Answer:
30%
Step-by-step explanation:
The level of decay is determined by the number raised to the power.
y = 0.4(0.7)^t
If you had 1^t, there would be no decay or growth since 1^t is always 1.
Instead, you have 0.7^t
As t increases, 07^t decreases. That is where the decay comes from.
Now look at 0.7
In the general decay equation, you have
y = a(1 - r)^t
r is the rate of decay.
Here we have 0.7
0.7 = 1 - 0.3
the rate of decay is 0.3 or 30%
Answer:
The equation y = 0.4(0.7)^t represents an exponential decay of 30%. The decay rate is determined by the value in the parentheses, which in this case is 0.7. To calculate the decay rate, you can subtract this value from 1, giving you 1 - 0.7 = 0.3, or 30%.

Bus 1 leaves Bulawayo at a constant speed of 80mph headed for Harare, 550 miles away. Bus 2 leaves Harare at 8:30AM traveling at 50mph. At what time will the buses pass each other?
The buses will pass each other at 12:37:30 PM
Calculation of time two buses pass each other.Bus 1 leaves Bulawayo at a constant speed of 80 mph headed for Harare, 550 miles away, Bus 2 leaves Harare at 8:30 AM traveling at 50 mph.To find the time when the two buses will meet, you need to find the time that Bus 2 will take to travel to the point where the buses will meet, and the time that Bus 1 will take to travel the same distance.
You can find the time that Bus 2 will take to travel to the point where the buses will meet by dividing the distance (550 miles) by the speed of Bus 2 (50 mph), which is 11 hours.
Then you can find the time that Bus 1 will take to travel the same distance by dividing the distance (550 miles) by the speed of Bus 1 (80 mph), which is 6.875 hours (or 6 hours and 52.5 minutes).
Now, you can subtract the time that Bus 2 takes to reach the point of intersection from the time that Bus 1 takes to reach the same point.
6.875 hours (or 6 hours and 52.5 minutes) - 11 hours = -4.125 hours (or -4 hours and 7.5 minutes)
Since Bus 2 leaves Harare at 8:30AM, you can subtract -4.125 hours from 8:30AM to find the time the buses will meet.
8:30AM - -4.125 hours = 12:37:30 PM
So the buses will pass each other at 12:37:30 PM

Note that the above problems are solved using the knowledge of the sum of angles in a triangle.
10) when computed, x = 13°
11) when computed m∠S = 158°
12) when computed, ∠P = 115.625°; ∠Q = 21.125°; ∠R = 43.25°
13) when computed, angles L, J, K is 52°, 45°, 83° respectively.
14) When computed,
∠b = 108°
∠c = 36°
∠d = 36°
What is the sum of angles in a Triangle?Note that the Triangles Theorem posits that the sum of Angles in a Triangle = 180°
10) To solve for x, we know that:
the triangle is an Equilateralall the angles are equalAll the angles sum up to 180°one of the angles is given as 8x-44°Given the above, we can state:
8x-44 = 180/3
8x-44 = 60
8x = 60 +44
x = 104/8
x = 13°
Thus x = 13°
11) For this problem, the key to solving for x is to note that the triangle is isosceles.
This means that,
15x - 31 = 9x + 11
Thus, collecting like terms, we have:
15x-9x = 11+ 31
24x = 42
x = 42/24
Thus,
x = 1.75
Since we are looking for m∠S, we can arrive at this by removing (15x - 31 ) + (9x + 11) from 180° based on the rule of the Sum of Angles in a triangle.
That is:
180 - (15x - 31 ) + (9x + 11) = m∠S
To do this, we must impute the value of x in to the above equation:
⇒ m∠S = 180 - ((15 * 1.75) - 31 ) + ((9 * 1.75) + 11)
⇒ m∠S = 180 - (-4.75) + 26.75
m∠S = 180 - 22; thus
m∠S = 158°
12) <M, <P, <R, recall that the sum of the interior angles of triangle MPR will add up to 180 degrees
so <M + <P + <R = 180
We have ∠P is 14 less than five times x = 5x-15
∠Q is five less than x = x - 5
∠R is nine less than twice x =2x - 9
Recall the angle sum property of the triangle: The sum of all angles of a triangle is 180°
So, 5x -15 + x - 5 + 2x - 9 = 180°
Collect like terms to get
8x - 29 = 180
8x = 180+29
Thus,
x= 26.125
So,∠P = 5x-15
=5 (26.125) -15
∠P = 115.625°
∠Q =x-5
=26.125 - 5
∠ Q =21.125°
∠R = 2x - 9
=2(26.125)-9
Thus
∠R = 43.25°
To confirm, if the above ∠ sum up to 180°, we say
Check 43.25+21.125+115.625
⇒ 43.25+21.125+115.625 = 180° is TRUE.
13) To solve for ∠J, ∠K and ∠ L, recall that
The sum of the interior angles of triangle JKL will add up to 180 degrees
so <J + <K + <L = 180
L = measure of angle L
J = measure of angle J = L - 7
K = measure of angle K = 2L - 21
Thus, L + L-7 + 2L - 21 = 180; Collect like terms and we have
4L - 28 = 180
4L = 208
L = 52°,
If L is 52 then
J = L - 7 = 52 - 7
= 45°
K = 2L - 21 = 2(52) - 21
= 83
To check that they all sum up to 180° we say:
52+ 45+83
= 180°
14)
The sum of angle in a triangle is 180 degrees
Hence <b + <c + <d = 180
13x-35 + 5x - 19 + 2x + 14 = 180
13x+5x+2x-35-19+14 = 180
20x-40 = 180
20x = 180 + 40
20 x = 220
x = 220/20
x = 11
Get <b
<b = 13x-35
<b = 13(11) - 35
<b = 143-35
<b = 108 degrees
Get <c

