Answer:
Step-by-step explanation:
If you are given 3.14 · 1.5 · 1.5, you actually have 3.14 · 1.5²
If you match this up to the area-of-a-circle formula A = πr²
you can see right away that r = 1.5. If r = 1.5, d = 2(1.5) = 3.0
I do not quite understand what you were trying to present in your
"And the other is the area 3.14•3
2) 3.14•1.25" so am unable to help you with it.
To find the diameter and radius of a circle, divide the given circumference by 3.14 to find the diameter, and then divide the diameter by 2 to find the radius. To calculate the area, use the formula A = πr², where π is approximately 3.14 and r is the radius of the circle.
Explanation:To find the diameter and radius of a circle, we need to understand the formulas and calculations involved. The diameter is the distance across the circle passing through the center, and it is twice the length of the radius. The radius is the distance from the center of the circle to any point on its edge.
Finding the Diameter and Radius:
To find the diameter, you need to divide the given circumference by 3.14. For example, to find the diameter of 3.14 • 1.5 • 1.5, you would divide this value by 3.14. To find the radius, you divide the diameter by 2. For example, if the diameter is 6, then the radius is half of that, which is 3.So, depending on the given values, you can use the formulas mentioned above to solve for the diameter and radius of a circle.
Calculating the Area:
To calculate the area of a circle, you need to use the formula A = πr², where π is approximately 3.14 and r is the radius of the circle. Substitute the given value of the radius into the formula and solve for the area. For example, if the radius is 3, then the area would be 3.14 • 3².Using the formulas and steps above, you can find the diameter, radius, and area of a circle based on the given values.
What is the product of (2x^2+4x-2) and (3x+6)
Answer:
6x³ + 24x² + 18x - 12
Step-by-step explanation:
We require the product
(2x² + 4x - 2)(3x + 6)
Each term in the second factor is multiplied by each term in the first factor, that is
2x²(3x + 6) + 4x(3x + 6) - 2(3x + 6) ← distribute all parenthesis
= 6x³ + 12x² + 12x² + 24x - 6x - 12 ← collect like terms
= 6x³ + 24x² + 18x - 12

square pyramid has a volume of 20 cubic feet and a base length of 5 feet. What is it's height?
Answer:
2.4 ft = height
Step-by-step explanation:
The formula for the volume of a pyramid is V = (1/3)(base area)(height).
Here V = 20 ft² = (1/3)(base area)(height).
Since the base area is (5 ft)², or 25 ft², 20 ft² = (1/3)(25 ft²)(height),
(height) = (20 ft³) / ( [25/3] ft², or 60 ft³ / (25 ft²) = 2.4 ft = height

What is the range of the function f(x) = 3x2 + 6x – 8?
Answer: C... {y|y ≥ -1}
Step-by-step explanation:
f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.
in vertex form (h, k) = (-1, -11)
This meaning the range ={y|y ≥ -11}

Given the points A(-3,-4) and B(2,0), point P(-1,-12/5) partitions AB in the ratio ...
A. 1:3
B. 2:1
C. 2:3
D. 3:2
Answer:
A 1:3
Step-by-step explanation:
Point P(-1, -12/5) partitions the line segment AB in the ratio of 2:1, which is calculated using the section formula in coordinate geometry.
To determine the ratio at which point P partitions AB, we can use the concept of section formula in coordinate geometry. The section formula states that if a point P(x, y) divides the line segment AB in the ratio m:n, then its coordinates are given by:
[tex]\[ x = \frac{mx_2 + nx_1}{m + n} \quad \text{and} \quad y = \frac{my_2 + ny_1}{m + n} \][/tex]
Substituting the given coordinates of A(-3, -4), B(2, 0), and P(-1, -12/5), we can form two equations with the unknowns m and n. Solving for m and n will give us the required ratio.
[tex]\[ -1 = \frac{m \cdot 2 + n \cdot (-3)}{m + n} \text{ and } (-\frac{12}{5}) = \frac{m \cdot 0 + n \cdot (-4)}{m + n} \][/tex]
Solving the equations, we find m = 2 and n = 1, meaning P divides AB in the ratio of 2:1, which is option B.

