The value of the unknown variable in the equation is -16

Linear equations are equations that has a leading degree of 1.

Given the linear equation below

-2 = 2 + v/4

We need to calculate for the unknown variable 'v'

Subtract 2 from both sides

-2-2 = v/4

-4 = v/4

Swap

v/4 = -4

Multiply both sides by 4

v = -4 8 4

v = -16

Hence the value of the unknown variable from the equation is -16.

The following statements is true: (c) if a trapezoid is also a kite, then it must be a parallelogram and others (a),(b) &(d) are false.

The following is a list of true and false statements regarding the relationship between kites, parallelograms, rhombi, and trapezoids:

(a) False. If a kite is also a parallelogram, it does not necessarily mean that it is a rhombus. A rhombus is a type of parallelogram with equal sides, while a kite is a specific type of quadrilateral with two pairs of equal-length sides.

(b) False. If a trapezoid is also a parallelogram, it does not necessarily mean that it is a rhombus. A rhombus is a type of parallelogram with equal sides, while a trapezoid is a type of quadrilateral with exactly one pair of parallel sides.

(c) True. If a trapezoid is also a kite, then it must be a parallelogram. A kite is a specific type of quadrilateral with two pairs of equal-length sides, which automatically makes it a parallelogram.

(d) False. If a rhombus is also a trapezoid, it does not necessarily mean that it is a kite. A kite is a specific type of quadrilateral with two pairs of equal-length sides, while a rhombus is a type of parallelogram with equal sides.

In conclusion, it's important to understand the definitions and properties of each type of quadrilateral to determine if a statement about their relationship is true or false.

Above that the statement indicates just simple interest equals $157.92.

With only the coordination mechanism and a fixed interest rate, simple yearly interest is interest connected to borrowing. Compounding, wherein borrowers are obligated to pay tax on the principal as well as interest that rises over a number of pay periods, is not included. Simple interest is calculated by multiplying the original by calendar, rate of return and time period.

Due to it,

P = $1305.17

R = 11/10%

T = 11 months

Now, Simple Interest = P*R*T/100

Simple Interest = 1305.17 * 1.1 * 11/100

Simple Interest = 157.92

Therefore, Simple Interest is $157.92

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 3 , then

y = - 3x + c

the line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

Answer:

x = 8

Step-by-step explanation:

To solve the equation x(x - 2) = 48 for x, we can first expand the left side:

x^2 - 2x = 48

Next, we'll add 2x to both sides to isolate x^2:

x^2 = 48 + 2x

Then, we'll subtract 2x from both sides:

x^2 - 2x = 48

Now we have a quadratic equation that we can solve for x using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = -2, and c = 48. Plugging these values into the formula:

x = (-(-2) ± √((-2)^2 - 4(1)(48))) / 2(1)

x = (2 ± √(4 + 192)) / 2

x = (2 ± √196) / 2

x = (2 ± 14) / 2

So the two solutions are x = (2 + 14) / 2 = 8 and x = (2 - 14) / 2 = -6.

Keep in mind that x cannot be negative in this context as it represents a measurement. Therefore, x = 8 is the only solution that has a meaningful value in this context.

Step-by-step explanation:

x(x-2)=48

Remove the parentheses

x²-2x=48

Move the constant to the left

x²- 2x - 48=0

Rewrite the expression

x² + 6x - 8x - 48 = 0

Factor the expressions

x(x+6) - 8(x+6) = 0

Separate into possible cases

(x+6) (x-8)=0

x + 6 = 0

x - 8 = 0

x = - 6 or x = 8

Step-by-step explanation:

3540/3820 = 93%

so 7% decline

if linearly = every year decline 7%

so back in 1990, 3 years ago, the population was

p° = 3820/(1-7%)^3 =3820/.8=4749

so from 1990

p = 4749 * (1-7%)^t

2009 is 16 years from 1993

so p = 3820 * (1-7%)^16 =1196

Answer:

  A)  P(t) = 3820 -70t

  B)  2700

Step-by-step explanation:

You want a linear equation for the moose population that changed from 3820 in 1993 to 3540 in 1997, and you want the predicted population in 2009.

