Given:
The expression is:
[tex]2b^3+5[/tex]
To find:
The value of the given expression when [tex]b=3[/tex].
Solution:
We have,
[tex]2b^3+5[/tex]
Substituting [tex]b=3[/tex] in the above expression, we get
[tex]2b^3+5=2(3)^3+5[/tex]
[tex]2b^3+5=2(27)+5[/tex]
[tex]2b^3+5=54+5[/tex]
[tex]2b^3+5=59[/tex]
Therefore, the value of given expression at [tex]b=3[/tex] is 59.
Answer:
The answer is 59
Step-by-step explanation:
2b³ + 5, b = 3
2(3)³ + 5
2 × 27 + 5 = 59
Thus, The answer is 59

One fourth the sum of x and ten is identical to x minus 4."
Answers
Answer and Step-by-step explanation:
We are given the word format of an equation.
Let's right it out in numerical form.
[tex]\frac{1}{4} (x + 10) = x - 4[/tex]
The first part says One fourth the sum of x and 10
The sum of x and 10 would be shown as x + 10, and one fourth of that means that [tex]\frac{1}{4}[/tex] is multiplying (x + 10).
In this case, identical would mean equal to.
So, [tex]\frac{1}{4}[/tex](x + 10) would be = to something.
It says that it is identical to x minus 4 (x - 4).
[tex]\frac{1}{4} (x + 10) = x - 4[/tex] is the equation.

When two objects reach the same time-space coordinates, they generally collide with each other. How is this different from what waves do?
Answers
Answer:
Waves superimpose upon each other when they collide, while objects do not
Step-by-step explanation:
The main difference between the collision of waves and the collision of objects is simply the superposition principle.
When waves collide, they do not do so in the same way objects do. The superposition principle explains that waves can either collide in a constructive or destructive manner.
Case A: Waves colliding in a constructive manner
When waves collide in a constructive manner, this means that they are in phase, in simpler terms, it means that they have the same shape as they move through space-time. Constructive collision leads to a formation of a bigger wave with a higher amplitude. This is how stereo speakers operate. They produce louder sounds by releasing the same audio waves, causing them to superimpose upon each other.
Case B: Waves colliding in a destructive manner:
When waves are out of phase(i.e do not have the same shape as they move through space-time) and they collide, they try to cancel each other out, leading to a new wave with a weaker amplitude. This is how noise-cancelling headphones work. They emit an equal and opposite wave sound to the noise around your ears, thus cancelling it out.
The equation of the scatter plot trend line is y = -1700x + 32000 where y is the value of the car in dollars and x is the age of cars in years. Use the trend line equation to predict the value of a car after 7 years.
Answers
Answer:
20100
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Given equation
y = -1700x + 32000
Where x is the age of car and y is the value of the car.
Then value after 7 years can be calculated as follows,
y = -1700 (7) + 32000
y = -11900 + 32000
y = 20,100
So, the value of car after 7 years will be 20100.

A simple random sample from a population with a normal distribution of 103 body temperatures has x = 98.30°F and s = 0.61°F. Construct a 95% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
Answers
Answer:
(98.2884 ; 98.3116)
Step-by-step explanation:
Given :
x = 98.30°F and s = 0.61°F
Sample size. n = 103
Zcritical at 95% = 1.96
Using the confidence interval relation :
x ± margin of error
Margin of Error :
Zcritical * s/√n
1.96 * 0.61/√103 = 0.0116
Lower boundary = (98.30 - 0.0116) = 98.2884
Upper boundary = (98.30 + 0.0116) = 98.3116
(98.2884 ; 98.3116)

Answer:
area of hexagon = 600√3 m²
explanation:
apothem² = 20² - 10² = 400 - 100 = 300
apothem of hexagon = √300 = 10√3 m²
area of hexagon = 1/2(6 x 20)(10√3) = 600√3 m²
Answer:
Step-by-step explanation:
One way to find the area of the hexagon is to use the formula [tex]A=\frac{1}{2}ap[/tex], where p is the perimeter and a is the apothem (distance from the center to the midpoint of one side).
The problem says the side length is 20, so the perimeter is 6 x 20 = 120.
The apothem is the distance marked by the dotted line. The rectangles height is [tex]20\sqrt{3}[/tex], so the apothem is half of that, [tex]10\sqrt{3}[/tex].
The area is [tex]\frac{1}{2}\cdot 10\sqrt{3} \cdot 120=600\sqrt{3}[/tex]
