prisim a and prisim b have the same volume. which could be the dimensions of prisim b?
Answer:
length = 4 feet
width = 4 feet
height = 10 feet
Step-by-step explanation:
8x4x5 = 160
4x4x10 = 160
Answer:
length = 4 feet
width = 4 feet
height = 10 feet
Step-by-step explanation:
First we must find the volume of prism A
Assuming that the prism is a rectangular prism we can easily calculate the volume by multiplying the length by the width by the height
So V = 8 * 4 * 5
8 * 4 = 32
32 * 5 = 160
Hence, the volume of prism a is 160ft²
The question states that the volume of prism A is the same as the volume of prism B. Given that information we want to find the possible dimensions of prism B such that volume of prism A = volume of prism B.
We can do this by find the volume of each answer choice ( again, assuming that their rectangular prism )
For the first answer choice
4 * 4 * 10 = 160
160 = 160 however lets check the other answer choices.
For the second answer choice:
5 * 4 * 7 = 140
140≠160 therefore the second answer choice is not correct
For the third answer choice
8 * 4 * 6 = 192
192 ≠ 160 therefore the third answer choice is not correct
For the fourth answer choice
I can't see the dimensions, however we already know that the answer is the first answer choice.

The Pythagorean Identity states that:
(sin x)2 + (cos x)2 = 1
Given sin 0 = 2/5, find cos 0.
cos O = ✓21/ [ ? ]
Simplify the fraction.
Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
What is the vertex of the graph of the quadratic function f(x) = x2 + 6x +10?
F (3,-1)
G(-3,-1)
H(-3,1)
J(3,1)
Answer:
(-3, 1) (Answer H)
Step-by-step explanation:
f(x) = x^2 + 6x +10 can be rewritten by "completing the square" as
f(x) = (x + 3)^2 + 1, and by comparing this to y = (x - h)^2 + k, we see that h is -3, k is 1, so the vertex, (h, k), is at (-3, 1) (Answer H)

I REALLY NEED HELP QUICK PLEASE!!!
Answer:
If the correction of 6 * 6X is accurate then I hope this is the answer.
Step-by-step explanation:
6(6x)+3x=3+3x+5
1. First multiply 6 by 6
36x+3x=3+3x+5
2. Then add 36X and 3X
39x=3+3x+5
3. After that add 3 and 5
39x=3x+8
4. Subtract 3x from both sides of the equation.
39x−3x=8
5. Subtract 3x from 39x
36x=8
6. Divide

Answer:
d = 17.58
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(8, 7, 14)
Substitute the values in the above equation and you will get
d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2
= √(64 + 49 + 196)
= √309

The function sin) = 2n - 5 represents the value of the nth term in a sequence. What is the sum of the 1st and 6th terms of the sequence?
Answer:
4
Step-by-step explanation:
Using the nth term formula
a₁ = 2(1) - 5 = 2 - 5 = - 3
a₆ = 2(6) - 5 = 12 - 5 = 7
Then
a₁ + a₆ = - 3 + 7 = 4
