Answer:
3.1415×10⁶
Step-by-step explanation:
Move the decimal point one digit at a time until it is after the first digit. Count the number of times the decimal point moved.
In this case, we move the decimal point 6 places to the left. So the scientific notation is:
3.1415×10⁶
Could someone factor this and explain how they did it? 0= x squared -x -6
Answer:
full answer below
Step-by-step explanation:
x^2 - x - 6 = 0
<=> x^2 - 3x + 2x - 6 = 0
<=> x(x-3) + 2(x-3) = 0
<=> (x-3)(x+2) = 0
<=> x= 3 or x = 2
If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that the first will be a triangle and the second will be a square?
Answer:
[tex]P(T\ n\ S) = \frac{1}{14}[/tex]
Step-by-step explanation:
*Missing Part of the Question*
4 stars
5 triangles
3 circles
3 squares
Required
Determine the probability of triangle being first then square being second
[tex]Total = 4 + 5 + 3 + 3[/tex]
[tex]Total = 15[/tex]
Represent the triangle with T and square with S
So, we're solving for P(T n S)
[tex]P(T\ n\ S) = P(T) * P(S)[/tex]
Solving for P(T)
[tex]P(T) = \frac{n(T)}{Total}[/tex]
[tex]P(T) = \frac{5}{15}[/tex]
Solving for P(S)
The question implies a probability without replacement;
Hence Total has now been reduced by 1
Total = 14
[tex]P(S) = \frac{n(S)}{Total}[/tex]
[tex]P(S) = \frac{3}{14}[/tex]
Recall that
[tex]P(T\ n\ S) = P(T) * P(S)[/tex]
[tex]P(T\ n\ S) = \frac{5}{15} * \frac{3}{14}[/tex]
[tex]P(T\ n\ S) = \frac{15}{15 * 14}[/tex]
[tex]P(T\ n\ S) = \frac{1}{14}[/tex]
Hence, the required probability is
[tex]P(T\ n\ S) = \frac{1}{14}[/tex]

What did I do wrong, it says I'm wrong
Answer:
This is not a function.
Step-by-step explanation:
Note, that set A contains 3 elements that only map to 2 elements in set B. A function would require that each element of set A to match to only one element of set B.
Since set B contains an element with no mapping to an element in set A, this does not represent a function.
How do I solve 4x-5=7+4y for y
Answer: Y= x-3
Step-by-step explanation:
Subtract 7 from both sides.
4x-5-7=4y
Simplify 4x-5-7 to 4x-12
4x-12=4y
Divide both sides by 4
4x-12/4 = y
Factor out the common term 4
4(x-3)/4 = y
Cancel 4
x-3=y
Switch sides
y=x-3

Answer:
y=-3+x
Step-by-step explanation:
a plane decides to travel along AB towards the North with a velocity of V.
Prove that the time taken to reach the destination due to the strong winds blowing from the north to east at an angle of alpha is
[tex] \frac{a}{ {v}^{2} - {w}^{2} } ( \sqrt{ {v}^{2} - {w}^{2} \ { \sin \ }^{2} \alpha } + w \cos( \alpha ) [/tex]
[using relative velocity /\ ]
Step-by-step explanation:
The wind has a speed of w and a direction α with the vertical. The x component of that speed is w sin α. The y component is -w cos α.
In order to stay on the north trajectory AB, the plane must have a horizontal speed of -w sin α. The plane's speed is v, so using Pythagorean theorem, the y component of the plane's speed is:
v² = (-w sin α)² + vᵧ²
v² = w² sin²α + vᵧ²
vᵧ = √(v² − w² sin²α)
The total vertical speed is therefore √(v² − w² sin²α) − w cos α.
If a is the length of AB, then the time is:
t = a / [√(v² − w² sin²α) − w cos α]
To rationalize the denominator, we multiply by the conjugate.
t = a / [√(v² − w² sin²α) − w cos α] × [√(v² − w² sin²α) + w cos α] / [√(v² − w² sin²α) + w cos α]
t = a [√(v² − w² sin²α) + w cos α] / (v² − w² sin²α − w² cos²α)
t = a [√(v² − w² sin²α) + w cos α] / (v² − w²)

The surface area of the given right cylinder is 252π square units. Therefore, option D is the correct answer.
What is total surface area of cylinder?The surface area of a cylinder refers to the total area that the cylinder's curved surface and circular bases cover. The total surface area of the cylinder includes the area of the 2 bases of the cylinder (each of which is in the shape of a circle) and the area of the curved surface.
Given that, the radius of a cylinder is 6 units and the height of a cylinder is 15 units.
We know that, the total surface area of a cylinder is 2πr(r + h).
Now, the surface area = 2×π×6(6+15)
= 2×π×6×21
= 252π square units
Therefore, option D is the correct answer.

