The temperature increase in degrees Fahrenheit that is equivalent to a temperature increase by 10 degrees Celsius is 50 degree Fahrenheit.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
As we know:
F = 32 + 1.8C
We have C = 10 degree Celsius
F = 32 + 1.8×10
F = 50 degree Fahrenheit
Thus, the temperature increase in degrees Fahrenheit that is equivalent to a temperature increase by 10 degrees Celsius is 50 degree Fahrenheit.

please help me understand this!! TRIG
Answer:
EG ≈ 6
Step-by-step explanation:
sin∅ = opposite over hypotenuse
Since we have a right triangle, we can use trig to solve for the missing values:
∅ = 49°
GE = unknown
FE (hypotenuse) = 8
sin49° = x/8
x = 8sin49°
x = 6.03768
x ≈ 6

Online you
could buy 5 used CD's for $20.70.
Which place has a lower unit price?
Answer:
Answer: Online
Step-by-step explanation:
Find the unit price
(multiply 12.51 and 20.70 by 100 to make it easier to divide)

Answer:
22
Step-by-step explanation:
96° = (6x - 36)° (alternate exterior angles theorem)
Solve for x using the equation.
96 = 6x - 36
Add 36 to each side
96 + 36 = 6x - 36 + 36
132 = 6x
Divide both sides by 6
132/6 = 6x/6

What is a function?Function is a type of relation, or rule, that maps one input to specific single output. An equation is an expression that shows the relationship between two or more numbers and variables.
The absolute value function always gives a positive result, which is;
| - a | = | a | = a
Given that | 12 - 3 |/4 - | 23 -42 | /8
| 12 - 3 |/4 - | 23 -42 | /8
| 15 |/4 - | -19 | /8
= 15/4 - 19/8
= 30/8 - 19/8

Which expression is equivalent to 4x^2Sqrt5x^4 • 3sqrt5x^8, if x ≠ 0?
A) 12x^10sqrt5
B) 60x^8
C) 35x^18
D) 7x^10sqrt5
the equivalent expression is:
60*x^8
Which is option B.
How to get the equivalent expression?
Here we start with:
4*x^2*√(5x^4)*3*√(5x^8)
Remember that square roots are distributive, then we can just write:
(4*3)*(x^2)*(√(5x^4)*√(5x^8))
12*x^2*√(25x^12)
Now, the square root can now be solved
12*x^2*√(25x^12) = 12*x^2*5*x^6
= (12*6)*(x^2*x^6)
Remember that in the right side, the exponents just add, then we get:
(12*6)*(x^2*x^6) = 60*x^{2 + 6} = 60*x^8
Then the equivalent expression is:
60*x^8
Which is option B.

find the inverse of y=4-x/x
Answer:
[tex]f^{-1} (x)[/tex]=[tex]\frac{4}{1+x}[/tex]
Step-by-step explanation:
The first step is to switch y for x and x for y so the equation will look like
x=[tex]\frac{4-y}{y}[/tex]
the next thing you do is isolate y so you have to multiply y to both sides to get
[tex]xy=4-y[/tex] now you got to add y to both sides which would get you
xy+y=4
since xy and y share a y value you have to try and factor out y which would get you
y(x+1)=4
the final step is to divide x+1 on both sides
y[tex]\frac{(x+1)}{x+1}[/tex]=[tex]\frac{4}{x+1}[/tex]
which since x+1 and x+1 crosses each other out we are left with
y=[tex]\frac{4}{1+x}[/tex]

The number of stars in the observable universe is; 3.033 × 10¹⁴
Since there are about 3 × 1011 stars in our galaxy; we can rewrite that to be;
3033 stars or3033 stars or3.033 × 10³ stars in our galaxy.However, there are about 100 billion galaxies in the observable universe.
We can rewrite that in scientific notation form so that we have;
100 × 10⁹ or 100 × 10⁹ or 10¹¹ galaxies in the observable universe.Ultimately, since our galaxy is one of the 10¹¹ observable galaxies in the universe; the number of stars in the observable universe is;
3.033 × 10³ × 10¹¹By the laws of indices;
3.033 × 10¹⁴.Therefore, the number of stars in the observable universe is; 3.033 × 10¹⁴.

2.1 Factoring: 25m2-36
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.

A child shot a toy rocket into the air from their playhouse which stood 5 ft above the ground. The rocket rose to 50 ft above the ground and landed on the ground 3.4 seconds later. The path of the toy rocket could be modeled by a quadratic function, , where h is the height of the toy rocket in feet after t seconds. ⦁ What is the practical domain of the function? ⦁ What is the practical range of the function? ⦁ How would the theoretical domain and range of the function differ from the practical domain and range of the situation?
Answer:
a. 0 ≤ t ≤ 3.4 s. b. 0 ≤ y ≤ 50 ft. c. i. -∞ ≤ t ≤ +∞. ii. -∞ ≤ y ≤ 50
Step-by-step explanation:
a. What is the practical domain of the function?
Since the toy rocket lands on the ground 3.4 seconds later, if the time it starts to fly in the air is time t = 0 and the time it lands is time t = 3.4 s, the practical domain of the function is 0 ≤ t ≤ 3.4 s.
b. What is the practical range of the function?
Since the rocket reaches a maximum height of 50 ft, if the maximum height of the toy rocket is y = 50 ft and it lands on the ground at y = 0, the practical range of the function is 0 ≤ y ≤ 50 ft.
c. How would the theoretical domain and range of the function differ from the practical domain and range of the situation?
i. The theoretical values of t is from is from t = -∞ to t = +∞. So, the theoretical domain is -∞ ≤ t ≤ +∞.
ii. Since the maximum value of the function is y = 50, and it also decreases to y = -∞. So, the theoretical domain is from y = -∞ to y = 50. So, the theoretical range is -∞ ≤ y ≤ 50
A contractor purchases ceramic tile to remodel a kitchen floor. Each tile cost $4 and the adhesive/grouting material costs $17.82. If the contractor pays a total of $545.82 how many ceramic tiles did the contractor purchase
Answer:
132 tiles
Step-by-step explanation:
Each tile cost $4
The adhesive/grouting material costs $17.82.
If the contractor pays a total of $545.82
Let the number of tiles be represented as x
The equation is represented as:
$17.82 + $4 × x = $545.82
17.82 + 4x = 545.82
Collect like terms
4x = 545.82 - 17.82
4x = 528
Divide bother sides by 4
4x/4 = 528/4
x = 132
The number of ceramic tiles the contractor bought = 132 tiles
