Hope this helps, the y intercept is 3 ans the x intercepts are +1.3 and -1.3
Answers:
k = 13The smallest zero or root is x = -10
===============================
Work Shown:
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
Answer:
(6 × 3) divided by 8 and 3/8 × 6
Step-by-step explanation:
if you solve 6 × 3/8 you should get 18/8 which then simplifies to 9/4. if you go though each answer choice solving each problem you should get 9/4 and if you dont then that is not the answer. the first 2 answer choices equal 16 which is not 9/4 and the 4th answer choice will give you 4 and 6 × 8/3 gives you 48/3 which gives you 16 so only the 3rd and last answer choices are correct
Speed is the magnitude in a velocity. It is a scalar quantity so it does not have direction unlike velocity which is a vector quantity. Speed and velocity refers to the distance traveled by a moving object per unit of time. We calculate speed as follows:
Speed = distance / time = 84 miles / 2 hours
Speed = 42 miles per hour
