Assuming "y" is north, the y-component is
.. (4.00 m)*sin(23.5°) ≈ 1.59 m

Um I am not sure you copied the question correctly. But if it means to say Y= 3X + 4. Then dividing by 1 always does nothing. F(x) has no change

Help with those three please!!
Scilla [17]

Answer:

Part 1) Option A. The axis of symmetry is x=4

Part 2) Option C. minimum

Part 3) Option A. (4,-4)

Part 4) Option B. (2,0) and (6,0)

Step-by-step explanation:

we have

f(x)=x^{2}-8x+12

Part 1) What is the axis of symmetry of the parabola described by the equation above?

we know that

The equation above is a vertical parabola open upward

The axis of symmetry is the x-coordinate of the vertex

Find the vertex of the parabola (convert the equation in vertex form)

f(x)-12=x^{2}-8x

f(x)-12+16=x^{2}-8x+16

f(x)+4=x^{2}-8x+16

f(x)+4=(x-4)^{2}

f(x)=(x-4)^{2}-4 ----> equation in vertex form

The vertex of the parabola is (4,-4)

so

The axis of symmetry is x=4

Part 2) The vertex of the equation above is also

we know that

The equation above is a vertical parabola open upward

therefore

The vertex is a minimum

Part 3) What is the vertex of the parabola described by the equation above

we know that

The equation of the parabola into vertex form is equal to

f(x)=(x-4)^{2}-4

therefore

The vertex of the parabola is (4,-4)

Part 4) What are the  x-intercepts of the parabola described by the equation above

we know that

The x-intercepts are the values of x when the value of y is equal to zero

so

f(x)+4=(x-4)^{2}

f)x)=0

so

4=(x-4)^{2}

take square root both sides

(x-4)=(+/-)2

x=4(+/-)2

x=4(+)2=6

x=4(-)2=2

therefore

The x-intercepts are

(2,0) and (6,0)

Solve these compound interest problems and round your answer to the nearest 100th.
sergiy2304 [10]

Answer:

$2,895.19

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance </em>

<em>r = interest rate </em>

<em>n = number of times compounded annually </em>

<em>t = time </em>

First, change 8% into its decimal form:

8% -> \frac{8}{100} -> 0.08

Now lets plug in the values into the equation:

A=1,800(1+\frac{0.08}{4} )^{6(4)}

A=2,895.19

The final amount for this investment is $2,895.19
