WRITE 0,000003 56 IN SCIENTIFIC NOTATION
Answer:
3.56X10^-6
Step-by-step explanation:
In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:
1. The numerical coefficient.
2. Number of times we move the decimal point. It will be the exponent with the base of 10.
3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.
Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

9. y + 7 = 2(x + 5)
in standard form
Answer:
y=2x+3
Step-by-step explanation:
1. y+7=2(x+5) (rewrite the problem)
2. y+7=2x+10 (distribute the 2)
3. y=2x+3 (subtract 7 from both sides; 10-7=3)

11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
Answer:
x = - 1
Step-by-step explanation:
Given
f(x) = x³ + x² + x + 1
If x = 1 is a factor then f(1) = 0
f(1) = 1³ + 1² + 1 + 1 = 4 ≠ 0 , thus x = 1 is not a zero
f(- 1) = (- 1)³ + (- 1)² + (- 1) + 1 = - 1 + 1 - 1 + 1 = 0
Thus x = - 1 is the only zero

-x-3y- 3z= 16
-6x+3y+2z=-27
4x+6y+4z=-22
I will give brainliest to whoever shows steps!
Answer:
Step-by-step explanation:
-x-3y-3z=16
x=-3y-3z-16
-6x+3y+2z=-27
6x=3y+2z+27
x=3/6 y + 2/6 z +27/6
x=1/2y+1/3z+9/2
4x+6y+4z=-22
4x=-6y-4z-22
x= -6/4y -4/4 z -22/4
x=-3/2y -z-11/2
Answer:
(x, y, z) = (2,-3,-3)
Step-by-step explanation: 4x+6y+4z = -22 Divide both sides by = 2x + 3y+2z= -11
To solve the system , rewrite it as two systems each consisting of two equations.
1) {-x-3y-3z = 16} {-6x+3y+2z = -27}
2) {-x-3y-3z=16} {2x+3y+2z=-11}
Solve the system of equations
1) -7x-z=-11
2)x-z=5
Write as a system of equations
{-7z-z=-11} {x-z=5}
Solve the system of equations
z = -3
x= 2
Substitute the given value of z, x into the equation : -x-3y-3z = 16
-2-3y-3x(-3)= 16
Solve for Y
y= -3
Due in 3 mins !! 3 questions Triangle ABC, is rotated 90° counter clockwise about the origin to make triangle A'B'C. Drag and drop the coordinates to describe the transformation !! ( picture!)
Answer:
A'=(3,-2) B'=(-1,-4) C'=(-5,-3)
Step-by-step explanation:
90 degrees counterclockwise uses (-y,x) so you just plug in the negative y value in the x spot and the x value in the y spot

Answer:
The coordinates of mage of L(5, 10) will be: (11, 3)
So, the 4th (last) option is correct.
Step-by-step explanation:
As we know that Translation means how much a point is moved to the left/right and up/down.
Given the translation maps the point J(1, 4) onto K(7, -3).As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).
Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)
so it means the translation basically implies that
(x, y) → (x + 6, y - 7)
Hence, the coordinate of the image of L(5, 10) can also be determined by
using the same rule.
(x, y) → (5 + 6, 10 - 7) = (11, 3)
Therefore, the coordinates of mage of L(5, 10) will be: (11, 3)
So, the 4th (last) option is correct.

Select all the correct graphs.
Choose the graphs that indicate equations with no solution.
Answer:
The first and last graph.
General Formulas and Concepts:
Algebra I
Solving systems of equations graphicallyStep-by-step explanation:
In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.
Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.
1. A set of weights includes a 5 lb barbell and 8 pairs of weight plates. Each pair, p,
weights 10 lbs. If x pair of weight plates are added to the barbell, the total weight of the
barbell in pounds can be represented by the function
f(x) = 10x + 5. What is a reasonable range of the function in this situation?
Answer:
5 <= y <= 85
Step-by-step explanation:
Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)
The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).
Using the function given, if you input 8 as the x value, you get
85 = 10(8) + 5
So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.

for each graph below, state wether it represents a function.
Answers:
Row 1: No, No, No
Row 2: Yes, Yes, Yes
===============================
Explanation:
Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.
So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.

17. Let f(x) = 2x2 + 5x + 6 and g(x) = 3x2 + 4x – 10.
a Find f(x) + g(x)
b. Find f(x) – g(x)
Step-by-step explanation:
f(x)+g(x)=(2x^2 + 5x +6) + (3x^2 +4x - 10)
Combine like terms
5x^2 + 9x -4
f(x)-g(x)=(2x^2 + 5x +6) - (3x^2 +4x - 10)
Distribute the negative
(2x^2 + 5x +6) + (-3x^2 -4x + 10)
Combine like terms
-x^2 +x +16

Dracula has 48 pieces of candy. He gave 1⁄3 of his candy to his friend and 25% of his candy to his cousin. How many pieces of candy does Dracula have left?
Please show your work.
Answer:
20
Step-by-step explanation:
1/3 of 48 is 16, and 25% of 48 is 12. 16 + 12 = 28.
48 - 28 = 20

For a United Way fund-raising dinner, a total of 245 tickets were sold. Adult tickets sold for $6.50, and child tickets sold for $3.00. If $1410.50 worth of tickets were sold, how many adult and child tickets were sold?
Answer:
Adults =193
children=52
Step-by-step explanation:
Step one:
let the number of tickets adults be x
and the number of tickets children be y
x+y=245--------1
6.5x+3y=1410.5---2
Step two:
solve the system of equation using substitution
x+y=245
x=245-y
put x=245-y in equation 2 we have
6.5(245-y)+3y=1410.5
1592.5-6.5y+3y=1410.5
-6y+3y=1410.5-1592.5
-3.5y=-182
y=182/3.5
y=52
put y=52 in x=245-y
x=245-52
x=193
Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).
Answer:
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus
y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)

Solve the compound interest problem. $3425 is invested at %7.5 compounded monthly for years. a. Find the overall amount. b. Find the compound interest.
Complete question :
Solve the compound interest problem. $3425 is invested at %7.5 compounded monthly for 2 years. a. Find the overall amount. b. Find the compound interest.
Answer:
$3977.425 ; $552.425
Step-by-step explanation:
Given that:
Principal (P) = $3425
Rate (r) = 7.5% = 0.075
Time(t) = 2 years
A = p(1 + r/n)^nt
r = rate
n = number of times compounded per year
t = time in years
A = final amount
A = 3425(1 + 0.075/12)^12*2
A = 3425(1 + 0.00625)^24
A = 3425(1.00625)^24
A = 3425(1.1612920)
A = $3977.4251
Hence, overall amount = $3977.425
Compound interest = $(3977.425 - 3425) = $552.425
