Answer:

it's not

Step-by-step explanation:

if you simplify by making the denominators the same (multiplying 9/12 by 6/6 and 4/6 by 12/12), you'll arrive at 54/72 and 48/78. 54 isn't equal to 48

Answer:

C. 439.6 in.²

Step-by-step explanation:

The container is a cylinder.

Since the two circular bases won't be covered, therefore:

The least construction paper needed to cover the remaining surface = curved surface area of the cylinder

= 2πrh

r = 5 in.

h = 14 in.

Plug in the values

Curved surface area = 2×π×5×14 = 439.6 in.²

Answer:

If 0 is included in the natural numbers: 0,1,2,3

If 0 is not included in the natural numbers: 1,2,3

Step-by-step explanation:

Let n denote the natural number.

Its opposite is -n

The sum of its opposite and 8 is

-n+8

This is greater than the natural number

n<-n+8

Solve for n

2n<8

n<4

The numbers are numbers that are less than 4

If a natural number is less than the sum of its opposite and 8, this is expressed as:

n < -n + 8

n+ n < 8

2n < 8

n < 8/2

n < 4

Hence all the numbers are numbers that are less than 4

Answer: $45,000= Interest

Total= 45,000+ P. P=25000

=70000

Step-by-step explanation:

The total amount of money $53,973 is needed to pay it back in 10 years.

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex]) ^{nt}[/tex] - P

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

The given principal amount is  $25,000.

And an interest of 8.0% compounded annually.

And time period is 10 years and n = 1.

x = 25000 ( 1 + 8/10 )¹⁰ - 2500

x = $53973.12

x = $53,973

Therefore, the total amount of money $53,973 is needed to pay it back in 10 years.

Answer:

8 up, 6 left

Step-by-step explanation:

Locate any point from triangle A and go up 8 steps to get on the same level as triangle A'. Then, move to the left 6 steps.

The graph translated 6 unit left and 8 unit upward.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given, A figure "A" that translated at different position in cartesian plane.

Since,  A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but doesn't change its orientation. It also doesn't change its size or shape.

Thus, we can observe only one point on the figure and calculate the movement of the figure.

Lets focus on the left bottom corner of the figure.

It moves from the coordinates (1, -5) to the coordinates ( -5, 3)

Since Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis

So, we can say it translated to the lefty by 6 unit.

Same it goes with vertical translation.

Therefore, The graph translated 6 unit left and 8 unit upward.

Answer:

vertex is (-1,-1)

Step-by-step explanation:

2 ways

1. get into vertex form y=a(x-h)^2+k

2. use math hacks

1.

vertex is (h,k) in y=a(x-h)^2+k

complete square

y=(2x^2+4x)+1

y=2(x^2+2x)+1

y=2(x^2+2x+1-1)+1

y=2((x+1)^2-1)+1

y=2(x+1)^2-2+1

y=2(x+1)^2-1

y=2(x-(-1))^2+(-1)

vertex is (-1,-1)

2.hack way

in form y=ax^2+bx+c

x value of vvertex is -b/2a

given

y=2x^2+4x+1

b=4, a=2

xvaluevertex=-4/(2*2)

xvaluevertex=-4/4=-1

sub back to find y value

y=2(-1)^2+4(-1)+1

y=2(1)-4+1

y=2-4+1

y=-1

y value is -1

Answer:

(-1,-1)

Step-by-step explanation:

To find the x coordinate, we use the formular x = -b/2a where b=4 and a = 2 from the given function.

hence x = -(4)/2(2) = -1

then to get the y coordinate we substitute the value of x into the given function, so y = 2(-1)^2+4(-1)+1 = -1

therefore, the vertex is (-1,-1)

x=-4

Step-by-step explanation:

X would be -4 because if you distribute 2 to (-3x-4) it would give you (-6x-8) and then collecting like terms you would get (x-8=-12)  then you would add 8 to -12 whih would equal -4.

Answer:

60°

Step-by-step explanation:

the relationship between angle RST and its arc TR is:

2m∠(RST)=m(arcTR);

using this formula m∠(RST)=0.5*m(arcTR);

m∠(RST)=60°

Answer:

<S = 60

Step-by-step explanation:

The arc TR and the central angle (T to the center then to R ) are equal.

So the Central angle is 120o

S anywhere on the minor arc is 1/2 the central angle.

<S = 1/2 120

<S = 60

1. m<C = 48°.

2. <X = <Y.

<ABD = <CDB = 62°

<BDA = <DBC = 70°

<DBC + <BCD + <CDB = 180°

70° + <BCD + 62° = 180°

132° + <BCD = 180°

<BCD = 180° - 132°

<BCD = 48°

m<C = 48°

The triangle is a right triangle. If ZX = ZY then <X = <Y
