Answer:
D and E
Step-by-step explanation:
f(x) = (x - 3)² - 25
x intercepts occur when y = 0
0 = (x - 3)² - 25
25 = (x - 3)²
±5 = x - 3
x = 8, or -2
A) g(x) = 2x + 2
0 = 2x + 2
x = -1 Nope
B) h(x) = 2x + 6
0 = 2x + 6
x = -3 Nope
C) q(x) = -4x + 11
0 = -4x + 11
x = 11/4 Nope
D) r(x) = -3x - 6
0 = -3x - 6
x = -2 YES
E) w(x) = 3x - 24
0 = 3x - 24
x = 8 YES
Answer:
the first one
Step-by-step explanation:
because the 12.3cm line at the top put that at the bottom multiply those and there you go
Answer:
The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.
Step-by-step explanation:
Choice A is the only one that is changing at a constant rate. The reason is that for all three other choices the new rate is based on a different amount after the percent has been applied or the doubling of the ants has been applied. The price per day for the lunch Is constant because whatever the number of days is the amount would always stay the same for each of those days.
Tan(a/2) = sin a / (1 + cos a)
tan(45/2) = sin(45) / (1 + cos(45)) = (1/√2) / (1 + 1/√2) = (1/√2) / (√2 + 1)/√2 = 1/(√2 + 1) = (√2 - 1)
