Can anyone help me with this?? 100 points

Answers

Answer:

$1154.42

Step-by-step explanation:

Given:

Deposit amount P = $10000Interest rate r = 5.5% or 0.055Time t = 2 yearsNumber of compounds n = 4

The interest is:

P*(1 + r/n)^(nt) - P = 10000(1 + 0.055/4)^8 - 10000 = 11154.42 - 10000 = 1154.42

Apply compound interest formula

Amount

P(1+r/n)^nt10000(1+0.055/4)^4(2)11154.42

Answers

Answer:

First option

Step-by-step explanation:

Hi there!

The "constant additive rate of change" means a constant slope.

The slope is [tex]\displaystyle\frac{change \hspace{4} in \hspace{4} y}{change \hspace{4} in \hspace{4} x}[/tex].

First of all, if the slope is constant, then we know immediately that it must be a linear function, a line. The change in y is forever the same according to the change in x. Knowing this, the second option is for-sure wrong (it's not a straight line).

Now, let's look at the first option. It is a linear function, which means it has a constant slope. However, we're given that the slope is [tex]-\displaystyle \frac{1}{4}[/tex]. This means that for a line, whenever it travels 4 units to the right, it travels 1 unit down (it travels down whenever the slope is negative and up whenever the slope is positive).

This is the exact case for the first option. Look at the point (-2,2) on the line. When we move 4 units to the right of that point, The line would have moved 1 unit down. We would reach the point (2,1).

Therefore, the correct answer would be the first option.

I hope this helps!

Find all of the points of the form (x, −x) which are 7 units from the origin.
(x, y) =

(smaller x-value)

(x, y) =

(larger x-value)

Answers

Answer:

(-7, 0) and (7, 0)

Step-by-step explanation:

All the points that are 7 units from the origin are on the circle:

x² + y² = 7²

The maximum and minimum values of x obtained when y = 0:

x² = 7² √x² = √7²x = ± 7

So

min x = -7 and max x = 7

The points are:

(-7, 0) and (7, 0)

The equation will be

[tex]\\ \sf\longmapsto \sqrt{x^2+y^2}=7[/tex]

[tex]\\ \sf\longmapsto x^2+y^2=7[/tex]

If y be 0

[tex]\\ \sf\longmapsto x^2+0=7^2[/tex]

[tex]\\ \sf\longmapsto x^2=49[/tex]

[tex]\\ \sf\longmapsto x=\sqrt{49}[/tex]

[tex]\\ \sf\longmapsto x=\pm 7[/tex]

Now the points are

Answers

9514 1404 393

Answer:

A'(0, 0), B'(-6, -18), C'(0, -12)

Step-by-step explanation:

Rotation 180° is the transformation ...

  (x, y) ⇒ (-x, -y)

Dilation by a factor of 3 is the transformation ...

  (x, y) ⇒ (3x, 3y)

The two transformations together can be described by ...

  (x, y) ⇒ (-3x, -3y)

That is, the coordinates of A, B, C are each multiplied by -3. The image vertices are ...

  A' = -3A = A'(0, 0) . . . . . . . . the center of rotation and dilation is invariant

  B' = -3B = B'(-6, -18)

  C' = -3C = C'(0, -12)

Any dilated figure will not be congruent to the original. The triangles are similar.

[tex]$\csc t-\frac{2}{\sqrt{3} }[/tex]

[tex]\sec t=2[/tex]

[tex]\cot t=\frac{1}{\sqrt{3} }[/tex]

Step-by-step explanation:

Given:

[tex]\sec(t)=2[/tex]

The terminal point of [tex]t[/tex] is in Quadrant [tex]IV[/tex]

Step 1:  

To find the values of trigonometric functions of t

[tex]\sec(t)=\frac{H}{A}[/tex]

[tex]=\frac{2}{1}[/tex]

Analyze the figure and find the value of O

[tex]t[/tex] [tex]IV[/tex]

[tex]O=\sqrt{2^{2}-1^{2} }[/tex]

[tex]=\sqrt{4-1}[/tex]

[tex]=\sqrt{3}[/tex]

Step 2:

[tex]$\sin t=-\frac{O}{H}[/tex]

[tex]=-\frac{\sqrt{3} }{2}[/tex]

[tex]\cos t=\frac{A}{H}[/tex]

[tex]=\frac{1}{2}[/tex]

[tex]\tan t=-\frac{O}{A}[/tex]

[tex]=-\sqrt{3}[/tex]

[tex]$\csc t=-\frac{H}{O}[/tex]

[tex]=-\frac{2}{\sqrt{3} }[/tex]

[tex]\sec t=\frac{H}{A}[/tex]

[tex]=\frac{2}{1}[/tex]

[tex]\cot t=-\frac{A}{O}[/tex]

[tex]=\frac{1}{\sqrt{3} }[/tex]
