The function
has the same amplitude as the function y = cos(x – 4) + 1.

The function
is a translation of the parent cosine function.

Answers

Answer: the function y = cos(2x) - 2 and the function y = cos(x) - 3

Step-by-step explanation: just took it

Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].

Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element  [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -

The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:

[tex]y=cos2(x)-2[/tex][tex]y=cos(x)-3[/tex]

Therefore, function [tex]y=cos2(x)-2[/tex] , and function [tex]y=cos(x)-3[/tex].

Identify the slope and y-intercept from the following equation.

Answers

Answer:

The slope is 2/5 and the y intercept is -4

Step-by-step explanation:

The slope is always the coefficient to x

Answer:

slope = [tex]\frac{2}{5}[/tex] , y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form

with slope m = [tex]\frac{2}{5}[/tex] and y- intercept c = - 4

Problem 10

Answer: 80 degrees

Work Shown: 80-0 = 80

You subtract the values on the protractor where the two angle arms line up.

============================================

Problem 11

Answer: 45 degrees

Work Shown: 45-0 = 45

Same idea as problem 10

============================================

Problem 12

Answer: 83 degrees

Work Shown: 128-45 = 83

Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.

============================================

Problem 13

Answer:  35 degrees

Explanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.

One solution to a quadratic equation is x = 1 + 8i. What is the other solution?

Answers

We'll assume the quadratic equation has real coefficients

Answer:

The other solution is x=1-8i.

Step-by-step explanation:

The Complex Conjugate Root Theorem

if P(x) is a polynomial in x with real coefficients, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).

The question does not specify if the quadratic equation has real coefficients, but we will assume that.

Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.

Answer:

the answer would be x= 1-8i

f(x) = 8x - 11

f(9) =

Answers

Answer:

61

Step-by-step explanation:

hi! we can start off by plugging in the number 9 for x in the equation.

f(x)=8x-11)

f(9)= 8(9)-11

= 72-11

=61

hope this helps.

The answer is 61.

Replace the x in the equation with the nine. F(9) = 8(9) - 11

Now first multiply 8 x 9 which is 72

Now you have F(9) = 72 - 11
Subtract the two numbers.

F(9) = 61

(9+2).0 = 0