A and B are independent events if...
Answer:
(C) The probability of buying bread and cheese is 0.12
Step-by-step explanation:
P(Event A) = 0.6
P(Event B) = 0.2
If Event A and Event B are independent,
Then P(Event A and Event B) = 0.6 x 0.2 = 0.12
A and B are independent events if:
C. The probability of buying bread and cheese is : 0.12
Step-by-step explanation:Two events A and B are said to be independent.
if P(A∩B)=P(A)×P(B)
where P denote the probability of an event.
Here,
Event A= A shopper buys bread
and Event B=A shopper buys cheese
Also we have:
P(A)= 0.60 and P(B)= 0.20
If A and B are independent events then,
P(A∩B)=0.60×0.20
i.e.
P(A∩B)=0.12
i.e.If A and B are independent then the probability of buying bread and cheese is: 0.12
Also we know that:
P(A∪B)=P(A)+P(B)-P(A∩B)
If A and B are independent then,
P(A∪B)=0.60+0.20-0.12
i.e.
P(A∪B)=0.68
If A and B are independent then the probability of buying bread or cheese is: 0.68

3(17x – 6.5) = 108. What does x equal in this equation
Answer:
x=2.5
Step-by-step explanation:
First, you need to expand the brackets.
51x-19.5=108
Next, you need to add 19.5 to both sides giving:
51x=127.5
Then finally, you need to divide both sides by 51.
x =2.5
x equal to 2.5 in this equation
What does x equal in this equation?An algebraic equation is a mathematical statement that contains two or more algebraic expressions that are set equal to each other. The algebraic expressions can contain variables, constants, and operators.
We have:
3(17x – 6.5) = 108
We can solve for the value of x as follow:
3(17x – 6.5) = 108
17x(3) - 6.5(3) = 108
51x - 19.5 = 108
51x = 108 + 19.5
51x = 127.5
x = 127.5/51
x = 2.5
Therefore, x equal to 2.5 in this equation

In 1981, the Australian humpback whale population was 350 and has increased at a rate of 14% each year since then.)
Write the equation for a function to that you could use to predict how many whales there would be in the year 2000: P(t) = _______
There would be about _______ humpback whales in the year 2018(round to the nearest whole number)
Answer:
In 1981, the Australian humpback whale population was 350
Po = Initial population = 350
rate of increase = 14% annually
P(t) = Po*(1.14)^t
P(t) = 350*(1.14)^t
Where
t = number of years that have passed since 1981
Year 2000
2000 - 1981 = 19 years
P(19) = 350*(1.14)^19
P(19) = 350*12.055
P(19) = 4219.49
P(19) ≈ 4219
Year 2018
2018 - 1981 = 37 years
P(37) = 350*(1.14)^37
P(37) = 350*127.4909
P(37) = 44621.84
P(37) ≈ 44622
There would be about 44622 humpback whales in the year 2018
Final answer:
To predict the Australian humpback whale population, an exponential growth model is used with equation P(t) = 350 [tex]imes (1 + 0.14)^t.[/tex] By substituting t with the number of years since 1981, we can estimate the population for any given year.
Explanation:
To write the equation for a function you could use to predict the number of humpback whales, we can use an exponential growth model because the population increases by a constant percentage rate each year. The general form of an exponential growth model is [tex]P(t) = P0 imes (1 + r)t,[/tex]where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and t is the number of years since the initial time.
Given that the initial population in 1981 was 350 whales and the growth rate is 14% or 0.14, and taking t to be the number of years since 1981, the function to predict the number of whales in year t is:
[tex]P(t) = 350 imes (1 + 0.14)t[/tex]
For the number of whales in the year 2000, we substitute t with 19 (since 2000-1981=19), and for the year 2018 it would be 37 (since 2018-1981=37).
To predict the number of humpback whales in the year 2018, we use the function with t=37:
[tex]P(37) = 350 imes (1 + 0.14)37[/tex]
Calculating this, the result is rounded to the nearest whole number giving us the approximate whale population in 2018.
