Answers

Answer 1

Answer:

x=139°

Step-by-step explanation:

7 sides

180(7-2)=900°

900-(118+129+129+109+137)=278

278/2=139°

Answer:

Use Pythagorean Theorem to find the distance between the two points

[tex]x^{2} +y^{2} =r^{2}[/tex] where r is the distance between the two points

Δx = 6-4 = 2

Δy = 3-(-1) = 4

2²+4²=r²

4+16=r²

20=r²

√20=r

r=4.47

r=4.5

4.5÷2=2.25 (halfway)

∴The distance between the cafeteria and the bathrooms is 2.25 units

Hopefully you understand how I got this answer.

Answer:

(5,1)

Step-by-step explanation:

So for this one we just find the length between the x values and the length between the y values and divide by 2 to find how far it will be ( if that makes sense.)

the distance between the two x values is 2 and the distance between the two y values is 4

2/2 = 1 and 4/2 = 2

then we subtract 1 from the x value and 2 from the y value ( using the coordinates of the cafeteria btw.)

6-1=5 and 3-2 =1 so the coordinates of the bathroom is (5,1)

Answer:

Step-by-step explanation:

your maximum "point" of the polynomial is the highest point that the curve makes which in this case is around x=-3.6 and y=17

The point of maxima for the given function is (-3.6, 17).

What is a function?

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

As per the graph of the function following conclusion are as below,

It has a maxima in second quadrant.

After the point of maxima, its value starts to decrease.

Then, it reaches it lowest value in fourth quadrant after which it increases again.

By examining the given options, the correct point of maxima can be found as (-3.6, 17).

Hence, the point of relative maxima for the graph can be evaluated as (-3.6, 17).

The angle formed by the Sun is labeled x deg A scientist measures the angle x and the distance y between the Earth and the shooting star. Which trig function would the scientist use to calculate the distance between the Earth and the Sun. (5 points) sin cos tan sin-1 cos-1 tan-1

Answers

Answer:

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, obtuse triangle, equilateral triangle and right angled triangle.

Trigonometric functions are functions used to show the relationship between an angle of a right-angled triangle and the ratio of two side lengths. Below are some trigonometric function:

sinθ = opposite/hypotenuse, cosθ = adjacent/hypotenuse, tanθ = opposite/adjacent.

Given the right angled triangle with angle x. and the hypotenuse y. We need to find the distance between the Earth and the shooting star.

d = distance between the Earth and the shooting star = adjacent side.

Therefore, the relationship between angle x, d and y can be gotten using the cos trig function.

cosθ = adjacent / hypotenuse

cos(x) = d / y

d = y * cos(x)

Daniel works at a nearby electronics store. He makes a commission of 15% on everything he sells. If he sells a laptop for $450, a wireless speaker for $82, and a set of wireless headphones for $120, how much money does Daniel make in commission?

Answers

Answer:

$97.80

Step-by-step explanation:

Answer:

$97.70

Step-by-step explanation:

So to find percent

450/100= 4.5 ,4.5x15= 67.5

82/100=0.82 0.82x15= 12.2

120/100=1.2 1.2x15=18

So do 67.5+12.2+18= $97.70

a) Solve 3(x - 5) = 18

Answers

Multiply out the brackets so...

3x - 15 = 18

Add 15 to both sides...

3x = 33

Divide by 3 on both sides...

x = 11
