33. Jessica locates her garden using a coordinate grid with yards as the units. The two points
(-5, -2) and (-8, -3) represents the two corners of the garden. Approximately how far
apart are the two corners?
O
A 2 yards
B. 3.2 yards
C. 4 yards
D. 10 yards
They are approximately 4 yards. Look at a coordinate grid and locate where (-5, -2) and (-8, -3) are and you will see they are 4 yards apart. The answer would be C.
Is (x-3) a factor of (x3 - 3x2 + 2x + 2)?
SHOW FULL WORK
Answer:
No
Step-by-step explanation:
If (x - 3) is a factor then x = 3 is a root and the polynomial will equal zero for x = 3 , that is
3³ - 3(3)² + 2(3) + 2
= 27 - 3(9) + 6 + 2
= 27 - 27 + 8
= 8
since the polynomial ≠ 0 for x = 3 then (x - 3) is not a factor

Jake has 3 more than twice the number of marbles that Kylie has. Let m represent the number of marbles Kylie has.
The expression ____represents the number of marbles Jake has.
Answer:
2m + 3
Step-by-step explanation:
Jake has 3 more than twice the number of marbles that Kylie has. Let m represent the number of marbles Kylie has.
3 + twice of Kylie's marbles = twice of Kylie's marbles + 3
The amount of marbles kylie has is represented with m, making it (2 x m) + 3 = 2m + 3.

5. Usain Bolt holds the record for the fastest time in
the 100 meter dash. He first broke the record in
2008 when ran the 100 meter dash in 9.683 seconds.
In 2009, he ran the 100 meters in 9.572 seconds.
Tell whether each sentence is True of False.
5a. Rounded to the nearest tenth, O True False
both times are the same.
5b. Rounded to the nearest whole O True False

5c. Usain's time in 2009 was O True False
faster than his time in 2008.
Step-by-step explanation:
5a- rounding to nearest 10th 9.683 = 9.7
rounding to nearest 10th 9.572 = 9.6 both times are not same so false
5b rounding to near est whole no

help me with angle sum theorem please what is y
Answer:
y = 140
Step-by-step explanation:
All angles inside the triangle will equal 180
Set your formula up as
180 = x + 120 + 20
180 - 120 - 20 = x
40 = x
y+x will also equal 180, therefore
180 = y + x
180 = y + 40
180 - 40 = y
140 = y

How do I solve this using Substitution??
Answer:
-1
Step-by-step explanation:
so -x-6 and x-4 are both = to y so that means they are both = to each
other so -x-6=x-4 add x to both sides -6=2x-4 add 4 to both sides 2x = -2 simplify by divide by 2 so x=-1
Answer:
Take the second equation and add 4 to both sides, this gives you x=y+4. The plug in y+4 on the first equation, so y=-(y+4)-6, distribute the negative to everything inside the parentheses, and you get y=-y-4-6. Combine like terms and you get y=-y-10, then add y to both sides, you get 2y=-10, divide both sides by 2 and you get y=-5.
Then plug -5 into the second equation and you get -5=x-4, add 4 to both sides and you get -1=x.
If you want to check your answer, just plug in x and y to either of the equations and see if it makes a true statement.

Help me solve this problem
Answer:
The length of the missing leg is six
Step-by-step explanation:
Assuming that this is a right triangle, you can use the Pythagoras theorem
12^2+x^2=sqrt180^2
144+x^2=180
x^2=36
x=6
Therefore, the length of the missing leg is six.
Answer:
Taking the above as a right angled triangle...
Pythagoras' rule can be applied to get the Missing side.
It goes...
Hyp² = Opp² + Adj²
Which translates to Hypotenuse, Opposite and Adjacent respectively.
Hyp = √180
Opp= 12
So we're missing Adj
Making adj the subject.
Adj = √ Hyp² – Opp²
= √[(√180)² – (12)²
= √ [ 180 – 144]
= √36
Adj = 6ft.
please help me find the total surface area
Answer:
Area of the figure = 64 cm²
Step-by-step explanation:
To find the total surface area (TSA) of the figure, we must add the areas of the 4 triangles along with the area of the square.
Given,
Altitude of triangle (h) = 6 cmBase of triangle (b) = 4 cmSide of the square (h) = 4 cmBy using these values,
Area of the triangle = ½ bhArea of the triangle = ½ × 6 × 4Area of the triangle = ½ × 24Area of the triangle = 12 cm²Now,
Area of the square = s²Area of the square = 4²Area of the square = 16 cm²So, from this,
Area of the figure = (4 × Area of the triangle) + Area of the square Area of the figure = (4 × 12) + 16Area of the figure = (48) + 16Area of the figure = 64 cm²•°• The TSA of the figure is 64 cm².

