Answer:
m = 5
p = 10
Step-by-step explanation:
Part A
The dashes on the lines mean that the lines are equal in length.
Therefore, IJ = IH and HK = KJ
So as IJ = IH
⇒ 10 = 2m
⇒ m = 10 ÷ 2
⇒ m = 5
Part B
The line IK is the bisector of angle I since IJ = IH and HK = KJ
Therefore, 2p - 5 = p + 5
subtract p from both sides:
⇒ 2p - 5 - p = p + 5 - p
⇒ p - 5 = 5
Add 5 to both sides:
⇒ p - 5 + 5 = 5 + 5
⇒ p = 10

The acceleration of a Maserati (sports car) is proportional to the difference between 250 km/h and its velocity. If the car can accelerate from rest to 100 km/h in 10 s, how long will it take for the car to accelerate from rest to 200 km/h?
Answer:
a) The differential equation for the velocity is given by
(dv/dt) = k(250 - v)
b) v(t) = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾
With units of km/h
Step-by-step explanation:
Acceleration, a ∝ (250 - v)
But acceleration is widely given as dv/dt
(dv/dt) ∝ (250 - v)
(dv/dt) = k(250 - v)
where k = constant of proportionality
(dv/dt) = k(250 - v)
b) (dv/dt) = k(250 - v)
dv/(250 - v) = k dt
∫ dv/(250 - v) = ∫ k dt
- In (250 - v) = kt + c (where c is the constant of integration)
v(0) = 0; meaning, at t = 0, v = 0
- In 250 = 0 + C
c = - In 250 = - 5.52
- In (250 - v) = kt - 5.52
In (250 - v) = 5.52 - kt
250 - v = e⁽⁵•⁵² ⁻ ᵏᵗ⁾
v = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾
With units of km/h

Answer:
[tex]\displaystyle [7x + 2][3x - 7][/tex]
Step-by-step explanation:
Find two quantities that when differed to 43, they also multiply to 294. Those will be 6 and 49. The TINIER quantity gets the plus symbol because the B-value is −43, therefore 49 gets the minus symbol, leaving 6 with the plus symbol. In extension, sinse we have a leading coefficient greater than one, we need to take extra procedures. Here is how it is done:

If the graph of f(x)=x2, how will the graph be affected if the coefficient of x2 is changed to 3?
Answer:
435
Step-by-step explanation:
Transformations are used to change the orientation of a function to a new function. The graph of [tex]f(x) = x^2[/tex] will have its parabola widened when it changes to [tex]g(x) = 3x^2[/tex]
Given that
[tex]f(x) = x^2[/tex]
If the new function is:
[tex]g(x) = 3x^2[/tex]
It means that f(x) has been vertically translated by a scale factor of 3.
The graph will be affected such that the parabola of [tex]f(x) = x^2[/tex] will become widen when the coefficient changes to 3 i.e. [tex]g(x) = 3x^2[/tex].

Tanya performed an experiment in which she randomly pulled a marble from a bag, recorded its color, put it back, and then repeated. The following table represents the number of times each color of marble was pulled.
Color of Marble Frequency
Green 25
Blue 35
Purple 40
If Tanya repeats the experiment 50 more times, how many of those times should she expect to pull a purple marble?
Enter your answer as a number, like this: 42
Answer:20
Step-by-step explanation: Add all the marbles up = 100 divided by 2 = 50 so then divide the purple marble by 2 =20.
Tanya should expect to pull a purple marble for 8 times.
What is experimental probability?The experimental probability of an event is based on the number of times the event has occurred during the experiment and the total number of times the experiment was conducted.
Given that, Tanya performed an experiment in which she randomly pulled a marble from a bag,
Out of the experiment that Tanya performed, we can get an experimental probability.
This experimental probability is given by the quotient between the frequency for each color, and the total number of trials.
The total number of trials is:
N = 25 + 35 + 40 = 100
And on 40 of these, she got a purple marble, then the experimental probability of getting a purple marble is:
p = 40/100 = 0.4
Now, if she draws 50 marbles more, she should expect to get:
0.4×50 = 8
Hence, Tanya should expect to pull a purple marble for 8 times.

