Which is the correct solution to the expression 4^8? Use the scientific calculator given in this course.

Answer:

∠BAC = 45° is the measure.

Step-by-step explanation:

In a square all sides are equal and all the angles are 90°.

We have to measure the angle BAC.

since both the sides AB and BC of the triangle BAC are equal. Therefore angles opposite to these sides ∠BAC and ∠ACB will be equal.

Since ∠BAC + ∠ACB + 90° = 180° ( Sum of all angles of ΔABC = 180°)

∠BAC + ∠BAC + 90° = 180°(∠BAC = ∠ACB)

2∠BAC = 180 -90 = 90°

∠BAC = 90/2 = 45°

∠BAC = 45° is the answer.

Final answer:

To subtract two polynomials, change the sign of the second polynomial and combine like terms. The result of subtracting (5x^2-3x-2) and (-2x^2-x+10) is 7x^2 - 2x - 12.

Explanation:

To subtract the given polynomials, (5x^2−3x−2) and (−2x^2−x+10), we need to change the sign of each term in the second polynomial and then combine like terms with the first polynomial. This is similar to subtracting negative numbers, where subtraction turns into addition when the number being subtracted is negative.

The subtraction process step-by-step is as follows:

Change the signs of the second polynomial: +2x^2 + x - 10

Add the results to the corresponding terms in the first polynomial:

5x^2 + 2x^2 = 7x^2

−3x + 1x = −2x

−2 − 10 = −12

So the answer to the subtraction in standard form is 7x^2 − 2x − 12.

Answer:- D is the right answer. 'Feet' is most appropriate unit to measure this distance.

Explanation:-

Given distance =.

[tex]=8.5\times10^{-2}\text{ miles}=\frac{8.5}{100}\text{ miles}=0.085\text{ miles}[/tex]

We know that the units of length near to the mile is kilometers and feetsuch that 1 mile = 1.6093 km

1 mile = 5280 feet

Thus 'feet' is most appropriate unit to measure this distance.

Then the given distance[tex]=0.085\text{miles}=0.085\times5280\text{ feet}=448.8\text{ feet}[/tex]

The inequalities are among the constraints for the given situation is,

[tex]12x+8y\geq 1000[/tex]  and [tex]x+y\leq 200[/tex]

Explanation:

Let x represents the number of regular ticket sold.

and y represents the number of student ticket sold.

then, 12x represents the regular tickets at $12 each,

and 8y represents the student tickets at $8 each.

As the manager wants to collect at least $ 1000 from the ticket sale or we can say that the manager wants $ 1000 or more from the ticket sale.

then, we have the inequalities for this;

[tex]12x+8y\geq 1000[/tex]

As, the theater can seat at most 200 people or we can also say that the theater can seat 200 or less people .

therefore, the inequalities for this we have;

[tex]x+y\leq 200[/tex]

Therefore, the inequalities are among the constraints for the given situation is,

[tex]12x+8y\geq 1000[/tex]  and [tex]x+y\leq 200[/tex]

 14 students have red hair

Answer:

There are 14 students at Hamilton Middle School having red hair.

Step-by-step explanation:

The total number students at Hamilton Middle School is 700. And it has been given that 2% of the total number of students have red hair.

Hence, in order to find the number of students having red hair, we can find 2% of 700.

[tex]\text{Number of student having red hair}=0.02\times 700\\=14[/tex]

Therefore, 14 students at Hamilton Middle School have red hair.

Answer:

ccccccccccccccccccccc

Step-by-step explanation:

The false statement is |-9| ≠ |9|.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

For example, In the 12U Softball division, Olivia gets chosen. What is Olivia's age? Olivia's age is unknown to you because the word "equals" is missing. However, since you are aware that she should be under or equal to 12, you can write Olivia's Age ≤ 12. This is a real-world example of an inequality.

Given:

-22 < 3 is true.

|-1| ≥ 0

It is true because |-1| is +1. which is greater than 0.

|-9| ≠ |9|

It is false because |-9| = +9 and |9|= 9 which are equal.

-7 ≤ -5

It is true because the smaller the small the negative number the greater its value.

Answer:

[tex]\frac{A1}{A2}[/tex]

Step-by-step explanation:

We are give that the distance travelled by the bird is A1.

And the time taken to fly this distance is A2.

Now we will find the speed with the formula mentioned below:

[tex]Speed=\frac{Distance}{time}[/tex]

Replacing Distance as A1 and Time as A2. We get speed of the bird as

[tex]\frac{A1}{A2}[/tex]

the bison runs 3520 feet per minute

convert that to miles per hour

3520/5280 = 2/3 of a mile per minute

To write 'a hundred and one thousand dollars' in numbers, combine the place values to get $101,000. The number 101 represents 'one thousand' plus 'one hundred,' followed by 'thousand,' which is represented by three zeros after 101.

Writing 'a hundred and one thousand dollars' in numbers involves understanding the place value of numbers and how to represent large numbers. In the decimal number system, the place values increase as powers of 10 from right to left, starting with the 1's place, 10's place, 100's place and so on. When dealing with large numbers, we use the powers of 1000, such as thousand (103), million (106), and billion (109).

To write 'a hundred and one thousand dollars' in numbers, you would write $101,000. Here, 'hundred' refers to the 100's place, and 'one thousand' refers to the 1,000's place. Therefore, you have one thousand plus one hundred, which is '101' followed by the 'thousand' represented by three zeros to make 101,000. When writing amounts in dollars, you use the dollar sign '$' in front of the number.

It's essential to remember that when expressing large numbers in written form, no apostrophes are used for the plurals. Also, in general, we use numerals to express numbers 10 and above, which helps in clarity and readability, especially when dealing with money or scientific notation.
