MARKING BRAINIEST Can you help me with this math problem please ?

Answer:

Step-by-step explanation:

a) x² - 10x + 25 = 0

(x-5)²=0

x-5=0

x=5

b) x² - 4x - 5 = 0

⇒ ( x 2 − 4 x + 4 ) − 5 − 4 = 0

⇒ ( x 2 − 4 x + 4 ) − 9 = 0

( x − 2 ) 2 − 9 = 0 ⇒

( x − 2 ) 2 = 9 ⇒

( x − 2 ) = ± √ 9 (don't forget the ± !) ⇒

x= − 1   x = 5

The required expression is 2h+17 where h is the height of Chrissy.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is a statement, 17 more than twice Chrissy's height, we are asked to convert this statement into an expression,

Let Chrissy's height be h,

Then,

Answer:

[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]2\cos^2(x)=\sin(x)+1[/tex]

And we want to find all solutions for x.

First, we should put the equation into terms of only one trigonometric ratio.

Since we are given cos²(x), we can turn this into sine. Recall the Pythagorean Identity which states:

[tex]\sin^2(x)+\cos^2(x)=1[/tex]

Therefore:

[tex]\cos^2(x)=1-\sin^2(x)[/tex]

By substitution:

[tex]2(1-\sin^2(x))=\sin(x)+1[/tex]

Distribute:

[tex]2-2\sin^2(x)=\sin(x)+1[/tex]

Isolate the equation:

[tex]2\sin^2(x)+\sin(x)-1=0[/tex]

We can factor:

[tex](2\sin(x)-1)(\sin(x)+1)=0[/tex]

Zero Product Property:

[tex]2\sin(x)-1=0\text{ or } \sin(x)+1=0[/tex]

Solve for each case:

[tex]\displaystyle \sin(x)=\frac{1}{2}\text{ or } \sin(x)=-1[/tex]

We can use the unit circle.

sin(x) = 1/2 for every π/6 and 5π/6. So, it will continue every 2π.

sin(x) = -1 every 3π/2. And this will also continue every 2π.

Hence, our solutions are:

[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]

Note:

If you only need the solutions within the interval [0, 2π), then it is:

[tex]\displaystyle x=\left\{\frac{\pi}{6}, \frac{5\pi}{6}, \frac{3\pi}{2}\right\}[/tex]

Answer:

[tex]92[/tex]

Step-by-step explanation:

[tex]2 {a}^{2} + 5 {b}^{2} \\ 2 \times {( - 6)}^{2} + 5 \times {2}^{2} \\ 2 \times 36 + 5 \times 4 \\ 72 + 20 \\ = 92[/tex]

Answer:

403 miles

Step-by-step explanation:

500 mph is 500 miles per hour

30 minuites is half an hour, so that is 250 miles west

60 degrees west, 600 miles away

so it is a triagle of 30 60 and 90.

600 is the hypotenuse of the 30 60 90 triangle

we need to find the height of the 30 60 90 triangle

using the special rule, the height is 300

the length of the 30 60 90 triangle is 300rt3

so 300rt3 - 250  is the length of another triangle.

height is still 300

hypotenuse is the distance of the actual area minus the plane's current position

(300^2 + (300rt3-250)^2)^1/2 is about 403.351433

A. way to pay in advance for using a car for a given time period

Step-by-step explanation:

I think so..

Answer:

C) a way to borrow money from a band or financial institution to pay for a car

Answer: D / none are true

Since it's proportional (it's a straight line), B and C are automatically wrong. A would seem true at first glance, BUT if you look closely at the graph, the slope of the graph is actually 2x.

Look at the beginning of the line. It starts at 18 (x = 0/y intercept) and at x = 1, you can see that y is at 16. The y value goes down by 2 every time x increases by 1. This means that the equation of the graph is -2x + 18 = y.

The graph is proportional and has an equation of y = -2x + 18. This means that A, B and C are incorrect.

