5. Find the volume of the cylinder. Leave your
answer in terms of t.
8 cm.radius
8 cm.height
Answer:
[tex]512\pi[/tex]
use the formula
length=2
width=2
height=3
Answer:
12
Step-by-step explanation:
The computation of the volume of the rectangular prism is shown below:
As we know that
The volume of the rectangular prism is
= length × width × height
where
Length is 2
width be 2
And, the height be 3
So, the volume of the rectangular prism is
= 2 × 2 × 3
= 12

What is the measure of angle 4?
angles 1,3,5,6,7, and 8 are 73 degrees. angles 2 is 107 degrees
Answer:
34 Deg
Step-by-step explanation:
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34
What is the value of this expression when c=-4 and d = 10?
1/4(c3+d2)
What is the value of this expression when c = -4 and d = 10 ? [tex] \frac{1}{4} [/tex] (c³ + d²)
Answer:-Given:-[tex] \frac{1}{4} [/tex] (c³ + d²) where c = -4 and d = 10
To Find:-The value of the expression [tex] \frac{1}{4} [/tex] (c³ + d²)
Solution:-[tex] \frac{1}{4} [/tex] (c³ + d²) [Given expression]
Now, putting the value of c = -4 and d = 10 , we get,
[tex] \frac{1}{4} [/tex] { (-4)³ + (10)² }
[tex] \frac{1}{4} [/tex] ( -64 + 100 )
[tex] \frac{1}{4} [/tex] ( 36 )

I'm stuck on two polynomial questions and any help would be greatly appreciated!
1. (4x-3y) is a factor of [tex]a^{2}x^{2} -b^{2}y^{2}[/tex] what is the value of [tex]a^{2} + b^{2}[/tex]?
2. [tex]x^{2} +19x+c[/tex] has a factor of (x+7) what is the value of c?
Answer:
1) 252) 84Step-by-step explanation:
#1
a²x² - b²y² = (ax + by)(ax - by)
Since (4x - 3y) is one of the factors, we have:
a = 4, b = ± 3The value of a² + b² is:
4² + (±3)² = 16 + 9 = 25#2
x² + 19x + c, has a factor of (x + 7).
It means the equation:
x² + 19x + c = 0 has one root of x₁ = -7.Sum of the roots:
x₂ + (- 7) = -19/1 x₂ = -19 + 7x₂ = -12Product of the roots:
x₂*(-7) = c-12*(-7) = cc = 84I need help guys, please!.

What value of y makes the equation 4x – 3y = 17 true, when x = 2?
Answer:
y = -3
Step-by-step explanation:
4x – 3y = 17
x = 2
4(2) - 3y = 17
8 - 3y = 17
-3y = 9
y = -3
Answer:
y= -3
Step-by-step explanation:
if x =2, substitute
4(2) - 3y = 17
8-3y = 17
(add 3y to both sides)
8= 17 + 3y
(subtract 17 from both sides)
8-17=3y
-9= 3y
(divide both sides by 3)
-9/3=y
y= -3

Answer:
[tex] - 12288 \div {2}^{11} = - 6 \\ forth \: answer \: is \: correct[/tex]
Answer:
4th option
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
To find a₁ use a₁₂ = - 12288 , then
a₁ [tex](2)^{11}[/tex] = - 12288 , that is
a₁ × 2048 = - 12288 ( divide both sides by 2048 )
a₁ = - 6
Then the explicit formula is
[tex]a_{n}[/tex] = - 6 . [tex]2^{n-1}[/tex]

if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
Answer:
m = rise/run = 270/20.5 = 13.17
Step-by-step explanation:
Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is
m = rise/run = 270/20.5 = 13.17
