73 degrees. This is because that they are corresponding angles.

Find the discriminant for this equation. x2 + 3x + 1 = 0

Answers

Answer:

Step-by-step explanation:

if ax^2 +bx + c ====>discriminant formula is b^2 - 4ac from the quadratic formula

x2 + 3x + 1 = 0

Then;

a=1

b=3

c=1

b^2 - 4ac = 3^2 -4*1*1

= 9-4

Describe how you regroup when you find the sum of 64 + 43?

Answers

To regroup, you simply break up the bigger numbers into smaller numbers that are more easily added together. We often regroup into numbers that end with 0 because they're easier to add. For example, you can break up 64 into 60 + 4 and 43 into 40 + 3. This will make addition easier, because you can first add together 60 and 40, which will equal 100. Then, you can add the smaller digits: 100 + 4 + 3 = 107.

Final answer:

Regrouping in addition, as in 64 + 43, involves adding numbers column by column from right to left. If the addition in a column results in a value of 10 or more, a 'carry over' or regrouping is done to the next column. The final resultant sum is 107.

Explanation:

To regroup when you find the sum of 64 + 43, you need to add the numbers column by column, moving from right (units) to left (tens, hundreds, etc.). In this case, add the right column (4 from 64 and 3 from 43) to get 7. Next, add the left column (6 from 64 and 4 from 43). The sum is 10. Since 10 is a two-digit number, the number in tens place (1) is carried over or regrouped to the tens column. To get the final answer, add the numbers in the tens column (including the carryover). This results in 107. In general, regrouping is a technique used in addition and subtraction to simplify calculations and solve problems more easily.

Solving a polynomial equation by factoring 36d^3-121d=0

Answers

For this case we must factor the following equation:

$36d ^ 3-121d = 0$

It is observed that both terms contain the variable "d", so we can take it out as a common factor:

$d (36d ^ 2-121) = 0$

On the other hand, we look for the factors of 36 and 121:

36: 1,2,3,4,6,9,12,18,36

121: 1, 11,121

The greatest common factor between both numbers is 1.

Thus, the expression is factored as:

$d (36d ^ 2-121) = 0$

Thus, one of the roots of the polynomial is 0.

$36d ^ 2-121 = 0\n36d ^ 2 = 121\nd ^ 2 = \frac {121} {36}\nd = \pm \sqrt {\frac {121} {36}}\nd = \pm \frac {11} {6}\n$

Answer:

$d (36d ^ 2-121) = 0\nd_ {1} = 0\nd_ {2} = \frac {11} {6}\nd_ {3} = - \frac {11} {6}$

Jonathan ran five days a week. The most he ran in one day was 3.5 miles. Write an inequality that shows the distance jonathan could have run any day this week

Answers

Answer: $x\leq17.5$

Step-by-step explanation:

Given: The number of days Jonathan ran = 5

The most he ran in 1 day = 3.5 miles

Therefore, the maximum distance he ran in a week= $5*3.5=17.5\ miles$

Let x be the distance Jonathan could have rum in a week, such that

$x\leq17.5$

Hence, the required inequality is $x\leq17.5$ .

ok so a week has 7 days so we have to include that in our inequality so it should look something like this 3.5 is less than or equal to 7 tell me is that one of your answer choices?
