Answer:
x = 7.272727...
x ~= 7.27 (nearest hundredth)
x ~= 7.3 (nearest tenth)
Step-by-step explanation:
"Supplementary" means the angles add up to 180°.
100 + 11x = 180
11x = 80
x = 7.272727...
Answer:
Option A
Step-by-step explanation:
Degree of the polynomial function = 4
That means highest degree term of the given polynomial has power = 4
If the roots of a quadratic polynomial are a, b, c, d then the polynomial function will be,
f(x) = (x - a)(x - b)(x - c)(x - d)
It's given in the question that roots are x = -2, -1, 1 and 3
Therefore, polynomial function will be,
f(x) = (x + 2)(x + 1)(x - 1)(x - 3)
From the given options, graph A shows that the graph intersects the x-axis at x = -2, -1, 1 and 3
Therefore, Option A will be the answer.
6 is right. 7, the fraction is right, but the equation doesn't make sense. It would be .25, not 2.5.
I'll work through 8 with you, and it should help with the rest. Okay, so you have 6 possible outcomes: 1, 2, 3, 4, 5, and 6. The question is "What's the probably of not getting a 5?" Well, the probability of getting a 5 is 1/6, so not getting a 5 would be 5/6 or about 83.3%
Answer:
0.0176 (round the 5 up to 6 because of the 8)
Answer:
seconds

With conversion fractions, the denominator unit is always what you want to cancel out. In this case, we want to cancel out "seconds" because we want to effectively replace "seconds" with "minutes" (which is what conversions are really). The numerator is the unit we want to convert to. Take care to note that sometimes you'll need multiple conversions, and sometimes it's not going to involve one conversion fraction only.
Have a look at the attached image to get a better sense of what is going on. Note the red slash marks to indicate cancellations.
