Answers
The equation that could be used to determine the volume of Box B is (B = 14.325cm³ - 5.61cm³) and the volume of Box B is 8.715cm³.
This question is incomplete, the complete question is:
The sum of the volume of two rectangular prisms, box a and box b are 14.325cm cubed. Box a has a volume of 5.61cm.
a. Let B represent the volume of Box B in cubic centimeters. Write an equation that could be used to determine the volume of Box B.
b. Solve the equation to determine the volume of Box B
What is volume?Volume is simply the amount of space that is enclosed within a container.
Given that;
Sum of the volume of two rectangular prisms A&B = 14.325cm³Volume of Box A = 5.61cm³a)
Let B represent the volume of Box B in cubic centimeters. The equation that could be used to determine the volume of Box B will be;
Sum of the volume of two rectangular prisms A&B = Volume of Box A + Volume of Box B
14.325cm³ = 5.61cm³ + B
B = 14.325cm³ - 5.61cm³
Hence, The equation that could be used to determine the volume of Box B is B = 14.325cm³ - 5.61cm³
b)
To determine the volume of Box B, we solve the equation.
B = 14.325cm³ - 5.61cm³
B = 8.715cm³
Hence, the volume of Box B is 8.715cm³.

Answer:

Step-by-step explanation:
just find the equal difference of y values.
Step-by-step explanation:
to add to the explanation :
an arithmetic sequence is defined as
an = an-1 + d
so, every term of the sequence is created by adding the same constant d (the common difference) to the previous term.
therefore, you find the common difference by finding the difference of 2 sequential terms.
like here e.g.
a3 = 38
a4 = 53
53 - 38 = 15
bingo !
and to verify that it truly is an arithmetic sequence, we can quickly also check the differences between the other pairs. yes, they are all 15.
be prepared for a trap like
1 8
2 23
3 38
5 68
notice the sudden jump in x ? suddenly x is increased by 2.
that just means we compare
an and an-2 instead of an-1.
so, how is related to an-2 ?
an = an-1 + d = (an-2 + d) + d = an-2 + 2d
and so we would get
a3 = 38
a5 = 68
a5 - a3 = 2d = 30
d = 15
so, don't get confused by such jumps or gaps.

What is the y-intercept of f(x) = 3x 2? a. (9,0) b. (0,9) c. (0,-9) d. (9,-9)
Answers
Answer:
f(x) = 3x + 9: y - intercept is option c. (0,-9)
f(x) = 3x - 9: y - intercept is option b. (0, 9)
Step-by-step explanation:
option a and d cant be correct since y = 0 in those answer when the y - intercept is when x = 0
If the function f(x) = 3x + 9
than x = 0
f(x) = 3(0) + 9
f(x) = 0 + 9
f(x) = 9
x = 0 and y = 9 (0, 9)
If the function f(x) = 3x - 9
than x = 0
f(x) = 3(0) - 9
f(x) = 0 - 9
f(x) = -9
x = 0 and y = -9 (0, -9)
F(X)=3x-9: y intercept is option B

b. (2 - 2i√3)⁴ in rectangular form is -128 + 128√3
To answer the question, we need to know what complex numbers are
What are complex numbers?Complex numbers are numbers of the form z = x + iy
a. Complex numbers in polar formComplex numbers in polar form z = r(cosθ + isinθ) where
r = √(x² + y²) and θ = tan⁻¹(y/x)Given that z = (2 - 2i√3)⁴ =
So,
x = 2 and y = -2√3So, converting to polar form
r = √(x² + y²)
= √[2² + (-2√3)²]
= √[4 + 4(3)]
= √[4 + 12]
= √16
= 4
θ = tan⁻¹(y/x)
θ = tan⁻¹(-2√3/2)
θ = tan⁻¹(-√3)
θ = -π/3
So, z = r(cosθ + isinθ)
= 4(cos(-π/3) + isin(-π/3))
Powers of complex numbersA complex number z raised to power n is zⁿ = rⁿ(cosnθ + isin(nθ)]
z⁴ = (2 - 2i√3)⁴
= r⁴(cos4θ + isin4θ)
= 4⁴(cos(4 × -π/3) + isin(4 × -π/3))
= 256(cos(-4π/3) + isin(-4π/3))
= 256cis(-4π/3)
(2 - 2i√3)⁴ in polar form is 256(cos(-4π/3) + isin(-4π/3)) = 256cis(-4π/3)
b. Complex numbers in rectangular formThe complex number z = r(cosθ + isinθ) in rectangular form is z = x + iy where
x = rcosθ and y = rsinθGiven that z⁴ = 256(cos(-4π/3) + isin(-4π/3)) in rectangular form,
x = rcosθ
= 256(cos(-4π/3)
= 256cos(-4 × 60°)
= 256cos(-240)
= 256cos(240)
= 256 × -1/2
= -128
y = rsinθ
= 256sin(-4π/3)
= 256sin(-4 × 60°)
= 256sin(-240)
= -256sin240
= -256 × -√3/2
= 128√3
So, z⁴ = x + iy
= -128 + 128√3
So, (2 - 2i√3)⁴ in rectangular form is -128 + 128√3
