Solve y3 = −125.

please please help

Answer: y=-0.5x-8

Step-by-step explanation:

Choose two points on the line: (0,-8) and (-6,-5)

Hence,

x₁=0   x₂=-6   y₁=-8   y₂=-5

[tex]\displaystyle\\The\ slope=\frac{y_2-y_1}{x_2-x_1}\\\\The\ slope=\frac{-5-(-8)}{-6-0} \\\\The\ slope=\frac{-5+8}{-6} \\\\The\ slope=\frac{3}{(3)(-2)}\\\\The\ slope=\frac{1}{-2} \\\\The\ slope=-\frac{1}{2}\\\\The\ slope=-0.5[/tex]

[tex]y=kx+b\\k=the\ slope=-0.5\\(0,-8) \ hence,\\-8=-0,5*0+b\\-8=0+b\\-8=b\\Thus,\\y=-0.5x-8[/tex]

The highest point of this ramp will be at 30 inches.

It is given that Wheelchair ramps have at least a 12 -inch run for each rise of 1 inch and Max length for a ramp is 30 feet.

We have to find the highest point of ramp in inches.

What will be the value of 10 feet in inches ?

As we know that 1 feet = 12 inches , the value of 10 feet in inches will be ; 10 × 12 inches or 120 inches.

As per the question ;

Wheelchair ramps have at least a 12 inch run for each rise of 1 inch.

Max length for a ramp = 30 feet

or

Max length for a ramp = 30 × 12 inches

or

Answer:

x = 6

Step-by-step explanation:

- 12x - 17 = - 89 ( add 17 to both sides )

- 12x = - 72 ( divide both sides by - 12 )

x = [tex]\frac{-72}{-12}[/tex] = 6

The value of x when y = 4 is 0. 25

From the information given, we have that;

This is expressed as;

x ∝ 1/ y²

x = y/y²

Let's substitute the value of y as 4 into the equation;

x = 4 / 4²

Find the square

x = 4 / 16

Find the ratio

x = 1/ 4

x = 0. 25

Answer: 125.7 degrees

Step-by-step explanation:

supplementary angles add up to 180 degrees.

angle 1 + angle 2 = 180

54.3+angle 2=180.0

54.3-54.3+angle 2=180.0-54.3

angle 2=180.0-54.3

Answer:

x = 5

Step-by-step explanation:

3(x + 7) + 4 = 40 ( subtract 4 from both sides )

3(x + 7) = 36 ( divide both sides by 3 )

x + 7 = 12 ( subtract 7 from both sides )

x = 5

As a check

substitute x = 5 into the left side of the equation and if the value obtained is equal to the right side (40) then it is a solution

3(5 + 7) + 4

= 3(12) + 4

= 36 + 4

= 40

left side = right side

then x = 5 is the solution to the equation

The given series is an arithmetic series and its sum is 36.4

The summation or sigma notation is used to express long summation into a single formula.

The series, given in a summation notation, is:

     [tex]\sum\limits^{10}_{n=4} {(0.8n-0.4)}[/tex]

The formula inside the sum notation represent the nth term, a(n).

Let evaluate the terms for some n, starts from n = 4 as indicated by the lower limit of the summation notation:

a(4) = 0.8 (4) - 0.4 = 2.8

a(5) = 0.8 (5) - 0.4 = 3.6

a(6) = 0.8 (6) - 0.4 = 4.4

This form a new arithmetic series, with the first term, let say f(1) =2.8 and common difference, d = 0.8.

The number of terms in this new geometric series is given by the upper and lower limit of the summation notation:

number of terms = 10 - 4 + 1 = 7

Use the sum formula for an arithmetic series,

S(n) = n/2 [2.f(1) + (n - 1) . d]

Substitute n = 7, f(1) = 2.8, and d = 0.8 into the formula:

S(7) = 7/2 [2. (2.8) + (7 - 1) . (0.8)]

S(7) = 36.4

The equation of line is:

y = (5/2) x - 11

Given,

Points (x₁, y₁) = (-12, -6) and (x₂, y₂) = (8, 9)

We can find the slope using the equation for slope

m = (y₂ - y₁) / (x₂ - x₁)

   = (9 -(-6)) / (8-(-12))

   = (9+6) / (8 + 12)

    = 15/20 = 3/4

We know the slope and a point, so we can use point slope form to make an equation

y-y₁ = m(x-x₁)

y - (-6) = 3/4 (x-(-12))

Distribute

y+6 = 3/4x – 3/4 × 2

y+6 = 3/4x - 3/2

Add -6 to each side

y + 6 -6 = 3/4x - (3/2)-6

y = 3/4x - (-9/2)

y = 3/4x + 9/2

The equation of the line is y = -3x/5 + 1 that passes through (5, −2), and is perpendicular to y = (5/3)x - 3.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line passes through (5, −2) and is perpendicular to y = (5/3)x - 3

The slope of the line y = (5/3)x - 3

m = 5/3

The slope of the line perpendicular to the above line:

M = -3/5

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The equation of the line

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

y = -3x/5 + 1

Thus, the equation of the line is y = -3x/5 + 1 that passes through (5, −2), and is perpendicular to y = (5/3)x - 3.

The compound inequality that describes Tammy's test score x 85 < x < 92 and Tammy's test score is between 85 and 92

The given parameters are

Sam's test score is between 100 and 107

This means that

100 < Sam's score < 107

From the question, we have:

Tammy scored about 15 fewer points.

This means that

Tammy = Sam - 15

So, we have

Sam = Tammy + 15

Where

Tammy = x

This gives

Sam = x + 15

So, we have

100 < x + 15 < 107

Subtract 15 from the sides of the inequality

So, we have

85 < x < 92

This means that the compound inequality that describes Tammy's test score x 85 < x < 92

The measure of the vertex angle is 92°

Here,

The triangle is isosceles and one base angle of an isosceles triangle has a measure of 44°

We have to find the measure of the vertex angle.

What is Isosceles triangle?

A triangle is said to be isosceles if there is any two corresponding sides are equal and there angle are equal.

Now,

The triangle is isosceles triangle.

Hence, there corresponding sides and there angles are equal.

So, Both base angles of a triangle are equal.

And, Sum of angles of a triangle are 180°

Let the measure of the vertex angle is x°

Step-by-step explanation:

The triangle inside the circle is an isosceles triangle, since two of its sides are the radius of the the circle (and therefore equal in length).

Therefore, its two base angles are 27°.

A tangent is a straight line that touches a circle at only one point.

The tangent of a circle is always perpendicular to the radius.

[tex]\implies x + 27^{\circ} = 90^{\circ}[/tex]

If the tower is located at the origin, the equation of its circular area of coverage is [tex]x^{2} +y^{2} = 225[/tex]

A circle is a closed curve that is drawn from a fixed point. This point is called the center. All points on the curve are equidistant from this center point.

The equation of a circle with center at (h, k) and radius r is given by:
