What is the volume of the plastic rocket???
Answer:
A) 151 in³ or 151 cubic inches
Step-by-step explanation:
Volume of rocket = Volume of Cylinder + Volume of Cone
Step 1
Find the volume of the cylinder
Volume of a cylinder = πr²h
r = Diameter/2
= 5/2 = 2.5 inches
h = 6 inches
Hence,
π × 2.5² × 6
= 117.81 cubic inches
Step 2
Find the volume of the cone
Volume of a cone =1/3 πr²h
h = 11 inches - 6 inches
= 5 inches
r = 2.5 inches
Hence,
1/3 × π × 2.5² × 5
= 32.72 cubic inches
Therefore:
Volume of rocket = Volume of Cylinder + Volume of Cone
= 117.81 cubic inches + 32.72 cubic inches
= 150.53 cubic inches
Approximately to the nearest inch = 151 in³ or 151 cubic inches
Option A is correct
Write the equation of the line passing through the points (-7,9) and (7,5).
Answer:
[tex]y=-\frac{2}{7} x+7[/tex]
Step-by-step explanation:
First Solve For The Slope Using The Two Given Points!
M = Slope
M = [tex]\frac{y2-y1}{x2-x1}[/tex]
M = [tex]\frac{5-9}{7--7}[/tex] Two negative signs together makes addition!
M = [tex]\frac{-4}{14}[/tex] Move the negative sign (only if the fraction has a negative)
M = [tex]-\frac{4}{14}[/tex] Simplify
M = [tex]-\frac{2}{7}[/tex] Final Answer
Then see how many units the graph goes up = y-intercept

Use the side -splitter theorem to solve for x in the triangle below
Answer:
x = 30
Step-by-step explanation:
Side splitter theorem,
"If a line intersects two sides of a triangle and is parallel to the third side of the triangle, will divide the sides proportionally."
Therefore, ratio of the parts of two sides intersected will be proportional.
[tex]\frac{3}{15}= \frac{6}{x}[/tex]
[tex]x=\frac{6\times 15}{3}[/tex]
[tex]x=30[/tex]
Therefore, [tex]x=30[/tex] will be the answer.

write an exponential function in the form y = ab^x that goes through points (0,20) and (8,5120)
9514 1404 393
Answer:
y = 20·2^x
Step-by-step explanation:
Use the given points to write two equations, then solve for 'a' and 'b'.
20 = a·b^0 = a
5120 = a·b^8 = 20·b^8 ⇒ 256 = b^8
b = 256^(1/8) = 2
Your function is ...
y = 20·2^x
Evaluate.

No all ele we
0
Given:
Consider the given equation is:
[tex]y=-\dfrac{7}{2}x+\dfrac{11}{3}[/tex]
To find:
The slope of the line that is represented by the given equation.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is y-intercept.
We have,
[tex]y=-\dfrac{7}{2}x+\dfrac{11}{3}[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=-\dfrac{7}{2}[/tex]
Therefore, the slope of the given equation is [tex]-\dfrac{7}{2}[/tex].

Answer:
10x² + 14x - 48
Step-by-step explanation:
F: (5x)(2x) = 10x²
O: (5x)(6) = 30x
I: (-8)(2x) = -16x
L: (-8)(6) = -48
combine the two middle terms to get 14x
10x² + 14x - 48
The endpoints of are A(2, 3) and B(8, 1). The perpendicular bisector of is , and point C lies on . The length of is units. The coordinates of point C are . The slope of is . The possible coordinates of point D are and .
Answer:
The Coordinates of Point C are C(5,2)
The slope of CD is 3
The possible coordinates of point D(a,b) are (6, 5) and (4, -1)
Step-by-step explanation:
According to the Question,
Given, The end points of AB are A(2,3) and B(8,1). The perpendicular Bisector of AB is CD, and point C lies on AB. The length of the CD is √10 units.Now, Let The Coordinates of Point C are C( x , y ) .
Thus, C( x , y ) = ((8 +2) / 2 , ( 1 + 3 )/ 2 ) ⇒ (10/2 , 4/2) ⇒ (5 , 2)The Coordinates of Point C are C( x , y ) ⇒C(5, 2).
And, The slope of AB = (1 - 3)/(8 - 2) ⇒ -2/6 ⇔ -1/3 .
Thus, The slope of CD is -1/(The slope of AB) = -1/(-1/3) ⇔ 3.Let the coordinate of D be (a, b) then
⇒ √{ (b - 2)² +(a - 5)² } = √10
on squaring both sides we get,
⇒ a² - 10a + 25 + b² - 4b + 4 = 10
⇒ a² + b² - 10a - 4b = - 19 ⇔⇔ (Equation 1)
We Know, the slope of CD = 3
⇒Thus, (b - 2)/(a - 5) = 3
⇒ b - 2 = 3a - 15
⇒ b = 3a - 13 ⇔⇔ (Equation 2)
Putting value of Equation 2 into Equation 1, We get
⇒a² + (3a - 13)² - 10a - 4(3a - 13) = - 19
⇒a² + 9a² - 78a + 169 - 10a - 12a + 52 = - 19
⇒10a² - 100a + 240 = 0
⇒a² - 10a + 24 = 0
⇒(a - 4)(a - 6) = 0
⇒a = 4 or a = 6
Now,
When a = 4 , b = 3(4) - 13 ⇒ 12 - 13 ⇒ b = -1
When a = 6, b = 3(6) - 13 ⇒ 18 - 13 ⇒ b = 5
Therefore, the possible coordinates of point D(a,b) are (6, 5) and (4, -1).

LA=5x-5°
ZB = 3x + 13°
B
Answer:
x=9
Step-by-step explanation:
angle A =angle B (because they are corresponding angles)
5x-5=3x+13
5x-3x=13+5
2x=18
x=18/2
x=9
angle A=5x-5
=5*9-5
=45-5
=40
angle B=3x+13
=3*9+13
=27+13
=40
Answer:
A = B
5X-5 = 3X+13
5X-3X. =13+5

=40
ANGLE A=ANGLE B =40
Can someone find this angle?
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
d+ 2d + 60 = 180
3d = 180 - 60
3d = 120
d = 40
The angles are 40, 80, 60
