Which equation represents the solution of x^3 = 72?
A line that passes through the points (x, 4) and (6, -1) has a slope of 56. what value of x will yield the given slope?
The value of x that yields a slope of 56 is 6.09
How to determine the value of x?The given parameters are:
Slope = 56Points: (x,4) and (6,-1)The slope of two points is:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]\frac{-1 -4}{6 -x} = 56[/tex]
Evaluate the difference
[tex]\frac{-5}{6 -x} = 56[/tex]
Cross multiply
56(6 - x) = -5
Divide both sides by 56
6 - x = -0.09
Make x the subject
x = 6 + 0.09
Evaluate
x = 6.09
Hence, the value of x that yields a slope of 56 is 6.09

A trapezoid with short base fourteen centimeters, long base thirty-eight centimeters, height sixteen centimeters, and diagonal side lengths twenty centimeters.
320 square centimeters
608 square centimeters
416 square centimeters
560 square centimeters
Answer:
416 square centimeters
Step-by-step explanation:
Formula for finding area of a trapezoid :
A = 1/2 x (a + b) x h
a and b = parallel sides of the trapezoidh = height of the trapezoidSolving :
A = 1/2 x (38 + 14) x 16A = 8 x 52A = 416 square centimetersAnswer:
416 cm²
Step-by-step explanation:
The figure we are given, is a trapezoid. Let's apply the "area of trapezoid" formula to determine the area of the trapezoid provided.
[tex]\boxed{\text{Area of trapezoid:} \ \dfrac{a_1 + a_2}{2} h}[/tex]
[Where a₁ and a₂ are the measure of the parallel sides and h is the height]
Let's plug the height and the parallel sides into the formula and simplify it:
[tex]\text{Area of trapezoid} = \dfrac{38 + 14}{2} \times 16}[/tex]
[tex]\text{Area of trapezoid} = \dfrac{52}{2} \times 16}[/tex]
[tex]\text{Area of trapezoid} = 26 \times 16}[/tex]
[tex]\boxed{\text{Area of trapezoid} = 416 \ \text{cm}^{2}}[/tex]
Therefore, the area of the trapezoid is 416 cm².

Rule: Subtract 2 from the input value
Step-by-step explanation:
Examine the pattern of the input and the corresponding output for the two given ordered pairs:
Input -2 → Output -4
Output - Input = -4 - (-2) = -2
Input 1 → Output -1
Output - Input = -1 - 1 = -2
Therefore to get the output value (y-value), we subtract 2 from the input value (x-value).
[tex]\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} -3 & -5 \\\cline{1-2} -2 & -4 \\\cline{1-2} -1 & -3 \\\cline{1-2} 0 & -2\\\cline{1-2} 1 & -1 \\\cline{1-2}\end{array}[/tex]
As the rule for the function is the subtract 2 from the input value to get the output value, we can write this as:
Output = Input - 2

Select all that apply
The parent function will translate 4 units to the left and reflect over the x-axis option (C) and (E) are correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = log x
First transformation:
Replace x → (x+4)
The parent function will shift left side by 4 units.
Second transformation:
Multiply the function with -1
The function will reflect over x-axis
The function becomes:
g(x) = -log(x+4)
Thus, the parent function will translate 4 units to the left and reflect over the x-axis option (C) and (E) are correct.

The kinetic energy (K) that an object has varies jointly with its mass (m) and the square of its velocity (v). The equation that represents this relationship is given by [tex]K=kmv^2[/tex] where k is the kinetic energy constant. If a bowling ball of mass 5 kilograms is traveling at 2 meters per second, its kinetic energy is 10 Joules. What is the kinetic energy of a bowling ball of mass 3 kilograms traveling at 2.6 meters per second?
The kinetic energy of the bowling ball with the mass and traveling at the given velocity is 10.14 Joules.
What is Kinetic Energy?Kinetic energy is simply a form of energy a particle or object possesses due to its motion.
It is expressed as;
K = (1/2)mv²
Where m is mass of the object and v is its velocity.
Given that;
Mass of the bowling ball m = 3kgVelocity of the bowling ball v = 2.6m/sKinetic energy K = ?We substitute the given values into the above equation.
K = (1/2)mv²
K = 0.5 × 3kg × (2.6m/s)²
K = 0.5 × 3kg × 6.76m²/s²
K = 10.14kgm²/s²
K = 10.14J
Therefore, the kinetic energy of the bowling ball with the mass and traveling at the given velocity is 10.14 Joules.
