If f = {(0,2), (2,6), (3,15),(4,9)} and g = {(3,4), (2,1),(4,6), (5,9)},
what is (f x g)(3)?

Answers

Considering the given relations, the value of the multiplication of f(x) and g(x) at x = 3 is given by:

(f x g)(3) = 60.

What is the multiplication of f(x) and g(x) at x = 3?

The multiplication is given by the multiplication of each of the numeric values at x = 3, hence:

(f x g)(3) = f(3) x g(3).

The values are found as follows:

The first relation has point (3,15), hence f(3) = 15.The second relation has point (3,4), hence g(3) = 4.

Hence the multiplication is given by:

(f x g)(3) = f(3) x g(3) = 15 x 4 = 60.

Step-by-step explanation:

Maria is ordering trophies for school. Company Christopher charges $3.50 for each trophy and a one-time engraving fee of $25. Company Asya charges $7.50 for each trophy and a one-time engraving fee of $17 Develop an equation where the two companies would be the same.

Answers

Answer:

An equation where the two companies would be the same is given as:

25 + 3.50x = 17 + 7.50x

Step-by-step explanation:

Let the number of trophies ordered be represented by x

Maria is ordering trophies for school. Company Christopher charges $3.50 for each trophy and a one-time engraving fee of $25.

$25 + $3.50 × x

25 + 3.50x

Company Asya charges $7.50 for each trophy and a one-time engraving fee of $17

$17 + $7.50× x

17 + 7.50x

An equation where the two companies would be the same is given as:

Company Christopher = Company Asya

25 + 3.50x = 17 + 7.50x

Simplifying further:

Collect like terms

25 - 17 = 7.50x - 3.50x

8 = 4.00x

x = 8/4

x = 4

Hence, the two companies would be the same after 4 trophies.

Which statement regarding the triangle is correct?

A. The triangle is an equilateral triangle.

B. The triangle is an isosceles triangle.

C. The triangle is an obtuse triangle.

D. The triangle is a right triangle

Answers

Answer:

D

Step-by-step explanation:3,4,5 is a pythagorean triple, making it a right triangle

Answer:

D

Step-by-step explanation:

If you use the Pathagorean theorum where [tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex] and plug in the number you were given, you get [tex]3^{2}[/tex] + [tex]4^{2}[/tex] = [tex]5^{2}[/tex]  or 9 + 16 = 25 which is correct.

So this has to be a right triangle.

You can also eliminate answer A because you already know none of the sides are equal so it can't be equilateral.

You can eliminate answer B because you already know that no two sides have an equal length so it can't be defined as isosceles.

You can eliminate answer C because if it were obtuse, the 3rd side (5) would have to be a lot longer.

2(a-c)=4a solve for a​

Answers

Answer:

Here you go :)

So, you can't really answer this, but you can simplify it.

Simplifying

2(a + -1c) = 4a

(a * 2 + -1c * 2) = 4a

(2a + -2c) = 4a

Solving

2a + -2c = 4a

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4a' to each side of the equation.

2a + -4a + -2c = 4a + -4a

Combine like terms: 2a + -4a = -2a

-2a + -2c = 4a + -4a

Combine like terms: 4a + -4a = 0

-2a + -2c = 0

Add '2c' to each side of the equation.

-2a + -2c + 2c = 0 + 2c

Combine like terms: -2c + 2c = 0

-2a + 0 = 0 + 2c

-2a = 0 + 2c

Remove the zero:

-2a = 2c

Divide each side by '-2'.

a = -1c

Simplifying

a = -1c

Please help me find all 3 !

Answers

Answer:

m<P = 60 degrees

Step-by-step explanation:

All sides of the triangle are equivalent to each other.

All three sides of the triangle equal 180 degrees total.

Since there are 3 sides, we divide 180 by 3 to find the measurement for all sides

180 ÷ 3 = 60

Q = 60 degrees

P = 60 degrees

R = 60 degrees

Check your work by adding all three sides together to equal 180:

60 + 60 + 60 = 180

180 = 180

Answer:

Ok so 25$ for an adult. there are x adults so x times 25 is equals to $25x

13 dollars per child and y children so $13y

$20 for each pensioner and p pensioners so $20p

when adding these notice that none of the variable(latters) are the same so n adding will take place leaving the answer

$25x + $13y + $20p

a) $25x

b) $13y

c) $20p

d) $25x + $13y + $20p

Answer:

a) $25x, this is because if there are x number of adults coming, and $25 is the per adult charge, then irrespective of the number of adults coming this will be the equation. Eg : x = 5 So, $25 * 5 = $125

b) $13y, this is because if there are y number of children coming, and $13 is the per child charge, then irrespective of the number of children coming this will be the equation. Eg : y = 4 So, $13 * 4 = $52

c) $20p , this is because if there are x number of pensioners coming, and $20 is the per pensioner charge, then irrespective of the number of pensioner  coming this will be the equation. Eg : p = 2 So, $20 * 2 = $40

d) so, the total will be, = $25x + $13y + $20p
