Answer: 2.8%

Step-by-step explanation:

Give, In a certain month a family spent $750 on food

In third month the family spent $729 on food .

i.e.  Expenditure on food in a certain month = $750

Expenditure on food in third month = $729

Decrease in monthly spending on food = (Expenditure in a certain month )- (Expenditure in third month )

= $750  -  $729

= $21

Now , the percentage decrease in the month spent on food will be :

\dfrac{\text{Decrease in monthly spending on food }}{\text{Expenditure on food in a certain month}}\times100\\\\=\dfrac{21}{750}\times100\\\\=2.8\%

Hence, the percentage decrease in the month spent on food  is 2.8%.

Are my answers correct? Precalculus!!

Answer:

Unfortunately, your answer is not right.

Step-by-step explanation:

The functions whose graphs do not have asymptotes are the power and the root.

The power function has no asymptote, its domain and rank are all the real.

To verify that the power function does not have an asymptote, let us make the following analysis:

The function y = x ^ n , when x approaches infinity, where does y tend? Of course it tends to infinity as well, therefore it has no horizontal asymptotes (and neither vertical nor oblique)

With respect to the function y= \frac{1}{x} we ​​can verify that if it has asymptote horizontal in y = 0. Since when x approaches infinity the function is closer to the value 0.

For example: 1/2 = 0.5;   1/1000 = 0.001;    1/100000 = 0.00001 and so on. As "x" grows "y" approaches zero

Also, when x approaches 0, the function approaches infinity, in other words, when x tends to 0 y tends to infinity. For example: 1 / 0.5 = 2; 1 / 0.1 = 10; 1 / 0.01 = 100 and so on. This means that the function also has an asymptote at x = 0

Match the number set or type of number with the correct category
beks73 [17]

An integer is a rational number; 1/2 is a rational ratio with a denominator of 1; 0.4545 is a rational decimal; 0.44 is a irrational decimal and 0 is a rational whole numbers.

<h3>What is the difference between a rational and a irrational number?</h3>

The category irrational number can be applied to numbers that cannot be expresses as ratios or fractions. This includes decimals that do not terminate and are not repeating such as 0.44454...

<h3>On the other hand, rational numbers will include different types of numbers such as:</h3>

Integers: This refers to numbers that are not expressed as fractions.

Rational decimals: This includes repeating decimals such as 0.4545...

Rational ratios: This includes numbers such as 1/2 or 1/4.

Rational whole numbers such as 0,1,2, etc.

Write an equation for the graph, where y depends on x.
Over [174]

Answer:

y = -3x + 6

Step-by-step explanation:

Equation of straight line is given by,

y = mx + b

m = slope of the line

b = y-intercept

From the graph attached,

m = \frac{\text{Rise}}{\text{Run}}

   = \frac{-6}{2}

   = -3

y intercept 'b' = 6

Therefore, equation of the line will be,

y = -3x + 6

20 Points! Which ordered pair is the best estimate for the solution of the system of equations?
yan [13]

Answer:

The best estimate for the solution is the ordered pair  (-6.5,-3.5)

Step-by-step explanation:

we have

y=\frac{3}{2}x+6 ------> equation A

y=\frac{1}{4}x-2 ------> equation B

we know that

using a graphing tool, the solution of the system of equations is the intersection point both graphs

The intersection point is (-6.4,-3.6)

therefore

The best estimate for the solution is the ordered pair  (-6.5,-3.5)

How do i solve this?
shusha [124]

Answer:

Step-by-step explanation:

You can use Pythagoras Theorem,

8^{2} + y^{2}  = (8\sqrt{6} )^{2} \\      y^{2}        = (8\sqrt{6} )^{2} - 8^{2} \\y^{2} = 384 - 64\\y^{2} = 320\\y  = \sqrt{320}

∴ y = 8\sqrt{5}

Hope that helps!!
