All the real numbers x which satisfy the given inequality x²<4 , in  interval form is (-2, 2).

As given in the question,

Given inequality is given by :

x²< 4

Simplify the given inequality  x² < 4 to get all the real numbers x we have,

x² < 4

⇒ x² - 4 < 0

⇒ x² - 2² < 0

Apply a² - b² = ( a - b ) ( a + b ) we get,

⇒ ( x - 2 ) ( x + 2 ) < 0

⇒ x ∈ ( -2 , 2 ) as less than symbol represent open interval.

Therefore, all the real numbers x which satisfy the given inequality x²<4 , in  interval form is (-2, 2).

The complete question is :

Find all real numbers x such that x^2 < 4. Give your answer in interval notation.

A quantity that represents the degree of power to which a particular number or expression is to be increased, commonly displayed as a raised symbol next to the number or word is termed as exponent.

Solution:

According to the rule of Exponent

[tex](a^{b} )^{c} = a^{b*c}[/tex]

Using the same rule;

[tex](w^{8})^{8} = w^{8*8}[/tex]

The particle will move to the right for t > a .

In the question ,

it is given that ,

a particle moves along the x axis , such that at any time t ≥ 0 ,

its position is given by the equation

x(t) = 12(a−t)²  ,

where a is = positive constant

to find value of the particle moves right ,

we differentiate x(t) , with respect to "x" .

x'(t) = 12×2(a - t)×(-1)

v(t) = -24(a-t)        ..... because x'(t) = v(t)

for particle to move right , v(t) > 0 .

-24(a-t) > 0

dividing both sides by "-24" , we get

a - t < 0

a < t

t > a .

Therefore , The particle will move to the right for t > a .

The given question is incomplete , the complete question is

Answer:

  $7

Step-by-step explanation:

You want to know the cost of each friend's meal if 5 friends spend $41 on their food, which includes a $6 delivery charge.

For 'a' friends spending 'x' on each meal, the total cost is ...

  6 + ax = 41

Solving for x, we have ...

  ax = 41 -6 = 35

  x = 35/a

When the number of friends is a = 5, the cost of a meal is ...

  x = 35/5 = 7

The cost of each friend's mean when the number of friends is 5 is $7.

Reasoning is not accurate because we cannot take 79.4 and 0.815 has cluster estimates of 8.

Given:

A student estimated the sum 7.95 + 8.11 + 78.5 + 8.05 + 79.4 + 0.815 as: All the numbers begin with a 7 or 8, so use cluster estimation. 8 + 8 + 80 + 8 + 80 + 0.8 = 184.8  

7.95 + 8.11 + 78.5 + 8.05 + 79.4 + 0.815

8 + 8 + 80 + 8 + 80+ 0.8 = 184.8  

Cluster estimation is  used to estimate sums and products when the numbers being  added or multiplied cluster near/ close in value to a single number.

Here 79.4 does not cluster around 8

And 0.815 does not cluster around 8  

Therefore reasoning is not accurate because we cannot take 79.4 and 0.815 has cluster estimates of 8.

The system of equations for determining the dollar amount of  phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200

A commission is defined as the compensation paid to a person or entity based on the sale of a product. It is calculated on a percentage basis

Given:

Phone sales commission = 4%

Computer sales commission = 5%

Total commission = $129

Let Sc and Sp represent the dollar amount of phone sales and computer sales respectively

If Houa had $600 more in computer sales than in phone sales, the equation can be written as:

Sc = Sp + 600

Since Houa earns a 4% commission on phone sales and a 5% commission on computer sales, and a total commission of $129. Thus, the equation for the commission can be written as:

0.05Sc + 0.04Sp = 1200

Note:  5% = 5/100 = 0.05 and  4% = 4/100 = 0.04

Therefore, the system of equations for determining phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200

a. The value of 9.9² × 1.79 is 175.44.

b. The value of ✓97.5 + 1.96 is 11.83

An exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

In this case, the value of 9.9² × 1.79 will be:

= 9.9² × 1.79

= 98.01 × 1.79

= 175.44

The value of ✓97.5 + 1.96 will be:

= ✓97.5 + 1.96

this seems tough, but,  remember the formulas  ,  point slope  and how to find M ( slope)  and this gets much easier.

let's use the point-slope formula to get the  slope-intercept formula

from my memory,  which you can also memorize

y-y1=m(x-x1)   (point-slope formula)

we are given the slope m = -2

and we're given a point  P(x1,y1)  as  ( -1,-4)

plug this info into our plug and play formula  :P

y-(-4) = (-2)(x-(-1))    : note all the careful attention to minus signs

y+4 = (-2)(x+1)

y+4 = -2x -2

y = -2x -2 -4

y =-2x-6   (slope-intercept formula  y = mx +b)

The value of Y = 17.77 when X = 3, and the value of Y = 16 when X = 3

The equation which represents "Y varies inversely as the square of X"  can be written as:

Y = k/X² where "k" is a constant.

Substitute the values of  X=4 and Y= 10 in the variation equation and solve for k:

⇒ 10 = k/(4)²

⇒ 10 = k/16

⇒ k = 160

The variation equation :

⇒ Y = 160/X²

Substitute the values of X = 3 in the above equation and solve for Y:

⇒ Y = 160/(3)²

⇒ Y = 160/9

⇒ Y = 17.77

Thus, the value of Y = 17.77 when X = 3

The equation which represents "Y Varies inversely as X"  can be written as:

Y = k/X where "k" is a constant.

Substitute the values of Y=8 and X=6 in the variation equation and solve for k:

⇒ 8 = k/(6)

⇒ k = 48

The variation equation :

⇒ Y = 48/X

Substitute the values of X = 3 in the above equation and solve for Y:

⇒ Y = 48/(3)

⇒ Y = 16

Thus, the value of Y = 16 when X = 3

Step-by-step explanation:

Both the length and width of the rectangle are approximately 31.62 m each.

The Area of a rectangle is calculated by multiplying the length by the width.

A = L x W

We have given that area of rectangle is 1,000 m²

1000 = W× L => W = 1000/L ---(1)

The circumference of rectangle is twice the sum of the dimensions. That is,

P = 2L + 2(1000/L)

Now, it is provided that perimeter is minimum so, we differentiate perimeter with respect to L then put first order derivative equal to zero.

dP/dL = 2 + 2000(-1/L²) = 0

=> 2-2000/L²=0

=>2000/L²=2

=> L²=2000/2

=> L²= 1000

=> L= 31.622

putting value of L in (1) we get , W= 31.622m

Therefore the length and width of the rectangle are both approximately 31.622m .

The coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3 are [-3.5, -2].

In this exercise, line ratio would be used to determine the coordinates of the point on the directed line segment that partitions the segment into a ratio of 5 to 3.

Mathematically, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Given the following parameters:

Substituting the given parameters into the line ratio formula, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(5(-2) + 3(-6))/(5 + 3)],  [(5(-8) + 3(8))/(5 + 3)]

P(x, y) = [(-10 + (-18))/(5 + 3)],  [(-40 + 3(8))/(5 + 3)]

P(x, y) = [(-10 - 18)/(8)],  [(-40 + 24)/(8)]

P(x, y) = [(-28)/(8)],  [(-16)/(8)]
