describe how to use special product patterns to find 21^2
Answer:
21 x 21 = 441
Step-by-step explanation:
Whenever there is an exponent that is the many times you multiply the base by itself to.
Power is the result of multiplying two numbers together. The value of 21^2 is 441.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.
21^2
= 21²
= 21 × 21
= 441
Hence, the value of 21^2 is 441.

Express the product of (2x + 3) and (x - 5)
Answer:
Here is the answer......
Answer:
2x² - 7x - 15
Step-by-step explanation:
Given
(2x + 3)(x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x - 5) + 3(x - 5) ← distribute parenthesis
= 2x² - 10x + 3x - 15 ← collect like terms
= 2x² - 7x - 15

Write a quadratic function f whose zeros are 3 and 10
Answer:
[tex]f(x) = {x}^{2} - 13x + 30[/tex]
Step-by-step explanation:
A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).
f(x) = (x-3)(x-10)
f(x) = x^2 - 13x + 30
Write the number that is the solution of this equation. 8x- 10 = 70 *
8x - 10 = 70
8x = 70 + 10
8x = 80 / : 8
x = 10

i hope this helps you!
Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!
I hope this helps.

The number $y$ of calories burned after $x$ minutes of kayaking is represented by the linear function $y=4.5x$ . The graph shows the number of calories burned by hiking.
You perform each activity for 45 minutes. How many total calories do you burn?
Answer:
202.5 calories
Step-by-step explanation:
y = 4.5x where y is the calories burned and x is the minutes
Let x = 45 minutes
y = 4.5 * 45
y =202.5 calories
Answer:
The average person burns 375 – 475 calories per hour kayaking.
The number of calories burned kayaking depends on your weight, the distance and speed you kayak, and difficulty of terrain. A 200-pound (90.8kg) person will burn 477 calories per hour kayaking with moderate effort. A 150-pound person will burn 358 calories per hour with the same activity.

Answer:
361/50 or 7[tex]\frac{11}{50}[/tex]
Step-by-step explanation:
7.22 = 722/100 = 361/50 = 7 11/50
The number 7.22 can be written using the fraction 722/100 which is equal to 361/50 when reduced to lowest terms.
It is also equal to 7 11/50 when written as a mixed number.
You can use the following approximate value(s) for this number:

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

Answer:
I think the answer is 200 feet
Step-by-step explanation:
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A right-angle triangle has sides with lengths 200 ft and 200 ft.
By Pythagoras theorem, we have
H² = P² + B²
H² = 200² + 200²
H² = 40000 + 40000
H² = 80000
H = 200√2
H = 282.84 ft
Alma is going to walk through the park from Point A to Point B is 282.84 ft.
