Answer:
Domain exists on all real values and it is expressed according to the notation:
(-∞, ∞)
Step-by-step explanation:
The domain of a function is the values of the input variables x that will make the function exist.
Given the function f(x)=-16x^2+400
Since the variable x is a perfect square, this means that the function f(x) will exists for all values of x. The domain is expressed as:
(-∞, ∞)

Given the graph below, identify the list that has each point correctly identified?
Answer:
The third option
Step-by-step explanation:
Looking at all of the points, we can tell that those are the correct coordinates for each of them.
Answer:
C
Step-by-step explanation:
A point (x, y) is just (the distance to the right of the y axis, the distance above the x axis). That means we have:
L = (1,2)
N = (5,-1)
M = (-3, -4)
... which makes C the right answer

If a rocket travels 35,200 miles in 2 hours, what is its speed?
If a rocket is launched from the surface of the Earth, it needs to reach a speed of at least 7.9 kilometers per second (4.9 miles per second) in order to reach space. This speed of 7.9 kilometers per second is known as the orbital velocity, it corresponds to more than 20 times the speed of sound.
HELO PLEASE WILL GIVE BRAINLIEST Which series of transformations will map the trapezoid onto itself?
reflection over the x-axis, then a rotation 180° counterclockwise about the origin
reflection over the y-axis, then a rotation 180° counterclockwise about the origin
o reflection over the line y = x, then a rotation 90° counterclockwise about the point (0, 2)
O reflection over the line y = 2, then a rotation 90° counterclockwise about the point (0, 2)
Answer:
Step-by-step explanation:
In order to map the trapezoid onto itself, reflect the trapezoid over the x-axis, then rotate trapezoid by 180° in counterclockwise about the origin.
For the image of a figure to overlap with itself, the amount by which the figure should be rotated is?For the image of a figure to overlap with itself, the figure should be rotated by 360°
We have a trapezoid as shown in the image.
In order to map the trapezoid onto itself -
Reflect the trapezoid over [x] axis.Now, rotate it counter - clockwise by 180 degreesTherefore, in order to map the trapezoid onto itself, reflect the trapezoid over the x-axis, then rotate trapezoid by 180° in counterclockwise about the origin.

what is the equation in slope intercept form of the line that passes through point (1,2) (3,4)
Answer:
y = 1x + 1
Step-by-step explanation:
Lucy has no more than $50 from her
birthday to spend. She plans to buy as
many pairs of earrings as she can. The
cost of each pair of earrings is $5. There
is also a single shipping charge of $2.
Write an inequality to represent Lucy's
situation.
Answer:
7-8
Step-by-step explanation:
You spent $173.20 buying three games at Best Buy along with a set of earpods that cost $37.00. If g is the cost of the game, and the equation representing the purchase is: 3g + 37 = 173.20 What is the cost of the game?
Answer:
$45.40
Step-by-step explanation:
3g + 37 = 173.20
3g + 37 -37 = 173.20 - 37
3g = 136.20
3g/3 = 136.30/3
g = 45.40

y-intercept of the line with slope of 2 and
through the point ( 14,3)
Answer: -25
Step-by-step explanation:
I used point-slope form [y-3=2(x-14)] and the Y intercept is -25
y= -3x-2
6x+2y= -4
What is the solution to this problem?
1 Substitute y=-3x-2y=−3x−2 into 6x+2y=-46x+2y=−4.
-4=-4−4=−4
2 Since -4=-4−4=−4 is redundant information, this is a dependent system.

Step-by-step explanation:
Substitute
1) 5(25)-100
125-100=25
2) 4*4*4=64
3)2(5)-20
=10-20
-10

6) 4(20-5)
4(15)
60
7)6(4)+(3*3)
24+9
33
Step-by-step explanation:
For all of these problems, we are given the values of the variable x.
Now, we just need to input them into the equations.
1) 5x-100 x=25
5(25)-100
125-100= 25
2) x^3 x=4
4^3= 4×4×4= 64
3) 2x-20 x=5
2(5)-20
10-20= -10
4) 7x+25 x=4
7(4)+25
28+25= 53
5) x^3+9 x=3
3^3+9= (3×3×3)+9
27+9= 36
6) 4(x-5) x=20
4(20-5)
20(4)-5(4)
80-20= 60
7) 6x+y^2 x=4 and y=3
6(4)+3^2
24+(3×3)
24+9= 33
Hope this helps! :)
