Answer: <em>D</em>
Step-by-step explanation:
<em>Since < this has a line under it, it becomes a closed circle</em>
<em>And we can now assume the direction it is pointing in is left. </em>
Answer:
1. Quintic
2. -8x^5 + 10x^4
Step-by-step explanation:
1.
Quintic: Has a power of 5 for ex. -6x^(5) + 4x^3 + 3x^2 + 11
Cubic: x^(3) + 12x + 9
Quartic: x^(4) + 5x^3 - 6
Quadratic: x^(2) - x + 5
2.
-2x^2(-5x^2 + 4x^3)
(10x^4 - 8x^5) or (-8x^5 + 10x^4)
When multiplying numbers with exponents, multiply the numbers but add together the exponents.
I hope this helps!
Answer:
The speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Step-by-step explanation:
Given;
velocity of the ball, v = 17 mph
angle of inclination, θ = 22⁰
The horizontal component of the velocity is calculated as;
The vertical component of the velocity is calculated as;
Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Answer: H
Step-by-step explanation:
The slope can be found using two points and the formula (y2-y1)/(x2-x1)
if we use (0,-2) and (1,1), x1 = 0, y1 = -2, x2 = 1, y2 =1
plug these into the formula to get
(1- -2)/(1-0)
= 3/1
= 3
so the slope is 3, so the coefficient on the x would be 3 in the y = mx+b formula
b would equal the y-intercept or the number when x = 0
when x = 0, y = -2, so b = -2
plug these into y = mx+b to get
y = 3x -2
