i reallyyy need help ! a p e x
Answer:
D
Step-by-step explanation:
Because the closed dot is connected to the one less than 1, we know that one of the equation is less than or equal to 1. So this eliminates A.
B makes no sense because it shows two equations for when x < 1. So this one can be ruled out immediately.
We also notice the shape of the functions, the one on the bottom looks like a cube, you can make out the beginning of the chair shape. So the one that is less than or equal to 1 is the cubic function. Which eliminates C.
This leaves D and you can plug in values of x and y to confirm this is correct.
Answer:
Step-by-step explanation: First you look at the left side of the graph. You can tell by the shape that it is an x^3 function. also the filled in circle means inclusive. so we know that when x <= (whatever number). It is impossible to tell for sure with this graph if it is on 1. for the first part. the only answer that has less then or equal to is the last one, D. So the answer is D. You can look at the right side that it is open circle. So we know it is >. So we can see the bottom part of D has that as well
Harry reads that a particular element has an atom with a mass of 0.000000000012 grams. What is the weight of the atom expressed in scientific notation?
A.
1.2 × 10-9 grams
B.
1.2 × 10-11 grams
C.
1.2 × 1011 grams
D.
1.2 × 1012 grams
Answer:
Since this number is small we know that the exponent will be negative.
In scientific notation the decimal must be between the first two NON zero numbers. So move the decimal and count how many positions it was moved.

Step-by-step explanation:
Angle UQN = Angle QNM, in alternate interior angle relation so Angle QNM will be x.Now we know that the angles inside a triangle sum up to give 180⁰,that is x+x+42⁰=180⁰2x+42⁰=180⁰
2x=180⁰- 42⁰
2x= 138⁰
x= 138⁰/2
x= 69⁰
Which of the following is equivalent to (x+5)(2x^2 +8)?
A. (x+5)(2x^2)• (X+5)(8)
B. (x+5)(2x^2)+(x+5)(8)
C. (x+5)(2x)+(x+5)(8)
D. (x+5)(2x)• (x+5)(8)
Answer:
(x+5)(2x^2 +8)
Multiply (x+5) in both sides
(x+5)(2x^2) × (x+5)(8)

Evaluate this expression (3+4)-4/42+3(4+2)/3
Answer:
Step-by-step explanation:
Use PEDMAS
(3 + 4) - 4/42 + 3(4 +2)/3 = 7 - [tex]\frac{4}{42}[/tex] + 3 * [tex]\frac{6}{3}[/tex] {Inside parenthesis}
= 7 - [tex]\frac{2}{21}[/tex] + 6 {Division}
= 13 - [tex]\frac{2}{21}[/tex]
[tex]=\frac{13*21}{1*21}-\frac{2}{21}\\\\=\frac{273}{21}-\frac{2}{21}\\\\=\frac{271}{21}[/tex]

QUICK! WHAT IS THIS ANSWER?
Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
a)we want to expand the following expression:
[tex] \displaystyle - \frac{1}{4} ( - 8x + 12y)[/tex]
well to do so we consider distributive property thus distribute:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)[/tex]
reduce fraction which yields:
[tex] \displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)[/tex]
simplify Parentheses:
[tex] \displaystyle \boxed{ 2x - 3y}[/tex]
b)in the expression there's a common factor of 4 therefore factor it out:
[tex] \displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}[/tex]

Is (5, 0) a solution to the equation y = x + 5?
Guys I need help
Answer:
no
Step-by-step explanation:
substitute the x- coordinate 5 into the equation and if the result is equal to the y- coordinate 0 then it is a solution
y = 5 + 5 = 10 ≠ 0
Then (5, 0 ) is not a solution to the equation

If the two legs of a right triangle are 15 and 20, how long is the hypotenuse?
Answer:
25
Step-by-step explanation:
To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:
15^2 + 20^2 = c^2
225 + 400 = c^2
625 = c^2
c = 25
This means the hypotenuse is 25.
Two-Fifths of a number is 48. What is 3/4 of the SAME number?
Need help urgently
Answer:
[see below]
Step-by-step explanation:
"Two-Fifths of a number is 48."
(2/5)n = 48
((2/5n)(5/2) = 48 *(5/2)
n = 120
------------------------------------
120 * (3/4) = 90

Step-by-step explanation:
A biased 3-coloured spinner was spun 240 times. It landed on Red n times, on Orange 3n times and on Yellow 8n times.
If you spin this spinner 1000 times, how many times do you expect it to land on Red?
(Hint: Find n first)
Answer:
83 times.
Step-by-step explanation:
n + 3n + 8n = 240
12n = 240
n = 20.
So we have 20 reds in 240 spins
So by proportion the number expected in 1000 spins
= 20 * 1000/240
= 1000/12
= 83 1/3
So its 83 reds.

Cho hình thang ABCD(AB//CD) có AB=40cm CD=80cm BC =50cm AD=30cm cmr ABCD là hình thang vuông
From A draw AG // BC cuts CD at WO
We have: Trapezoid ABCD (assumption)
⇒ AB // CD
⇒ AB // GC (because G ∈ CD)
Considering quadrilateral ABCG, there are:
AB // GC (proven above)
AG // BC (assumption)
⇒ Quadrilateral ABCG is a parallelogram
⇒ AB = GC = 40 cm
AG = BC = 50 cm
We have: DG = CD - GC (because G ∈ CD)
DG = 80 - 40
⇒ DG = 40(cm)
Considering ΔAGD, there are:
AG2=AD2+DG2AG2=AD2+DG2
502=302+402⇒502=302+402
⇒502=900+1600⇒502=900+1600
502=2500⇒502=2500
⇒502=502⇒502=502
⇒ AGD square at D
⇒ Trapezoid ABCD is a square trapezoid
