Determine whether the geometric series 25 − 5 + 1 − 0.2 ... converges or diverges, and identify the sum if it exists.
Answers
Answer:
Converges
Sum = 20.8333
Step-by-step explanation:
A geometric series has a general formula of:
[tex]\sum ar^n[/tex]
Where 'a' is the initial term, 'n' is the number of terms, and 'r' is the constant ratio. If |r| < 1 than the series converges.
In this particular case, the initial term is a=25, and each term is being divided by -5, or multiplied by -0.2, so the general form would be:
[tex]\sum 25*(-0.2)^n[/tex]
Since 0.2 < 1.0, the series converges.
The sum of the series is given by:
[tex]S=\frac{a}{1-r}\\S=\frac{25}{1-(-0.2)}\\S=20.8333[/tex]
The sum is 20.8333.
The geometric series converges and the sum is equal to 20.83.
What is a Geometric Series ?A geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms .
A geometric series has a general formula of:

In this particular case, the initial term is a=25 and each term is divided by -5 or multiplied by (-0.2)
Therefore r = -0.2 and as it is <1 therefore the series converges
The sum of a convergent series is
S = a/(1-r)
S = 25/(1-(-0.2))
S= 25/1.2
S = 20.83

3. The probability of a marksman scoring a bulls-eye on any shot is 0.26. The probability
of an inner is 0.42 and the probability of an outer is 0.24. What is the probability of each of
the following:
a) Scoring an inner or better. This means an inner or closer.
b) Failing to hit the target.
c) Failing to score a bulls-eye.
Answers
Answer:
a) 0.68
b) 0.08
c) 0.74
Step-by-step explanation:
Given that:
Probability of hitting bulls eye, P(B) = 0.26
Probability of an inner, P(I) = 0.42
Probability of an outer, P(O) = 0.24
a) Probability of hitting an inner or better (inner or bulls eye):
P(I or B) = P(I [tex]\cup[/tex] B)
Formula for P(P [tex]\cup[/tex] Q) where P(P) and P(Q) are the probabilities of two mutually exclusive events i.e. having nothing in common:
P(P [tex]\cup[/tex] Q) = P(P) + P(Q)
P(I [tex]\cup[/tex] B) = P(I) + P(B) = 0.26 + 0.42 = 0.68
b) Probability of failing to hit the target:
P(F) = 1 - (P(B)+P(I)+P(O))
P(F) = 1 - (0.26 + 0.42 + 0.24)) = 1 - 0.92 = 0.08
c) Probability of failing to score a bulls eye:
P(B)' = 1 - P(B) = 1 - 0.26 = 0.74
So, the answers are:
a) 0.68
b) 0.08
c) 0.74
The congruence theorem that can be used to prove △LON ≅ △LMN is SSS. ASA. SAS. HL.
Answers
Answer:
The correct option is SSS (Side-Side-Side) Theorem
Step-by-step explanation:
The question is incomplete because the diagrams of ΔLON and ΔLMN are not given. I have attached the diagram of both triangles below for better understanding of the question.
Consider the diagram attached below. We have to find the congruence theorem which can be used to prove that ΔLON ≅ ΔLMN
We can see in the diagram that both triangle have a common side that is LN. It means 1 side of both triangles is congruent because LN≅LN
Consider the sides ON and MN. Both side have a single bar on them, which means that it is given that both of these side are congruent. Hence ON≅MN
Consider the sides LO and LM. Both side have a double bars on them, which means that it is given that both of these side are also congruent. Hence LO≅LM
SSS theorem states that if all sides of the triangles are congruent, then the triangles themselves are also congruent, which is the same case in this question

The given equation is y = x, which is parallel to y = x + 3
Also, the equation I chose has an x-intercept of -3.
The equation of the line that is parallel to the given line and has an x - intercept of - 3 is,

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (3, 1) and (0, -1).
Now,
Since, The equation of line passes through the points (3, 1) and (0, -1).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 1 - 1) / (0 - 3)
m = - 2 / - 3
m = 2/3
Thus, The equation of line with slope 2/3 is,
⇒ y - 1 = 2/3 (x - 3)
⇒ y - 1 = 2/3x - 2
⇒ y = 2/3x - 1
Therefore, The equation of the line that is parallel to the given line and has an x - intercept of - 3 is,
⇒ y = 2/3x - 1

A particle is moving along a projectile path at an initial height of 96 feet with an initial speed of 16 feet per second. This can be represented by the function H(t) = −16t2 + 16t + 96. What is the maximum height of the particle?
Answers
Answer:
The maximum height the projectile reaches is 100 feet
Step-by-step explanation:
Notice that the given equation representing the height of the projectile is a quadratic equation which negative leading coefficient (-16). Such type of equations would have a parabola that branches downwards as its graph.
therefore, what we need to find is the coordinates of the top vertex of that parabola. We can use for such the typical formula for the x-position of the vertex of a parabola with standard equation:
[tex]f(x)=ax^2+bx+c[/tex]
with x-position of the vertex given by:
[tex]x_v=\frac{-b}{2a}[/tex]
Then in our case ([tex]H(t)=-16t^2+16t+96[/tex]) we have:
Horizontal position of the vertex given by:
[tex]t_{vertex}=\frac{-16}{2(-16)} =\frac{1}{2}[/tex]
and now we can find the maximum height plugging this value into the height expression:
[tex]H(t)=-16(\frac{1}{2}) ^2+16\,(\frac{1}{2})+96=-4+8+96=100\,\,ft[/tex]

Answers
Answer:
The resultant velocity is 12.21 m/s.
Step-by-step explanation:
We are given that the water from a fire hose follows a path described by y equals 2.0 plus 0.9 x minus 0.10 x squared (units are in meters).
Also, v Subscript x is constant at 10.0 m/s.
The water from a fire hose follows a path described by the following equation below;
[tex]y=2.0 + 0.9x-0.10x^{2}[/tex]
The velocity of the [tex]x[/tex] component is constant at = [tex]v_x=10.0 \text{ m/s}[/tex]
and the point at which resultant velocity has to be calculated is (9.0,2.0).
Let the velocity of x and y component be represented as;
[tex]v_x=\frac{dx}{dt} \text{ and } v_y=\frac{dy}{dt}[/tex]
Now, differentiating the above equation with respect to t, we get;
[tex]y=2.0 + 0.9x-0.10x^{2}[/tex]
[tex]\frac{dy}{dt} =0 + 0.9\frac{dx}{dt} -(0.10\times 2)\frac{dx}{dt}[/tex]
[tex]\frac{dy}{dt} = 0.9\frac{dx}{dt} -0.2\frac{dx}{dt}[/tex]
[tex]v_y = 0.9v_x -0.2v_x[/tex]
[tex]v_y = 0.7v_x[/tex]
Now, putting [tex]v_x=10.0 \text{ m/s}[/tex] in the above equation;
[tex]v_y = 0.7 \times 10.0[/tex] = 7 m/s
Now, the resultant velocity is given by = [tex]v=\sqrt{v_x^{2}+v_y^{2} }[/tex]
[tex]v=\sqrt{10^{2}+7^{2} }[/tex]
= [tex]\sqrt{149}[/tex] = 12.21 m/s
