Answer: 252

Explanation:

First we need to find y.
Because there are three marks indicating that the measure of the angles are congruent, we know that all sides of the triangle are equal, so we can use that to find y.

5y-6=4y+12
y=18

Now substitute y into all the side equations:
5y-6 = 5(18)-6 = 84
4y+12 = 4(18)+12 = 84
6y-24 = 6(18)-24 = 84

Now that we know all the sides, just add these values together to get your perimeter:
84+84+84= 252

Answer:

y=18 P=252

Step-by-step explanation:

By plugging in 18 to each you get 84 for each side of the triangle. And by adding them all together the perimeter is 252.

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest interest

Westkost [7]

Answer:

Interest rate = 2.41%

Step-by-step explanation:

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest rate.

The formula to calculate the Interest rate for a Compound Interest is given as:

Solving for rate r as a decimal

r = n[(A/P)^1/nt - 1]

r = 12 × [(305.33/240.00)^1/(12)(10) - 1]

r = 0.0240996

Then convert r to R as a percentage

R = r * 100

R = 0.0240996 * 100

R = 2.41%/year

Therefore, the Interest rate = 2.41%

Find the velocity v(t)v(t) and speed ∥v(t)∥∥v(t)∥ of a particle whose motion is described by x=6t3−9t2,y=3,z=2t2−4t+2

Nesterboy [21]

Let $\mathbf p(t)=(x(t),y(t),z(t))$ denote the particle's position. Then its velocity is given by

$\mathbf v(t)=\dfrac{\mathrm d\mathbf p}{\mathrm dt}=(x'(t),y'(t),z'(t))$
$\mathbf v(t)=(18t^2-18t,0,4t-4)$

The speed is then given by the absolute value/magnitude/norm of the velocity function,

$\|\mathbf v(t)\|=\sqrt{(18t^2-18t)^2+(4t-4)^2}$

How do you write 14.8 as a mixed fraction<br> Step by step method please?

lisabon 2012 [21]

$14.8=14+0.8\\\\0.8=\dfrac{8}{10}=\dfrac{8:2}{10:2}=\dfrac{4}{5}\\\\therefore\\\\14.8=14+\dfrac{4}{5}=\boxed{14\frac{4}{5}}$
