Answer:

The required relation is: {(-2,3), (0,3), (1,1), (3,4), (4,6)}

Step-by-step explanation:

Consider the provided diagram.

Here the left side represents the input (X) values and the right side represents the output (Y) values.

The -2 has an arrow pointing to 3, so this becomes (-2,3).

The 0 has an arrow pointing to 3, so this becomes (0,3).

The 1 has an arrow pointing to 1, so this becomes (1,1).

The 3 has an arrow pointing to 4, so this becomes (3,4).

The 4 has an arrow pointing to 6, so this becomes (4,6).

Hence, the required relation is: {(-2,3), (0,3), (1,1), (3,4), (4,6)}

Because the coefficient of x^2 is -1, we know that a will be -1.  Knowing that the coefficient of x is -4, we can calculate that p=2.  Thus, we have -1(x+2)^2+q is our equation.  This is equal to -x^2-4x-4+q.  As the constant term must be 2, we can then see that q is 6.

As such, we have -1(x+2)^2+6=0 as our factorization.

To solve this equation, we can use the quadratic formula.  Plugging in values, we have:

\frac{4+-2 \sqrt{6} }{-2}
which is equal to: (when the fraction is simplified)
-2+- \sqrt{6}

A map has a scale of 5 in. = 15 mi. If you measured the distance between two cities to be 26 in. On the map, how many miles woul
Reil [10]

Answer:

Actual distance between the two cities given on the map = 78.0 miles

Step-by-step explanation:

Scale used for the actual distance between two cities on a map is,

5 in. = 15 mi.

\frac{5}{15} in. = \frac{15}{15} mi.

1 mi. = \frac{1}{3} in.

1 inch = 3 miles

Therefore, 26 inches on the map = 26 × 3

                                                        = 78 miles

Therefore, actual distance between the two cities given on the map = 78.0 miles

I have to find an equation for a table​
Anna35 [415]

Let's say imput is i and that output is o.

The formula is 2 ^ i = o

2^0 = 1

2^1 = 2

2^2 = 4

2^3 = 8

2^4 = 16

2^5 = 32

Notice how the numbers match?

Hope this helped :)

What + 89= 9(6+5) please solve for my answer and explain how you got your answer
nlexa [21]
The answer would be 10.

6 + 5 = 11
11 x 9 = 99

This means 9(6+5) = 99

99 - 89 = 10
