Good luck on your quiz :)
Roots are the same as zeros, and you find them by factoring and solving for y. This one is easiest if done by "taking roots" method. Let's move the 176 over to the other side and then divide both sides by 4 to get the x^2 alone. If we do that have we get x^2 = -44. But we know that we cannot take the square root of a negative number without accounting for it by using the imaginary "i". Since "i" is equal to -1, let's rewrite that [sqrt-44] as [sqrt(-1)(44)]. Now let's simplify the 44 by finding its perfect square hidden in there: [sqrt(-1)(4)(11)]. Now, because -1 = i^2, we can rewrite that as well like this:
[sqrt(i^2)(4)(11)]. Both the i^2 and the 4 are perfect squares so that's what we pull out, leaving the 11 inside for an answer of x = +/- 2i[sqrt(11)]
Answer:
$116.53
Step-by-step explanation:
Bryan earn's 11.80 per hour. He is paid time and a half for hours worked over 8hrs in a day. So if you divide 11.80 by 2, you get 5.90.
11.80+5.90=17.70. This is the amount he gets paid if he works overtime.
If Bryan worked 9.25 hrs yesterday, we already know that he made $94.40 in 8 hours. We have to find the amount he got paid for working over time.
The remaining hours are 1.25. We can add $17.70 to 94.40 to get 112.10. Now we have to figure out the remainder which is a quarter of an hour. Multiply 17.70 by .25 and you will get 4.43.
The total amount he got paid for working over time was $116.53.
Answer:
height: 7 in
base: 14 in
Step-by-step explanation:
Let the height of the triangle equal x. This means that the base can be represented by the expression 2x. Now we plug these values into the area formula for a triangle:
A = bh / 2
49 = x * 2x / 2
And simplify
49 = x^2
We can find the square root of both sides to get x = 7, so the height is 7 inches. Since the base is twice the height, it is 14 inches.
