A hot air balloon is descending at a rate of 6.75 feet per second.
What is the change in the balloon's height after 3 seconds?
Answers
The hot air balloon will descend 20.25 feet per second.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a hot air balloon is descending at a rate of 6.75 feet per second. The height of the balloon after 3 seconds will be:-
Rate of change = Height / Time
6.75 = Height / 3
Height = 6.75 x 3 = 20.25 feet
Therefore, the hot air balloon will descend 20.25 feet per second.

Answer:
m = 2
Step-by-step explanation:
To find the slope, simply use this equation:
m = y2 - y1 / x2 - x1
Now we need to insert some points:
m = 10 - 0 / 11 - 6
m = 10/5
m = 2
Therefore, the slope of the line is 2.

Step-by-step explanation:
y
y=ax
where a is a constant of proportionality;
y=20, x=4
20=4a
a=20/4
a=5
y=5x
The constant of variation is 5
The constant of variation for the given relationship is 5.
What is Direct Variation?Direct variations are defined as the functions of the form y = kx, where k is a constant.
Here when y increases, x increases and if y decreases, x also decreases.
Given that,
y varies directly as x
So the equation will be of the form,
y = kx
Here k is the constant of variation.
Given, y is 20 when x is 4.
So, 20 = 4k
k = 20 / 4 = 5
Hence the constant of variation for the given relationship is 5.

Answers
Answer:
Distance of JK = 15 unit
Step-by-step explanation:
Given:
J(4,8)
K(-1,-2)
Find:
Distance of JK
Computation:
Distance = √(x₂-x₁)² + (y₂-y₁)²
Distance of JK = √(-1-4)² + (-2-8)²
Distance of JK = √25 + 100
Distance of JK = √125
Distance of JK = 15 unit

a) What percentage of forgings will be defective?
b) What is the maximum allowable value of σ that will permit no more than 1 in 100 defectives when the widths are normally distributed with μ = 0.9000 and σ (revised value)?
Answers
Answer:
a) 9.56%
b) 0.0019
Step-by-step explanation:
a) Find the z-scores.
z = (x − μ) / σ
z₁ = (-0.0050) / 0.0030
z₁ = -1.67
z₂ = (0.0050) / 0.0030
z₂ = 1.67
Find the probability using a chart or calculator.
P(Z < -1.67 or Z > 1.67) = 2 P(Z < -1.67)
P(Z < -1.67 or Z > 1.67) = 2 (0.0478)
P(Z < -1.67 or Z > 1.67) = 0.0956
b) Use a chart or calculator to find the z-score.
P(Z < -z or Z > z) = 0.01
P(Z < -z) = 0.005
z = 2.576
Find the standard deviation.
z = (x − μ) / σ
2.576 = (0.0050) / σ
σ = 0.0019

Complete question is;
Select all polynomial expressions that are equivalent to 6x⁴ + 4x³ – 7x² + 5x + 8.
A. 16x^(10)
B. 6x^(5) + 4x⁴ – 7x³ + 5x² + 8x
C. 6x⁴ + 4x³ - 7x² + 5x + 8
D. 8 + 5x + 7x² - 4x³ + 6x⁴
E. 8 + 5x – 7x² + 4x³ + 6x⁴
Answer:
Options C & E
C. 6x⁴ + 4x³ - 7x² + 5x + 8
E. 8 + 5x – 7x² + 4x³ + 6x⁴
Step-by-step explanation:
To find the polynomial expressions that are equivalent to 6x⁴ + 4x³ – 7x² + 5x + 8 simply means that both polynomials must have identical signs, identical number of terms and identical terms.
Now, by inspection of tall the options, we can see that options C & E are equivalent to the initially given polynomial.
For option C: 6x⁴ + 4x³ - 7x² + 5x + 8
This expression is the exact same thing as what was given in the question.
For option E: 8 + 5x – 7x² + 4x³ + 6x⁴
Rearranging this gives;
6x⁴ + 4x³ - 7x² + 5x + 8
Again this is exactly the same expression given to us in the question.
