The mass of the sun is about 2x10^27 metric tons or 2x10^30 kilograms. How many kilograms are in one metric ton

Final answer:

The 400 meter dash is the longer distance by 2.336 meters.

Explanation:

In order to determine which is the longer distance, we need to convert both the 440 yards and the 400 meters into the same unit of measurement. Since 1 yard is equal to 0.9144 meters, we can convert the 440 yards into meters by multiplying it by 0.9144:

440 yards * 0.9144 meters/yard = 402.336 meters

Therefore, the 400 meter dash is the longer distance by 2.336 meters.

To simplify expressions with negative exponents, rewrite the negative exponent as the reciprocal of the base raised to the positive exponent.

When simplifying expressions with negative exponents, you can use the rule that states a negative exponent can be rewritten as the reciprocal of the base raised to the positive exponent. For example, x^-3 can be rewritten as 1/x^3. You can use this rule with negative exponents in the numerator or denominator, as well as with negative exponents inside parentheses. Here’s an example:

8x^-2 / (2y^-3) = 8 / (2y^3x^2)

Final answer:

To find out how many weights the personal trainer can purchase, subtract the cost of the weight bench from the budget and divide the remaining amount by the cost of each weight. The personal trainer can purchase 15 weights within the given budget.

Explanation:

To find out how many weights the personal trainer can purchase, we need to subtract the cost of the weight bench from the budget and divide the remaining amount by the cost of each weight.

Step 1: Subtract the cost of the weight bench ($500) from the budget ($860): $860 - $500 = $360.

Step 2: Divide the remaining amount ($360) by the cost of each weight ($24): $360 ÷ $24 = 15.

The personal trainer can purchase 15 weights within the given budget.

This budgeting approach demonstrates a systematic way for the personal trainer to allocate funds effectively, ensuring that both essential equipment and a sufficient quantity of weights can be acquired. By following these steps, the trainer maximizes the utility of the available budget, making informed decisions to support an efficient and well-equipped training environment.

A cylinder is a three-dimensional figure that has a radius and a height.

The volume of a cylinder is given as:

Volume = π r²h

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume = 3.14 x 2 x 2 x 5 = 62.8 cubic cm

We have,

Aluminum cans:

Height = 6 inches

Diameter = 2 inches

Radius = diameter/2 = 2 / 2 = 1 inches

The aluminum can is in the shape of a cylinder.

The volume of the aluminum can:

= πr²h

= 22/7 x 1 x 1 x 6

= 18.84 cubic inches

The amount of soda in a full can is 18.84 cubic inches.

Thus,

The amount of soda in a full can is 18.84 cubic inches.

in this problem we have

[tex]V(\frac{5}{7})[/tex]

that means

The radius of the rubber ball is [tex]\frac{5}{7}\ ft[/tex]

and

The volume of the rubber ball is [tex]V(\frac{5}{7})\ ft^{3}[/tex]

therefore

the answer is the option B

Answer:  The zeroes of the given polynomial f(x) are

[tex]x=1-\sqrt{\dfrac{23}{8}},~~~x=1+\sqrt{\dfrac{23}{8}}.[/tex]

Step-by-step explanation:  We are given to find the zeroes of the quadratic function below:

[tex]f(x)=8x^2-16x-15.[/tex]

To find the zeroes, we must find the roots of the following equation

[tex]f(x)=0\\\\\Rightarrow 8x^2-16x-15=0~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex].

We know that the roots of the quadratic equation of the form [tex]ax^2+bx+c=0,~a\neq 0[/tex] is given by

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}.[/tex]

In the given quadratic equation , a = 8, b = -16  and  c = - 15.

Therefore, the roots of the equation are

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\\\\Rightarrow x=\dfrac{-(-16)\pm\sqrt{(-16)^2-4\times 8\times (-15)}}{2\times 8}\\\\\\\Rightarrow x=\dfrac{16\pm\sqrt{256+480}}{16}\\\\\\\Rightarrow x=\dfrac{16\pm\sqrt{786}}{16}\\\\\\\Rightarrow x=\dfrac{16\pm4\sqrt{46}}{16}\\\\\\\Rightarrow x=\dfrac{4\pm\sqrt{46}}{4}\\\\\\\Rightarrow x=1\pm\sqrt{\dfrac{46}{16}}\\\\\\\Rightarrow x=1\pm\sqrt{\dfrac{23}{8}}\\\\\\\Rightarrow x=1-\sqrt{\dfrac{23}{8}},~~~x=1+\sqrt{\dfrac{23}{8}}.[/tex]

Thus, the zeroes of the given polynomial f(x) are

[tex]x=1-\sqrt{\dfrac{23}{8}},~~~x=1+\sqrt{\dfrac{23}{8}}.[/tex]

Option (C) is correct.

The zeroes of the given polynomial f(x) = 8x^2-16x-15 are x = 1 + [tex]\sqrt{23}[/tex] / 8 and x = 1 -[tex]\sqrt{23}[/tex] / 8 Thus, Option C is correct.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given to find the zeroes of the quadratic function f(x) = 8x^2 - 16x-15

f(x) = [tex]8x^2-16x-15[/tex] = 0

We know that the roots of the quadratic equation ax² + bx + c = 0 is

x = -b ± [tex]\sqrt{b^2 - 4ac}[/tex] / 2a

In the given quadratic equation , a = 8, b = -16  and  c = - 15.

So,

x = -b ± [tex]\sqrt{b^2 - 4ac}[/tex] / 2a

x = -(-16) ± [tex]\sqrt{(-16)^2 - 4(8)(-15)}[/tex] / 2(8)

x = 16  ± [tex]\sqrt{256+ 480}[/tex] / 16

x = 16  ± [tex]\sqrt{786}[/tex] / 16

x = 4  ± [tex]\sqrt{46}[/tex] / 4

x = 1 ± [tex]\sqrt{23}[/tex] / 8

Thus, the zeroes of the given polynomial f(x) are

x = 1 + [tex]\sqrt{23}[/tex] / 8 and x = 1 -[tex]\sqrt{23}[/tex] / 8. Option C is correct.

The problem can be solved using the Pythagorean theorem. The lengths of the legs of the triangle are calculated as 15 inches for the shorter leg and 21 inches for the longer leg.

In solving this mathematical problem, we can employ the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides- This theorem is normally written as a² + b² = c². We can let one leg of the right triangle be 'a', the other leg be 'a+6' (since one leg is 6 inches longer than the other), and the hypotenuse is 25 inches. From the equation, we substitute a and b with the values and get:

a² + (a + 6)² = 25²

This equation is solved to get the lengths of the legs. Solving results in 'a' being 15 inches (the shorter leg) and 'a+6' equals to 21 inches (the longer leg).
