A 28ft ladder leans against a wall so that the base of the ladder is 5ft away from the base of the wall. How far up the wall doe
valentinak56 [21]

Answer:

the top of the ladder is 27.5ft above the ground.

Step-by-step explanation:

The ladder makes an angle, θ with the ground thus forming a right angle triangle with the wall of the house.

The length of the ladder represents the hypotenuse of the right angle triangle.

The ground distance from the base of the wall to the foot of the ladder represents the adjacent side of the right angle triangle.

Therefore, to determine how high up is the top of the ladder on the wall, x, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

28² = x² + 5²

784 = x² + 25

x² = 784 - 25 = 759

x = √759 = 27.5ft

28. Construct a rectangle ABCD in which AB = 4 cm, BC = 3.5 cm. Construct a triangle whose area is equal to that of rectangle AB
Hatshy [7]

Answer:

Triangle b = 4, h = 7

Step-by-step explanation:

Rectangle area = L*W

Triangle area = (B*H)/2

Rectangle/2 = Triangle

If you want triangle to = rectangle, then rectangle*2/2

Rectangle = 4*3.5 = 14

Triangle = 4*7 = 28/2 = 14

For the function y= -1+6 cos ( 2π/7(x-5) ), what is the maximum value​
RUDIKE [14]

Answer:

5

Step-by-step explanation:

I'm assuming you want to find the maximum value of y

recall that for any cosine function y = A cos (  g(x) ), where g(x) is any arbitrary function, that A represents the amplitude of the cosine function.

By definition, the amplitude is the maximum the value which the cosine term can take.

hence for your expression:

y= -1 + 6 cos ( 2π/7(x-5) )

max value of y = -1 + (max value of cosine function)

max value of y = -1 + (amplitude of cosine function)

max value of y = -1 + 6 = 5
