A jumping spider's movement is modeled by a parabola. The spider makes a single
jump from the origin and reaches a maximum height of 20 mm halfway across a horizontal distance of 160 mm.
Part A: Write the equation of the parabola in standard form that models the spider's jump. Show your work. (4 points)
Part B: Identify the focus, directrix, and axis of symmetry of the parabola. (6 points)
Answer:
A. (x - 80)² = -320(y = 20)
B. Focus: (80, -60)
Directrix: y = 100
Axis of symmetry: x = 80
Step-by-step explanation:
Part AIf the spider's movement is modeled by a parabola, and its maximum height is 20 mm halfway across a horizontal distance of 160 mm, then:
x-intercepts = (0, 0) and (160, 0)Vertex = (80, 20)Standard form of a parabola with a vertical axis of symmetry:
[tex]\boxed{(x-h)^2=4p(y-k) \quad \textsf{where}\:p\neq 0}[/tex]
If p > 0, the parabola opens upwards, and if p < 0, the parabola opens downwards.
[tex]\textsf{Vertex}=(h, k)[/tex][tex]\textsf{Focus}=(h,k+p)[/tex][tex]\textsf{Directrix}:y=(k-p)[/tex][tex]\textsf{Axis of symmetry}:x=h[/tex]Substitute one of the x-intercepts and the vertex into the formula and solve for p:
[tex]\implies (0-80)^2=4p(0-20)[/tex]
[tex]\implies (-80)^2=4p(-20)[/tex]
[tex]\implies 6400=-80p[/tex]
[tex]\implies p=-80[/tex]
Substitute the found value of p and the vertex into the formula to create the equation of the parabola in standard form:
[tex]\implies (x-80)^2=4(-80)(y-20)[/tex]
[tex]\implies (x-80)^2=-320(y-20)[/tex]
Part BGiven:
h = 80k = 20p = -80[tex]\begin{aligned}\textsf{Focus}&=(h,k+p)\\&=(80,20-80)\\&=(80,-60)\end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Directrix}:y&=(k-p)\\ \implies y&=(20-(-80))\\ \implies y&=100\end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Axis of symmetry}:x&=h\\ \implies x&=80\end{aligned}[/tex]

what the slopes and y intercepts for both of these?
Answer:
First graph: slope = [tex]\frac{2}{3}[/tex] & y-intercept = (0, -1). Second graph: slope = 2 & y-intercept = (0,2)Step-by-step explanation:
They're both linear graphs, so they both follow the formula y = mx + b.
The y-intercept is when the graph crosses the y-intercept, so when x = 0.
First graph:
(x, y₁) = (0, -1)(x₂, y₂) = (-3, -3)Slope(m): [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} } =\frac{-3-(-1)}{-3-0} =\frac{-2}{-3} =\frac{2}{3}[/tex]
y-intercept(b): (0, -1)
Second graph:
(x, y₁) = (0, 2)(x₂, y₂) = (-3, -4)Slope(m): [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} } =\frac{-4-2}{-3-0} =\frac{-6}{-3} =2\\[/tex]

The measure of the exterior angle of the triangle is
Answer:
exterior angle = 139°
step-by-step explaination:(I'm using "X" instead of "2")
to find the exterior angle, find the interior angle first and then use the straight line.
interior angle = 180° therefore,
75° + 64° + X = 180
139° + X = 180°
X = 180° - 139°
X = 41° (not the answer)
a straight line = 180°
X = 41°
Y - the exterior angle
41° + Y = 180°
Y = 180° + 41°
Y = 139°
hope this is clear :)

The dimensions of the rectangular paint of perimeter 104.09 inches are given as follows:
Height: 28.88 inches.Width: 23.16 inches.How to obtain the perimeter of a rectangle?The perimeter of any polygon, including a rectangle, is given by the sum of all the lengths of the outer edges of the figure.
Hence, for a rectangle of height h and width w, the perimeter is given by twice the sum of these dimensions, hence it is given as follows:
P = 2(h + w).
In this problem, the perimeter has the value given as follows:
P = 104.09 inches.
Hence:
2(h + w) = 104.09
h + w = 104.09/2
h + w = 52.045 inches.
The painting is 5.72 inches taller than it is wide, hence:
h = 5.72 + w.
Then the height is obtained as follows:
5.72 + w + w = 52.045
2w = (52.045 - 5.72)
w = (52.045 - 5.72)/2
w = 23.16 inches.
Then the height of the rectangular painting is given as follows:
h = 5.72 + w = 5.72 + 23.16 = 28.88 inches.

