The first incorrect is the second step so choice B. ,bc. the exponents need assuming not multiply
hope helped
Answer:
The equation does not have a real root in the interval ![\rm [0,1]](https://tex.z-dn.net/?f=%5Crm%20%5B0%2C1%5D)
Step-by-step explanation:
We can make use of the intermediate value theorem.
The theorem states that if 
is a continuous function whose domain is the interval [a, b], then it takes on any value between f(a) and f(b) at some point within the interval. There are two corollaries:
- If a continuous function has values of opposite sign inside an interval, then it has a root in that interval. This is also known as Bolzano's theorem.
- The image of a continuous function over an interval is itself an interval.
Of course, in our case, we will make use of the first one.
First, we need to proof that our function is continues in , which it is since every polynomial is a continuous function on the entire line of real numbers. Then, we can apply the first corollary to the interval , which means to evaluate the equation in 0 and 1:
Since both values have the same sign, positive in this case, we can say that by virtue of the first corollary of the intermediate value theorem the equation does not have a real root in the interval . I attached a plot of the equation in the interval ![\rm [-2,2]](https://tex.z-dn.net/?f=%5Crm%20%5B-2%2C2%5D)
where you can clearly observe how the graph does not cross the x-axis in the interval.
Answer:
2 2/3
Step-by-step explanation:
Make them into improper fractions first.
11/2 - 17-6
Then multiply 11/2 so that they have common denominators.
33/6 - 17/6
Then solve.
33/6 - 17/6 = 16/6
Then convert back into a mixed number.
2 4/6 or 2 2/3
Marisol biked a total of 71 miles. On the other hand, she biked about 10 more miles on Wednesday than on Thursday.
<h3>How to round numbers?</h3>
The general rule is to move the decimal number to its nearest tenth. For example, 5.6 should be rounded as 6 but 5.1 should be rounded as 5.
Now, let's round the distance covered by Marisol each day:
- Monday: 12.3 = 12
- Tuesday: 14.1 = 14
- Wednesday: 17.7= 18
- Thursday: 11.8 = 12
- Friday: 15.2 = 15
<h3>What distance did Marisol covered?</h3>
To know this just add the distance every day:
- 12 + 14 +18 + 12 + 15 = 71 miles
<h3>How much more did she bike on Wednesday than on Thursday?</h3>
Distance covered on Wednesday - distance covered on Thursday
Note: This question is incomplete; here is the missing information:
- Monday 12.3
- Tuesday 14.1
- Wednesday 17.7
- Thursday 11.8
- Friday 15.2
