Answer:
he will do 19 pushups
Step-by-step explanation:
He will do 19 push ups because the pattern Is going up by 3 each days so if you add 3 to 16 you will get 19!!!!!
Hope This Helped :)
First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
1. You have that t<span>he sum of three consecutive even integers is </span>

<span>, therefore, you can given the variable </span>

<span> to the first integer, the second even integer is </span>

<span> and the third one is </span>

<span>.
2. Calculate x:
</span>

<span>
</span>

<span> </span>

<span>
</span>

<span>
</span>

<span>
Therefore, the answer is:</span>
Answer:
3,000 meters
Step-by-step explanation:
recall that 1 kilometer = 1,000 meters
hence
3 kilometers = 1,000 meters x 3 = 3,000 meters
If x^2+bx+16 has at least one real root, then the equation x^2+bx+16=0 has at least one solution. The discriminant of a quadratic equation is b^2-4ac and it determines the nature of the roots. If the discriminant is zero, there is exactly one distinct real root. If the discriminant is positive, there are exactly two roots. The discriminant of <span>x^2+bx+16=0 is b^2-4(1)(16). The inequality here gives the values of b where the discriminant will be positive or zero:
b^2-4(1)(16) ≥ 0
</span><span>b^2-64 ≥ 0
(b+8)(b-8) </span><span>≥ 0
The answer is that all possible values of b are in the interval (-inf, -8]∪[8,inf) because those are the intervals where </span>(b+8)(b-8) is positive.
