If the area of a rectangle equals 40 square feet and it’s length is 10 feet, what is the width?

Olenka [21]

Answer:

w=4

Step-by-step explanation:

The area of a rectangle is given by

A = l*w

The area is 40 and the length is 10

40 = 10*w

Divide each side by 10

40/10 = 10w/10

4 =w

lord [1]

The function f(t) = 7 cos(pi over 4t) + 12 represents the tide in Light Sea. It has a maximum of 19 feet when time (t) is 0 and a minimum of 5 feet. The sea repeats this cycle every 8 hours

To find the height of the tide after 2 hours, we plug in 2 for t and find out f(2)

$f(t) = 7 cos(\frac{\pi}{4})t+ 12$

$f(2) = 7 cos(\frac{\pi}{4})*2+ 12$

$f(2) = 7 cos(\frac{\pi}{2})+ 12$

We know that cos (pi/2) is 0

$f(2) = 7 (0)+ 12$

So f(2)= 12

After two hours, the height of the tide is 12 feet

Write an equation of the line, in point-slope form, that passes through the two given points. points: (–16, 8), (4, –2)

Aleks04 [339]

This is the same question as from DINW 220, but I will answer.
This form of the straight line is an equation through the two points and it reads => y-y1= (y2-y1)/(x2-x1) (x-x1), point 1 (-16,8) and poin2 (4, -2) , x1= -16, y1= 8, x2= 4 and y2= -2 =>
y-8 = (-2-8)/(4-(-16)) (x-(-16)) => y-8= -10/(4+16) (x+16) =>
y-8= (-10/20) (x+16) If we simplify fraction (-10/20) we get (-1/2) =>
y-8=(-1/2) (x+16) we will multiply the both sides of the equation with number (2) we get 2y-16= ( -1) (x+16) => 2y-16= -x -16, we will add to the both sides number (+16) => 2y= -x than divide the both sides with number (2) we get y= (-1/2)x where -1/2 is coefficient of direction or (slope) and this linear function have not cut on the y axis, because it goes through a coordinate start ( 0,0) in the decartes coordinate system.

In two or more complete sentences, describe the transformation(s) that take place on the parent function f(x) = 3x to obtain the

zepelin [54]

If you mean 3(-x+1)+5:

There is a vertical stretch by a factor of 3. There is a reflection over the y axis. The graph moves left one unit and up by 5 units.

Hope this helps, and I provide an image in case it helps!