On a game show, contestants shoot a foam ball toward a target. The table includes points along one path the ball can take to hit the target where x is the time that has passed since the ball was launched and y is the height at this time. Time (x) Height (y) 0 10 2 24 16 10 How high was the ball after 8 seconds? 20 feet 42 feet 96 feet 106 feet.
After 8 seconds the ball height was 42 units.
It is given that on a game show, contestants shoot a foam ball toward a target. The table includes points along one path the ball can take to hit the target where x is the time that has passed since the ball was launched and y is the height at this time.
It is required to find how high was the ball after 8 seconds.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
The orbit of the ball will be a parabola.
We know the standard form of a quadratic function:
[tex]\rm y=ax^2+bx+c[/tex] where [tex]\rm \\a\neq 0[/tex]
At x = 0 and y = 10, we get:
[tex]\rm 10 =a(0)^2+b(0)+c\\\rm 10= c\\\rm c=10[/tex]
At x = 2 and y=24, we get:
[tex]\rm 24= a(2)^2+b(2)+c\\\rm 24=4a+2b+10\\\rm 4a+2b=14[/tex]....(1)
At x = 16 and y = 10, we get:
[tex]\rm 10= a(16)^2+b(16)+c\\\rm 10=256a+16b+10\\\rm 256a+16b=0 \\[/tex]....(2)
By solving equations (1) and (2), we get;
a = - 1/2, b = 8 and c = 10
Putting these values in the standard form of a quadratic function, we get:
[tex]\rm y = - \frac{1}{2} x^2+8x+10\\[/tex]
Now, after 8 seconds means when x = 8, we get:
[tex]\rm y=-\frac{1}{2}\times 8^2 +8\times8+10\\\rm y = -32+64+10\\\rm y= 42[/tex]
Thus, after 8 seconds the ball height was 42 units.

What is the y-intercept of 5x+4y=−40 ?
A.(8,−10)
B.(0,−10)
C.(0,8)
D.(−10,0)
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
5x + 4y = - 40 ( subtract 5x from both sides )
4y = - 5x - 40 ( divide all terms by 4 )
y = - [tex]\frac{5}{4}[/tex] x - 10 ← in slope- intercept form
with y- intercept c = - 10 ⇒ (0, - 10 ) → B
Step-by-step explanation:
To find the y intercept of the line we must first write the equation in standard form which is
y = mx + c
where
m is the slope
c is the y intercept
So we have
5x + 4y = - 40
4y = -5x - 40
Divide both sides by 4
We have the equation as
[tex]y = - \frac{5}{4} x - 10[/tex]
From the question the y intercept is - 10
We have the final answer as
( 0 , - 10)Hope this helps you

400+200=600200+200=4000+200=200So
the relationship is
y=200+xOption C
Answer:
C. [tex]y=x+200[/tex]
Step-by-step explanation:
Line of best fit (trendline) : a line through a scatter plot of data points that best expresses the relationship between those points.
All the given options for the line of best fit are linear equations.
Therefore, we can add the line of best fit to the graph (see attached), remembering to have roughly the same number of points above as below the line.
Linear equation: [tex]y=mx+b[/tex]
(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)
From inspection of the line of best fit, we can see that the y-intercept (where x = 0) is approximately 200. So this suggests that either option C or option D is the solution.
We can also see that slope (gradient) is approximately 1, as for every +100 increase in x, y increases by +100.
[tex]\textsf{slope = rate of change}=\sf\dfrac{change \ in \ y}{change \ in \ x}=\dfrac{100}{100}=1[/tex]
Therefore, this suggests that C is the solution and that the closest approximation to the line of best fit is [tex]y=x+200[/tex]

How can you show that 20% of $165.00 is $33.00?
Can someone help me please thanks
Answer:
True
Step-by-step explanation:
0.20*165=33
Answer:
With the definition of percentage. 20% of something means multiplying it by 20 and then dividing the result by 100. In our case, [tex]165.00 \times 20 \div 100 = 33.00[/tex]
Alternatively, convert it into a fraction. 20 is 1/5 of 100 (alternatively, you need to pick 20 five times to get 100), and then you just multiply
[tex]165.00 \times \frac15 = 33.00[/tex]
∠A and ∠B are complementary. The measure of ∠A is 21°.
What is the measure of ∠B?
Enter your answer in the box.
°
complementary angles is when the sum of two angles is equal to 90 degrees.
∠A + ∠B = 90°
21° + ∠B = 90°
∠B = 90° - 21°
∠B = 69°
Answer:
∠B = 69°
Step-by-step explanation:
Complementary angles are such pairs of angles that sum up to 90°. In this case, we are given that ∠A and ∠B are a pair of complementary angles. This means that ∠A and ∠B sum up to 90°.
⇒ [tex]\angle A + \angle B = 90\°[/tex]
⇒ [tex]21\° + \angle B = 90\°[/tex] [∠A = 21°]
⇒ [tex]\angle B = 90 - 21[/tex]

Step-by-step explanation:
Standard notation is when you move the decimal however many times the 10 is being squared by. In this case, it is 8.
Since the 8 is not negative, we move it 8 times to the right.
Since there are only 2 digits, we add 6 more zeros because 2+6=8