Assume the $26,000 Treasury bill, 5% for 13 weeks. Calculate the effective rate of interest.
Note: Use calendar year. Round your answer to the nearest hundredth percent.
Effective rate of interest
Simple interest of $325 was accrued on a principal of $26,000.00 for a period of 0.25 years (13 weeks) at a rate of 5% per year, bringing the total amount due to $26,325.00 (principal plus interest).
What is simple interest?Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, so a creditor will only charge interest on the principal sum, and a borrower will never be required to pay additional interest on the interest that has already accrued.
Here,
A = $26,325.00
I = A - P = $325.00
A is equal to P(1 + rt).
The first step is to convert R percent to r a decimal, which is equal to R/100 = 5%/100 = 0.05 per year.
For ease, let's convert time to years: 13 weeks / 52 weeks / year = 0.25 years.
How to resolve our equation
A = 26000(1 + (0.05 × 0.25)) = $26,325.00
Simple interest accrued on a principal of $26,000.00 at a rate of 5% per year for 0.25 years (13 weeks) totaling $26,325.00 (principal plus interest).

what ticket price would maximize revenue?
As per the concept of system of linear equations, the maximum revenue of this basket ball match is $3.4
Linear equation:
Linear equation refers the one variable is an equation in which there is only one variable present. And it is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.
Given,
A baseball team plays in a stadium that holds 66000 spectators. With the ticket price at $10 the average attendance has been 28000. When the price dropped to $7, the average attendance rose to 33000. Assume that attendance is linearly related to ticket price.
Here we need to find the ticket price would maximize revenue.
In order to find the ticket price for the maximum revenue,
We have to identify the details from the given question,
Total seating capacity = 66,000
When ticket price $10 then the attendance 28,000
When ticket price $7 then the attendance 33,000
Let us consider the x be the maximum revenue ticket price.
Now, to solve this we have to find the slope for the equation,
That is,
=> m = (33000 - 28000)/(7 - 10)
=> m = 5000/-3
=> m = -5000/3
=> m = 1666.6
Then the revenue equation is written as,
=> y = (10 - x) * (28,000 + 1666.6x)
=> y = 280000-11334x-1666.6x²
If we plot the this function into the graph, then we get the graph like the following.
Therefore, the solution of the graph is 3.4.

Find the average rate of change of f(x) = -x² + 3x + 1 from x=2 to x = 5.
Simplify your answer as much as possible.
Answer:
The average rate of change is: -4
Step-by-step explanation:
So to solve this we just need to plug our numbers into the formula. We are using the formula f(b) - f(a)b - a where “a” and “b” are our numbers. So we are given the intervals x=2 and x=5. When we see that we can rewrite it as (2,0) and (5,0). This is because when it is telling us just “x” we know “y” (the second number in the parentheses) is 0. So just plugging in the numbers we get: (-(5)2+3(5)+1)-(-(2)2+3(2)+1)(5 - 2). Solving it we get -4.

Considering the definition of a line, the equation of the line that passes through the point (-2, 1) and has a slope of 1/3 is y= 1/3x + 5/3.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Line in this caseIn this case, you know:
The line has a slope of 1/3.The line passes through the point (-2, 1).Substituting the value of the slope m, you get:
y= 1/3x + b
Replacing the value of the point in previous expression, the value of the ordinate to the origin b can be obtained:
1= 1/3× (-2) + b
1= - 2/3 + b
1 + 2/3= b
5/3= b

line m passes through the points (-4, 3) and (-4, 7) what is the slope of the line that is perpedicular to the line m
Answer:
The slope is 4 and the equation is y = 4x + 18
Step-by-step explanation:
Okay, so you start by solving for the slope. The formula for slope is
m = y1-y2 over x1-x2 (it looks lke a fraction)
then you plug in your coordinates, so it becomes:
m = 7-3 over -4 - (-4) which then you get your slope as 4, but because it has to be perpendicular, the slope becomes -1/4. this is because the slope has to be the reciprocal and the opposite sign to be perpendicular.
Then, you can continue to create the equation by using point-slope form, which is y - y1 = m (x-x1) (y1 and x1 are from the coordinates btw)
so the point-slope equation is:
y - 3 = -1/4 (x + 4)
y - 3 = -1/4x - 1
+3 +3
y = -1/4x + 2 (this is your equation in slope - intercept form)
I hope this helps!!

in a chocolate factory a machine takes a 1 kg block of chocolate. It then divides it into rectangles each weight 10g
The number of division that will take place when the chocolate factory a machine takes a 1 kg block of chocolate is 100.
How to calculate the value?From the information, in the chocolate factory a machine takes a 1 kg block of chocolate and then divides it into rectangles each weight 10g.
It is important to note that:
1000 grams = 1 kilograms
Therefore, since the chocolate is divided into 10g, this will be:
= Total grams / 10 gram
= 1000g / 10g
= 100
Therefore, there will be 100 division.

how do you know that 2 to the power of 3 x 3 is not a common multiple
Answer:
512
Step-by-step explanation:
A common multiple is defined as a whole number, a shared multiple of each set of numbers. The multiples common to two or more numbers are called the common multiples of those numbers.
OML I just gave u the answer do I need to put this in simple terms for you since u don't understand - 2 to the power of 3 x 3 is 512 and that is not a whole number a common multiple is defined as a whole number and for 512 to be an integer it has to be a whole number. UNDERSTAND NOW???
