Final answer:
Katie was a quarter of an hour, or 15 minutes, late to school which starts at 8:55 AM. So, she arrived at 9:10 AM.
Explanation:
If school starts at 8:55 AM and Katie was a quarter of an hour late, that means she was 15 minutes late because a quarter of an hour is 15 minutes (60 minutes divided by 4 equals 15 minutes).
To find out what time Katie arrived, we need to add 15 minutes to the starting time of school:
School starts: 8:55 AM
Time late: + 15 minutes
Time of arrival: 9:10 AM
So, Katie arrived at school at 9:10 AM.
If [tex]sin\theta = \frac{1}{3}[/tex] , [tex]\frac{\pi }{2} \ \textless \ \theta \ \textless \ \pi[/tex]. Find the exact value of
[tex]sin (\theta + \frac{\pi }{6})[/tex]
Answer:
- 0.183
Step-by-step explanation:
Given that [tex]\sin \theta = \frac{1}{3}[/tex]
and [tex]\frac{\pi }{2} < \theta < \pi[/tex]
We have to find the exact value of [tex]\sin (\theta + \frac{\pi }{6} )[/tex].
Now, [tex]\sin \theta = \frac{1}{3}[/tex]
⇒ [tex]\theta = \sin ^{-1} (\frac{1}{3} ) = 19.47[/tex]
Now, since [tex]\frac{\pi }{2} < \theta < \pi[/tex],
So, [tex]\theta = 180 - 19.47 = 160.53[/tex]
{Since [tex]\sin \theta = \sin (180 - \theta)[/tex]
Now, [tex]\theta + \frac{\pi }{6} = 160.53 + 30 = 190.52[/tex]
Hence, [tex]\sin (\theta + \frac{\pi }{6} )[/tex].
= [tex]\sin 190.52[/tex]

the price of an air conditioner was reduced from rs 27000 to rs 24000 find the rate of percentage
Answer:
The percentage decrease in price of Air conditioner is 33.33%
Step-by-step explanation:
Given as :
The initial price of air conditioner = Rs 27000
The reduce price of air conditioner = Rs 24000
Let the rate of percentage = x %
So, % decrease = [tex]\frac{\textrm initial value - \textrm final value}{\textrm initial value}[/tex] × 100
Or, % decrease = [tex]\frac{\textrm 27000 - \textrm 24000}{\textrm 27000}[/tex] × 100
Or , % decrease = [tex]\frac{3000}{27000}[/tex] × 100
Or, % decrease = [tex]\frac{100}{9}[/tex]
Or. % decrease = 33.33 %
Hence The percentage decrease in price of Air conditioner is 33.33% Answer
The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Graph titled Distance Vs Time is shown with Time in minutes along the x-axis and Distance from Nest in miles along the y-axis. The scale on the x-axis shows the numbers 0 to 25 at increments of 5, and the scale on the y-axis shows the numbers 1 to 8 at increments of 1. A straight line joins the ordered pairs 0, 3 and 5, 4 and 10, 5 and 15, 6 and 20, 7.
Based on the graph, what is the initial value of the graph and what does it represent?
3 miles per minute; it represents the speed of the bird
0.2 mile per minute; it represents the speed of the bird
0.2 mile; it represents the original distance of the bird from its nest
3 miles; it represents the original distance of the bird from its nest
Answer:
[tex]0.2[/tex] miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.
Step-by-step explanation:
As there is no graph mentioned here but the information are quite sufficient to answer the question.
We have points [tex](0,3), (5,4),(10,5)...[/tex]
From these points we can find the slope of the line .
From point slope formula [tex]y-y_1=m(x-x_1)[/tex]
And assigning [tex](x,y) (0,3)[/tex] and [tex](x_1,y_1) (5,4)[/tex]
[tex]m=\frac{y_1-y}{x_1-x} =\frac{4-3}{5-0} =\frac{1}{5}=0.2[/tex]
This slope is also the speed of the bird which is [tex]0.2\ miles\ per\ minute.[/tex]
As by plugging the values of any coordinate point we can confirm this.
Lets put [tex](10,5)[/tex], y-axis is the distance so in [tex]10[/tex] minutes the the distance covered by the bird must be equal to to y-axis value which is [tex]5[/tex] miles.
[tex]y=0.2(x),y=0.2(10)=5\ miles[/tex]
Now as in [tex]t=0[/tex] the bird has started from y-intercept value [tex]3[/tex] so we can say that,the original distance of the bird from its nest is [tex]3\ miles[/tex].
So the correct choices are:[tex]B[/tex] and [tex]D[/tex]
The birds speed is [tex]0.2\ miles[/tex] per minute and is [tex]3\ miles[/tex] away from its nest.
Answer:
(d).
Step-by-step explanation:
The y-intercept (0, 3) is initial value of graph ⇒ (d). 3 miles; it represents the original distance of the bird from its nest

