find the surface area! correct gets brainliest!

Answer:

5 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1 )^2 }[/tex]

with (x₁, y₁ ) = (6, 4) and (x₂, y₂ ) = (3, 8)

d = [tex]\sqrt{(3-6)^2+(8-4)^2}[/tex]

   = [tex]\sqrt{(-3)^2+4^2}[/tex]

   = [tex]\sqrt{9+16}[/tex]

    = [tex]\sqrt{25}[/tex]

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:

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

Answer: 268

Step-by-step explanation: substitute pi with 3.14, & then 4^3 as 64 in the second line. after, you multiply 3.14 x 64 you get 201 after you round. finally multiply 4 x 201 then divide your answer by 3. you get 268. (no one helped so i did)

Answer:

2x - (0.50x + 18) = profit

Step-by-step explanation:

x = number of carnations, for example if 3 carnations were sold, $6 from sales - (1.50 + 18) = profit. The 50 cents from each carnation that they bought to sell, plus 18 delviery fee. Hope this helped! Good luck!

Answer:

3.125

Step-by-step explanation:

Kate walks 5 miles in 2 hours (120 minutes)

The distance she can works in 1 hour 15 minutes can be calculated as follows

This can be calculated using proportion

d/75= 5/120

Cross multiply

d×120= 75×5

120d= 375

d= 375/120

= 3.125

This is because it is asking for a budget meaning that you have to spend less or equal to 200

Step-by-step explanation:

as c and n directly vary it can be said that

[tex]\frac{8}{13} = \frac{n}{4}[/tex]

now we just solve for n

[tex]\frac{8}{13}=\frac{n}{c} \\13n=32\\n=2.46[/tex]

#1  Multiply the two polynomials.

[tex](2x+3)(5x^2+3x+2)=(2x)(5x^2)+(2x)(3x)+(2x)(2)+(3)(5x^2)+(3)(3x)+(3)(2)\\=10x^3+6x^2+4x+15x^2+9x+6\\=10x^3+21x^2+13x+6[/tex]

#2

[tex](3y+4)(2y^2+5y-3)=(3y)(2y^2)+(3y)(5y)-(3y)(3)+(4)(2y^2)+(4)(5y)-(4)(3)\\=6y^3+15y^2-9y+8y^2+20y-12\\=6y^3+23y^2+11y-12[/tex]

Answer:

(ABOUT) 28.27433

Step-by-step explanation:

C = 2πr or dπ (because 2*r = d)

For this case:

C = dπ

C = 9π

C = 28.27433

You can round if you want to (like 28.3 or 29.27).

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,

2h+17

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