Answer: No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
y=3x²+3x+1,find the value of the discrimination
Answer:
Step-by-step explanation:
a = 3
b = 3
c = 1
Discriminate = sqrt(b^2 - 4ac)
Discriminate = sqrt(9 - 4*3*1)
Discriminate = sqrt(9 - 12)
Discriminate = sqrt(-3)
What negative value means that there are no real roots and the y intercept = 1. You should always graph this kind of question, which I am doing for you. I use Desmos which is a very handy program.
You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.

This is a familiar conversion problem:
[tex]3.3 \times {10}^{2} lightyears \times \frac{5.9 \times {10}^{12} miles}{1 \: lightyear} [/tex]
[tex] = 1.95 \times {10}^{15} \: miles[/tex]
Answer:
see below
Step-by-step explanation:
3.3 × 10^2 light years
one light year is 5.9 × 10^12 miles
you need to multiple these two values
3.3 × 10^2 light years × 5.9 × 10^12 miles/light year =
= (3.3 × 5.9) × 10^2 × 10^12
= 19.47 × 10^(2 + 12)
= 1.947 × 10^1 × 10^14
= 1.947 × 10^15 miles

Use the box plot to explain what you know about the spread of this data set.
Answer:
Step-by-step explanation:I found the answer only/3fcEdSx this web[tex]^{}[/tex]site. It seems correct! Link Below!
bit.[tex]^{}[/tex]
Answer:
The range of the data is 75 - 21 = 54 (the difference between the two "whiskers"
The median of the data is 50 (middle line inside the box)
The first quartile "Q1" is 34 (left edge of the box). This means that 25% of the values are < 34.
The third quartile "Q3" is 69 (right edge of the box). This means that 25% of the values are > 69.
The interquartile range is 69-34 = 35. (subtracting Q3 - Q1) 50% of the data falls in this range, from 34 -69. 50% of the data falls in the box.

The surface area is what?? These are the numbers 14 cm, 14cm, and 10cm
Pls answer fast
Since the shape is a square pyramid, the base would be 14 by 14. The area of one triangle would be 10 times 14 times 1/2 = 70. 70 times 4 = 280. 14 times 14 = 196
196 + 280 = 476
Final answer = 476

Find the value of x in each figure. Show work
Answer:
1. x=28 degrees 2. x=70 degrees
Step-by-step explanation:
QUESTION ONE:
I know that 3x=84, so all I need to do is divide both by 3. I get x=28.
QUESTION TWO:
I can use vertical and complementary angles for this problem. I know that the smaller complementary angle is equal to 160-180, that's 20. Therefore, I get 90=20+x. If I simplify I get 70=x, because 70+20=90.

In the diagram below, a right circular cone with a radius of 3 inches has a slant height of 5 inches, and a right cylinder with a radius of 4 inches has a height of 6 inches. Determine and state the number of full cones of water needed to completely fill the cylinder with water.
this is the correct answer
The number of full cones of water needed to completely fill the cylinder with water is 8 cones.
What is Volume of cylinder?The Volume of Cylinder is, V= πr²h
where r is the radius, h is the Height of cylinder.
Given:
Cylinder:
Height= 6
Radius = 4
Volume of cylinder = πr²h
= πx 4 x 4 x 6
= 96π in³
and, Cone:
Radius = 3
l = 5
h= √5²-3²
h = √25-9
h= √16
h= 4 inch
So, Volume of Cone = 1/3 πr²h
= 1/3 x π x 3 x 3 x 4
= 12π in³
Thus, number of full cones of water needed to completely fill the cylinder with water
= 96π in³/ 12 π in³
= 8 cones

find the slope between the pair of points.
through: (1,-3) and (2,3)
Answer:
6
Step-by-step explanation:
Slope = delta y/delta x
[tex]slope = \frac{y_1-y_2}{x_1-x_2}[/tex]
Slope = (-3-3)/(1-2)
Slope = -6/-1
Slope = 6
Answer:
6
Step-by-step explanation:
Given :-
Two points (1,-3) and (2,3)And we need to find the slope of the line passing through the two points . The slope of the line passing through two points is the difference of y coordinates divided by difference of x coordinates.
Substituting the respective values :-
[tex]:\implies[/tex] m = y₁ - y₂/ x₁ - x ₂
[tex]:\implies[/tex] m = -3 -3 / 1 - 2
[tex]:\implies[/tex] m = -6/-1
[tex]:\implies[/tex] m = 6
Hence the slope of the line is 6.

Step-by-step explanation:
Given
The attached table
[tex](a)\ f^{-1}(-15)[/tex]
This represents an inverse function.
So, we look into x row for its value.

Cameron's father wouldn't allow her to play with her friends until her room was spotless. Cameron hated cleaning; it was boring. She sat on her bed, taking in the chaos that surrounded her. There were piles of books on her desk, her bed was unmade, and her clean laundry sat in a basket by the door. It would take forever to tidy this room! Suddenly, Cameron had a brilliant idea. She rummaged through her sports bag and found a stopwatch. She would turn the chore into a game by timing herself. Cameron started the timer and buzzed frantically about the room, putting clothes and books away before making the bed. About fifteen minutes later, her room was completely organized. Satisfied with her time, she now needed her father's approval. Upon inspection, Cameron's father seemed happy with the results. With her chores complete, Cameron raced outside to meet her friends.
One conflict in the story is that
(Links to an external site.)
A) Cameron does not think her room is messy.
B) Cameron does not want to clean her room.
C) Cameron's friends are waiting for her.
D) Cameron's father is upset with her.
Answer:
B
Step-by-step explanation:
how is that mathematics ?
this is psychology or something related.
A is clearly wrong. she knows it is messy.
C is not a conflict. this is the precondition for the conflict.
D no, that is nowhere stated. wrong.
that leaves B if it was not clear from the beginning.

A jeweler was interested in the relationship between the weight of a diamond, in carats, and the market price of the diamond, in dollars. The jeweler selected a random sample of diamonds with the same cut and quality and recorded the weight and market price of each diamond.
Required:
Draw the residual plots that provides evidence that the condition that there is a linear relationship between weight and market price has not been met.
Answer:
The answer is "ski slope from left to right".
Step-by-step explanation:
It has been shown by the jeweler's value in the standardized residuals, it is clear that a linear relation is not fulfilled between mass and market price.
And you know that a normality test would be violated if a curve exists upon on remainder of a story. Because the constant variance will not be received. That violated the static hypothesis.
There B, C, D, E does have the consistent variance as seen in the figure following the linear hypothesis of equal variances however the curvature is shown by a residual plot that has not fulfilled requirements, but the direct correlation between mass and current value is not fulfilled.
A circle is centered about the point (2, 0). The point (0, 1) is on the circle. Which statement proves that the point (4, 1) is also on the circle?
Answer:
Step-by-step explanation:
the circle is at the origin and (0,4) is a point on the circle then the radius of the circle is:
r^2=0^2+4^2
r^2=16
r=4
so we can check that the other point is four units from the origin and thus also on the circle...
d^2=2^2+6^2
d^2=4+36
d^2=40
since d^2>r^2, (2,6) is outside the circle
