Answer:

8.8×10^12

Step-by-step explanation:

4×10^4 = 40000

2.2×10^8 = 220000000

220000000×40000=8800000000000

8800000000000 = 8.8×10^12

The points did the student lose is 15.

20 questions make up a test. If the response is accurate, the test provides 3 points, and if it is erroneous, 1 point is deducted. A student gave wrong answers to five questions.

To toal number of question = 20

Points for 20 question = 20 × 3

= 60

( because 3 points for 1 correct answer and 1 point for 1 incorrect answers )

So, the number of incorrect questions = 5

Points for 5 questions = 5 × 1

=5

A student attempt correct question = 20 - 5 = 15

Points for 15 questions = 15 × 3

=45

The students lose points = 60 - 45

The Red Savina Habanero is 6. 13 times hotter than the Thai Pepper. Option A

A ratio can be defined as the comparison of two or more numbers on the basis of their sizes in relation to each other;

Given that;

To determine the ratio, we have to divide Red Savina Habanero hotness rating by Thai Pepper hotness rating

This is represented as;

= 4.6 x 10^5 /  7.5 x 10^4

= 6. 13 times

The Red Savina Habanero is 6. 13 times hotter

Thus, the Red Savina Habanero is 6. 13 times hotter than the Thai Pepper. Option A

By taking the quotient between the ratings, we can see that  Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

We know that the Thai Pepper has a hotness rating of 7.5*10⁴, while the Red Savina Habanero has a hotness rating of 4.6*10⁵.

We want to see how many times hotter is the Red Savina Habanero than the Thai Pepper, to find that we need to take the quotient between the rating for the Habanero and the rating for the Pepper.

It gives:

Q = (4.6*10⁵)/(7.5*10⁴)

This can be rewritten as:

Q = (4.6/7.5)*(10⁵/10⁴)

   =0.613*(10 ⁵⁻⁴) = 0.613*10

Now, we want to write this in scientific notation, so we need to have a single digit different than zero in the left side of the decimal point.

Then we can rewrite:

0.613*10 = 6.13*10⁰ = 6.13

We conclude that the Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

Step-by-step explanation:

The range for the given domain is represented by set {-9,-7,-5,-3,-1} or the interval   [-9,-1] .

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

The question gives:

You should find the values of y for each value of x in the domain. Thus

       y=2*(-2)-5=-4-5= -9

       y=2*(-1)-5=-2-5= -7

       y=2*(0)-5=0-5= -5

The statements that are also valid based on the proportion are given as follows:

The proportion for this problem is given as follows:

(m/n) = (p/q).

Applying cross multiplication, the proportion can also be written as follows:

mq = pn.

Then each statement in which the application of cross multiplication results in this product is valid.

Thus the third, fourth, and fifth options are the correct options, as the application of the cross multiplication for each of them results in the expression mq = pn.

For the first, second and sixth statements, they are not valid, as the application of cross multiplication would result in a different expression to mq = pn.

Part 1) "The difference of m and 12"
This simply means subtracting 12 from m. Therefore, we get [tex](m - 12)[/tex].

Part 2) "Twice the difference of m and 12"
This means we should double the same difference we got in Part 1. Therefore, we get [tex]2(m - 12)[/tex].

The rectangular coordinates of each point are (x, y) = (- √2, √2), (x, y) = (2√3, 2) and (x, y) = (- 1 / 3, - √3 / 3).

Polar coordinates are of the form (r, θ), where r and θ are the the distance with respect to the origin and the direction in standard position. The coordinates in rectangular form can be described in polar terms by the following formula:

(x, y) = (r · cos θ, r · sin θ)

Now we find the polar coordinates equivalent to each pair of rectangular coordinates:

Case 1

(x, y) = (2 · cos (3π / 4), 2 · sin (3π / 4))

(x, y) = (- √2, √2)

Case 2

(x, y) = (- 4 · cos (7π / 6), - 4 · sin (7π / 6))

(x, y) = (2√3, 2)

Answer:

Step-by-step explanation:

You want to identify the integral of f(x)=100x^99+20x^4+2/x^2+3/x+9.

For all powers of x except x^-1 = 1/x, the power rule applies:

  [tex]\int{x^n}\,dx=\dfrac{x^{n+1}}{n+1}[/tex]

The power rule cannot apply when n=-1, as that would make the integral undefined. Instead, the integral is ...

  [tex]\int{x^{-1}}\,dx=\ln{(x)}[/tex]

Any constant multiplier (k) of the expression being integrated will be a constant multiplier of the integral of that expression.

Any indefinite integral may have a constant (c) added.

  [tex]\displaystyle k\cdot\int{f'(x)}\,dx=k\cdot f(x)+c[/tex]

Applying these rules, we get the integral shown in the attachment.

3200 meters by using the units of conversion will be equal to 3.2 km.

We are given:

3200 meters.

We know that the unit of conversion for the meters and kilometers is given by:

1 km = 1000 m

1 m = 1 / 1000 km

For 3200 m, we will use the operation of multiplication.

So, we get that:

3200 m = 1 / 1000 × 3200 km

3200 m = 3.2 km.

Therefore, we get that, 3200 meters by using the units of conversion will be equal to 3.2 km.

The equation of the line is y = 2x + 4.

Here, we are given that a line passes through point (0.5, 5) and parallel to the line 4x - 2y = 11.

Now, two lines that are parallel to each other will have the same slope.

Therefore, let us first find the slope of line 4x - 2y = 11.

Let us convert the equation to y = mx + c form where m is the slope and c is the y intercept.

4x - 2y = 11

4x - 11 = 2y

2y = 4x -11

y = 4x/2 - 11/2

y = 2x - 11/2

Thus, the slope of line 4x - 2y = 11 is 2

Hence, the slope of the line parallel to it will also be 2.

Now, the equation of a line can be found by the slope intercept form as-

y - y1 = m(x - x1)

here, x1 = 0.5 and y1 = 5

y - 5 = 2( x - 0.5)

y - 5 = 2x - 1

y = 2x - 1 +5

y = 2x + 4

Thus, the equation of the line is y = 2x + 4.
