write the equation for the line that has a slope of -4 and passes through the point (-2, 2)
Answer:
y = -4x - 6
Step-by-step explanation:
y = -4x + b
2 = -4(-2) + b
2 = 8 + b
-6 = b

Help pleasee geometry is hard
Answer:
Step-by-step explanation:
The formula for arc length is
[tex]AL=\frac{\theta}{360}*\pi d[/tex] where theta is the central angle. We are given the central angle when we are told that the measure of arc EFG is 240 degrees. The diameter is given as 36, so filling in:
[tex]AL=\frac{240}{360}*\pi (36)[/tex] which can be simplified down a bit to
[tex]AL=\frac{2}{3}*\pi (36)[/tex] and a bit more to
[tex]AL=2\pi(12)[/tex] which gives us, finally,
[tex]AL=24\pi[/tex]
I can't tell which of your answers matches this one because they're much too small to read.

Find the volume of this cone.
Use 3 for T.
V = Tip?h
[?]cm3
19 cm
V ~
6cm
Answer:
81 cm ^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height
We are given the diameter of 6 so the radius is 1/2 the diameter
r = 1/2 (6) = 3
V = 1/3 pi r^2 h
= 1/3 ( 3) * (3) ^2 * 9
= 81 cm ^3

determine the zeros of the function f(x)=3x^2-7x+1.
Answer:
The zeros of the function will be when f(x) = 0. As 0 = 3x^2 - 7x + 1, you can use the quadratic formula to solve, finding that x = (7 + sqrt(37))/2 or (7 - sqrt(37))/2.
Determine the slope of the line
Answer:
Option B, -3/2
Step-by-step explanation:
The line passes through (4,0) and (0,6)
so, the slope will be
(6-0)/(0-4)

Find the factorization of the polynomal below 64x^2 + 48x + 9
Answer:
(8x + 3)²
Step-by-step explanation:
Since our polynomial is 64x² + 48x + 9, we multiply 64x² by 9 to get 64x² × 9 = 576x² since we cannot simplify the expression any further.
Next, we need to find the factors of 576x² that add up to give 48x, these are 24x and 24x.
So the expression is re-written as
64x² + 48x + 9 = 64x² + 24x + 24x + 9
Writing out all the common factors, we have,
64x² + 48x + 9 = 8x × 8x + 3 × 8x + 3 × 8x + 3 × 3
Factorizing we have
64x² + 48x + 9 = 8x(8x + 3) + 3(8x + 3)
64x² + 48x + 9 = (8x + 3)(8x + 3)
64x² + 48x + 9 = (8x + 3)²

Question 1
Answer:
DC = 2
Step-by-step explanation:
From the diagram, AD (i.e the angle bisector) bisects the angle into 2 equal parts. Thus, BD and DC are equal.
BD = 2
DC = BD = 2
DC = 2
This can further be explained as illustrated below:
We'll begin by calculating AD. This can be obtained as follow:
Angle A = 30°
Opposite = BD = 2
Hypothenus = AD =?
Sine A = Opposite (BD) /Hypothenus (AD)
Sine 30 = 2 / AD
0.5 = 2 / AD
Cross multiply
0.5 × AD = 2
Divide both side by 0.5
AD = 2 / 0.5
AD = 4
Finally, we shall determine DC. This can be obtained as follow:
Angle A = 30°
Hypothenus = AD = 4
Opposite = DC =?
Sine A = Opposite (DC) /Hypothenus (AD)
Sine 30 = DC / 4
Cross multiply
DC = 4 × Sine 30
DC = 4 × 0.5
DC = 2

d= 0m
In case of Ryan:
slope =speed = 47.5-35=6-4 = 12.5/2 =6.25
y-35=6.25(x-4)
y-35=6.25x-25

What is the explicit formula for this sequence?
-8,-3, 2, 7, ...
O A. an = 12 + (n - 1)5
O B. an = 5+(n-1)(-8)
O C. an=-8+ (n - 115
O D. an= -8+ (n - 1)(-5)
Answer:
[tex]\text{C. }a_n=-8+(n-1)5[/tex]
Step-by-step explanation:
The explicit formula for an arithmetic sequence is given by [tex]a_n=a_1+(n-1)d[/tex], where [tex]a_n[/tex] is the [tex]n[/tex]th, [tex]a_1[/tex] is the first them of the sequence, and [tex]d[/tex] is the common difference.
In the given sequence -8, -3, 2, 7, we can see that we're adding 5 to each term. Therefore, the common different is positive five (+5). We can also identify the first term is -8. Therefore, we have:
[tex]a_1=-8[/tex] [tex]d=5[/tex]Thus, the explicit formula for this sequence is:
[tex]\boxed{a_n=-8+(n-1)5}[/tex]

Mr. Fischer, a bilingual teacher, teaches a mathematics class composed of native English speakers and English language learners (ELLs). He has introduced a new topic with new vocabulary words in which he presented the vocabulary words with several examples. Which of the following strategies should Mr. Fischer use next to check each student's understanding of the vocabulary words?a. having students look up the definition online to see if it matches what Mr. Fischer told themb. having students copy down the definition for each word that Mr. Fischer wrote on the board in Englishc. placing students in groups so each student can explain the vocabulary terms to their peers in Englishd. having students write a definition for each term in their own words in their native language
Answer:
D. having students write a definition for each term in their own words in their native language
Step-by-step explanation:
In Mr Fischer's mathematics class, we are presented with two categories of learners. Those that are native speakers of English and those who are learners of English.
Both categories of students would show their understanding best in this lesson if they were to write in their own native language.
The native english-speakers would have no issues writing in English, but those who are English learners would have problems communicating their understanding of the lesson in English. So it is best they give their definitions in their native language.
