Multiply. (2+3 √2)(1-3√2)
The product of the given multiplication (2 + 3√2) (1 - 3√2) is - (16 + 3√2).
Given the multiplication is,
(2 + 3√2) (1 - 3√2)
Simplifying the given multiplication we get,
= 2 (1 - 3√2) + 3√2 (1 - 3√2)
= 2 * 1 - 2 * 3√2 + 3√2 * 1 - 3√2 * 3√2
= 2 - 6√2 + 3√2 - 18
= (2 - 18) + (3 - 6) √2 [Separating the constant and coefficients of √2]
= - 16 - 3√2
= - (16 + 3√2)
Hence the product is - (16 + 3√2).

Blank 2 answer:
Answer:
1. 89 2. 91
Step-by-step explanation:
180-29-62=118-29=89
180--89=91
Answer:
91 and 89 degrees respectively
Step-by-step explanation:
Sooooo, the exterior angle of any angle in a triangle is equal to the sum of the 2 other adjacent interior angles in a triangle. Therefore, we just need to do 29+62, which is 91 degrees, so the Exterior angle is 91 degrees. Next, to find the last unknown angle of a triangle, we can take the sum of the 2 other interior angles and subtract it from 180. Doing this here, we get 180-91, which is 89 degrees.

If f is a differentiable function at a point 'a' and f′(a)=0 then which of the following is true. A. -f' (a) = lim h -->0 f(a)-f(a-h)/h. B. 1/2f' (a) = lim h -->0 f(a+2h)-f(a-h)/2h C. f' (a) = lim h -->0 f(a+2h)-f(a)/h. D. none of these
The correct option is B.
We know that if a function is differentiable at a point 'a', then it is also continuous at that point.
Option A is the formula for the one-sided derivative, which only holds if f'(a) exists and is finite. Since f'(a) is given to be non-zero, option A cannot be true.
Option C has a denominator of h, which means it is the formula for the one-sided derivative as h approaches 0. Again, since f'(a) is non-zero, option C cannot be true.
Option B is the formula for the two-sided derivative, which is valid even if function f'(a) is non-zero. Therefore, option B is true.

Evaluate the function at each specified value of the independent variable and simplify. g(y) = 7 - 3y
(a) g(0)
(b) g(7/3)
(c) g(s + 2)
The values of g(y) at the specified values of the independent variable are:
(a) g(0) = 7
(b) g(7/3) = 0
(c) g(s + 2) = 1 - 3s.
To evaluate the function g(y) at the specified values of the independent variable, we substitute the values of y into the expression for g(y) and simplify:
(a) g(0) = 7 - 3(0) = 7 - 0 = 7
(b) g(7/3) = 7 - 3(7/3) = 7 - 7 = 0
(c) g(s + 2) = 7 - 3(s + 2) = 7 - 3s - 6 = 1 - 3s
Therefore, the values of g(y) at the specified values of the independent variable are:
(a) g(0) = 7
(b) g(7/3) = 0
(c) g(s + 2) = 1 - 3s.

But it doesn't get matched with t.
So, (a) option cancelled.
In (b) part, let us take the value of n as 1.

Matched again! So, (c) part is the correct answer.
Let us take the value of n as 1. (For both option (d) and (e))

isiah determined that 5a2 is the gcf of the polynomial a3 – 25a2b5 – 35b4. is he correct? explain.
No, Isaiah is incorrect. The greatest common factor (GCF) of the polynomial a^3 - 25a^2b^5 - 35b^4 is not 5a^2.
To determine the GCF of a polynomial, we need to find the highest power of each variable that is common to all terms. In this case, the polynomial consists of three terms: a^3, -25a^2b^5, and -35b^4.
To find the GCF, we identify the highest power of each variable that appears in all terms. In this polynomial, the highest power of 'a' is a^3, and the highest power of 'b' is b^5. However, the coefficient -25 in the second term does not contain a common factor of 5 with the other terms. Therefore, 5a^2 is not the GCF of the polynomial.
To determine the GCF, we need to find the common factors among all terms. In this case, both 'a' and 'b' are common factors among all terms. The highest power of 'a' that appears in all terms is a^2, and the highest power of 'b' that appears in all terms is b^4. Thus, the GCF of the polynomial a^3 - 25a^2b^5 - 35b^4 is a^2b^4.
In summary, Isaiah is incorrect in identifying the GCF as 5a^2. The correct GCF of the polynomial a^3 - 25a^2b^5 - 35b^4 is a^2b^4.

