Answer:
(x² - 9)(x² - 1)
Step-by-step explanation:
Using Quadratic trinomials
Factor x⁴ - 10x² + 9
Step 1: Find the two integers whose product of 9 and whose sum of -10
Product
-9 × -1 = 9
Sum
-9 + -1 = -10
Step 2: Use -1 and -9 to complete the factors
x⁴ - 10x² + 9 = (x² - 9)(x² - 1)
Step 3: Use the foil method to check the factors
(x² - 9)(x² - 1) = x⁴ - 1x² - 9x² + 9 = x⁴ - 10x² + 9
Some one please help and find the domain and range. If your not sure about your answer don’t give the answer unless your 100% sure.
Answer:
Domain x=1 and range is 0≤f(x)≤3
Step-by-step explanation:
Domain corresponds to the value of x and range corresponds to the value of y
Here we see the graph exists at x=1 so the domain is x=1 or simply 1 and the range is a range of values from 0 to 3 so we write it in the way
0≤f(x)≤3

The area of a rectangular wall of a barn is 12 square feet. Its length is 14 feet longer than the width. Find the length and width of the wall of the barn.
Answer:
w = 0.81 ft
l = 14.81 ft
Step-by-step explanation:
The equation of the area of a rectangle is given by:
[tex]A_{r}=l*w[/tex]
But we know that l=14+w and [tex]A_{r}=12 ft^{2}[/tex]
So we will have:
[tex]12=(14+w)*w=14w+w^{2}[/tex]
[tex]w^{2}+14w-12=0[/tex]
Solving this quadratic equation we have:
w = 0.81 ft
We just take the positive solution
So, the length will be l = 14 + 0.81 = 14.81 ft
I hope it helps you!
What is the slope of a line perpendicular to the line y=8x+1
The slope of a line perpendicular to the line y=8x+1 is -1/8.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The product of slopes of line are m₁m₂=-1
The equation of line is y=8x+1
m₁=8
We need to find m₂
8m₂=-1
m₂=-1/8
Hence, the slope of a line perpendicular to the line y=8x+1 is -1/8.

Which multiplication expression is equal to 5/6 divided 1/2 ?
A: 6/5 times 1/2
B: 5/6 times 1/2
C: 6/5 times 2/1
D: 5/6 times 2/1
Answer:
D
Step-by-step explanation:
Another way to divide fractions is to multiply by the reciprocal, which is basically the fraction with the denominator put on top and the numerator put on the bottom.
The reciprocal of 1/2 is 2/1, so the correct answer choice is D
Hope this helps! Good luck :)
The multiplication expression that is equal to 5/6 ÷ 1/2 is 5/6 times 2/1, which simplifies to 5/3.
Thus, option (D) is correct.
Given: 5/6 ÷ 1/2
To find the reciprocal of 1/2, invert the fraction, which means switching the numerator and denominator:
Reciprocal of 1/2 = 2/1
Now, multiply the first fraction (5/6) by the reciprocal (2/1):
= (5/6) × (2/1)
Multiplying the numerators and denominators:
= (5 × 2) / (6 × 1)
= 10/6
To simplify the fraction, divide the numerator and denominator by their greatest common divisor (GCD):
GCD(10, 6) = 2
= (10/2) / (6/2)
= 5/3
Therefore, the equivalent multiplication expression is5/6 times 2/1.

The greatest ocean depth of -35,836 feet (35,836 feet below sea level). An unmanned research submarine dives form sea level to that depth in 17 equal steps. At what depth is the submarine located after the first step?
Answer:
2,108 feets below sea level
Step-by-step explanation:
Given that:
Greatest depth = - 35,836 feets
Unmanned submarine dives to the depth in 17 equal steps
That is ; 17 equal steps was taken to reach a depth of 35,836 feets below sea level.
Depth of submarine after first step :
Depth per step :
Total depth / number of steps
35836 / 17
=2,108 feets below sea level.
Hence, Depth of submarine after first step = 2,108 feets below sea level.

1. Tara already knew 4 appetizer recipes before starting culinary school, and she will learn 3 new appetizer recipes during each week of school. Write an equation that shows the relationship between the number of weeks and the number of appetizer recipes.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the number of appetizer recipes she will learn during school
(c) Solve your linear equation to determine the number of recipes that Tara will know after 18 weeks in school
(d) Explain your answer to Part 1c.
Answer:
See below.
Step-by-step explanation:
(a)
Let w = number of weeks since she started culinary school.
Let r = number of recipes she knows at the end of week w.
(b)
Each week she learns 3 new recipes. In w weeks she learns 3w new recipes.
She already knew 4 recipes before starting school.
The equation is:
r = 3w + 4
(c)
After 18 weeks of school, w = 18.
r = 3w + 4
r = 3(18) + 4
r = 54 + 4
r = 58
(d)
After 18 weeks of school, she will know 58 recipes.
She knew 4 recipes before starting school. in 18 weeks of school she learned 18 * 3 = 54 recipes. Altogether, after 18 weeks of school, she knows 58 recipes.
A mountain climber at the top of the mountain 160 metres above ground level observes the angle of depression of the two cars parked on the road side at 60 degree (second car) and 30degree (first car) respectively. Find the distance : 1. from the base of the mountain to the first car, 2. from the base of the mountain to the second car and, 3. between the two cars.
Answer:
a. distance between the base of the mountain and the first car, d = 277 m
b. distance between the base of the mountain and the second car, s = 92 m
c. distance between the two cars = 185 m
Step-by-step explanation:
a. Since the angle of depression is 30°, the interior angle = (90 - 30)° = 60°
Let the distance between the base of the mountain and the first car be d, and height of the mountain = 160 m
tan 60° = d/160 m
d = tan 60° * 160 m
distance between the base of the mountain and the first car, d = 277 m
b. Since the angle of depression is 60°, the interior angle = (90 - 60)° = 30°
Let the distance between the base of the mountain and the second car be s, and height of the mountain = 160 m
tan 30° = s/160 m
s = tan 30° * 160 m
distance between the base of the mountain and the second car, s = 92 m
c. distance between the two cars = 277 - 92
distance between the two cars = 185 m

Answer:
$85Step-by-step explanation:
le the total cost be y
and the number of miles be x
the expression for the total can be modelled linearly as
y=mx+c
given that
c=$40
m=$0.75
for x==60miles
we can substitute into the expression to solve for y we have
y=0.75(60)+40
y=45+40
y=85
The cost to deliver at a distance of 60miles is $85
