Answer:
4.18 × 10^ 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
I am assuming that number began with a decimal point.
Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes
4.18X10^(-5)

Four points are labeled on the number line. P. Q. R. S. Which point represents the value of the absolute value of negative 1 over 2?
Answer:
See Explanation
Step-by-step explanation:
Incomplete question, as the number line is not attached. However, the solution is as follows:
Let y be the absolute value of -1/2 So:
[tex]y = |-\frac{1}{2}|[/tex]
The absolute sign removes all negation. So:
[tex]y = \frac{1}{2}[/tex]
This means that the point at the label [tex]\frac{1}{2}[/tex] or [tex]0.5[/tex] is the solution to the question.
Take for instance, the attached image has point Q at [tex]\frac{1}{2}[/tex].
Hence, Q is the absolute value of -1/2

The midpoint is 300 because the distance from the 2 points is 100 so 300.
The sum of N terms of an arithmetic sequence with first term as 1 and common difference of 2 is 9801. Calculate the value of N.
Answer:
gngngngngngngngngngng
Answer:
n = 99
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 1 , d = 2 and [tex]S_{n}[/tex] = 9801 , then
[tex]\frac{n}{2}[/tex] [ (2 × 1) + 2(n - 1) ] = 9801 ( multiply both sides by 2 to clear the fraction )
n(2 + 2n - 2) = 19602
n(2n) = 19602
2n² = 19602 ( divide both sides by 2 )
n² = 9801 ( take the square root of both sides )
n = [tex]\sqrt{9801}[/tex] = 99
The number of terms summed is 99
degree of the polonomial 7x2yz2+6xy2z3-5x+8y
Answer:
degree of the polonomial : 6
Step-by-step explanation:
Identify the exponents on the variables in each term, and add them together to find the degree of each term.
7x²z²⇒4
6xy²z³⇒6
−5x⇒1
8y⇒1
The largest exponent is the degree of the polynomial.

Which product of prime polynomials is equivalent to 3x4 – 81x?
3x(x – 3)(x2 – 3x – 9)
3x(x – 3)(x2 + 3x + 9)
3x(x – 3)(x – 3)(x + 3)
3x(x – 3)(x + 3)(x + 3)
Given:
The expression is
[tex]3x^4-81x[/tex]
To find:
The product of prime polynomials which is equivalent to the given expression.
Solution:
We have,
[tex]3x^4-81x[/tex]
Taking out the common factors, we get
[tex]=3x(x^3-27)[/tex]
It can be written as
[tex]=3x(x^3-3^3)[/tex]
[tex]=3x(x-3)(x^2+3x+3^2)[/tex] [tex][\because a^3-b^3=(a-b)(a^2+ab+b^2)][/tex]
[tex]=3x(x-3)(x^2+3x+3^2)[/tex]
[tex]=3x(x-3)(x^2+3x+9)[/tex]
Therefore, the correct option is B.
Answer:
It's B

Simon has x sweets.
Yuen has 2 more sweets than Simon.
Giulia has 3 times as many sweets as Yuen.
Simon, Yuen and Giulia have a total of T sweets.
(a) Write down a formula for T in terms of x.
Give your formula in its simplest form.
Here is your answer!
= x + (x + 2) + 3(x + 2) = T
= (3x + 2) + (3x +6) = T
= 3x + 3x + 2 + 6 = T
= 6x + 8 = T

T = 5x + 8 is the formula for T expressed in terms of x.
What is inequality?A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics. Therefore, an imbalance leads to inequity.
Given, Simon has x sweets. Yuen has 2 more sweets than Simon. Giulia has 3 times as many sweets as Yuen. Simon, Yuen, and Giulia have a total of T sweets.
From the given Data,
Thus, in Total sweets, Simon has = x
Total sweets Yuen have = x + 2
Total sweets Giulia have = 3*(x + 2 )
Since the total sweets all three have is T
Hence, T = x + x +2 + 3(x + 2)
T = x + x + 2 + 3x + 6
T = 5x + 8
Therefore, The formula for T in terms of x is T = 5x + 8

What is the probability of drawing a queen or a heart from a standard deck of 52 cards?
Reminder: the four card families
Pleasee helpppppp!!
Answer:
4/13
Step-by-step explanation:
4 queens and 13 hearts
4/ 52 + 13/52 - 1/52
16/52
4/13
Answer:
Step-by-step explanation:
There are 13 hearts in 52 cards. C From above, P(Queen)=4/52 and P Heart=13/52, the queen of hearts is in both categories so we have to subtract 1/52 so we don't double count.
What is the equation of a line parallel to the line y = 4x - 5 with a y intercept of
3?*
What is the slope of a line perpendicular to the line whose equation is 4x−10y=404x−10y=40. Fully simplify your answer.
Answer:
[tex] - \frac{5}{2} [/tex]
Step-by-step explanation:
4x -10y= 40
Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.
10y= 4x -40
Divide both side by 10:
[tex]y = \frac{2}{5} x - 4[/tex]
The product of the gradients of perpendicular lines is -1.
⅖(gradient of line)= -1
Gradient of perpendicular line
[tex] = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} [/tex]
[tex] = - \frac{5}{2} [/tex]

If y varies directly as x and y = 5.5 when x = 11, find x when y = 3.5

7
Step-by-step explanation:
Let us say that [tex]y_{1}[/tex]= 5.5, [tex]x_{1}[/tex]= 11, and [tex]y_{2}[/tex] = 3.5.
[tex]\frac{y_{2}}{y_{1}} =\frac{x_{2}}{x_{1}}[/tex]

Which quadratic function has a vertex point of (3,5) and passes through the
point (-2,55)?
9514 1404 393
Answer:
f(x) = 2(x -3)² +5
Step-by-step explanation:
For vertex (h, k) and scale factor 'a', the vertex form is ...
f(x) = a(x -h)² +k
We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.
55 = a(-2 -3)² +5
50 = 25a . . . . . . . . subtract 5
a = 2 . . . . . . . . . . . divide by 25
So, the function is ...
f(x) = 2(x -3)² +5
__
In standard form, that will be ...
f(x) = 2x² -12x +23

Garth is building a square shaped frame for a mirror. The area of the mirror is 144 square inches. How long is each side of the frame, in inches?
Answer: 12 inches
Step-by-step explanation:
This is a square shaped mirror which means that it takes the shape of a square.
All sides on a square are equal and because the way the find the area of a square is to multiple the Length by the Width, you would be squaring the same number to find the area.
Length of each side = √area
= √144
= 12 inches
Find the value of y, and then find all angles, pls help quick
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angle.
146° is an exterior angle of the triangle, then
5y + 3 + 4y + 8 = 146
9y + 11 = 146 ( subtract 11 from both sides )
9y = 135 ( divide both sides by 9 )
y = 15
Then
∠ A = 5y + 3 = 5(15) + 3 = 75 + 3 = 78°
∠ B = 4y + 8 = 4(15) + 8 = 60 + 8 = 68°
∠ C = 180° - (78 + 68)° ← sum of angles in triangle = 180°
∠ C = 180° - 146° = 34°

Answer:
6/10
Step-by-step explanation:
6/10 is equal to 3/5 because you can multiply 3/5 times 2. So multiply the numerator(3) times 2, which is 6, then multiply the denominator(5) times 2 as well, which is 10.

Simplify the square root of:
√32
Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
factor the square root of 32
to get a total of 32, you do 4 times 4, which is 16
16 times 2 =32
16 is a perfect square so it's outside of the square root symbol, but you can't find the square root of 2 without it being irrational.
So,
final answer: 4[tex]\sqrt{2}[/tex]
