Which Of The Following Could Be The Points That Jamur Plots? (2024)

From the question the following can be derived:

(a)

Let x cans of juice and y cans of soda be purchased for the dorm. Then the cost of the juice and soda is 0.60x + 0.75y. The equation of all the combinations of juice and soda is 0.60x + 0.75y = 24.

(b)

The cost of exactly 24 cans of juice is $24 * 0.60 = $14.40. After this purchase, the remaining sum of money available is $24 - $14.40 = $9.60. This will suffice to buy 12 cans of soda, leaving a balance of $0.80. Thus. the entire money cannot be spent if exactly 24 cans of juice are purchased.

(c)

Below is a graph of the line 0.6x + 0.75y = 24 or 4x + 5y = 160 is plotted. All possible cimbinations of juice and soda will lie on this line. The x-intercept is 40 and the y-intercept is 32. Since neither of x and y can be negative, hence the lower and upper bounds for x are 0 and 40 and the lower ad upper bounds for y are 0 and 32. Also , x has to be multiple of 5 and y has to be a multiple of 4. As may be observed from the graph, only 9 combinations are possible which are (x, y):

(0, 32), (5, 28), (10, 24), (15, 20), (20, 16), (25, 12), (30, 8), (35, 4), (40, 0).

Graph:

Part a)

Perimeter = 340 = 2•77 + Length doubled

then

Length x 2 = 340 - 154 = 186

Length= 186/2 = 93

ANSWER IS Length of parking lot is= 93 meters

Part b)

Area = 7410 = Width x Length

. 7410 = Width x 95

. 7410/95 = Width

THEN Width of the pool IS

78 square meters

The system of equation x + 3y = 6 and 2x + 6y = -18 has no solution.

What is the solution to the given system of equation?

Given the system of equation in the question;

x + 3y = 6

2x + 6y = -18

To find the solution to the system of equation, first solve for x in the first equation.

x + 3y = 6

Subtract 3y from both sides

x + 3y - 3y = 6 - 3y

x = 6 - 3y

Now, replace all occurrence of x in the second equation with 6 - 3y and solve for y

2x + 6y = -18

2( 6 - 3y ) + 6y = -18

Apply distributive property to remove the parenthesis

12 - 6y + 6y = -18

-6y and +6y cancels out

12 = -18

Since 12 equal -18 is not true, there is no solution to the system of equation.

To determine the vertex form of a parabola has equation:

[tex]f(x)=a(x-h)^2+k[/tex]

where V(h,k) is the vertex of the parabola and 'a' is the leading coefficient.

From the question, we have that, the vertex is (-1, 1)

and the leading coefficient is a = 2

We substitute the vertex and the leading coefficient into the vertex form to

get:

[tex]\begin{gathered} f(x)=2(x+1)^2\text{+}1 \\ f(x)=2(x+1)^2+1 \end{gathered}[/tex]

The graph of this function is shown in the attachment.

Hence the equation of parabola is

[tex]f(x)=2(x+1)^2+1[/tex]

Given: The function below

[tex]f(x)=\frac{3x+30}{25x^2-49}[/tex]

To determine: All x-intercepts of the given function

The x-intercept is a point where the graph crosses the x-axis

We would substitute the function equal to zero and find the value of x

[tex]\begin{gathered} f(x)=\frac{3x+30}{25x^2-49},f(x)=0 \\ \text{Therefore} \\ \frac{3x+30}{25x^2-49}=0 \\ \text{cross}-\text{ multiply} \\ 3x+30=0 \end{gathered}[/tex][tex]\begin{gathered} 3x=-30 \\ \frac{3x}{3}=\frac{-30}{3} \\ x=-10 \end{gathered}[/tex]

Therefore, the coordinate of the x-intercept is (-10, 0)

EXPLANATION

The ratio of the area of the triangle to the area of the circle is:

[tex]5:6[/tex]

Let the area of the triangle be T.

1/5 of the area of the triangle is shaded i.e. 1/5 T

The total area of the figure is the sum of the area of the triangle that is not shaded and the area of the circle.

The area of the triangle that is not shaded is:

[tex]\begin{gathered} T-\frac{1}{5}T \\ \frac{4}{5}T \end{gathered}[/tex]

Let the area of the circle be C. The ratio of the area of the triangle to that of the circle is 5/6. This implies that:

[tex]\begin{gathered} \frac{T}{C}=\frac{5}{6} \\ \Rightarrow C=\frac{6T}{5} \end{gathered}[/tex]

And so, the area of the figure is in terms of T is:

[tex]\begin{gathered} \frac{4}{5}T+\frac{6}{5}T \\ 2T \end{gathered}[/tex]

Therefore, the ratio of the shaded area to the area of the figure is:

[tex]\begin{gathered} \frac{1}{5}T:2T \\ \Rightarrow\frac{1}{5}:2 \\ \Rightarrow1:10 \end{gathered}[/tex]

If Jaylen used a 20% discount on a pair of jeans that cost $70 before tax, then the price of the jeans will be $70 - 20%.

Let's calculate the 20% of $70.

[tex]70\times20\%=14[/tex]

So, the discounted price of the jeans before tax is $70 - $14 = $56.

Generally, sales tax is applied to the discounted price, so let's calculate the 6% of $56.

[tex]6\%\times56=3.36[/tex]

The sales tax is $3.36.

