if you enter the equation into a calculator it will do it for you. If you want to do it with a calculator heres how to. You would move the decimal to the first whole number for example in this case 2. How many places is that? 3. Whenever a decimal point moves to the right the spot is negative. You would then write it 2.6 with 10 (exponent -3)
Answer:
Step-by-step explanation:
To rewrite in scientific notation means to add an exponent such as e-3 in this case or [tex]10^{x}[/tex] where x is the exponent.
you would convert -0.0026 to -2.6e-3 or [tex]-2.6*10^{-3}[/tex]
The basic way of converting to scientific notation is to move your number a certain amount of decimal places until there is one number left before the decimal mark. Then the amount of values moved turns into you're exponent. A negative exponent means your are going towards a smaller number. Make sure to keep the current sign of the number
Find the rate of change between the following points:
(2,-1)
(-6,-5)
The rate of change between (2,-1) and (-6,-5) is 1/2.
What is the rate of change?
The slope is the ratio of the rate of change between two points (also known as the "slope") to (the change in the x coordinate).
Let (x,y)=(2,-1), (m,n)=(-6,-5)
Rate of change=(n-y)/(m-x)=(-5-(-1))/(-6-2)=1/2.

Estimate using compatible numbers 1,710 divided by 32
Compatible numbers are close in value to the real numbers, which simplifies problem-solving and estimation of the solution. 1,7,10/32 has a quotient (integer division) of 53 and a remainder ("leftover") of 14. The dividend is 1,7,10, while the divisor is 32.
Explain about the compatible numbers?Compatible numbers are those that divide equally into each other and are near to the numbers they are replacing. The outcome of a division is the quotient. 55,304 is not too far away from 56,000. 800 splits equally into 56,000 and is reasonably near to 875.
Our minds can occasionally spin when we are asked to find the total (in addition), difference (in subtraction), product (in multiplication), or quotient (in division). By rounding each number to the closest ten, twenty, fifty, or hundred, we employ suitable numbers to make the problem simpler to figure out mentally.
Numbers that are simple to mentally add, subtract, multiply, or divide are said to be compatible. To estimate a calculation, substitute compatible numbers for the actual numbers. Since it is simple to mentally calculate the sum of 800, the numbers 500 and 300 can be added together.

The smallest positive integer is 267 that should be multiply with given series.
What is meaning of series?
A series in mathematics is the total of a given set of terms. Real or complex numbers are typically used in these terms, but considerably more generality is conceivable.
Given series is 3, 6, 9, .... , 2400.
Assume that n should be multiply with the given series.
The series becomes 3n, 6n, 9n, .... , 2400n.
Now add the series:
(3n + 6n + 9n + ....+ 2400n)
Taking common 3n:
= 3n( 1 + 2 + 3 + ...+ 800)
Apply the formula the sum of the first n positive integers is n(n+1)/2
= 3n ×{800(800+1)}/2
=3n × 400 × 801
= 3n × 4 × 100 × 3 × 3 × 89
= (4 × 100 × 3 × 3) × (3 × 89) × n
The product of (4 × 100 × 3 × 3) is a perfect square. But 3 × 89 is not a perfect square. Thus n = 3 × 89 = 267.

Question 2 of 10 Which of the following is equal to the fraction below? (5/8)
The fraction that is equivalent to the fraction expression given as 5/8 is 40/64
How to evaluate the expression?From the question, we have the following fraction expression that can be used in our computation:
Fraction = 5/8
The above expression is a fraction and at the same time it is a rational number
The denominator of the fraction is 8
So, we start by rationalizing the expression by the fraction
This is represented as
5/8 = 5/8 * 8/8
Evaluate the products of the numerator
So, we have the following representation
5/8 = 40/8 * 1/8
Evaluate the products of the denominator
So, we have the following representation
5/8 = 40/64
The above expression cannot be further simplified
Hence, the equivalent expression of the fraction is 40/64

