line passes through the point (0, –1) and has a positive slope. Which of these points could that line pass through? Check all th

sammy [17]

Answer:

Points passing though are (12, 3),(–2, –5) and (1, 15)

Step-by-step explanation:

For a line passing through (x₁,y₁) and (x₂,y₂) slope is given by $\frac{y_2-y_1}{x_2-x_1}$ .

Here we have one point (0, –1), we need to check slope of all the points given.

(12, 3)

$m=\frac{3-(-1))}{12-0}=\frac{1}{4}>0$

(–2, –5)

$m=\frac{-5-(-1))}{-2-0}=\frac{-4}{-2}=2>0$

(–3, 1)

$m=\frac{1-(-1))}{-3-0}=\frac{2}{-3}=-\frac{2}{3}$

(1, 15)

$m=\frac{15-(-1))}{1-0}=\frac{16}{1}=16>0$

(5, –2)

$m=\frac{-2-(-1))}{5-0}=\frac{-1}{5}=-\frac{1}{5}$

Points with positive slope are (12, 3),(–2, –5) and (1, 15)

Find the general solution of the following equation. Express the solution explicitly as a function of the independent variable.

Mashcka [7]

Answer:

Therefore the general solution is

$2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Step-by-step explanation:

Integration Rule:

$\int x^n dx= \frac{x^{n+1}}{n+1}+c$
$\int \frac1x dx= ln(x) +c$

Given differential equation is

$x^2 \frac{dw}{dx}= \sqrt{w}(2x+5)$

$\Rightarrow x^2 dw= \sqrt{w} (2x+5) dx$ [ multiplying dx both sides]

$\Rightarrow \frac{dw}{\sqrt w}= \frac{(2x+5)}{x^2} dx$ [ dividing $x^2\sqrt w$ both sides]

Integrating both sides

$\int \frac{dw}{\sqrt w}=\int \frac{(2x+5)}{x^2} dx$

$\Rightarrow \int w^{-\frac12} dw=\int (\frac{2x}{x^2}+\frac{5}{x^2} )dx$

$\Rightarrow \int w^{-\frac12} dw=\int \frac{2}{x}dx +\int\frac{5}{x^2} dx$

$\Rightarrow \frac{w^{-\frac12+1}}{-\frac12+1} =2ln x+5 \frac{x^{-2+1}}{-2+1}+c$ [ c is arbitrary constant]

$\Rightarrow 2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Therefore the general solution is

$2 \sqrt w = 2 ln(x) - 5 \frac1x +c$

Using the information given name each of the following figure

Sedbober [7]

Answer:

I think that's either a Rhombus or a Square.

I think it's more of a Rhombus.

Step-by-step explanation:

If all the sides are equal then its either a Rhombus or a Square. Then look if all the angles are equal and are right angles, Yes? then it's a Square. If only the angles opposite from each other are equal, then it's a Rhombus.

G(x) = 4x2 – 3x + 7<br> Find g(3)

VARVARA [1.3K]

Answer:

g(3)=34

Step-by-step explanation:

Just plug in 3 for x:

4(3)^2-3(3)+7

4(9)-9+7

36-9+7

27+7

So g(3)=34
