Find the midpoint of the following
two coordinates
Please help!!

Answers

They gave you the formula for doing this! Just substitute the x and y to the corresponding formula.

Order pairs: (7, 5) and (3, 3)

Work: x1 = 7
x2 = 3

y1 = 5
y2 = 3

Now substitute.

1.) (7 + 3)/2 = 10/2

5 = x

2.) (5 + 3)/2 = 8/2

4 = y

Answer: The midpoint is B. (5, 4)

What is the relationship between sin x and cos y?

Answers

Answer:

It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).

Cassidy the Clown does face painting at the city carnival. She paints 8 faces every 21 minutes. Write an equation that related the number of faces she paints (y) and the time she spends painting (x)
ANSWER WITH A PICTURE ASAP

Answers

Answer:

8y=21x

Step-by-step explanation:

i'm not sure how to draw this out in a picture but the equation is above.

like the question states, Cassidy paints 8 faces in every 21 minutes. the amount of time she spends painting one face would be figured out by dividing 21 by 8 giving you 2.625minutes so i would just say around 3 minutes. so to draw a picture maybe just draw 8 faces and then circle them and say 21 minutes and then put x (to show the time she spent painting each face) under the faces in the picture and then show your work solving this.

in order to find out the ratio of time spent drawing one person's face we have to take the information given and divide the total of 21 minute span by the 8 different faces she painted in order to find how long she spends on 1 face.

hope this helps, if it did please make sure to leave a like, rate, and give me the brainliest if possible!

A flower garden is in the shape of a right triangle. One leg of the triangle is 6 ft long and the hypotenuse is 10 ft long. If tulips can be planted every foot, how many tulips would the gardener put around the perimeter of the garden?

Answers

Answer:

Step-by-step explanation:

Using the Pythagorean Theorem we know

h^2=x^2+y^2

We can find the missing side

x^2=h^2-y^2, we know h=10 and y=6 so

x^2=100-36

x^2=64

x=8

So the perimeter is 10+6+8=24

So 24 tulips can be placed around the perimeter.

The expression (x^13)(x^6) is equivalent to x^p. What is the value of p?

Answers

Answer:

p=19

Step-by-step explanation:

since the instructions say that ([tex]x^{13}[/tex])([tex]x^{6}[/tex]) is equivalent to [tex]x^{p}[/tex], we can make the equation:

([tex]x^{13}[/tex])([tex]x^{6}[/tex])=[tex]x^{p}[/tex]

now, apply the laws of exponents; [tex]a^{m} * a^{n} =a^{m+n}[/tex]

in that case, since we're multiplying x to the 13th power by x to the 6th, the result is [tex]x^{13+6}[/tex], which is [tex]x^{19}[/tex]

the equation now:

[tex]x^{19}[/tex]=[tex]x^{p}[/tex]

since the exponents are at the same base, we can solve the equation

19=p

so p is 19

hope this helps :)