Step-by-step explanation:
To find characteristics of a quadratic equation from just looking at the graph is very simple. Here are few points which you can keep in mind which solving these type of questions.
If value of a (coefficient of [tex]x^{2}[/tex]) is positive then parabola will open upward and if value of a is negative then parabola will open downward.c is the value of y-intercept of the graph.The number of times the graph will cut the x-axis is the number of real roots of the equation. If graph touches the x-axis then the number of real roots will remain two but now they are equal so the number of solution will be one (For answering questions you can assume that the roots and solutions are one and the same thing so the answer of first question will be graph B). If it doesn't touch or cut the x-axis ( as in case of graph A ) the number of real roots is equal to zero but still there are two roots of this quadratic equation and now they are imaginary roots. (Number of roots of a quadratic are always two. Either both can be real or both can be imaginary)To check which type of roots a quadratic equation has you can check the discriminant of the equation which is (in terms of a, b, c)[tex]D=b^{2} -4ac[/tex]
if D > 0 then two distinct real roots (graph cuts x-axis at two distinct points)
if D = 0 then two equal real roots (graph touches x-axis)
if D < 0 then two imaginary roots (graph doesn't touch x-axis)
For graph A : D < 0 (as it has imaginary roots)
For graph B : D = 0 (as it touches the x-axis)
For graph C : D > 0 (as [tex]D=b^{2}-4ac=4^{2}-4 \times 1 \times (-2)=16+8=24[/tex])
Answer:
Graph B has one real root.
Graph A has a negative discriminant.
Graph C has an equation with coefficients

Step-by-step explanation:
Classify the equation 6(x + 2) = 5(x + 7) as having one solution,
no solution, or infinitely many solutions.
The equation 6(x + 2) = 5(x + 7) simplifies to x = 23, indicating it has one unique solution. Substituting back into the original equation verifies the solution.
To classify the equation 6(x + 2) = 5(x + 7) as having one solution, no solution, or infinitely many solutions, we first simplify the equation:
Distribute the 6 and the 5 to the terms inside the parentheses: 6x + 12 = 5x + 35.Subtract 5x from both sides to get: x + 12 = 35.Subtract 12 from both sides to find the value of x: x = 23.This provides us with one solution for the equation, which means the equation has a single unique solution. When we substitute x = 23 back into the original equation, we get an identity, confirming that our solution is correct.
Equations with a single solution, no solution, or an infinite number of solutions are encountered often in algebra. For example, 1+x+x² = 0 may have real or complex solutions and can demonstrate the principle that an nth degree polynomial has n solutions, which can include repeated or complex roots. The equation 205+111x +4x² - 31x³ - 10x4 +5x5=0 is a higher-degree polynomial that may require numerous iterations to find a solution, emphasizing the complexity of finding solutions for polynomial equations.
Solve dy/dx = sqrt x+16 subject to the initial condition y(0)=0
The solution to the differential equation [tex]\( \frac{dy}{dx} = \sqrt{x + 16} \)[/tex]with the initial condition y(0) = 0 is [tex]\( y = \frac{2}{3}(x + 16)^{3/2} - \frac{128}{3} \)[/tex].
To solve the differential equation [tex]\( \frac{dy}{dx} = \sqrt{x + 16} \)[/tex] with the initial condition y(0) = 0, we'll integrate both sides with respect to x.
Given:
[tex]\[ \frac{dy}{dx} = \sqrt{x + 16} \][/tex]
Integrating both sides:
[tex]\[ \int \frac{dy}{dx} \, dx = \int \sqrt{x + 16} \, dx \]\[ \int dy = \int \sqrt{x + 16} \, dx \]\[ y = \frac{2}{3}(x + 16)^{3/2} + C \][/tex]
Now, we'll apply the initial condition y(0) = 0 to find the value of the constant C:
[tex]\[ 0 = \frac{2}{3}(0 + 16)^{3/2} + C \]\[ 0 = \frac{2}{3}(16)^{3/2} + C \]\[ 0 = \frac{2}{3}(64) + C \]\[ C = -\frac{128}{3} \][/tex]
So, the particular solution to the differential equation with the initial condition is:
[tex]\[ y = \frac{2}{3}(x + 16)^{3/2} - \frac{128}{3} \][/tex]

