Step-by-step explanation:
5. A pole has to be erected at a point on the boundary of a circular park of diameter 13 metres in
such a way that the differences of its distances from two diametrically opposite fixed gates A
and B on the boundary is 7m. Is it possible to do so? If yes, at what distances from the two gates
should the pole be erected?
Answer:
Thus, it is possible to erect a pole at a point p on the boundary of the park at distances 5m and 12m respectively from gates B and A.
Step-by-step explanation:
Let P be the required location of pole .
A and B are the two gates.
Let the distance of pole at p from gate be 'x' meters
i.e. PB = x m
•°• AP = (x + 7)m and AB = 13 m
•°• AP² + BP² = AB² => (x +7)² + x =13²
Rejecting x =-12, we get x = 5
•°• PB = 5m
and
AP = 12m

Vincent has $5 bills and $20 bills. He has a total of 24 bills and the total amount is $210. How many $5 bills does he have?
Help pls
Answer:
18
Step-by-step explanation
Let's say that the amount of 5 dollar bills is x and 20 dollar bills is y, with this we can make an equation
x + y = 24
With that we can say that
5x + 20y = 210
Because that is how much each bill costs and the amount of which will equal a total of 210
Solve this systems of equations using elimination
5x + 5y = 120
-5x - 20y = -210
-15y = -90
y = 6
Plug in y = 6 to the first equation.
x + 6 = 24
x = 18
18 is the amount of 5 dollar bills.

Which of the following represents an image of △LMN under a dilation with a scale factor of 14/?
HELP ME NOW!! RED IS THE ONE I GOT WRONG!
Answer:
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Dilation is the increase or decrease in size of a figure by a factor k. If k > 1, then the dilation is an increase whereas if k<1, then the dilation is a decrease.
From the diagram, since triangle LMN is dilated by a factor of 1/4, hence the size of LMN is reduce. Therefore:
L'M' = (1/4)LM, L'N' = (1/4)LN, N'M' = (1/4)NM
Also, the distance from point P to N' is one-fourth of the distance from point P to N.
The correct option is highlighted in the image attached.
a. Name two different ways to name the plane shown in the figure.
b. Name any three collinear points in the plane.
c. Name any two intersecting lines in the given plane.
Answer:
A. Plane SXT, Plane PQR
B. Points S, R, and T
C. Line ST and Line PQ intersect [] Line PQ and Line YX intersect
Step-by-step explanation:
For the image below we decrypt ;
Plane: PQR , SXTCollinear points: S, R, TIntersecting lines: PQ, XY and STThis is further explained below.
What are Plane, Collinear points, and Intersecting lines?Generally, a Plane is simply defined as three noncollinear endpoints, two parallel lines,
If two or more points are located on the same straight line, they are said to be collinear.
In conclusion, Intersecting lines cuts across one or more lines to create an intercept

40% of students prefer to use pencils over pens for their assignments. What is the probability that you randomly select four students and all four prefer to use pencils over pens?
Answer:
0.0233
Step-by-step explanation:
We are told that 40% of students prefer to use pencils over pens for their assignments.
This means 40 out of 100 students prefer to use pencils over pens.
Thus, for the first draw, P(pencil over pens for first draw) = 40/100
Since person using pencil over pens is selected without replacement, then, we now have a sample space of 99;
Second draw; P(pencil over pens for 2nd draw) = 39/99
Similarly, for third draw; P(pencil over pens for 3rd draw) = 38/98
For fourth draw; P(pencil over pens for 4th draw) = 37/97
Thus;
probability that you randomly select four students and all four prefer to use pencils over pens is;
P(all four prefer pencils over pens) = (40/100) × (39/99) × (38/98) × (37/97) = 0.0233

Erin calculated the average speed of her most recent run to be 120/16 miles per hour how is this friction expressed as a decimal
Answer:
[tex]\dfrac{15}{2}[/tex]
Step-by-step explanation:
The average speed of the Erin is 120/16 mph
Here,
Numerator = 120
Denominator = 16
mph = miles per hour
We need to find an expression expressed as a decimal.
So,
[tex]\dfrac{120}{16}=\dfrac{2\times 3\times 2\times 2\times 5}{2\times 2\times 2\times 2}\\\\=\dfrac{15}{2}[/tex]
So, the final answer is [tex]\dfrac{15}{2}[/tex].

A ball is thrown up in the air, and it's height (in feet) as a function of time (in seconds) can be written as h(t) = -16t2 + 32t + 6. Describe in detail (using formulas and/or specific steps needed) TWO ways to find the maximum height reached by the ball.
Answer:
1) Using properties of the quadratic equation:
Here the height equation is:
h(t) = -16t^2 + 32t + 6
We can see that the leading coefficient is negative, this means that the arms of the graph will open downwards.
Then, the vertex of the quadratic equation will be the maximum.
Remember that for a general quadratic equation:
a*x^2 + b*x + c = y
the x-value of the vertex is:
x = -b/2a
Then in our case, the vertex is at:
t = -32/(2*-16) = 1
The maximum height will be the height equation evaluated in this time:
h(1) = -16*1^2 + 32*1 + 6 = 22
The maximum height is 22ft
2) Second method, using physics.
We know that an object reaches its maximum height when the velocity is equal to zero (the velocity equal to zero means that, at this point, the object stops going upwards).
If the height equation is:
h(t) = -16*t^2 + 32*t + 6
the velocity equation is the first derivation of h(t)
Remember that for a function f(x) = a*x^n
we have that:
df(x)/dx = n*a*x^(n-1)
Then:
v(t) = dh(t)/dt = 2*(-16)*t + 32 + 0
v(t) = -32*t + 32
Now we need to find the value of t such that the velocity is equal to zero:
v(t) = 0 = -32*t + 32
32*t = 32
t = 32/32 = 1
So the maximum height is at t = 1
(same as before)
Now we just need to evaluate the height equation in t = 1:
h(1) = -16*1^2 + 32*1 + 6 = 22
The maximum height is 22ft
Can you help me with this?
The answer is A.
Step-by-step explanation:
Domain = all possible values of x
From the graph, we can tell that x can be any value as the graph goes on forever.
Hence Df = {x: x <== All real numbers}

Okey hey, hi, hello, all I want to know is how to put this dang thing on the number line but I have searched everywhere and no one can help me !!!!!!!!
Can you ?
Your graph would be correct if the given equation was |x| = 5
This is because |x| describes the distance x is from zero, and asking |x| = 5 means we want to find which values are 5 units away from zero: those two values being 5 and -5.
--------------
However, your teacher gave you instead |x| = -5. The distance cannot be negative, so |x| is never negative. Therefore, |x| = -5 has no solutions
The graph will simply be an empty number line with no points plotted on it.
