what equation passes (-4,-1) and is parallel to y=2x+14?

Answer: -25y/216x

Step-by-step explanation: - 25y / 216x

Answer:

(-30x^2/y^2)^5

Step-by-step explanation:

First, we can simplify the exponent in the first term by using the property that (a^m)^n = a^(m⋅n). This property tells us that we can calculate the exponent of the first term by multiplying the exponent of the base by the exponent of the power, which gives us (-3)⋅(-3) = 9. This means that the first term can be rewritten as (2x ⋅ -3/y)^9.

Next, we can simplify the second term by calculating its exponent in the same way, which gives us (-2)⋅(2) = -4. This means that the second term can be rewritten as (-5x/y)^-4.

We can then combine the two terms by using the property that (a^m)⋅(b^n) = (a⋅b)^(m+n). This property tells us that we can calculate the exponent of the combined terms by adding the exponents of the individual terms, which gives us 9 + (-4) = 5. This means that the entire expression can be rewritten as (2x ⋅ -3/y)^9 ⋅ (-5x/y)^-4 = (2x⋅-3/y⋅-5x/y)^5.

Finally, we can simplify the base of the combined terms by multiplying the factors together, which gives us (2x⋅-3/y⋅-5x/y) = -30x^2/y^2. This means that the entire expression can be rewritten as (-30x^2/y^2)^5.

Both conditions must be met in order to ride: being at least five years old and being at least 36 inches tall. expression evaluates to true if a person can ride - (Age >= 5) && (Height > 36)

In order for a person to ride, two conditions must be true: they must be at least 5 years old and taller than 36 inches. In order to evaluate whether a person can ride, we can use the expression (Age >= 5) && (Height > 36). This expression evaluates to true if both conditions are true; if either one is false, then the expression will evaluate to false. For example, if a person is 4 years old and 40 inches tall, then the expression will evaluate to false because the first condition is false. On the other hand, if a person is 5 years old and 40 inches tall, then the expression will evaluate to true because both conditions are true.

Step-by-step explanation:

it is 03. in a polynomial the hightest power of varibale shows the degree of it.

Answer:

y= 4x + 0

Step-by-step explanation:

The perimeter y of a square with side length x can be described by the equation y = 4x + 0.

The perimeter of a square is equal to four times the length of one side. If the side length of a square is 1 centimeter, then the perimeter of the square is 4 centimeters. We can use this information to write an equation in point-slope form to describe the relationship between the side length of a square and its perimeter.

Point-slope form is a way of writing the equation of a line when we know the slope of the line and the coordinates of a point on the line. In this case, the slope of the line is 4, since the perimeter of a square is four times the length of one side. The coordinates of a point on the line are (1, 4), since the side length of a square is 1 centimeter and the perimeter of the square is 4 centimeters.

We can use this information to write the equation of the line in point-slope form. The equation of a line in point-slope form is given by the following equation:

y - y1 = m(x - x1)

where y is the y-coordinate of a point on the line, y1 is the y-coordinate of a known point on the line, m is the slope of the line, and x is the x-coordinate of a point on the line.

In this case, we can substitute the values we know into the equation above to get:

y - 4 = 4(x - 1)

This simplifies to:

y = 4x + 0

Therefore, the equation in point-slope form that describes the relationship between the side length x of a square and its perimeter y is y = 4x + 0.

This equation tells us that for any square, the perimeter is four times the side length plus zero. For example, if the side length of a square is 5 centimeters, then the perimeter is 4 x 5 + 0 = 20 centimeters. If the side length of a square is 10 centimeters, then the perimeter is 4 x 10 + 0 = 40 centimeters.

In summary, the perimeter y of a square with side length x can be described by the equation y = 4x + 0.

The expression √45 × √10 is simplified using the property of square roots to give an equivalent choice of 15√2

The product √45 × √10 can be simplified by using the property of square roots that states √(a × b) = √a × √b.

By application of this property, we have that:

√45 × √10 = √(45 × 10).

To simplify further, we find that 45 and 10 have a common factor of 5, and thus,

45 × 10 = 5 × (9 × 10)

45 × 10 = 5 × 90.

Now, we can rewrite √(45 × 10) as √(5 × 90).

Using the same property again, we obtain √5 × √90. Finally, we recognize that 90 can be factored into 9 × 10.

Thus;

√45 × √10 = √(2 × 9 × 25)

√45 × √10 = √2 × √225

√45 × √10 = √2 × 15

√45 × √10 = 15√2

The number of remaining green and yellow pins is 14 pins and 21 pins.