given that -4 is a zero of the function f(x)=x3+3x2-16x-48f(x)=x3+3x2-16x48, find the other zeros and write f(x)f(x) in factored form
Answer:
f(x) = (x + 4)(x - 4)(x + 3)
The other zeros of the function are at 4 and -3.
Step-by-step explanation:
Given function is f(x) = x³ + 3x² - 16x - 48.
Now, given that - 4 is a zero of the given function.
So, the function has a factor equals to (x + 4).
Now, f(x) = x³ + 3x² - 16x - 48
⇒ f(x) = x³ + 4x² - x² - 4x - 12x - 48
⇒ f(x) = x²(x + 4) - x(x + 4) - 12(x + 4)
⇒ f(x) = (x + 4)(x² - x - 12)
⇒ f(x) = (x + 4)(x - 4)(x + 3)
Therefore, the other zeros of the function are at 4 and -3. (Answer)
Answer:
f(x) = (x + 4)(x - 4)(x + 3)

9. A stock's price has been continuously declining at a rate of 5% per week. If the stock started at a price of
$62.50 per share, algebraically determine the number of weeks it will take for the price to reach $20.00 per
share. Round your answer to the nearest tenth of a week
Final answer:
It will take approximately 13.6 weeks for the stock's price to reach $20.00 per share.
Explanation:
To determine the number of weeks it will take for the stock's price to reach $20.00 per share, we need to find the number of weeks it will take for the price to decrease from $62.50 to $20.00. Since the price is declining at a rate of 5% per week, we can set up an equation:
$62.50 - ($62.50 imes 0.05 imes ext{number of weeks}) = $20.00
Simplifying the equation, we have:
$62.50 - (0.05 imes 62.50 imes ext{number of weeks}) = $20.00
$42.50 = (0.05 imes 62.50 imes ext{number of weeks})
Dividing both sides by 0.05 and 62.50, we get:
ext{number of weeks} = rac{42.50}{0.05 imes 62.50}
Calculating this, we find that it will take approximately 13.6 weeks for the stock's price to reach $20.00 per share.
During her first year of college, Sara put $2000 in the bank to save for a trip to Italy after graduation. The money earned 3% simple annual interest. After 4 years, how much money did she have in the bank for her trip?
Answer:
Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Investment of Sara during her 1st year of college = US$ 2,000
Duration of the investment = 4 years
Annual interest rate = 3%
2. Let's find the future value of this investment after 4 years, using the following formula:
FV = PV * (1 + r) ⁿ
PV = Investment of Sara during her 1st year of college = US$ 2,000
number of periods (n) = 4
rate (r) = 3% = 0.03
Replacing with the real values, we have:
FV = 2,000 * (1 + 0.03) ⁴
FV = 2,000 * (1.03) ⁴
FV = 2,000 * 1.12550881
FV = 2,251.02
Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.

Answer:
Step V: Transitive property of Inequality
Step VI: Subtraction Property of Inequality
Step-by-step explanation:
In Step IV, the RHS of t=both the sides are equal.
So, they equated the LHS of both the sides.
This is the transitive property of equality which states that if a = b and c = b then a = c.
In this case, a = [tex]$ \angle {m_1} + \angle {m_2} $[/tex]
b = 180⁰
c = [tex]$ \angle {m_2} + \angle {m_3} $[/tex]
Consequently, [tex]$ \angle {m_1} + \angle {m_2} = \angle {m_2} + \angle {m_3} $[/tex]
In step VI, [tex]$ \angle {m_2} $[/tex] is subtracted on both the sides. So, this is called as Subtraction Property of Equality.

What values of a and b would make this equation work?
a=
b=
Answer:
[tex]a=15[/tex]
[tex]b=\frac{1}{3}[/tex]
Step-by-step explanation:
we have an exponential function of the form
[tex]y=a(b^x)[/tex]
where
a is the initial value or y-intercept
b is the base
Looking at the graph
we can see the ordered pairs (0,15) and (1,5)
(0,15) ---> y-intercept
so
The value of a is equal to
[tex]a=15[/tex]
substitute
[tex]y=15(b^x)[/tex]
with the point (1,5) find the value of b
For x=1, y=5
substitute in the exponential function
[tex]5=15(b^1)[/tex]
solve for b
[tex]5=15(b)[/tex]
[tex]b=\frac{1}{3}[/tex]
therefore
The exponential function is
[tex]y=15(\frac{1}{3}^x)[/tex]