Do the vertical function test
To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Answer:
[tex] m\angle XVW = 100\degree[/tex]
Step-by-step explanation:
In the first figure, FP is the bisector of [tex] \angle DFE[/tex]
[tex] \therefore m\angle 1 = m\angle 2\\
\therefore 44x + 1 = 46x - 1\\
\therefore 1 + 1 = 46x - 44x\\
\therefore 2 = 2x\\
\therefore \frac{2}{2} = x \\
\huge \red {\boxed {\therefore x = 1}} [/tex]
In the second figure, VP is the bisector of [tex] \angle XVW[/tex]
[tex] \therefore m\angle 1 = m\angle 2\\
\therefore 12x + 2 = 11x +6\\
\therefore 12x - 11x = 6 - 2\\
\therefore x = 4\\
\because m\angle XVW = m\angle1 + m\angle 2\\
\therefore m\angle XVW = 12x + 2 + 11x +6\\
\therefore m\angle XVW = 23x + 8\\
\therefore m\angle XVW = 23\times 4+ 8\\
\therefore m\angle XVW = 92+ 8\\
\huge \purple {\boxed {\therefore m\angle XVW = 100\degree}} \\

On average I sleep 7 hours and 45 minutes each day. Therefore, during one year I sleep for 7.45 x 365 = 2719.25 hours. Why is this calculation incorrect? And what is the correct answer?
Answer:
2830.6875 hours of sleep per year (7.45 should be 7.75)
Step-by-step explanation:
To find your average sleep per year, you need to covert avg hours per day, to days per year.
Note that 45 minutes is not equivalent to .45 hours, but actually .75 hours since there are only 60 minutes in an hour. ( 45 / 60 == .75 )
Simply, the amount of days per year is 365.25 (to account for leap years).
So perform this calculation:
(7.75 hrs / day ) * ( 365.25 days / year ) == 2830.6875 hrs / year
Meaning, on average you get 2830.6875 hours of sleep per year.

On Monday, a restaurant made $545 by selling 110 hamburgers. If they sold 53 hamburgers on Tuesday. How much money did they make? (Round your answer) *
Answer: $263
Step-by-step explanation:
From the question, we are informed that Monday, a restaurant made $545 by selling 110 hamburgers. This means that one hamburger costs:
= $545/110
= $4.955
Therefore, 53 hamburgers will cost:
= 53 × $4.955
= $262.62
= $263 approximately
use the formula for the area of a trapezoid A=h(b1+b2/2), were area is A b1 and b2 are the length of the base and h is the hight of 15yd. and the bases of 14yd.and 26yd
Answer: 300 yards
Step-by-step explanation:
Since b1 is equal to 14 yds and b2 is equal to 26 yds we can plug that into the equation below (in the image).
b1 + b2 = 14 + 26 = 40 yards
Now that we have found (b1 + b2), you can multiply that by h (the height of the trapezoid) which is 15, so we get 40 x 15 = 600.
In a lot of area equations, you will have to divide by two like in the trapezoid equation. Divide our number (600) by 2, so we get 600 ÷ 2 = 300.
300 yds is your final answer.

Which represents where f(x) = g(x)?
•f(4) = g(4) and f(0) = g(0)
•f(-4) = g(-4) and f(0) = g(0)
•f(4) = 9(-2) and f(4) = g(4)
•f(0) = g(-4) and f(4) = g(-2)
Answer:
Option (1)
Step-by-step explanation:
Two functions 'f' and 'g' have been graphed in the picture attached.
Both the functions will be equal at the points where the values of these functions are equal.
Those points are the point of intersection of both the functions on the given graph.
At x = -4,
f(-4) = g(-4) = 4
At x = 0,
f(0) = g(0) = 4
Therefore, Option (1) will be the answer.

Which of the numbers shown are
rational?
I.
TT
II. ✓49
III. 0.287
IV. ✓9/16
V.25
F I only
G II and III only
HII, III and IV only
J II, III, IV and V only
Answer:
The correct option is J.II, III, IV and V only.
Step-by-step explanation:
A rational number are those numbers that can shown in a p/q form or as the ratio of two numbers.
The numbers that cannot be shown as the ratio of two numbers are known as irrational.
Consider each number at a time:
[tex]\sqrt{49} =7\equiv 7:1[/tex]
[tex]0.287=\frac{287}{1000}[/tex]
[tex]\sqrt{\frac{9}{16}}=\frac{3}{4}\equiv 3:4[/tex]
[tex]25\equiv 25:1[/tex]
Thus, the numbers that are rational are II, III, IV and V.
The correct option is J.
