Answer:

Part 1) [tex]y=-(1/4)x[/tex]

Part 2) [tex]y=-(3/5)x+2[/tex]

Part 3) [tex]y=(1/5)x-2[/tex]

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope

b is the y-coordinate of the y-intercept

Part 1) we have

[tex]20x+80y=0[/tex]

Simplify

Divide by 20 both sides

[tex]x+4y=0[/tex]

isolate the variable y

Subtract x both sides

[tex]4y=-x[/tex]

Divide by 4 both sides

[tex]y=-(1/4)x[/tex] ------> equation of the line into slope intercept form

[tex]m=-(1/4)[/tex]

[tex]b=0[/tex]

Part 2) we have

[tex]30x+50y-100=0[/tex]

Simplify

Divide by 10 both sides

[tex]3x+5y-10=0[/tex]

isolate the variable y

Subtract (3x-10) both sides

[tex]5y=-(3x-10)[/tex]

Divide by 5 both sides

[tex]y=-(3/5)x+2[/tex] ------> equation of the line into slope intercept form

[tex]m=-(3/5)[/tex]

[tex]b=2[/tex]

Part 3) we have

[tex]3x-15y-30=0[/tex]

Simplify

Divide by 3 both sides

[tex]x-5y-10=0[/tex]

isolate the variable y

Subtract (x-10) both sides

[tex]-5y=-(x-10)[/tex]

Divide by -5 both sides

[tex]y=(1/5)x-2[/tex] ------> equation of the line into slope intercept form

[tex]m=(1/5)[/tex]

Answer:

A. Parallel

Step-by-step explanation:

The given lines are

[tex]y=6x[/tex]

and

[tex]y=6x+2[/tex]

The slope of [tex]y=6x[/tex] is [tex]m_1=6[/tex].

The slope of [tex]y=6x+2[/tex] is [tex]m_2=6[/tex].

Since the two lines have the same slope, the two lines are parallel.

Answer:

The correct answer option is A. parallel.

Step-by-step explanation:

We are given the following two lines and we are to determine if they are parallel, perpendicular or none of them:

[tex]y = 6x[/tex] and [tex]y = 6x + 2[/tex]

According to the standard equation of a line, [tex]y=mx+c[/tex], the coefficient of x ([tex]m[/tex]) is the slope of the line.

Slope of [tex]y = 6x[/tex]  = 6

Slope of [tex]y = 6x + 2[/tex]  = 6

Since both the lines have same slope, therefore the two line are parallel.

Answer:

FIRST OPTION.

THIRD OPTION.

FOURTH OPTION.

FITH OPTION.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope, b the y-intercept and the exponent of x is always 1 or 0.

Solve for y from  the equations shown below:

[tex]5+2y=13\\2y=8\\y=4[/tex]

(In this linear function the slope is 0)

[tex]y-5=2(x-1)\\y=2x-2+5\\y=2x+3[/tex]

(It is a linear function)

[tex]\frac{y}{2}=x+7\\ y=2(x+7)\\y=2x+14[/tex]

 (It is a linear function)

Equation of the line whose slope is not defined:

Step-by-step explanation:

Rounding the nearest hundredth would be using the thousandths place to determine if the hundredths place must be rounded up or down. Because there is no visible thousandths place in 8.79, then it stays as 8.79. Because technically, there is an infinite number of zero's after the 9- and because 0 is less than 5, we leave the number as it is.

[tex]{(y + 2)}^{2} = 8(x - 4)[/tex]

EXPLANATION

The given parabola has equation of the form

[tex] {(y - k)}^{2} = 4p(x - h)[/tex]

where (h,k) is the vertex of the parabola.

The vertex of the given parabola is (4,-2).

and p is the distance between the foci and the vertex.

[tex] |p| = 2[/tex]

The parabola opens towards the positive x-axis, therefore p=2.

Hence the equation of the parabola is

Step-by-step explanation:

The distance between the sandbag and the target is 325 meters.

The distance between the sandbag and the target can be calculated by subtracting the distance of the sandbag from the balloon's height from the total distance between the balloon and the target. In this case, the balloon is 250 meters above the target and the sandbag is 75 meters below the balloon. So, the distance between the sandbag and the target is 250 + 75 = 325 meters.

Step-by-step explanation:

The center is at (-4.5,0) because -9/2 = -4.5

9 is the diameter in the above equation

Answer:

"circle; diameter of 9; center at (-4.5,0)"

Step-by-step explanation:

The polar equation of a circle centered on an axis, would take the forms:

1. Positive x-axis

r = (diameter) Cos θ

2. Positive y-axis

r = (diameter) Sin θ

3. Negative x-axis

r = - (diameter) Cos θ

4. Negative y-axis

r = - (diameter) Sin θ

As we see from the equation given, the diameter is 9 and it is centered n negative x-axis. And the center is Diameter divided by 2. So negative x axis has the center at (-9/2, 0) = (-4.5, 0)

The first choice is correct.

