KEEP IN MIND ----> *Square root of a number is a value, which on multiplication by itself gives the original number. The square root is an inverse method of squaring a number.*
Alright so the first equation C^2 - 49 = 0
Step 1 : Add 49 to both sides
C^2 - 49 + 49 = 0 + 49
C^2 = 49
Step 2 : Take the square root
(squ root) C^2 = (squ root)49
C = +/- (squ root) 49
Final answer ---> C = 7 OR C = -7
2.) 4S^2 - 100 = 0
Step 1 : Add 100 to both sides
4S^2 - 100 + 100 = 0 + 100
4S^2 = 100
Step 2 : Divide both sides by 4
4S^2/4 = 100/4
S^2 = 25
Step 3 : Take the square root
(squ root) S^2 = (squ root) 25
S = +/- (squ root) 25
Final answer ---> S = 5 OR S = -5
3.) 9x^2 = 324
Step 1: Divide both sides by 9.
9x^2/9 = 324/9
x^2 = 36
Step 2: Take the square root
squ root) x^2 = (squ root) 36
x = +/- (squ root) 36
Final answer ---> x = 6 OR x = -6
Rodolfo le da una vuelta a la manzana en 4 minutos; Ricardo, en 5 minutos y Rena to, en 6 minutos. ¿En cuánto tiempo existirán si empiezan a hacer el recorrido desde el mismo punto?
Rodolfo, Rena y Ricardo se encuentran después de 6 minutos en la salida si todos comienzan su viaje desde el mismo punto.
Rodolfo tarda unos 4 minutos en dar la vuelta a la manzana.
Ricardo tarda 5 minutos en dar la vuelta a la manzana.
Rena tarda 6 minutos en dar la vuelta a la manzana.
Digamos que los tres comienzan el viaje desde el mismo punto A.
Rena tarda 6 minutos, Ricardo tarda un minuto menos que Rena y Rodolfo tarda 2 minutos menos que Rena.
Por lo tanto,
Rena es la que más tarda en dar la vuelta a la manzana y será la última en salir.
Por lo tanto, Rodolfo, Ricardo y Rena se encontrarán después de 6 minutos en la salida.
Todas se reúnen después de 6 minutos en la salida.

f(x) = -x² - 8x - 16; Find ƒ(-3)
f(-3) = -1
Step-by-step explanation:We can find an unknown y-value by plugging an x-value into a given function.
Function Notation
Before we answer this question, we need to understand the notation of the equation. In function notation, the equation is given in terms of f(x).
"f(x)" represents the y-value of a function at the point "x".For example, f(-3) represents the value of y when x = -3.
Finding f(3)
As stated above, to find f(-3) we need to plug -3 in for x. *Remember to use PEMDAS when solving.* This creates the new equation:
f(-3) = -(-3)² - 8(-3) - 16Then, distribute the exponent.
f(-3) = -9 - 8(-3) - 16Next, multiply.
f(-3) = -9 - (-24) - 16Distribute the negative.
f(-3) = -9 + 24 - 16Finally, add the remaining terms.
f(-3) = -1This means that when x = -3, y or f(-3) = -1.
Rory has 3 pounds of ground turkey to make meatballs.He uses 3/8 pound per to make 6 meatballs. How many 1/8 pound meatballs can Rory make with the remaining turkey?
He can make 2 meat balls from the remaining turkey.
Total pounds of ground turkey available = 3 pounds.
Turkey used to make 6 meat ball = 3 / 8 of 3 pounds = 9 / 8 pounds
Turkey used to make 1 meat ball = 9 / 8 ÷ 6 = 3 / 16
1 / 8 meat = 1/ 8 of 3 = 3 / 8 pound of meat.
Number of meatballs made = 3 / 8 × 16 / 3 = 2
Therefore, he can make 2 meat balls from the remaining turkey.

Step-by-step explanation:
i think dis right
Answer:
see explanation
Step-by-step explanation:
using the following expansions
a² + 2ab + b² = (a + b)²
a² - 2ab + b² = (a - b)²
1
x² - 12x + 36
with a = x and b = 6 , then
x² - 12x + 36 = x² - 2(x)(6) + 6² = (x - 6)²
2
x² + 22x + 121
with a = x and b = 11 , then
x² + 22x + 121 = x² + 2(x)(11) + 11² = (x + 11)²
3
x² - 8xy + 16y²
with a = x and b = 4y , then
x² - 8xy + 16y² = x² - 2(x)(4y) + 16y² = (x - 4y)²
4
25x² - 10xy + y²
with a = 5x and b = y , then
25x² - 10xy + y² = 25x² - 2(5x)(y) + y² = (5x - y)²
Evaluate the indefinite integral. (use c for the constant of integration.) x5 1 x12 dx
The evaluation of the given indefinite integral is (1/8)Tan⁻¹(x⁸) + C.
What is indefinite integral?A function that performs the antiderivative of another function is known as an indefinite integral. It can be represented visually as an integral symbol, a function, and finally a dx. A differentiable function F whose derivative is equal to the original function f is referred to as an antiderivative, inverse derivative, primitive function, primitive integral, or indefinite integral of a function f in calculus.So,
∫[x⁷ / (1 + x¹⁶)]dx = ∫[x⁷ / (1 + (x⁸)²]dxNow, u = x⁸. Then, du = 8x⁷dx. So, x⁷dx = (1/8)du.So, we obtain: (1/8)∫[du / (1 + u²)] = (1/8)Tan⁻¹u + C = (1/8)Tan⁻¹(x⁸) + CTherefore, the evaluation of the given indefinite integral is (1/8)Tan⁻¹(x⁸)+C.

Given the binary number 1011, what is the next consecutive binary value? (what happens when you add 1 to 1011)? explain how you arrived at your answer.
The next consecutive binary value of 1011 = 1100
Binary numbers only consist of two digits: 0 and 1. So there are some specific rules for addition in binary. They are:
0 + 0 = 00 + 1 = 11 + 1 = 10(read as one zero and corresponds to the binary value of 2)1 +1 + 1 = 11 (read as one one one and corresponds to the binary value of 3)Here 1011 is a binary number and to find the its next consecutive binary value, we have to add 1 to 1011.
i.e., 1 0 1 1 +
1
------------------
1 1 0 0
The 0 in the one's place is got by adding 1 + 1 = 10 and 1 is supposed to be a carry to the ten's place. The 0 in the ten's place is got from adding this carry 1 and 1, which again gives 10 and 1 is carry to next place. Now 0 + 1 = 1 and finally we get, 1011 + 1 = 1100.
