random samples or repetitions of the same size are taken from a population, the frequency curve made from prop
Evgen [1.6K]

Using the Central Limit Theorem, the shape of the frequency curve will be approximately normal.

<h3>What does the Central Limit Theorem state?</h3>

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1 - p)}{n}}, as long as np \geq 10 and n(1 - p) \geq 10.

Hence, the shape of the frequency curve will be approximately normal.
