melisa1 [442]3 years ago
7 0

Answer:

It moves horizontally 1/2 units to the left

It moves vertically 2 units up

Step-by-step explanation:

∵ y = Acos(Bx - C) + D

∵ y = 2 - 3cos(2x + 1)

∴ The phrase of shift:

∵ The horizontally shift is -C/B = - 1/2 = -1/2

∴ It moves 1/2 units to the left

∵ The vertically shift is D

∴ It moves 2 units up

10. The sum of three consecutive integers is 45. What are the three integers?
spayn [35]

Answer:

<h3>            14, 15, 16</h3>

Step-by-step explanation:

The consecutive integers iincrease by 1. So the middle integer of an odd number of consecutive integers is their mean. Three is an odd number of integers.

45:3 = 15   ← middle number

15 - 1 = 14   ← the smallest number

15 + 1 = 16  ← the largest number

You want to buy a trampoline. You found one online that has a circumference of 6.28 yards. What is the area?
gizmo_the_mogwai [7]

The area of the trampoline  is mathematically given as

a = 3.14

<h3>What is the area?</h3>

Question Parameters:

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference   is mathematically given as

C = 2*pi*r

Thererfore

6.28 = 2*3.14*r

r = (6.28)/(6.28)

r = 1

In conclusion, where radius is

a= pi*r^2

a = 3.14*1^2

a = 3.14

PLEASSEEEE HELP ASAP , WHAT IS THE SHAPE OF THE BASE AND SURFACE AREA?
zmey [24]

Answer:

Total surface area : 733

The shape of the base is a rectangle with sides 11 in. and 12 in.

Step-by-step explanation:

The shape of the base is a rectangle with sides 11 in. and 12 in.

The surface area is the sum of the areas of the 5 sides.

Area of the base = 11*12 = 132

Area of the two triangles =  (11*16)/2 = 88

Area of the back rectangle = 192

The theorem of Pitagora to find the oblique side: square root of (11*11 + 16*16)= 19.42 in.

So the area of the oblique face: 19.42* 12 = 233 (almost :) )

So total surface area: 132 + 88*2+192+233= 733 square in