Which is the equation of a hyperbola with directrices at x = ±3 and foci at (4, 0) and (−4, 0)?
Answer:
[tex]\frac{x^2}{12}-\frac{y^2}{4}=1[/tex]
Step-by-step explanation:
Since our foci are located on the x-axis, then our major axis is going to be the horizontal transverse axis of the hyperbola:
Formula for hyperbola with horizontal transverse axis centered at origin
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]Directrices -> [tex]x=\pm\frac{a^2}{c}[/tex]Foci -> [tex](\pm c,0)[/tex] where [tex]a^2+b^2=c^2[/tex][tex]a>b[/tex]Since we are given our directrices of [tex]x=\pm3[/tex] and foci of [tex](\pm4,0)[/tex], then we can set up the directrices equation to solve for [tex]a^2[/tex]:
[tex]x=\pm\frac{a^2}{c}\\ \\\pm3=\pm\frac{a^2}{4}\\ \\12=a^2[/tex]
Now we can determine [tex]b^2[/tex] to complete our equation for the hyperbola:
[tex]a^2+b^2=c^2\\\\12+b^2=4^2\\\\12+b^2=16\\\\b^2=4[/tex]
Therefore, our equation for our hyperbola is [tex]\frac{x^2}{12}-\frac{y^2}{4}=1[/tex]

Use the function: g(x) = (x + 2)(x - 1)(x - 2) a) Find the zeros of the function. b) Find the y-intercept of the function.
Answer:
The zeros are -2, 1, and 2
Step-by-step explanation:
You have to set each individual equation equal to zero.
ex: (x+2) x+2=0 move the number to the right hand side to get x alone x=-2
as for the y intercept I don't know
Answer:
see explanation
Step-by-step explanation:
g(x) = (x + 2)(x - 1)(x - 2)
To find the zeros let g(x) = 0 , then
(x + 2)(x - 1)(x - 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
x - 2 = 0 ⇒ x = 2
The zeros are x = - 2, x = 1, x = 2
To find the y- intercept substitute x = 0 into g(x)
g(0) = (0 + 2)(0 - 1)(0 - 2) = 2(- 1)(- 2) = 2 × 2 = 4
The y- intercept is 4 or (0, 4 )

A cell phone company conducted a survey to determine if customers were satisfied with their cell phone service. The survey sample consisted of all customers who had contacted the company within the past year and who agreed to participate. Of the 420 customers surveyed, 65% reported that they were not satisfied with their service.
Which statement about this sample is true?
A Exactly 65% of all customers are not satisfied with the cell phone service.
B The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,
C The sample might not be representative of the population because, in general, satisfied customers have no reason to contact the company.
D No generalizations can be made from this sample because the sample size is too small.
The statement that is true about the given sample is that;
B. The sample includes all customers who made complaints to the company within the last year, and therefore is representative of the population. ,
Sample Statistics Interpretation
We are given;
Sample size; n = 420
Sample proportion; p^ = 65%
Now, from the sample size and proportion, we can say that;
Exactly 65% of the surveyed customers were not satisfied with the cell phone service. Now, this only represents those surveyed and not the entire population. Thus it is not exactly 65% of all customers that are not satisfied with the cell phone service.
Option B is correct because the 420 customers surveyed is a sample from the population of all their customers within the last year.
