temperature decreased by -3.5 degrees

Step-by-step explanation:

-14 3/4 = -14.75

-18 1/4 = -18.25

-14.75 + X = -18.25

X = -3.5 or -3 2/4

Answer:

Step-by-step explanation:

This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.

  x -2.6 ≥ 9.4

  x ≥ 12.0 . . . . . . add 2.6 to both sides

The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.

The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.

Step-by-step explanation:

Given the following:

Vocalist needed :

First day (a) = 6

For subsequent days : number doubles

Using the relation. :

Sn = a(r^n -1)/(r -1)

Where a = first term = 6

r = common ratio = r3/r2 = r4/r3

Since number doubles after each consecutive day, then ; r = 2, n = 10

Sn = 6(2^10 -1)/(2 -1)

Sn = 6(1024 - 1) / 1

Sn = 6144 - 6

Sn = 6138

The exponential function is given by y = 13000(0.85)ˣ, the amount of rats in 3 years is 7984

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y represent the population of the chicken after x year.

The initial population of 13000 rats, hence a = 13000

The rat population declining by 15% every year. b = 1 - 0.15 = 0.85

The exponential function is given by y = 13000(0.85)ˣ

In 3 years; y = 13000(0.85)³ = 7984

The exponential function is given by y = 13000(0.85)ˣ, the amount of rats in 3 years is 7984

Answer:

area = 84 cm²

Step-by-step explanation:

the quadrilateral is made up of 2 triangles ABD and BDC

area of Δ ABD = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

A = [tex]\frac{1}{2}[/tex] × BD × AE = [tex]\frac{1}{2}[/tex] × 14 × 7 = 7 × 7 = 49 cm²

area of Δ BDC = [tex]\frac{1}{2}[/tex] × BD × CF = [tex]\frac{1}{2}[/tex] × 14 × 5 = 7 × 5 = 35 cm²

area of ABCD = 49 + 35 = 84 cm²

Answer:

Algebraic "proof" that the solution is 2:

[tex]\sqrt{9-4\sqrt{5} }\:+\sqrt{5}[/tex]

[tex]=\sqrt{4-4\sqrt{5}+5 }\:+\sqrt{5}[/tex]

[tex]=\sqrt{2^2-4\sqrt{5}+(\sqrt{5})^2 }\:+\sqrt{5}[/tex]

[tex]=\sqrt{(2-\sqrt{5})^2 }\:+\sqrt{5}[/tex]

[tex]=(2-\sqrt{5})+\sqrt{5}[/tex]

[tex]=2[/tex]

However, this is not the correct mathematical solution to the problem.

The order of operations for [tex]\sqrt{(2-\sqrt{5})^2 }[/tex] dictate that the operation inside the parentheses must be carried out first.  

As [tex]2-\sqrt{5} < 0[/tex], then [tex](2-\sqrt{5})^2[/tex] will always be positive.

If  [tex](2-\sqrt{5})^2[/tex] is always positive, then [tex]\sqrt{(2-\sqrt{5})^2 }[/tex] will always be positive.

As √5 > 2 and [tex]\sqrt{(2-\sqrt{5})^2 } > 0[/tex] then [tex]\sqrt{(2-\sqrt{5})^2 }\:+\sqrt{5} > 2[/tex]

So mathematically, the actual solution to the expression is 2.47 (nearest hundredth) not 2.

The central angle (127 degrees) is the angle at point K

The measures of JL and JML are 127 and 233 degrees, respectively

From the complete question, we have:

JL = 127 degrees.

The sum of angles at a point is 360 degrees

So, we have:

JML + 127 = 360

Subtract 127 from both sides

JML = 233

Hence, the measures of JL and JML are 127 and 233 degrees, respectively

The equivalent four-term polynomial which can be created using the x method is,

[tex]x^2 +12x +4x+ 48[/tex]

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result. X-method is the method to find the factors of the polynomial equation.

The polynomial equation is given as,

[tex]x^2 +16x +48[/tex]

An x-method chart shows the product a c at the top of x and b at the bottom of x for the standard polynomial equation. The standard polynomial equation can be given as,

[tex]ax^2+bx+c[/tex]

Comparing the given equation with standard polynomial equation, we get,

[tex]a=1\\b=16\\c=48[/tex]

The x method chart is attached below for the given equation.

The terms 16 x can be divided into the two terms 12x and 4x using the X-method. Thus the equation will become,

[tex]x^2 +12x +4x+ 48[/tex]

Thus, the equivalent four-term polynomial which can be created using the x method is,

[tex]x^2 +12x +4x+ 48[/tex]

Answer:

C. x2 + 12x + 4x + 48

Answer: 5/2 liters (or 2.5 liters) of juice were in the jar to start.

The jar was filled at a rate of 5 minutes.

Step-by-step explanation: Firstly, rearrange the equation so that y = mx + b. If you move the x over, you get -2y = -3x -5. To get rid of the -2 in front of the y, divide both sides by -2. Then you get y = 3/2x + 5/2.

The amount of juice in the jar initially is b, also known as the y-intercept.

If you look at the equation, you see that 5/2 is our y-intercept which means the jar initially had 5/2 liters of juice at the start (this is the same as 2.5 liters because 5 divided by 2 is 2.5).

To find the rate at which the jar was filled, you need to solve for x. Plug in the 10 liters for the y and solve.

y = 3/2x + 5/2

10 = 3/2x + 5/2

Now, subtract 5/2 from both sides.

7.5 = 3/2x

Divided both sides by 3/2 to get x alone, which will give you the number of minutes in which the jar was filled.

5 = x

The jar was filled at a rate of 5 minutes.

Dado que la longitud, la profundidad y la altura de un cubo son iguales, podemos acortar el proceso elevando al cubo cualquiera de estas medidas. Sigamos con el ejemplo. Dado que la longitud de cualquier arista de este cubo es de 5 cm (2 pulgadas), podemos hallar el volumen multiplicando 5 x 5 x 5 (o 53) = 125.
