Answer:
D (i hope)
Step-by-step explanation:
When you minus the highest to the lowest it is added by 10 so
160-140= 20
140-110=30
110-70= 40
70-20= 50
I had added 10 to 160 and got 170
Listen ducky:
160-140=20
140-110=30
110-70=40
70-20=50
20+30+40+50+10 (we need to add 10 on every part because of the question), so 10+10+10+20+30+40+50=170
The answer is D, my dear duck
Left Riemann sum approximation Question...
The left Riemman sum approximation for f(x) = x^5, between x = 0 and x = 5, considering 5 intervals, is given as follows:
5.3248.
How to obtain the Riemman sum approximation?First we must obtain the Delta value, which is the difference between the bounds of the integral, divided by the number of integrals, thus:
[tex]\Delta_x = \frac{b - a}{n} = \frac{2 - 0}{5} = 0.4[/tex]
Then the values of x at which the numeric values are calculated are obtained as follows:
[tex]x_i = a + \Delta_x(i - 1)[/tex]
Thus the values of x are of:
[tex]x_1 = 0[/tex].[tex]x_2 = 0.4[/tex][tex]x_3 = 0.8[/tex][tex]x_4 = 1.2[/tex][tex]x_5 = 1.6[/tex]The numeric values are given as follows:
f(0) = 0^5 = 0.f(0.4) = 0.4^5 = 0.01024.f(0.8) = 0.8^5 = 0.32768.f(1.2) = 1.2^5 = 2.48832.f(1.6) = 1.6^5 = 10.48576.Then the Riemann sum approximation for the integral is given as follows:
[tex]\sum_{i = 1}^{n} \Delta_x f(x_i)[/tex]
Thus:
0.4(0 + 0.01024 + 0.32768 + 2.48832 + 10.48576) = 5.3248.

x*x is x^2, because the ^2 simply means that the x is multiplying by itself
(Ex. if you had x^3, you would have x*x*x, or if you had x^4, you would have x*x*x*x and it goes the other way around as well, meaning x*x*x*x*x would be x^5)
Answer:
B. x²
Step-by-step explanation:
A number/variable multiplied by itself would be a power, in this case to the second power.
For example:
x*x*x = x³
How do I do this and show work
We are given the expression:
[tex]\frac{\sqrt{2} }{3} = -\frac{2}{3} Sin\theta[/tex]
[tex]\sqrt{2}} = -2 Sin\theta[/tex] [multiplying both sides by 3]
[tex]Sin\theta = \frac{\sqrt{2}}{-2}[/tex] [Dividing both sides by -2]
[tex]Sin\theta = \frac{-1}{\sqrt{2}}[/tex]
which means:
[tex]\theta = Sin^{-1}(\frac{-1}{\sqrt{2}} )[/tex]
[tex]\theta = -Sin^{-1}(\frac{1}{\sqrt{2}} )[/tex]
θ = -45° [because [tex]Sin^{-1}(\frac{1}{\sqrt{2}})[/tex] = 45°]
Hence, the answer is -45° OR (360-45) = 315°

Adella wants to have $10,000. 00 saved in 5 years. Her local bank offers an account at 4% APR
compounding monthly. How much would she need to deposit to reach her goal?
$8000. 33
$8191. 67
$8189. 67
$8219. 29
The deposit to be made to save $10,000 in 5 years is $8189.67 when compounded monthly.
What is compound interest?Compound interest is interest on a loan or deposit that is calculated on both the principal amount and the interest accumulated in previous periods. It differs from simple interest, which is calculated on the principal only. Compound interest can be more favorable to the lender and more expensive to the borrower. The frequency of compounding (annual, quarterly, monthly, etc.) also affects the total amount of interest earned or paid.
Given that:
A = $10,000
r = 4% = 0.04
t = 5 years
n = 12 (since the compounding is monthly)
P = ?
The compound interest is given as follows:
[tex]A= P(1+\frac{r}{n} )^{nt}[/tex]
Substituting the values in the formula we have:
[tex]10000= P(1+\frac{0.04}{12} )^{(12)(5)}\\\\10000= P(1+0.0033 )^{(60)}\\\\10000= P(1.0033 )^{(60)}\\\\10000= P(1.2185)\\\\P= \frac{10000}{1.2185} \\\\P=8189.67[/tex]

The total cost for Ben to buy 1 binder and P pencils is 2.25 + 0.75 P.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Cost of a binder = 2.25
Cost of a pencil = 0.75
We have to find the total cost for Ben to buy 1 binder and P pencils.
Cost of 1 binder = 2.25
Cost of P pencils = 0.75 × P = 0.75 P
Total cost of 1 binder and P pencils = 2.25 + 0.75 P
Hence the total cost for Ben to buy 1 binder and P pencils is 2.25 + 0.75 P.

