0.582 times 10 what is value of the 2
Answer:
5.82
Step-by-step explanation:
0.582 x 10
=> Shift the decimal place by 1
=> 5.82
The required simplified value of the product is 5.82 and the value of 2 in the expression is 0.01 times.
To determine the value of 2 in the product of 0.582 times 10.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
Product = 10 * 0.582
Product = 5.82,
Where 2 is located at the thousandth place,
So, the value of 2 in 5.82 is 0.01 times of 2.
Thus, the required simplified value of the product is 5.82 and the value of 2 in the expression is 0.01 times.

(SHOW WORK) Write the slope-intercept form of the equation:
passes through (-2, 3) and is perpendicular to y = 1/4x - 4
Answer:
[tex]\displaystyle y = -4x - 5[/tex]
Step-by-step explanation:
We want to find the slope-intercept form of the equation that passes through the point (-2, 3) and is perpendicular to the line:
[tex]\displaystyle y = \frac{1}{4} x - 4[/tex]
Note that this line has a slope of 1/4.
Recall that the slopes of perpendicular lines are negative reciprocals of each other.
Since the slope of our old line is 1/4, the slope of its perpendicular line must be -4.
We are also given that it passes through the point (-2, 3). So, we can consider using point-slope form:
[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]
Let (-2, 3) be (x₁, y₁) and substitute -4 for the slope m. Hence:
[tex]\displaystyle y - (3)= -4 (x - (-2))[/tex]
Convert into slope-intercept form. Simplify:
[tex]\displaystyle \begin{aligned} y -3 &= -4 (x + 2) \\ y - 3 &= -4x - 8 \\ y &= -4x -5\end{aligned}[/tex]
In conclusion, the perpendicular line that passes through the point (-2, 3) is given by:
[tex]\displaystyle y = -4x - 5[/tex]
how to find standard form given 2 points
9514 1404 393
Answer:
(y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)
Step-by-step explanation:
The standard form equation of a line is of the form ...
ax +by = c
where a, b, c are mutually prime integers. The leading coefficient must be positive.
__
The standard form equation of a line can be found for the two points (x1, y1) and (x2, y2) using the formula ...
(y2 -y1)x -(x2 -x1)y = (y2 -y1)(x1) -(x2 -x1)(y1)
Using this equation, you must choose y2>y1. If y2=y1, you must choose x1>x2.
You will need to eliminate any fractions by multiplying the equation by an appropriate number. Once you have the numbers figured out, you need to factor out any common factors from the coefficients and the constant, so they are all mutually prime.

The main rotor of a helicopter is spinning at a constant rate. The rotor makes 80 revolutions every 12 seconds. At what rate, in revolutions per minute, is the rotor spinning?
Answer:
B/16
Step-by-step explanation:
if the rotor is spinning 80 reveloutions every 12 seconds and, a minute is 60 seconds
12 divided by 60 = 0.2
0.2 times 80 = 16.

find the solutions of the following equation. b^2 = 16/121 choose all answers that apply:
a. b= 2/7
b. b= - 2/7
c. b= 4/11
d. b= -4/11
e. none of the above
tysm <3
Answer:
c. b= 4/11
d. b= -4/11
Step-by-step explanation:
b^2 = 16/121
Take the square root of each side
sqrt(b^2) =± sqrt(16/121)
b = ±4/11
b² = -16/121
16 is 4² and 121 is 11²
b² = -4²/11²
b² = -(4/11)²
When exponents are common they are eliminated. Here, 2 is common
b = ±4/11
Hence, the answer is ±4/11OPTION c and d IS CORRECT

In this figure QR = XY ?
write the reason and find the pairs of matching angles.
Answer:
Yes
Step-by-step explanation:
I think you just rotate the triangle...
But since angle P and angle Z are the same, they fix the position the rays will go and since ZY=PQ=6cm and ZX=RP=4cm, they are the same triangle so QR=XY.
Pairs of matching angles would be angle R= angle X and angle Q = angle Y

Passes through (3,4) and is parallel to the line containing (3,5) and (0,2). Write answer in slope intercept form.
Answer:
should be 0
Step-by-step explanation:
Find the equation of the line passes through ( -3, 4) and parallel to the line 2y-4x + 2 = 0
Answer:
[tex]y = x + 1[/tex]
Step-by-step explanation:
We want to determine the equation of the line that passes through the point (3, 4) and is parallel to the line containing the points (3, 5) and (0, 2).
Recall that parallel lines have equivalent slopes.
Hence, first find the slope of the line containing the points (3, 5) and (0, 2):
[tex]\displaystyle m = \frac{\Delta y }{\Delta x} = \frac{(2)-(5)}{(0)-(3)} = \frac{-3}{-3} = 1[/tex]
Therefore, the slope of our new line must also be 1.
We are given that it passes through the point (3, 4). Since we are given a slope and a point, we can consider using point-slope form:
[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]
Substitute:
[tex]\displaystyle y - (4) = (1)(x - (3))[/tex]
Simplify:
[tex]y - 4 = x - 3[/tex]
And add. Hence, our equation in slope-intercept form is:
[tex]y = x + 1[/tex]
In conclusion, the line that passes through the point (3, 4) and is parallel to the line containing the two points (3, 5) and (0, 2) is:
[tex]y = x + 1[/tex]

The sun of three numbers is 40. The second number is 6 more than the first. The third number is 1 less than 5 times the first. Find all three numbers.
Answer:
first n = 5
sec n = 11
third n = 24
Step-by-step explanation:
40-6+1 = 35
35/7 = 5
1st no = 5
2nd no = first + 6
= 5+6
= 11
3rd no = 5(first) - 1
= 5(5) - 1
= 25-1
= 24
double check total = 1st + 2nd + 3rd
= 5 + 11 + 24
= 40

rachel states that -5.5 is an integer because it is negative. is she correct? why or why not?
Answer:
no
Step-by-step explanation:
-5.5=-55/10=-11/2
-11/2 is not an integer because it is not a whole number. even if it is negative, as long as it is in fraction form it is not an integer. therefore rachel is not correct

-5x-y=12
x+y=4
-6x+9y=11
Answer:
1. x = -12+y / 5 , y = -12-5x
2. x = 4 - y , y = 4 - x
3. x = -11 - 9y / 6 , y = 11 + 6x / 9
( for the numbers in fractions such as the x value for #1 and x & y value for #3, put the negative sign in front of the fraction, not the number okay? )
Step-by-step explanation:
-5x - y = 12---> -5x - y = 12 -5x - y = 12
= -5x - y = 12 = +5x +5x
+y +y ---------------------
--------------------- -y = 12 + 5x
-5x = 12 + y /-1 /-1
/-5 /-5 ----------------------
--------------------- y = -12-5x
x = -12+y / 5
-------------------------------------------------------------------------------------------
x + y = 4---> x + y = 4 x + y = 4
= -y -y = -x -x
--------------------- ----------------
x = 4 - y y = 4 - x
--------------------------------------------------------------------------------------------
-6x + 9y = 11-----> -6x + 9y = 11 -6x + 9y = 11
= -9y -9y = +6x +6x
------------------------------ ------------------------
-6x = 11 - 9y 9y = 11 + 6x
/-6 /-6 /9 /9
------------------------------- --------------------------
x = -11 - 9y / 6 y = 11 + 6x / 9