The slope of the linear function can be found from ...

  m = (p2 -p1)/(t2 -t1)

If we let t represent years after 1993, then this is ...

  m = (3540 -3820)/(4 -0) = -280/4 = -70

P(t) = 3820 -70t . . . . . . . . population is 3820 when t=0, 70 less each year

2009 is 16 years after 1993, so we want P(16):

  P(16) = 3820 -70·16 = 3820 -1120

  P(16) = 2700

The population is predicted to be 2700 in 2009.

The simplified form of the expression (mp)⁶ is equal to m⁶×p⁶.

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents is only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

The given expression is (mp)⁶.

We know, 2²×2² = 2⁴ but 2²×3² = (2×3)² = 6².

where A = amount accrued (principal + interest)
P = initial deposit

r = annual interest rate as a decimal

n = number of times compounded annually

t = number of years

Given
P = 4000
r = 6/100 = 0.06
n = 4 times a year
t = 5 years

[tex]A = 4000\left( 1 + \dfrac{0.06}{4}\right)^{4\cdot 5}\\\\A = 4000 ( 1+ 0.015)^{20}\\\\A = 4000 (1.015)^{20}\\\\A = \$5,387.42[/tex]

        only    90

Answer:

$12,581.53

Step-by-step explanation:

The balance of an account after having interest compounded annually can be represented using the equation:

[tex]A = P(1 + r)^{t}[/tex]

where [tex]A[/tex] is the final balance, [tex]P[/tex] is the principal (starting amount), [tex]r[/tex] is the rate of interest, and [tex]t[/tex] is the number of years that interest is applied.

We can plug the given values into this equation and solve for [tex]A[/tex].

[tex]P = \$10,000[/tex]     [tex]r = 4.7\%[/tex]     [tex]t = 5[/tex]

[tex]A = 10,000(1 + 4.7\%)^{5}[/tex]

[tex]A \approx \$12,581.53[/tex]

So, Sally's balance in an account that had $10,000 before being compounded for 5 years at an interest rate of 4.7% is $12,581.53.

The required critical points of f is (0, 0) and the function f does not have a local maximum nor local minimum.

The critical points of a function f are the points in the domain where the partial derivatives of f are equal to 0 or are undefined. To find the critical points of f, we can find the partial derivatives of f with respect to x and y, and set them equal to 0:

df/dx = -2x

df/dy = 2y

Setting df/dx equal to 0, we have:

-2x = 0

So, x = 0.

Setting df/dy equal to 0, we have:

2y = 0

So, y = 0.

Thus, the only critical point of f is (0, 0).

To show that f does not have any local maximums nor any local minimums at the critical point (0, 0), we can check the second partial derivatives of f at this point:

d²f/dx² = -2

d²f/dy² = 2

d²f/dxdy = 0

At (0, 0), d²f/dx² is negative and d²f/dy² is positive, which indicates that f is a saddle point at (0, 0). This means that f does not have a local maximum nor a local minimum at (0, 0).

Yes, this is true. Congruence refers to the idea that two geometric figures are identical in size and shape. Translations, rotations, and reflections are rigid motions that preserve distances and angles, meaning that corresponding lines, line segments, and angles in the figures will remain congruent after the transformation.

Answer:

Step-by-step explanation:

Given that cos(60°) = 1/2, we can use trigonometric identities to find the sine, cosine, and tangent of 30°:

Sine of 30°:

sin(30°) = √[1 - cos^2(30°)] = √[1 - (cos(60°)/2)^2] = √[1 - 1/4] = √3/2.

Cosine of 30°:

cos(30°) = √[1 - sin^2(30°)] = √[1 - (√3/2)^2] = √[1 - 3/4] = √1/4.

Tangent of 30°:

tan(30°) = sin(30°) / cos(30°) = (√3/2) / (√1/4) = √3.

So, the sine of 30° is √3/2, the cosine of 30° is √1/4, and the tangent of 30° is √3.
