The spider's movement is an illustration of a parabola.

(a) The equation

The spider passes through the origin.

So, we have:

[tex]\mathbf{(x,y) = (0,0)}[/tex]

The spider jumps to a maximum height of 10mm, midway 80mm.

So, the vertex is:

[tex]\mathbf{(h,k) = (40,10)}[/tex]

The equation of a parabola is:

[tex]\mathbf{y = a(x - h)^2 + k}[/tex]

So, we have:

[tex]\mathbf{0 = a(0 - 40)^2 + 10}[/tex]

Subtract 10 from both sides

[tex]\mathbf{a(0 - 40)^2 =- 10}[/tex]

[tex]\mathbf{1600a =- 10}[/tex]

Solve for a

[tex]\mathbf{a =- \frac{1}{160}}[/tex]

Substitute [tex]\mathbf{a =- \frac{1}{160}}[/tex] and [tex]\mathbf{(h,k) = (40,10)}[/tex] in [tex]\mathbf{(h,k) = (40,10)}[/tex]

[tex]\mathbf{y = -\frac{1}{160}(x - 40) + 10}[/tex]

(b) The focus, directrix and the axis of symmetry

The focus of a parabola is:

[tex]\mathbf{Focus= (h, k + p)}[/tex]

Where:

[tex]\mathbf{p = \frac{1}{4a}}[/tex]

So, we have:

[tex]\mathbf{p = \frac{1}{4 \times -1/160}}[/tex]

[tex]\mathbf{p = -\frac{160}{4}}[/tex]

[tex]\mathbf{p = -40}[/tex]

So, we have:

[tex]\mathbf{Focus = (40,10-40)}[/tex]

[tex]\mathbf{Focus = (40,-30)}[/tex]

The axis of symmetry is:

[tex]\mathbf{x = h}[/tex]

So, we have:

[tex]\mathbf{x = 40}[/tex]

The directrix is:

[tex]\mathbf{y = k - p}[/tex]

[tex]\mathbf{y = 10 + 40}[/tex]

[tex]\mathbf{y = 50}[/tex]

Answer:

120?

Step-by-step explanation:

Might be incorrect. -_-

Answer: question 1, all you had to do was divide the shpaes up by simply finding the missing numbers and separating the two shapes.

The rectangle has a area of  96

The square has a area of 16.                 if we add this up we get a area of 112

so the area is 112cm^2

Answer:

b

Step-by-step explanation:

Since it intercepts y at 4, and x at 2, we use y=ax+b and rearrange to get the equation from y=2x+4 to 2x-y=-4

Answer:

b) 2x - y = -4

Step-by-step explanation:

The y-intercept is the y-coordinate of the point (0, b) where the graph crosses the y-axis. It is also the value of y when x = 0.

The crosses the y-axis at point (0, 4). Therefore, the y-intercept, b = 4.

Next, we need to determine which of the given options matches the graph.  It helps to transform each of them into their slope-intercept form, y = mx +b:

2x - 2x + y = - 2x + 4

y = -2x + 4  (This is not the correct answer because the slope, m = -2. The given graph has a positive slope).

2x - 2x - y = - 2x - 4

-y = -2x - 4

Divide both sides by -1:

[tex]\frac{-y}{-1} = \frac{-2x - 4}{-1}[/tex]

y = 2x + 4 This is the correct answer because it matches the y-intercept (0, 4), and has a positive slope of 2.

We could easily disregard the last two options because both of their y-intercept is 0.

Therefore, the correct answer is Option b) 2x - y = - 4

Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

[tex]\mathbf{n = 10}[/tex] --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

So, the required probability is:

[tex]\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}[/tex]

[tex]\mathbf{Pr = \frac{1}{720} }[/tex]

the big triangle gives you 94 and 41 which equals 135. even though there's a line cutting off the last corner it still counts towards the 180 of the big triangle

180 - 135 = 45

now you know 2 corners of the smaller triangle

Answer:

your answer is 38 with a remainder of 1

Step-by-step explanation:

Nominator

191

Denominator

5

38.2= 38 Remainder 1

The result of 191/5 is a terminating decimal with 1 digit to the right of the decimal point.

191 divided by 5 in decimal = 38.2

191 divided by 5 in fraction = 191/5

191 divided by 5 in percentage = 3820%

On dividing 191 by 5, the remainder is 1.

The divisor is the integer that divides a given number. The resultant number is sometimes referred to as the quotient. The residual is the number that the divisor leaves after partially dividing the original integer.

Dividend = Divisor x Quotient + Remainder

On dividing 191 by 5

Step 1: Divide 191 into 5 parts: 191/5 = 38(integer part only)

Step 2: Divide the quotient you just calculated by the divisor (5).

38 × 5 = 190

Step 3: Subtract the result from the initial dividend from step 2 (191) (191):

191 - 190 = 1

Step 4: The remainder is the outcome of step 3:

1 is the result of dividing 191 by 5.

Therefore, the remainder after dividing 191 by 5 is 1.