Therefore, the cost of the pair of jeans after tax is $59.36.

To get the equation of the circle, the center of the circle and the radius are needed.

The center of the circle is the midpoint of the endpoints.

Using the midpoint formula;

[tex]\begin{gathered} M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ where: \\ x_1=-7,y_1=5 \\ x_2=-5,y_2=-1 \end{gathered}[/tex]

Thus,

[tex]\begin{gathered} M=(\frac{-7+(-5)}{2},\frac{5+(-1)}{2}) \\ M=(\frac{-12}{2},\frac{4}{2}) \\ M=(-6,2) \end{gathered}[/tex]

Hence, the coordinates of the center of the circle is (-6,2)

The length of the diameter can be gotten using the distance between two points formula;

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\begin{gathered} where: \\ x_1=-7,y_1=5 \\ x_2=-5,y_2=-1 \\ Hence, \\ d=\sqrt{(-5-(-7))^2+(-1-5)^2} \\ d=\sqrt{2^2+(-6)^2} \\ d=\sqrt{4+36} \\ d=\sqrt{40} \end{gathered}[/tex]

The diameter is twice the radius. Hence, the radius is;

[tex]\begin{gathered} r=\frac{d}{2} \\ r=\frac{\sqrt{40}}{2}=\frac{2\sqrt{10}}{2} \\ r=\sqrt{10} \end{gathered}[/tex]

Hence, the equation of the circle with center (-6,2)

[tex]with\text{ radius }\sqrt{10}[/tex]

Using the standard form of the equation of a circle;

[tex]\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ where: \\ (h,k)\text{ }is\text{ }the\text{ center} \\ r\text{ is the radius} \\ h=-6 \\ k=2 \\ r=\sqrt{10} \end{gathered}[/tex]

Hence, the equation is;

[tex]\begin{gathered} (x-(-6))^2+(y-2)^2=(\sqrt{10})^2 \\ (x+6)^2+(y-2)^2=10 \end{gathered}[/tex]

Therefore, the equation of the circle is;

From the triangle inequality theorem, the sum of the lengths any two sides must be greater than the length of the third side

So, looking at the options and looking at 4 and 5, it means that 5 is the longest side. So

[tex]\begin{gathered} 4+2=6>5 \\ 4+4=8>5 \\ 4+1=5=5 \\ 4+3=8>5 \end{gathered}[/tex]

So since 4 + 1 = 5 and 5 is not greater than 5, hence 1 cannot be the length of the 3rd side.

Using normal distribution we know that the value is P(at least 6) = 0.866.

What is Normal Distribution?A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or a Gaussian distribution.

The mean is 8.4 according to the formula:

q = 1 - p = 1 - 0.5 = 0.5Np = (13)(0.5) = 6.5 > 5Nq = (13)(0.5) = 6.5 > 5

Consequently, the normal distribution will indeed resemble the binomial.

sqrt(Npq) = sqrt(13*0.5*0.5) = 1.802 is the standard deviation.Since it's ≥ and not > and to the right, we use 6-0.5 = 5.5

Because going right from 5.5 includes 6.

P(x > 5.5) with μ = 6.5 and σ = 1.802

From the question given, we have the following data;

Height of the tree = 80 feet

Angle of elevation to the top of the tree = 68 degrees

Distance from Corey to the tree = unknown

We shall now call the unknown variable x.

With that we shall have the following diagram;

We now have a diagram detailing the triangle and the dimensions showing Corey, the tree and the eagle at the tree top.

To get a better look, Corey moves several steps away from the tree and now determines his new angle of elevation to be 41 degrees.

This can now be illustrated as follows;

From triangle EDC, we shall calculate the distance from point C to point D using trigonometric ratios. The reference angle is at point C, which means the opposite side is side ED. The adjacent side is side CD (labeled x). Using trig ratios we have;

[tex]\begin{gathered} \tan \theta=\frac{\text{opp}}{\text{adj}} \\ \tan 68=\frac{80}{x} \end{gathered}[/tex]

We cross multiply and we now have;

[tex]\begin{gathered} x=\frac{80}{\tan 68} \\ U\sin g\text{ a calculator, we have tan 68 as 2.475086}\ldots \\ x=\frac{80}{2.475086} \\ x=32.322109\ldots \\ \text{Rounded to the nearest hundredth of a foot;} \\ x=32.32ft \end{gathered}[/tex]

Looking at triangle EDB;

The reference angle is 41 which makes the opposite side ED and the adjacent side BD. To calculate the distance BD, we'll have;

[tex]\begin{gathered} \tan \theta=\frac{\text{opp}}{\text{adj}} \\ \tan 41=\frac{80}{BD} \\ We\text{ cross multiply and we now have;} \\ BD=\frac{80}{\tan 41} \\ BD=\frac{80}{0.869286} \\ BD=92.02955\ldots \\ \text{Rounded to the nearest hundredth;} \\ BD=92.03 \end{gathered}[/tex]

Take note that the distance Corey moved before he had a new angle of elevation is line segment CD which is indicated as y. Note also that

[tex]\begin{gathered} BC+CD=BD \\ CD=x=32.32ft \\ BC+32.32=92.03 \\ \text{Subtract 32.32 from both sides;} \\ BC=59.71 \end{gathered}[/tex]

The distance Corey stepped back is indicated as y (line segment BC).
