What is the rule for finding the vertex of a formula in Standard form? Use that rule to
worty [1.4K]

The vertex is the minimum or the maximum point of the parabola.

<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

<em />

The standard form of a parabola is

f(x) = ax^2 +bx + c

The x coordinate of the parabola is calculated using:

x  =-\frac{b}{2a}

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

f(\frac{b}{2a}) = a(-\frac{b}{2a})^2 + b(-\frac{b}{2a}) + c

At the end of the calculation,

x and f(x) represent the horizontal and the vertical coordinates of the vertex.

Take for instance:

f(x) = 2x^2 + 4x - 9

The x-coordinate of the vertex is:

x = -\frac b{2a}

x = -\frac 4{2 \times 2}

x = -\frac 44

x=-1

The y-coordinate is:

f(x) = 2x^2 + 4x - 9

f(-1) =2 \times (-1)^2 + 4 \times -1 - 9

f(-1) =-11

So, the vertex of f(x) = 2x^2 + 4x - 9 is (-1,11)

See attachment for illustration of vertex of f(x) = 2x^2 + 4x - 9

Bond X is a premium bond making semiannual payments. The bond pays a coupon rate of 9 percent, has a YTM of 7 percent, and has 1
timama [110]

Answer:

<h2><u>Bond X</u></h2>

current market price:

PV of face value = $1,000 / (1 + 3.5%)²⁶ = $

PV of coupon payments = $45 x 16.89035 (PV annuity factor, 3.5%, 26 periods) = $760.07

current market price = $408.84 + $760.07 = $1,168.91

price in 1 year:

PV of face value = $1,000 / (1 + 3.5%)²⁴ = $437.96

PV of coupon payments = $45 x 16.05837 (PV annuity factor, 3.5%, 24 periods) = $722.63

market price = $437.96 + $722.63 = $1,160.59

price in 3 years:

PV of face value = $1,000 / (1 + 3.5%)²⁰ = $502.57

PV of coupon payments = $45 x 14.2124 (PV annuity factor, 3.5%, 20 periods) = $639.56

market price = $502.57+ $639.56 = $1,142.13

price in 8 years:

PV of face value = $1,000 / (1 + 3.5%)¹⁰ = $708.92

PV of coupon payments = $45 x 8.31661 (PV annuity factor, 3.5%, 10 periods) = $374.25

market price = $708.92 + $374.25 = $1,083.17

price in 12 years:

PV of face value = $1,000 / (1 + 3.5%)² = $933.51

PV of coupon payments = $45 x 1.89969 (PV annuity factor, 3.5%, 2 periods) = $85.49

market price = $933.51 + $85.49 = $1,019

price in 13 years:

market price = $1,000 + $45 = $1,045

<h2><u>Bond Y</u></h2>

current market price:

PV of face value = $1,000 / (1 + 4.5%)²⁶ = $318.40

PV of coupon payments = $35 x 15.14661 (PV annuity factor, 4.5%, 26 periods) = $530.13

current market price = $318.40 + $530.13 = $847.53

price in 1 year:

PV of face value = $1,000 / (1 + 4.5%)²⁴ = $347.70

PV of coupon payments = $35 x 14.49548 (PV annuity factor, 4.5%, 24 periods) = $507.34

market price = $347.70 + $507.34 = $855.04

price in 3 years:

PV of face value = $1,000 / (1 + 4.5%)²⁰ = $414.64

PV of coupon payments = $35 x 13.00794 (PV annuity factor, 4.5%, 20 periods) = $455.28

market price = $414.64+ $455.28 = $869.92

price in 8 years:

PV of face value = $1,000 / (1 + 4.5%)¹⁰ = $643.93

PV of coupon payments = $35 x 7.91272 (PV annuity factor, 4.5%, 10 periods) = $276.95

market price = $643.93 + $276.95 = $920.88

price in 12 years:

PV of face value = $1,000 / (1 + 4.5%)² = $915.73

PV of coupon payments = $35 x 1.87267 (PV annuity factor, 4.5%, 2 periods) = $65.54

market price = $915.73 + $65.54 = $981.27

price in 13 years:

market price = $1,000 + $35 = $1,035

PLZZZ ANSWER!! Answers for points will be reported.
Lisa [10]

Answer:

  • 272.6

Step-by-step explanation:

This is an isosceles triangle with base of 21 and sides of 28.

<u>Area formula</u>

  • A = 1/2bh

<u>Find height:</u>

  • h = \sqrt{28^2 - (21/2)^2}  = \sqrt{673.75} = 25.96

<u>Area:</u>

  • A = 1/2(25.96)(21) = 272.6 (rounded)
