Answer:
V = 2261.9
Step-by-step explanation:
The formula to find the volume of a cylinder is:
V = pi • r² • h
Answer:
If you learned that you express pi is π: 720π [tex]cm^3[/tex]
If it says pi is 3.14: 2260.8 [tex]cm^3[/tex]
Step-by-step explanation:
oki, so the rule to find the area of a circle is r x r x π
which will be 36π in this situation!
So we multiply the area of the circle by the height next, and get 720π
if we have to say pi is 3.14, the answer should be 2260.8

Solve for q. Write your answer as “q=___”
Answer:
7q-46= 3q +6
7q-3q = 6+ 46
4q= 52
4q/4= 52/4
q= 13
Answer:
Hello! q = 22
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees so...
22 × 7 = 154 154 - 46 = 108
3 × 22 = 66 66 + 6 = 72
108 + 72 = 180 therefore q = 22 hope that helps!

Given that x(3x+1) - 2(3x-5) = 3x^2 + ax + 10 find the value of a
Answer:
a= -5
Step-by-step explanation:
Answer:
a = -5.
Step-by-step explanation:
x(3x+1) - 2(3x-5)
= 3x^2 + x - 6x + 10
= 3x^2 - 5x + 10
Comparing this term by term with
3x^2 + ax + 10 we see a = -5.

Noah is trying to draw a triangle with a angle and side lengths

.
He uses his ruler to draw a 4 cm line segment.
30°
• He uses his protractor to draw a angle on one end of the line
segment.
ANSWER BOTH QUESTIONS ILL GIVE BRANLIEST AND LOTS OF POINTS .
Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.
How to solveYes, there is a different triangle Noah could draw. Since Noah has only drawn one side and one angle, he can create two different triangles using the Angle-Side-Side (A S. S) ambiguity
To find the other possible triangle, we need to calculate the angle opposite the 6 cm side. In this case, the given angle is 30°. Using the sine rule, we can find the sine of the opposite angle (let's call it θ):
sin(θ) / 6 = sin(30°) / 4
sin(θ) = (6 * sin(30°)) / 4
sin(θ) ≈ 0.5
θ ≈ 30°
Since the sum of angles in a triangle is 180°, the other angle in the triangle is:
180° - 30° - 30° = 120°
Now, we can use the sine rule again to find the length of the side opposite this new angle:
x / sin(120°) = 6 / sin(30°)
x ≈ 6 * sin(120°) / sin(30°)
x ≈ 10.39 cm
Therefore, Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.

Answer:
55
Step-by-step explanation:
You're looking at a right triangle, with both legs being complementary forming 90
Since you know one measurement, 35, substract that from 90 and you get your missing angle.
90-35 = 55
Answer:
measure of the missing angle=55°
Step-by-step explanation:
Hi there!
We're given a right angle (as indicated by the red marking) being split into a 35° angle and another angle of unknown degree. Let's call the value of this angle x.
Because the given angle is 90° being split apart by the 35° angle and x, x+35° will equal to 90° (this is called parts whole postulate, where a whole (the 90° angle) is equal to the sum of its parts (the 35° angle and the x° angle))
so we can solve the equation as:
x+35°=90°
subtract 35 from both sides
x=55°
so the measure of the missing angle is 55°
Hope this helps! :)
finding the axis of symmetry of its graph y=3x^2-18x+1
Answer:
x=3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
y = 3x² - 18x + 1 ← is in standard form
with a = 3, b = - 18
x = - [tex]\frac{-18}{6}[/tex] = 3
Axis of symmetry is x = 3

Step-by-step explanation:
here are the coirdantes:

So if u try the first one
f(x)=x+3
3(1)=3

So it does not work
The second choice:
f(x)=-4x-3
3(-4)
-12-3=-15
It does not work
The third choice:
f(x)=1/4x+3
3(1/4)=3/4
3/4+3=3 3/4
The last one:
f(x)=4x+3
9(4)=36
36+3=39
As you can see the last one works

