Write the correct association below each scatter plot.
POSITIVE LINEAR, negative linear, nonlinear ,none.
Answer:
From left to right:
Negative, positive, none, nonlinear
1 is negative bc it has a negative slope
2 is positive because it has a positive slope
3 has no correlation because there is no pattern
4 is no linear because it’s not in a line, essentially. (This would be a parabola)
Find the roots/zeroes of the following polynomial
x^2−19=6
Answer:
x=5 and x=-5
Step-by-step explanation:
1. first you would subtract 6 from both sides to set the equation = to zero.
2. The equation would then be x^2-25=0.
3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0
4. by the zero product property, the roots are 5 and -5.
How many times do you multiply 5 by itself if the exponent is 56?
Answer:
56 times
Step-by-step explanation:
An exponent are a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).

Domain or range function or not And explain
In a lottery game, a machine has 48 balls marked with numbers from 1-48 and six of them are taken out at random. A player picks six of these numbers, trying to match the six balls that come out of the machine in any order. If exactly 4 of those 6 numbers match those drawn, the player wins third prize. What is the probability of winning this prize? Give answer as a fraction or decimal rounded to 4 significant digits in either standard or scientific notation. Hint: there is more than one way to win, take into consideration all the ways to pick the 4 winning numbers and the 2 losing numbers.

m5=75 degrees
m11=75 degrees
m16=65 degrees
To find 5, realize angles 5 and 8 equal 180, because they make up a straight line, line d.
180-105=75
To find 11, it is the same as finding 7. Just look at the similar sizes. Angle 7 is the same at angle 5, just turned around. There’s a term for this pair angles that I don’t remember now but it exists. Now, lines a and b are parallel, so their angles between lines that intersect both are the same too. This means, as angle 5 equals angle 7, angle 7 equals angle 11.
To find 16, we use a combination of the methods used in finding the previous angles.
180-115=65 degrees is angle 4
Angle 4=Angle 16
Knowing the two angles given and that lines a and b are parallel, you could find the measurements of every angle in each intersection if you wanted to.
Answer:
m5=75 degrees
m11=75 degrees
m16=65 degrees

Chidi measured the angle of elevation
of a tree and found it was 38°. He then
valked 25 m towards the tree and
measured the angle of elevation again
bo be 50°.
Find the actual height of the tree
d Find the total distance to the bot-
tom of tree from Chidi's initial
position
Answer: 56.72 m, 72.6 m
Step-by-step explanation:
Given
The initial angle of elevation is [tex]38^{\circ}[/tex]
after walking 25 m, the angle of elevation is [tex]50^{\circ}[/tex]
In [tex]\triangle ABD[/tex]
[tex]\Rightarrow \tan 38^{\circ}=\frac{h}{x+25}[/tex]
[tex]\Rightarrow h=\tan 38^{\circ}(x+25)\quad \ldots(i)[/tex]
In [tex]\triangle ABC[/tex]
[tex]\Rightarrow \tan 50^{\circ}=\frac{h}{x}\\\\\Rightarrow h=x\tan 50^{\circ}\quad \ldots(ii)[/tex]
From (i) and (ii)
[tex]\Rightarrow x\tan 50^{\circ}=(x+25)\tan 38^{\circ}\\\Rightarrow 1.191x-0.781x=25\times 0.781\\\Rightarrow 0.4104x=19.532\\\Rightarrow x=47.59\approx 47.6\ m[/tex]
[tex]\Rightarrow h=47.6\times \tan 50^{\circ}=56.72\ m[/tex]
The distance of tree bottom and Chidi's is
[tex]\Rightarrow x+25=47.+25=72.6\ m[/tex]
What is the value of y in the figure below?
(7y + 27)
(15x - 5)
125°
Answer:
Simplifying
(7y + 27) + (15x + -5) = 125
Reorder the terms:
(27 + 7y) + (15x + -5) = 125
Remove parenthesis around (27 + 7y)
27 + 7y + (15x + -5) = 125
Reorder the terms:
27 + 7y + (-5 + 15x) = 125
Remove parenthesis around (-5 + 15x)
27 + 7y + -5 + 15x = 125
Reorder the terms:
27 + -5 + 15x + 7y = 125
Combine like terms: 27 + -5 = 22
22 + 15x + 7y = 125
Solving
22 + 15x + 7y = 125
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-22' to each side of the equation.
22 + 15x + -22 + 7y = 125 + -22
Reorder the terms:
22 + -22 + 15x + 7y = 125 + -22
Combine like terms: 22 + -22 = 0
0 + 15x + 7y = 125 + -22
15x + 7y = 125 + -22
Combine like terms: 125 + -22 = 103
15x + 7y = 103
Add '-7y' to each side of the equation.
15x + 7y + -7y = 103 + -7y
Combine like terms: 7y + -7y = 0
15x + 0 = 103 + -7y
15x = 103 + -7y
Divide each side by '15'.
x = 6.866666667 + -0.4666666667y
Simplifying
x = 6.866666667 + -0.4666666667y

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R
Step-by-step explanation:
So there ya go
D=R
and now bout the range ya gotta find the vertex, which is:
[tex] x = \frac{ - b}{2a} \: \: y = \frac{Δ}{4a} [/tex]
now pay attention
X=2/–2=–1
y=–(–1)²–2(–1)+3=4
Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]
Well, finally your answer is D

Answer:
58.5
Step-by-step explanation:
9 + 33 + 16.5 = 58.5
3x + y = 4
8x + 2y = 10
Answer:
I take it that we solve for x and y, so we have
3x + y = 4, so we have y = 4 - 3x
and plug that in to
8x + 2y = 10
8x - 6x + 8 = 10
so
2x = 2
x = 1
y = 4 - 3
y = 1
