The temperature in Doha, Qatar on 1 June is 40°C. Over
the next two days this temperature increases by 10%
followed by a decrease of 10%. Find the temperature in
Doha on 3 June.

Answer:

a) 4 to the 14th power

b) 12 to the 9th power

c) 5 to the 7th power

d) 7 to the 3rd power

Step-by-step explanation:

a) [tex]4^{6}[/tex] · [tex]4^{8}[/tex] equals 4 to the 14th power.

Using the Product Rule of Exponents:

[tex]a^{m} a^{n} = a^{m+n}[/tex]

You could add the exponents since they have the same base.  

b) [tex]12^{6}[/tex] · [tex]12^{3}[/tex]  equals 12 to the 9th power.

Same Product Rule applies as we did in problem a).

c) [tex]\frac{5^{10} }{5^{3} }[/tex]  equals 5 to the 7th power.

Using the Quotient Rule of Exponents:

[tex]\frac{a^{m} }{a^{n} } = a^{m - n}[/tex]

You'll have to subtract the exponents since they have the same base.

[tex]\frac{5^{10} }{5^{3} } = 5^{10 - 3} = 5^{7}[/tex]

d) [tex]\frac{7^{6} }{7^{3} }[/tex]  equals 7 to the 3rd power.

Same Quotient Rule applies as we did in problem c).

[tex]\frac{7^{6} }{7^{3} } = 7^{6 - 3} = 7^{3}[/tex]

Answer:

4.19$

Step-by-step explanation:

If 12 gallons cost 50.28$

then 1 gallon would be (50.28/12)$

which equals to 4.19$

The Teddy's jobs at home is to pump gas for his family's sedan and truck the cost of gas of one gallon is:

=> The unit rate is:

=> $4.19 per gallon

We have the following information available from the question is:

One of Teddy's jobs at home is to pump gas for his family's sedan and truck.

When he fills up the sedan with 12 gallons of gas, he notices that it costs him $50.28.

Now, According to the question:

The cost of gas of one gallon is:

Answer:

  m ≥ -√5

Step-by-step explanation:

If g(x) = f(|x|) for x∈i, then g(x) = f(x) for x∈ℝ: x ≥ 0.

f'(x) is 5th-degree, so f(x) is 6th-degree, meaning it is generally U-shaped. Since we're only concerned with x ≥ 0, we want to make sure f'(x) has no real zeros of odd multiplicity such that x > 0. The given factors of f'(x) make it have real zeros at x = -3 and x = -1.

For the last factor, (x² +2mx +5) to have no positive real zeros of odd multiplicity, we must have m ≥ 0 or the discriminant ≤ 0. The discriminant is ...

  d = b² -4ac = (2m)² -4(1)(5) = 4m² -20 . . . . . discriminant of the last factor

  d ≤ 0 . . . . . . . . . . the condition for no real zeros

  4m² -20 ≤ 0

  m² -5 ≤ 0 . . . . . . divide by 4

  m² ≤ 5 . . . . . . . . .add 5

  |m| ≤ √5 . . . . . . . take the square root

This tells us there will be a positive real zero of multiplicity 2 in f'(x) when m = -√5, and there will be no positive real zeros for -√5 < m < 0

There will be no odd-multiplicity positive real zeros in the derivative function f'(x) as long as m ≥ -√5. This means the slope of f(x) is non-negative for x ≥ 0, hence f(|x|) has its only minimum at x=0.

_____

Additional comment

The multiplicity of the zeros of f'(x) is important because the derivative will only change sign where the multiplicity is odd. When the discriminant of (x²+2mx+5) is zero, the associated positive real zero will have multiplicity 2, hence f'(x) will not change sign there.

Answer:

  vertical

Step-by-step explanation:

A rational function often tends to infinity when its denominator tends to zero. Thus the zeros of the denominator correspond to vertical asymptotes.

Step-by-step explanation:

if 2 sides are equal which means it is an Isosceles triangle

so,

→ 52 + 52 + c = 180

→ 104 + c = 180

→ c = 180 - 104

→ c = 76°

d = 52°

Answer:

popcorn 3.29$

popcorn + 15 pack juice = 27.14$

Step-by-step explanation:

15 pack juice= 27.14-3.29

15 pack juice=23.85

pack of juice=23.85/15

pack of juice=1.59$

The equation that shows the cost of each bottle of juice is 15j + 3.29 = 27.14 and the cost of each juice is $1.59

An equation is an expression that shows the relationship between two or more numbers and variables.

Let j represent the cost of each bottle of juice. The total cost before tax was $27.14, hence:

15j + 3.29 = 27.14

j = 1.59

The equation that shows the cost of each bottle of juice is 15j + 3.29 = 27.14 and the cost of each juice is $1.59

Explanation:

There are 5 choices for the first selection, 4 choices for the second, etc etc until we reach 1 for the last selection. We have the countdown {5,4,3,2,1}. We'll multiply those values together to get our answer.

5*4*3*2*1 = 120

This operation of starting with some integer, counting down and multiplying along the way, is done so very often that it's given a name which is "factorial". The shorthand notation is to use an exclamation mark. So we'd say 5! = 120

Answer:

Step-by-step explanation:

a)  Sum = - 6

Product = - 16

Factors = (-8) ; (2   {-8 + 2 = -6  ; (-8) * 2 = -16}

y = x² - 6x - 16

     = x²  + 2x - 8x - 16

     = x(x + 2) - 8(x + 2)

    = (x +2)(x -8)

b) y = 0

(x +2 )(x -8) = 0

x + 2 = 0  ;   x -  8 = 0

x = -2       ;  x = 8

(-2) ; 8 are the zeros.

area = l x 5l + 2

Step-by-step explanation:

area equals length times 5 times the length plus two

The expression for the area will be equal to x(5x + 2).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Flowerbed A has length x feet and width that is two feet more than five times its length

Lenght = x

width = 5x + 2

Area =  L x W

Area = x ( 5x + 2 )

Area = 5x² + 2x

Therefore, the expression for the area will be equal to x(5x + 2).
