Explanation:The given equation is a quadratic equation. In other words, it is written in the form ax² + bx + c = 0, where a ≠ 0.
[tex] \\ [/tex]
We will solve this equation using the quadratic equation, which is the following:
[tex] \sf x = \dfrac{- b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] \\ [/tex]
First, let's identify the value of the coefficients a, b, and c:
a = 1b = -14c = 74[tex] \\ [/tex]
Then, substitute these values into the quadratic formula:
[tex] \sf x= \dfrac{-(-14) \pm \sqrt{(-14)^2 - 4(1)(74)}}{2(1)} = \dfrac{14 \pm \sqrt{-100}}{2} [/tex]
[tex] \\ [/tex]
Simplify the expression knowing that [tex] \sf \sqrt{-1} = i [/tex], and keep in mind the following property:
[tex] \Large{\boxed{\sf \sqrt{ab} = \sqrt{a}\sqrt{b} }} [/tex]
[tex] \\ [/tex]
[tex] \sf x= \dfrac{14 \pm \sqrt{100 \times (-1) }}{2} = \dfrac{14 \pm \sqrt{100} \times \sqrt{-1}}{2} = \dfrac{14 \pm 10 \times i }{2} \\ \\ \implies \boxed{\boxed{\sf x= 7 \pm 5i}} [/tex]
[tex] \\ [/tex]
Therefore, the two complex conjugate roots of this equation are x = 7 + 5i and x = 7 - 5i.

A game is played with a spinner on a circle, like the minute hand on a clock. The circle is marked evenly from 0 to 100, so, for example, the 3:00 position corresponds to 25, the 6:00 position to 50 and so on. The player spins the spinner, and the resulting number is the number of seconds he or she is given to solve a word puzzle. If 100 players are randomly selected, what is the approximate probability that the average time these players will get to solve the puzzle is between 44 and 56 seconds
Answer:
P( 44 < X < 56 ) = 0.12
Step-by-step explanation:
Number of seconds one gets to solve the puzzle ( X )
E( X ) = 100 + 0 ) / 2 = 50
Var ( X ) = 833.3333
бx = √833.3333 = 28.868
Determine The approximate probability
P( 44 < X < 56 ) = Δ time given / number of players selected
P( 44 < X < 56 ) = (56 - 44) / 100
= 12 / 100 = 0.12

OD.
g(x) = -4f(x)
E
The transformation of f (x) exists g (x) = f (x) - 4.
What is meant by exponential functions?A mathematical function using the following formula is an exponential function: f (x) = an x. where x is a variable and an is a fixed amount known as the function's base. The transcendental number e, or roughly 2.71828, is the most often encountered exponential-function base.
A function that has a positive constant increased to a variable exponent, other than 1, is referred to as an exponential function. By solving at a certain input value, a function is assessed. When the beginning value and growth rate are known, an exponential model can be discovered.
We observed that:
f (0) = 2
For the function g (x) we have:
g (0) = -2
Therefore,
g (x) = f (x) - 4
Looking for intersection with axis and we have:
g (0) = f (0) - 4
g (0) = 2 - 4
g (0) = -2 (correct demonstration)
The transformation of f (x) is: A. g (x) = f (x) - 4
Therefore, the correct answer is option A. g (x) = f (x) - 4.
The complete question is;
Two exponential functions, f and g, are shown in the figure below, where g is a transformation of f.
Which of the rules given below shows the transformation of f?
A. g(x) = f(x) - 4
B. g(x) = f(x - 4)
C. g(x) = f(x) + 4

Find the total surface area of the net below
Therefore ,answering the offered question, we can state that the figure's surface area is SA = 2(9 11+11 9+11 * 11), which equals SA = 638 in2.
What precisely is surface area?Surface area is a measure of how much space an object's surface takes up overall. The total area of a three-dimensional shape's surroundings is its surface area. Surface area refers to the total surface area of a three-dimensional shape. You may compute the contact area of a cube with six square faces by adding together their individual areas. Alternatively, you can use the following formula to name the box's dimensions: Surfaces (SA) = 21 h + 2 lw + 2 hw. A tri shape's surface area is calculated as the total amount of space it occupies.
Here,
Front = rear = 11*11
top = bottom = 9*11
sides = 11*9;
SA= 2(911+119+1111)
SA=2(9999 +121)
SA = 2(319) (319)
SA = 638 in²
