Can you help me figure out if my this answer is correct...<br> 3(4x+ 5y +6)= 12×+15y+18

svetlana [45]

Answer: Yes, well done.

Step-by-step explanation:

$3(4x+5y+6)=12x+15y+18\\(3*4x)+(3*5y)+(3*6)=12x+15y+18\\12x+15y+18=12x+15y+18$

Identify the type of function that models the situation below: The cost of mailing a letter is $0.37 for the first ounce and $0.

Gwar [14]

Answer:

The correct option is;

Step function

Step-by-step explanation:

The given information are;

The cost of mailing a letter for the first ounce= $0.37

The cost for each additional ounce = $0.23

Therefore, the cost of mailing a letter can be found from the relation;

y = (N-1) × $0.23 + $0.37

The step function can be represented as follows;

f(x) = a[b(x - h)] + k

Where;

(h. k) = The starting points

a = The vertical step separation

b = The horizontal step separation

Therefore, in the question, we have;

a = $0.23

b = 1

h = 1

k = $0.37

Which gives;

f(x) = $0.23 × [1(x - 1)] + $0.37 = $0.23 × (x - 1) + $0.37

f(x) = $0.23 × (x - 1) + $0.37 which is similar to y = (N-1) × $0.23 + $0.37

Therefore the function that models the situation is step function.

True or false <br><br> Any three points lie on a distinct line.

allsm [11]

Answer:

False

Step-by-step explanation:

A line is defined by and consists of at least two points, therefore, an extra point in the same plane can be located such that when joined to one of the previous two points to form another distinct line

However, three points can only lie on one distinct plane as the location of the third point together with the two colinear point form either three colinear points or a triangle which is a planar two dimensional polygon.

(Answer with steps please)

77julia77 [94]

Answer:

Step-by-step explanation:

a). Total surface area of cylinder is defined by sum of curved surface area and surface area of the top and bottom.

Total surface area = 2πrh + 2πr²

Skateboarders use a half pipe structure which are not closed at the ends.

Therefore, curved surface of the half pipe = $\frac{2\pi rh}{2}$

= πrh

b). If r = 2.5 m and h = 9 m,

Curved surface area of the half pipe = π(2.5)(9)

= 70.69 m²

≈ 71 m²