A carpenter has two pieces of wood. He wants to find the density of each piece.
The first piece came from a birch tree. The piece of birch wood measures 2 meters by 4 meters by 3 meters and weighs (mass) 16 kilograms.
The second piece came from a cypress tree. The piece of cypress wood measures 3 meters by 5 meters by 2 meters and weighs (mass) 15.3 kilograms.
Which piece of wood has a greater density?
Answer:
The wood from the birch tree has a greater density than the wood that came from the cypress tree.
Step-by-step explanation:
Density formula: mass/volume
2 times 4 times 3=24 meters for the volume
Birch tree: 16/24 is the density
3 times 5 times 2=30 meters for the volume
Cypress tree: 15.3/30 is the density
If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.
So birch tree: 0.6 repeating is the density
Cypress tree: 0.51 is the density
Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.
Hope I helped, have a nice day :)

The distance far up the side of the house will the ladder reach now will be 15.2 feet.
The distance far up the side of the house will the ladder reach now will be 15.2 feet.
A 40 foot ladder is set against the side of a house so that it reaches up 24 feet.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Let the distance between the base of house and ladder foot is x feet.
By using Pythagoras theorem;
40² = 24² + x²
⇒ 1600 - 576 = x²
⇒ x² = 1024
⇒ x = 32 feet
If Lily grabs the ladder at its base and pulls it 4 feet farther from the house.
Then, the distance between the base of house and ladder foot = x + 5
Height of house is h feet
40² = h² + (x + 5)²
⇒ 1600 = h² + (32 + 5)²
⇒ 1600 = h² + 1369
⇒ h² = 1600 - 1369
⇒ h² = 231
⇒ h = √231
⇒ h = 15.19 feet
Therefore, the distance far up the side of the house will the ladder reach now will be 15.2 feet.

What is the equation of the line that passes through the points
(6,8) and (-10, – 7)?
Answer:
y=15/16x+19/8
Step-by-step explanation:
Hi there!
We are given the points (6,8) and (-10, -7) and we need to find the equation of the line
There are 3 ways to write the equation of the line, but the most common format is slope-intercept form, or y=mx+b form, where m is the slope and b is the y intercept
First, we need to find the slope
The formula for the slope calculated from two points is (y2-y1)/(x2-x1), where (x1, y1) and (x2,y2) are points
Our (x1,y1), and (x2,y2) are (6,8) and (-10, -7)
we can label their values to avoid confusion:
x1=6
y1=8
x2=-10
y2=-7
substitute into the formula
m=(-7-8)/(-10-6)
m=15/16
so the slope is 15/16
here's our equation so far:
y=15/16x+b
we need to solve for b
Because the line will pass through (6,8) and (-10,-7), we can substitute either one of them into the equation to solve for b
Let's take (6,8) as an example
Substitute x as 6 and y as 8
8=15/16(6)+b
Multiply
8=45/8+b
subtract
19/8=b
therefore, the equation of the line is:
y=15/16x+19/8

O B. (7) > g(10)
OC. F(5) < g(3)
O D.g(8) = f(5)
Answer:
[tex](c)\ f(5) < g(3)[/tex]

Given
[tex]f(n) = 2(n-1) -1[/tex]
[tex]g(n) = 3n + 6[/tex]
Required
Which is correct
[tex](a)\ g(6) < f(6)[/tex]
Calculate g(6) and f(6)
[tex]f(n) = 2(n-1) -1[/tex]
[tex]f(6) = 2(6 - 1) -1 = 2*5-1=9[/tex]
[tex]g(n) = 3n + 6[/tex]
[tex]g(6) =3*6 +6 =24[/tex]
(a) is false, because g(6) > f(6) i.e. 24 > 9
[tex](b)\ f(7) > g(10)[/tex]
Calculate f(7) and g(10)
[tex]f(n) = 2(n-1) -1[/tex]
[tex]f(7) = 2*(7-1)-1=2*6-1=11[/tex]
[tex]g(n) = 3n + 6[/tex]
[tex]g(10) =3*10+6=36[/tex]
(b) is false, because f(7) < g(10) i.e. 11 <36
[tex](c)\ f(5) < g(3)[/tex]
Calculate f(5) and g(3)
[tex]f(n) = 2(n-1) -1[/tex]
[tex]f(5) =2 *(5-1)-1 = 2*4-1=7[/tex]
[tex]g(n) = 3n + 6[/tex]
[tex]g(3) = 3*3+6=9+6=15[/tex]
(c) is true, because f(5) < g(3) i.e. 7 <15
Answer:
the answer is f(7) > g(10) because 63 > 36.
