Answer:

1.  y=(x+3)^2-4

2. y=(x+4)^2-3

3. y=(x-3)^2+4

4. y=(x-4)^2+3

Step-by-step explanation:

The vertex from of a quadratic function is

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

where, a is constant and (h,k) is vertex.

(1)

The vertex of the parabola is (-3,-4).

y=a(x-(-3))^2+(-4)

y=a(x+3)^2-4

The graph is passes through the point (-1,0).

0=a(-1+3)^2-4

4=4a

1=a

y=(1)(x+3)^2-4

y=(x+3)^2-4

Therefore, the required equation is y=(x+3)^2-4.

Similarly,

(2)

The vertex of the parabola is (-4,-3).

y=a(x+4)^2-3

The graph is passes through the point (-3,-2).

-2=a(-3+4)^2-3

a=1

Therefore, the required equation is y=(x+4)^2-3.

(3)

The vertex of the parabola is (3,4).

y=a(x-3)^2+4

The graph is passes through the point (2,5).

5=a(2-3)^2+4

a=1

Therefore, the required equation is y=(x-3)^2+4.

(4)

The vertex of the parabola is (4,3).

y=a(x-4)^2+3

The graph is passes through the point (3,4).

4=a(3-4)^2+3

a=1

Therefore, the required equation is y=(x-4)^2+3.

Adam uses coconut milk for the dessert. The coconut milk is in a can but he doesn’t know how much the can holds. The can is 12 c
SOVA2 [1]
Given:
Diameter = 8 cm
Height = 12 cm
Value of pi = 3

radius is 1/2 of the diameter. r = 8cm/2 = 4cm
Volume = π r² h
V = 3 * (4cm)² * 12 cm
V = 3 * 16cm² * 12 cm
V = 576cm³

Volume of the can is 576cm³. It is also the amount of milk inside the can.

The initial temperature of a cup of tea is 200ºF. The surrounding temperature is 70ºF, and the value of the constant k is 0.6.
Nezavi [6.7K]

Newton's Law of Cooling states that the change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature over time.

Therefore when expressed mathematically, this is equivalent to:

dT = - k (T – Ts) dt

dT / (T – Ts) = - k dt

Integrating:

ln [(T2– Ts) / (T1– Ts)] = - k (t2 – t1)

Before we plug in the values, let us first convert the temperatures into absolute values R (rankine) by adding 460.

R = ˚F + 460

T1 = 200 + 460 = 660 R

Ts = 70 + 460 = 530 R

ln [(T2– 530) / (660 – 530)] = - 0.6 (2 - 0)

T2 = 569.16 R

T2 = 109 ºF

Answer: After 2 hours, it will be 109 ºF
