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
Select the expression that shows the distributive property applied to
13(2+9).

Joan spilled 750ml of fruit punch while pouring into cups from a bucket which held 3.75 litres of punch. Calculate what % of punch was spilled
Answer:
Percentage of punch spilled = 20%
Step-by-step explanation:
1 liter = 1000 ml
750 ml = 750/1000
= 0.75 liter
Quantity of fruit punch spilled = 0.75 liter
Total volume of fruit punch in the bucket = 3.75 liters
Calculate what % of punch was spilled
Percentage of punch spilled = quantity of punch spilled / Total quantity of punch × 100
= 0.75 liter / 3.75 liters × 100
= 0.2 × 100
= 20%
Percentage of punch spilled = 20%
Multiply the binomials:
(a-2) • (a-8)
Answer:
a^2 -10a +16
Step-by-step explanation:
(a-2) • (a-8)
FOIL
first a*a = a^2
outer: a * -8 = -8a
inner: -2 *a = -2a
last: -2 *-8 = 16
Add them together
a^2 -8a -2a+16
Combine like terms
a^2 -10a +16
Answer:
Step-by-step explanation:
(a-2) (a-8) , distribute a over (a-8) then -2 over (a-8)
a²-8a-2a+16, combine like terms
a² -10a +16

How to change the decimal 4.5 into a fraction
4.5
= 4.5/1
= 4.5/1.0
= 45/10 [Shifting the decimal to right]
= 9/2 [Reducing to the simplest form]
So, the answer is 9/2.
Imagine that you are given two linear equations in slope-intercept form. You
notice that the slopes are different, but the yintercepts are the same. How
many solutions would you expect for this system of equations?
O A. 1
O B. cannot be determined
O C. O
D. infinitely many
Answer:
Option A
Step-by-step explanation:
If the system of equations are,
y = m₁x + b
y = m₂x + b
Since, m₁ ≠ m₂ both the lines will be different (not parallel)
Therefore, the will be at least one solution of the given system of equations.
Option A will be the answer.
Eric and Shiloh each have a savings account. The ratio of Eric’s account balance to Shiloh’s account balance is 4:3. Together they have a total of $140 in their accounts. Use the tape diagram below to help you determine the balance of Eric’s account. [Type your answer as a number.]
Answer:
Eric 80
Step-by-step explanation:
Take 4+3 = 7
140 /7 = 20
There is 20 in each block
Eric gets 4 of the blocks so 4*20 = 80
Shiloh gets 3 of the blocks 3*20 = 60
Answer:
80
Step-by-step explanation:
4 : 3
4x + 3x = 140
7x = 140
x =20
4*20 = eric's amount
= 80

What is the slope of this?
Answer:
-3/2
Step-by-step explanation:
the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.
so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.
so, the slope is
-6/4 = -3/2

Answer: Sam did not get the question correct.
I believe he squared it wrong.
Step-by-step explanation:
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.
Can someone help me with this math homework please!
In case of Nina:
slope of graph = speed = 48-32/6-4 = 16/2 =8
y-32 =8(x-4)
y-32=8x-32
y=8x
d=8t
at x= 0 i.e at t= 0
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
y=6.25x+10
d=6.25t+10
at t = 0, d= 10m
RYAN had a head start of 10 m

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]
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

C. 16x^2 - 22xy + 49y^2
D. 16X^2 - 56xy + 49y^2
Answer:
D. [tex]16x^2}-56xy+49y^2[/tex]
Step-by-step explanation:
A and B aren't correct because the last term is negative.
The factored form of D is [tex](4x-7y)^2[/tex]

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]
