Answer:
A.
Step-by-step explanation:
On graph A, all 4 points (G, P, R, and S) are all in the correct order. Options B and D are easy to eliminate because we know that none of the nests are actually at the center.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let me know if you have any questions! Spread the love.
Answer:
A.
Step-by-step explanation:
Options A and B are the only number lines with the blue point at the right spot (You can see it is 1/2 mile away so it goes in the middle of 1 and 2). Between these 2 only number line A has the red dot in the right spot (it belongs at -0.25 which is 1 spot left of the center 0).
solve for n 50 points
a=p(1+r/n)^rn
Answer:
[tex]n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }[/tex]
Step-by-step explanation:
[tex]a=p(1+\frac{r}{n} )^{nt}[/tex]
[tex]\frac{a}{p} =(1+\frac{r}{n} )^{nt}[/tex]
[tex]\sqrt[nt]{\frac{a}{p}} =(1+\frac{r}{n} )[/tex]
[tex]\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )[/tex]
[tex]n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }[/tex]

Which statement shows how the product of (x 3)2 demonstrates the closure property of multiplication? x2 9 may or may not be a polynomial x2 6x 9 may or may not be a polynomial x2 9 is a polynomial x2 6x 9 is a polynomial.
The product of (x + 3)² demonstrates the closure property of multiplication. [tex]\rm x^{2} + 6x + 9[/tex] is a polynomial. Option D is correct.
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
What is the closure property of multiplication?A set is closed under an operation when we do that operation on the member of the set and we always get a set member.
Given
An expression is (x + 3)²
On simplifying, we have
[tex]\rm (x + 3)(x + 3)\\\\x (x + 3) + 3 (x + 3)\\\\x^{2} +3x +3x +3^2\\\\x^{2} +6x + 9[/tex]
Thus, [tex]\rm x^{2} + 6x + 9[/tex] is a polynomial.

Find 25% of 116 I don't know the answer
Answer:
29
Step-by-step explanation:
Let's set up an equation...
25%*116=x
We can first convert 25% to a fraction. We can convert any percentage into a fraction by simply putting the number over 100...
[tex]\frac{25}{100}*116=x[/tex]
We can simplify 25/100 by dividing the fraction by 25/25. Note we can only do this because 25/25 is equivalent to 1, therefore meaning we are dividing the fraction by 1.
[tex]\frac{1}{4}*116=x\\\frac{116}{4}=x\\x=29[/tex]

Let x = -2
(( -2)^2 -8)/ ( -2+6)
(4-8)/(-2+6)

-1
Answer:
( -1 )
Step-by-step explanation:
Given that,
[tex]\frac{(x^{2}-8) }{(x+6)}[/tex]
Also given that,
x = -2
So, to solve the above expression, you have to replace x with ( - 2 )
Let us solve.

Answer:
2/3
Step-by-step explanation:
Probability of choosing an eclair = 1/15
This means that there is 1 eclair in every 15 sweets.
As there are 3 eclairs, there are 3 x 15 = 45 sweets in total.
Now we can write an expression for the total number of sweets and solve for x:
Total number of sweets = 3 + (2x + 6) + x = 45
⇒ 3x + 9 = 45
⇒ 3x = 45 - 9
⇒ 3x = 36
⇒ x = 36 ÷ 3
⇒ x = 12
Now we have found x, we can determine the number of humbugs in the jar by substituting x = 12 into 2x + 6:
(2 x 12) + 6 = 30
So the probability the sweet is a humbug is 30 / 45 = 2/3
Please help I tried doing this. It’s due tomorrow please help! Give me an explanation please by the way!

f (x) = 3x - 5 g (x) =2^x Find f^-1 (x)
Answer:
f^-1(x) = (x +5)/3
also = 1/3 x + 5/3
Step-by-step explanation:
Just to be clear, the ^-1 has nothing to do with negative exponents. It just unfortunately looks the same as a negative exponent.
Anyway, there's three basic steps. First write y instead of f(x). Then switch the x and y. Then solve for y.
f(x) = 3x - 5
write y in place of f(x).
y = 3x - 5
SWITCH x and y.
x = 3y - 5
SOLVE for y.
-3y + x = -5
-3y = -x - 5
y = (-x - 5)/-3
y = (x + 5)/3
OR
y = (1/3)x + 5/3
f^-1(x) = 1/3 x + 5/3

simply knowing the formula will lead you to the answer easily.
formula to find the volume of a prism:
v = bh, where b = base area and h = height.
here, in the picture given, the :
h of the prism = 6m
base area = length * width
b = 8 cm × 7 cm
b = 56 cm²
thus, using v = bh,
v = 56 × 6

Like term's coefficient are added in addition of algebraic terms. The simplified form of the given expression is [tex]x^3 + 8x^2 + 13[/tex]
What are like terms?Those terms which have same variables raised with same power.
For example, [tex]5t^3[/tex] and [tex]6t^3[/tex] are like terms since variable is same, and it is raised to same power 3.
For example [tex]x^3[/tex] and [tex]3x^4[/tex] are not like terms as the variables are same but powers aren't same.
What are coefficients?Constants who are in multiplication with variables are called coefficients of those variables.
When can we add or subtract terms of polynomial by their coefficient's addition or subtraction?Suppose we have
[tex]5x^2 + 6y[/tex]
Since those terms are not like terms, their coefficient won't be add and the expression we've got right now, is its simplest form and cannot be reduced more.
If we have, suppose,
[tex]4x + 5x^2 + 2x[/tex]
then we see that [tex]4x[/tex] and [tex]2x[/tex] are like terms, their coefficient can be added and thus, the simplified form would be
[tex](4+2)x + 5x^2 = 6x + 5x^2[/tex]
For the given case, the considered expression is simplified as:
[tex]= > (6x^2 - 3 + 5x^3) - (4x^3 - 2x^2 - 16)\\= 6x^2 - 3 + 5x^3 -4x^3 + 2x^2 + 16\\ = 5x^3 - 4x^3 + 6x^2 + 2x^2 - 3 + 16\\= (5-4)x^3 + (6+2)x^2 + 13\\= 1.x^3 + 8x^2 + 13 \\= x^3 + 8x^2 + 13[/tex]
(variables with 1 as coefficient is not written explicitly as 1 is factor of all measurements).
Sign multiply by
[tex]-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]
where -ve, +ve are sign of operands and result.
Thus, the simplified form of the given expression is [tex]x^3 + 8x^2 + 13[/tex]

Find a polynomial that represents the area of the triangle in inches.
Answer:
(3x²-3.5x+1)in²
Step-by-step explanation:
area of a triangle = ½(base × height)
= ½(2x-1)(3x-2)
= ½(6x²-4x-3x+2)
= ½(6x²-7x+2)
= 3x²-3.5x+1
A polynomial that represents the area of the triangle is (3x²-3.5x+1)in²
