Jake dives from a diving board that is 18 feet off the ground. He reaches a maximum height of 26 feet after 2 seconds. What is the standard and vertex formula of this quadratic equation and in how many seconds with Jake hit the water?

Answers

Answer:

The time it will take Jake to hit the water ia approximately 4.46 seconds

Step-by-step explanation:

The given parameters in the question are; feet

The height off the ground, of the diving board from which Jake dives, h₀ = 18 feet

g = The acceleration due to gravity

The maximum height Jake reaches, h = 26 feet

The time Jake takes to reach maximum height = 2 seconds

We have;

h = h₀ + u·t + 1/2·g·t²

v² = u² - 2·g·(h - h₀)

v = u - gt

u = gt

Where;

v = The final velocity

u = The initial velocity

t = The time taken

u = 9.81 × 2 = 19.62 m/s

The vertex form of a quadratic equation is f(x) = a(x - h)² + k², with the vertex = (h, k)

Substituting the values, gives;

26 = 18 + u·t - 1/2 × 9.81 × t²

8 = 19.62·t - 1/2 × 9.81 × t² = 19.62·t - 4.905·t²

19.62·t - 4.905·t² - 8 = 0

Therefore, the standard form is  -4.905·t² + 19.62·t - 8 = 0

The coordinate of the vertex, is (2, 8), the vertex form is therefore;

-4.905(t - 2)² + 8

2) The time it will take Jake to hit the water is given as follows;

The height at which Jake meets the water = -18 feet from initial height

∴ -4.905·t² + 19.62·t - 8 = -18

-4.905·t² + 19.62·t - 8 + 18 = 0

-4.905·t² + 19.62·t + 10 = 0

t² - 4·t - 2.04 = 0

By the quadratic formula, we have;

t = (4 ± √((-4)² - 4 × 1 × -2.04))/(2×1)

t ≈ 4.46 seconds or t ≈ -0.46 seconds

∴ t ≈ 4.46 seconds

The time it will take Jake to hit the water ≈ 4.46 seconds.

Exponential function f is represented by the table. x 0 1 2 3 4 f(x) 868 292 148 112 103 Function g is an exponential function passing through the points (0,800) and (4,0). Which statement correctly compares the two functions? A. Both functions are decreasing on [0, 4], but function g decreases at a faster rate. B. Only function g is decreasing on [0, 4], and only function f is positive on that interval. C. Both functions are decreasing on [0, 4], but function f decreases at a faster rate. D. Only function f is decreasing on [0, 4], and both functions are positive on that interval.

Answers

Answer:

The correct option is;

A. Both functions are decreasing on [0, 4], but function g decreases at a faster rate

Step-by-step explanation:

The given data are;

Table representing the exponential function f

x         [tex]{}[/tex]                      f(x)

0          [tex]{}[/tex]                    828

1          [tex]{}[/tex]                     292

2         [tex]{}[/tex]                      148

3          [tex]{}[/tex]                     112

4          [tex]{}[/tex]                     103

The points through which the exponential function g passes = (0, 800) and (4, 0)

Therefore, we have that both functions are decreasing on [0, 4]

The change in the values of f(x) on [0, 4] = 828 - 103 = 725

The change in the values of 8(x) on [0, 4] = 800 - 0 = 800

Therefore, g(x) decreases faster than f(x) on [0, 4] than f(x)

A line passes through the points (2,-4) and (6,10). What is the equation of the line?

Answers

Answer:

y = [tex]\frac{7}{2}[/tex] x - 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (6, 10)

m = [tex]\frac{10+4}{6-2}[/tex] = [tex]\frac{14}{4}[/tex] = [tex]\frac{7}{2}[/tex] , thus

y = [tex]\frac{7}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, - 4) , then

- 4 = 7 + c ⇒ c = - 4 - 7 = - 11

y = [tex]\frac{7}{2}[/tex] x - 11 ← equation of line

Step-by-step explanation:

suppose a parabola has an axis of symmetry at x = -8, a maximum height of 2, and passes through the point (-7, -1). Write the equation of the parabola in vertex form

Answers

Answer:

           f(x) = - 3(x + 8)² + 2

Step-by-step explanation:

f(x) = a(x - h)² + k   - the vertex form of the quadratic function with vertex    (h, k)

the axis of symmetry at x = -8 means h = -8

the maximum height of 2 means  k = 2

So:

f(x) = a(x - (-8))² + 2

f(x) = a(x + 8)² + 2   - the vertex form of the quadratic function with vertex   (-8, 2)

The parabola passing through the point (-7, -1) means that if x = -7 then        f(x) = -1

so:

    -1 = a(-7 + 8)² + 2

 -1 -2 = a(1)² + 2 -2

      -3 = a

Threfore:

The vertex form of the parabola which has an axis of symmetry at x = -8, a maximum height of 2, and passes through the point (-7, -1) is:

                                 f(x) = -3(x + 8)² + 2

[tex]y=-x+9[/tex]

Step-by-step explanation:

This is asking you to write the equation in slope-intercept form:

[tex]y=mx+b[/tex]

where:

m is the slopeb is the y-interceptx and y are any corresponding coordinate points (x,y)

You need to find the slope of the two given points using:

[tex](x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope[/tex]

Insert the values:

[tex](4_{x_{1}},5_{y_{1}})\\\\(-6_{x_{2}},15_{y_{2}})\\\\\frac{15-5}{-6-4} =\frac{10}{-10} =-\frac{10}{10} =-1[/tex]

The slope of the given line is -1. Insert this value into the equation:

[tex]y=-1x+b\\\\y=-x+b[/tex]

Now insert one of the given coordinate points as x and y to solve for b:

[tex](4_{x},5_{y})\\\\5=-4+b\\\\5+4=-4+4+b\\\\9=b[/tex]

The y-intercept is 9. Insert the value:

$36.35
d.
$24.27



Please select the best answer from the choices provided


A
B
C
D

Answers

Answer:

The answer is B

Step-by-step explanation:

I just took the quiz on Edge

Amount Zalia pay all total for her day at the science museum is,

⇒ $37.68.

What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Now, Each admission ticket is 12.50 plus tax.  

Here, 2 tickets at 12.50 each is

2(12.50) = 25

Hence, Tax for this is 7.25%;

7.25% = 7.25/100 = 0.0725;

So,

25+25(0.0725)

= 25(1.0725)

= 26.82

For lunch, she spent

5.95+1.25+1.69 = $8.89.

Tax for this would be 0.0725(8.89) = $0.64

15% tip on this would be 8.89(0.15) = $1.33

This gives us

8.89+0.64+1.33 = $10.86 for lunch.

Hence, This is a total of,

26.82+10.86 = $37.68.

To solve the equation 7k - 14 = 42, isolate the variable k by performing the necessary steps in a commanding tone.

Step 1: Add 14 to both sides of the equation to eliminate the -14 term on the left side:

7k - 14 + 14 = 42 + 14

On simplifying:
