The equation 1.6: n = 0.16 can be written as: [tex]1.6 = 2.511^n[/tex]
And we know that this is correct because we can check that it is the equivalent by multiplying [tex]2.511^n[/tex] by itself n times which results in 1.6.
What is an exponent?
An exponent is a mathematical operation that represents the number of times a value is multiplied by itself. It is usually written as a small number raised to the power of a larger number, such as 2^3, which means 2 multiplied by itself 3 times, or 2 * 2 * 2 = 8.
To write the equation 1.6: n=0.16 using an exponent, we can divide both sides of the equation by 1.6 to get: n = 0.16/1.6 = 0.1
And then we can raise the base 10 to the power of n: [tex]10^n = 10^{0.1} = 2.511[/tex]
Hence, the equation 1.6: n = 0.16 can be written as: [tex]1.6 = 2.511^n[/tex]
And we know that this is correct because we can check that it is the equivalent by multiplying [tex]2.511^n[/tex] by itself n times which results in 1.6.

The percentage of people who are satisfied with the car are 60%.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that in a survey of 2000 people who owned a certain type of car, 1200 said they would buy that type of car again.
The percentage of people who are satisfied with the car are -
{x}% = (1200/2000) x 100
{x}% = (12/20) x 100
{x}% = 12 x 5
{x}% = 60
Therefore, the percentage of people who are satisfied with the car are 60%.

Given that AB is a line segment and the angle
y
= 67°, work out the value of the angle marked
x
Answer:
x = 113°
Step-by-step explanation:
AB is a line segment and hence it is a straight line which means it is a straight angle, so it is 180° .
y = 67°
x = ?
So, x + y = AB
=> x + 67° = 180°
=> x = 180° - 67°
=> x = 113°
Therefore, x = 113°

A pendulum of length 1m and period 2.01s is placed at the top of Mount Everest
having an altitude of 8849m. Calculate the value of ‘g’ at that point.
Answer: A pendulum of length 1m and period 2.01s is placed at the top of Mount Everest having an altitude of 8849m. Calculate the value of 'g' at that point.
The period of this pendulum can be solved using the formula shown in the picture below. T is the period in seconds; L is the length in meters and g is the acceleration due to gravity which is equal to 9.81 m/s²near the equator.
T = 2 × π × (square root of 1.00 m / 9.81 m/s²)
T = 2 * 3.1416 * (square root of 0.101936799)
T = 6.2832 * 0.319275428
T = 2.00 seconds
The period of this pendulum correct to 3 significant figures is 2.00 seconds.
The frequency of this pendulum is solved by the formula f = 1/T
f = 1/2.00 seconds
f = 0.500 hertz

Find the lope-intercept equation of the line that pae through (1,-3) and ha a lope of -1/4
The slope intercept form of the equation is
y = -1/4x -11/4
What is Slope Intercept form ?One of the most popular ways to describe a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula may be used to get the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.
The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. Any point's coordinates on a straight line must fulfill a certain relation, which is known as the equation of a straight line.
Any location that is not on the line will not fulfill the coordinates.
This equation's solution is simple to find. A straight line's slope, or angle of inclination from the x-axis, and the intercept it makes with the y-axis are both necessary to determine the slope intercept form of the line.
The line passes through (1,-3)
slope = -1/4
The equation of the line
y = mx + c
here m is the slope and c is the intercept.
putting the point and slope in the equation
-3 = -1/4 *1 + c
⇒ c = -11/4
So the slope intercept form of the equation is
y = -1/4x -11/4

Find the midpoint of the given segment
[tex]midpoint = (\frac{(x_1+x+2)}{2}, \frac{(y_1+y_2)}{2})[/tex]
[tex](x_1,y_1)[/tex] = (3,7)
[tex](x_2,y_2)[/tex] = (7,-3)
∴ midpoint [tex](\frac{3+7}{2}, \frac{7+(-3)}{2})\\= (\frac{10}{2}, \frac{4}{2})\\= (5,2)[/tex]
2. Find the slope of the given segment
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex](x_1,y_1)[/tex] = (3,7)
[tex](x_2,y_2)[/tex] = (7,-3)
∴ slope [tex]m = \frac{-3-7}{7-3}\\= \frac{-10}{4}\\= \frac{-5}{2}[/tex]
3. Write the equation of the bisector equation in point-slope form
[tex]y - y_1 = m(x-x_1)[/tex]
4. Substitute the opposite-reciprocal of the given segment's slope into the bisector equation
The slope of the given segment is -5/2.
Therefore, the opposite-reciprocal of the given segment's slope is 2/5.
[tex]y - y_1 = \frac{2}{5}(x-x_1)[/tex]
5. Substitute the midpoint of the given segment into the bisector equation
midpoint = (5, 2)
[tex]y -2 = \frac{2}{5}(x-5)[/tex]
6. Expand & simplify the bisector equation to convert it into slope-intercept form
We need to convert [tex]y -2 = \frac{2}{5}(x-5)[/tex] into [tex]y = mx + b[/tex] form.

a. 16 cm
b. 32 cm
C. 64 cm
