Answer:

d = 3.46 units

Step-by-step explanation:

The diagram is a rectangular prism.

volume of a rectangular prism = Length × width × height

height = 5.2 units

volume = 99 units³

length = 5.5 units

width = d

Now we need to find the width which is d

volume = L × w × h

99= 5.5 × d × 5.2

99 = 28.6d

then u divide both sides by 28.6

d = 99/28.6

d = 3.4615384615

d = 3.46 units

Write the equation of a line in the slope-intercept form that contains the points A (1, 2) and B (2, 4).

aleksklad [387]

Answer: Choice A) y = 2x

slope = 2, y intercept = 0

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

Explanation:

We can see this by noting that each y coordinate is simply doubled that of the x coordinate.

x = 1 doubles to y = 2
x = 2 doubles to y = 4

So in general, x doubles to 2x to get the y coordinate. Therefore, y = 2x.

----------

Alternative method:

A more thorough step by step process would have us first finding the slope

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

m = (4 - 2)/(2 - 1)

m = 2/1

m = 2 is the slope

Use this slope value along with one of the points to find b. I'll use the point (x,y) = (1,2)

So,

y = mx+b

2 = 2*1+b

2 = 2+b

2-2 = b

0 = b

b = 0 is the y intercept

We go from y = mx+b to y = 2x+0, which simplifies to y = 2x

Hey there!

a.) 1 inch

beginning = 2; end = 3; difference of 1

b.) December, because the length was, let's say, 2, then it went down 1 (so we're at 1), then went up 3 (4), then went down

c.) in December

Hope it helps, have a great day!

An object is launched from a platform.

VikaD [51]

Answer:

45 meters

Step-by-step explanation:

If x represents the seconds after the launch, then the time of launch is when x=0 so you just need to solve for h(0)

h(0) = -5(1)(-9)

h(0) = 45

"You are dating Moon rocks based on their proportions of uranium-238 (half-life of about 4.5 billion years) and its ultimate dec

Olenka [21]

Step-by-step explanation:

Initial mass of the isotope = x

Time taken by the sample to decay its mass by 41% = t

Formula used :

$N=N_o\times e^{-\lambda t}\\\\\lambda =\frac{0.693}{t_{\frac{1}{2}}}$

where,

$N_o$ = initial mass of isotope = x

N = mass of the parent isotope left after the time, (t) = 59% of x = 0.59x

$t_{\frac{1}{2}}$ = half life of the isotope = 4.5 billion years

$\lambda$ = rate constant

Now put all the given values in this formula, we get

$0.59x=x\times e^{-(\frac{0.693}{\text{4.5 billion years}})\times t}$

t = 3.4 billion years

The age a rock is 3.4 billion years.

Initial mass of the isotope = x

Time taken by the sample to decay its mass by 35%= t

Formula used :

$N=N_o\times e^{-\lambda t}\\\\\lambda =\frac{0.693}{t_{\frac{1}{2}}}$

where,

$N_o$ = initial mass of isotope = x

N = mass of the parent isotope left after the time, (t) = 65% of x = 0.65x

$t_{\frac{1}{2}}$ = half life of the isotope = 4.5 billion years

$\lambda$ = rate constant

Now put all the given values in this formula, we get

$0.65x=x\times e^{-(\frac{0.693}{\text{4.5 billion years}})\times t}$

t = 2.8 billion years

The age a rock is 2.8 billion years.
