Which of the 3 graphs represent [tex]\frac{1}{2x} +9y[/tex]?

Select 3 graphs then attach them in your answer.

Answers

Answer: 1st Graph.

The first graph represents the problem because 1/2x is the x intercept, so 1/2 intersects the x-axis.

Basically, the x intercepts are [tex](\frac{\sqrt{2} }{2},0)(-\frac{\sqrt{2} }{2},0)[/tex]

They're aren't any Y intercepts because it will never intersect the y-axis, so it must be parallel.

Hence, the 1st Graph represents your equation.

Step-by-step explanation:

Im not sure if im wrong im very very sorry!

have a great day!

Area of the square is

s=b*h
s=16*16
s=256

Area of circle
c=pi*r^2
c=pi*8^2
c=200.96

Now we need to minus the area of the circle off of the area of the square

TA=s-c
TA=256-200.96
TA=55.04 ft^2

So the total area is 55.04 ft^2

For C:

you would need to measure your circular thing all the way across it in the centimete side of a ruler and you would find your answer.

For D:

you need to find the area of your circle and make an expression. Like let’s say the area of your circular object was 4, your expression would be 2+2=4

The height of a mountain is 24,000 feet. Of this height, 22,000 feet is above sea level and 2,000 feet is below sea level. Which set of integers represents the heights of the mountain above and below sea levels? pick the right expression that equal the word problem.
A. { 22,000, 2,000}

B. { 22,000, 2,000}

C. { 22,000, 2,000}

Answers

The answer is A {+22,000 -2,000}

This is because sea level is counted as 0 on a topographical map and any distance below sea level is counted in -ft. So if you the problem is amount above sea level to amount below sea level then you have 22,000 above sea level which would be +22,000 ft. And two thousand below. Then you just put that in the brackets “{}” and you are done.

yup i’m pretty sure he’s correct

1. Four different numbers that with a median of 4.5 are 3, 4, 5, 6.

2. Six different numbers that satisfy this condition: -5, -2, -1, 1, 2, 5.

1. To have a median of 4.5, we need a set of numbers that is arranged in increasing order.

Here are four different numbers that satisfy this condition: 3, 4, 5, 6.

When arranged in ascending order, the median of these numbers is indeed 4.5 since it is the average of the two middle numbers, 4 and 5.

2. To have a median of 0, we can create a set of six different numbers that include both positive and negative values.

Here's an example: -5, -2, -1, 1, 2, 5.

When arranged in ascending order, the median is 0 since it is the middle value.

In a game the player wins if he rolls a 4 on a number cube. If the number cube is rolled 24 times, then what is a reasonable prediction for the number of unsuccessful rolls?

Answers

Answer:  20

============================================

Explanation:

If we want to roll a 4, then theoretically we have a probability of 1/6 of that happening. This is because there's 1 face that has "4" labeled on it, out of 6 faces total.

If we roll the cube 24 times, then we expect 24*(1/6) = 24/6 = 4 instances of the "4" show up. Of course, due to the random nature of this event, it's not guaranteed. So that's why we use the "expect" there.

We expect 4 times to get successful rolls, which means we have 24-4 = 20 unsuccessful rolls. This value (20) is also an expected or predicted value, and not a guarantee.

Answers

You know each side is 9 meters long, meaning it’s a square. To find perimeter, add up all the sides aka. 9+9+9+9=36. To find the area, multiply one side by the other aka. 9x9 = 81.
Perimeter= 36
Area=81
Step-by-step
Perimeter means you add, so we will add all 4 sides together 9+9+9+9=36. Area means to multiply to find the inside of something to we will multiply 9x9=81. Hope this helped! :)
