Which Of The Following Are Solutions To The Equation Below?Check All That Apply4x- 12x + 9 = 5

Answers

Answer 1

Answer:

A & B

Step-by-step explanation:

4x²- 12x + 9 = 5

4x²- 12x + 4 = 0

devided by 4

x²-3x+1=0

x = (3 ± √9-4)/2 = (3±√5)/2

x = (√5+3)/2 or x= (-√5+3)/2

If the hypotenyse of an isosceles triangle is 8 inches, is there enough information to find the length of the legs? If yes, find the length of the legs. Round to the nearest tenth if necessary.

Answers

Answer: 5..6 in.

Step-by-step explanation:

Given

Hypotenuse of isosceles triangle is 8 inches

In isosceles triangle two sides are equal

Suppose the other side is x

Using Pythagoras we can write

[tex]\Rightarrow x^2+x^2=8^2\\\Rightarrow 2x^2=64\\\Rightarrow x^2=32\\\Rightarrow x=4\sqrt{2}\approx 5.6\ in.[/tex]

Therefore, the lengths of the legs is 5.6 inches

Laura comprou 870 gramas de carne moida e vai dividir ingualmente em 3 pacotes. Quantas gramas terão em cada pacote?

Answers

Answer:

290 gramas

Step-by-step explanation:

Podemos interpretar a questão acima matematicamente como:

3 pacotes = 870 gramas

1 pacote = x

Multiplicação cruzada

3x = 1 × 870 gramas

Divida os dois lados por 3

3x / 3 = 1 × 870 gramas / 3

x = 290 gramas

Portanto, cada pacote conteria 290 gramas de carne moída

How do I find the answer

Answers

It’s a right angle so it’s 90 degrees :)

Answer:

x = 95 degrees

Step-by-step explanation:

First find the missing angle next to 142 (we will call it y)

y +142 = 180

subtract 142 from both sides

y = 38 degrees

then we know a triangle must have 180 degrees

so

47+38+x = 180

subtract 47 and 38 from 180

x = 95

hope this helps and makes sense :)

Use Desmos graphing calculator

Answer:

x = -2y^2

Explanation Part 1:

It's not vertical, and thus it's not a standard (y = ax^2 + b) parabola.

This must mean it's either x = 2y^2 or x = -2y^2

Explanation Part 2:

You can test values into either one to check if it works

Take (-2, 1) for example, doesn't have to be a precise coordinate pair:

First Equation

x = 2y^2

-2 = 2(1)^2

-2 = 2(1)

-2 = 2

DOESN'T WORK!

Second Equation

x = -2y^2

-2 = -2(-1)^2

-2 = -2(1)

-2 = -2

IT WORKS!

The Asian elephant is an endangered species with a current population of 45,000. This species is said to be experinceing a decline of 4.5% per year. After how many years should we expect the Asian elephant poputation ot be approximately 35,746?

Answers

Answer:

5 years

Step-by-step explanation:

Given that

The current population is 45,000

The rate of interest in declining would be 4.5% per year

The expected population is 35,746

We need to find out the no of years

Since the rate of interest decrease by 4.5% per year so after decreasing it the percentage would be 0.955

Now

Year 1 = 45,000 × 0.955 = 42,975

Year 2 = 42,975 × 0.955 =  41,041.125

Year 3 = 41,041.125 × 0.955 = 39,194.27

Year 4 = 39,194.27 × 0.955 = 37,430.53

Year 5 = 37,430.53 × 0.955 = 35,746.16

Hence, the no of years would be 5

If (-10,8) is a point on the terminal side f a angle 0 in standard position what is the value of tan0?

Answers

Answer:

The value of the tangent is [tex]-\frac{4}{5}[/tex].

Step-by-step explanation:

Let be [tex]A(x,y) = (-10, 8)[/tex] on the terminal side of an angle in standard position and let be [tex]O(x,y)[/tex] the origin of the angle and the origin of the Cartesian plane. By definition of tangent, we make use of the following expression:

[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex] (1)

Where:

[tex]x_{A}, x_{O}[/tex] - x-Coordinates of point A and point O.

[tex]y_{A}, y_{O}[/tex] - y-Coordinates of point A and point O.

If we know that [tex]x_{A} = -10, x_{O} = 0[/tex], [tex]y_{A} = 8[/tex] and [tex]y_{O} = 0[/tex], then the value of the tangent is:

[tex]\tan \theta = \frac{y_{A}-y_{O}}{x_{A}-x_{O}}[/tex]

[tex]\tan \theta = \frac{8-0}{-10-0}[/tex]

[tex]\tan \theta = -\frac{4}{5}[/tex]
