Answer:

The equation of line that passes through point (2,-1) and has a slope of -3 is \mathbf{y=-3x+5}

Option A is correct.

Step-by-step explanation:

We need to write equation of line that passes through point (2,-1) and has a slope of -3

The equation is written in slope-intercept form: y=mx+b where m is slope and b is y-intercept.

We are given slope: m = -3

We need to find y-intercept (b)

Using the point (2,-1) and slope m=-3, we can find y-intercept

y=mx+b\\-1=-3(2)+b\\-1=-6+b\\b=-1+6\\b=5

So, we get y-intercept b = 5

Now, the required equation having slope m =-3 and y-intercept b = 5 will be:

y=mx+b\\y=-3x+5

So, the equation of line that passes through point (2,-1) and has a slope of -3 is \mathbf{y=-3x+5}

Option A is correct.

oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters. determine the density of oak in grams per cubic cen
bogdanovich [222]

Answer:

The density of oak is <u>0.695</u> grams per cubic centimeter.

Step-by-step explanation:

Given:

Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.

Now, to find the density of oak in grams per cubic centimeter.

Mass (m) = 2.85 kilograms.

So, using conversion factor we convert into grams:

2.85\times 1000=2850\ grams.

Volume (v) = 4100 cubic centimeters.

Now, to get the density by using formula:

Density=\frac{mass}{volume} \\Density=\frac{m}{v}

Density=\frac{2850}{4100}

Density=0.695\ grams\ per\ cubic\ centimeter.

Therefore, the density of oak is 0.695 in grams per cubic centimeter.

What is the sum of the geometric series 2^0 + 2^1 + 2^2 + 2^3 + 2^3 + 2^4 + … + 2^9?
mars1129 [50]
The nth term is
an=a1(r)^(n-1)
an=1(2)^(n-1)
a1=1
r=2

the sum of a geometric seequence is
S_{n}=\frac{a_{1}(1-r^{n})}{1-r}
a1=1
r=2
we want to find S_{10} (since we minus 1, the highest exponet is 9 so add 1 to make it correct)

S_{10}=\frac{1(1-2^{10})}{1-2}
S_{10}=\frac{(1-1024}{-1}
S_{10}=\frac{(-1023}{-1}
S_{10}=1023
