Answer:

$\frac{5}{81}$

Step-by-step explanation:

To evaluate f(4) substitute x = 4 into f(x)

f(4) = 5 × $(\frac{1}{3 )} ^{4}$ = 5 × $\frac{1}{3^{4} }$ = $\frac{5}{81}$

Answer:

m<M = 50°

Step-by-step explanation:

m<M +m<P +m<V=180° (sum of the interior angles of the triangle)

x+78+52°=180°

=>x+130= 180°

=>x=180°-130°

=>x= 50°

Step-by-step explanation:

The angle between vectors is given by

$\cos{\theta} = \dfrac{\vec{\textbf{a}}\cdot \vec{\textbf{b}}}{|\vec{\textbf{a}}||\vec{\textbf{b}}|}$

The magnitudes for the vectors are as follows:

$|\vec{\textbf{a}}| = \sqrt{a_x^2 + a_y^2 + a_z^2}$

$\:\:\:\:\:\:\:=\sqrt{(2)^2 +(-5)^2 + (3)^2} = 6.16$

$|\vec{\textbf{b}}| = \sqrt{b_x^2 + b_y^2 + b_z^2}$

$\:\:\:\:\:\:\:= \sqrt{(3)^2 + (1)^2 + (4)^2} = 5.10$

The dot product between the vectors is

$\vec{\textbf{a}}\cdot \vec{\textbf{b}} = (2)(3) + (-5)(1) + (3)(4) = 13$

Therefore, the angle between the two vectors is

$\cos{\theta} = \dfrac{\vec{\textbf{a}}\cdot \vec{\textbf{b}}}{|\vec{\textbf{a}}||\vec{\textbf{b}}|} = \dfrac{13}{(6.16)(5.10)}$

$\theta = 65.56°$

Justin earns 5% commission on his real estate sales. One year, his total commission was 35,750. What were his sales for that yea

Ymorist [56]

The sales for the particular year was: 715000

Step-by-step explanation:

We will use the percentage formula for finding the total sales.

Given

Commission Rate = 5%

Commission = 35750

Let x be the sales

So,

$Commission=Sales * 5\%\\35750=x * \frac{5}{100}\\35750=x * 0.05\\x = \frac{35750}{0.05}\\x= 715000$

The sales for the particular year was: 715000
