8. Graph the following equation: y = x2 + 4x - 5
Dennis_Churaev [7]

Answer:

Given: y = x2 + 4x – 5

Find the following

y-intercept

x-intercepts or the zeros of the functions or roots

graph of the function, given vertex is at (-2, -9)

Solve the system of linear equations      – x + 6y = 8        2x + 5y = 3

Write the names of curves, given their equations:  

x2/16 + y2/9 = 1

3y = 2x + 5

(x - 5)2 + (y + 6)2 = 25

x2/16 – y2/25 = 1

y = 2x2 + 10x + 25

Write down the first five terms of the arithmetic progression with the first term 8 and common difference 7, then find the 17th

Write down the first five terms of the geometric progression with the first term 3 and common ratio 2, then find the 17th

What are possible units for impulse? Check all that apply.
vivado [14]

Answer:

N s or Kg m/s

Step-by-step explanation:

Impulse is the product of the force and time or mass and velocity.

Impulse = force x time , or

Impulse  = mass x velocity

Therefore; the SI units of impulse is newton-second (N · s). Reduced to base units in the International System of Units ( SI ), a newton-second is the equivalent of a kilogram-meter per second (kg · m/s).

The function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative
iragen [17]

Answer:

"The range of the function is all real numbers less than or equal to 9."

Step-by-step explanation:

For this question the domain is (-∞,∞)

The range is all numbers less than 9 (the y-coordinate of the vertex)

The reason the numbers are less than 9 is because the graph is concave down (aka it looks like a frowny face)

Therefore the answer is "The range of the function is all real numbers less than or equal to 9."
