What is the equation of the line that passes through the points (–2, 2) and (0, 5)?
lana66690 [7]

Answer:

The equation of line is given by

y=\frac{3}{2}x+5

Step-by-step explanation:

We have been given the points (–2, 2) and (0, 5) and we have to find the equation of the line.

Let us first find the slope of the line using the formula

m=\frac{y_2-y_1}{x_2-x_2}

On substituting the values, we get

m=\frac{5-2}{0+2}

m=\frac{3}{2}

Now, using the point slope form, the equation of line is given by

y-y_1=m(x-x_1)\\y-2=\frac{3}{2} (x+2)\\\\y-2=\frac{3}{2}x+3\\\\y=\frac{3}{2}x+5

Therefore, the equation of line is given by

y=\frac{3}{2}x+5

Find the radius of a circle with an area of 89 sqaure feet.​
Dominik [7]
I am pretty sure that to find the area of a circle, it’s pi times radius squared.
So in your situation, the formula would be p89 squared. So first, multiply 89 times 89, which equals 7921. You could leave it and say the answer is 7921 pi squared, or you could multiply 7921 by 3.14 (pi rounded), which would get you 24871.94 So the answer would either be:
1.) 7921 pi squared
2.) 24,871.94 feet squared
Hope this helps

"Conservationists have despaired over destruction of tropical rain forest by logging, clearing, and burning." These words begin
krok68 [10]

Answer:

The answer is "(0.461 , 7.206)"

Step-by-step explanation:

In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:

UnLogged:

x_1=17.500\\s_1=3.529\\n_1=12

Logged:

x_2=13.667\\ s_2=4.500\\n_2=9\\

formula of std error:

\ std \ error =\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}

                =\sqrt{\frac{3.529^2}{12}+\frac{4.500^2}{9}}\\\\=\sqrt{\frac{3.529^2\times 3+4.500^2\times 4}{36}}\\\\=1.8133

Point differential estimation =x_1-x _2

                                              = 17.500-13.667\\=3.833

For 90 percent t= 1.860 Cl & 8 df  

error of margin E = t\times \ std \ error

                             = 1.860 \times 1.8133\\= 3.373

Lower bound =mean difference -E=0.461

Upper bound = mean difference+ E=7.206

In the above 90% confidence interval were the population mean= (0.461 , 7.206)
