A deep-sea diver must descend and ascend in short steps to equalize pressure on his body. If
the diver rises toward the surface too fast, he may suffer from a physical condition called “the bends.”
Suppose the diver started at 100 feet below the surface and rose in five steps of 15 feet each. Use an integer
to describe his new position in relation to the water surface.

Answers

Answer:

1) y=-10x+50 (it's the only negative slope / going down option and it starts at x=0 y=50)

just substitute the x with a 9

y=-10*9 +50

y= -40

2) 0.5x +5 (only positive slop and starting point at x=0 is correctly 5)

we do need to substitute y this time, with 30 obviously

30 = 0.5x +5 |-5

25 = 0.5x | *2

50 = x

3) y=-2x +50 reasoning as before

substitute x with 4

y =-2*4 +50

y = -8 +50

y = 42

If a line falls on the points (6,22) and (4,21), what is its slope? Enter your answer as a fraction in lowest terms. Use a slash mark (/) as the fraction bar​

Answers

Answer:

1/2

Step-by-step explanation:

Since we have two points, we can use the slope formula

m = (y2-y1)/(x2-x1)

    = (22-21)/(6-4)

    = 1/2

Answer:

slope , m = 1/2

Step-by-step explanation:

We have two points which are ( 6,22) and (4,21).

To find slope , using slope formula

m = ( y² - y¹ ) / ( x ² - x ¹)

Where,

m, is the slope ( y² - y¹ ) = ( 22- 21 ) ( x ² - x ¹) = ( 6 - 4 )

Substitute the values into the formula

m = ( 22 - 21 ) / ( 6 - 4 )

m = 1 / 2

Answer:

x = 48; y = 13

Step-by-step explanation:

20/5 = 52/y

4 = 52/y

4y = 52

y = 13

20/5 = x/12

4 = x/12

x = 4 * 12

x = 48

Answer:

x = 48, y = 13

Step-by-step explanation:

Since they have a pair of verticle angles, this means the triangles are similar. You find a common side (the length 5 and length 20) and you know the ratio, (divide 20 by 5) aka. the larger triangle is 4 times larger than the smaller one. That means the side lengths are also 1/4 scale. So the bigger triangle = 12(length of side)*4(ratio). Also since y is on the smaller triangle, you scale it down by 1/4, so 52 (the side length) / 4 (ratio) is 13. So y = 13, x =48

2/3 (x − 7) = −2

Answers

The right Answer is:

x = 4

Answer:

x=4

Step-by-step explanation:

2/3 (x − 7) = −2

Multiply each side by 3/2

3/2 *2/3 (x − 7) = −2*3/2

x-7 = -3

Add 7 to each side

x-7+7 = -3+7

x=4

Answers

Answer: -9/2

Step-by-step explanation:

Answer:

x = -9/2

Step-by-step explanation:

Use the law of exponents

(a^p)^q = a^(pq)

here on the left-hand-side

a=3

p=3

q=2x+6

so

(a^p)^q = (3^3)^(2x+6) = 3^(3(2x+6)) = 3^(6x+18)

The right-hand-side = 3^(2x)

Equate exponents of both sides

6x+18 = 2x

6x-2x = -18

4x = -18

x = -9/2

2. The exterior angle theorem means that the 2 angles within a triangle that is on the opposite side of the angle outside the triangle could be added to find the angle that is outside of the triangle.

3. 56 and 81 are on the opposite side of the "x" outside the triangle which means that they could be added together which equals 137 degrees.

First see the whole number. write the number with biggest whole number.

6.21

2) Then three numbers have 2 . So, now compare the tenth place.

Two numbers have same place value 2.62 and 2.612.

Compare the hundredth place value in these two numbers.

So, 2.62

3) 2.612

4) 2.061
