Answer:

D. $y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}$

Step-by-step explanation:

Let be $y = \Sigma_{i = 0}^{4} \left[5\cdot \left(\frac{1}{3} \right)^{i}\right]$ . To find the equivalent expression we must use the following property:

$y = c\cdot \Sigma_{i = 0}^{n} p(x) = \Sigma_{i=0}^{n} [c\cdot p(x)]$ (1)

Based on this fact, we find the following equivalence:

$y = 5\cdot \Sigma_{i=0}^{4} \left(\frac{1}{3} \right)^{i}$

Hence, the correct answer is D.

Marrrta [24]

Answer:

about 8 classes

Step-by-step explanation:

convert 6 3/4 to a fraction: 27/4

3/4 can go into 27/4 9 times, but with time in between, you should only be able to have 8 classes instead of 9

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0)

zhenek [66]

Answer:

(7, 3)

Step-by-step explanation:

Using the midpoint formula

M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}

X = ax1+bx2/a+b

X = -5(1)+3(11)/1+3

X = -5+33/4

X = 28/4

X = 7

Y = ay1+by2/a+b

Y = 1(12)+3(0)/1+3

Y = 12/4

Y = 3

Hence the coordinate of P is at (7, 3)

Given that ABC is a right triangle.

The length of AC = 10 and AB = 17

We need to determine the m∠B

<u>The measure of ∠B:</u>

The side opposite to ∠B is AC and the hypotenuse of the triangle is AB

The m∠B can be determined using the trigonometric identity,

$sin B=\frac{opp}{hyp}$

where $opp=AC$ and $hyp=AB$

Substituting, we get;

$sin B=\frac{AC}{AB}$

Substituting the values, we get;

$sinB=\frac{10}{17}$

$sin B=0.588$

Taking $sin^{-1}$ on both sides of the equation, we have;

$B=sin^{-1}(0.588)$

$B=36.015^{\circ}$

Rounding off to the nearest tenth, we get;

$B=36.0^{\circ}$

Hence, the measure of ∠B is 36.0°
