The required distance covered is 90 units

<h3>Distance formula</h3>

The formula for calculating the distance between two points is expressed as shown:

  • D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The required coordinates missing are (0, 42.78) and (90.42.78). Substiute the coordinate into the formula:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

D=\sqrt{(42.78-42.78)^2+(90-0)^2}\\D=\sqrt{(0^2+(90)^2}\\D = 90 units

Hence the required distance covered is 90 units

Which equation does not represent a function? Why? A) y = x2; There are two outputs for each input. B) y2 = 4x; There are two ou
natita [175]

Answer:

B) y² = 4x; There are two outputs for each input

Step-by-step explanation:

For an equation to be called a function, the input values for x must only result in a single output for y.

Based on this definition if a function, the functions y = x², y = -x and y = x are all functions because for any value of x imputed in them, we can only get one equivalent value of y.

The only exception is the function y²= 4x

For this function, for any value of x, there will be more than one output for y. Take x = 1 for example

y² = 4(1)

y² = 4

y = ±√4

y = ±2

This shows that y = 2 and -2

Also if x = 4

y² = 4(4)

y² = 16

y = ±√16

y = ±4

y = 4 and -4

No matter the value of x imputed, the output value y will always be two (a positive and a negative value)

Hence, option B is correct.

Solve for x please help
Fed [463]

Answer:

x = 5

Step-by-step explanation:

By remote exterior angle theorem:

(6 + 25x) \degree = (18x - 3)\degree  + 44\degree  \\ 6 + 25x = 18x - 3 + 44 \\ 25x - 18x = 41 - 6 \\ 7x = 35 \\ x =  \frac{35}{7}  \\ \huge \red{ \boxed{ x = 5}}