Lisa makes $30 for 4 hours of babysitting. Write an equation to represent her earnings, e, relative to the number of hours, h, that she works. Assume the relationship is proportional.
Answer: e = 7.5*h
Step-by-step explanation: The relationship between Lisa's earnings, e, and the number of hours, h, that she works is proportional. This means that the ratio of e to h is constant. One way to represent this relationship is through an equation of the form:
e = k*h
where k is a constant of proportionality. In this case, we know that Lisa earns $30 for 4 hours of babysitting, so we can use this information to find the value of k:
30 = k*4
k = 30/4 = 7.5
So the equation that represents Lisa's earnings, e, relative to the number of hours, h, that she works is:
e = 7.5*h
Where e is the earnings and h is the number of hours and 7.5 is the constant of proportionality.
Alternatively, you can write the equation as e = 30/4 * h = 7.5 * h
This equation tells us that for every hour that Lisa babysits, she earns $7.5.

7.5

What is the formula of remainder theorem?
The constant f(a) is the result of dividing a polynomial f(x) by xa, and f(x)=q(x)(xa)+f(a), where q(x) is a polynomial of degree one lower than f(x )'s.
What are polynomials?Algebraic expressions called polynomials include constants and indeterminates.
Polynomials can be thought of as a type of mathematics.
Nearly all branches of mathematics employ them to express numbers, and calculus is one of those branches where they play a crucial role.
A specific kind of expression is a polynomial.
A mathematical statement without the equals symbol (=) is called an expression. Let's examine the definition and usage of polynomials as they are described below.
An algebraic expression known as a polynomial requires that all of its exponents be whole numbers.
Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Hence, The constant f(a) is the result of dividing a polynomial f(x) by xa, and f(x)=q(x)(xa)+f(a), where q(x) is a polynomial of degree one lower than f(x )'s.

The remainder theorem helps us find the remainder when dividing a polynomial by a linear expression, using the formula R = f(a), where a is the root of the linear expression. Using this formula, we can easily calculate the remainder without performing long division.
The remainder theorem is a concept in algebra that helps us find the remainder when we divide a polynomial by a linear expression. The formula for the remainder theorem can be stated as follows:
If we have a polynomial f(x) and we divide it by a linear expression x - a, then the remainder R is given by the formula:
R = f(a)

What is the y-intercept of y 5x 10?
The y-intercept of y = 5x − 10 is -10.
If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.
The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, c, represents the y-coordinate of the point where the graph of the line intersects the y-axis.
Now, if we equate the standard slope-intercept form of the equation with the given equation, we get
y = mx + c
y = 5x - 10
m = 5 and c = -10
As we know the c is the y-intercept which is equal to -10.

What is grading system?Grading in education is the practice of assigning standardized grades to students based on their degree of success in a course. Grades can be assigned in the form of letters, a range, a percentage, or a number out of a potential total. Grades are averaged in certain countries to get a grade point average. A 10-point grading scale is commonly used in Indian institutes (though some use a 4-point scale). Your GPA is derived by dividing the entire amount of your grades by the number of credits you took.
