Subtracting is the same as adding, so by subtracting the equations, you get 2x=20, x=10, y: 30-7y=16, 7y=14, y=2, answer:(10,2)

Use the mapping shown above to show the value of the function f(x) at each point.
julsineya [31]

Answer:

The value of the function f(x) at each point is f(-1) = 5, f(0) = 3, f(1) = 5, f(2) = 11, f(3) = 21 ⇒ A

Step-by-step explanation:

Let us use the mapping shown to solve the question

∵ f(x) = y

∵ x is the domain

∵ y is the range

→ From the figure use x from the domain and y from the range, where

   each arrow pointed at the corresponding value y of x

∵ x = -1 and the corresponding value of y is 5

∴ f(-1) = 5  

∵ x = 0 and the corresponding value of y is 3

∴ f(0) = 3

∵ x = 1 and the corresponding value of y is 5

∴ f(1) = 5

∵ x = 2 and the corresponding value of y is 11

∴ f(2) = 11

∵ x = 3 and the corresponding value of y is 21

∴ f(3) = 21

The value of the function f(x) at each point is f(-1) = 5, f(0) = 3, f(1) = 5, f(2) = 11, f(3) = 21

The path of an underwater drone is modeled by quadratic function d, where x is the horizontal distance, in miles, from the launc
soldier1979 [14.2K]

Based on the vertex form equation, the statements that are true are:

A.) the drone reaches its minimum 25 miles from the launch site

C.) at its minimum, the drone’s depth is -180 meters.

<h3>Rewriting the equation in vertex form</h3>

Given:

x = horizontal distance, in miles, from the launch site

d(x)= depth below the surface of the water, in meters.

Equation= 0.4x ²- 20x + 70

Hence

Rewritten the given equation ( 0.4x ²- 20x + 70) in vertex form will be:

Vertex form: d(x)=[2(x-25)²÷5] -180

Vertex= -180, 25

Minimum=-180 at x=25

Therefore the correct option is A, C.
