Answer:

y = -1x/2 + 1

Step-by-step explanation:

y = mx + b

Find the slope with the slope formula and two different points:

(2,0) and (0,1)

m = (1 - 0)/(0-2) = -1/2

Find the y-intercept according to the graph:

At x = 0, y = 1 so b = 1.

y = -1x/2 + 1

Find the coordinate of the midpoint of the segment with the given endpoints -7 and 8

Pachacha [2.7K]

Answer:

The coordinate of the midpoint is 1/2

Step-by-step explanation:

Midpoint

The midpoint of a segment defined in a one-dimension system is

$\displaystyle \bar x=\frac{x_1+x_2}{2}$

Where x1 and x2 are the coordinates of the points.

The given segment has endpoints x1=-7 and x2=8, thus:

$\displaystyle \bar x=\frac{-7+8}{2}$

$\displaystyle \bar x=\frac{1}{2}$

The coordinate of the midpoint is 1/2

What does volume measure?

Vinil7 [7]

Answer: d - the amount of space occupied by an object (its capacity)

Explanation:

[a] The total distance around a figure is the perimeter, this does not answer our question.

[b] The average of the sum of all items is the mean, this does not answer our question.

[c] The exposed surface of a solid shape is the object's surface area, this does not answer our question

[d] The amount of space occupied by an object is the object's volume, so this does answer our question.

PLEASE HELP

Anit [1.1K]

Answer:

$A\approx2.255 \text{ grams}$

Step-by-step explanation:

We will use the standard formula for half-life:

$\displaystyle A=A_0(a)^\frac{t}{d}$

Where A₀ is the initial amount, a is the half-life, d is the time for one half-life, and t is the number of days.

So, we will substitute 1/2 for a and 24.3 for d. This yields:

$\displaystyle A=A_0(\frac{1}{2})^\frac{t}{24.3}$

We have a 3 gram sample. Therefore, our initial amount A₀ is 3:

$\displaystyle A=(3)(\frac{1}{2})^\frac{t}{24.3}$

And we want to find the remaining sample after 10 days. So, t=10. Substitute:

$\displaystyle A=(3)(\frac{1}{2})^\frac{10}{24.3}$

Use a calculator. So:

$A\approx2.255 \text{ grams}$

Therefore, for a 3 gram sample of Phosphorous-32 with a half-life of 24.3 days, after 10 days, there will be approximately 2.255 grams remaining.
