Answer:

15°C

Step-by-step explanation:

Time           Temperature

Midnight  -6°C

4 am         -8°C

8 am         -4°C

noon          7°C

3 pm          6°C

7 pm         -2°C

We are supposed to find he difference between the lowest temperature and the highest

So, Lowest temperature = -8°C

Highest temperature = 7°C

Difference between the lowest temperature and the highest = 7°C-(-8°C)

                                                                                                     =15°C

Hence the difference between the lowest temperature and the highest is 15°C

The highest is 7 degrees and lowest is -8 so subtract and you get a difference of 15 degrees

Who says V1=V2?
if we simplify we get
(2/3)pir₁³=12pir₂²
for V1 to equal V2


a.
solve for r₁ to find r₁ as a function of r₂
(2/3)pir₁³=12pir₂²
times 3/2 both sides and divide by pi
r₁³=18r₂²
cube root both sides
r₁=∛(18r₂²)

if solve for r₂
(2/3)pir₁³=12pir₂²
divide by 12pi both sides
(1/18)r₁³=r₂²
squer root both sides
√((1/18)r₁³)=r₂



double radius of pond which is r1
√((1/18)r₁³)=r₂
r₁ turns to 2r₁ to double radius
√((1/18)(2r₁)³)=r₂double
√(8(1/18)(r₁)³)=r₂double
(√8)(√((1/18)(r₁)³))=r₂double
√((1/18)r₁³)=r₂ so
(√8)(r₂)=r₂double
(2√2)(r₂)=r₂double
the radius of the tank is multipled by 2√2

Answer:

1) x = -2

Step-by-step explanation:

1) x + 7 + x + 11 = 14

 2x + 18 = 14

        2x = 14 - 18

     2x =  -4

       x = -4/2 = -2

Consider the polynomial below.
kotykmax [81]

Answer:

(-4x - 2)(-5x) + (-4x - 2)(3)  

Step-by-step explanation:

Your polynomial is

(-4x - 2)(-5x + 3)

The distributive property states that

a(b + c) = ab + ac

Let a = -4x - 2.  Then

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

Substitute the value of a.

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

You have just distributed the first binomial (-4x - 2) among the terms of the second binomial.
