Step-by-step explanation:
Given:1st grade:
19%2nd grade:
14%3rd grade:
22%4th grade:
26%5th grade:
19%TOTAL : 205 students.To find -Since the total students have been given, we just have to find the percentage of the 205 students that are 5th graders (19%).
So this can be found out:
19% of 205
Solution:
Always use this formula to find a percentage:
% / 100 = Part / Whole replace the given values:
19 / 100 = Part / 205
Cross multiply:
19 x 205 = 100 x Part, or
3895 = 100 x Part
Now, divide by 100 and get the answer:
Part = 3895 / 100 = 38.95
Since decimal cant be a whole number round to nearest tenth:
First note that 38.95 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 38Fractional Part: 95To round 38.95 to nearest tenth means to round the numbers so you only have one digit in the fractional part.
We use the following rules to round 38.95 to the nearest tenth:
A) If the last digit in the fractional part of 38.95 is less than 5, then simply remove the last the digit of fractional part.B) If the last digit in the fractional part of 38.95 is 5 or more and the first digit in the fractional part is less than 9, then add 1 to the first digit of the fractional part and remove the second digit.C) If the last digit in the fractional part of 38.95 is 5 or more and the first digit in the fractional part is 9 then add 1 to the Integer part and make the fractional part 0.With 38.95, rule C applies and the answer is:
39.0

If functions f(5x)=f(5)+f(x) then f(1)=0.
What is a function?A relation is a function if it has only One y-value for each x-value.
Given that f(5x)=f(5)+f(x)
f of five times of x equal to f of five plus f of x.
We need to prove f(1) is equal to zero.
f(5x)=f(5)+f(x)
Let plug in x value as one
f(5×1)=f(5)+f(1)
f(5)=f(5)+f(1)
Subtract f(5) from both sides
f(1)=0
Hence, if functions f(5x)=f(5)+f(x) then f(1)=0.

Find the slope of the line through the pair of points: ( − 3 , 4 ) and ( 0 , 2 ) .
Answers
Answer:
[tex]-\frac{2}{3}.[/tex]
Step-by-step explanation:
1) the required slope can be calculated if to use the ratio:
slope=(y(B)-y(A))/(x(B)-x(A)), where x(A)=-3; y(A)=4; x(B)=0 and y(B)=2;
2) according to the formula above:
s=(2-4)/(0+3)=-2/3.
The slope of the line through the given points is: -2/3.
What is the Slope of a Line?Slope of a line= change in y / change in x = rise/run.
Given the points:
(-3, 4) = (x1, y1)
(0, 2) = (x2, y2)
Slope = (4 - 2)/(-3 - 0)

x^2=-10x-30 (Answer: { })
help and with explanation; will give brainliest
Answers
Answer:
Step-by-step explanation:
x² + 3x - 70 = 0
x² + 3x = 70
x² + 3x + (3/2)² = 70 + (3/2)²
(x + 3/2)² = 70 + 9/4 = 289/4 = (17/2)²
so
x + 3/2 = ±17/2
x = ±17/2 - 3/2
x₁ = 17/2 - 3/2 = 14/2 = 7
x₂ = -17/2 - 3/2 = -20/2 = -10
x² = -10x - 30
x² + 10x = -30
x² + 10x + (10/2)² = -30 + (10/2)²
x² + 10x + 25 = -30 + 25 = -5
(x + 5)² = -5
[tex]x+5 = \pm\sqrt{-5}\\x + 5 = \pm i \sqrt{5}\\x = -5\pm i \sqrt{5}\\\\x_1 = -5+ i \sqrt{5}\\\\x _2= -5- i \sqrt{5}\\[/tex]

Step-by-step explanation:
Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:
A)
8000 x 1.67 ^ n = f
B)
8000 x 1.67 ^ 6 = X
8000 x 21.691961596369 = X
173,535.692770952 = X
C)
(8000 - 1200 x 1 ^ n) x 1.67 ^ n = f
Therefore, there would be 173,535 lionfish after 6 years.

Answer: shifted by π/2 radians
Step-by-step explanation:
The function sine of 'x' can be equated to the function cosine of 'x' by shifting cosine by 180 degrees. In math words:
[tex]sin(x)=cos(x-180)[/tex]
The value 180 degrees in radians would be π/2. Therefore, in radians:
[tex]sin(x)=cos(x-\pi /2)[/tex]
The 'x' inside of the functions is called the argument, and the value added or subtracted to the argument is the phase. The correct answer would be that sine is equal to cosine shifted by a phase of π/2 radians
