The composition of function f ( x ) / g ( x ) = -x² + x - 1
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x⁴ - x³ + x²
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = -x²
Now , the composition of function is ( f/g ) ( x )
On simplifying , we get
( f/g ) ( x ) = f ( x ) / g ( x )
f ( x ) / g ( x ) = x⁴ - x³ + x² / -x²
f ( x ) / g ( x ) = -x² + x - 1
Hence , the function is A = -x² + x - 1

Answer:
y = -1x - 2/2
Step-by-step explanation:
Slope is -1
B = 2/-2
Answer:
y = x - 4
Step-by-Step Explanation:
Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.
Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1 (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).
Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):
y = mx + b
-2 = 1(2) + b
-2 = 2 + b
Subtract 2 from both sides to solve for b:
-2 - 2 = 2 - 2 + b
-4 = b
Therefore, the y-intercept (b) = -4.
Hence, the equation of the perpendicular line is: y = x - 4

(a) 2/3
(b) 3/2
(c) 25/36
(d) 12/13
Step-by-step explanation:
[tex]\mathsf{Given :\;\dfrac{{sec}^2\theta - co{sec}^2\theta}{{sec}^2\theta + co{sec}^2\theta}}[/tex]
[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{{sec}\theta = \dfrac{1}{cos\theta}}}}[/tex]
[tex]\bigstar\;\;\textsf{We know that : \large\boxed{\mathsf{co{sec}\theta = \dfrac{1}{sin\theta}}}}[/tex]
[tex]\mathsf{\implies \dfrac{\dfrac{1}{cos^2\theta} - \dfrac{1}{sin^2\theta}}{\dfrac{1}{cos^2\theta} + \dfrac{1}{sin^2\theta}}}[/tex]
[tex]\mathsf{\implies \dfrac{\dfrac{sin^2\theta - cos^2\theta}{sin^2\theta.cos^2\theta}}{\dfrac{sin^2\theta + cos^2\theta}{sin^2\theta.cos^2\theta}}}[/tex]
[tex]\mathsf{\implies \dfrac{sin^2\theta - cos^2\theta}{sin^2\theta + cos^2\theta}}[/tex]
Taking sin²θ common in both numerator & denominator, We get :

128 in exponential form
Answer:
2^12
Step-by-step explanation:
I know that 128 is 32 x 4, so 128 is 2^5 x 2 x 2 = 2^7. Thus,
128 x 32 = 2^5 x 2^7.
The last step is to realize that if two factors have the same base (in this case, both bases are 2), then you can add the exponents:
2^5 x 2^7 = 2^5+7= 2^12.
And that is in exponential form. So the final answer is
128 x 32 = 2^12
Answer:
[tex]128 \: \: is \: \: 32 \times 4, \\ \\ so 128 is {2}^{5} \times 2 \times 2 = {2}^{7} . \\ \\ Thus, 128 \times 32 = {2}^{5} \times {2}^{7} .[/tex]
Exercise #6: Demarco is trying to determine how many pennies he has without having to count
them. He first weighs 20 pennies and finds they have a total weight of 54 grams. He then weighs
all the pennies and finds they weigh a total of 918 grams.
(a) Determine how much a single penny
weighs, i.e. the grams per penny.
(b) Use your answer from (a) to determine
how many pennies Demarco has.
Step-by-step explanation:
20 pennies weigh 54 grams.
what is the weight of a single penny ?
well, 1/20 of the weight of the 20 pennies.
so,
54/20 = 27/10 = 2.7 grams
all his pennies weigh 918 grams.
how many pennies are there ?
as many as the times the weight of a single penny fit into the total weight.
so,
918 / 2.7 = 9180/27 = 340
he has 340 pennies.

Solve for x.
x+5
___ = 3/8
x+8
Answer:
the answer would be -16/5
Step-by-step explanation:
Answer:
[tex]x = - \frac{16}{5} [/tex]
Step-by-step explanation:
[tex] \frac{x + 5}{x + 8} = \frac{3}{8}[/tex]
8 (x + 5) = 3 (x + 8)
8x + 40 = 3x + 24
8x - 3x = 24 - 40
5x = -6
x = -16 ÷ 5
x = -16/5
1. Write the equation in slope intercept form that represents the line that passes through (-4, -3) and (-2, 1)?
Answer:
y = 2x + 5
Step-by-step explanation:
Finding the slope:
[tex]\frac{y2-y1}{x2-x1}\\[/tex]
= (1-(-3))/(-2-(-4))
= (1+3)/(-2+4)
= 4/2
= 2
Slope: 2
Substituting the slope into the formula 'y=mx+c':
y = 2x+c
Substituting any point (in this case, (-2,1)):
1 = 2(-2) + c
1 = -4 + c
c = 1 + 4
c = 5
Hence,
y = 2x + 5

Isha, a super excited candy crush user, has increased her points by 75% percents in a week. shes at 14000 points now. how many points did Isha have on candy crush last week?
If she has increased by 75% in a week to get 14000 points then we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.
175% * x = 14000
1.75x =14000 Divide both sides by 1.75
x= 8000
So she had 8000 points last week.
Check:
175% * 8000= 14000
1.75 * 8000 = 14000
14000 = 14000
Answer:
8,000 points
Step-by-step explanation:
x + 0.75x = 14,000 (the initial amount of points X plus 0.75x)
1.75x = 14000
x = 14000/1.75
x = 8,000