24.15 as a two significant figures?
24.15 as two significant figures is 24.
What are significant figures?All significant figures are those that enhance the overall worth of the number's meaning. Numbers are frequently rounded to avoid repeating quantities that are not significant. When rounding, one must be careful not to lose precision. Sometimes the purpose of rounding numbers is simply to make them simpler.
What are the significant figure's rules?Use the following guidelines to decide which numbers are important and which are not:
1) A decimal number less than 1 is not affected by the zero to the left of it.
2) The placeholders for all trailing zeros are all insignificant.
3. There should be significance between non-zero numbers.
4) Every non-zero number has meaning.
5) A number is rounded if it has more digits than the necessary number of significant ones. For instance, 432,500 is rounded up to 433,000 to three significant digits using the half-up (regular) method.
6) Zeros at the end of numbers that are not important but are left in because eliminating them would change the number's value. The 000 in 433,000 in the example above cannot be removed without converting the number to scientific notation.
Given the number, 24.15
We have to convert it to two significant figures, so we will consider the only two figures before the decimal point. So, the number up to two significant figures is 24.

When the p-value is used for hypothesis testing, the null hypothesis is rejected if?.
If the p-value is less than or equal to the selected significance level, the null hypothesis is rejected; otherwise, it is not. In other words, if p, reject[tex]H_{0}[/tex]; if p>, do not reject [tex]H_{0}[/tex].
In null hypothesis testing, this criterion, also known as (alpha), is frequently set to 05. If there is less than a 5% chance that the null hypothesis would be accepted and a result as spectacular as the effects that result would occur, the null hypothesis is rejected. When this happens, the result is said to be statistically significant.
The null hypothesis would be rejected if a statistical test was conducted with a threshold of relevance = 0.1, 0.05, & 0.01.
If the P value is smaller than alpha, the preset level of statistical significance, the alternative hypothesis is considered instead of the null hypothesis.

What is Arithmetic progression ?
An arithmetic progression or arithmetic sequence ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.
Here the series is given
4, 7/4, -1/2, -11/4,.....
In series, take 1st and 2nd terms to know common difference.
the common difference is = 7/4 - 4
= (7 - 16) / 4 = -9/4
Now, take 3rd and 2nd term
common difference = -1/2 - 7/4
= (-2 - 7) / 4 = - 9/4
so, we get the common difference is -9/4.
By that we can clearly say that given sequence of series is a Arithmetic sequence.

The impact of different fertilizers on crop which yields six different fertilizers have been applied to one field. here, the number of treatments in the test are 6.
Treatments are the numerous values of the factor.
The factor here is the effect of various fertilizers on crop yields.
Six different fertilizers were used.
As a result, the number of treatments equals the number of different fertilizers used = 6.
Fertilizers supply essential nutrients such as nitrogen to crops, allowing them to grow larger, faster, and produce more food. However, overfertilization can be a problem because it causes greenhouse gas emissions and eutrophication.

How to identify the function in the graph?First, we can see that the shape of the graph is a "V", so we have an absolute value function.
We can see that the slope is 1 (for each horizontal square that the line moves, it also moves one vertically) , so our function will be of the form
y = |x - a| + b
Notice that the above function has a vertex at (a, b)

Answer:
128°
Step-by-step explanation:
it is a right triangle, the bottom right one is, from the drawing, 90 °, the sum of the internal angles of all the triangles is 180 °, so making 180 - 90 - 38 we have the missing internal angle of 52 °.

PLEASE SOLVE ALL
A) The equation is 22 + (d * 1/2) = 30
B) The plant that still have to grow 8 cm more
C) d = 16 days, d represents the number of days
Step-by-step explanation:
Given:
Initial height (basil plant at buying) = 22cm
Plant grows on everyday = 1/2cm
A) Given:
Total height (to be grown) = 30 cm.
The equation is,
Initial height+ ( number of days * plant grows on everyday) = Total height
22 + (d * 1/2) = 30 → equation 1
B) The plant that still have to grow = Total height - Initial height
= 30 - 22
= 8 cm
C) Solving the value d using equation 1:
22 = 30 - (d * 1/2)
44 = 60 - d
d = 16 days
Hence, A) The equation is 22 + (d * 1/2) = 30.