Write the equation of the line that parallel to x = -3 and passes through the point (4, -7).
The equation of the line that parallel to x = -3 and passes through the point (4, -7) is y = -3x + 5
Solution:
The two forms of writing a point and slope in equation are point slope form and standard form.
The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers. The standard form of a line is just another way of writing the equation of a line.
The given point is (4,-7) and the slope is -3.
The slopes of parallel lines are always equal.
To write in standard form we will first write it in point slope form and then rearrange it into a standard from.
The equation of line in point slope form is given as:
[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]
[tex]\begin{array}{l}{y-(-7)=-3(x-4)} \\\\ {y+7=-3(x-4)} \\\\ {y+7=-3 x+12}\end{array}[/tex]
y = -3x + 5
Now, let us convert this equation to standard form
3x + y = 5
Thus the equation of line in point slope and standard form is found out
The function h(t) = - 16t ^ 2 + 32t + 24 represents the height of an object t seconds after being launched straight into the air. What does -16 represent?
A)initial velocity
B)time until the object hits c) the ground maximum height
D) acceleration due to gravity
Answer:
D
Step-by-step explanation:
When we differentiate the function, we get -32x + 32, which is the velocity function of the original.
When we differentiate again, we get -32, which is derived from the initial -16. This -32 represents the acceleration, because it is the 2nd derivative.
Hence, the answer is D, acceleration due to gravity.
Two buses depart two cities moving in the same direction. The speed of the first bus is 54 mph which is 60% of the speed of the second bus. The faster bus caught up to the other bus one hour and thirty minutes after the departure. will give brainliest
Answer:
The second city is 54 miles behind the first city
Step-by-step explanation:
The first bus is assumed to go ahead of the second bus and is moving at 54 mph. The second bus is moving at a speed such as 54 mph is 60% (0.6) of its speed.
The speed of the second bus is then 54/0.6 = 90 mph
When 1 and a half hour has passed, the first bus has moved a distance of
[tex]X_1=54\times 1.5[/tex] = 81 miles
The second bus (behind the first bus) has moved
[tex]X_2=90\times 1.5[/tex] = 135 miles
The problem states they both meet in that time, it can only be possible if the second bus departed a distance 135 - 81 = 54 miles behind the first city
So, the second city is 54 miles behind the first city
Which lines is a parallel to the line y=1/2x+5 and passes through the point (-2,1)?
Answer:
The answer is: y = 1/2x + 2
Step-by-step explanation:
Given equation: y = 1/2x + 5
Given point: (-2, 1)
The slope of the given line is 1/2. Parallel lines have the same slope.
Use the point slope form and solve for y:
y - y1 = m(x - x1)
y - 1 = 1/2(x - (-2))
y - 1 = 1/2(x + 2)
y - 1 = 1/2x + 1/2 * 2
y - 1 = 1/2x + 1
y = 1/2x + 2
Proof:
f(-2) = 1/2(-2) + 2
= -1 + 2
= 1, giving point (-2, 1)
Hope this helps!! Have an Awesome Day!! :-)
15 - 4x = 6 - 3x
whats the answer.
Answer:9
Step-by-step explanation: First you add the 3x to both sides(the -4x and the -3x) and then you get 15-1x=6. Next you subtract 15 from 15 and 6, so you get -1x=-9. So then you divide both sides by -1 (do -1x over -1 equals -9 over -1). Last you do the dividing and you get x=9.
Isolate the variable x by moving terms involving x to one side and constants to the other side. Simplify the equation step-by-step to find that x = 9.
To solve the equation 15 - 4x = 6 - 3x, we need to isolate the variable x. Follow these steps:
Start by getting all the terms involving x on one side of the equation. We can do this by adding 3x to both sides:Therefore, the solution to the equation 15 - 4x = 6 - 3x is x = 9.
- 2x + y = 14

Equation 1) -2x + y = 14
Equation 2) 4x - 6y = 4
Add 2x to both sides of equation 1 so that we can get the value of y.
y = 2x + 14
Now, plug the value of y into our second equation.
4x - 6(2x + 14) = 4
Simplify.
4x - 12x - 84 = 4
Add 84 to both sides.
4x - 12x = 4 + 84
Simplify.
-8x = 88
Divide both sides by -8.
x = -11
Now, plug our value of x into our first equation in order to find y.
-2x + y = 14
-2(-11) + y = 14
22 + y = 14
y = -8
Therefore, the systems of equation variables are : (-11, -8)
~Hope this helped! :)
