Answers

To find the answer you turn the percent into a decimal so it is .30 instead of 30% then multiply .30 and 40 and you get your answer, 12.

Answer:

Step-by-step explanation:

1. f(-2) = 6 * 1/3^-2

f(-2) = 6 * 9

f(-2)  = 54

2. y = -3 * 4^3

y = -3 x 64

y = -192

3. f(4) = 1/4 * 2^4

f(4) = 1/4 * 16

f(4) = 4

PLEASE HELP ME!!!! 50 points! Given the points C(-1, -3) and D(5, 6), find the coordinates of the point E on directed line segment CD that partitions CD into the ratio 2 to 1.

A. (1, 0)

B. (3, 3)

C. (-3, 3)

D. (2, 1.5)

Answers

Answer:

B. (3,3)

Step-by-step explanation:

In order to find the coordinates of point E that partitions the line segment CD into a ratio of 2:1, we can use the following formula for finding the coordinates of a point that divides a line segment in a given ratio:

For a line segment with endpoints A(x1, y1) and B(x2, y2), and a division ratio of m:n, the coordinates of the point E(x, y) that divides the line segment in this ratio are given by:

\sf x =( (m* x_2 + n* x_1) )/((m + n))

\sf y =( (m* y_2 + n* y_1) )/((m + n))

In this case, we want to divide the line segment CD into a ratio of 2:1, so m = 2 and n = 1.

Wehave the coordinates of C(-1, -3) and D(5, 6).

Using the formula:

\begin{aligned} x &\sf =( (2* 5 + 1* (-1)))/( (2 + 1)) \n\n &\sf = (10-1)/(3)\n\n &\sf = (9)/(3)\n\n &\sf = 3 \end{aligned}

and

\begin{aligned} y &\sf =( (2* 6 + 1* (-3)) )/( (2 + 1)) \n\n &\sf = (12-3)/(3) \n\n &\sf = (9)/(3)\n\n &\sf = 3 \end{aligned}

So, the coordinates of point E that partitions the line segment CD into a ratio of 2:1 are E(3, 3).

So, the answer is B. (3,3)

Three consecutive even integers have a sum of 18. Find the integers.

Answers

Let
x = first consecutive even
x + 2 = second consecutive even
x + 4 = third consecutive even

Based on the problem, we equate
x + (x + 2) + (x + 4) = 18
Solving for x,
3x + 6 = 18
3x = 18 - 6
3x = 12
x = 12/3
x = 4
and x + 2 = 4 + 2 = 6
and x + 4 = 4 + 4 = 8

Therefore, the three consecutive even integers are 4, 6, 8.
