Answer:
Radius of sphere is 3 units.
Step-by-step explanation:
Volume of sphere is given by
surface area of sphere is given by
where r is the radius of the sphere.
Given that
The number of cubic units in the volume of a sphere is equal to the number of square units in the surface area of the sphere.
we equate formula of Volume of sphere and surface area of sphere
assuming r as the radius.
thus,
Thus, radius of sphere is 3 units.
<h2>Hello!</h2>
The answer is:
The correct option is the first option:
To write the equation of the line in slope-interception form we need to extract all the information that we need from the graphic.
We must remember that the slope-interception form of the lines is:
Where,
y, is the function
m, is the slope of the line
x, is the variable
b, is the y-axis intercept
We can find the slope using the following formula:
Which is for this case:
As we can see from the graphic, the line is decresing, so the sign of the slope "m" will be negative, so:
We can find the value of "b" seeing where the line intercepts the y-axis.
As we can see it intercept the y-axis at:
Then, now that we already know the value of "m" and "b", we can write the equation of the line:
So, the correct option is the first option:
Have a nice day!
Answer:
y = x + 2
Step-by-step explanation:
To find the slope:
Find two spots where the line intersects and exact point. (-8,-4)(-4,-1)
Either count up & over or do y1-y2 / x1-x2 (-4+1)/(-8+4) -3/-4 3/4
The intercept is where it crosses the y-axis, in this case 2
Write the equation like this y = mx + b where m=slope & b=intercept
y = 3/4x + 2