Answer:

Step-by-step explanation:

It is a straight line also known as proportional. The first impression, A appears to be accurate, but closer inspection reveals that the graph's slope is actually 2x. 18 (x = 0/y intercept) and ends at x = 1, where little y is at 16. Any time x expands by one, the y value falls by two. This says that the graph's equation is -2x + 18 = y.

Answer:

The number of large size candles sells are 12 and the number of small size candles are 5 .

Step-by-step explanation:

As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y.             Equation becomes

x + y = 17

3x + 2y = 46

Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .

3x - 3x + 2y - 3y = 46 - 51

-y = - 5

y = 5

Put in the equation x + y = 17 .

x + 5 = 17

x = 17 - 5

x = 12

Therefore the number of large size candles sells are 12 and the number of small size candles are 5

Answer:

Step-by-step explanation:

As you can see from the attached picture below, the only figure that is equal to 5 whole units would be the final triangle. That is because it has 2 whole units in the middle, two half units in the top which equal 1 whole unit. And 2 units in each side corner which when combined would equal 2 whole units making it a total of 5. The rest of the shapes either hold more than 5 or less than 5 units. In the picture below, the top 3 shapes hold more than 5 units while the bottom two triangles hold less than 5.

Answer:

52/6 = 8 and 2/3

Step-by-step explanation:

52 divided by 6 is 8 and 2/3

6 multiplied by 8 is 48

52-48 is 4

so 52/6 is 8 remainder 4

or you can divide 4 by 6

4/6 = 2/3

so it can also be 8 and 2/3

52 divided by 6 as a fraction in its simplest form is 8 2/3.

To express 52 divided by 6 as a fraction, you simply write it as:

52 / 6

To simplify the fraction, find the greatest common divisor (GCD) of the numerator (52) and the denominator (6), and then divide both the numerator and denominator by the GCD.

The GCD of 52 and 6 is 2.

Divide both the numerator and denominator by 2:

(52 / 2) / (6 / 2)

This simplifies to:

26 / 3

now, we have,

Divide 26 by 3:

26 ÷ 3 = 8 with a remainder of 2

The whole number part is 8, and the remainder (2) becomes the new numerator.

The denominator remains the same.

So, 26/3 as a simplified mixed number is: 8 2/3

So, 52 divided by 6 as a fraction in its simplest form is 8 2/3.

ANSWER:

Caso estadístico: Altura de las mujeres de la poblacion indigena Sikuani.

Step-by-step explanation:

Población: Mujeres de la comunidad sikuani

Muestra: se toma una muestra de 20 datos para calcular la altura ,este dato se toma de la población total  de 165 mujeres.

M: ( 1.30, 1.20, 1.50, 1.52, 1.60, 1.37, 1.28, 1.55,1.46, 1.26, 1.57, 1.58, 1.54, 1.38, 1.56, 1.23, 1.59, 1.62, 1.48, 1.40)

Variable: Altura

Recorrido de la  variable: El recorrido de la variable es la diferencia entre el valor máximo de la muestra y el valor mínimo.

Altura máxima: 1.62 m.

Altura mínima : 1.20

Como ya tenemos el valor máximo y el valor mínimo ,podemos hallar el recorrido de la variable.

                               R=( 1.62m -1.20m)

                                        R= 0.42

Answer:

864

Step-by-step explanation:

∵X-Y=5    and.  

∵X+Y=59   add the two equations

∴2X=64

∴X=32 (substitute in any equation)

∴32 - Y=5

∴Y = 27

∴ So . X×Y=32 × 27=864

Answer:

x=32, y=27

Step-by-step explanation:

32-27=5

32+27=59

32>27

32x27=864

Answer:  100%

97:97*100 =

(97*100):97 =

9700:97 = 100

Now we have: 97 is what percent of 97 = 100

Question: 97 is what percent of 97?

Percentage solution with steps:

Step 1: We make the assumption that 97 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=97$.

Step 4: In the same vein, $x\%=97$.

Step 5: This gives us a pair of simple equations:

$100\%=97(1)$.

$x\%=97(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{97}{97}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{97}{97}$

$\Rightarrow x=100\%$

Therefore, $97$ is $100\%$ of $97$.