Answer:
Since in this option the minute is paid at $0.40, the best option is 10 minutes for $ 4.
Step-by-step explanation:
Since four friends, Abe, Bob, Carl, and Darrel, are going to a fun park, and they want to ride go-karts, and the price to ride the go-karts is $ 2.15 for 5 minutes, $ 4.00 for 10 minutes, or $ 6.75 for 15 minutes, to determine which price is the best deal, the following calculations must be performed:
2.15 / 5 = 0.43
4/10 = 0.40
6.75 / 15 = 0.45
Therefore, since in this option the minute is paid at $ 0.40, the best option is 10 minutes for $ 4.

What is the gradient of 2x 3y 6?
The gradient of the linear equation 2x + 3y + 6 is (3/2).
The gradient of a linear equation in the form of y = mx + c is m, which represents the slope of the line. The slope is defined as the ratio of the change in y to the change in x. It represents the steepness of the line.
The equation 2x + 3y + 6 is not in the form of y = mx + c. It is in the form of Ax + By + C = 0, which is the general form of a linear equation. To find the gradient of such an equation we need to divide -A/B. In this case, the gradient of the line is -2/3.
The gradient of a line gives us the direction of the line, it is the slope of the line. It tells us how steep the line is and if it is going up or down. A positive gradient means the line is going up and a negative gradient means the line is going down.

The median number of hurricanes per year reaching the East Coast from 1944 through 2000 is two.
What is median number?Median number is the middle value of a set of numbers. It is the number found at the midpoint of a sorted data set, when all the numbers are arranged in numerical order from lowest to highest. The median number is used to determine the average of a set of numbers, and is often used to represent the central tendency of the data. To calculate the median, first arrange the numbers from lowest to highest, then locate the middle value. If there is an even number of values, the median is the average of the two middle numbers.
This is calculated by taking the middle value of the data set. In this case, there were 18 years with one hurricane, 16 years with two hurricanes, 13 years with three hurricanes, and six years with four hurricanes. Thus, the median number of hurricanes in this data set is two.

In convex hexagon $ABCDEF$, all six sides are congruent, $\angle A$ and $\angle D$ are right angles, and $\angle B$, $\angle C$, $\angle E$, and $\angle F$ are congruent. The area of the hexagonal region is $2116(\sqrt2 1)$. Find $AB$.
The area of the hexagonal region exists 2116(√2 + 1) then the value of AB is 046.
What is meant by convex hexagon?All of the inner angles and all of the vertices must be smaller than 180 degrees for a convex hexagon. There are both regular and irregular convex hexagons.
There are no angles inside a convex hexagon. More specifically, no internal angle may exceed 180 degrees. Any internal angle that exceeds 180 degrees is concave.
Let the side length be x
The diagonal BF = √(AB² + AF²) = √(x² + x²) = x√2.
Then the areas of the triangles AFB and CDE in total exists (x²/2) × 2, and the area of the rectangle BCEF equals x × x√2 = x²√2.
Let the equation be
2116(√2 + 1) = x²√2 + x²
simplifying the above equation, we get
2116(√2 + 1) = x²(√2 + 1)
2116 = x²
x = 46
Therefore, the value of AB exists 0.46.

Line plot: what is it?A line graph, liner plot, or line chart is a graph that uses lines to link the individual data points. For a specific time period, quantitative values are displayed as a line graph. Line graphs are widely used in finance to depict the past market movements of a securities or asset.
Here,
calculation
The number line indicates that there's more than or equal to 3 marks when there are 7 markings either on or to the right of 3. The fraction must first have the same denominators.
=> 3/8 x 2 = 6/16
=> 1/2 x 8 = 8/16, 3/8 x 2 = 6/16
=> 5/8 x 2 = 10/16, 1/2 x 8 = 8/16
Since they all have the same numerator, we can now compare them.
=> 3/16 - 1/16 = 2/16
=> 6/16 - 3/16 = 3/16
=> 8/16 - 6/16 - 2/16
