Answer:

$329,375

Step-by-step explanation:

first take 155000 x 4.5% = 6975

take 6975 × 25 years = 174,375.

t or the total cost is 155,000 + 174,375 = $329,375

Solve the following math problem and give me an example please C/-7+3.2=2.7

jasenka [17]

C/-7+3.2=2.7

Step 1) Add 7 to both sides because what you do to one side you must do to the other
C/<u>-7</u>+3.2=<u>2.7</u>
<u> +7 +7
</u> C/+3.2=9.7

Step 2) Subtract 3.2 from both side
C/<u>+3.2</u>=<u>9.7
</u> <u> -3.2 -3.2
</u> C/=6.5

Your answer is C=6.5<u>

Write the vector v in the form aiplusbj, given its magnitude left norm Bold v right norm and the angle alpha it makes with the

photoshop1234 [79]

Answer:

$6\sqrt{3}i-6j$

Step-by-step explanation:

Given:

The magnitude, v=12

The angle $\alpha$ it makes with the positive x-axis = $150^0$

Now for a vector (x,y)

$\alpha =tan^{-1}(\frac{y}{x} )$ ; and

$v=\sqrt{x^2+y^2}$

Therefore:

$150 =tan^{-1}(\frac{y}{x} )\\\frac{y}{x} =tan 150\\\frac{y}{x}=-\frac{\sqrt{3} }{3}$

$y=-\frac{x \sqrt{3}}{3}$

Similarly:

$v=\sqrt{x^2+y^2}\\12=\sqrt{x^2+y^2}\\12^2=x^2+y^2\\144=x^2+y^2$

$144=x^2+(-\frac{x \sqrt{3}}{3} )^2\\144=x^2+\frac{3x^2}{9} \\144=\frac{4x^2}{3}\\4x^2=144 X 3=432\\x^2=108\\x=6\sqrt{3}$

Recall that:

$y=-\frac{x \sqrt{3}}{3}\\y=-\frac{6\sqrt{3} \sqrt{3}}{3}=-6$

Therefore: $(x,y)=(6\sqrt{3}, -6)$

The vector in the form ai+bj is therefore:

$6\sqrt{3}i-6j$
