Step-by-step explanation:

Answer 2

Answer:

x = 13

Step-by-step explanation:

Use pythagorean theorem since you have a right angle. So [tex]c^{2} = a^{2} + b^{2}[/tex]

so in this case [tex]c^{2} = 5^{2} + 12^{2}[/tex] so c = [tex]\sqrt{25+144}[/tex] and c = [tex]\sqrt{169}[/tex] so c = 13

Solve x – 2y = 12 if the domain is {–3, –1, 0, 2, 5}.

Answers

Answer:

Step-by-step explanation:

Answer:

answer is below

Step-by-step explanation:

x - 2y = 12

First step is to solve for y, so

[tex]x - 2y = 12[/tex]

Then, subtract x on both sides to isolate the variable, y.

[tex]-2y = -x + 12[/tex]

Divide both sides by -2

[tex]y = \frac{1}{2}x - 6[/tex]

------------------------------------------------------------------------------------------------------

The domain is {-3,-1,0,2,5}

Domain is the set of x values

Range is the set of y values

We are given the domain x, we need to find out the y values using the equation: [tex]y= \frac{1}{2}x - 6[/tex]

[tex]y = \frac{1}{2}(-3) -6 = \frac{-15}{2} = -7.5\\\\y = \frac{1}{2}(-1) -6 = \frac{-13}{2} = -6.5\\\\y = \frac{1}{2}(0) -6 = -6\\\\y = \frac{1}{2}(2) -6 = -5\\\\\\y = \frac{1}{2}(5) -6 = -\frac{7}{2} = - 3.5[/tex]

therefore,

when x is -3: y = -7.5

when x is -1: y = -6.5

when x is 0: y = -6

when x is 2: y = -5

when x is 5: y = -3.5

Range is {-7.5, -6.5, -6 , -5, -3.5}

hope this helps and is right :)

Answers

you have to know that the sum of angles of any quadrilateral shape is equal to 360 after finding the value of X we substituted it in the unknown angles . Also you have to know that angle V is an inscribed angle so the arc which is opposite to is double the angle for example if the angle is equal to 2 so the arc must equal to 4

Rodrigo and Melissa went to the art supply store to buy drawing materials. Rodrigo bought 10
pencils and 7 felt-tip markers for a total of $19.00. Melissa bought 3 pencils and 5 felt-tip markers
for a total of $10.05. Which of the following systems of equations could be used to determine
the cost of one pencil, P, and one felt-tip marker, m?

Answers

Answer:

10P + 7m = 19 .......... 1

3P + 5m = 10.05 .......... 2

Step-by-step explanation:

Let the cost of pencil be represented by P, and felt-tip by m. So that;

Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.

⇒ 10P + 7m = 19 .......... 1

Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.

⇒ 3P + 5m = 10.05 .......... 2

From equations 1 and 2,

10P + 7m = 19 .......... 1

3P + 5m = 10.05 .......... 2

Multiply equation 1 by 3, and 2 by 10 to have;

30P + 21m = 57 ......... 3

30P + 50m = 100.5 ....... 4

Subtract equation 3 from 4,

30P - 30P + 50m - 21m = 100.5 - 57

29m =43.5

m = [tex]\frac{43.5}{29}[/tex]

= 1.5

m = 1.5

Substitute the value of m in equation 2,

3P + 5m = 10.05 .......... 2

3P + 5(1.5) = 10.05

3P = 7.5 = 10.05

3P = 3

P = 1.0

Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.

A triangle has sides with lengths of 5 centimeters, 12 centimeters, and 15 centimeters. Is it a right triangle

Answers

Answer:

Step-by-step explanation:

You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.

This is not true since 144+25 is 169, not 196

Answer:

No, it is not a right triangle.

Step-by-step explanation:

You can determine whether a triangle is a right triangle by using the pythagorean theorem.

a^2 + b^2 = c^2

c will always be the longest side of the triangle, so in this case you need to substitute 5 and 12 in for a and b and see if it simplifies to 15.

5^2 + 12^2 = c^2

25 + 144 = c^2

c^2 = 169

c = 13

C would be 13, not 15, so the triangle is not a right triangle

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.

Answers

Answer:

The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.

Step-by-step explanation:

Given - Amelia runs a catering business. Based on her records, her weekly

profit can be modeled by P= -2x² + 152x - 150, where x is the

number of meals she caters and P is her profit. When P is negative,

Amelia losses money.

To find - What is the least number of meals Amelia needs to cater in order

to begin making profit.

Proof -

As given, P = -2x² + 152x - 150

Now,

Above the break-even point, she only get profit

The break -even point is a point where there is no profit, and no loss.

Now,

For break-even point,

[tex]\frac{dP}{dx} = 0[/tex]

⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]

⇒-4x + 152 = 0

⇒- 4x = - 152

⇒4x = 152

⇒x = [tex]\frac{152}{4}[/tex] = 38

∴ we get

If Amelia caters at least 38 meals , then she makes Profit.
