Yes

Step-by-step explanation:

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

Answer:

True.

Step-by-step explanation:

The quadratic equation [tex]y=2(x+3)^2-1[/tex], is in fact written in vertex form.

Vertex Form = [tex]y=a(x-h)^2+k[/tex]

[tex]a=amplitude[/tex]

[tex]h=horizontal shift[/tex]

[tex]k=vertical shift[/tex]

so whats the question then?

Step-by-step explanation:

Answer:

35$ becuase 5 times ten dollars for each person for lunch then yoy take that 50 and subtract it from 225 then you divide 175 which is the sum of 50 minus 225 and divided 175 by 55 and you get 35

Answer:

$4000

Step-by-step explanation:

Given that :

Volume of cube = 8000 ft³

Charge per ft² = $10

Recall, volume of a cube = a³

Where a = edge

Hence,

a³ = 8000

Take the cube root of both sides

a = 20

Hence,

Volume = 20 * 20 * 20

The Area of the floor will be :

20 * 20 = 400 ft²

If charge per ft² = $10

400 ft² = ($10 * 400) = $4000

Answer:Here

Step-by-step explanation:

Height at an instance of time is given by :

h(t) = -4( t - 2 )² + 5     .....1

Differentiating above equation with respect to t .

[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]

Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .

8( t - 2 ) = 0

t = 2

Putting value of t = 2 in given equation, we get :

h( 2 ) = -4( 2 - 2 )² + 5

h( 2 ) = 5 m

Therefore, maximum height rocket can reach is 5 m.

Answer:

1,680

Step-by-step explanation:

n!/(n-r)!

in this case n= 8 and r= 4

so 8!/(8-4)! = 1,680

The possible permutation of 8 objects taken at 4 a time will be 1680.

The linear arrangement of the set of the orders or the linear arrangements of the numbers is called the permutation.

The number of possible permutations of 8 objects taken 4 at a time will be:-

[tex]^8C_4=\dfrac{8!}{(8-4)!}[/tex]

[tex]^8C_4=\dfrac{8!}{(4)!}[/tex]

[tex]^8C_4=\dfrac{8 \times 7\times 6\times 5\times 4\times 3\times 2}{4\times 3\times 2}=1680[/tex]

Therefore the possible permutation of 8 objects taken at 4 a time will be 1680.

Answer:

18x0.20 = 3.6 18-3.6 = 14.4

anwser- $14.40

Step-by-step explanation:

18 is the original price of the shirt, and 20% is the discount. You can write the discount as 0.20 because it is the same as 20/100. To get the discount you have to multiply the original price and the discount, 18x0.20, 3.6. 3.6 is the discount price which means, it is not the final price because it only is 20% of 18. To check, multiply 3.6 by 5 becuse  100%= 1  and 5 times 0.2 equals to 100% (1). 3.6 x5 = 18. To get the final price, subtract 3.6 from 18 so the  dicount  can be added to the  final price. Hope this helps :)

Answer: The area of garden B is 234.8% of the area of garden​ A.

Step-by-step explanation:

Given: Garden A has area 25 square meters. Garden B has area 58.7 square meters.

The percent of the area of garden​ A is the area of garden B =

[tex]\dfrac{\text{area of garden B}}{\text{area of garden A}}\times100[/tex]

[tex]=\dfrac{58.7}{25}\times100\%\\\\= 58.7\times4\%\\\\= 234.8\%[/tex]

Hence, the area of garden B is 234.8% of the area of garden​ A.

Answer:

Less.

Step-by-step explanation:

The way decimals and numbers in general work, each number to the right becomes 10 times less than the one before. Therefore, adding a 0 BEFORE the numbers would make 0.058 10 times less than 0.58.

In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2π (18 cm) = 36π cm. Convert the angular speed, 36π cm/rev, to linear speed:

(36π cm/rev) • (35 rev/min) = 1260π cm/min ≈ 3958 cm/min
