Answer:
No, it is not in scientific notation. The first factor is not greater than or equal to 1.
Step-by-step explanation:
Scientific notation is a method of writing numbers as the product of two factors where the first factor is a number whose absolute value is greater than or equal to 1 but less than 10.
Answer:
last option
Step-by-step explanation:
In scientific notation the number being multiplied by the power of 10 has to be in between 1 and 10, and since 0.11 doesn't satisfy this the answer is it is not in scientific notation because the first factor is not greater than or equal to 1.

Which of the following are solutions to the equation below?
Check all that apply.
6x2 - 2x + 36 = 5x2 + 10x
O A. 18
B. 4
C. 6
D. -6
O E. -3
F. -4
Answer:
B. 4
Step-by-step explanation:
Rearrange the equation so that is in the form (ax² + bx + c = 0).
6x² - 3x + 36 = 5x² + 10x
x² - 3x + 36 = 10x
x² - 13x + 36 = 0
Now, factor the equation and solve for x.
x² - 13x + 36 = 0
(x - 4)(x - 9) = 0
x - 4 = 0
x = 4
x - 9 = 0
x = 9
The solutions to the equation are 4 and 9. The correct answer choice is B.
Answer:
The answer B.4
Step-by-step explanation:
Arrange the equation so that is in the form
(ax² + bx + c = 0).
6x² - 3x + 36 = 5x² + 10x
x² - 3x + 36 = 10x
x² - 13x + 36 = 0
the equation and solve for x.
x² - 13x + 36 = 0
(x - 4)(x - 9) = 0
x - 4 = 0
x = 4
x - 9 = 0
x = 9

A scientist is running an experiment with
two species of bacteria that grow exponentially.
If species A doubles in population every
two days, species B doubles in population
every five days, and each species began the
experiment with a population of 50 bacteria,
what will the difference be between the
populations of the two species after ten days?
(A) 200
(B) 800
(C) 1,200
(D) 1,400
Answer:
D 1,400
Step-by-step explanation:
Species A doubles every 2 days and species B doubles every 5 days, so in 10 days, species A will double 10/2 = 5 times and species B will double 10/5=2 times. After 10 days from an initial population of 50 in each species, species A will have 50 x 2 ^5= 50 x 32 = 1,600 population while species B will have 50 x 2 ^2 = 200 population. Their difference is 1,600-200 = 1,400.

The triangle moved 6 units right and one unit up.
Complete each step in the following solution.
10x + 8 = 3(x – 2)
10x + 8 = 3x ___
7x = ___
x = -2
A: 10x + 8 = 3(x – 2)
10x + 8 = 3x – 6
7x = – 14
x = -2
Step 1 : Multiplying 3 with -2, we get -6
Step 2 : Subtract -6 and 8 , we get -14
Step 3 : We get x = -2
What is an equation?"An equation is a formula that expresses the equality of two expressions, by connecting them with the equal sign. Solving an equation containing variable consists of determining which values of the variables make the equality true."
Given equation
10x + 8 = 3(x – 2)
In this step by multiplying 3 with -2, we get -6
10x + 8 = 3x - 6
Subtract the variables
Subtract -6 and 8 , we get -14
7x = -6 - 8
7x = -14
Divide with 7 on both sides, we get
x = -2
Hence these are the following steps to get x = -2
Step 1 : Multiplying 3 with -2, we get -6
Step 2 : Subtract -6 and 8 , we get -14
Step 3 : We get x = -2

Solve for X (BRAINLIEST)
Answer:
x = 24
Step-by-step explanation:
The triangles are similar so we can use ratios to solve
x 6
------ = -----------
x+8 8
Using cross products
8x = 6*(x+8)
8x = 6x+48
Subtract 6x from each side
8x-6x = 48
2x = 48
Divide by 2
2x/2 = 48/2
x = 24
Answer:
x = 24
Step-by-step explanation:
Very similar to the previous problems of this type, these two triangles have a shared angle A and both have a right angle, prove AA similarity.
From there, we can set up a ratio:
(x+8)/x = 8/6
Multiply both sides by x:
x+8 = 8x/6
Multiply both sides by 6:
6x+48 = 8x
Move the 6x to the right:
48 = 2x
Divide both sides by 2:
x = 24
What is being constructed based on the markings in the following diagram?
Line AB with two points C and D on each side of the line; a circle is created with center C passing through point D, and the intersection of circle C with line AB creates points E and F such that point A is between points E and F and point F is between points A and B. Point G is not located on line AB and is on the same side as point D. A circle is created with center F and a radius of FG, and another circle is created with the same radius from point E. Points H and I are intersecting points of circles E and F, and a line is drawn through points H and I.
Inscribed regular hexagon
Inscribed equilateral triangle
Perpendicular line through a point off a line
Perpendicular line through a point on a line
Answer:
The correct option is;
Perpendicular line through a point off a line
Step-by-step explanation:
Based on the markings in the diagram, we have;
Marking points E and F along AB extended forms two points equidistant from the point C on the line AB
Construction of the line HI by using equal arc lengths from E and F creates two points equidistant from E and F on either side of the line AB such that HI passes through C forming a perpendicular bisector from C to AB.
Therefore, a perpendicular line has been constructed from the point C off the line AB to the line AB
Hence the correct option is the construction of a perpendicular line through a point off a line.

Solve the inequality for x. –8x + 16 > –72 A) x 7 D) x > 11
Answer:
x < 11
Step-by-step explanation:
–8x + 16 > –72
Let's transfer the components which do not contain x to the right side and change sign of these components
-8x > -72 - 16
Now, we simplify the right side
-8x > -88
We then multiply both sides by (-1/8) and change the greater symbol to smaller symbol
(-1/8)*(-8)x < (-1/8)*(-88)
Finally, we simplify both sides to solve this inequality
x < 11

Step-by-step explanation:
If there is a straight line and 1 angle is 90 degrees, the angle next to it is also 90 degrees.
Answer:

Step-by-step explanation:
Since x and 90° share the same straight line, they are supplementary, meaning they must add up to 180°. Hence x must be 180-90 = 90.
Let a and b be real numbers where a b 0. Which of the following functions could represent the graph below?
Answer:
C. f(x) = x4(x – a)(x – b)2
Step-by-step explanation:
just took the test on edge
A function which could represent the above graph is: C. f(x) = x⁴(x - a)(x - b)².
How to interpret the graph?In Mathematics, the nature of the intercept on a polynomial graph highlights the nature of its multiplicity. Also, the polynomial graph has no single zero (factor) but bounced off the x-axis at three (3) different locations.
This ultimately implies that, the polynomial graph has an even multiplicity at these three (3) points:
x⁴x - a(x - b)²In conclusion, a function which could represent the above graph is f(x) = x⁴(x - a)(x - b)².

When dividing complex numbers, why do you need to multiply the numerator and denominator by the complex conjugate of the denominator?
Answer:
Step-by-step explanation:
So that the denominator is a real number. I know that doesn't sound like a good reason, but it is the reason mostly by convention. You don't want complex i's floating all over the answer. There should be just one i.
Answer:
You have to multiply by the complex conjugate because the denominator has to be a real number. By multiplying the complex conjugate you can transform the denominator in to a real number.
