calculate the coefficient b in the function f (x) = - x + b for which it holds that the graph passes through the point (-1,3)
Need if fast!

Answers

Answer:

b = 2

Step-by-step explanation:

For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line

Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value

where f(x) is same as y in this case

Thus, we have it that;

The radius is 6 and the height is 15 what is the volume in terms of pi the shape is a cone

Answers

Answer:

565.49 or if rounded to the nearest tenth, 565.5

Explanation:

The formula for finding the volume of a cone is V=1/3Bh

B = pi times the radius squared

h = height

Substitute 6 for r and 15 for h.

V= 1/3·[tex]\pi[/tex]·([tex]6^{2}[/tex])·15

Multiply.

V= 565.49 or 565.5 rounded to the nearest tenth.

Actually Welcome to the concept of Isosceles triangles.

They have two sides equal to each other, so we get as,

==> 3x + 3 = 2x + 8

==> 3x - 2x = 8-3

==> x = 5

hence the length of AC = 5 units.

Answer:

AC = 5

Step-by-step explanation:

here's your solution

=> This is a isosceles triangle

=> both sides are equal.

=> AB = CB

=> 3x + 3 = 2x + 8

=> 3x - 2x = 8 - 3

=> x = 5

so, AC = 5

Mrs perez drove at constant rate of speed she drove a total of 33.75 miles in 3/4 of hours what was the speed in miles per hour that mrs Perez traveled if this situation is represented by the equation d=rt

Answers

Answer:

Speed in miles per hour = 45 miles per hour

Step-by-step explanation:

Given:

Distance cover by Mrs Perez = 33.75 miles

Time taken by Mrs Perez = 3/4 hours = 0.75 hour

Find:

Speed in miles per hour

Computation:

Speed = Distance cover / Time taken

Speed in miles per hour = Distance cover by Mrs Perez / Time taken by Mrs Perez

Speed in miles per hour = 33.75 / 0.75

Speed in miles per hour = 45 miles per hour
