strojnjashka [21]3 years ago
7 0

Answer:

28.3 cm^2

Step-by-step explanation:

We know the radius is 3 cm

To find the area we use

A = pi r^2

pi = 3.14 and r =3

A =   (3.14) * (3)^2

    3.14 *9

   28.26 cm^2

To the nearest tenth

28.3 cm^2

Write the equation of the line passing through points ( -2,-5) and (1,1)
Dennis_Churaev [7]

Answer:

The equation of the line is:

y=2x-1

Step-by-step explanation:

Given the points

  • (-2, -5)
  • (1, 1)

Finding the slope between the points

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-2,\:-5\right),\:\left(x_2,\:y_2\right)=\left(1,\:1\right)

m=\frac{1-\left(-5\right)}{1-\left(-2\right)}

m=2

We know the slope-intercept form of the line equation

y=mx+b

where m is the slope and b is the slope-intercept form

substituting the value m=2 and the point (-2, -5) to find the b-intercept

y=mx+b

-5 = 2(-2) + b

b = -5+4

b = -1

Now, substituting m=2 and b=-1 in the slope-intercept form to get the equation of a line

y=mx+b

y=2x+(-1)

y=2x-1

Thus, the equation of the line is:

y=2x-1

Select all the intervals where f is decreasing
sammy [17]

One Answer: Choice C) 0 < x < 1

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

Explanation:

Let's go through the answer choices one at a time.

  • Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
  • Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
  • In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
  • Choice D is false because choice C was shown to be true.
