Which of the following points does not lie on the graph of y = log3x?(0, 1)
(27, 3)
(1, 0)

Answers

Answer 1

Answer:

Answer:

(0,1) doesn't lie on the graph.

Step-by-step explanation:

We have been given the logarithmic equation $y=\log_3(x)$

We can check which point lie on the graph of the given function by substituting x coordinates in the equation and find the corresponding y coordinate.

For x = 0

$y=\log_3(0)\n\ny=\log_30$

The value of log 0, is undefined, Hence, we'll not get a real value for this x value.

Hence, (0,1) doesn't lie on the graph.

For x = 27

$y=\log_3(27)\n\ny=\log_33^3\n\ny=3\log_33\n\ny=3$

Hence, (27,3) lie on the graph.

For x = 1

$y=\log_3(1)\n\ny=0$

Hence, (1,0) lie on the graph.

Therefore, (0,1) doesn't lie on the graph.

A plane takes off at an angle of elevation of 15° and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?

Answers

The angle of elevation is 15 degrees. This angle is measured from the horizontal. This problem requires us to review our triangle relationships. This triangle is a right triangle. That means to answer this problem we have to noe the relationship sin(angle) = opposite/hypotenuse. The 3000 is the hypotenuse measurement and we are to find the opposite. 3000sin(15) = 776.45m.

Which points are solutions to the linear inequality; y < 0.5x + 2?

Answers

Answer:

A) $(-3,-2)$

C) $(-1,-2)$

E) $(1,-2)$

F) $(1,2)$

Step-by-step explanation:

we have

$y<0.5x+2$

The options are the points

$(-3,-2)$ , $(-2,1)$ , $(-1,-2)$ , $(-1,2)$ , $(1,-2)$ , $(1,2)$

we know that

If a ordered pair is a solution of the inequality

then

the ordered pair must be satisfy the inequality

Verify

Point A) $(-3,-2)$

Substitute the value of x and value of y in the inequality an compare

$-2<0.5(-3)+2$

$-2<0.5$ -------> is true

The ordered pair $(-3,-2)$ is a solution of the inequality

Point B) $(-2,1)$

Substitute the value of x and value of y in the inequality an compare

$1<0.5(-2)+2$

$1<1$ -------> is not true

The ordered pair $(-2,1)$ is not a solution of the inequality

Point C) $(-1,-2)$

Substitute the value of x and value of y in the inequality an compare

$-2<0.5(-1)+2$

$-2<1.5$ -------> is true

The ordered pair $(-1,-2)$ is a solution of the inequality

Point D) $(-1,2)$

Substitute the value of x and value of y in the inequality an compare

$2<0.5(-1)+2$

$2<1.5$ -------> is not true

The ordered pair $(-1,2)$ is not a solution of the inequality

Point E) $(1,-2)$

Substitute the value of x and value of y in the inequality an compare

$-2<0.5(1)+2$

$-2<2.5$ -------> is true

The ordered pair $(1,-2)$ is a solution of the inequality

Point F) $(1,2)$

Substitute the value of x and value of y in the inequality an compare

$2<0.5(1)+2$

$2<2.5$ -------> is true

The ordered pair $(1,2)$ is a solution of the inequality

If we have twice as many blue marbles as green, we have 3 parts; 2 parts blue and 1 part greens. Therefore, 1/3 of the marbles are green

54/3=18
At least 18 of the marbles are green

Step-by-step explanation:

A certain office supply store stocks 2 sizes of self-stick notepads, each in 4 colors: blue, green, yellow, or pink. The store packs the notepads in packages that contain either 3 notepads of the same size and the same color or 3 notepads of the same size and of 3 different colors. If the order in which the colors are packed is not considered, how many different packages of the types described above are possible?A. 6.
B. 8.
C. 16.
D. 24.
E. 32.

Answers

Answer:

Option C. 16

Step-by-step explanation:

Number of differents colors = 4

Number of differents sizes = 2

Case 1: 3 notepads of the same size and the same color:

If we have a package with the same size and the same color, the number of possible packages is:

N° packages = 4(colors)*2(sizes) = 8

Case 2: 3 notepads of the same size and different colors:

In this case, to calculate the number of possible permutations of packages without repetitions we need to use the following equation:

$C_(n)^[p} = (n!)/(p!(n-p)!)$

where p: is the number of colors for each package = 3, and n: is the total number of colors = 4.

$C_(4)^[3} = (4!)/(3!(4-3)!) = (4*3*2*1)/(3*2*1) = 4$

This number calculated is for one size, if the have two different sizes the number of possible packages is:

N° packages = 4(colors)*2(sizes) = 8

Therefore, the total number of different possible packages is:

N° packages = case 1 + case 2 = 8 + 8 = 16

So, the correct answer is option C = 16.

I hope it helps you!
