What is an example of an x-intercept?

Answer:

28 m,  112 m

Step-by-step explanation:

x = length of short piece

4x = length of long piece

x + 4x = 140

5x = 140

x = 140/5 = 28

4x = 4(28) = 112

The outer perimeter of the figure will be 62.3 ft.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

The figure is shown in figure.

Now, The total outer perimeter is,

⇒ Outer perimeter of triangle = 12.2 ft + 6 ft

                                              = 18.6 ft

And, Outer perimeter of rectangle = 14 ft + 14 ft

                                                     = 28 ft

And, Outer perimeter of semicircle = πr

                                                      = 3.14 × 10 / 2

                                                      = 3.14 × 5 ft

                                                      = 15.70 ft

Thus, The total outer perimeter is = 18.6 ft + 28 ft + 15.70 ft

                                                    = 62.3 ft

y = -3x + 12   is the equation  for the line containing the side opposite the side containing the first two vertices.

Given coordinates:

(-3,4) ; (-2,1) ; and (2,6)

let us solve for the slope.

Since , parallel sides have the same slope.

m = y2-y1 / x2-x1

m = 1 - 4 / -2-(-3)

m = -3 / 1

m = -3

y = mx + b

Since , (2,6) is a point which passes through the line . Hence , it must satisfy the equation.

Therefore,

x + 2y = 3x + 4

2y = 3x + 4 - x

y = (2x + 4)/2

y = x + 2

Answer: y=x+2

Step-by-step explanation:

you subtract x on the left on both sides then you'll have 2y=2x+4 we have to get y by itself so divide it by 2 on both side and when you do that on the right you divide both 2x and 4 by 2 thus giving y=x+2

Solution of the equation is x = 3 ± i that is a complex number where 3 is the real part and i is the imaginary part.

The equation of two-degree polynomial having one variable is called quadratic equation.

The solution of a quadratic equation is either real or complex. We use quadratic equation formula for solution whenever we cannot expand, and factoring a given two-degree polynomial equation.

given equation, x² = 6x -10

                x²-6x +10 =0

This equation cannot be expanded so we need to write the formula for quadratic equation to solve it.

we know that standard form of a quadratic equation is given by

ax² + bx +c = 0

where a is the coefficient of x², b is the coefficient of x and c is the constant.

the solution of the equation is given by x = -b ± √ (b² - 4ac) / 2a

Now, the solution for the above equation is x = 6 ± √ (6² - 4×1×10) / 2×1

                                                                     x = 6 ± √ (36 -40) / 2

                                                                x = 6 ± √-4 / 2

                                                   as        √-4 = √-1 ×2

                                                            x = 6 ± 2 √-1 /2

Step-by-step explanation:

we need to use both equations for the volumes.

the only variables in them are r1 and r2.

when we say both results (volumes) are equal, that means we can create an equation with one formula on one side and the other formula on the other side.

and then we can easily transform the equation into "r1 = ..." or "r2 = ..."

and yes, your teacher made a mistake by hinting to solve for r1 in a. and b. it is r1 in a. and r2 in b.

a.

the goal here is an equation in the form

"r1 = ..."

that means r1 is a function of r2.

36×pi×r1² = 1/2 × 4/3 × pi × r2³ = 4/6 × pi × r2³ =

= 2/3 × pi × r2³

36 × r1² = 2/3 × r2³

r1² = (2/3 / 36) × r2³ = (1/(3×18)) × r2³ = 1/54 × r2³

r1 = sqrt(1/54 × r2³) = 1/3 × sqrt(1/6 × r2³)

b.

the goal here is

"r2 = ..."

again

36×pi×r1² = 2/3 × pi × r2³

36 × r1² = 2/3 × r2³

3×36 × r1² = 2 × r2³

3×18 × r1² = r2³

54 × r1² = r2³

[tex]r2 = \sqrt[3]{54 \times {r1}^{2} } = 3 \times \sqrt[3]{2 \times {r1}^{2} } [/tex]

c.

r2 is doubled.

so, we have to go back to our equation of a.

r1 = sqrt(1/54 × r2³).

when r2 is doubled, we get

r1 = sqrt(1/54 × (2×r2)³) = sqrt(1/54 × 8 × r2³) =

= sqrt(8) × sqrt(1/54 × r2³)

so, when r2 doubles, r1 has to grow by the factor of sqrt(8) to keep the equality intact.

The exponential function showing the relationship between y and t is y = 4800e^(0.0625t).

An exponential function is a function of the form f(x) = bx, where b is a positive real number and x is a real number. This type of function is commonly used to model the rate of growth or decay of a quantity over time. Exponential functions have the property that their derivatives (slope) are proportional to the value of the function itself. This property makes them useful for modeling phenomena with compound growth or decay, such as populations, interest rates, and radioactive decay.

In this equation, 4800 is the original principal, 0.0625 is the interest rate (6.25%) and t is the number of years since the start of the investment. This equation can be used to calculate the value of the investment after any number of years. For example, if t = 5, then y would equal 6,842.50. This means that after 5 years, the value of the investment would be 6,842.50.

Growth that is slower than the Nuttall Oak growth rate is h=5t.

An equation is a mathematical statement that expresses two values as being equal. It is the basic building block of algebra and can be used to solve for unknown values, or to show the relationships between two or more values. Equations use mathematical operators such as addition, subtraction, multiplication, and division, as well as symbols and numbers, to express relationships between values. An equation can be written in the form of an expression, a system of equations, or a single equation. In all cases, an equation requires both sides of the equation to be equal in order to be valid and have a solution.

This equation describes growth that is slower than the Nuttall Oak growth rate because it has a lower rate of growth of 5 feet per year. The Nuttall Oak grows 7 to 8 feet per year, so any equation with a growth rate lower than that would be slower.