Answer: 19.13 yd²

Step-by-step explanation:

1. By definition,  you have that 1 square meter is equal to 1.19599 square yards. You can express it as following:

1 m²= 1.19599 yd²

2. Then, keeping the information above on mind, you can make the conversion from 16 m² to yd² as it is shown below:

[tex](16m^2)(\frac{1.19599yd^2}{1m^2})=19.13yd^2[/tex]

Therefore, you have that 16 m² is equivalent to 19.13 yd².

You can convert square meters to square yards by multiplying by 1.196. Therefore, 16 square meters is equivalent to 19.14 square yards.

You're asking about the conversion between square meters and square yards, which is used in measuring areas in mathematics and geometry. To do this conversion, we can use the conversion factor given in the references - 1 m² = 1.196 square yards.

Therefore, to find out how many square yards are equivalent to 16 square meters, we multiply 16 m² by 1.196 (the number of square yards in one square meter). Doing this math gives us an equivalent area of 19.136 square yards.

So, your 16-square meter area is roughly equivalent to 19.14 square yards, when rounded to two decimal places.

Answer:

It has 2.

Step-by-step explanation:

Since the numbers aren't zeroes they are automatically significant figures.

Answer:

2

Step-by-step explanation:

There are 2 digits needed to nail down the precise value of 12: a 1 in the tens place and a 2 in the ones place, giving it 2 significant figures.

For a few more examples, the number 1.23 would have 3 significant figures, the number 56.89 would have 4, and the number 1.00000 would have 1, as the trailing zeroes don't contribute anything to the number's actual value.

The half-life of the substance is calculated using the decay constant and is found to be 5.0 days when rounded to the nearest tenth.

To find the half-life of a substance, we use the decay formula N = [tex]N0e^{-kt}[/tex], where N is the remaining mass at time t, N0 is the initial mass, k is the decay constant, and t is the time in days. For a substance to reach its half-life, the remaining mass (N) will be half of the initial mass (N0).

Let's substitute the known values to find the half-life:

Initial mass N0 = 22 g

The decay constant k = 0.138

Half of the initial mass would be 11 g, so N = 11 g

Using the formula for half-life:

0.693 / k = t1/2

Substitute k = 0.138 into the equation:

t1/2 = 0.693 / 0.138

Calculate the half-life:

t1/2 = 5.0 days

Thus, we round to the nearest tenth to get the half-life as 5.0 days.

This is a maths problem involving the Pythagorean theorem, which involves calculating the hypotenuse of a right triangle. The squirrel, living in a tree 12 meters high and needing to glide to an acorn 16 meters away, will need to glide a distance of 20 meters.

This question is essentially asking you to calculate the hypotenuse in a right triangle, and the formula for this is rooted in the Pythagorean theorem. You're given the height of the tree (12 meters), which we can call 'a', and the distance from the base of the tree to the acorn (16 meters), which we can designate as 'b'.

The Pythagorean theorem goes as follows: a squared + b squared = c squared, where 'c' is the hypotenuse of the triangle, or in this case, the distance the flying squirrel needs to glide. So, we can plug in the numbers we have: (12²) + (16²) = c². This simplifies to 144 + 256 = c², or 400 = c².

To solve for 'c', we take the square root of both sides, and find that c = 20. Thus, the flying squirrel needs to glide 20 meters to reach the acorn.

The flying squirrel will have to glide 20 meters to reach the fallen acorn.

To find out how far the flying squirrel will have to glide to reach the fallen acorn, we can use the Pythagorean theorem because the squirrel will glide in a straight line from the tree to the acorn.

Let's denote the distance the squirrel glides as ( x ). According to the Pythagorean theorem, in a right triangle, the square of the hypotenuse (the distance the squirrel glides) is equal to the sum of the squares of the other two sides (the height of the tree and the horizontal distance to the acorn).

The given information:

- Height of the tree  =  12 meters

- Horizontal distance to the acorn  =  16 meters

Using the Pythagorean theorem, we have:

[tex]\[x^2 = (\text{Height})^2 + (\text{Distance to acorn})^2\]\[x^2 = 12^2 + 16^2\]\[x^2 = 144 + 256\]\[x^2 = 400\][/tex]

Taking the square root of both sides:

[tex]\[x = \sqrt{400}\]\[x = 20\][/tex]

So, the flying squirrel will have to glide 20 meters to reach the fallen acorn.
