Answer:

O x = - 6 or x = 2

Step-by-step explanation:

x² + 4x - 4 - 8 = 0

x² + 4x - 12 = 0

x² + 6x - 2x - 12 = 0

x(x + 6)x - 2(x + 6) = 0

(x + 6) (x - 2) = 0

x + 6 = 0 or x - 2 = 0

x = - 6 or x = 2

Thus, x = - 6 or x = 2

~q → ~p   statement is logically equivalent to conditional statement p→q.

A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

We need to find the equivalent statement of p→q.

This statement implies that if p is true then q is true

p is the premise and q the conclusion

The logically equivalent statement to p → q is ~q → ~p.

This can be proven using the contrapositive of the original statement, which states that ~q → ~p is logically equivalent to p → q.

The contrapositive of this statement is

~q → ~p   this statement implies that not q implies not p

Hence, ~q → ~p   statement is logically equivalent to conditional statement p→q.

In the decimal numeral system, each numeral is represented by a combination of digits from 0 to 9.

The decimal numeral system is a base-10 system, which means it uses ten digits (0 to 9) to represent numbers. Each numeral in this system is a combination of these digits. The position of each digit in a number represents its value based on powers of 10. For example, the numeral "123" represents the value of (1 * 10^2) + (2 * 10^1) + (3 * 10^0), which is equal to 100 + 20 + 3 = 123.

To represent larger numbers, additional digits are used. For instance, the numeral "1,234" represents (1 * 10^3) + (2 * 10^2) + (3 * 10^1) + (4 * 10^0), which is equal to 1,000 + 200 + 30 + 4 = 1,234.

In the decimal numeral system, the digits to the left of the decimal point represent whole numbers, while the digits to the right represent fractions or decimals. For example, the numeral "3.14" represents the whole number 3 and the fraction 14/100, which is equivalent to the decimal 0.14.

In summary, the decimal numeral system uses the digits 0 to 9 to represent numbers, with each digit's position indicating its value based on powers of 10. This system allows for the representation of both whole numbers and fractions or decimals.

Ms. Miller spent $49 on 160 pieces of gum and candy for a math class party. With a 10-pack of gum costing $2.50 and a pack of fifteen candies costing $6, we need to determine the number of packs of gum and candy she purchased.

Let's assume Ms. Miller purchased 'x' packs of gum and 'y' packs of candy. The cost of 'x' packs of gum is 2.5x dollars, and the cost of 'y' packs of candy is 6y dollars. The total spent by Ms. Miller is $49.

We can set up two equations based on the given information:

Equation 1: 2.5x + 6y = 49 (cost equation)

Equation 2: 10x + 15y = 160 (quantity equation)

To solve this system of equations, we can use substitution or elimination. By solving the equations, we find that the number of packs of gum, x, is approximately -15, which doesn't make sense in this context. Therefore, there may be an error or missing information in the problem statement.

Answer:

(-2, -6)

Step-by-step explanation:

Given the simultaneous equation

3x-y=0 ... 1

2x+y=-10 ... 2

Add both equations to eliminate y

3x + 2x = 0 - 10

5x = -10

x = -10/5

x = -2

Substitute x = -2 into 1

3(-2)- y = 0

-6 - y = 0

-y = 0+ 6

-y = 6

y = -6

Hence the coordinate (x, y) is (-2, -6)

the unit normal vector to the curve with vector equation \vec r \, (t) =<1^t,\ln(4/t^2), \, \ln(e/(t^4)) > r (t)=<1 t ,ln(4/t 2 ),ln(e/(t 4 ))> at the point where t=2t=2 is \vec n = <0,0,-1>

A unit normal vector is a normal vector with magnitude 1, and it points in the direction that is perpendicular to the tangent to the curve at a given point.

To determine the unit normal vector to a curve, it's important to find the tangent first and then find the normal. In this case, we're looking for the unit normal vector to the curve with the vector equation \vec r (t) =<1^t,\ln(4/t^2), \ln(e/(t^4)) > at the point where t = 2.

To find the unit normal vector to the curve with the vector equation \vec r (t) =<1^t,\ln(4/t^2), \ln(e/(t^4)) > at the point where t = 2, it is necessary to find the tangent to the curve and then find the normal. This is a crucial step in understanding the geometry of curves in 3D space.

To find the tangent to the curve, we'll differentiate the vector equation with respect to t and evaluate it at t = 2. The derivative of \vec r (t) is given by:

d\vec r/dt = <1, -2t^-3, -4e^-t^-4>

So the tangent to the curve at t = 2 is:

d\vec r/dt = <1, -2(2)^-3, -4e^-2^-4> = <1, 1.5, -1.648721>

Next, we'll find the normal to the tangent by taking the cross product of the tangent with a fixed vector, for example, the unit vector i = <1,0,0>. The cross product of two vectors results in a vector that is perpendicular to both of them.

The cross product of the tangent and the unit vector i is given by:

\vec T x \vec i = <1, 1.5, -1.648721> x <1,0,0> = <0,0,-1.5>

Since the magnitude of the normal is not 1, we'll normalize it by dividing it by its magnitude:

\vec n = \vec T x \vec i / ||\vec T x \vec i|| = <0,0,-1.5> / ||<0,0,-1.5>|| = <0,0,-1>

So the unit normal vector to the curve with the vector equation \vec r (t) =<1^t,\ln(4/t^2), \ln(e/(t^4)) > at the point where t = 2 is given by:

\vec n = <0,0,-1>

This is the unit normal vector that points in the direction that is perpendicular to the tangent to the curve at t = 2. The magnitude of 1 ensures that it's a unit vector and the direction points towards the normal direction.

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months