Step-by-step explanation:
1) solve: -6(x - 3) = 54
2) solve: -7(x + 2) = 42
Answer:
x = - 6 and x = - 8
Step-by-step explanation:
(1)
- 6(x - 3) = 54 ( divide both sides by - 6 )
x - 3 = - 9 ( add 3 to both sides )
x = - 6
(2)
- 7(x + 2) = 42 ( divide both sides by - 7 )
x + 2 = - 6 ( subtract 2 from both sides )
x = - 8
P is the midpoint of NO and equidistant from MN and MO. If MN=8i + 3j and MO= 4i - 5j. Find MP
P is the midpoint of NO and equidistant from MN and MO. If MN=8i + 3j and MO= 4i - 5j.Thus, the value of MP is √850.
Given that P is the midpoint of NO and equidistant from MN and MO.
Also, MN=8i + 3j and MO= 4i - 5j. We need to find the value of MP.
There are two methods to solve the given question:Method 1:Using the midpoint formula - Let (x, y) be the coordinates of point P.
Then, the coordinates of N and O are (2x - 4i - 6j) and (2x + 4i - 2j), respectively. Now, since P is equidistant from MN and MO, we have:MP² = MN² -----(1)And, MP² = MO² -----(2)
Substituting the given values in (1) and (2), we get:(
x - 4)² + (y + 3)² = (x + 4)² + (y + 5)²
Solving the above equation, we get:x = -1/2, y = -1/2
Therefore, the coordinates of point P are (-1/2, -1/2).
Hence, MP = √[(4 - (-1/2))² + (5 - (-1/2))²] = √(17² + 21²) = √850
Method 2:Using the distance formula - Since P is equidistant from MN and MO, we have:
MP² = MN² -----(1)And, MP² = MO² -----(2)
Substituting the given values in (1) and (2), we get:
(x - 4)² + (y + 3)² = (4x - 8)² + (4x + 8)²
Solving the above equation, we get:x = -1/2, y = -1/2
Therefore, the coordinates of point P are (-1/2, -1/2).
Hence, MP = √[(4 - (-1/2))² + (5 - (-1/2))²] = √(17² + 21²) = √850.
Thus, the value of MP is √850.

Consider the probability distribution of the random variable X
X P(X)
0 0.1
1 0.2
2 0.3
3 ?
a. Find the missing (?) probability value
b. Find E(X).
c. Find Var(X) and x.
d. If Z = 1 + 2/3X, find E(Z), Var(Z) and z.
a. The missing probability value is 0.4.
b. E(X) = 1.4.
c. Var(X) = 0.56 and σx = 0.75.
d. E(Z) = 2.27, Var(Z) = 2.56, and σz = 1.60.
The given probability distribution of the random variable X shows the probabilities associated with each possible outcome. To find the missing probability value, we know that the sum of all probabilities must equal 1. Therefore, the missing probability can be calculated by subtracting the sum of the probabilities already given from 1. In this case, 0.1 + 0.2 + 0.3 = 0.6, so the missing probability value is 1 - 0.6 = 0.4.
To find the expected value or mean of X (E(X)), we multiply each value of X by its corresponding probability and then sum up the results. In this case, (0 * 0.1) + (1 * 0.2) + (2 * 0.3) + (3 * 0.4) = 0.4 + 0.2 + 0.6 + 1.2 = 1.4.
To calculate the variance (Var(X)) of X, we use the formula: Var(X) = Σ[(X - E(X))^2 * P(X)], where Σ denotes the sum over all values of X. The standard deviation (σx) is the square root of the variance. Using this formula, we find Var(X) = [(0 - 1.4)² * 0.1] + [(1 - 1.4)^2 * 0.2] + [(2 - 1.4)² * 0.3] + [(3 - 1.4)² * 0.4] = 0.56. Taking the square root, we get σx = √(0.56) ≈ 0.75.
Now, let's consider the new random variable Z = 1 + (2/3)X. To find E(Z), we substitute the values of X into the formula and calculate the expected value. E(Z) = 1 + (2/3)E(X) = 1 + (2/3) * 1.4 = 2.27.
To calculate Var(Z), we use the formula Var(Z) = (2/3)² * Var(X). Substituting the known values, Var(Z) = (2/3)² * 0.56 = 2.56.
Finally, the standard deviation of Z (σz) is the square root of Var(Z). Therefore, σz = √(2.56) = 1.60.
