hopefully this makes sense.

The rotated triangle by 180° counterclockwise about the origin is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

The coordinates of the triangle are given as:

[tex]\left[\begin{array}{ccc}0&-3&5\\0&1&2\end{array}\right][/tex]

The rotation is given as:

180° counterclockwise about the origin.

The rule of 180° counterclockwise about the origin is:

(x,y) ⇒ (-x,-y)

Using the above rule, we have:

[tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

Hence, the rotated triangle is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

The person who paints more is given by the inequality equation 3/5 >  4/7

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the number of canvas be 35 ( LCM of 5 and 7 )

Now , when you divide 35 into 5 sections and paints 3 of them ,

The fraction A = 3/5

And , when your friend divide 35 into 7 sections and paints 4 of them

The fraction B = 4/7

And , the inequality equation is A > B

Substituting the values in the equation , we get

3/5 > 4/7

Hence , the one who paints more is you with 3/5 of the canvas

The volume of the given hemisphere is 59131.7 inches³.

What is a hemisphere?

Hemisphere is the exact one-half of the sphere.

given, diameter of the hemisphere is = d = 60.9 inches

Therefore, radius = d/2 = 60.9/2 inches = 30.45 inches.

Hence, the volume = (2/3) × π × r³ =  (2/3) × π × (30.45)³ inches³ = 59131.7 inches³.

Answer:

15

Step-by-step explanation:

The x-intercepts -3 and -5 are also "roots" of the polynomial.  The corresponding factors are (x + 3) and (x + 5).  Multiply the constants together:  3*5 = 15.  This is the desired constant term.

Note that your f(x) = x2 + 8x +   should be written   f(x) = x^2 + 8x +       ...    The " ^ " denotes exponentiation.

Check:  Multiply (x + 3) and (x + 5) together and compare the result to the given polynomial with constant term 15:

f(x) = (x + 3)(x + 5) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15.  This matches!

Answer:

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

Step-by-step explanation:

2a + 3b = 19 equation 1

1a + 4b = 17 equation 2

Multiply equation 2 by 2

2a + 8b = 34 equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

The sum of the numbers 13 + 13 + 13 is 39.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given expression is,

13 + 13 + 13

Here 13 is added to itself three times.

When 13 added to 13, we get 13 + 13 = 26

Again if we add the number 13 to 26, we get 13 + 26 = 39

13 + 13 + 13

= 26 + 13

= 39

This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.

Hence the number 13 added to itself three times gives 39.
