jnj
Answer:
I'm pretty sure it's 5
Step-by-step explanation:
It's 5 if: (please confirm before you answer it--the picture is blurry and it's hard to tell).
The line appears to intersect the origin (0,0) and (2.5,12.5).
Slope is rise over run, so if you take the difference in y value and divide it by the difference in x value, you get the slope.
How many numbers x between 1 and 100 (inclusive) have the property that x2+x3 is a perfect square?
(Please help. I'm suffering)
=========================================================
Explanation:
Factor the given expression
x^2+x^3
x^2*1+x^2*x
x^2(1+x)
x^2(x+1)
We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.
In short, we don't need to worry about the x^2 portion.
--------------------
The only thing of importance is the x+1 factor.
The x+1 must be a perfect square so that the original expression is as well.
Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}
If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".
Subtract 1 from each item to end up with this modified set
{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}
--------------------
Every item mentioned in that second set will make x^2+x^3 to be a perfect square.
For example, let's pick x = 15
x^2(x+1) = 15^2*(15+1)
x^2(x+1) = 15^2*16
x^2(x+1) = 15^2*4^2
x^2(x+1) = (15*4)^2
x^2(x+1) = 60^2
This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.
There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.
--------------------
To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.
What is 11 1/20 as a decimal?
11,05
Step-by-step explanation:
11 1/20
= (11 × 20 + 1)/20
= (220 + 1)/20
= 221/20 → times 5
= 1105/100
= 11,05
Answer:
11.05
Step-by-step explanation:
To convert a fraction to a decimal, multiply the fraction by [tex]\frac{x}{x}[/tex], x being the number that will multiply with the denominator to equal 100.
In this case, the value of x would be 5 because 20 × 5 = 100.
Now, multiply [tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex]:
[tex]\frac{1}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{5}{100}[/tex]
5 hundredths is equal to 0.05, so 11[tex]\frac{1}{20}[/tex] = 11.05.

Which equation represents a line that passes through (5, 1) and has a slope of 1/2?
Oy-5= 1/2(x-1)
oy- į = 5(x-1)
oy-1 = 1/2(x–5)
oy-1 = 5(x-1/2)
Answer:
C. y - 1 = 1/2(x - 5)Step-by-step explanation:
Use the point- slope form:
y - y₁ = m(x - x₁)Substitute know values:
y - 1 = 1/2(x - 5)The matching choice is C
The correct equation which represents a line that passes through (5, 1) and has a slope of 1/2 is,
y - 1 = 1/2(x - 5)
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
A equation of a line that passes through (5, 1) and has a slope of 1/2.
Now, Use the point- slope form:
⇒ y - y₁ = m(x - x₁)
Hence, Substitute all the values:
y - y₁ = m(x - x₁)
y - 1 = 1/2(x - 5)
Thus, The correct equation which represents a line that passes through (5, 1) and has a slope of 1/2 is,
y - 1 = 1/2(x - 5)

If we rewrite each term of the sequence to a common denominator then it makes it easier to see the pattern:
³/₂ , ²/₃ , ⁻¹/₆, -1 , ___
⁹/₆ , ⁴/₆ , ⁻¹/₆ , ⁻⁶/₆ , ___
This makes the pattern Xₙ = ⁹/₆ - ⁵⁽ⁿ⁻¹⁾/₆

I need help for all of them. I don’t understand how to do anything of them and i’m really confused
Answer:
steps below
Step-by-step explanation:
1) f(x) = (-3ax⁴ + ax² +x) / (2x⁴ + x³ - ax² + 8x) ... degree of the denominator = degree of the numerator (-3a) / 2 = 5 / 4
-12a = 10
a = - 5/6
2) 3-n > n+ 10 ... degree of the denominator < degree of the numerator
2n < -7
n < - 3.5
The largest inter value is -4
3) f(x) = (x²+3x-4) / (2x²+7x-10)
f(2) = (2²+3*2-4) / (2*2²+7*2-10) = 6 / 12 = 1/2
x->∞ : divide x² both numerator and denominator, any number/ x -> 0
f(x) = (1 + 3/x - 4/x²) / (2 + 7/x - 10/x) = (1 + 0 - 0) / (2 + 0 - 0) = 1/2
[tex]\lim_{x \to \infty} f(x) = f(2)[/tex] = 1/2

Victor's solution to an equation is shown below. Which property of real numbers did Victor use for Step 3? A. Associative Property of Multiplication B. Addition Property of Equality C. Subtraction Property of Equality D. Commutative Property of Multiplication
Answer:
can't see the equation sorry
Answer:
Subtraction Property of Equality
Step-by-step explanation:
Victor solved this inequality as shown:
Given: 6+3(x+5) = 36
Step 1: 6+3x+15 = 36
Step 2: 3x+21= 36
Step 3: 3x = 15
Step 4: 3x=15
What property justifies the work between step 3, I'm guessing its this question if not message me.
from step 2 to 3 we must use Subtraction Property of Equality since
3x+21 = 36 must subtract 21 both sides
then u get 3x=15

Your answer would be 154*. Reason being, if there are two parallel lines and a line running through them, you will only have 2 types of angles. The labeled 154* tells us that the angle to its right would be 26 degrees. Making line m = to 180 degrees at that angle. Then if you did the same thing with line t, you would get angle x to be equal to 154 degrees.
It is complicated like that, or as simple as just taking the 154 and saying that x has the same angle. Due to the fact that both angles are adjacent, they are the same.

What is the perimeter of a rectangle with length 15cm and width 4cm?
Show your work.
A. 38
B. 60
C. 239
D. 23
Answer:
A, 38cm
Step-by-step explanation:
since u have to take 15cm (the length) then multiply by 2 to take both the sides of the rectangle
then you have to take the width 2 times to take the perimeter and add it up. so 15x2 and 4x2 added is 38. there!

Although the actual amount varies by season and time of day, the average volume of water that flows over the falls each second is 3.2 x 10^5 gallons. How much water flows over the falls in an hour? Write the result in scientific notation. (Hint: 1 hour equals 3600 seconds)
Answer:
1.152 x 10^9 gal/hr
Step-by-step explanation:
Given:
3.2 x 10^5 gal / 1 sec
1 hr = 3600 s
Convert:
[tex]\frac{3.2 x 10^5 gal}{1 sec} * \frac{3600 sec}{1 hr}[/tex]