A proportion is a mathematical calculation that compares two numbers. According to proportion, two sets of given numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

The fraction of green pins present in the bag is 3/7. Then, the fraction of yellow pins present in the bag is 4/7.

When Yaqub picks up the green pin and gives it to his sister, the new fraction of green and yellow pins are 2/5 and 3/5.

Let x be the number of pins remaining in the bag after 1 pin less. This is written as,

[tex]\begin{aligned}\frac{3}{7}x-1 &= \frac{2}{5}x\\\frac{3}{7}x-\frac{2}{5}x&=1\\x&=35\end{aligned}[/tex]

Answer:

b = - [tex]\frac{a}{a-1}[/tex]

Step-by-step explanation:

a = [tex]\frac{b}{1+b}[/tex] ( multiply both sides by 1 + b to clear the fraction )

a(1 + b) = b ← distribute parenthesis on left side

a + ab = b ( subtract b from both sides )

a + ab - b = 0 ( subtract a from both sides )

ab - b = - a ← factor out b from each term on left side

b(a - 1) = - a ( divide both sides by a - 1 )

b = - [tex]\frac{a}{a-1}[/tex]

The measure of one angle is 1.56° and another angle is 88.64°.

Complementary angles are two angles whose combined angle is 90 degrees.

Let's consider the smaller angle as A and the larger angle as B.

Given that the two angles are complementary, then their sum is A+B = 90°.

The angle B is 20° more than and 44 times angle A. Then B = 44A+20°. Substituting this equation in the A+B = 90° equation, we get,

A+44A+20° = 90°

45A = 90°-20°

A = 70°/45

A = 1.56°

Substitute A = 1.56°in B = 44A+20°, we get,

B = 44(1.56°)+20°

B = 88.64°

1. The total amount (future value) Marcus had at the end of the second year of investing $5,000 at 2.5% compounded annually was $5,253.13.

2. The minimum number of years Marcus must leave the $5,253.13 to be more than $10,000 is 11.3 years.

The future value is the compounded present value at an interest rate.

The future value can be derived from an online finance calculator as follows:

With the future value so determined, we can then compute the minimum time in years required for it to reach more than $10,000 at the simple interest rate.

Initial investment = $5,000

Interest rate = 2.5% compounded annually

Investment period = 2 years

N (# of periods) = 2

I/Y (Interest per year) = 2.5%

PV (Present Value) = $5,000

PMT (Periodic Payment) = $0

Results:

FV = $5,253.13

Total Interest = $253.13

Principal = $5,253.13

Interest rate = 8% per annum

Future amount = $10,000

Time to reach the future amount = (Future Value/Principal - 1) ÷ Interest rate

= ($10,000/$5,253.13 - 1) ÷ 0.08

Water is dripping from an inverted cone.

height , h = 12 cm

diameter , d = 12 cm

so, radius, r = 6 cm

rate , dV/dt = - 1 cm³/sec

At any point, the portion of the cone that is filled will have the ratio of radius/height = 6/12 = 1/2. Put another way, h = 2r.

we have to calculate the rate is the water level decreasing , dh/dt when radius of the water's surface is r = 2 cm .

Volume of cone , V = 1/3 π (r)²h = 1/3π (h/2)²h

plugging all known values,

differentiating with respect to h we get,

dV/dh = 1/3(3h²)π/4 , h = 12

= 1/12(3× 4r²)π ( from r = 2 cm)

= 4π cm²

but we have required, dh/dt = dV/dt × dh/dV

To establish the given identity, we need to first multiply the left side of the equation and write it as the difference of two squares. This can be done by using the difference of squares formula, which states that the difference of two squares can be written as the product of the square of the sum and the square of the difference.

The left side of the given equation can be written as:

(csc0+1)(csc0-1)

We can then apply the difference of squares formula to this expression to get:

(csc0+1)(csc0-1) = (csc0+1)(csc0-1)

Now, we can see that this expression is equivalent to cot 0 using the Pythagorean Identity. This identity states that the sum of the squares of the cosecant and cotangent of an angle is equal to 1. In this case, since (csc0+1)(csc0-1) = cot 0, we can use the Pythagorean Identity to rewrite the left side of the equation as (csc0^2 + cot0^2) = 1, which is equivalent to cot 0.

Therefore, the given identity is established using the Pythagorean Identity. This means that the correct answer is C. Pythagorean Identity.
