Answer:
1.38 * 10^ -2
Step-by-step explanation:
.0138
We need 1 number to the left of the decimal
1.38 * 10^ something
We moved it 2 places to the right, that means our exponent is -2. If we had moved it to the left, our exponent would have been positive
1.38 * 10^ -2
<u><em>(The Explanation):</em></u> What we are given is that the car drives 45 miles each hour. Furthermore, you need to multiply the amount of hours desired to the miles to get a total mile.
<u><em>(Step-By-Step Instructions):</em></u>
<em>45(4) and 45(20) </em> Multiply
<u><em>The Answers:</em></u> 4 hours = 180 miles / 20 hours = 900 miles
Answer:
Step-by-step explanation:
If you call "5x-2x^2+1" an "equation," then you must equate 5x-2x^2+1 to 0:
5x-2x^2+1 = 0
This is a quadratic equation. Rearranging the terms in descending order by powers of x, we get:
-2x^2 + 5x + 1 = 0. Here the coefficients are a = -2, b = 5 and c = 1.
Use the quadratic formula to solve for x:
First find the discriminant, b^2 - 4ac: 25 - 4(-2)(1) = 25 + 8 = 33
Because the discriminant is positive, the roots of this quadratic are real and unequal.
-b ± √(discriminant)
Applying the quadratic formula x = --------------------------------
2a
we get:
-5 ± √33 -5 + √33
x = ----------------- = --------------------- and
2(-2) -4
-5 - √33
---------------
-4
